+
++++
+
+Ranch `2.0.0-rc.1` has been released!
+
+We are getting very close to releasing Ranch 2.0! As most of
+the tremendous programming work was done by contributor Jan Uhlig,
+I will yield the floor and let him describe what went into this
+great release.
+
+In Ranch 1.x, there is only one supervisor per Ranch listener
+to start and manage connection processes. Under high load
+(many clients rapidly connecting and/or disconnecting), the
+message queue of this one supervisor could becomes congested,
+leading to declining accept rates or a stalled listener.
+
+Ranch 2.0 introduces the `num_conns_sups` option (defaulting
+to the number of acceptors), which allows the message load to
+be divided between the specified number of connection supervisors.
+This improves accept concurrency at the same time.
+
+Another bottleneck is a possible congestion of the syn queue of
+a listening socket. The reason is located within the operating
+system's TCP/IP implementation, and on Linux the `SO_REUSEPORT`
+socket option was introduced to address it. What it boils down
+to is that you can have more than just one socket listening on
+the same port, causing the sockets to be load-balanced when
+accepting connections.
+
+Ranch 1.x always uses a single listening socket per listener,
+shared between the acceptors. With a trick, starting multiple Ranch
+listeners on the same port, it is already possible to make use
+of the `SO_REUSEPORT` feature. But that's not ideal.
+
+Ranch 2.0 introduces the `num_listen_sockets` option, which allows
+to specify the number of listening sockets a Ranch listener should
+employ, without having to use this trick. Whether you can use
+`SO_REUSEPORT` at all and how to enable it depends on your
+operating system, though.
+
+Other changes include proper support for local (Unix Domain) sockets,
+removing the restriction that a listener be suspended to change its
+transport options and much needed improvements to embedded listeners.
+
+In addition we have had patches merged to Erlang/OTP to add support
+for active N to the `ssl` application (requires Erlang/OTP 21.3 or
+above) and fix a number of smaller issues we encountered. We have
+also helped detect and fix a bug in the Windows implementation of
+active N that greatly reduced its performance in some cases.
+
+To ensure that everything works correctly, new tests have been
+written, and some existing tests were updated. A noteworthy addition
+in this area is pitting Ranch against https://github.com/ankhers/havoc[Havoc],
+a resilience testing tool that kills random processes and ports
+in the system.
+
+Cowboy users wishing to try Ranch 2.0.0-rc.1 will need to use Cowboy's
+master branch at this time or wait for the upcoming Cowboy 2.7.0.
+Cowboy has been made compatible with both Ranch 1 and 2.
+
+Last but not least, aside from the changes mentioned above, we
+are currently preparing a https://github.com/juhlig/prometheus_ranch[Prometheus collector]
+for Ranch as well as an accompanying Grafana dashboard.
+
+Ranch 2.0 requires Erlang/OTP 21 or above and is tested and supported
+on Linux, FreeBSD, macOS and Windows.
+
+A complete
+list of changes can be found in the migration guide:
+https://ninenines.eu/docs/en/ranch/2.0/guide/migrating_from_1.7/[Migrating from Ranch 1.7 to 2.0].
+
+You can donate to this project via
+https://salt.bountysource.com/teams/ninenines[BountySource].
+These funds are used to pay for additional servers for
+testing. We will soon add two Raspberry Pi 4 in order
+to have some ARM targets when testing.
+
+As usual, feedback is appreciated, and issues or
+questions should be sent via Github tickets. Thanks!

-
-<p>Cowboy is a lightweight HTTP server.</p>
-
-<p>It is built on top of Ranch. Please see the Ranch guide for more information.</p>
-
-<h2 id="one_process_per_connection">One process per connection</h2>
-
-<p>It uses only one process per connection. The process where your code runs is the process controlling the socket. Using one process instead of two allows for lower memory usage.</p>
-
-<p>Because there can be more than one request per connection with the keepalive feature of HTTP/1.1, that means the same process will be used to handle many requests.</p>
-
-<p>Because of this, you are expected to make sure your process cleans up before terminating the handling of the current request. This may include cleaning up the process dictionary, timers, monitoring and more.</p>
-
-<h2 id="binaries">Binaries</h2>
-
-<p>It uses binaries. Binaries are more efficient than lists for representing strings because they take less memory space. Processing performance can vary depending on the operation. Binaries are known for generally getting a great boost if the code is compiled natively. Please see the HiPE documentation for more details.</p>
-
-<h2 id="date_header">Date header</h2>
-
-<p>Because querying for the current date and time can be expensive, Cowboy generates one <code>Date</code> header value every second, shares it to all other processes, which then simply copy it in the response. This allows compliance with HTTP/1.1 with no actual performance loss.</p>
-
-<h2 id="max_connections">Max connections</h2>
-
-<p>By default the maximum number of active connections is set to a generally accepted big enough number. This is meant to prevent having too many processes performing potentially heavy work and slowing everything else down, or taking up all the memory.</p>
-
-<p>Disabling this feature, by setting the <code>{max_connections, infinity}</code> protocol option, would give you greater performance when you are only processing short-lived requests.</p>

-<h1 class="lined-header"><span>Dealing with broken clients</span></h1>
-
-<p>There exists a very large number of implementations for the HTTP protocol. Most widely used clients, like browsers, follow the standard quite well, but others may not. In particular custom enterprise clients tend to be very badly written.</p>
-
-<p>Cowboy tries to follow the standard as much as possible, but is not trying to handle every possible special cases. Instead Cowboy focuses on the cases reported in the wild, on the public Web.</p>
-
-<p>That means clients that ignore the HTTP standard completely may fail to understand Cowboy's responses. There are of course workarounds. This chapter aims to cover them.</p>
-
-<h2 id="lowercase_headers">Lowercase headers</h2>
-
-<p>Cowboy converts all headers it receives to lowercase, and similarly sends back headers all in lowercase. Some broken HTTP clients have issues with that.</p>
-
-<p>A simple way to solve this is to create an <code>onresponse</code> hook that will format the header names with the expected case.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-capitalize_hook(Status, Headers, Body, Req) ->
-    Headers2 = [{cowboy_bstr:capitalize_token(N), V}
-        || {N, V} <- Headers],
-    {ok, Req2} = cowboy_req:reply(Status, Headers2, Body, Req),
-    Req2.
-]]></script>
-
-<p>Note that SPDY clients do not have that particular issue because the specification explicitly says all headers are lowercase, unlike HTTP which allows any case but treats them as case insensitive.</p>
-
-<h2 id="camel-case_headers">Camel-case headers</h2>
-
-<p>Sometimes it is desirable to keep the actual case used by clients, for example when acting as a proxy between two broken implementations. There is no easy solution for this other than forking the project and editing the <code>cowboy_protocol</code> file directly.</p>
-
-<h2 id="chunked_transfer-encoding">Chunked transfer-encoding</h2>
-
-<p>Sometimes an HTTP client advertises itself as HTTP/1.1 but does not support chunked transfer-encoding. This is invalid behavior, as HTTP/1.1 clients are required to support it.</p>
-
-<p>A simple workaround exists in these cases. By changing the Req object response state to <code>waiting_stream</code>, Cowboy will understand that it must use the identity transfer-encoding when replying, just like if it was an HTTP/1.0 client.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-Req2 = cowboy_req:set(resp_state, waiting_stream).

-<h1 class="lined-header"><span>Using cookies</span></h1>
-
-<p>Cookies are a mechanism allowing applications to maintain state on top of the stateless HTTP protocol.</p>
-
-<p>Cowboy provides facilities for handling cookies. It is highly recommended to use them instead of writing your own, as the implementation of cookies can vary greatly between clients.</p>
-
-<p>Cookies are stored client-side and sent with every subsequent request that matches the domain and path for which they were stored, including requests for static files. For this reason they can incur a cost which must be taken in consideration.</p>
-
-<p>Also consider that, regardless of the options used, cookies are not to be trusted. They may be read and modified by any program on the user's computer, but also by proxies. You should always validate cookie values before using them. Do not store any sensitive information in cookies either.</p>
-
-<p>When explicitly setting the domain, the cookie will be sent for the domain and all subdomains from that domain. Otherwise the current domain will be used. The same is true for the path.</p>
-
-<p>When the server sets cookies, they will only be available for requests that are sent after the client receives the response.</p>
-
-<p>Cookies are sent in HTTP headers, therefore they must have text values. It is your responsibility to encode any other data type. Also note that cookie names are de facto case sensitive.</p>
-
-<p>Cookies can be set for the client session (which generally means until the browser is closed), or it can be set for a number of seconds. Once it expires, or when the server says the cookie must exist for up to 0 seconds, the cookie is deleted by the client. To avoid this while the user is browsing your site, you should set the cookie for every request, essentially resetting the expiration time.</p>
-
-<p>Cookies can be restricted to secure channels. This typically means that such a cookie will only be sent over HTTPS, and that it will only be available by client-side scripts that run from HTTPS webpages.</p>
-
-<p>Finally, cookies can be restricted to HTTP and HTTPS requests, essentially disabling their access from client-side scripts.</p>
-
-<h2 id="setting_cookies">Setting cookies</h2>
-
-<p>By default, cookies you set are defined for the session.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-SessionID = generate_session_id(),
-Req2 = cowboy_req:set_resp_cookie(<<"sessionid">>, SessionID, [], Req).
-]]></script>
-
-<p>You can also make them expire at a specific point in the future.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-SessionID = generate_session_id(),
-Req2 = cowboy_req:set_resp_cookie(<<"sessionid">>, SessionID, [
-    {max_age, 3600}
-], Req).
-]]></script>
-
-<p>You can delete cookies that have already been set. The value is ignored.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-Req2 = cowboy_req:set_resp_cookie(<<"sessionid">>, <<>>, [
-    {max_age, 0}
-], Req).
-]]></script>
-
-<p>You can restrict them to a specific domain and path. For example, the following cookie will be set for the domain <code>my.example.org</code> and all its subdomains, but only on the path <code>/account</code> and all its subdirectories.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-Req2 = cowboy_req:set_resp_cookie(<<"inaccount">>, <<"1">>, [
-    {domain, "my.example.org"},
-    {path, "/account"}
-], Req).
-]]></script>
-
-<p>You can restrict the cookie to secure channels, typically HTTPS.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-SessionID = generate_session_id(),
-Req2 = cowboy_req:set_resp_cookie(<<"sessionid">>, SessionID, [
-    {secure, true}
-], Req).
-]]></script>
-
-<p>You can restrict the cookie to client-server communication only. Such a cookie will not be available to client-side scripts.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-SessionID = generate_session_id(),
-Req2 = cowboy_req:set_resp_cookie(<<"sessionid">>, SessionID, [
-    {http_only, true}
-], Req).
-]]></script>
-
-<p>Cookies may also be set client-side, for example using Javascript.</p>
-
-<h2 id="reading_cookies">Reading cookies</h2>
-
-<p>As we said, the client sends cookies with every request. But unlike the server, the client only sends the cookie name and value.</p>
-
-<p>You can read the value of a cookie.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{CookieVal, Req2} = cowboy_req:cookie(<<"lang">>, Req).
-]]></script>
-
-<p>You can also get a default value returned when the cookie isn't set.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{CookieVal, Req2} = cowboy_req:cookie(<<"lang">>, Req, <<"fr">>).
-]]></script>
-
-<p>And you can obtain all cookies at once as a list of key/value tuples.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{AllCookies, Req2} = cowboy_req:cookies(Req).
-]]></script>

-<h1 class="lined-header"><span>Erlang for beginners</span></h1>
-
-<p>Chances are you are interested in using Cowboy, but have no idea how to write an Erlang program. Fear not! This chapter will help you get started.</p>
-
-<p>We recommend two books for beginners. You should read them both at some point, as they cover Erlang from two entirely different perspectives.</p>
-
-<h2 id="learn_you_some_erlang_for_great_good!">Learn You Some Erlang for Great Good!</h2>
-
-<p>The quickest way to get started with Erlang is by reading a book with the funny name of <a href="http://learnyousomeerlang.com">LYSE</a>, as we affectionately call it.</p>
-
-<p>It will get right into the syntax and quickly answer the questions a beginner would ask themselves, all the while showing funny pictures and making insightful jokes.</p>
-
-<p>You can read an early version of the book online for free, but you really should buy the much more refined paper and ebook versions.</p>
-
-<h2 id="programming_erlang">Programming Erlang</h2>
-
-<p>After writing some code, you will probably want to understand the very concepts that make Erlang what it is today. These are best explained by Joe Armstrong, the godfather of Erlang, in his book <a href="http://pragprog.com/book/jaerlang2/programming-erlang">Programming Erlang</a>.</p>
-
-<p>Instead of going into every single details of the language, Joe focuses on the central concepts behind Erlang, and shows you how they can be used to write a variety of different applications.</p>
-
-<p>At the time of writing, the 2nd edition of the book is in beta, and includes a few details about upcoming Erlang features that cannot be used today. Choose the edition you want, then get reading!</p>

-<h1 class="lined-header"><span>Erlang and the Web</span></h1>
-
-<h2 id="the_web_is_concurrent">The Web is concurrent</h2>
-
-<p>When you access a website there is little concurrency involved. A few connections are opened and requests are sent through these connections. Then the web page is displayed on your screen. Your browser will only open up to 4 or 8 connections to the server, depending on your settings. This isn't much.</p>
-
-<p>But think about it. You are not the only one accessing the server at the same time. There can be hundreds, if not thousands, if not millions of connections to the same server at the same time.</p>
-
-<p>Even today a lot of systems used in production haven't solved the C10K problem (ten thousand concurrent connections). And the ones who did are trying hard to get to the next step, C100K, and are pretty far from it.</p>
-
-<p>Erlang meanwhile has no problem handling millions of connections. At the time of writing there are application servers written in Erlang that can handle more than two million connections on a single server in a real production application, with spare memory and CPU!</p>
-
-<p>The Web is concurrent, and Erlang is a language designed for concurrency, so it is a perfect match.</p>
-
-<p>Of course, various platforms need to scale beyond a few million connections. This is where Erlang's built-in distribution mechanisms come in. If one server isn't enough, add more! Erlang allows you to use the same code for talking to local processes or to processes in other parts of your cluster, which means you can scale very quickly if the need arises.</p>
-
-<p>The Web has large userbases, and the Erlang platform was designed to work in a distributed setting, so it is a perfect match.</p>
-
-<p>Or is it? Surely you can find solutions to handle that many concurrent connections with your favorite language... But all these solutions will break down in the next few years. Why? Firstly because servers don't get any more powerful, they instead get a lot more cores and memory. This is only useful if your application can use them properly, and Erlang is light-years away from anything else in that area. Secondly, today your computer and your phone are online, tomorrow your watch, goggles, bike, car, fridge and tons of other devices will also connect to various applications on the Internet.</p>
-
-<p>Only Erlang is prepared to deal with what's coming.</p>
-
-<h2 id="the_web_is_soft_real_time">The Web is soft real time</h2>
-
-<p>What does soft real time mean, you ask? It means we want the operations done as quickly as possible, and in the case of web applications, it means we want the data propagated fast.</p>
-
-<p>In comparison, hard real time has a similar meaning, but also has a hard time constraint, for example an operation needs to be done in under N milliseconds otherwise the system fails entirely.</p>
-
-<p>Users aren't that needy yet, they just want to get access to their content in a reasonable delay, and they want the actions they make to register at most a few seconds after they submitted them, otherwise they'll start worrying about whether it successfully went through.</p>
-
-<p>The Web is soft real time because taking longer to perform an operation would be seen as bad quality of service.</p>
-
-<p>Erlang is a soft real time system. It will always run processes fairly, a little at a time, switching to another process after a while and preventing a single process to steal resources from all others. This means that Erlang can guarantee stable low latency of operations.</p>
-
-<p>Erlang provides the guarantees that the soft real time Web requires.</p>
-
-<h2 id="the_web_is_asynchronous">The Web is asynchronous</h2>
-
-<p>Long ago, the Web was synchronous because HTTP was synchronous. You fired a request, and then waited for a response. Not anymore. It all began when XmlHttpRequest started being used. It allowed the client to perform asynchronous calls to the server.</p>
-
-<p>Then Websocket appeared and allowed both the server and the client to send data to the other endpoint completely asynchronously. The data is contained within frames and no response is necessary.</p>
-
-<p>Erlang processes work the same. They send each other data contained within messages and then continue running without needing a response. They tend to spend most of their time inactive, waiting for a new message, and the Erlang VM happily activate them when one is received.</p>
-
-<p>It is therefore quite easy to imagine Erlang being good at receiving Websocket frames, which may come in at unpredictable times, pass the data to the responsible processes which are always ready waiting for new messages, and perform the operations required by only activating the required parts of the system.</p>
-
-<p>The more recent Web technologies, like Websocket of course, but also SPDY and HTTP/2.0, are all fully asynchronous protocols. The concept of requests and responses is retained of course, but anything could be sent in between, by both the client or the browser, and the responses could also be received in a completely different order.</p>
-
-<p>Erlang is by nature asynchronous and really good at it thanks to the great engineering that has been done in the VM over the years. It's only natural that it's so good at dealing with the asynchronous Web.</p>
-
-<h2 id="the_web_is_omnipresent">The Web is omnipresent</h2>
-
-<p>The Web has taken a very important part of our lives. We're connected at all times, when we're on our phone, using our computer, passing time using a tablet while in the bathroom... And this isn't going to slow down, every single device at home or on us will be connected.</p>
-
-<p>All these devices are always connected. And with the number of alternatives to give you access to the content you seek, users tend to not stick around when problems arise. Users today want their applications to be always available and if it's having too many issues they just move on.</p>
-
-<p>Despite this, when developers choose a product to use for building web applications, their only concern seem to be "Is it fast?", and they look around for synthetic benchmarks showing which one is the fastest at sending "Hello world" with only a handful concurrent connections. Web benchmarks haven't been representative of reality in a long time, and are drifting further away as time goes on.</p>
-
-<p>What developers should really ask themselves is "Can I service all my users with no interruption?" and they'd find that they have two choices. They can either hope for the best, or they can use Erlang.</p>
-
-<p>Erlang is built for fault tolerance. When writing code in any other language, you have to check all the return values and act accordingly to avoid any unforeseen issues. If you're lucky, you won't miss anything important. When writing Erlang code, you can just check the success condition and ignore all errors. If an error happen, the Erlang process crashes and is then restarted by a special process called a supervisor.</p>
-
-<p>The Erlang developer thus has no need to fear about unhandled errors, and can focus on handling only the errors that should give some feedback to the user and let the system take care of the rest. This also has the advantage of allowing him to write a lot less code, and letting him sleep at night.</p>
-
-<p>Erlang's fault tolerance oriented design is the first piece of what makes it the best choice for the omnipresent, always available Web.</p>
-
-<p>The second piece is Erlang's built-in distribution. Distribution is a key part of building a fault tolerant system, because it allows you to handle bigger failures, like a whole server going down, or even a data center entirely.</p>
-
-<p>Fault tolerance and distribution are important today, and will be vital in the future of the Web. Erlang is ready.</p>
-
-<h2 id="erlang_is_the_ideal_platform_for_the_web">Erlang is the ideal platform for the Web</h2>
-
-<p>Erlang provides all the important features that the Web requires or will require in the near future. Erlang is a perfect match for the Web, and it only makes sense to use it to build web applications.</p>

-
-<p>Erlang is more than a language, it is also an operating system for your applications. Erlang developers rarely write standalone modules, they write libraries or applications, and then bundle those into what is called a release. A release contains the Erlang VM plus all applications required to run the node, so it can be pushed to production directly.</p>
-
-<p>This chapter walks you through all the steps of setting up Cowboy, writing your first application and generating your first release. At the end of this chapter you should know everything you need to push your first Cowboy application to production.</p>
-
-<h2 id="bootstrap">Bootstrap</h2>
-
-<p>We are going to use the <a href="https://github.com/ninenines/erlang.mk">erlang.mk</a> build system. It also offers bootstrap features allowing us to quickly get started without having to deal with minute details.</p>
-
-<p>First, let's create the directory for our application.</p>
-
-<script type="syntaxhighlighter" class="brush: bash"><![CDATA[
-$ mkdir hello_erlang
-$ cd hello_erlang
-]]></script>
-
-<p>Then we need to download <code>erlang.mk</code>. Either use the following command or download it manually.</p>
-
-<script type="syntaxhighlighter" class="brush: bash"><![CDATA[
-$ wget https://raw.githubusercontent.com/ninenines/erlang.mk/master/erlang.mk
-]]></script>
-
-<p>We can now bootstrap our application. Since we are going to generate a release, we will also bootstrap it at the same time.</p>
-
-<script type="syntaxhighlighter" class="brush: bash"><![CDATA[
-$ make -f erlang.mk bootstrap bootstrap-rel
-]]></script>
-
-<p>This creates a Makefile, a base application, and the release files necessary for creating the release. We can already build and start this release.</p>
-
-<script type="syntaxhighlighter" class="brush: bash"><![CDATA[
-$ make
-...
-$ ./_rel/hello_erlang_release/bin/hello_erlang_release console
-...
-([email protected])1>
-]]></script>
-
-<p>Entering the command <code>i().</code> will show the running processes, including one called <code>hello_erlang_sup</code>. This is the supervisor for our application.</p>
-
-<p>The release currently does nothing. In the rest of this chapter we will add Cowboy as a dependency and write a simple "Hello world!" handler.</p>
-
-<h2 id="cowboy_setup">Cowboy setup</h2>
-
-<p>To add Cowboy as a dependency to your application, you need to modify two files: the Makefile and the application resource file.</p>
-
-<p>Modifying the Makefile allows the build system to know it needs to fetch and compile Cowboy. To do that we simply need to add one line to our Makefile to make it look like this:</p>
-
-<script type="syntaxhighlighter" class="brush: plain"><![CDATA[
-PROJECT = hello_erlang
-DEPS = cowboy
-include erlang.mk
-]]></script>
-
-<p>Modifying the application resource file, <code>src/hello_erlang.app.src</code>, allows the build system to know it needs to include Cowboy in the release and start it automatically. This is a different step because some dependencies are only needed during development.</p>
-
-<p>We are simply going to add <code>cowboy</code> to the list of <code>applications</code>, right after <code>stdlib</code>. Don't forget the comma separator.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{application, hello_erlang, [
-	{description, "Hello Erlang!"},
-	{vsn, "0.1.0"},
-	{modules, []},
-	{registered, []},
-	{applications, [
-		kernel,
-		stdlib,
-		cowboy
-	]},
-	{mod, {hello_erlang_app, []}},
-	{env, []}
-]}.
-]]></script>
-
-<p>You may want to set a description for the application while you are editing the file.</p>
-
-<p>If you run <code>make</code> now and start the release, Cowboy will be included and started automatically. This is not enough however, as Cowboy doesn't do anything by default. We still need to tell Cowboy to listen for connections.</p>
-
-<h2 id="listening_for_connections">Listening for connections</h2>

-<p>We will do this when our application starts. It's a two step process. First we need to define and compile the dispatch list, a list of routes that Cowboy will use to map requests to handler modules. Then we tell Cowboy to listen for connections.</p>
-
-<p>Open the <code>src/hello_erlang_app.erl</code> file and add the necessary code to the <code>start/2</code> function to make it look like this:</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-start(_Type, _Args) ->
-	Dispatch = cowboy_router:compile([
-		{'_', [{"/", hello_handler, []}]}
-	]),
-	cowboy:start_http(my_http_listener, 100, [{port, 8080}],
-		[{env, [{dispatch, Dispatch}]}]
-	),
-	hello_erlang_sup:start_link().
-]]></script>
-
-<p>The dispatch list is explained in great details in the <a href="/docs/en/cowboy/1.0/guide/routing">Routing</a> chapter. For this tutorial we map the path <code>/</code> to the handler module <code>hello_handler</code>. This module doesn't exist yet, we still have to write it.</p>
-
-<p>If you build the release, start it and open <a href="http://localhost:8080">http://localhost:8080</a> now, you will get an error because the module is missing. Any other URL, like <a href="http://localhost:8080/test">http://localhost:8080/test</a>, will result in a 404 error.</p>
-
-<h2 id="handling_requests">Handling requests</h2>
-
-<p>Cowboy features different kinds of handlers, including REST and Websocket handlers. For this tutorial we will use a plain HTTP handler.</p>
-
-<p>First, let's generate a handler from a template.</p>
-
-<script type="syntaxhighlighter" class="brush: bash"><![CDATA[
-$ make new t=cowboy_http n=hello_handler
-]]></script>
-
-<p>You can then open the <code>src/hello_handler.erl</code> file and modify the <code>handle/2</code> function like this to send a reply.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-handle(Req, State=#state{}) ->
-	{ok, Req2} = cowboy_req:reply(200,
-		[{<<"content-type">>, <<"text/plain">>}],
-		<<"Hello Erlang!">>,
-		Req),
-	{ok, Req2, State}.
-]]></script>
-
-<p>What the above code does is send a <code>200 OK</code> reply, with the <code>content-type</code> header set to <code>text/plain</code> and the response body set to <code>Hello Erlang!</code>.</p>
-
-<p>If you build the release, start it and open <a href="http://localhost:8080">http://localhost:8080</a> in your browser, you should get a nice <code>Hello Erlang!</code> displayed!</p>

-<h1 class="lined-header"><span>Hooks</span></h1>
-
-<p>Cowboy provides two hooks. <code>onrequest</code> is called once the request line and headers have been received. <code>onresponse</code> is called just before sending the response.</p>
-
-<h2 id="onrequest">Onrequest</h2>
-
-<p>The <code>onrequest</code> hook is called as soon as Cowboy finishes fetching the request headers. It occurs before any other processing, including routing. It can be used to perform any modification needed on the request object before continuing with the processing. If a reply is sent inside this hook, then Cowboy will move on to the next request, skipping any subsequent handling.</p>
-
-<p>This hook is a function that takes a request object as argument, and returns a request object. This function MUST NOT crash. Cowboy will not send any reply if a crash occurs in this function.</p>
-
-<p>You can specify the <code>onrequest</code> hook when creating the listener, inside the request options.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-cowboy:start_http(my_http_listener, 100,
-    [{port, 8080}],
-    [
-        {env, [{dispatch, Dispatch}]},
-        {onrequest, fun ?MODULE:debug_hook/1}
-    ]
-).
-]]></script>
-
-<p>The following hook function prints the request object everytime a request is received. This can be useful for debugging, for example.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-debug_hook(Req) ->
-    erlang:display(Req),
-    Req.
-]]></script>
-
-<p>Make sure to always return the last request object obtained.</p>
-
-<h2 id="onresponse">Onresponse</h2>
-
-<p>The <code>onresponse</code> hook is called right before sending the response to the socket. It can be used for the purposes of logging responses, or for modifying the response headers or body. The best example is providing custom error pages.</p>
-
-<p>Note that like the <code>onrequest</code> hook, this function MUST NOT crash. Cowboy may or may not send a reply if this function crashes. If a reply is sent, the hook MUST explicitly provide all headers that are needed.</p>
-
-<p>You can specify the <code>onresponse</code> hook when creating the listener.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-cowboy:start_http(my_http_listener, 100,
-    [{port, 8080}],
-    [
-        {env, [{dispatch, Dispatch}]},
-        {onresponse, fun ?MODULE:custom_404_hook/4}
-    ]
-).
-]]></script>
-
-<p>The following hook function will provide a custom body for 404 errors when it has not been provided before, and will let Cowboy proceed with the default response otherwise.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-custom_404_hook(404, Headers, <<>>, Req) ->
-    Body = <<"404 Not Found.">>,
-    Headers2 = lists:keyreplace(<<"content-length">>, 1, Headers,
-        {<<"content-length">>, integer_to_list(byte_size(Body))}),
-    {ok, Req2} = cowboy_req:reply(404, Headers2, Body, Req),
-    Req2;
-custom_404_hook(_, _, _, Req) ->
-    Req.
-]]></script>
-
-<p>Again, make sure to always return the last request object obtained.</p>

-<h1 class="lined-header"><span>Handling plain HTTP requests</span></h1>
-
-<p>The simplest way to handle a request is by writing a plain HTTP handler. It is modeled after Erlang/OTP's gen_server behaviour, although simplified, as Cowboy will simply call the three callbacks sequentially.</p>
-
-<h2 id="initialization">Initialization</h2>
-
-<p>The first callback, <code>init/3</code>, is common to all handlers, as it is used to identify the type of handler. Plain HTTP handlers just return <code>ok</code>.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-init(_Type, Req, _Opts) ->
-    {ok, Req, no_state}.
-]]></script>
-
-<p>This function receives the name of the transport and protocol modules used for processing the request. They can be used to quickly dismiss requests. For example the following handler will crash when accessed using TCP instead of SSL.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-init({ssl, _}, Req, _Opts) ->
-    {ok, Req, no_state}.
-]]></script>
-
-<p>This function also receives the options associated with this route that you configured previously. If your handler does not use options, then it is recommended you match the value <code>[]</code> directly to quickly detect configuration errors.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-init(_Type, Req, []) ->
-    {ok, Req, no_state}.
-]]></script>
-
-<p>You do not need to validate the options unless they are user configured. If they are, and there's a configuration error, you may choose to crash. For example, this will crash if the required <code>lang</code> option is not found.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-init(_Type, Req, Opts) ->
-    {_, _Lang} = lists:keyfind(lang, 1, Opts),
-    {ok, Req, no_state}.
-]]></script>
-
-<p>If your users are unlikely to figure out the issue without explanations, then you should send a more meaningful error back to the user. Since we already replied to the user, there's no need for us to continue with the handler code, so we use the <code>shutdown</code> return value to stop early.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-init(_Type, Req, Opts) ->
-    case lists:keyfind(lang, 1, Opts) of
-        false ->
-            {ok, Req2} = cowboy_req:reply(500, [
-                {<<"content-type">>, <<"text/plain">>}
-            ], "Missing option 'lang'.", Req),
-            {shutdown, Req2, no_state};
-        _ ->
-            {ok, Req, no_state}
-    end.
-]]></script>
-
-<p>Once the options have been validated, we can use them safely. So we need to pass them onward to the rest of the handler. That's what the third element of the return tuple, the state, is for.</p>
-
-<p>We recommend that you create a state record for this. The record will make your handler code clearer and will allow you to better use Dialyzer for type checking.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
--record(state, {
-    lang :: en | fr
-    %% More fields here.
-}).
-
-init(_Type, Req, Opts) ->
-    {_, Lang} = lists:keyfind(lang, 1, Opts),
-    {ok, Req, #state{lang=Lang}}.
-]]></script>
-
-<h2 id="handling_the_request">Handling the request</h2>
-
-<p>The second callback, <code>handle/2</code>, is specific to plain HTTP handlers. It's where you, wait for it, handle the request.</p>
-
-<p>A handle function that does nothing would look like this:</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-handle(Req, State) ->
-    {ok, Req, State}.
-]]></script>
-
-<p>There's no other return value. To obtain information about the request, or send a response, you would use the Req object here. The Req object is documented in its own chapter.</p>
-
-<p>The following handle function will send a fairly original response.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-handle(Req, State) ->
-    {ok, Req2} = cowboy_req:reply(200, [
-        {<<"content-type">>, <<"text/plain">>}
-    ], <<"Hello World!">>, Req),
-    {ok, Req2, State}.
-]]></script>
-
-<h2 id="cleaning_up">Cleaning up</h2>
-
-<p>The third and last callback, <code>terminate/3</code>, will most likely be empty in your handler.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-terminate(_Reason, Req, State) ->
-    ok.
-]]></script>
-
-<p>This callback is strictly reserved for any required cleanup. You cannot send a response from this function. There is no other return value.</p>
-
-<p>If you used the process dictionary, timers, monitors or may be receiving messages, then you can use this function to clean them up, as Cowboy might reuse the process for the next keep-alive request.</p>
-
-<p>The chances of any of this happening in your handler are pretty thin however. The use of the process dictionary is discouraged in Erlang code in general. And if you need to use timers, monitors or to receive messages, you are better off with a loop handler, a different kind of handler meant specifically for this use.</p>
-
-<p>This function is still available should you need it. It will always be called.</p>

-<h1 class="lined-header"><span>The life of a request</span></h1>
-
-<p>This chapter explains the different steps a request goes through until a response is sent, along with details of the Cowboy implementation.</p>
-
-<h2 id="request/response">Request/response</h2>
-
-<p>As you already know, HTTP clients connect to the server and send a request for a resource; the server then sends a response containing the resource if it could obtain it.</p>
-
-<p>Before the server can send the resource, however, it needs to perform many different operations to read the request, find the resource, prepare the response being sent and often other related operations the user can add like writing logs.</p>
-
-<p>Requests take the following route in Cowboy:</p>
-
-<p><img title="HTTP request/response flowchart" src="/docs/en/cowboy/1.0/guide/http_req_resp.png"/></p>
-
-<p>This shows the default middlewares, but they may be configured differently in your setup. The dark green indicates the points where you can hook your own code, the light green is the Cowboy code that you can of course configure as needed.</p>
-
-<p>The <code>acceptor</code> is the part of the server that accepts the connection and create an Erlang process to handle it. The <code>parser</code> then starts reading from the socket and handling requests as they come until the socket is closed.</p>
-
-<p>A response may be sent at many different points in the life of the request. If Cowboy can't parse the request, it gives up with an error response. If the router can't find the resource, it sends a not found error. Your own code can of course send a response at any time.</p>
-
-<p>When a response is sent, you can optionally modify it or act upon it by enabling the <code>onresponse</code> hook. By default the response is sent directly to the client.</p>
-
-<h2 id="and_then?">And then?</h2>
-
-<p>Behavior depends on what protocol is in use.</p>
-
-<p>HTTP/1.0 can only process one request per connection, so Cowboy will close the connection immediately after it sends the response.</p>
-
-<p>HTTP/1.1 allows the client to request that the server keeps the connection alive. This mechanism is described in the next section.</p>
-
-<p>SPDY is designed to allow sending multiple requests asynchronously on the same connection. Details on what this means for your application is described in this chapter.</p>
-
-<h2 id="keep-alive_(http/1.1)">Keep-alive (HTTP/1.1)</h2>
-
-<p>With HTTP/1.1, the connection may be left open for subsequent requests to come. This mechanism is called <code>keep-alive</code>.</p>
-
-<p>When the client sends a request to the server, it includes a header indicating whether it would like to leave the socket open. The server may or may not accept, indicating its choice by sending the same header in the response.</p>
-
-<p>Cowboy will include this header automatically in all responses to HTTP/1.1 requests. You can however force the closing of the socket if you want. When Cowboy sees you want to send a <code>connection: close</code> header, it will not override it and will close the connection as soon as the reply is sent.</p>
-
-<p>This snippet will force Cowboy to close the connection.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{ok, Req2} = cowboy_req:reply(200, [
-    {<<"connection">>, <<"close">>},
-], <<"Closing the socket in 3.. 2.. 1..">>, Req).
-]]></script>
-
-<p>Cowboy will only accept a certain number of new requests on the same connection. By default it will run up to 100 requests. This number can be changed by setting the <code>max_keepalive</code> configuration value when starting an HTTP listener.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-cowboy:start_http(my_http_listener, 100, [{port, 8080}], [
-        {env, [{dispatch, Dispatch}]},
-        {max_keepalive, 5}
-]).
-]]></script>
-
-<p>Cowboy implements the keep-alive mechanism by reusing the same process for all requests. This allows Cowboy to save memory. This works well because most code will not have any side effect impacting subsequent requests. But it also means you need to clean up if you do have code with side effects. The <code>terminate/3</code> function can be used for this purpose.</p>
-
-<h2 id="pipelining_(http/1.1)">Pipelining (HTTP/1.1)</h2>
-
-<p>While HTTP is designed as a sequential protocol, with the client sending a request and then waiting for the response from the server, nothing prevents the client from sending more requests to the server without waiting for the response, due to how sockets work. The server still handles the requests sequentially and sends the responses in the same order.</p>
-
-<p>This mechanism is called pipelining. It allows reducing latency when a client needs to request many resources at the same time. This is used by browsers when requesting static files for example.</p>
-
-<p>This is handled automatically by the server.</p>
-
-<h2 id="asynchronous_requests_(spdy)">Asynchronous requests (SPDY)</h2>
-
-<p>In SPDY, the client can send a request at any time. And the server can send a response at any time too.</p>
-
-<p>This means for example that the client does not need to wait for a request to be fully sent to send another, it is possible to interleave a request with the request body of another request. The same is true with responses. Responses may also be sent in a different order.</p>
-
-<p>Because requests and responses are fully asynchronous, Cowboy creates a new process for each request, and these processes are managed by another process that handles the connection itself.</p>
-
-<p>SPDY servers may also decide to send resources to the client before the client requests them. This is especially useful for sending static files associated with the HTML page requested, as this reduces the latency of the overall response. Cowboy does not support this particular mechanism at this point, however.</p>

-
-<p>Cowboy is a small, fast and modular HTTP server written in Erlang.</p>
-
-<p>Cowboy aims to provide a complete HTTP stack, including its derivatives SPDY, Websocket and REST. Cowboy currently supports HTTP/1.0, HTTP/1.1, Websocket (all implemented drafts + standard) and Webmachine-based REST.</p>
-
-<p>Cowboy is a high quality project. It has a small code base, is very efficient (both in latency and memory use) and can easily be embedded in another application.</p>
-
-<p>Cowboy is clean Erlang code. It includes hundreds of tests and its code is fully compliant with the Dialyzer. It is also well documented and features both a Function Reference and a User Guide.</p>
-
-<h2 id="prerequisites">Prerequisites</h2>
-
-<p>No Erlang knowledge is required for reading this guide. The reader will be introduced to Erlang concepts and redirected to reference material whenever necessary.</p>
-
-<p>Knowledge of the HTTP protocol is recommended but not required, as it will be detailed throughout the guide.</p>
-
-<h2 id="supported_platforms">Supported platforms</h2>
-
-<p>Cowboy is tested and supported on Linux.</p>
-
-<p>Cowboy has been reported to work on other platforms, but we make no guarantee that the experience will be safe and smooth. You are advised to perform the necessary testing and security audits prior to deploying on other platforms.</p>
-
-<p>Cowboy is developed for Erlang/OTP R16B01, R16B02, R16B03-1, 17.0 and 17.1.2.</p>
-
-<p>Cowboy may be compiled on other Erlang versions with small source code modifications but there is no guarantee that it will work as expected.</p>
-
-<h2 id="versioning">Versioning</h2>
-
-<p>Cowboy uses <a href="http://semver.org/">Semantic Versioning 2.0.0</a>.</p>
-
-<h2 id="conventions">Conventions</h2>
-
-<p>In the HTTP protocol, the method name is case sensitive. All standard method names are uppercase.</p>
-
-<p>Header names are case insensitive. Cowboy converts all the request header names to lowercase, and expects your application to provide lowercase header names in the response.</p>
-
-<p>The same applies to any other case insensitive value.</p>

-<h1 class="lined-header"><span>Loop handlers</span></h1>
-
-<p>Loop handlers are a special kind of HTTP handlers used when the response can not be sent right away. The handler enters instead a receive loop waiting for the right message before it can send a response.</p>
-
-<p>Loop handlers are used for requests where a response might not be immediately available, but where you would like to keep the connection open for a while in case the response arrives. The most known example of such practice is known as long-polling.</p>
-
-<p>Loop handlers can also be used for requests where a response is partially available and you need to stream the response body while the connection is open. The most known example of such practice is known as server-sent events.</p>
-
-<p>While the same can be accomplished using plain HTTP handlers, it is recommended to use loop handlers because they are well-tested and allow using built-in features like hibernation and timeouts.</p>
-
-<p>Loop handlers essentially wait for one or more Erlang messages and feed these messages to the <code>info/3</code> callback. It also features the <code>init/3</code> and <code>terminate/3</code> callbacks which work the same as for plain HTTP handlers.</p>
-
-<h2 id="initialization">Initialization</h2>
-
-<p>The <code>init/3</code> function must return a <code>loop</code> tuple to enable loop handler behavior. This tuple may optionally contain a timeout value and/or the atom <code>hibernate</code> to make the process enter hibernation until a message is received.</p>
-
-<p>This snippet enables the loop handler.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-init(_Type, Req, _Opts) ->
-    {loop, Req, undefined_state}.
-]]></script>
-
-<p>However it is largely recommended that you set a timeout value. The next example sets a timeout value of 30s and also makes the process hibernate.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-init(_Type, Req, _Opts) ->
-    {loop, Req, undefined_state, 30000, hibernate}.
-]]></script>
-
-<h2 id="receive_loop">Receive loop</h2>
-
-<p>Once initialized, Cowboy will wait for messages to arrive in the process' mailbox. When a message arrives, Cowboy calls the <code>info/3</code> function with the message, the Req object and the handler's state.</p>
-
-<p>The following snippet sends a reply when it receives a <code>reply</code> message from another process, or waits for another message otherwise.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-info({reply, Body}, Req, State) ->
-    {ok, Req2} = cowboy_req:reply(200, [], Body, Req),
-    {ok, Req2, State};
-info(_Msg, Req, State) ->
-    {loop, Req, State, hibernate}.
-]]></script>
-
-<p>Do note that the <code>reply</code> tuple here may be any message and is simply an example.</p>
-
-<p>This callback may perform any necessary operation including sending all or parts of a reply, and will subsequently return a tuple indicating if more messages are to be expected.</p>
-
-<p>The callback may also choose to do nothing at all and just skip the message received.</p>
-
-<p>If a reply is sent, then the <code>ok</code> tuple should be returned. This will instruct Cowboy to end the request.</p>
-
-<p>Otherwise a <code>loop</code> tuple should be returned.</p>
-
-<h2 id="streaming_loop">Streaming loop</h2>
-
-<p>Another common case well suited for loop handlers is streaming data received in the form of Erlang messages. This can be done by initiating a chunked reply in the <code>init/3</code> callback and then using <code>cowboy_req:chunk/2</code> every time a message is received.</p>
-
-<p>The following snippet does exactly that. As you can see a chunk is sent every time a <code>chunk</code> message is received, and the loop is stopped by sending an <code>eof</code> message.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-init(_Type, Req, _Opts) ->
-	{ok, Req2} = cowboy_req:chunked_reply(200, [], Req),
-    {loop, Req2, undefined_state}.
-
-info(eof, Req, State) ->
-    {ok, Req, State};
-info({chunk, Chunk}, Req, State) ->
-    ok = cowboy_req:chunk(Chunk, Req),
-    {loop, Req, State};
-info(_Msg, Req, State) ->
-    {loop, Req, State}.
-]]></script>
-
-<h2 id="cleaning_up">Cleaning up</h2>
-
-<p>It is recommended that you set the connection header to <code>close</code> when replying, as this process may be reused for a subsequent request.</p>
-
-<p>Please refer to the <a href="/docs/en/cowboy/1.0/guide/http_handlers">HTTP handlers chapter</a> for general instructions about cleaning up.</p>
-
-<h2 id="timeout">Timeout</h2>
-
-<p>By default Cowboy will not attempt to close the connection if there is no activity from the client. This is not always desirable, which is why you can set a timeout. Cowboy will close the connection if no data was received from the client after the configured time. The timeout only needs to be set once and can't be modified afterwards.</p>
-
-<p>Because the request may have had a body, or may be followed by another request, Cowboy is forced to buffer all data it receives. This data may grow to become too large though, so there is a configurable limit for it. The default buffer size is of 5000 bytes, but it may be changed by setting the <code>loop_max_buffer</code> middleware environment value.</p>
-
-<h2 id="hibernate">Hibernate</h2>
-
-<p>To save memory, you may hibernate the process in between messages received. This is done by returning the atom <code>hibernate</code> as part of the <code>loop</code> tuple callbacks normally return. Just add the atom at the end and Cowboy will hibernate accordingly.</p>

-<h1 class="lined-header"><span>Middlewares</span></h1>
-
-<p>Cowboy delegates the request processing to middleware components. By default, two middlewares are defined, for the routing and handling of the request, as is detailed in most of this guide.</p>
-
-<p>Middlewares give you complete control over how requests are to be processed. You can add your own middlewares to the mix or completely change the chain of middlewares as needed.</p>
-
-<p>Cowboy will execute all middlewares in the given order, unless one of them decides to stop processing.</p>
-
-<h2 id="usage">Usage</h2>
-
-<p>Middlewares only need to implement a single callback: <code>execute/2</code>. It is defined in the <code>cowboy_middleware</code> behavior.</p>
-
-<p>This callback has two arguments. The first is the <code>Req</code> object. The second is the environment.</p>
-
-<p>Middlewares can return one of four different values:</p>
-
-<ul>
-<li><code>{ok, Req, Env}</code> to continue the request processing</li>
-<li><code>{suspend, Module, Function, Args}</code> to hibernate</li>
-<li><code>{halt, Req}</code> to stop processing and move on to the next request</li>
-<li><code>{error, StatusCode, Req}</code> to reply an error and close the socket</li>
-</ul>
-
-<p>Of note is that when hibernating, processing will resume on the given MFA, discarding all previous stacktrace. Make sure you keep the <code>Req</code> and <code>Env</code> in the arguments of this MFA for later use.</p>
-
-<p>If an error happens during middleware processing, Cowboy will not try to send an error back to the socket, the process will just crash. It is up to the middleware to make sure that a reply is sent if something goes wrong.</p>
-
-<h2 id="configuration">Configuration</h2>
-
-<p>The middleware environment is defined as the <code>env</code> protocol option. In the previous chapters we saw it briefly when we needed to pass the routing information. It is a list of tuples with the first element being an atom and the second any Erlang term.</p>
-
-<p>Two values in the environment are reserved:</p>
-
-<ul>
-<li><code>listener</code> contains the name of the listener</li>
-<li><code>result</code> contains the result of the processing</li>
-</ul>
-
-<p>The <code>listener</code> value is always defined. The <code>result</code> value can be set by any middleware. If set to anything other than <code>ok</code>, Cowboy will not process any subsequent requests on this connection.</p>
-
-<p>The middlewares that come with Cowboy may define or require other environment values to perform.</p>
-
-<p>You can update the environment by calling the <code>cowboy:set_env/3</code> convenience function, adding or replacing a value in the environment.</p>
-
-<h2 id="routing_middleware">Routing middleware</h2>
-
-<p>The routing middleware requires the <code>dispatch</code> value. If routing succeeds, it will put the handler name and options in the <code>handler</code> and <code>handler_opts</code> values of the environment, respectively.</p>
-
-<h2 id="handler_middleware">Handler middleware</h2>
-
-<p>The handler middleware requires the <code>handler</code> and <code>handler_opts</code> values. It puts the result of the request handling into <code>result</code>.</p>

-<h1 class="lined-header"><span>The modern Web</span></h1>
-
-<p>Let's take a look at various technologies from the beginnings of the Web up to this day, and get a preview of what's coming next.</p>
-
-<p>Cowboy is compatible with all the technology cited in this chapter except of course HTTP/2.0 which has no implementation in the wild at the time of writing.</p>
-
-<h2 id="the_prehistoric_web">The prehistoric Web</h2>
-
-<p>HTTP was initially created to serve HTML pages and only had the GET method for retrieving them. This initial version is documented and is sometimes called HTTP/0.9. HTTP/1.0 defined the GET, HEAD and POST methods, and was able to send data with POST requests.</p>
-
-<p>HTTP/1.0 works in a very simple way. A TCP connection is first established to the server. Then a request is sent. Then the server sends a response back and closes the connection.</p>
-
-<p>Suffice to say, HTTP/1.0 is not very efficient. Opening a TCP connection takes some time, and pages containing many assets load much slower than they could because of this.</p>
-
-<p>Most improvements done in recent years focused on reducing this load time and reducing the latency of the requests.</p>
-
-<h2 id="http/1.1">HTTP/1.1</h2>
-
-<p>HTTP/1.1 quickly followed and added a keep-alive mechanism to allow using the same connection for many requests, as well as streaming capabilities, allowing an endpoint to send a body in well defined chunks.</p>
-
-<p>HTTP/1.1 defines the OPTIONS, GET, HEAD, POST, PUT, DELETE, TRACE and CONNECT methods. The PATCH method was added in more recent years. It also improves the caching capabilities with the introduction of many headers.</p>
-
-<p>HTTP/1.1 still works like HTTP/1.0 does, except the connection can be kept alive for subsequent requests. This however allows clients to perform what is called as pipelining: sending many requests in a row, and then processing the responses which will be received in the same order as the requests.</p>
-
-<h2 id="rest">REST</h2>
-
-<p>The design of HTTP/1.1 was influenced by the REST architectural style. REST, or REpresentational State Transfer, is a style of architecture for loosely connected distributed systems.</p>
-
-<p>REST defines constraints that systems must obey to in order to be RESTful. A system which doesn't follow all the constraints cannot be considered RESTful.</p>
-
-<p>REST is a client-server architecture with a clean separation of concerns between the client and the server. They communicate by referencing resources. Resources can be identified, but also manipulated. A resource representation has a media type and information about whether it can be cached and how. Hypermedia determines how resources are related and how they can be used. REST is also stateless. All requests contain the complete information necessary to perform the action.</p>
-
-<p>HTTP/1.1 defines all the methods, headers and semantics required to implement RESTful systems.</p>
-
-<p>REST is most often used when designing web application APIs which are generally meant to be used by executable code directly.</p>
-
-<h2 id="xmlhttprequest">XmlHttpRequest</h2>
-
-<p>Also know as AJAX, this technology allows Javascript code running on a web page to perform asynchronous requests to the server. This is what started the move from static websites to dynamic web applications.</p>
-
-<p>XmlHttpRequest still performs HTTP requests under the hood, and then waits for a response, but the Javascript code can continue to run until the response arrives. It will then receive the response through a callback previously defined.</p>
-
-<p>This is of course still requests initiated by the client, the server still had no way of pushing data to the client on its own, so new technology appeared to allow that.</p>
-
-<h2 id="long-polling">Long-polling</h2>
-
-<p>Polling was a technique used to overcome the fact that the server cannot push data directly to the client. Therefore the client had to repeatedly create a connection, make a request, get a response, then try again a few seconds later. This is overly expensive and adds an additional delay before the client receives the data.</p>
-
-<p>Polling was necessary to implement message queues and other similar mechanisms, where a user must be informed of something when it happens, rather than when he refreshes the page next. A typical example would be a chat application.</p>
-
-<p>Long-polling was created to reduce the server load by creating less connections, but also to improve latency by getting the response back to the client as soon as it becomes available on the server.</p>
-
-<p>Long-polling works in a similar manner to polling, except the request will not get a response immediately. Instead the server leaves it open until it has a response to send. After getting the response, the client creates a new request and gets back to waiting.</p>
-
-<p>You probably guessed by now that long-polling is a hack, and like most hacks it can suffer from unforeseen issues, in this case it doesn't always play well with proxies.</p>
-
-<h2 id="html5">HTML5</h2>
-
-<p>HTML5 is, of course, the HTML version after HTML4. But HTML5 emerged to solve a specific problem: dynamic web applications.</p>
-
-<p>HTML was initially created to write web pages which compose a website. But soon people and companies wanted to use HTML to write more and more complex websites, eventually known as web applications. They are for example your news reader, your email client in the browser, or your video streaming website.</p>
-
-<p>Because HTML wasn't enough, they started using proprietary solutions, often implemented using plug-ins. This wasn't perfect of course, but worked well enough for most people.</p>
-
-<p>However, the needs for a standard solution eventually became apparent. The browser needed to be able to play media natively. It needed to be able to draw anything. It needed an efficient way of streaming events to the server, but also receiving events from the server.</p>
-
-<p>The solution went on to become HTML5. At the time of writing it is being standardized.</p>
-
-<h2 id="eventsource">EventSource</h2>
-
-<p>EventSource, sometimes also called Server-Sent Events, is a technology allowing servers to push data to HTML5 applications.</p>
-
-<p>EventSource is one-way communication channel from the server to the client. The client has no means to talk to the server other than by using HTTP requests.</p>
-
-<p>It consists of a Javascript object allowing setting up an EventSource connection to the server, and a very small protocol for sending events to the client on top of the HTTP/1.1 connection.</p>
-
-<p>EventSource is a lightweight solution that only works for UTF-8 encoded text data. Binary data and text data encoded differently are not allowed by the protocol. A heavier but more generic approach can be found in Websocket.</p>
-
-<h2 id="websocket">Websocket</h2>
-
-<p>Websocket is a protocol built on top of HTTP/1.1 that provides a two-ways communication channel between the client and the server. Communication is asynchronous and can occur concurrently.</p>
-
-<p>It consists of a Javascript object allowing setting up a Websocket connection to the server, and a binary based protocol for sending data to the server or the client.</p>
-
-<p>Websocket connections can transfer either UTF-8 encoded text data or binary data. The protocol also includes support for implementing a ping/pong mechanism, allowing the server and the client to have more confidence that the connection is still alive.</p>
-
-<p>A Websocket connection can be used to transfer any kind of data, small or big, text or binary. Because of this Websocket is sometimes used for communication between systems.</p>
-
-<h2 id="spdy">SPDY</h2>
-
-<p>SPDY is an attempt to reduce page loading time by opening a single connection per server, keeping it open for subsequent requests, and also by compressing the HTTP headers to reduce the size of requests.</p>
-
-<p>SPDY is compatible with HTTP/1.1 semantics, and is actually just a different way of performing HTTP requests and responses, by using binary frames instead of a text-based protocol. SPDY also allows the server to send extra responses following a request. This is meant to allow sending the resources associated with the request before the client requests them, saving latency when loading websites.</p>
-
-<p>SPDY is an experiment that has proven successful and is used as the basis for the HTTP/2.0 standard.</p>
-
-<p>Browsers make use of TLS Next Protocol Negotiation to upgrade to a SPDY connection seamlessly if the protocol supports it.</p>
-
-<p>The protocol itself has a few shortcomings which are being fixed in HTTP/2.0.</p>
-
-<h2 id="http/2.0">HTTP/2.0</h2>
-
-<p>HTTP/2.0 is the long-awaited update to the HTTP/1.1 protocol. It is based on SPDY although a lot has been improved at the time of writing.</p>
-
-<p>HTTP/2.0 is an asynchronous two-ways communication channel between two endpoints.</p>
-
-<p>It is planned to be ready late 2014.</p>

-<h1 class="lined-header"><span>Introduction to multipart</span></h1>
-
-<p>Multipart originates from MIME, an Internet standard that extends the format of emails. Multipart messages are a container for parts of any content-type.</p>
-
-<p>For example, a multipart message may have a part containing text and a second part containing an image. This is what allows you to attach files to emails.</p>
-
-<p>In the context of HTTP, multipart is most often used with the <code>multipart/form-data</code> content-type. This is the content-type you have to use when you want browsers to be allowed to upload files through HTML forms.</p>
-
-<p>Multipart is of course not required for uploading files, it is only required when you want to do so through HTML forms.</p>
-
-<h2 id="structure">Structure</h2>
-
-<p>A multipart message is a list of parts. Parts may contain either a multipart message or a non-multipart content-type. This allows parts to be arranged in a tree structure, although this is a rare case as far as the Web is concerned.</p>
-
-<h2 id="form-data">Form-data</h2>
-
-<p>In the normal case, when a form is submitted, the browser will use the <code>application/x-www-form-urlencoded</code> content-type. This type is just a list of keys and values and is therefore not fit for uploading files.</p>
-
-<p>That's where the <code>multipart/form-data</code> content-type comes in. When the form is configured to use this content-type, the browser will use one part of the message for each form field. This means that a file input field will be sent in its own part, but the same applies to all other kinds of fields.</p>
-
-<p>A form with a text input, a file input and a select choice box will result in a multipart message with three parts, one for each field.</p>
-
-<p>The browser does its best to determine the content-type of the files it sends this way, but you should not rely on it for determining the contents of the file. Proper investigation of the contents is recommended.</p>

-
-<h1 class="lined-header"><span>Multipart requests</span></h1>
-
-<p>You can read and parse multipart messages using the Req object directly.</p>
-
-<p>Cowboy defines two functions that allows you to get information about each part and read their contents.</p>
-
-<h2 id="checking_the_content-type">Checking the content-type</h2>
-
-<p>While there is a variety of multipart messages, the most common on the Web is <code>multipart/form-data</code>. It's the type of message being sent when an HTML form allows uploading files.</p>
-
-<p>You can quickly figure out if a multipart message has been sent by parsing the <code>content-type</code> header.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{ok, {<<"multipart">>, <<"form-data">>, _}, Req2}
-    = cowboy_req:parse_header(<<"content-type">>, Req).
-]]></script>
-
-<h2 id="reading_a_multipart_message">Reading a multipart message</h2>
-
-<p>To read a message you have to iterate over all its parts. Then, for each part, you can inspect its headers and read its body.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-multipart(Req) ->
-    case cowboy_req:part(Req) of
-        {ok, _Headers, Req2} ->
-            {ok, _Body, Req3} = cowboy_req:part_body(Req2),
-            multipart(Req3);
-        {done, Req2} ->
-            Req2
-    end.
-]]></script>
-
-<p>Parts do not have a size limit. When a part body is too big, Cowboy will return what it read so far and allow you to continue if you wish to do so.</p>
-
-<p>The function <code>cow_multipart:form_data/1</code> can be used to quickly obtain information about a part from a <code>multipart/form-data</code> message. This function will tell you if the part is for a normal field or if it is a file being uploaded.</p>
-
-<p>This can be used for example to allow large part bodies for files but crash when a normal field is too large.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-multipart(Req) ->
-    case cowboy_req:part(Req) of
-        {ok, Headers, Req2} ->
-            Req4 = case cow_multipart:form_data(Headers) of
-                {data, _FieldName} ->
-                    {ok, _Body, Req3} = cowboy_req:part_body(Req2),
-                    Req3;
-                {file, _FieldName, _Filename, _CType, _CTransferEncoding} ->
-                    stream_file(Req2)
-            end,
-            multipart(Req4);
-        {done, Req2} ->
-            Req2
-    end.
-
-stream_file(Req) ->
-    case cowboy_req:part_body(Req) of
-        {ok, _Body, Req2} ->
-            Req2;
-        {more, _Body, Req2} ->
-            stream_file(Req2)
-    end.
-]]></script>
-
-<p>By default the body chunk Cowboy will return is limited to 8MB. This can of course be overriden. Both functions can take a second argument, the same list of options that will be passed to <code>cowboy_req:body/2</code> function.</p>
-
-<h2 id="skipping_unwanted_parts">Skipping unwanted parts</h2>
-
-<p>If you do not want to read a part's body, you can skip it. Skipping is easy. If you do not call the function to read the part's body, Cowboy will automatically skip it when you request the next part.</p>
-
-<p>The following snippet reads all part headers and skips all bodies:</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-multipart(Req) ->
-    case cowboy_req:part(Req) of
-        {ok, _Headers, Req2} ->
-            multipart(Req2);
-        {done, Req2} ->
-            Req2
-    end.
-]]></script>
-
-<p>Similarly, if you start reading the body and it ends up being too big, you can simply continue with the next part, Cowboy will automatically skip what remains.</p>
-
-<p>Note that the skipping rate may not be adequate for your application. If you observe poor performance when skipping, you might want to consider manually skipping by calling the <code>cowboy_req:part_body/1</code> function directly.</p>
-
-<p>And if you started reading the message but decide that you do not need the remaining parts, you can simply stop reading entirely and Cowboy will automatically figure out what to do.</p>

-<p>Almost all the calls to the <code>cowboy_req</code> module will return an updated request object. Just like you would keep the updated <code>State</code> variable in a gen_server, you MUST keep the updated <code>Req</code> variable in a Cowboy handler. Cowboy will use this object to know whether a response has been sent when the handler has finished executing.</p>
-
-<p>The Req object allows accessing both immutable and mutable state. This means that calling some of the functions twice will not produce the same result. For example, when streaming the request body, the function will return the body by chunks, one at a time, until there is none left.</p>
-
-<p>It also caches the result of operations performed on the immutable state. That means that some calls will give a result much faster when called many times.</p>
-
-<h2 id="overview_of_the_cowboy_req_interface">Overview of the cowboy_req interface</h2>
-
-<p>The <code>cowboy_req</code> interface is divided in four groups of functions, each having a well defined return type signature common to the entire group.</p>
-
-<p>The first group, access functions, will always return <code>{Value, Req}</code>. The group includes all the following functions: <code>binding/{2,3}</code>, <code>bindings/1</code>, <code>body_length/1</code>, <code>cookie/{2,3}</code>, <code>cookies/1</code>, <code>header/{2,3}</code>, <code>headers/1</code>, <code>host/1</code>, <code>host_info/1</code>, <code>host_url/1</code>, <code>meta/{2,3}</code>, <code>method/1</code>, <code>path/1</code>, <code>path_info/1</code>, <code>peer/1</code>, <code>port/1</code>, <code>qs/1</code>, <code>qs_val/{2,3}</code>, <code>qs_vals/1</code>, <code>url/1</code>, <code>version/1</code>.</p>
-
-<p>The second group, question functions, will always return a <code>boolean()</code>. The group includes the following three functions: <code>has_body/1</code>, <code>has_resp_body/1</code>, <code>has_resp_header/2</code>.</p>
-
-<p>The third group contains the functions that manipulate the socket or perform operations that may legitimately fail. They may return <code>{Result, Req}</code>, <code>{Result, Value, Req}</code> or <code>{error, atom()}</code>. This includes the following functions: <code>body/{1,2}</code>, <code>body_qs/{1,2}</code>, <code>chunked_reply/{2,3}</code>, <code>parse_header/{2,3}</code>, <code>part/{1,2}</code>, <code>part_body/{1,2}</code> and <code>reply/{2,3,4}</code>. Finally, the group also includes the <code>chunk/2</code> and <code>continue/1</code> functions which always return <code>ok</code>.</p>
-
-<p>The final group modifies the Req object state without performing any immediate operations. As these functions can't fail, they always return a new <code>Req</code> directly. This includes the following functions: <code>compact/1</code>, <code>delete_resp_header/2</code>, <code>set_meta/3</code>, <code>set_resp_body/2</code>, <code>set_resp_body_fun/{2,3}</code>, <code>set_resp_cookie/4</code>, <code>set_resp_header/3</code>.</p>
-
-<p>This chapter covers most of the first group, plus a few other functions. The next few chapters cover cookies handling, reading the request body and sending a response.</p>
-
-<h2 id="request">Request</h2>
-
-<p>When a client performs a request, it first sends a few required values. They are sent differently depending on the protocol being used, but the intent is the same. They indicate to the server the type of action it wants to do and how to locate the resource to perform it on.</p>
-
-<p>The method identifies the action. Standard methods include GET, HEAD, OPTIONS, PATCH, POST, PUT, DELETE. Method names are case sensitive.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{Method, Req2} = cowboy_req:method(Req).
-]]></script>
-
-<p>The host, port and path parts of the URL identify the resource being accessed. The host and port information may not be available if the client uses HTTP/1.0.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{Host, Req2} = cowboy_req:host(Req),
-{Port, Req3} = cowboy_req:port(Req2),
-{Path, Req4} = cowboy_req:path(Req3).
-]]></script>
-
-<p>The version used by the client can of course also be obtained.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{Version, Req2} = cowboy_req:version(Req).
-]]></script>
-
-<p>Do note however that clients claiming to implement one version of the protocol does not mean they implement it fully, or even properly.</p>
-
-<h2 id="bindings">Bindings</h2>
-
-<p>After routing the request, bindings are available. Bindings are these parts of the host or path that you chose to extract when defining the routes of your application.</p>
-
-<p>You can fetch a single binding. The value will be <code>undefined</code> if the binding doesn't exist.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{Binding, Req2} = cowboy_req:binding(my_binding, Req).
-]]></script>
-
-<p>If you need a different value when the binding doesn't exist, you can change the default.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{Binding, Req2} = cowboy_req:binding(my_binding, Req, 42).
-]]></script>
-
-<p>You can also obtain all bindings in one call. They will be returned as a list of key/value tuples.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{AllBindings, Req2} = cowboy_req:bindings(Req).
-]]></script>
-
-<p>If you used <code>...</code> at the beginning of the route's pattern for the host, you can retrieve the matched part of the host. The value will be <code>undefined</code> otherwise.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{HostInfo, Req2} = cowboy_req:host_info(Req).
-]]></script>
-
-<p>Similarly, if you used <code>...</code> at the end of the route's pattern for the path, you can retrieve the matched part, or get <code>undefined</code> otherwise.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{PathInfo, Req2} = cowboy_req:path_info(Req).
-]]></script>
-
-<h2 id="query_string">Query string</h2>
-
-<p>The query string can be obtained directly.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{Qs, Req2} = cowboy_req:qs(Req).
-]]></script>
-
-<p>You can also requests only one value.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{QsVal, Req2} = cowboy_req:qs_val(<<"lang">>, Req).
-]]></script>
-
-<p>If that value is optional, you can define a default to simplify your task.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{QsVal, Req2} = cowboy_req:qs_val(<<"lang">>, Req, <<"en">>).
-]]></script>
-
-<p>Finally, you can obtain all query string values.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{AllValues, Req2} = cowboy_req:qs_vals(Req).
-]]></script>
-
-<h2 id="request_url">Request URL</h2>
-
-<p>You can reconstruct the full URL of the resource.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{URL, Req2} = cowboy_req:url(Req).
-]]></script>
-
-<p>You can also obtain only the base of the URL, excluding the path and query string.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{BaseURL, Req2} = cowboy_req:host_url(Req).
-]]></script>
-
-<h2 id="headers">Headers</h2>
-
-<p>Cowboy allows you to obtain the header values as string, or parsed into a more meaningful representation.</p>
-
-<p>This will get the string value of a header.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{HeaderVal, Req2} = cowboy_req:header(<<"content-type">>, Req).
-]]></script>
-
-<p>You can of course set a default in case the header is missing.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{HeaderVal, Req2}
-    = cowboy_req:header(<<"content-type">>, Req, <<"text/plain">>).
-]]></script>
-
-<p>And also obtain all headers.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{AllHeaders, Req2} = cowboy_req:headers(Req).
-]]></script>
-
-<p>To parse the previous header, simply call <code>parse_header/{2,3}</code> where you would call <code>header/{2,3}</code> otherwise. Note that the return value changes and includes the result of the operation as the first element of the returned tuple. A successful parse returns <code>ok</code>.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{ok, ParsedVal, Req2} = cowboy_req:parse_header(<<"content-type">>, Req).
-]]></script>
-
-<p>When Cowboy doesn't know how to parse the given header, the result of the operation will be <code>undefined</code> and the string value will be returned instead.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{undefined, HeaderVal, Req2}
-    = cowboy_req:parse_header(<<"unicorn-header">>, Req).
-]]></script>
-
-<p>When parsing fails, <code>{error, Reason}</code> is returned instead.</p>
-
-<p>You can of course define a default value. Note that the default value you specify here is the parsed value you'd like to get by default.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{ok, ParsedVal, Req2}
-    = cowboy_req:parse_header(<<"content-type">>, Req,
-    {<<"text">>, <<"plain">>, []}).
-]]></script>
-
-<p>The list of known headers and default values is defined in the manual. Also note that the result of parsing is cached, so calling this function multiple times for the same values will not have a significant performance impact.</p>
-
-<h2 id="meta">Meta</h2>
-
-<p>Cowboy will sometimes associate some meta information with the request. Built-in meta values are listed in the manual for their respective modules.</p>
-
-<p>This will get a meta value. The returned value will be <code>undefined</code> if it isn't defined.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{MetaVal, Req2} = cowboy_req:meta(websocket_version, Req).
-]]></script>
-
-<p>You can change the default value if needed.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{MetaVal, Req2} = cowboy_req:meta(websocket_version, Req, 13).
-]]></script>
-
-<p>You can also define your own meta values. The name must be an <code>atom()</code>.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-Req2 = cowboy_req:set_meta(the_answer, 42, Req).
-]]></script>
-
-<h2 id="peer">Peer</h2>
-
-<p>You can obtain the peer address and port number. This is not necessarily the actual IP and port of the client, but rather the one of the machine that connected to the server.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{{IP, Port}, Req2} = cowboy_req:peer(Req).
-]]></script>
-
-<h2 id="reducing_the_memory_footprint">Reducing the memory footprint</h2>
-
-<p>When you are done reading information from the request object and know you are not going to access it anymore, for example when using long-polling or Websocket, you can use the <code>compact/1</code> function to remove most of the data from the request object and free memory.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-Req2 = cowboy_req:compact(Req).
-]]></script>
-
-<p>You will still be able to send a reply if needed.</p>

-<h1 class="lined-header"><span>Reading the request body</span></h1>
-
-<p>The Req object also allows you to read the request body.</p>
-
-<p>Because the request body can be of any size, all body reading operations will only work once, as Cowboy will not cache the result of these operations.</p>
-
-<p>Cowboy will not attempt to read the body until you do. If handler execution ends without reading it, Cowboy will simply skip it.</p>
-
-<p>Cowboy provides different ways to read the request body. You can read it directly, stream it, but also read and parse in a single call for form urlencoded formats or multipart. All of these except multipart are covered in this chapter. Multipart is covered later on in the guide.</p>
-
-<h2 id="check_for_request_body">Check for request body</h2>
-
-<p>You can check whether a body was sent with the request.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-cowboy_req:has_body(Req).
-]]></script>
-
-<p>It will return <code>true</code> if there is a request body, and <code>false</code> otherwise.</p>
-
-<p>Note that it is generally safe to assume that a body is sent for <code>POST</code>, <code>PUT</code> and <code>PATCH</code> requests, without having to explicitly check for it.</p>
-
-<h2 id="request_body_length">Request body length</h2>
-
-<p>You can obtain the body length if it was sent with the request.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{Length, Req2} = cowboy_req:body_length(Req).
-]]></script>
-
-<p>The value returned will be <code>undefined</code> if the length couldn't be figured out from the request headers. If there's a body but no length is given, this means that the chunked transfer-encoding was used. You can read chunked bodies by using the stream functions.</p>
-
-<h2 id="reading_the_body">Reading the body</h2>
-
-<p>You can read the whole body directly in one call.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{ok, Body, Req2} = cowboy_req:body(Req).
-]]></script>
-
-<p>By default, Cowboy will attempt to read up to a size of 8MB. You can override this limit as needed.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{ok, Body, Req2} = cowboy_req:body(Req, [{length, 100000000}]).
-]]></script>
-
-<p>You can also disable it.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{ok, Body, Req2} = cowboy_req:body(Req, [{length, infinity}]).
-]]></script>
-
-<p>It is recommended that you do not disable it for public facing websites.</p>
-
-<p>If the body is larger than the limit, then Cowboy will return a <code>more</code> tuple instead, allowing you to stream it if you would like to.</p>
-
-<h2 id="streaming_the_body">Streaming the body</h2>
-
-<p>You can stream the request body by chunks.</p>
-
-<p>Cowboy returns a <code>more</code> tuple when there is more body to be read, and an <code>ok</code> tuple for the last chunk. This allows you to loop over all chunks.</p>

-            io:format("~s", [Data]),
-            body_to_console(Req2)
-    end.
-]]></script>
-
-<p>You can of course set the <code>length</code> option to configure the size of chunks.</p>
-
-<h2 id="rate_of_data_transmission">Rate of data transmission</h2>
-
-<p>You can control the rate of data transmission by setting options when calling body functions. This applies not only to the functions described in this chapter, but also to the multipart functions.</p>
-
-<p>The <code>read_length</code> option defines the maximum amount of data to be received from the socket at once, in bytes.</p>
-
-<p>The <code>read_timeout</code> option defines the time Cowboy waits before that amount is received, in milliseconds.</p>
-
-<h2 id="transfer_and_content_decoding">Transfer and content decoding</h2>
-
-<p>Cowboy will by default decode the chunked transfer-encoding if any. It will not decode any content-encoding by default.</p>
-
-<p>The first time you call a body function you can set the <code>transfer_decode</code> and <code>content_decode</code> options. If the body was already started being read these options are simply ignored.</p>
-
-<p>The following example shows how to set both options.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{ok, Req2} = cowboy_req:body(Req, [
-    {transfer_decode, fun transfer_decode/2, TransferState},
-    {content_decode, fun content_decode/1}
-]).
-]]></script>
-
-<h2 id="reading_a_form_urlencoded_body">Reading a form urlencoded body</h2>
-
-<p>You can directly obtain a list of key/value pairs if the body was sent using the application/x-www-form-urlencoded content-type.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{ok, KeyValues, Req2} = cowboy_req:body_qs(Req).
-]]></script>
-
-<p>You can then retrieve an individual value from that list.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{_, Lang} = lists:keyfind(lang, 1, KeyValues).
-]]></script>
-
-<p>You should not attempt to match on the list as the order of the values is undefined.</p>
-
-<p>By default Cowboy will reject bodies with a size above 64KB when using this function. You can override this limit by setting the <code>length</code> option.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{ok, KeyValues, Req2} = cowboy_req:body_qs(Req,
-    [{length, 2000000}]).
-]]></script>

-<h1 class="lined-header"><span>Designing a resource handler</span></h1>
-
-<p>This chapter aims to provide you with a list of questions you must answer in order to write a good resource handler. It is meant to be usable as a step by step guide.</p>
-
-<h2 id="the_service">The service</h2>
-
-<p>Can the service become unavailable, and when it does, can we detect it? For example database connectivity problems may be detected early. We may also have planned outages of all or parts of the system. Implement the <code>service_available</code> callback.</p>
-
-<p>What HTTP methods does the service implement? Do we need more than the standard OPTIONS, HEAD, GET, PUT, POST, PATCH and DELETE? Are we not using one of those at all? Implement the <code>known_methods</code> callback.</p>
-
-<h2 id="type_of_resource_handler">Type of resource handler</h2>
-
-<p>Am I writing a handler for a collection of resources, or for a single resource?</p>
-
-<p>The semantics for each of these are quite different. You should not mix collection and single resource in the same handler.</p>
-
-<h2 id="collection_handler">Collection handler</h2>
-
-<p>Skip this section if you are not doing a collection.</p>
-
-<p>Is the collection hardcoded or dynamic? For example if you use the route <code>/users</code> for the collection of users then the collection is hardcoded; if you use <code>/forums/:category</code> for the collection of threads then it isn't. When the collection is hardcoded you can safely assume the resource always exists.</p>
-
-<p>What methods should I implement?</p>
-
-<p>OPTIONS is used to get some information about the collection. It is recommended to allow it even if you do not implement it, as Cowboy has a default implementation built-in.</p>
-
-<p>HEAD and GET are used to retrieve the collection. If you allow GET, also allow HEAD as there's no extra work required to make it work.</p>
-
-<p>POST is used to create a new resource inside the collection. Creating a resource by using POST on the collection is useful when resources may be created before knowing their URI, usually because parts of it are generated dynamically. A common case is some kind of auto incremented integer identifier.</p>
-
-<p>The next methods are more rarely allowed.</p>
-
-<p>PUT is used to create a new collection (when the collection isn't hardcoded), or replace the entire collection.</p>
-
-<p>DELETE is used to delete the entire collection.</p>
-
-<p>PATCH is used to modify the collection using instructions given in the request body. A PATCH operation is atomic. The PATCH operation may be used for such things as reordering; adding, modifying or deleting parts of the collection.</p>
-
-<h2 id="single_resource_handler">Single resource handler</h2>
-
-<p>Skip this section if you are doing a collection.</p>
-
-<p>What methods should I implement?</p>
-
-<p>OPTIONS is used to get some information about the resource. It is recommended to allow it even if you do not implement it, as Cowboy has a default implementation built-in.</p>
-
-<p>HEAD and GET are used to retrieve the resource. If you allow GET, also allow HEAD as there's no extra work required to make it work.</p>
-
-<p>POST is used to update the resource.</p>
-
-<p>PUT is used to create a new resource (when it doesn't already exist) or replace the resource.</p>
-
-<p>DELETE is used to delete the resource.</p>
-
-<p>PATCH is used to modify the resource using instructions given in the request body. A PATCH operation is atomic. The PATCH operation may be used for adding, removing or modifying specific values in the resource.</p>
-
-<h2 id="the_resource">The resource</h2>
-
-<p>Following the above discussion, implement the <code>allowed_methods</code> callback.</p>
-
-<p>Does the resource always exist? If it may not, implement the <code>resource_exists</code> callback.</p>
-
-<p>Do I need to authenticate the client before they can access the resource? What authentication mechanisms should I provide? This may include form-based, token-based (in the URL or a cookie), HTTP basic, HTTP digest, SSL certificate or any other form of authentication. Implement the <code>is_authorized</code> callback.</p>
-
-<p>Do I need fine-grained access control? How do I determine that they are authorized access? Handle that in your <code>is_authorized</code> callback.</p>
-
-<p>Can access to a resource be forbidden regardless of access being authorized? A simple example of that is censorship of a resource. Implement the <code>forbidden</code> callback.</p>
-
-<p>Is there any constraints on the length of the resource URI? For example the URI may be used as a key in storage and may have a limit in length. Implement <code>uri_too_long</code>.</p>
-
-<h2 id="representations">Representations</h2>
-
-<p>What media types do I provide? If text based, what charsets are provided? What languages do I provide?</p>
-
-<p>Implement the mandatory <code>content_types_provided</code>. Prefix the callbacks with <code>to_</code> for clarity. For example <code>to_html</code> or <code>to_text</code>.</p>
-
-<p>Implement the <code>languages_provided</code> or <code>charsets_provided</code> callbacks if applicable.</p>
-
-<p>Is there any other header that may make the representation of the resource vary? Implement the <code>variances</code> callback.</p>
-
-<p>Depending on your choices for caching content, you may want to implement one or more of the <code>generate_etag</code>, <code>last_modified</code> and <code>expires</code> callbacks.</p>
-
-<p>Do I want the user or user agent to actively choose a representation available? Send a list of available representations in the response body and implement the <code>multiple_choices</code> callback.</p>
-
-<h2 id="redirections">Redirections</h2>
-
-<p>Do I need to keep track of what resources were deleted? For example you may have a mechanism where moving a resource leaves a redirect link to its new location. Implement the <code>previously_existed</code> callback.</p>
-
-<p>Was the resource moved, and is the move temporary? If it is explicitly temporary, for example due to maintenance, implement the <code>moved_temporarily</code> callback. Otherwise, implement the <code>moved_permanently</code> callback.</p>
-
-<h2 id="the_request">The request</h2>
-
-<p>Do we need to perform extra checks to make sure the request is valid? Cowboy will do many checks when receiving the request already, do we need more? Note that this only applies to the request-line and headers of the request, and not the body. Implement <code>malformed_request</code>.</p>
-
-<p>May there be a request body? Will I know its size? What's the maximum size of the request body I'm willing to accept? Implement <code>valid_entity_length</code>.</p>
-
-<p>Finally, take a look at the sections corresponding to the methods you are implementing.</p>
-
-<h2 id="options_method">OPTIONS method</h2>
-
-<p>Cowboy by default will send back a list of allowed methods. Do I need to add more information to the response? Implement the <code>options</code> method.</p>
-
-<h2 id="get_and_head_methods">GET and HEAD methods</h2>
-
-<p>If you implement the methods GET and/or HEAD, you must implement one <code>ProvideResource</code> callback for each content-type returned by the <code>content_types_provided</code> callback.</p>
-
-<h2 id="put,_post_and_patch_methods">PUT, POST and PATCH methods</h2>
-
-<p>If you implement the methods PUT, POST and/or PATCH, you must implement the <code>content_types_accepted</code> callback, and one <code>AcceptResource</code> callback for each content-type it returns. Prefix the <code>AcceptResource</code> callback names with <code>from_</code> for clarity. For example <code>from_html</code> or <code>from_json</code>.</p>
-
-<p>Do we want to allow the POST method to create individual resources directly through their URI (like PUT)? Implement the <code>allow_missing_post</code> callback. It is recommended to explicitly use PUT in these cases instead.</p>
-
-<p>May there be conflicts when using PUT to create or replace a resource? Do we want to make sure that two updates around the same time are not cancelling one another? Implement the <code>is_conflict</code> callback.</p>
-
-<h2 id="delete_methods">DELETE methods</h2>
-
-<p>If you implement the method DELETE, you must implement the <code>delete_resource</code> callback.</p>
-
-<p>When <code>delete_resource</code> returns, is the resource completely removed from the server, including from any caching service? If not, and/or if the deletion is asynchronous and we have no way of knowing it has been completed yet, implement the <code>delete_completed</code> callback.</p>

-
-<h1 class="lined-header"><span>Sending a response</span></h1>
-
-<p>The Req object also allows you to send a response.</p>
-
-<p>You can only send one response. Any other attempt will trigger a crash. The response may be sent in one go or with its body streamed by chunks of arbitrary size.</p>
-
-<p>You can also set headers or the response body in advance and Cowboy will use them when you finally do reply.</p>
-
-<h2 id="reply">Reply</h2>
-
-<p>You can send a reply with no particular headers or body. Cowboy will make sure to send the mandatory headers with the response.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{ok, Req2} = cowboy_req:reply(200, Req).
-]]></script>
-
-<p>You can define headers to be sent with the response. Note that header names must be lowercase. Again, Cowboy will make sure to send the mandatory headers with the response.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{ok, Req2} = cowboy_req:reply(303, [
-    {<<"location">>, <<"http://ninenines.eu">>}
-], Req).
-]]></script>
-
-<p>You can override headers that Cowboy would send otherwise. Any header set by the user will be used over the ones set by Cowboy. For example, you can advertise yourself as a different server.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{ok, Req2} = cowboy_req:reply(200, [
-    {<<"server">>, <<"yaws">>}
-], Req).
-]]></script>
-
-<p>We also saw earlier how to force close the connection by overriding the connection header.</p>
-
-<p>Finally, you can also send a body with the response. Cowboy will automatically set the content-length header if you do. We recommend that you set the content-type header so the client may know how to read the body.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{ok, Req2} = cowboy_req:reply(200, [
-    {<<"content-type">>, <<"text/plain">>}
-], "Hello world!", Req).
-]]></script>
-
-<p>Here is the same example but sending HTML this time.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{ok, Req2} = cowboy_req:reply(200, [
-    {<<"content-type">>, <<"text/html">>}
-], "<html><head>Hello world!</head><body><p>Hats off!</p></body></html>", Req).
-]]></script>
-
-<p>Note that the reply is sent immediately.</p>
-
-<h2 id="chunked_reply">Chunked reply</h2>
-
-<p>You can also stream the response body. First, you need to initiate the reply by sending the response status code. Then you can send the body in chunks of arbitrary size.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{ok, Req2} = cowboy_req:chunked_reply(200, Req),
-ok = cowboy_req:chunk("Hello...", Req2),
-ok = cowboy_req:chunk("chunked...", Req2),
-ok = cowboy_req:chunk("world!!", Req2).
-]]></script>
-
-<p>You should make sure to match on <code>ok</code> as an error may be returned.</p>
-
-<p>While it is possible to send a chunked response without a content-type header, it is still recommended. You can set this header or any other just like for normal replies.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{ok, Req2} = cowboy_req:chunked_reply(200, [
-    {<<"content-type">>, <<"text/html">>}
-], Req),
-ok = cowboy_req:chunk("<html><head>Hello world!</head>", Req2),
-ok = cowboy_req:chunk("<body><p>Hats off!</p></body></html>", Req2).
-]]></script>
-
-<p>Note that the reply and each chunk following it are sent immediately.</p>
-
-<h2 id="preset_response_headers">Preset response headers</h2>
-
-<p>You can define response headers in advance. They will be merged into the headers given in the reply call. Headers in the reply call override preset response headers which override the default Cowboy headers.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-Req2 = cowboy_req:set_resp_header(<<"allow">>, "GET", Req).
-]]></script>
-
-<p>You can check if a response header has already been set. This will only check the response headers that you set, and not the ones Cowboy will add when actually sending the reply.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-cowboy_req:has_resp_header(<<"allow">>, Req).
-]]></script>
-
-<p>It will return <code>true</code> if the header is defined, and <code>false</code> otherwise.</p>
-
-<p>Finally, you can also delete a preset response header if needed. If you do, it will not be sent.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-Req2 = cowboy_req:delete_resp_header(<<"allow">>, Req).
-]]></script>
-
-<h2 id="preset_response_body">Preset response body</h2>
-
-<p>You can set the response body in advance. Note that this body will be ignored if you then choose to send a chunked reply, or if you send a reply with an explicit body.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-Req2 = cowboy_req:set_resp_body("Hello world!", Req).
-]]></script>
-
-<p>You can also set a fun that will be called when it is time to send the body. There are three different ways of doing that.</p>
-
-<p>If you know the length of the body that needs to be sent, you should specify it, as it will help clients determine the remaining download time and allow them to inform the user.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-F = fun (Socket, Transport) ->
-    Transport:send(Socket, "Hello world!")
-end,
-Req2 = cowboy_req:set_resp_body_fun(12, F, Req).
-]]></script>
-
-<p>If you do not know the length of the body, you should use a chunked response body fun instead.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-F = fun (SendChunk) ->
-    Body = lists:duplicate(random:uniform(1024, $a)),
-    SendChunk(Body)
-end,
-Req2 = cowboy_req:set_resp_body_fun(chunked, F, Req).
-]]></script>
-
-<p>Finally, you can also send data on the socket directly, without knowing the length in advance. Cowboy may be forced to close the connection at the end of the response though depending on the protocol capabilities.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-F = fun (Socket, Transport) ->
-    Body = lists:duplicate(random:uniform(1024, $a)),
-    Transport:send(Socket, Body)
-end,
-Req2 = cowboy_req:set_resp_body_fun(F, Req).
-]]></script>
-
-<h2 id="sending_files">Sending files</h2>
-
-<p>You can send files directly from disk without having to read them. Cowboy will use the <code>sendfile</code> syscall when possible, which means that the file is sent to the socket directly from the kernel, which is a lot more performant than doing it from userland.</p>
-
-<p>Again, it is recommended to set the size of the file if it can be known in advance.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-F = fun (Socket, Transport) ->
-    Transport:sendfile(Socket, "priv/styles.css")
-end,
-Req2 = cowboy_req:set_resp_body_fun(FileSize, F, Req).
-]]></script>
-
-<p>Please see the Ranch guide for more information about sending files.</p>

-<h1 class="lined-header"><span>REST flowcharts</span></h1>
-
-<p>This chapter will explain the REST handler state machine through a number of different diagrams.</p>
-
-<p>There are four main paths that requests may follow. One for the method OPTIONS; one for the methods GET and HEAD; one for the methods PUT, POST and PATCH; and one for the method DELETE.</p>
-
-<p>All paths start with the "Start" diagram, and all paths excluding the OPTIONS path go through the "Content negotiation" diagram and optionally the "Conditional requests" diagram if the resource exists.</p>
-
-<p>The red squares refer to another diagram. The light green squares indicate a response. Other squares may be either a callback or a question answered by Cowboy itself. Green arrows tend to indicate the default behavior if the callback is undefined.</p>
-
-<h2 id="start">Start</h2>
-
-<p>All requests start from here.</p>
-
-<p><img title="REST starting flowchart" src="/docs/en/cowboy/1.0/guide/rest_start.png"/></p>
-
-<p>A series of callbacks are called in succession to perform a general checkup of the service, the request line and request headers.</p>
-
-<p>The request body, if any, is not expected to have been received for any of these steps. It is only processed at the end of the "PUT, POST and PATCH methods" diagram, when all conditions have been met.</p>
-
-<p>The <code>known_methods</code> and <code>allowed_methods</code> callbacks return a list of methods. Cowboy then checks if the request method is in the list, and stops otherwise.</p>
-
-<p>The <code>is_authorized</code> callback may be used to check that access to the resource is authorized. Authentication may also be performed as needed. When authorization is denied, the return value from the callback must include a challenge applicable to the requested resource, which will be sent back to the client in the www-authenticate header.</p>
-
-<p>This diagram is immediately followed by either the "OPTIONS method" diagram when the request method is OPTIONS, or the "Content negotiation" diagram otherwise.</p>
-
-<h2 id="options_method">OPTIONS method</h2>
-
-<p>This diagram only applies to OPTIONS requests.</p>
-
-<p><img title="REST OPTIONS method flowchart" src="/docs/en/cowboy/1.0/guide/rest_options.png"/></p>
-
-<p>The <code>options</code> callback may be used to add information about the resource, such as media types or languages provided; allowed methods; any extra information. A response body may also be set, although clients should not be expected to read it.</p>
-
-<p>If the <code>options</code> callback is not defined, Cowboy will send a response containing the list of allowed methods by default.</p>
-
-<h2 id="content_negotiation">Content negotiation</h2>
-
-<p>This diagram applies to all request methods other than OPTIONS. It is executed right after the "Start" diagram is completed.</p>
-

-<p>The purpose of these steps is to determine an appropriate representation to be sent back to the client.</p>
-
-<p>The request may contain any of the accept header; the accept-language header; or the accept-charset header. When present, Cowboy will parse the headers and then call the corresponding callback to obtain the list of provided content-type, language or charset for this resource. It then automatically select the best match based on the request.</p>
-
-<p>If a callback is not defined, Cowboy will select the content-type, language or charset that the client prefers.</p>
-
-<p>The <code>content_types_provided</code> also returns the name of a callback for every content-type it accepts. This callback will only be called at the end of the "GET and HEAD methods" diagram, when all conditions have been met.</p>
-
-<p>The selected content-type, language and charset are saved as meta values in the Req object. You <em>should</em> use the appropriate representation if you set a response body manually (alongside an error code, for example).</p>
-
-<p>This diagram is immediately followed by the "GET and HEAD methods" diagram, the "PUT, POST and PATCH methods" diagram, or the "DELETE method" diagram, depending on the method.</p>
-
-<h2 id="get_and_head_methods">GET and HEAD methods</h2>
-
-<p>This diagram only applies to GET and HEAD requests.</p>
-
-<p>For a description of the <code>cond</code> step, please see the "Conditional requests" diagram.</p>
-
-<p><img title="REST GET/HEAD methods flowchart" src="/docs/en/cowboy/1.0/guide/rest_get_head.png"/></p>
-
-<p>When the resource exists, and the conditional steps succeed, the resource can be retrieved.</p>
-
-<p>Cowboy prepares the response by first retrieving metadata about the representation, then by calling the <code>ProvideResource</code> callback. This is the callback you defined for each content-types you returned from <code>content_types_provided</code>. This callback returns the body that will be sent back to the client, or a fun if the body must be streamed.</p>
-
-<p>When the resource does not exist, Cowboy will figure out whether the resource existed previously, and if so whether it was moved elsewhere in order to redirect the client to the new URI.</p>
-
-<p>The <code>moved_permanently</code> and <code>moved_temporarily</code> callbacks must return the new location of the resource if it was in fact moved.</p>
-
-<h2 id="put,_post_and_patch_methods">PUT, POST and PATCH methods</h2>
-
-<p>This diagram only applies to PUT, POST and PATCH requests.</p>
-
-<p>For a description of the <code>cond</code> step, please see the "Conditional requests" diagram.</p>
-
-<p><img title="REST PUT/POST/PATCH methods flowchart" src="/docs/en/cowboy/1.0/guide/rest_put_post_patch.png"/></p>
-
-<p>When the resource exists, first the conditional steps are executed. When that succeeds, and the method is PUT, Cowboy will call the <code>is_conflict</code> callback. This function can be used to prevent potential race conditions, by locking the resource for example.</p>
-
-<p>Then all three methods reach the <code>content_types_accepted</code> step that we will describe in a few paragraphs.</p>
-
-<p>When the resource does not exist, and the method is PUT, Cowboy will check for conflicts and then move on to the <code>content_types_accepted</code> step. For other methods, Cowboy will figure out whether the resource existed previously, and if so whether it was moved elsewhere. If the resource is truly non-existent, the method is POST and the call for <code>allow_missing_post</code> returns <code>true</code>, then Cowboy will move on to the <code>content_types_accepted</code> step. Otherwise the request processing ends there.</p>
-
-<p>The <code>moved_permanently</code> and <code>moved_temporarily</code> callbacks must return the new location of the resource if it was in fact moved.</p>
-
-<p>The <code>content_types_accepted</code> returns a list of content-types it accepts, but also the name of a callback for each of them. Cowboy will select the appropriate callback for processing the request body and call it.</p>
-
-<p>This callback may return one of three different return values.</p>
-
-<p>If an error occurred while processing the request body, it must return <code>false</code> and Cowboy will send an appropriate error response.</p>
-
-<p>If the method is POST, then you may return <code>true</code> with an URI of where the resource has been created. This is especially useful for writing handlers for collections.</p>
-
-<p>Otherwise, return <code>true</code> to indicate success. Cowboy will select the appropriate response to be sent depending on whether a resource has been created, rather than modified, and on the availability of a location header or a body in the response.</p>
-
-<h2 id="delete_method">DELETE method</h2>
-
-<p>This diagram only applies to DELETE requests.</p>
-
-<p>For a description of the <code>cond</code> step, please see the "Conditional requests" diagram.</p>
-
-<p><img title="REST DELETE method flowchart" src="/docs/en/cowboy/1.0/guide/rest_delete.png"/></p>
-
-<p>When the resource exists, and the conditional steps succeed, the resource can be deleted.</p>
-
-<p>Deleting the resource is a two steps process. First the callback <code>delete_resource</code> is executed. Use this callback to delete the resource.</p>
-
-<p>Because the resource may be cached, you must also delete all cached representations of this resource in the system. This operation may take a while though, so you may return before it finished.</p>
-
-<p>Cowboy will then call the <code>delete_completed</code> callback. If you know that the resource has been completely deleted from your system, including from caches, then you can return <code>true</code>. If any doubts persist, return <code>false</code>. Cowboy will assume <code>true</code> by default.</p>
-
-<p>To finish, Cowboy checks if you set a response body, and depending on that, sends the appropriate response.</p>
-
-<p>When the resource does not exist, Cowboy will figure out whether the resource existed previously, and if so whether it was moved elsewhere in order to redirect the client to the new URI.</p>
-
-<p>The <code>moved_permanently</code> and <code>moved_temporarily</code> callbacks must return the new location of the resource if it was in fact moved.</p>
-
-<h2 id="conditional_requests">Conditional requests</h2>
-
-<p>This diagram applies to all request methods other than OPTIONS. It is executed right after the <code>resource_exists</code> callback, when the resource exists.</p>
-
-<p><img title="REST conditional requests flowchart" src="/docs/en/cowboy/1.0/guide/rest_cond.png"/></p>
-
-<p>A request becomes conditional when it includes either of the if-match header; the if-unmodified-since header; the if-none-match header; or the if-modified-since header.</p>
-
-<p>If the condition fails, the request ends immediately without any retrieval or modification of the resource.</p>
-
-<p>The <code>generate_etag</code> and <code>last_modified</code> are called as needed. Cowboy will only call them once and then cache the results for subsequent use.</p>

-<h1 class="lined-header"><span>REST handlers</span></h1>
-
-<p>REST is implemented in Cowboy as a protocol upgrade. Once upgraded, the request is handled as a state machine with many optional callbacks describing the resource and modifying the machine's behavior.</p>
-
-<p>The REST handler is the recommended way to handle requests.</p>
-
-<h2 id="initialization">Initialization</h2>
-
-<p>First, the <code>init/3</code> callback is called. This callback is common to all handlers. To use REST for the current request, this function must return an <code>upgrade</code> tuple.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-init({tcp, http}, Req, Opts) ->
-    {upgrade, protocol, cowboy_rest}.
-]]></script>
-
-<p>Cowboy will then switch to the REST protocol and start executing the state machine, starting from <code>rest_init/2</code> if it's defined, and ending with <code>rest_terminate/2</code> also if defined.</p>
-
-<h2 id="methods">Methods</h2>
-
-<p>The REST component has code for handling the following HTTP methods: HEAD, GET, POST, PATCH, PUT, DELETE and OPTIONS.</p>
-
-<p>Other methods can be accepted, however they have no specific callback defined for them at this time.</p>
-
-<h2 id="callbacks">Callbacks</h2>
-
-<p>All callbacks are optional. Some may become mandatory depending on what other defined callbacks return. The various flowcharts in the next chapter should be a useful to determine which callbacks you need.</p>
-
-<p>When the request starts being processed, Cowboy will call the <code>rest_init/2</code> function if it is defined, with the Req object and the handler options as arguments. This function must return <code>{ok, Req, State}</code> where <code>State</code> is the handler's state that all subsequent callbacks will receive.</p>
-
-<p>At the end of every request, the special callback <code>rest_terminate/2</code> will be called if it is defined. It cannot be used to send a reply, and must always return <code>ok</code>.</p>
-
-<p>All other callbacks are resource callbacks. They all take two arguments, the Req object and the State, and return a three-element tuple of the form <code>{Value, Req, State}</code>.</p>
-
-<p>The following table summarizes the callbacks and their default values. If the callback isn't defined, then the default value will be used. Please look at the flowcharts to find out the result of each return value.</p>
-
-<p>All callbacks can also return <code>{halt, Req, State}</code> to stop execution of the request, at which point <code>rest_terminate/2</code> will be called.</p>
-
-<p>In the following table, "skip" means the callback is entirely skipped if it is undefined, moving directly to the next step. Similarly, "none" means there is no default value for this callback.</p>
-
-<table class="table-bordered table-condensed table-striped">
-<thead>
-<tr><th>Callback name</th><th>Default value</th></tr>
-</thead>
-<tbody>
-<tr><td>allowed_methods</td><td><code>[<<"GET">>, <<"HEAD">>, <<"OPTIONS">>]</code></td></tr>

-</tbody>
-</table>
-
-<p>As you can see, Cowboy tries to move on with the request whenever possible by using well thought out default values.</p>
-
-<p>In addition to these, there can be any number of user-defined callbacks that are specified through <code>content_types_accepted/2</code> and <code>content_types_provided/2</code>. They can take any name, however it is recommended to use a separate prefix for the callbacks of each function. For example, <code>from_html</code> and <code>to_html</code> indicate in the first case that we're accepting a resource given as HTML, and in the second case that we send one as HTML.</p>
-
-<h2 id="meta_data">Meta data</h2>
-
-<p>Cowboy will set informative meta values at various points of the execution. You can retrieve them using <code>cowboy_req:meta/{2,3}</code>. The values are defined in the following table.</p>
-
-<table class="table-bordered table-condensed table-striped">
-<thead>
-<tr><th>Meta key</th><th>Details</th></tr>
-</thead>
-<tbody>
-<tr><td>media_type</td><td>The content-type negotiated for the response entity.</td></tr>
-<tr><td>language</td><td>The language negotiated for the response entity.</td></tr>
-<tr><td>charset</td><td>The charset negotiated for the response entity.</td></tr>
-</tbody>
-</table>
-
-<p>They can be used to send a proper body with the response to a request that used a method other than HEAD or GET.</p>
-
-<h2 id="response_headers">Response headers</h2>
-
-<p>Cowboy will set response headers automatically over the execution of the REST code. They are listed in the following table.</p>
-
-<table class="table-bordered table-condensed table-striped">
-<thead>
-<tr><th>Header name</th><th>Details</th></tr>
-</thead>
-<tbody>
-<tr><td>content-language</td><td>Language used in the response body</td></tr>
-<tr><td>content-type</td><td>Media type and charset of the response body</td></tr>
-<tr><td>etag</td><td>Etag of the resource</td></tr>
-<tr><td>expires</td><td>Expiration date of the resource</td></tr>
-<tr><td>last-modified</td><td>Last modification date for the resource</td></tr>
-<tr><td>location</td><td>Relative or absolute URI to the requested resource</td></tr>
-<tr><td>vary</td><td>List of headers that may change the representation of the resource</td></tr>

-
-<p>This chapter will attempt to define the concepts behind REST and explain what makes a service RESTful.</p>
-
-<p>REST is often confused with performing a distinct operation depending on the HTTP method, while using more than the GET and POST methods. That's highly misguided at best.</p>
-
-<p>We will first attempt to define REST and will look at what it means in the context of HTTP and the Web. For a more in-depth explanation of REST, you can read <a href="http://www.ics.uci.edu/~fielding/pubs/dissertation/top.htm">Roy T. Fielding's dissertation</a> as it does a great job explaining where it comes from and what it achieves.</p>
-
-<h2 id="rest_architecture">REST architecture</h2>
-
-<p>REST is a <em>client-server</em> architecture. The client and the server both have a different set of concerns. The server stores and/or manipulates information and makes it available to the user in an efficient manner. The client takes that information and displays it to the user and/or uses it to perform subsequent requests for information. This separation of concerns allows both the client and the server to evolve independently as it only requires that the interface stays the same.</p>
-
-<p>REST is <em>stateless</em>. That means the communication between the client and the server always contains all the information needed to perform the request. There is no session state in the server, it is kept entirely on the client's side. If access to a resource requires authentication, then the client needs to authenticate itself with every request.</p>
-
-<p>REST is <em>cacheable</em>. The client, the server and any intermediary components can all cache resources in order to improve performance.</p>
-
-<p>REST provides a <em>uniform interface</em> between components. This simplifies the architecture, as all components follow the same rules to speak to one another. It also makes it easier to understand the interactions between the different components of the system. A number of constraints are required to achieve this. They are covered in the rest of the chapter.</p>
-
-<p>REST is a <em>layered system</em>. Individual components cannot see beyond the immediate layer with which they are interacting. This means that a client connecting to an intermediate component, like a proxy, has no knowledge of what lies beyond. This allows components to be independent and thus easily replaceable or extendable.</p>
-
-<p>REST optionally provides <em>code on demand</em>. Code may be downloaded to extend client functionality. This is optional however because the client may not be able to download or run this code, and so a REST component cannot rely on it being executed.</p>
-
-<h2 id="resources_and_resource_identifiers">Resources and resource identifiers</h2>
-
-<p>A resource is an abstract concept. In a REST system, any information that can be named may be a resource. This includes documents, images, a collection of resources and any other information. Any information that can be the target of an hypertext link can be a resource.</p>
-
-<p>A resource is a conceptual mapping to a set of entities. The set of entities evolves over time; a resource doesn't. For example a resource can map to "users who have logged in this past month" and another to "all users". At some point in time they may map to the same set of entities, because all users logged in this past month. But they are still different resources. Similarly, if nobody logged in recently, then the first resource may map to the empty set. This resource exists regardless of the information it maps to.</p>
-
-<p>Resources are identified by uniform resource identifiers, also known as URIs. Sometimes internationalized resource identifiers, or IRIs, may also be used, but these can be directly translated into a URI.</p>
-
-<p>In practice we will identify two kinds of resources. Individual resources map to a set of one element, for example "user Joe". Collection of resources map to a set of 0 to N elements, for example "all users".</p>
-
-<h2 id="resource_representations">Resource representations</h2>
-
-<p>The representation of a resource is a sequence of bytes associated with metadata.</p>
-
-<p>The metadata comes as a list of key-value pairs, where the name corresponds to a standard that defines the value's structure and semantics. With HTTP, the metadata comes in the form of request or response headers. The headers' structure and semantics are well defined in the HTTP standard. Metadata includes representation metadata, resource metadata and control data.</p>
-
-<p>The representation metadata gives information about the representation, such as its media type, the date of last modification, or even a checksum.</p>
-
-<p>Resource metadata could be link to related resources or information about additional representations of the resource.</p>
-
-<p>Control data allows parameterizing the request or response. For example, we may only want the representation returned if it is more recent than the one we have in cache. Similarly, we may want to instruct the client about how it should cache the representation. This isn't restricted to caching. We may for example want to store a new representation of a resource only if it wasn't modified since we first retrieved it.</p>
-
-<p>The data format of a representation is also known as the media type. Some media types are intended for direct rendering to the user, while others are intended for automated processing. The media type is a key component of the REST architecture.</p>
-
-<h2 id="self-descriptive_messages">Self-descriptive messages</h2>
-
-<p>Messages must be self-descriptive. That means that the data format of a representation must always come with its media type (and similarly requesting a resource involves choosing the media type of the representation returned). If you are sending HTML, then you must say it is HTML by sending the media type with the representation. In HTTP this is done using the content-type header.</p>
-
-<p>The media type is often an IANA registered media type, like <code>text/html</code> or <code>image/png</code>, but does not need to be. Exactly two things are important for respecting this constraint: that the media type is well specified, and that the sender and recipient agree about what the media type refers to.</p>
-
-<p>This means that you can create your own media types, like <code>application/x-mine</code>, and that as long as you write the specifications for it and that both endpoints agree about it then the constraint is respected.</p>
-
-<h2 id="hypermedia_as_the_engine_of_application_state">Hypermedia as the engine of application state</h2>
-
-<p>The last constraint is generally where services that claim to be RESTful fail. Interactions with a server must be entirely driven by hypermedia. The client does not need any prior knowledge of the service in order to use it, other than an entry point and of course basic understanding of the media type of the representations, at the very least enough to find and identify hyperlinks and link relations.</p>
-
-<p>To give a simple example, if your service only works with the <code>application/json</code> media type then this constraint cannot be respected (as there are no concept of links in JSON) and thus your service isn't RESTful. This is the case for the majority of self-proclaimed REST services.</p>
-
-<p>On the other hand if you create a JSON based media type that has a concept of links and link relations, then your service might be RESTful.</p>
-
-<p>Respecting this constraint means that the entirety of the service becomes self-discoverable, not only the resources in it, but also the operations you can perform on it. This makes clients very thin as there is no need to implement anything specific to the service to operate on it.</p>

-<h1 class="lined-header"><span>Routing</span></h1>
-
-<p>Cowboy does nothing by default.</p>
-
-<p>To make Cowboy useful, you need to map URLs to Erlang modules that will handle the requests. This is called routing.</p>
-
-<p>When Cowboy receives a request, it tries to match the requested host and path to the resources given in the dispatch rules. If it matches, then the associated Erlang code will be executed.</p>
-
-<p>Routing rules are given per host. Cowboy will first match on the host, and then try to find a matching path.</p>
-
-<p>Routes need to be compiled before they can be used by Cowboy.</p>
-
-<h2 id="structure">Structure</h2>
-
-<p>The general structure for the routes is defined as follow.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-Routes = [Host1, Host2, ... HostN].
-]]></script>
-
-<p>Each host contains matching rules for the host along with optional constraints, and a list of routes for the path component.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-Host1 = {HostMatch, PathsList}.
-Host2 = {HostMatch, Constraints, PathsList}.
-]]></script>
-
-<p>The list of routes for the path component is defined similar to the list of hosts.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-PathsList = [Path1, Path2, ... PathN].
-]]></script>
-
-<p>Finally, each path contains matching rules for the path along with optional constraints, and gives us the handler module to be used along with options that will be given to it on initialization.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-Path1 = {PathMatch, Handler, Opts}.
-Path2 = {PathMatch, Constraints, Handler, Opts}.
-]]></script>
-
-<p>Continue reading to learn more about the match syntax and the optional constraints.</p>
-
-<h2 id="match_syntax">Match syntax</h2>
-
-<p>The match syntax is used to associate host names and paths with their respective handlers.</p>
-
-<p>The match syntax is the same for host and path with a few subtleties. Indeed, the segments separator is different, and the host is matched starting from the last segment going to the first. All examples will feature both host and path match rules and explain the differences when encountered.</p>
-
-<p>Excluding special values that we will explain at the end of this section, the simplest match value is a host or a path. It can be given as either a <code>string()</code> or a <code>binary()</code>.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-PathMatch1 = "/".
-PathMatch2 = "/path/to/resource".
-
-HostMatch1 = "cowboy.example.org".
-]]></script>
-
-<p>As you can see, all paths defined this way must start with a slash character. Note that these two paths are identical as far as routing is concerned.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-PathMatch2 = "/path/to/resource".
-PathMatch3 = "/path/to/resource/".
-]]></script>
-
-<p>Hosts with and without a trailing dot are equivalent for routing. Similarly, hosts with and without a leading dot are also equivalent.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-HostMatch1 = "cowboy.example.org".
-HostMatch2 = "cowboy.example.org.".
-HostMatch3 = ".cowboy.example.org".
-]]></script>
-
-<p>It is possible to extract segments of the host and path and to store the values in the <code>Req</code> object for later use. We call these kind of values bindings.</p>
-
-<p>The syntax for bindings is very simple. A segment that begins with the <code>:</code> character means that what follows until the end of the segment is the name of the binding in which the segment value will be stored.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-PathMatch = "/hats/:name/prices".
-HostMatch = ":subdomain.example.org".
-]]></script>
-
-<p>If these two end up matching when routing, you will end up with two bindings defined, <code>subdomain</code> and <code>name</code>, each containing the segment value where they were defined. For example, the URL <code>http://test.example.org/hats/wild_cowboy_legendary/prices</code> will result in having the value <code>test</code> bound to the name <code>subdomain</code> and the value <code>wild_cowboy_legendary</code> bound to the name <code>name</code>. They can later be retrieved using <code>cowboy_req:binding/{2,3}</code>. The binding name must be given as an atom.</p>
-
-<p>There is a special binding name you can use to mimic the underscore variable in Erlang. Any match against the <code>_</code> binding will succeed but the data will be discarded. This is especially useful for matching against many domain names in one go.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-HostMatch = "ninenines.:_".
-]]></script>
-
-<p>Similarly, it is possible to have optional segments. Anything between brackets is optional.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-PathMatch = "/hats/[page/:number]".
-HostMatch = "[www.]ninenines.eu".
-]]></script>
-
-<p>You can also have imbricated optional segments.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-PathMatch = "/hats/[page/[:number]]".
-]]></script>
-
-<p>You can retrieve the rest of the host or path using <code>[...]</code>. In the case of hosts it will match anything before, in the case of paths anything after the previously matched segments. It is a special case of optional segments, in that it can have zero, one or many segments. You can then find the segments using <code>cowboy_req:host_info/1</code> and <code>cowboy_req:path_info/1</code> respectively. They will be represented as a list of segments.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-PathMatch = "/hats/[...]".
-HostMatch = "[...]ninenines.eu".
-]]></script>
-
-<p>If a binding appears twice in the routing rules, then the match will succeed only if they share the same value. This copies the Erlang pattern matching behavior.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-PathMatch = "/hats/:name/:name".
-]]></script>
-
-<p>This is also true when an optional segment is present. In this case the two values must be identical only if the segment is available.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-PathMatch = "/hats/:name/[:name]".
-]]></script>
-
-<p>If a binding is defined in both the host and path, then they must also share the same value.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-PathMatch = "/:user/[...]".
-HostMatch = ":user.github.com".
-]]></script>
-
-<p>Finally, there are two special match values that can be used. The first is the atom <code>'_'</code> which will match any host or path.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-PathMatch = '_'.
-HostMatch = '_'.
-]]></script>
-
-<p>The second is the special host match <code>"*"</code> which will match the wildcard path, generally used alongside the <code>OPTIONS</code> method.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-HostMatch = "*".
-]]></script>
-
-<h2 id="constraints">Constraints</h2>
-
-<p>After the matching has completed, the resulting bindings can be tested against a set of constraints. Constraints are only tested when the binding is defined. They run in the order you defined them. The match will succeed only if they all succeed.</p>
-
-<p>They are always given as a two or three elements tuple, where the first element is the name of the binding, the second element is the constraint's name, and the optional third element is the constraint's arguments.</p>
-
-<p>The following constraints are currently defined:</p>
-
-<ul>
-<li>{Name, int}</li>
-<li>{Name, function, fun ((Value) -> true | {true, NewValue} | false)}</li>
-</ul>
-
-<p>The <code>int</code> constraint will check if the binding is a binary string representing an integer, and if it is, will convert the value to integer.</p>
-
-<p>The <code>function</code> constraint will pass the binding value to a user specified function that receives the binary value as its only argument and must return whether it fulfills the constraint, optionally modifying the value. The value thus returned can be of any type.</p>
-
-<p>Note that constraint functions SHOULD be pure and MUST NOT crash.</p>
-
-<h2 id="compilation">Compilation</h2>
-
-<p>The structure defined in this chapter needs to be compiled before it is passed to Cowboy. This allows Cowboy to efficiently lookup the correct handler to run instead of having to parse the routes repeatedly.</p>
-
-<p>This can be done with a simple call to <code>cowboy_router:compile/1</code>.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-Dispatch = cowboy_router:compile([
-    %% {HostMatch, list({PathMatch, Handler, Opts})}
-    {'_', [{'_', my_handler, []}]}
-]),
-%% Name, NbAcceptors, TransOpts, ProtoOpts
-cowboy:start_http(my_http_listener, 100,
-    [{port, 8080}],
-    [{env, [{dispatch, Dispatch}]}]
-).
-]]></script>
-
-<p>Note that this function will return <code>{error, badarg}</code> if the structure given is incorrect.</p>
-
-<h2 id="live_update">Live update</h2>
-
-<p>You can use the <code>cowboy:set_env/3</code> function for updating the dispatch list used by routing. This will apply to all new connections accepted by the listener.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-cowboy:set_env(my_http_listener, dispatch,
-    cowboy_router:compile(Dispatch)).
-]]></script>
-
-<p>Note that you need to compile the routes before updating.</p>

-<h1 class="lined-header"><span>Static handler</span></h1>
-
-<p>The static handler is a built-in REST handler for serving files. It is available as a convenience and provides a quick solution for serving files during development.</p>
-
-<p>For systems in production, consider using one of the many Content Distribution Network (CDN) available on the market, as they are the best solution for serving files. They are covered in the next chapter. If you decide against using a CDN solution, then please look at the chapter after that, as it explains how to efficiently serve static files on your own.</p>
-
-<p>The static handler can serve either one file or all files from a given directory. It can also send etag headers for client-side caching.</p>
-
-<p>To use the static file handler, simply add routes for it with the appropriate options.</p>
-
-<h2 id="serve_one_file">Serve one file</h2>
-
-<p>You can use the static handler to serve one specific file from an application's private directory. This is particularly useful to serve an <code>index.html</code> file when the client requests the <code>/</code> path, for example. The path configured is relative to the given application's private directory.</p>
-
-<p>The following rule will serve the file <code>static/index.html</code> from the application <code>my_app</code>'s priv directory whenever the path <code>/</code> is accessed.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{"/", cowboy_static, {priv_file, my_app, "static/index.html"}}
-]]></script>
-
-<p>You can also specify the absolute path to a file, or the path to the file relative to the current directory.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{"/", cowboy_static, {file, "/var/www/index.html"}}
-]]></script>
-
-<h2 id="serve_all_files_from_a_directory">Serve all files from a directory</h2>
-
-<p>You can also use the static handler to serve all files that can be found in the configured directory. The handler will use the <code>path_info</code> information to resolve the file location, which means that your route must end with a <code>[...]</code> pattern for it to work. All files are served, including the ones that may be found in subfolders.</p>
-
-<p>You can specify the directory relative to an application's private directory.</p>
-
-<p>The following rule will serve any file found in the application <code>my_app</code>'s priv directory inside the <code>static/assets</code> folder whenever the requested path begins with <code>/assets/</code>.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{"/assets/[...]", cowboy_static, {priv_dir, my_app, "static/assets"}}
-]]></script>
-
-<p>You can also specify the absolute path to the directory or set it relative to the current directory.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{"/assets/[...]", cowboy_static, {dir, "/var/www/assets"}}
-]]></script>
-
-<h2 id="customize_the_mimetype_detection">Customize the mimetype detection</h2>
-
-<p>By default, Cowboy will attempt to recognize the mimetype of your static files by looking at the extension.</p>
-
-<p>You can override the function that figures out the mimetype of the static files. It can be useful when Cowboy is missing a mimetype you need to handle, or when you want to reduce the list to make lookups faster. You can also give a hard-coded mimetype that will be used unconditionally.</p>
-
-<p>Cowboy comes with two functions built-in. The default function only handles common file types used when building Web applications. The other function is an extensive list of hundreds of mimetypes that should cover almost any need you may have. You can of course create your own function.</p>
-
-<p>To use the default function, you should not have to configure anything, as it is the default. If you insist, though, the following will do the job.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{"/assets/[...]", cowboy_static, {priv_dir, my_app, "static/assets",
-    [{mimetypes, cow_mimetypes, web}]}}
-]]></script>
-
-<p>As you can see, there is an optional field that may contain a list of less used options, like mimetypes or etag. All option types have this optional field.</p>
-
-<p>To use the function that will detect almost any mimetype, the following configuration will do.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{"/assets/[...]", cowboy_static, {priv_dir, my_app, "static/assets",
-    [{mimetypes, cow_mimetypes, all}]}}
-]]></script>
-
-<p>You probably noticed the pattern by now. The configuration expects a module and a function name, so you can use any of your own functions instead.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{"/assets/[...]", cowboy_static, {priv_dir, my_app, "static/assets",
-    [{mimetypes, Module, Function}]}}
-]]></script>
-
-<p>The function that performs the mimetype detection receives a single argument that is the path to the file on disk. It is recommended to return the mimetype in tuple form, although a binary string is also allowed (but will require extra processing). If the function can't figure out the mimetype, then it should return <code>{<<"application">>, <<"octet-stream">>, []}</code>.</p>
-
-<p>When the static handler fails to find the extension in the list, it will send the file as <code>application/octet-stream</code>. A browser receiving such file will attempt to download it directly to disk.</p>
-
-<p>Finally, the mimetype can be hard-coded for all files. This is especially useful in combination with the <code>file</code> and <code>priv_file</code> options as it avoids needless computation.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{"/", cowboy_static, {priv_file, my_app, "static/index.html",
-    [{mimetypes, {<<"text">>, <<"html">>, []}}]}}
-]]></script>
-
-<h2 id="generate_an_etag">Generate an etag</h2>
-
-<p>By default, the static handler will generate an etag header value based on the size and modified time. This solution can not be applied to all systems though. It would perform rather poorly over a cluster of nodes, for example, as the file metadata will vary from server to server, giving a different etag on each server.</p>
-
-<p>You can however change the way the etag is calculated.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{"/assets/[...]", cowboy_static, {priv_dir, my_app, "static/assets",
-    [{etag, Module, Function}]}}
-]]></script>
-
-<p>This function will receive three arguments: the path to the file on disk, the size of the file and the last modification time. In a distributed setup, you would typically use the file path to retrieve an etag value that is identical across all your servers.</p>
-
-<p>You can also completely disable etag handling.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{"/assets/[...]", cowboy_static, {priv_dir, my_app, "static/assets",
-    [{etag, false}]}}

-
-<p>Cowboy features many different handlers, each for different purposes. All handlers have a common entry point: the <code>init/3</code> function.</p>
-
-<p>The default handler type is the simple HTTP handler.</p>
-
-<p>To switch to a different protocol, you must perform a protocol upgrade. This is what is done for Websocket and REST and is explained in details in the respective chapters.</p>
-
-<p>You can also create your own protocol on top of Cowboy and use the protocol upgrade mechanism to switch to it.</p>
-
-<p>For example, if you create the <code>my_protocol</code> module implementing the <code>cowboy_sub_protocol</code> behavior, then you can upgrade to it by simply returning the module name from <code>init/3</code>.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-init(_, _, _Opts) ->
-    {upgrade, protocol, my_protocol}.
-]]></script>
-
-<p>The <code>cowboy_sub_protocol</code> behavior only requires one callback, <code>upgrade/4</code>. It receives the Req object, the middleware environment, and the handler and options for this request. This is the same module as the <code>init/3</code> function and the same options that were passed to it.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-upgrade(Req, Env, Handler, HandlerOpts) ->
-    %% ...
-]]></script>
-
-<p>This callback is expected to behave like a middleware. Please see the corresponding chapter for more information.</p>

-<h1 class="lined-header"><span>Handling Websocket connections</span></h1>
-
-<p>A special handler is required for handling Websocket connections. Websocket handlers allow you to initialize the connection, handle incoming frames from the socket, handle incoming Erlang messages and then clean up on termination.</p>
-
-<p>Websocket handlers essentially act as a bridge between the client and the Erlang system. They will typically do little more than socket communication and decoding/encoding of frames.</p>
-
-<h2 id="initialization">Initialization</h2>
-
-<p>First, the <code>init/3</code> callback is called. This callback is common to all handlers. To establish a Websocket connection, this function must return an <code>upgrade</code> tuple.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-init(_, Req, Opts) ->
-	{upgrade, protocol, cowboy_websocket}.
-]]></script>
-
-<p>It is also possible to return an update Req object and options using the longer form of this tuple.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-init(_Type, Req, Opts) ->
-	{upgrade, protocol, cowboy_websocket, Req, Opts}.
-]]></script>
-
-<p>Upon receiving this tuple, Cowboy will switch to the code that handles Websocket connections. It does not immediately perform the handshake however. First, it calls the <code>websocket_init/3</code> callback.</p>
-
-<p>This function must be used to initialize the state, and can also be used to register the process, start a timer, etc. As long as the function returns an <code>ok</code> tuple, then Cowboy performs the Websocket handshake.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-websocket_init(_Type, Req, _Opts) ->
-    {ok, Req, #state{}}.
-]]></script>
-
-<p>A <code>shutdown</code> tuple can be returned to refuse to perform the handshake. When doing so, Cowboy will send a <code>400 Bad Request</code> response to the client and close the connection.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-websocket_init(_Type, Req, _Opts) ->
-	{shutdown, Req}.
-]]></script>
-
-<p>It is also possible to perform a <code>cowboy_req:reply/{2,3,4}</code> before returning a <code>shutdown</code> tuple, allowing you to override the response sent back to the client.</p>
-
-<p>Note that browser support for handling Websocket connection failures may vary.</p>
-
-<p>If the sec-websocket-protocol header was sent with the request for establishing a Websocket connection, then the Websocket handler <em>must</em> select one of these subprotocol and send it back to the client, otherwise the client might decide to close the connection, assuming no correct subprotocol was found.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-websocket_init(_Type, Req, _Opts) ->
-	case cowboy_req:parse_header(<<"sec-websocket-protocol">>, Req) of
-		{ok, undefined, Req2} ->
-			{ok, Req, #state{}};
-		{ok, Subprotocols, Req2} ->
-			case lists:keymember(<<"mychat2">>, 1, Subprotocols) of
-				true ->
-					Req3 = cowboy_req:set_resp_header(<<"sec-websocket-protocol">>,
-						<<"mychat2">>, Req2),
-					{ok, Req3, #state{}};
-				false ->
-					{shutdown, Req2}
-			end
-	end.
-]]></script>
-
-<p>It is not recommended to wait too long inside the <code>websocket_init/3</code> function. Any extra initialization may be done after returning by sending yourself a message before doing anything. Any message sent to <code>self()</code> from <code>websocket_init/3</code> is guaranteed to arrive before any frames from the client.</p>
-
-<p>It is also very easy to ensure that this message arrives before any message from other processes by sending it before registering or enabling timers.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-websocket_init(_Type, Req, _Opts) ->
-	self() ! post_init,
-	%% Register process here...
-	{ok, Req, #state{}}.
-
-websocket_info(post_init, Req, State) ->
-	%% Perform post_init initialization here...
-	{ok, Req, State}.
-]]></script>
-
-<h2 id="handling_frames_from_the_client">Handling frames from the client</h2>
-
-<p>Cowboy will call <code>websocket_handle/3</code> whenever a text, binary, ping or pong frame arrives from the client. Note that in the case of ping and pong frames, no action is expected as Cowboy automatically replies to ping frames.</p>
-
-<p>The handler can decide to send frames to the socket, shutdown or just continue without sending anything.</p>
-
-<p>The following snippet echoes back any text frame received and ignores all others.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-websocket_handle(Frame = {text, _}, Req, State) ->
-	{reply, Frame, Req, State};
-websocket_handle(_Frame, Req, State) ->
-	{ok, Req, State}.
-]]></script>
-
-<h2 id="handling_erlang_messages">Handling Erlang messages</h2>
-
-<p>Cowboy will call <code>websocket_info/3</code> whenever an Erlang message arrives.</p>
-
-<p>The handler can decide to send frames to the socket, shutdown or just continue without sending anything.</p>
-
-<p>The following snippet forwards any <code>log</code> message to the socket and ignores all others.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-websocket_info({log, Text}, Req, State) ->
-	{reply, {text, Text}, Req, State};
-websocket_info(_Info, Req, State) ->
-	{ok, Req, State}.
-]]></script>
-
-<h2 id="sending_frames_to_the_socket">Sending frames to the socket</h2>
-
-<p>Cowboy allows sending either a single frame or a list of frames to the socket. Any frame can be sent: text, binary, ping, pong or close frames.</p>
-
-<p>The following example sends three frames using a single <code>reply</code> tuple.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-websocket_info(hello_world, Req, State) ->
-	{reply, [
-		{text, "Hello"},
-		{text, <<"world!">>},
-		{binary, <<0:8000>>}
-	], Req, State};
-%% More websocket_info/3 clauses here...
-]]></script>
-
-<p>Note that the payload for text and binary frames is of type <code>iodata()</code>, meaning it can be either a <code>binary()</code> or an <code>iolist()</code>.</p>
-
-<p>Sending a <code>close</code> frame will immediately initiate the closing of the Websocket connection. Be aware that any additional frames sent by the client or any Erlang messages waiting to be received will not be processed. Also note that when replying a list of frames that includes close, any frame found after the close frame will not be sent.</p>
-
-<h2 id="ping_and_timeout">Ping and timeout</h2>
-
-<p>The biggest performance improvement you can do when dealing with a huge number of Websocket connections is to reduce the number of timers that are started on the server. A common use of timers when dealing with connections is for sending a ping every once in a while. This should be done exclusively on the client side. Indeed, a server handling one million Websocket connections will perform a lot better when it doesn't have to handle one million extra timers too!</p>
-
-<p>Cowboy will automatically respond to ping frames sent by the client. It will still forward the frame to the handler for informative purpose, but no further action is required.</p>
-
-<p>Cowboy can be configured to automatically close the Websocket connection when no data arrives on the socket. It is highly recommended to configure a timeout for it, as otherwise you may end up with zombie "half-connected" sockets that may leave the process alive forever.</p>
-
-<p>A good timeout value is 60 seconds.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-websocket_init(_Type, Req, _Opts) ->
-	{ok, Req, #state{}, 60000}.
-]]></script>
-
-<p>This value cannot be changed once it is set. It defaults to <code>infinity</code>.</p>
-
-<h2 id="hibernate">Hibernate</h2>
-
-<p>Most tuples returned from handler callbacks can include an extra value <code>hibernate</code>. After doing any necessary operations following the return of the callback, Cowboy will hibernate the process.</p>
-
-<p>It is highly recommended to hibernate processes that do not handle much traffic. It is a good idea to hibernate all connections by default and investigate only when you start noticing increased CPU usage.</p>
-
-<h2 id="supporting_older_browsers">Supporting older browsers</h2>
-
-<p>Unfortunately Websocket is a relatively recent technology, which means that not all browsers support it. A library like <a href="https://github.com/extend/bullet">Bullet</a> can be used to emulate Websocket connections on older browsers.</p>

-<h1 class="lined-header"><span>The Websocket protocol</span></h1>
-
-<p>This chapter explains what Websocket is and why it is a vital component of soft realtime Web applications.</p>
-
-<h2 id="description">Description</h2>
-
-<p>Websocket is an extension to HTTP that emulates plain TCP connections between the client, typically a Web browser, and the server. It uses the HTTP Upgrade mechanism to establish the connection.</p>
-
-<p>Websocket connections are asynchronous, unlike HTTP. This means that not only can the client send frames to the server at any time, but the server can also send frames to the client without the client initiating anything other than the Websocket connection itself. This allows the server to push data to the client directly.</p>
-
-<p>Websocket is an IETF standard. Cowboy supports the standard and all drafts that were previously implemented by browsers, excluding the initial flawed draft sometimes known as "version 0".</p>
-
-<h2 id="implementation">Implementation</h2>
-
-<p>Cowboy implements Websocket as a protocol upgrade. Once the upgrade is performed from the <code>init/3</code> callback, Cowboy switches to Websocket. Please consult the next chapter for more information on initiating and handling Websocket connections.</p>
-
-<p>The implementation of Websocket in Cowboy is validated using the Autobahn test suite, which is an extensive suite of tests covering all aspects of the protocol. Cowboy passes the suite with 100% success, including all optional tests.</p>
-
-<p>Cowboy's Websocket implementation also includes the x-webkit-deflate-frame compression draft which is being used by some browsers to reduce the size of data being transmitted. Cowboy will automatically use compression as long as the <code>compress</code> protocol option is set when starting the listener.</p>

-<p>Cowboy is a small, fast and modular HTTP server written in Erlang.</p>
-<h2 id="goals">Goals</h2>
-<p>Cowboy aims to provide a <strong>complete</strong> HTTP stack in a <strong>small</strong> code base. It is optimized for <strong>low latency</strong> and <strong>low memory usage</strong>, in part because it uses <strong>binary strings</strong>.</p>
-<p>Cowboy provides <strong>routing</strong> capabilities, selectively dispatching requests to handlers written in Erlang.</p>
-<p>Because it uses Ranch for managing connections, Cowboy can easily be <strong>embedded</strong> in any other application.</p>
-<p>No parameterized module. No process dictionary. <strong>Clean</strong> Erlang code.</p>
-<h2 id="sponsors">Sponsors</h2>
-<p>The SPDY implementation was sponsored by <a href="http://www.leofs.org">LeoFS Cloud Storage</a>.</p>
-<p>The project is currently sponsored by <a href="https://kato.im">Kato.im</a>.</p>

-
-<p>The <code>cowboy</code> application uses the Erlang applications <code>ranch</code> for listening and accepting TCP connections, <code>crypto</code> for establishing Websocket connections, and <code>cowlib</code> for parsing and building messages for Web protocols. These dependencies must be loaded for the <code>cowboy</code> application to work. In an embedded environment this means that they need to be started with the <code>application:start/{1,2}</code> function before the <code>cowboy</code> application is started.</p>
-
-<p>The <code>cowboy</code> application also uses the Erlang applications <code>asn1</code>, <code>public_key</code> and <code>ssl</code> when listening for HTTPS connections. These are started automatically if they weren't before.</p>
-
-<h2 id="environment">Environment</h2>
-
-<p>The <code>cowboy</code> application does not define any application environment configuration parameters.</p>

-
-<p>The <code>cowboy_loop_handler</code> behaviour defines the interface used by HTTP handlers that do not send a response directly, instead requiring a receive loop to process Erlang messages.</p>
-
-<p>This interface is best fit for long-polling types of requests.</p>
-
-<p>The <code>init/3</code> callback will always be called, followed by zero or more calls to <code>info/3</code>. The <code>terminate/3</code> callback will always be called last.</p>

-<h3 id="init">init({TransportName, ProtocolName}, Req, Opts) -> {loop, Req, State} | {loop, Req, State, hibernate} | {loop, Req, State, Timeout} | {loop, Req, State, Timeout, hibernate} | {shutdown, Req, State}</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>TransportName = tcp | ssl | atom()</li>
-<li>ProtocolName = http | atom()</li>
-<li>Req = cowboy_req:req()</li>
-<li>Opts = any()</li>
-<li>State = any()</li>
-<li>Timeout = timeout()</li>
-</ul>
-
-<p>Initialize the state for this request.</p>
-
-<p>This callback will typically be used to register this process to an event manager or a message queue in order to receive the messages the handler wants to process.</p>
-
-<p>The receive loop will run for a duration of up to <code>Timeout</code> milliseconds after it last received data from the socket, at which point it will stop and send a <code>204 No Content</code> reply. By default this value is set to <code>infinity</code>. It is recommended to either set this value or ensure by any other mechanism that the handler will be closed after a certain period of inactivity.</p>
-
-<p>The <code>hibernate</code> option will hibernate the process until it starts receiving messages.</p>
-
-<p>The <code>shutdown</code> return value can be used to skip the receive loop entirely.</p>
-
-<h3 id="info">info(Info, Req, State) -> {ok, Req, State} | {loop, Req, State} | {loop, Req, State, hibernate}</h3>
-
-<p>Types:</p>
-

-<li>Info = any()</li>
-<li>Req = cowboy_req:req()</li>
-<li>State = any()</li>
-</ul>
-
-<p>Handle the Erlang message received.</p>
-
-<p>This function will be called every time an Erlang message has been received. The message can be any Erlang term.</p>
-
-<p>The <code>ok</code> return value can be used to stop the receive loop, typically because a response has been sent.</p>
-
-<p>The <code>hibernate</code> option will hibernate the process until it receives another message.</p>
-
-<h3 id="terminate">terminate(Reason, Req, State) -> ok</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>Reason = {normal, shutdown} | {normal, timeout} | {error, closed} | {error, overflow} | {error, atom()}</li>
-<li>Req = cowboy_req:req()</li>
-<li>State = any()</li>
-</ul>
-
-<p>Perform any necessary cleanup of the state.</p>
-
-<p>This callback will typically unregister from any event manager or message queue it registered to in <code>init/3</code>.</p>
-
-<p>This callback should release any resource currently in use, clear any active timer and reset the process to its original state, as it might be reused for future requests sent on the same connection.</p>

-
-<p>The <code>cowboy_middleware</code> behaviour defines the interface used by Cowboy middleware modules.</p>
-
-<p>Middlewares process the request sequentially in the order they are configured.</p>
-
-<h2 id="types">Types</h2>
-
-<h3 id="env">env() = [{atom(), any()}]</h3>
-
-<p>The environment variable.</p>
-
-<p>One is created for every request. It is passed to each middleware module executed and subsequently returned, optionally with its contents modified.</p>
-
-<h2 id="callbacks">Callbacks</h2>
-
-<h3 id="execute">execute(Req, Env) -> {ok, Req, Env} | {suspend, Module, Function, Args} | {halt, Req} | {error, StatusCode, Req}</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>Req = cowboy_req:req()</li>
-<li>Env = env()</li>
-<li>Module = module()</li>
-<li>Function = atom()</li>
-<li>Args = [any()]</li>
-<li>StatusCode = cowboy:http_status()</li>
-</ul>
-
-<p>Execute the middleware.</p>
-
-<p>The <code>ok</code> return value indicates that everything went well and that Cowboy should continue processing the request. A response may or may not have been sent.</p>
-
-<p>The <code>suspend</code> return value will hibernate the process until an Erlang message is received. Note that when resuming, any previous stacktrace information will be gone.</p>
-
-<p>The <code>halt</code> return value stops Cowboy from doing any further processing of the request, even if there are middlewares that haven't been executed yet. The connection may be left open to receive more requests from the client.</p>
-
-<p>The <code>error</code> return value sends an error response identified by the <code>StatusCode</code> and then proceeds to terminate the connection. Middlewares that haven't been executed yet will not be called.</p>

-
-<p>The <code>cowboy_req</code> module provides functions to access, manipulate and respond to requests.</p>
-
-<p>The functions in this module follow patterns for their return types, based on the kind of function.</p>
-
-<ul>
-<li>access: <code>{Value, Req}</code></li>
-<li>action: <code>{Result, Req} | {Result, Value, Req} | {error, atom()}</code></li>
-<li>modification: <code>Req</code></li>
-<li>question: <code>boolean()</code></li>
-</ul>
-
-<p>The only exception is the <code>chunk/2</code> function which may return <code>ok</code>.</p>
-
-<p>Whenever <code>Req</code> is returned, you must use this returned value and ignore any previous you may have had. This value contains various state informations which are necessary for Cowboy to do some lazy evaluation or cache results where appropriate.</p>
-
-<p>All functions which perform an action should only be called once. This includes reading the request body or replying. Cowboy will generally throw an error on the second call.</p>
-
-<p>It is highly discouraged to pass the Req object to another process. Doing so and calling <code>cowboy_req</code> functions from it leads to undefined behavior.</p>
-
-<h2 id="types">Types</h2>
-
-<h3 id="body_opts">body_opts() = [{continue, boolean()} | {length, non_neg_integer()} | {read_length, non_neg_integer()} | {read_timeout, timeout()} | {transfer_decode, transfer_decode_fun(), any()} | {content_decode, content_decode_fun()}]</h3>

-
-<p>The Req object.</p>
-
-<p>All functions in this module receive a <code>Req</code> as argument, and most of them return a new object labelled <code>Req2</code> in the function descriptions below.</p>

-
-<p>Types:</p>
-
-<ul>
-<li>HostURL = binary() | undefined</li>
-</ul>
-
-<p>Return the requested URL excluding the path component.</p>
-
-<p>This function will always return <code>undefined</code> until the <code>cowboy_router</code> middleware has been executed. This includes the <code>onrequest</code> hook.</p>
-
-<h3 id="meta">meta(Name, Req) -> meta(Name, Req, undefined)</h3>
-

-
-<p>Parse the given header.</p>
-
-<p>While header names are case insensitive, this function expects the name to be a lowercase binary.</p>
-
-<p>The <code>parse_header/2</code> function will call <code>parser_header/3</code> with a different default value depending on the header being parsed. The following table summarizes the default values used.</p>
-

-</table>
-
-<p>Types for the above table:</p>
-
-<ul>
-<li>Type = SubType = Charset = Encoding = LanguageTag = binary()</li>
-<li>AuthType = Expect = OpaqueTag = Unit = binary()</li>
-<li>Params = ContentTypeParams = [{binary(), binary()}]</li>

-<li>Credentials - see below</li>
-<li>Range = {non_neg_integer(), non_neg_integer() | infinity} | neg_integer()</li>
-</ul>
-
-<p>The cookie names and values, the values of the sec-websocket-protocol and x-forwarded-for headers, the values in <code>AcceptExt</code> and <code>Params</code>, the authorization <code>Credentials</code>, the <code>ExpectValue</code> and <code>OpaqueTag</code> are case sensitive. All values in <code>ContentTypeParams</code> are case sensitive except the value of the charset parameter, which is case insensitive. All other values are case insensitive and will be returned as lowercase.</p>
-
-<p>The headers accept, accept-encoding and cookie headers can return an empty list. Others will return <code>{error, badarg}</code> if the header value is empty.</p>
-
-<p>The authorization header parsing code currently only supports basic HTTP authentication. The <code>Credentials</code> type is thus <code>{Username, Password}</code> with <code>Username</code> and <code>Password</code> being <code>binary()</code>.</p>
-
-<p>The range header value <code>Range</code> can take three forms:</p>
-
-<ul>
-<li><code>{From, To}</code>: from <code>From</code> to <code>To</code> units</li>
-<li><code>{From, infinity}</code>: everything after <code>From</code> units</li>
-<li><code>-Final</code>: the final <code>Final</code> units</li>
-</ul>
-
-<p>An <code>undefined</code> tuple will be returned if Cowboy doesn't know how to parse the requested header.</p>
-
-<h3 id="path">path(Req) -> {Path, Req2}</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>Path = binary()</li>

-
-<p>Types:</p>
-
-<ul>
-<li>Port = inet:port_number()</li>
-</ul>
-
-<p>Return the request's port.</p>
-
-<p>The port returned by this function is obtained by parsing the host header. It may be different than the actual port the client used to connect to the Cowboy server.</p>
-
-<h3 id="qs">qs(Req) -> {QueryString, Req2}</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>QueryString = binary()</li>
-</ul>
-
-<p>Return the request's query string.</p>
-
-<h3 id="qs_val">qs_val(Name, Req) -> qs_val(Name, Req, undefined)</h3>

-<li>Default = any()</li>
-<li>Value = binary() | true</li>
-</ul>
-
-<p>Return a value from the request's query string.</p>
-
-<p>The value <code>true</code> will be returned when the name was found in the query string without an associated value.</p>
-
-<h3 id="qs_vals">qs_vals(Req) -> {[{Name, Value}], Req2}</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>Name = binary()</li>
-<li>Value = binary() | true</li>
-</ul>
-
-<p>Return the request's query string as a list of tuples.</p>
-

-
-<h3 id="set_meta">set_meta(Name, Value, Req) -> Req2</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>Name = atom()</li>
-<li>Value = any()</li>
-</ul>
-
-<p>Set metadata about the request.</p>
-
-<p>An existing value will be overwritten.</p>
-
-<h3 id="url">url(Req) -> {URL, Req2}</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>URL = binary() | undefined</li>
-</ul>
-
-<p>Return the requested URL.</p>
-
-<p>This function will always return <code>undefined</code> until the <code>cowboy_router</code> middleware has been executed. This includes the <code>onrequest</code> hook.</p>
-
-<h3 id="version">version(Req) -> {Version, Req2}</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>Version = cowboy:http_version()</li>
-</ul>
-
-<p>Return the HTTP version used for this request.</p>
-
-<h2 id="request_body_related_exports">Request body related exports</h2>
-
-<h3 id="body">body(Req) -> body(Req, [])</h3>
-
-<h3 id="body">body(Req, Opts) -> {ok, Data, Req2} | {more, Data, Req2} | {error, Reason}</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>Opts = [body_opt()]</li>
-<li>Data = binary()</li>
-<li>Reason = atom()</li>
-</ul>
-
-<p>Read the request body.</p>
-
-<p>This function will read a chunk of the request body. If there is more data to be read after this function call, then a <code>more</code> tuple is returned. Otherwise an <code>ok</code> tuple is returned.</p>
-
-<p>Cowboy will automatically send a <code>100 Continue</code> reply if required. If this behavior is not desirable, it can be disabled by setting the <code>continue</code> option to <code>false</code>.</p>
-
-<p>Cowboy will by default attempt to read up to 8MB of the body, but in chunks of 1MB. It will use a timeout of 15s per chunk. All these values can be changed using the <code>length</code>, <code>read_length</code> and <code>read_timeout</code> options respectively. Note that the size of the data may not be the same as requested as the decoding functions may grow or shrink it, and Cowboy makes not attempt at returning an exact amount.</p>
-
-<p>Cowboy will properly handle chunked transfer-encoding by default. If any other transfer-encoding or content-encoding has been used for the request, custom decoding functions can be used. The <code>content_decode</code> and <code>transfer_decode</code> options allow setting the decode functions manually.</p>
-
-<p>After the body has been streamed fully, Cowboy will remove the transfer-encoding header from the Req object, and add the content-length header if it wasn't already there.</p>
-
-<p>This function can only be called once. Cowboy will not cache the result of this call.</p>
-
-<h3 id="body_length">body_length(Req) -> {Length, Req2}</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>Length = non_neg_integer() | undefined</li>
-</ul>
-
-<p>Return the length of the request body.</p>
-
-<p>The length will only be returned if the request does not use any transfer-encoding and if the content-length header is present.</p>
-
-<h3 id="body_qs">body_qs(Req) -> body_qs(Req, [{length, 64000}, {read_length, 64000}, {read_timeout, 5000}])</h3>
-
-<h3 id="body_qs">body_qs(Req, Opts) -> {ok, [{Name, Value}], Req2} | {badlength, Req2} | {error, Reason}</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>Opts = [body_opt()]</li>
-<li>Name = binary()</li>
-<li>Value = binary() | true</li>
-<li>Reason = chunked | badlength | atom()</li>
-</ul>
-
-<p>Return the request body as a list of tuples.</p>
-
-<p>This function will parse the body assuming the content-type application/x-www-form-urlencoded, commonly used for the query string.</p>
-
-<p>This function calls <code>body/2</code> for reading the body, with the same options it received. By default it will attempt to read a body of 64KB in one chunk, with a timeout of 5s. If the body is larger then a <code>badlength</code> tuple is returned.</p>
-
-<p>This function can only be called once. Cowboy will not cache the result of this call.</p>
-
-<h3 id="has_body">has_body(Req) -> boolean()</h3>
-
-<p>Return whether the request has a body.</p>
-
-<h3 id="part">part(Req) -> part(Req, [{length, 64000}, {read_length, 64000}, {read_timeout, 5000}])</h3>
-
-<h3 id="part">part(Req, Opts) -> {ok, Headers, Req2} | {done, Req2}</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>Opts = [body_opt()]</li>
-<li>Headers = cow_multipart:headers()</li>
-</ul>
-
-<p>Read the headers for the next part of the multipart message.</p>
-
-<p>Cowboy will skip any data remaining until the beginning of the next part. This includes the preamble to the multipart message but also the body of a previous part if it hasn't been read. Both are skipped automatically when calling this function.</p>
-
-<p>The headers returned are MIME headers, NOT HTTP headers. They can be parsed using the functions from the <code>cow_multipart</code> module. In addition, the <code>cow_multipart:form_data/1</code> function can be used to quickly figure out <code>multipart/form-data</code> messages. It takes the list of headers and returns whether this part is a simple form field or a file being uploaded.</p>
-
-<p>Note that once a part has been read, or skipped, it cannot be read again.</p>
-
-<p>This function calls <code>body/2</code> for reading the body, with the same options it received. By default it will only read chunks of 64KB with a timeout of 5s. This is tailored for reading part headers, not for skipping the previous part's body. You might want to consider skipping large parts manually.</p>

-<h3 id="part_body">part_body(Req) -> part_body(Req, [])</h3>
-
-<h3 id="part_body">part_body(Req, Opts) -> {ok, Data, Req2} | {more, Data, Req2}</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>Opts = [body_opt()]</li>
-<li>Data = binary()</li>
-</ul>
-
-<p>Read the body of the current part of the multipart message.</p>
-
-<p>This function calls <code>body/2</code> for reading the body, with the same options it received. It uses the same defaults.</p>
-
-<p>If there are more data to be read from the socket for this part, the function will return what it could read inside a <code>more</code> tuple. Otherwise, it will return an <code>ok</code> tuple.</p>
-
-<p>Calling this function again after receiving a <code>more</code> tuple will return another chunk of body. The last chunk will be returned inside an <code>ok</code> tuple.</p>
-
-<p>Note that once the body has been read, fully or partially, it cannot be read again.</p>
-
-<h2 id="response_related_exports">Response related exports</h2>
-
-<h3 id="chunk">chunk(Data, Req) -> ok | {error, Reason}</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>Data = iodata()</li>
-<li>Reason = atom()</li>
-</ul>
-
-<p>Send a chunk of data.</p>
-
-<p>This function should be called as many times as needed to send data chunks after calling <code>chunked_reply/{2,3}</code>.</p>
-
-<p>When the method is HEAD, no data will actually be sent.</p>
-
-<p>If the request uses HTTP/1.0, the data is sent directly without wrapping it in an HTTP/1.1 chunk, providing compatibility with older clients.</p>
-
-<h3 id="chunked_reply">chunked_reply(StatusCode, Req) -> chunked_reply(StatusCode, [], Req)</h3>
-
-<h3 id="chunked_reply">chunked_reply(StatusCode, Headers, Req) -> {ok, Req2}</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>StatusCode = cowboy:http_status()</li>
-<li>Headers = cowboy:http_headers()</li>
-</ul>
-
-<p>Send a response using chunked transfer-encoding.</p>
-
-<p>This function effectively sends the response status line and headers to the client.</p>
-
-<p>This function will not send any body set previously. After this call the handler must use the <code>chunk/2</code> function repeatedly to send the body in as many chunks as needed.</p>
-
-<p>If the request uses HTTP/1.0, the data is sent directly without wrapping it in an HTTP/1.1 chunk, providing compatibility with older clients.</p>
-
-<p>This function can only be called once, with the exception of overriding the response in the <code>onresponse</code> hook.</p>
-
-<h3 id="continue">continue(Req) -> ok | {error, Reason}</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>Reason = atom()</li>
-</ul>
-
-<p>Send a 100 Continue intermediate reply.</p>
-
-<p>This reply is required before the client starts sending the body when the request contains the <code>expect</code> header with the <code>100-continue</code> value.</p>
-
-<p>Cowboy will send this automatically when required. However you may want to do it manually by disabling this behavior with the <code>continue</code> body option and then calling this function.</p>
-
-<h3 id="delete_resp_header">delete_resp_header(Name, Req) -> Req2</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>Name = binary()</li>
-</ul>
-
-<p>Delete the given response header.</p>
-
-<p>While header names are case insensitive, this function expects the name to be a lowercase binary.</p>
-
-<h3 id="has_resp_body">has_resp_body(Req) -> boolean()</h3>
-
-<p>Return whether a response body has been set.</p>
-
-<p>This function will return false if a response body has been set with a length of 0.</p>
-
-<h3 id="has_resp_header">has_resp_header(Name, Req) -> boolean()</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>Name = binary()</li>
-</ul>
-
-<p>Return whether the given response header has been set.</p>
-
-<p>While header names are case insensitive, this function expects the name to be a lowercase binary.</p>
-
-<h3 id="reply">reply(StatusCode, Req) -> reply(StatusCode, [], Req)</h3>
-
-<h3 id="reply">reply(StatusCode, Headers, Req) - see below</h3>
-
-<h3 id="reply">reply(StatusCode, Headers, Body, Req) -> {ok, Req2}</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>StatusCode = cowboy:http_status()</li>
-<li>Headers = cowboy:http_headers()</li>
-<li>Body = iodata()</li>
-</ul>
-
-<p>Send a response.</p>
-
-<p>This function effectively sends the response status line, headers and body to the client, in a single send function call.</p>
-
-<p>The <code>reply/2</code> and <code>reply/3</code> functions will send the body set previously, if any. The <code>reply/4</code> function overrides any body set previously and sends <code>Body</code> instead.</p>
-
-<p>If a body function was set, and <code>reply/2</code> or <code>reply/3</code> was used, it will be called before returning.</p>
-
-<p>No more data can be sent to the client after this function returns.</p>
-
-<p>This function can only be called once, with the exception of overriding the response in the <code>onresponse</code> hook.</p>
-
-<h3 id="set_resp_body">set_resp_body(Body, Req) -> Req2</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>Body = iodata()</li>
-</ul>
-
-<p>Set a response body.</p>
-
-<p>This body will not be sent if <code>chunked_reply/{2,3}</code> or <code>reply/4</code> is used, as they override it.</p>
-
-<h3 id="set_resp_body_fun">set_resp_body_fun(Fun, Req) -> Req2</h3>
-
-<h3 id="set_resp_body_fun">set_resp_body_fun(Length, Fun, Req) -> Req2</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>Fun = fun((Socket, Transport) -> ok)</li>
-<li>Socket = inet:socket()</li>
-<li>Transport = module()</li>
-<li>Length = non_neg_integer()</li>
-</ul>
-
-<p>Set a fun for sending the response body.</p>
-
-<p>If a <code>Length</code> is provided, it will be sent in the content-length header in the response. It is recommended to set the length if it can be known in advance. Otherwise, the transfer-encoding header will be set to identity.</p>
-
-<p>This function will only be called if the response is sent using the <code>reply/2</code> or <code>reply/3</code> function.</p>
-
-<p>The fun will receive the Ranch <code>Socket</code> and <code>Transport</code> as arguments. Only send and sendfile operations are supported.</p>
-
-<h3 id="set_resp_body_fun">set_resp_body_fun(chunked, Fun, Req) -> Req2</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>Fun = fun((ChunkFun) -> ok)</li>
-<li>ChunkFun = fun((iodata()) -> ok | {error, atom()})</li>
-</ul>
-
-<p>Set a fun for sending the response body using chunked transfer-encoding.</p>
-
-<p>This function will only be called if the response is sent using the <code>reply/2</code> or <code>reply/3</code> function.</p>
-
-<p>The fun will receive another fun as argument. This fun is to be used to send chunks in a similar way to the <code>chunk/2</code> function, except the fun only takes one argument, the data to be sent in the chunk.</p>
-
-<h3 id="set_resp_cookie">set_resp_cookie(Name, Value, Opts, Req) -> Req2</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>Name = iodata()</li>
-<li>Value = iodata()</li>
-<li>Opts = cookie_opts()</li>
-</ul>
-
-<p>Set a cookie in the response.</p>
-
-<p>Cookie names are case sensitive.</p>
-
-<h3 id="set_resp_header">set_resp_header(Name, Value, Req) -> Req2</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>Name = binary()</li>
-<li>Value = iodata()</li>
-</ul>
-
-<p>Set a response header.</p>
-
-<p>You should use <code>set_resp_cookie/4</code> instead of this function to set cookies.</p>
-
-<h2 id="misc._exports">Misc. exports</h2>
-
-<h3 id="compact">compact(Req) -> Req2</h3>
-
-<p>Remove any non-essential data from the Req object.</p>
-
-<p>Long-lived connections usually only need to manipulate the Req object at initialization. Compacting allows saving up memory by discarding extraneous information.</p>

-<p>The <code>cowboy_rest</code> module implements REST semantics on top of the HTTP protocol.</p>
-
-<p>This module cannot be described as a behaviour due to most of the callbacks it defines being optional. It has the same semantics as a behaviour otherwise.</p>
-
-<p>The only mandatory callback is <code>init/3</code>, needed to perform the protocol upgrade.</p>
-

-
-<p>Negotiated media-type.</p>
-
-<p>The media-type is the content-type, excluding the charset.</p>
-
-<p>This value is always defined after the call to <code>content_types_provided/2</code>.</p>
-
-<h2 id="callbacks">Callbacks</h2>
-
-<h3 id="init">init({TransportName, ProtocolName}, Req, Opts) -> {upgrade, protocol, cowboy_rest} | {upgrade, protocol, cowboy_rest, Req, Opts}</h3>

-
-<ul>
-<li>TransportName = tcp | ssl | atom()</li>
-<li>ProtocolName = http | atom()</li>
-<li>Req = cowboy_req:req()</li>
-<li>Opts = any()</li>
-</ul>
-
-<p>Upgrade the protocol to <code>cowboy_rest</code>.</p>
-
-<p>This is the only mandatory callback.</p>
-
-<h3 id="rest_init">rest_init(Req, Opts) -> {ok, Req, State}</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>Req = cowboy_req:req()</li>
-<li>Opts = any()</li>
-<li>State = any()</li>
-</ul>
-
-<p>Initialize the state for this request.</p>

-
-<p>Types:</p>
-
-<ul>
-<li>Req = cowboy_req:req()</li>
-<li>State = any()</li>
-</ul>
-
-<p>Perform any necessary cleanup of the state.</p>
-
-<p>This callback should release any resource currently in use, clear any active timer and reset the process to its original state, as it might be reused for future requests sent on the same connection.</p>
-
-<h3 id="callback">Callback(Req, State) -> {Value, Req, State} | {halt, Req, State}</h3>
-
-<p>Types:</p>

-<li>Req = cowboy_req:req()</li>
-<li>State = any()</li>
-<li>Value - see the REST callbacks description below</li>
-</ul>
-
-<p>Please see the REST callbacks description below for details on the <code>Value</code> type, the default value if the callback is not defined, and more general information on when the callback is called and what its intended use is.</p>
-
-<p>The <code>halt</code> tuple can be returned to stop REST processing. It is up to the resource code to send a reply before that, otherwise a <code>204 No Content</code> will be sent.</p>

-
-<p>Return the list of allowed methods.</p>
-
-<p>Methods are case sensitive. Standard methods are always uppercase.</p>

-
-<ul>
-<li>Methods: POST</li>
-<li>Value type: boolean()</li>
-<li>Default value: true</li>
-</ul>
-
-<p>Return whether POST is allowed when the resource doesn't exist.</p>
-
-<p>Returning <code>true</code> here means that a new resource will be created. The URL to the created resource should also be returned from the <code>AcceptResource</code> callback.</p>
-
-<h3 id="charsets_provided">charsets_provided</h3>
-
-<ul>
-<li>Methods: GET, HEAD, POST, PUT, PATCH, DELETE</li>
-<li>Value type: [binary()]</li>
-<li>Skip to the next step if undefined</li>
-</ul>
-
-<p>Return the list of charsets the resource provides.</p>
-
-<p>The list must be ordered in order of preference.</p>
-
-<p>If the accept-charset header was not sent, the first charset in the list will be selected. Otherwise Cowboy will select the most appropriate charset from the list.</p>
-
-<p>The chosen charset will be set in the <code>Req</code> object as the meta value <code>charset</code>.</p>

-<li>Value = [{binary() | {Type, SubType, Params}, AcceptResource}]</li>
-<li>Type = SubType = binary()</li>
-<li>Params = '*' | [{binary(), binary()}]</li>
-<li>AcceptResource = atom()</li>
-</ul>
-
-<p>Return the list of content-types the resource accepts.</p>
-
-<p>The list must be ordered in order of preference.</p>
-
-<p>Each content-type can be given either as a binary string or as a tuple containing the type, subtype and parameters.</p>
-
-<p>Cowboy will select the most appropriate content-type from the list. If any parameter is acceptable, then the tuple form should be used with parameters set to <code>'*'</code>. If the parameters value is set to <code>[]</code> only content-type values with no parameters will be accepted. All parameter values are treated in a case sensitive manner except the <code>charset</code> parameter, if present, which is case insensitive.</p>
-
-<p>This function will be called for POST, PUT and PATCH requests. It is entirely possible to define different callbacks for different methods if the handling of the request differs. Simply verify what the method is with <code>cowboy_req:method/1</code> and return a different list for each methods.</p>
-
-<p>The <code>AcceptResource</code> value is the name of the callback that will be called if the content-type matches. It is defined as follow.</p>
-
-<ul>
-<li>Value type: true | {true, URL} | false</li>
-<li>No default</li>
-</ul>
-
-<p>Process the request body.</p>
-
-<p>This function should create or update the resource with the information contained in the request body. This information may be full or partial depending on the request method.</p>
-
-<p>If the request body was processed successfully, <code>true</code> must be returned. If the request method is POST, <code>{true, URL}</code> may be returned instead, and Cowboy will redirect the client to the location of the newly created resource.</p>
-
-<p>If a response body must be sent, the appropriate media-type, charset and language can be retrieved using the <code>cowboy_req:meta/{2,3}</code> functions. The respective keys are <code>media_type</code>, <code>charset</code> and <code>language</code>. The body can be set using <code>cowboy_req:set_resp_body/2</code>.</p>

-<h3 id="content_types_provided">content_types_provided</h3>
-
-<ul>
-<li>Methods: GET, HEAD, POST, PUT, PATCH, DELETE</li>
-<li>Default value: [{{<<"text">>, <<"html">>, '*'}, to_html}]</li>
-</ul>
-
-<p>Types:</p>
-
-<ul>
-<li>Value = [{binary() | {Type, SubType, Params}, ProvideResource}]</li>
-<li>Type = SubType = binary()</li>
-<li>Params = '*' | [{binary(), binary()}]</li>
-<li>ProvideResource = atom()</li>
-</ul>
-
-<p>Return the list of content-types the resource provides.</p>
-
-<p>The list must be ordered in order of preference.</p>
-
-<p>Each content-type can be given either as a binary string or as a tuple containing the type, subtype and parameters.</p>
-
-<p>Cowboy will select the most appropriate content-type from the list. If any parameter is acceptable, then the tuple form should be used with parameters set to <code>'*'</code>. If the parameters value is set to <code>[]</code> only content-type values with no parameters will be accepted. All parameter values are treated in a case sensitive manner except the <code>charset</code> parameter, if present, which is case insensitive.</p>
-
-<p>The <code>ProvideResource</code> value is the name of the callback that will be called if the content-type matches. It will only be called when a representation of the resource needs to be returned. It is defined as follow.</p>
-
-<ul>
-<li>Methods: GET, HEAD</li>
-<li>Value type: iodata() | {stream, Fun} | {stream, Len, Fun} | {chunked, ChunkedFun}</li>
-<li>No default</li>
-</ul>
-
-<p>Return the response body.</p>
-
-<p>The response body may be provided directly or through a fun. If a fun tuple is returned, the appropriate <code>set_resp_body_fun</code> function will be called. Please refer to the documentation for these functions for more information about the types.</p>
-
-<p>The call to this callback happens a good time after the call to <code>content_types_provided/2</code>, when it is time to start rendering the response body.</p>
-
-<h3 id="delete_completed">delete_completed</h3>
-
-<ul>
-<li>Methods: DELETE</li>
-<li>Value type: boolean()</li>
-<li>Default value: true</li>
-</ul>
-
-<p>Return whether the delete action has been completed.</p>
-
-<p>This function should return <code>false</code> if there is no guarantee that the resource gets deleted immediately from the system, including from any internal cache.</p>
-
-<p>When this function returns <code>false</code>, a <code>202 Accepted</code> response will be sent instead of a <code>200 OK</code> or <code>204 No Content</code>.</p>
-
-<h3 id="delete_resource">delete_resource</h3>
-
-<ul>
-<li>Methods: DELETE</li>

-<li>Methods: all</li>
-<li>Value type: boolean()</li>
-<li>Default value: false</li>
-</ul>
-
-<p>Return whether access to the resource is forbidden.</p>
-
-<p>A <code>403 Forbidden</code> response will be sent if this function returns <code>true</code>. This status code means that access is forbidden regardless of authentication, and that the request shouldn't be repeated.</p>
-
-<h3 id="generate_etag">generate_etag</h3>
-
-<ul>
-<li>Methods: GET, HEAD, POST, PUT, PATCH, DELETE</li>
-<li>Value type: binary() | {weak | strong, binary()}</li>
-<li>Default value: undefined</li>
-</ul>
-
-<p>Return the entity tag of the resource.</p>
-
-<p>This value will be sent as the value of the etag header.</p>
-
-<p>If a binary is returned, then the value will be parsed to the tuple form automatically. The value must be in the same format as the etag header, including quotes.</p>
-
-<h3 id="is_authorized">is_authorized</h3>

-<ul>
-<li>Methods: PUT</li>
-<li>Value type: boolean()</li>
-<li>Default value: false</li>
-</ul>
-
-<p>Return whether the put action results in a conflict.</p>
-
-<p>A <code>409 Conflict</code> response will be sent if this function returns <code>true</code>.</p>
-
-<h3 id="known_content_type">known_content_type</h3>

-
-<ul>
-<li>Methods: all</li>
-<li>Value type: [binary()]</li>
-<li>Default value: [<<"GET">>, <<"HEAD">>, <<"POST">>, <<"PUT">>, <<"PATCH">>, <<"DELETE">>, <<"OPTIONS">>]</li>
-</ul>
-
-<p>Return the list of known methods.</p>
-
-<p>The full list of methods known by the server should be returned, regardless of their use in the resource.</p>
-
-<p>The default value lists the methods Cowboy knows and implement in <code>cowboy_rest</code>.</p>
-
-<p>Methods are case sensitive. Standard methods are always uppercase.</p>
-
-<h3 id="languages_provided">languages_provided</h3>
-
-<ul>
-<li>Methods: GET, HEAD, POST, PUT, PATCH, DELETE</li>
-<li>Value type: [binary()]</li>
-<li>Skip to the next step if undefined</li>
-</ul>
-
-<p>Return the list of languages the resource provides.</p>
-
-<p>The list must be ordered in order of preference.</p>
-
-<p>If the accept-language header was not sent, the first language in the list will be selected. Otherwise Cowboy will select the most appropriate language from the list.</p>
-
-<p>The chosen language will be set in the <code>Req</code> object as the meta value <code>language</code>.</p>
-
-<p>While languages are case insensitive, this callback is expected to return them as lowercase binary.</p>
-
-<h3 id="last_modified">last_modified</h3>
-
-<ul>
-<li>Methods: GET, HEAD, POST, PUT, PATCH, DELETE</li>
-<li>Value type: calendar:datetime()</li>
-<li>Default value: undefined</li>
-</ul>
-
-<p>Return the date of last modification of the resource.</p>
-
-<p>This date will be used to test against the if-modified-since and if-unmodified-since headers, and sent as the last-modified header in the response of GET and HEAD requests.</p>
-
-<h3 id="malformed_request">malformed_request</h3>
-
-<ul>
-<li>Methods: all</li>
-<li>Value type: boolean()</li>
-<li>Default value: false</li>
-</ul>
-
-<p>Return whether the request is malformed.</p>
-
-<p>Cowboy has already performed all the necessary checks by the time this function is called, so few resources are expected to implement it.</p>
-
-<p>The check is to be done on the request itself, not on the request body, which is processed later.</p>
-
-<h3 id="moved_permanently">moved_permanently</h3>
-
-<ul>
-<li>Methods: GET, HEAD, POST, PUT, PATCH, DELETE</li>
-<li>Value type: {true, URL} | false</li>
-<li>Default value: false</li>

-<li>Value type: boolean()</li>
-<li>Default value: false</li>
-</ul>
-
-<p>Return whether there are multiple representations of the resource.</p>
-
-<p>This function should be used to inform the client if there are different representations of the resource, for example different content-type. If this function returns <code>true</code>, the response body should include information about these different representations using <code>cowboy_req:set_resp_body/2</code>. The content-type of the response should be the one previously negociated and that can be obtained by calling <code>cowboy_req:meta(media_type, Req)</code>.</p>
-
-<h3 id="options">options</h3>
-
-<ul>
-<li>Methods: OPTIONS</li>
-<li>Value type: ok</li>
-<li>Default value: ok</li>
-</ul>
-
-<p>Handle a request for information.</p>
-
-<p>The response should inform the client the communication options available for this resource.</p>

-<li>Value type: boolean()</li>
-<li>Default value: true</li>
-</ul>
-
-<p>Return whether the resource exists.</p>
-
-<p>If it exists, conditional headers will be tested before attempting to perform the action. Otherwise, Cowboy will check if the resource previously existed first.</p>
-
-<h3 id="service_available">service_available</h3>
-
-<ul>
-<li>Methods: all</li>
-<li>Value type: boolean()</li>
-<li>Default value: true</li>
-</ul>
-
-<p>Return whether the service is available.</p>
-
-<p>This function can be used to test that all relevant backend systems are up and able to handle requests.</p>
-
-<p>A <code>503 Service Unavailable</code> response will be sent if this function returns <code>false</code>.</p>
-
-<h3 id="uri_too_long">uri_too_long</h3>
-
-<ul>
-<li>Methods: all</li>
-<li>Value type: boolean()</li>
-<li>Default value: false</li>
-</ul>
-
-<p>Return whether the requested URI is too long.</p>
-
-<p>Cowboy has already performed all the necessary checks by the time this function is called, so few resources are expected to implement it.</p>
-
-<p>A <code>414 Request-URI Too Long</code> response will be sent if this function returns <code>true</code>.</p>
-
-<h3 id="valid_content_headers">valid_content_headers</h3>
-
-<ul>
-<li>Methods: all</li>
-<li>Value type: boolean()</li>
-<li>Default value: true</li>
-</ul>
-
-<p>Return whether the content-* headers are valid.</p>
-
-<p>This also applies to the transfer-encoding header. This function must return <code>false</code> for any unknown content-* headers, or if the headers can't be understood. The function <code>cowboy_req:parse_header/2</code> can be used to quickly check the headers can be parsed.</p>
-
-<p>A <code>501 Not Implemented</code> response will be sent if this function returns <code>false</code>.</p>
-
-<h3 id="valid_entity_length">valid_entity_length</h3>
-
-<ul>
-<li>Methods: all</li>
-<li>Value type: boolean()</li>
-<li>Default value: true</li>
-</ul>
-
-<p>Return whether the request body length is within acceptable boundaries.</p>
-
-<p>A <code>413 Request Entity Too Large</code> response will be sent if this function returns <code>false</code>.</p>
-
-<h3 id="variances">variances</h3>
-
-<ul>
-<li>Methods: GET, HEAD, POST, PUT, PATCH, DELETE</li>
-<li>Value type: [binary()]</li>
-<li>Default value: []</li>
-</ul>
-
-<p>Return the list of headers that affect the representation of the resource.</p>
-
-<p>These request headers return the same resource but with different parameters, like another language or a different content-type.</p>
-
-<p>Cowboy will automatically add the accept, accept-language and accept-charset headers to the list if the respective functions were defined in the resource.</p>
-
-<p>This operation is performed right before the <code>resource_exists/2</code> callback. All responses past that point will contain the vary header which holds this list.</p>

-<p>The <code>cowboy_router</code> middleware maps the requested host and path to the handler to be used for processing the request. It uses the dispatch rules compiled from the routes given to the <code>compile/1</code> function for this purpose. It adds the handler name and options to the environment as the values <code>handler</code> and <code>handler_opts</code> respectively.</p>

-
-<p>The <code>cowboy_websocket_handler</code> behaviour defines the interface used by Websocket handlers.</p>
-
-<p>The <code>init/3</code> and <code>websocket_init/3</code> callbacks will always be called, followed by zero or more calls to <code>websocket_handle/3</code> and <code>websocket_info/3</code>. The <code>websocket_terminate/3</code> will always be called last.</p>
-
-<h2 id="types">Types</h2>

-<h2 id="callbacks">Callbacks</h2>
-
-<h3 id="init">init({TransportName, ProtocolName}, Req, Opts) -> {upgrade, protocol, cowboy_websocket} | {upgrade, protocol, cowboy_websocket, Req, Opts}</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>TransportName = tcp | ssl | atom()</li>
-<li>ProtocolName = http | atom()</li>
-<li>Req = cowboy_req:req()</li>
-<li>Opts = any()</li>
-</ul>
-
-<p>Upgrade the protocol to <code>cowboy_websocket</code>.</p>
-
-<h3 id="websocket_init">websocket_init(TransportName, Req, Opts) -> {ok, Req, State} | {ok, Req, State, hibernate} | {ok, Req, State, Timeout} | {ok, Req, State, Timeout, hibernate} | {shutdown, Req}</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>TransportName = tcp | ssl | atom()</li>
-<li>Req = cowboy_req:req()</li>
-<li>Opts = any()</li>
-<li>State = any()</li>
-<li>Timeout = timeout()</li>
-</ul>
-
-<p>Initialize the state for this session.</p>
-
-<p>This function is called before the upgrade to Websocket occurs. It can be used to negotiate Websocket protocol extensions with the client. It will typically be used to register this process to an event manager or a message queue in order to receive the messages the handler wants to process.</p>
-
-<p>The connection will stay up for a duration of up to <code>Timeout</code> milliseconds after it last received data from the socket, at which point it will stop and close the connection. By default this value is set to <code>infinity</code>. It is recommended to either set this value or ensure by any other mechanism that the handler will be closed after a certain period of inactivity.</p>
-
-<p>The <code>hibernate</code> option will hibernate the process until it starts receiving either data from the Websocket connection or Erlang messages.</p>
-
-<p>The <code>shutdown</code> return value can be used to close the connection before upgrading to Websocket.</p>
-
-<h3 id="websocket_handle">websocket_handle(InFrame, Req, State) -> {ok, Req, State} | {ok, Req, State, hibernate} | {reply, OutFrame | [OutFrame], Req, State} | {reply, OutFrame | [OutFrame], Req, State, hibernate} | {shutdown, Req, State}</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>InFrame = {text | binary | ping | pong, binary()}</li>
-<li>Req = cowboy_req:req()</li>
-<li>State = any()</li>
-<li>OutFrame = cowboy_websocket:frame()</li>
-</ul>
-
-<p>Handle the data received from the Websocket connection.</p>
-
-<p>This function will be called every time data is received from the Websocket connection.</p>
-
-<p>The <code>shutdown</code> return value can be used to close the connection. A close reply will also result in the connection being closed.</p>
-
-<p>The <code>hibernate</code> option will hibernate the process until it receives new data from the Websocket connection or an Erlang message.</p>
-
-<h3 id="websocket_info">websocket_info(Info, Req, State) -> {ok, Req, State} | {ok, Req, State, hibernate} | {reply, OutFrame | [OutFrame], Req, State} | {reply, OutFrame | [OutFrame], Req, State, hibernate} | {shutdown, Req, State}</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>Info = any()</li>
-<li>Req = cowboy_req:req()</li>
-<li>State = any()</li>
-<li>OutFrame = cowboy_websocket:frame()</li>
-</ul>
-
-<p>Handle the Erlang message received.</p>
-
-<p>This function will be called every time an Erlang message has been received. The message can be any Erlang term.</p>
-
-<p>The <code>shutdown</code> return value can be used to close the connection. A close reply will also result in the connection being closed.</p>
-
-<p>The <code>hibernate</code> option will hibernate the process until it receives another message or new data from the Websocket connection.</p>
-
-<h3 id="websocket_terminate">websocket_terminate(Reason, Req, State) -> ok</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>Reason = {normal, shutdown | timeout} | {remote, closed} | {remote, cowboy_websocket:close_code(), binary()} | {error, badencoding | badframe | closed | atom()}</li>
-<li>Req = cowboy_req:req()</li>
-<li>State = any()</li>
-</ul>
-
-<p>Perform any necessary cleanup of the state.</p>
-
-<p>The connection will be closed and the process stopped right after this call.</p>

+
+		<p>Last week I was speaking at the London Erlang Factory Lite where I presented a live demonstration of building an FTP server using Ranch. As there was no slide, you should use this article as a reference instead.
+The goal of this article is to showcase how to use Ranch for writing a network protocol implementation, how Ranch gets out of the way to let you write the code that matters, and the common techniques used when writing servers.</p>

+
+<p>Ranch <code>2.0.0-rc.1</code> has been released!</p>
+<p>We are getting very close to releasing Ranch 2.0! As most of the tremendous programming work was done by contributor Jan Uhlig, I will yield the floor and let him describe what went into this great release.</p>
+<p>In Ranch 1.x, there is only one supervisor per Ranch listener to start and manage connection processes. Under high load (many clients rapidly connecting and/or disconnecting), the message queue of this one supervisor could becomes congested, leading to declining accept rates or a stalled listener.</p>
+<p>Ranch 2.0 introduces the <code>num_conns_sups</code> option (defaulting to the number of acceptors), which allows the message load to be divided between the specified number of connection supervisors. This improves accept concurrency at the same time.</p>
+<p>Another bottleneck is a possible congestion of the syn queue of a listening socket. The reason is located within the operating system&apos;s TCP/IP implementation, and on Linux the <code>SO_REUSEPORT</code> socket option was introduced to address it. What it boils down to is that you can have more than just one socket listening on the same port, causing the sockets to be load-balanced when accepting connections.</p>
+<p>Ranch 1.x always uses a single listening socket per listener, shared between the acceptors. With a trick, starting multiple Ranch listeners on the same port, it is already possible to make use of the <code>SO_REUSEPORT</code> feature. But that&apos;s not ideal.</p>
+<p>Ranch 2.0 introduces the <code>num_listen_sockets</code> option, which allows to specify the number of listening sockets a Ranch listener should employ, without having to use this trick. Whether you can use <code>SO_REUSEPORT</code> at all and how to enable it depends on your operating system, though.</p>
+<p>Other changes include proper support for local (Unix Domain) sockets, removing the restriction that a listener be suspended to change its transport options and much needed improvements to embedded listeners.</p>
+<p>In addition we have had patches merged to Erlang/OTP to add support for active N to the <code>ssl</code> application (requires Erlang/OTP 21.3 or above) and fix a number of smaller issues we encountered. We have also helped detect and fix a bug in the Windows implementation of active N that greatly reduced its performance in some cases.</p>
+<p>To ensure that everything works correctly, new tests have been written, and some existing tests were updated. A noteworthy addition in this area is pitting Ranch against <a href="https://github.com/ankhers/havoc">Havoc</a>, a resilience testing tool that kills random processes and ports in the system.</p>
+<p>Cowboy users wishing to try Ranch 2.0.0-rc.1 will need to use Cowboy&apos;s master branch at this time or wait for the upcoming Cowboy 2.7.0. Cowboy has been made compatible with both Ranch 1 and 2.</p>
+<p>Last but not least, aside from the changes mentioned above, we are currently preparing a <a href="https://github.com/juhlig/prometheus_ranch">Prometheus collector</a> for Ranch as well as an accompanying Grafana dashboard.</p>
+<p>Ranch 2.0 requires Erlang/OTP 21 or above and is tested and supported on Linux, FreeBSD, macOS and Windows.</p>
+<p>A complete list of changes can be found in the migration guide: <a href="https://ninenines.eu/docs/en/ranch/2.0/guide/migrating_from_1.7/">Migrating from Ranch 1.7 to 2.0</a>.</p>
+<p>You can donate to this project via <a href="https://salt.bountysource.com/teams/ninenines">BountySource</a>. These funds are used to pay for additional servers for testing. We will soon add two Raspberry Pi 4 in order to have some ARM targets when testing.</p>
+<p>As usual, feedback is appreciated, and issues or questions should be sent via Github tickets. Thanks!</p>

-
-<p>Cowboy is a lightweight HTTP server.</p>
-
-<p>It is built on top of Ranch. Please see the Ranch guide for more information.</p>
-
-<h2 id="one_process_per_connection">One process per connection</h2>
-
-<p>It uses only one process per connection. The process where your code runs is the process controlling the socket. Using one process instead of two allows for lower memory usage.</p>
-
-<p>Because there can be more than one request per connection with the keepalive feature of HTTP/1.1, that means the same process will be used to handle many requests.</p>
-
-<p>Because of this, you are expected to make sure your process cleans up before terminating the handling of the current request. This may include cleaning up the process dictionary, timers, monitoring and more.</p>
-
-<h2 id="binaries">Binaries</h2>
-
-<p>It uses binaries. Binaries are more efficient than lists for representing strings because they take less memory space. Processing performance can vary depending on the operation. Binaries are known for generally getting a great boost if the code is compiled natively. Please see the HiPE documentation for more details.</p>
-
-<h2 id="date_header">Date header</h2>
-
-<p>Because querying for the current date and time can be expensive, Cowboy generates one <code>Date</code> header value every second, shares it to all other processes, which then simply copy it in the response. This allows compliance with HTTP/1.1 with no actual performance loss.</p>
-
-<h2 id="max_connections">Max connections</h2>
-
-<p>By default the maximum number of active connections is set to a generally accepted big enough number. This is meant to prevent having too many processes performing potentially heavy work and slowing everything else down, or taking up all the memory.</p>
-
-<p>Disabling this feature, by setting the <code>{max_connections, infinity}</code> protocol option, would give you greater performance when you are only processing short-lived requests.</p>

-<h1 class="lined-header"><span>Dealing with broken clients</span></h1>
-
-<p>There exists a very large number of implementations for the HTTP protocol. Most widely used clients, like browsers, follow the standard quite well, but others may not. In particular custom enterprise clients tend to be very badly written.</p>
-
-<p>Cowboy tries to follow the standard as much as possible, but is not trying to handle every possible special cases. Instead Cowboy focuses on the cases reported in the wild, on the public Web.</p>
-
-<p>That means clients that ignore the HTTP standard completely may fail to understand Cowboy's responses. There are of course workarounds. This chapter aims to cover them.</p>
-
-<h2 id="lowercase_headers">Lowercase headers</h2>
-
-<p>Cowboy converts all headers it receives to lowercase, and similarly sends back headers all in lowercase. Some broken HTTP clients have issues with that.</p>
-
-<p>A simple way to solve this is to create an <code>onresponse</code> hook that will format the header names with the expected case.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-capitalize_hook(Status, Headers, Body, Req) ->
-    Headers2 = [{cowboy_bstr:capitalize_token(N), V}
-        || {N, V} <- Headers],
-    {ok, Req2} = cowboy_req:reply(Status, Headers2, Body, Req),
-    Req2.
-]]></script>
-
-<p>Note that SPDY clients do not have that particular issue because the specification explicitly says all headers are lowercase, unlike HTTP which allows any case but treats them as case insensitive.</p>
-
-<h2 id="camel-case_headers">Camel-case headers</h2>
-
-<p>Sometimes it is desirable to keep the actual case used by clients, for example when acting as a proxy between two broken implementations. There is no easy solution for this other than forking the project and editing the <code>cowboy_protocol</code> file directly.</p>
-
-<h2 id="chunked_transfer-encoding">Chunked transfer-encoding</h2>
-
-<p>Sometimes an HTTP client advertises itself as HTTP/1.1 but does not support chunked transfer-encoding. This is invalid behavior, as HTTP/1.1 clients are required to support it.</p>
-
-<p>A simple workaround exists in these cases. By changing the Req object response state to <code>waiting_stream</code>, Cowboy will understand that it must use the identity transfer-encoding when replying, just like if it was an HTTP/1.0 client.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-Req2 = cowboy_req:set(resp_state, waiting_stream).

-<h1 class="lined-header"><span>Using cookies</span></h1>
-
-<p>Cookies are a mechanism allowing applications to maintain state on top of the stateless HTTP protocol.</p>
-
-<p>Cowboy provides facilities for handling cookies. It is highly recommended to use them instead of writing your own, as the implementation of cookies can vary greatly between clients.</p>
-
-<p>Cookies are stored client-side and sent with every subsequent request that matches the domain and path for which they were stored, including requests for static files. For this reason they can incur a cost which must be taken in consideration.</p>
-
-<p>Also consider that, regardless of the options used, cookies are not to be trusted. They may be read and modified by any program on the user's computer, but also by proxies. You should always validate cookie values before using them. Do not store any sensitive information in cookies either.</p>
-
-<p>When explicitly setting the domain, the cookie will be sent for the domain and all subdomains from that domain. Otherwise the current domain will be used. The same is true for the path.</p>
-
-<p>When the server sets cookies, they will only be available for requests that are sent after the client receives the response.</p>
-
-<p>Cookies are sent in HTTP headers, therefore they must have text values. It is your responsibility to encode any other data type. Also note that cookie names are de facto case sensitive.</p>
-
-<p>Cookies can be set for the client session (which generally means until the browser is closed), or it can be set for a number of seconds. Once it expires, or when the server says the cookie must exist for up to 0 seconds, the cookie is deleted by the client. To avoid this while the user is browsing your site, you should set the cookie for every request, essentially resetting the expiration time.</p>
-
-<p>Cookies can be restricted to secure channels. This typically means that such a cookie will only be sent over HTTPS, and that it will only be available by client-side scripts that run from HTTPS webpages.</p>
-
-<p>Finally, cookies can be restricted to HTTP and HTTPS requests, essentially disabling their access from client-side scripts.</p>
-
-<h2 id="setting_cookies">Setting cookies</h2>
-
-<p>By default, cookies you set are defined for the session.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-SessionID = generate_session_id(),
-Req2 = cowboy_req:set_resp_cookie(<<"sessionid">>, SessionID, [], Req).
-]]></script>
-
-<p>You can also make them expire at a specific point in the future.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-SessionID = generate_session_id(),
-Req2 = cowboy_req:set_resp_cookie(<<"sessionid">>, SessionID, [
-    {max_age, 3600}
-], Req).
-]]></script>
-
-<p>You can delete cookies that have already been set. The value is ignored.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-Req2 = cowboy_req:set_resp_cookie(<<"sessionid">>, <<>>, [
-    {max_age, 0}
-], Req).
-]]></script>
-
-<p>You can restrict them to a specific domain and path. For example, the following cookie will be set for the domain <code>my.example.org</code> and all its subdomains, but only on the path <code>/account</code> and all its subdirectories.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-Req2 = cowboy_req:set_resp_cookie(<<"inaccount">>, <<"1">>, [
-    {domain, "my.example.org"},
-    {path, "/account"}
-], Req).
-]]></script>
-
-<p>You can restrict the cookie to secure channels, typically HTTPS.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-SessionID = generate_session_id(),
-Req2 = cowboy_req:set_resp_cookie(<<"sessionid">>, SessionID, [
-    {secure, true}
-], Req).
-]]></script>
-
-<p>You can restrict the cookie to client-server communication only. Such a cookie will not be available to client-side scripts.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-SessionID = generate_session_id(),
-Req2 = cowboy_req:set_resp_cookie(<<"sessionid">>, SessionID, [
-    {http_only, true}
-], Req).
-]]></script>
-
-<p>Cookies may also be set client-side, for example using Javascript.</p>
-
-<h2 id="reading_cookies">Reading cookies</h2>
-
-<p>As we said, the client sends cookies with every request. But unlike the server, the client only sends the cookie name and value.</p>
-
-<p>You can read the value of a cookie.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{CookieVal, Req2} = cowboy_req:cookie(<<"lang">>, Req).
-]]></script>
-
-<p>You can also get a default value returned when the cookie isn't set.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{CookieVal, Req2} = cowboy_req:cookie(<<"lang">>, Req, <<"fr">>).
-]]></script>
-
-<p>And you can obtain all cookies at once as a list of key/value tuples.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{AllCookies, Req2} = cowboy_req:cookies(Req).
-]]></script>

-<h1 class="lined-header"><span>Erlang for beginners</span></h1>
-
-<p>Chances are you are interested in using Cowboy, but have no idea how to write an Erlang program. Fear not! This chapter will help you get started.</p>
-
-<p>We recommend two books for beginners. You should read them both at some point, as they cover Erlang from two entirely different perspectives.</p>
-
-<h2 id="learn_you_some_erlang_for_great_good!">Learn You Some Erlang for Great Good!</h2>
-
-<p>The quickest way to get started with Erlang is by reading a book with the funny name of <a href="http://learnyousomeerlang.com">LYSE</a>, as we affectionately call it.</p>
-
-<p>It will get right into the syntax and quickly answer the questions a beginner would ask themselves, all the while showing funny pictures and making insightful jokes.</p>
-
-<p>You can read an early version of the book online for free, but you really should buy the much more refined paper and ebook versions.</p>
-
-<h2 id="programming_erlang">Programming Erlang</h2>
-
-<p>After writing some code, you will probably want to understand the very concepts that make Erlang what it is today. These are best explained by Joe Armstrong, the godfather of Erlang, in his book <a href="http://pragprog.com/book/jaerlang2/programming-erlang">Programming Erlang</a>.</p>
-
-<p>Instead of going into every single details of the language, Joe focuses on the central concepts behind Erlang, and shows you how they can be used to write a variety of different applications.</p>
-
-<p>At the time of writing, the 2nd edition of the book is in beta, and includes a few details about upcoming Erlang features that cannot be used today. Choose the edition you want, then get reading!</p>

-<h1 class="lined-header"><span>Erlang and the Web</span></h1>
-
-<h2 id="the_web_is_concurrent">The Web is concurrent</h2>
-
-<p>When you access a website there is little concurrency involved. A few connections are opened and requests are sent through these connections. Then the web page is displayed on your screen. Your browser will only open up to 4 or 8 connections to the server, depending on your settings. This isn't much.</p>
-
-<p>But think about it. You are not the only one accessing the server at the same time. There can be hundreds, if not thousands, if not millions of connections to the same server at the same time.</p>
-
-<p>Even today a lot of systems used in production haven't solved the C10K problem (ten thousand concurrent connections). And the ones who did are trying hard to get to the next step, C100K, and are pretty far from it.</p>
-
-<p>Erlang meanwhile has no problem handling millions of connections. At the time of writing there are application servers written in Erlang that can handle more than two million connections on a single server in a real production application, with spare memory and CPU!</p>
-
-<p>The Web is concurrent, and Erlang is a language designed for concurrency, so it is a perfect match.</p>
-
-<p>Of course, various platforms need to scale beyond a few million connections. This is where Erlang's built-in distribution mechanisms come in. If one server isn't enough, add more! Erlang allows you to use the same code for talking to local processes or to processes in other parts of your cluster, which means you can scale very quickly if the need arises.</p>
-
-<p>The Web has large userbases, and the Erlang platform was designed to work in a distributed setting, so it is a perfect match.</p>
-
-<p>Or is it? Surely you can find solutions to handle that many concurrent connections with your favorite language... But all these solutions will break down in the next few years. Why? Firstly because servers don't get any more powerful, they instead get a lot more cores and memory. This is only useful if your application can use them properly, and Erlang is light-years away from anything else in that area. Secondly, today your computer and your phone are online, tomorrow your watch, goggles, bike, car, fridge and tons of other devices will also connect to various applications on the Internet.</p>
-
-<p>Only Erlang is prepared to deal with what's coming.</p>
-
-<h2 id="the_web_is_soft_real_time">The Web is soft real time</h2>
-
-<p>What does soft real time mean, you ask? It means we want the operations done as quickly as possible, and in the case of web applications, it means we want the data propagated fast.</p>
-
-<p>In comparison, hard real time has a similar meaning, but also has a hard time constraint, for example an operation needs to be done in under N milliseconds otherwise the system fails entirely.</p>
-
-<p>Users aren't that needy yet, they just want to get access to their content in a reasonable delay, and they want the actions they make to register at most a few seconds after they submitted them, otherwise they'll start worrying about whether it successfully went through.</p>
-
-<p>The Web is soft real time because taking longer to perform an operation would be seen as bad quality of service.</p>
-
-<p>Erlang is a soft real time system. It will always run processes fairly, a little at a time, switching to another process after a while and preventing a single process to steal resources from all others. This means that Erlang can guarantee stable low latency of operations.</p>
-
-<p>Erlang provides the guarantees that the soft real time Web requires.</p>
-
-<h2 id="the_web_is_asynchronous">The Web is asynchronous</h2>
-
-<p>Long ago, the Web was synchronous because HTTP was synchronous. You fired a request, and then waited for a response. Not anymore. It all began when XmlHttpRequest started being used. It allowed the client to perform asynchronous calls to the server.</p>
-
-<p>Then Websocket appeared and allowed both the server and the client to send data to the other endpoint completely asynchronously. The data is contained within frames and no response is necessary.</p>
-
-<p>Erlang processes work the same. They send each other data contained within messages and then continue running without needing a response. They tend to spend most of their time inactive, waiting for a new message, and the Erlang VM happily activate them when one is received.</p>
-
-<p>It is therefore quite easy to imagine Erlang being good at receiving Websocket frames, which may come in at unpredictable times, pass the data to the responsible processes which are always ready waiting for new messages, and perform the operations required by only activating the required parts of the system.</p>
-
-<p>The more recent Web technologies, like Websocket of course, but also SPDY and HTTP/2.0, are all fully asynchronous protocols. The concept of requests and responses is retained of course, but anything could be sent in between, by both the client or the browser, and the responses could also be received in a completely different order.</p>
-
-<p>Erlang is by nature asynchronous and really good at it thanks to the great engineering that has been done in the VM over the years. It's only natural that it's so good at dealing with the asynchronous Web.</p>
-
-<h2 id="the_web_is_omnipresent">The Web is omnipresent</h2>
-
-<p>The Web has taken a very important part of our lives. We're connected at all times, when we're on our phone, using our computer, passing time using a tablet while in the bathroom... And this isn't going to slow down, every single device at home or on us will be connected.</p>
-
-<p>All these devices are always connected. And with the number of alternatives to give you access to the content you seek, users tend to not stick around when problems arise. Users today want their applications to be always available and if it's having too many issues they just move on.</p>
-
-<p>Despite this, when developers choose a product to use for building web applications, their only concern seem to be "Is it fast?", and they look around for synthetic benchmarks showing which one is the fastest at sending "Hello world" with only a handful concurrent connections. Web benchmarks haven't been representative of reality in a long time, and are drifting further away as time goes on.</p>
-
-<p>What developers should really ask themselves is "Can I service all my users with no interruption?" and they'd find that they have two choices. They can either hope for the best, or they can use Erlang.</p>
-
-<p>Erlang is built for fault tolerance. When writing code in any other language, you have to check all the return values and act accordingly to avoid any unforeseen issues. If you're lucky, you won't miss anything important. When writing Erlang code, you can just check the success condition and ignore all errors. If an error happen, the Erlang process crashes and is then restarted by a special process called a supervisor.</p>
-
-<p>The Erlang developer thus has no need to fear about unhandled errors, and can focus on handling only the errors that should give some feedback to the user and let the system take care of the rest. This also has the advantage of allowing him to write a lot less code, and letting him sleep at night.</p>
-
-<p>Erlang's fault tolerance oriented design is the first piece of what makes it the best choice for the omnipresent, always available Web.</p>
-
-<p>The second piece is Erlang's built-in distribution. Distribution is a key part of building a fault tolerant system, because it allows you to handle bigger failures, like a whole server going down, or even a data center entirely.</p>
-
-<p>Fault tolerance and distribution are important today, and will be vital in the future of the Web. Erlang is ready.</p>
-
-<h2 id="erlang_is_the_ideal_platform_for_the_web">Erlang is the ideal platform for the Web</h2>
-
-<p>Erlang provides all the important features that the Web requires or will require in the near future. Erlang is a perfect match for the Web, and it only makes sense to use it to build web applications.</p>

-
-<p>Erlang is more than a language, it is also an operating system for your applications. Erlang developers rarely write standalone modules, they write libraries or applications, and then bundle those into what is called a release. A release contains the Erlang VM plus all applications required to run the node, so it can be pushed to production directly.</p>
-
-<p>This chapter walks you through all the steps of setting up Cowboy, writing your first application and generating your first release. At the end of this chapter you should know everything you need to push your first Cowboy application to production.</p>
-
-<h2 id="bootstrap">Bootstrap</h2>
-
-<p>We are going to use the <a href="https://github.com/ninenines/erlang.mk">erlang.mk</a> build system. It also offers bootstrap features allowing us to quickly get started without having to deal with minute details.</p>
-
-<p>First, let's create the directory for our application.</p>
-
-<script type="syntaxhighlighter" class="brush: bash"><![CDATA[
-$ mkdir hello_erlang
-$ cd hello_erlang
-]]></script>
-
-<p>Then we need to download <code>erlang.mk</code>. Either use the following command or download it manually.</p>
-
-<script type="syntaxhighlighter" class="brush: bash"><![CDATA[
-$ wget https://raw.githubusercontent.com/ninenines/erlang.mk/master/erlang.mk
-]]></script>
-
-<p>We can now bootstrap our application. Since we are going to generate a release, we will also bootstrap it at the same time.</p>
-
-<script type="syntaxhighlighter" class="brush: bash"><![CDATA[
-$ make -f erlang.mk bootstrap bootstrap-rel
-]]></script>
-
-<p>This creates a Makefile, a base application, and the release files necessary for creating the release. We can already build and start this release.</p>
-
-<script type="syntaxhighlighter" class="brush: bash"><![CDATA[
-$ make
-...
-$ ./_rel/hello_erlang_release/bin/hello_erlang_release console
-...
-([email protected])1>
-]]></script>
-
-<p>Entering the command <code>i().</code> will show the running processes, including one called <code>hello_erlang_sup</code>. This is the supervisor for our application.</p>
-
-<p>The release currently does nothing. In the rest of this chapter we will add Cowboy as a dependency and write a simple "Hello world!" handler.</p>
-
-<h2 id="cowboy_setup">Cowboy setup</h2>
-
-<p>To add Cowboy as a dependency to your application, you need to modify two files: the Makefile and the application resource file.</p>
-
-<p>Modifying the Makefile allows the build system to know it needs to fetch and compile Cowboy. To do that we simply need to add one line to our Makefile to make it look like this:</p>
-
-<script type="syntaxhighlighter" class="brush: plain"><![CDATA[
-PROJECT = hello_erlang
-DEPS = cowboy
-include erlang.mk
-]]></script>
-
-<p>Modifying the application resource file, <code>src/hello_erlang.app.src</code>, allows the build system to know it needs to include Cowboy in the release and start it automatically. This is a different step because some dependencies are only needed during development.</p>
-
-<p>We are simply going to add <code>cowboy</code> to the list of <code>applications</code>, right after <code>stdlib</code>. Don't forget the comma separator.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{application, hello_erlang, [
-	{description, "Hello Erlang!"},
-	{vsn, "0.1.0"},
-	{modules, []},
-	{registered, []},
-	{applications, [
-		kernel,
-		stdlib,
-		cowboy
-	]},
-	{mod, {hello_erlang_app, []}},
-	{env, []}
-]}.
-]]></script>
-
-<p>You may want to set a description for the application while you are editing the file.</p>
-
-<p>If you run <code>make</code> now and start the release, Cowboy will be included and started automatically. This is not enough however, as Cowboy doesn't do anything by default. We still need to tell Cowboy to listen for connections.</p>
-
-<h2 id="listening_for_connections">Listening for connections</h2>
-
-<p>We will do this when our application starts. It's a two step process. First we need to define and compile the dispatch list, a list of routes that Cowboy will use to map requests to handler modules. Then we tell Cowboy to listen for connections.</p>
-
-<p>Open the <code>src/hello_erlang_app.erl</code> file and add the necessary code to the <code>start/2</code> function to make it look like this:</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-start(_Type, _Args) ->
-	Dispatch = cowboy_router:compile([
-		{'_', [{"/", hello_handler, []}]}
-	]),
-	cowboy:start_http(my_http_listener, 100, [{port, 8080}],
-		[{env, [{dispatch, Dispatch}]}]
-	),
-	hello_erlang_sup:start_link().
-]]></script>
-
-<p>The dispatch list is explained in great details in the <a href="/docs/en/cowboy/1.0/guide/routing">Routing</a> chapter. For this tutorial we map the path <code>/</code> to the handler module <code>hello_handler</code>. This module doesn't exist yet, we still have to write it.</p>
-
-<p>If you build the release, start it and open <a href="http://localhost:8080">http://localhost:8080</a> now, you will get an error because the module is missing. Any other URL, like <a href="http://localhost:8080/test">http://localhost:8080/test</a>, will result in a 404 error.</p>
-
-<h2 id="handling_requests">Handling requests</h2>
-
-<p>Cowboy features different kinds of handlers, including REST and Websocket handlers. For this tutorial we will use a plain HTTP handler.</p>
-
-<p>First, let's generate a handler from a template.</p>
-
-<script type="syntaxhighlighter" class="brush: bash"><![CDATA[
-$ make new t=cowboy_http n=hello_handler
-]]></script>
-
-<p>You can then open the <code>src/hello_handler.erl</code> file and modify the <code>handle/2</code> function like this to send a reply.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-handle(Req, State=#state{}) ->
-	{ok, Req2} = cowboy_req:reply(200,
-		[{<<"content-type">>, <<"text/plain">>}],
-		<<"Hello Erlang!">>,
-		Req),
-	{ok, Req2, State}.
-]]></script>
-
-<p>What the above code does is send a <code>200 OK</code> reply, with the <code>content-type</code> header set to <code>text/plain</code> and the response body set to <code>Hello Erlang!</code>.</p>
-
-<p>If you build the release, start it and open <a href="http://localhost:8080">http://localhost:8080</a> in your browser, you should get a nice <code>Hello Erlang!</code> displayed!</p>

-<h1 class="lined-header"><span>Hooks</span></h1>
-
-<p>Cowboy provides two hooks. <code>onrequest</code> is called once the request line and headers have been received. <code>onresponse</code> is called just before sending the response.</p>
-
-<h2 id="onrequest">Onrequest</h2>
-
-<p>The <code>onrequest</code> hook is called as soon as Cowboy finishes fetching the request headers. It occurs before any other processing, including routing. It can be used to perform any modification needed on the request object before continuing with the processing. If a reply is sent inside this hook, then Cowboy will move on to the next request, skipping any subsequent handling.</p>
-
-<p>This hook is a function that takes a request object as argument, and returns a request object. This function MUST NOT crash. Cowboy will not send any reply if a crash occurs in this function.</p>
-
-<p>You can specify the <code>onrequest</code> hook when creating the listener, inside the request options.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-cowboy:start_http(my_http_listener, 100,
-    [{port, 8080}],
-    [
-        {env, [{dispatch, Dispatch}]},
-        {onrequest, fun ?MODULE:debug_hook/1}
-    ]
-).
-]]></script>
-
-<p>The following hook function prints the request object everytime a request is received. This can be useful for debugging, for example.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-debug_hook(Req) ->
-    erlang:display(Req),
-    Req.
-]]></script>
-
-<p>Make sure to always return the last request object obtained.</p>
-
-<h2 id="onresponse">Onresponse</h2>
-
-<p>The <code>onresponse</code> hook is called right before sending the response to the socket. It can be used for the purposes of logging responses, or for modifying the response headers or body. The best example is providing custom error pages.</p>
-
-<p>Note that like the <code>onrequest</code> hook, this function MUST NOT crash. Cowboy may or may not send a reply if this function crashes. If a reply is sent, the hook MUST explicitly provide all headers that are needed.</p>
-
-<p>You can specify the <code>onresponse</code> hook when creating the listener.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-cowboy:start_http(my_http_listener, 100,
-    [{port, 8080}],
-    [
-        {env, [{dispatch, Dispatch}]},
-        {onresponse, fun ?MODULE:custom_404_hook/4}
-    ]
-).
-]]></script>
-
-<p>The following hook function will provide a custom body for 404 errors when it has not been provided before, and will let Cowboy proceed with the default response otherwise.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-custom_404_hook(404, Headers, <<>>, Req) ->
-    Body = <<"404 Not Found.">>,
-    Headers2 = lists:keyreplace(<<"content-length">>, 1, Headers,
-        {<<"content-length">>, integer_to_list(byte_size(Body))}),
-    {ok, Req2} = cowboy_req:reply(404, Headers2, Body, Req),
-    Req2;
-custom_404_hook(_, _, _, Req) ->
-    Req.
-]]></script>
-
-<p>Again, make sure to always return the last request object obtained.</p>

-<h1 class="lined-header"><span>Handling plain HTTP requests</span></h1>
-
-<p>The simplest way to handle a request is by writing a plain HTTP handler. It is modeled after Erlang/OTP's gen_server behaviour, although simplified, as Cowboy will simply call the three callbacks sequentially.</p>
-
-<h2 id="initialization">Initialization</h2>
-
-<p>The first callback, <code>init/3</code>, is common to all handlers, as it is used to identify the type of handler. Plain HTTP handlers just return <code>ok</code>.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-init(_Type, Req, _Opts) ->
-    {ok, Req, no_state}.
-]]></script>
-
-<p>This function receives the name of the transport and protocol modules used for processing the request. They can be used to quickly dismiss requests. For example the following handler will crash when accessed using TCP instead of SSL.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-init({ssl, _}, Req, _Opts) ->
-    {ok, Req, no_state}.
-]]></script>
-
-<p>This function also receives the options associated with this route that you configured previously. If your handler does not use options, then it is recommended you match the value <code>[]</code> directly to quickly detect configuration errors.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-init(_Type, Req, []) ->
-    {ok, Req, no_state}.
-]]></script>
-
-<p>You do not need to validate the options unless they are user configured. If they are, and there's a configuration error, you may choose to crash. For example, this will crash if the required <code>lang</code> option is not found.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-init(_Type, Req, Opts) ->
-    {_, _Lang} = lists:keyfind(lang, 1, Opts),
-    {ok, Req, no_state}.
-]]></script>
-
-<p>If your users are unlikely to figure out the issue without explanations, then you should send a more meaningful error back to the user. Since we already replied to the user, there's no need for us to continue with the handler code, so we use the <code>shutdown</code> return value to stop early.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-init(_Type, Req, Opts) ->
-    case lists:keyfind(lang, 1, Opts) of
-        false ->
-            {ok, Req2} = cowboy_req:reply(500, [
-                {<<"content-type">>, <<"text/plain">>}
-            ], "Missing option 'lang'.", Req),
-            {shutdown, Req2, no_state};
-        _ ->
-            {ok, Req, no_state}
-    end.
-]]></script>
-
-<p>Once the options have been validated, we can use them safely. So we need to pass them onward to the rest of the handler. That's what the third element of the return tuple, the state, is for.</p>
-
-<p>We recommend that you create a state record for this. The record will make your handler code clearer and will allow you to better use Dialyzer for type checking.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
--record(state, {
-    lang :: en | fr
-    %% More fields here.
-}).
-
-init(_Type, Req, Opts) ->
-    {_, Lang} = lists:keyfind(lang, 1, Opts),
-    {ok, Req, #state{lang=Lang}}.
-]]></script>
-
-<h2 id="handling_the_request">Handling the request</h2>
-
-<p>The second callback, <code>handle/2</code>, is specific to plain HTTP handlers. It's where you, wait for it, handle the request.</p>
-
-<p>A handle function that does nothing would look like this:</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-handle(Req, State) ->
-    {ok, Req, State}.
-]]></script>
-
-<p>There's no other return value. To obtain information about the request, or send a response, you would use the Req object here. The Req object is documented in its own chapter.</p>
-
-<p>The following handle function will send a fairly original response.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-handle(Req, State) ->
-    {ok, Req2} = cowboy_req:reply(200, [
-        {<<"content-type">>, <<"text/plain">>}
-    ], <<"Hello World!">>, Req),
-    {ok, Req2, State}.
-]]></script>
-
-<h2 id="cleaning_up">Cleaning up</h2>
-
-<p>The third and last callback, <code>terminate/3</code>, will most likely be empty in your handler.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-terminate(_Reason, Req, State) ->
-    ok.
-]]></script>
-
-<p>This callback is strictly reserved for any required cleanup. You cannot send a response from this function. There is no other return value.</p>
-
-<p>If you used the process dictionary, timers, monitors or may be receiving messages, then you can use this function to clean them up, as Cowboy might reuse the process for the next keep-alive request.</p>
-
-<p>The chances of any of this happening in your handler are pretty thin however. The use of the process dictionary is discouraged in Erlang code in general. And if you need to use timers, monitors or to receive messages, you are better off with a loop handler, a different kind of handler meant specifically for this use.</p>
-
-<p>This function is still available should you need it. It will always be called.</p>

-<h1 class="lined-header"><span>The life of a request</span></h1>
-
-<p>This chapter explains the different steps a request goes through until a response is sent, along with details of the Cowboy implementation.</p>
-
-<h2 id="request/response">Request/response</h2>
-
-<p>As you already know, HTTP clients connect to the server and send a request for a resource; the server then sends a response containing the resource if it could obtain it.</p>
-
-<p>Before the server can send the resource, however, it needs to perform many different operations to read the request, find the resource, prepare the response being sent and often other related operations the user can add like writing logs.</p>
-
-<p>Requests take the following route in Cowboy:</p>
-
-<p><img title="HTTP request/response flowchart" src="/docs/en/cowboy/1.0/guide/http_req_resp.png"/></p>
-
-<p>This shows the default middlewares, but they may be configured differently in your setup. The dark green indicates the points where you can hook your own code, the light green is the Cowboy code that you can of course configure as needed.</p>
-
-<p>The <code>acceptor</code> is the part of the server that accepts the connection and create an Erlang process to handle it. The <code>parser</code> then starts reading from the socket and handling requests as they come until the socket is closed.</p>
-
-<p>A response may be sent at many different points in the life of the request. If Cowboy can't parse the request, it gives up with an error response. If the router can't find the resource, it sends a not found error. Your own code can of course send a response at any time.</p>
-
-<p>When a response is sent, you can optionally modify it or act upon it by enabling the <code>onresponse</code> hook. By default the response is sent directly to the client.</p>
-
-<h2 id="and_then?">And then?</h2>
-
-<p>Behavior depends on what protocol is in use.</p>
-
-<p>HTTP/1.0 can only process one request per connection, so Cowboy will close the connection immediately after it sends the response.</p>
-
-<p>HTTP/1.1 allows the client to request that the server keeps the connection alive. This mechanism is described in the next section.</p>
-
-<p>SPDY is designed to allow sending multiple requests asynchronously on the same connection. Details on what this means for your application is described in this chapter.</p>
-
-<h2 id="keep-alive_(http/1.1)">Keep-alive (HTTP/1.1)</h2>
-
-<p>With HTTP/1.1, the connection may be left open for subsequent requests to come. This mechanism is called <code>keep-alive</code>.</p>
-
-<p>When the client sends a request to the server, it includes a header indicating whether it would like to leave the socket open. The server may or may not accept, indicating its choice by sending the same header in the response.</p>
-
-<p>Cowboy will include this header automatically in all responses to HTTP/1.1 requests. You can however force the closing of the socket if you want. When Cowboy sees you want to send a <code>connection: close</code> header, it will not override it and will close the connection as soon as the reply is sent.</p>
-
-<p>This snippet will force Cowboy to close the connection.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{ok, Req2} = cowboy_req:reply(200, [
-    {<<"connection">>, <<"close">>},
-], <<"Closing the socket in 3.. 2.. 1..">>, Req).
-]]></script>
-
-<p>Cowboy will only accept a certain number of new requests on the same connection. By default it will run up to 100 requests. This number can be changed by setting the <code>max_keepalive</code> configuration value when starting an HTTP listener.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-cowboy:start_http(my_http_listener, 100, [{port, 8080}], [
-        {env, [{dispatch, Dispatch}]},
-        {max_keepalive, 5}
-]).
-]]></script>
-
-<p>Cowboy implements the keep-alive mechanism by reusing the same process for all requests. This allows Cowboy to save memory. This works well because most code will not have any side effect impacting subsequent requests. But it also means you need to clean up if you do have code with side effects. The <code>terminate/3</code> function can be used for this purpose.</p>
-
-<h2 id="pipelining_(http/1.1)">Pipelining (HTTP/1.1)</h2>
-
-<p>While HTTP is designed as a sequential protocol, with the client sending a request and then waiting for the response from the server, nothing prevents the client from sending more requests to the server without waiting for the response, due to how sockets work. The server still handles the requests sequentially and sends the responses in the same order.</p>
-
-<p>This mechanism is called pipelining. It allows reducing latency when a client needs to request many resources at the same time. This is used by browsers when requesting static files for example.</p>
-
-<p>This is handled automatically by the server.</p>
-
-<h2 id="asynchronous_requests_(spdy)">Asynchronous requests (SPDY)</h2>
-
-<p>In SPDY, the client can send a request at any time. And the server can send a response at any time too.</p>
-
-<p>This means for example that the client does not need to wait for a request to be fully sent to send another, it is possible to interleave a request with the request body of another request. The same is true with responses. Responses may also be sent in a different order.</p>
-
-<p>Because requests and responses are fully asynchronous, Cowboy creates a new process for each request, and these processes are managed by another process that handles the connection itself.</p>
-
-<p>SPDY servers may also decide to send resources to the client before the client requests them. This is especially useful for sending static files associated with the HTML page requested, as this reduces the latency of the overall response. Cowboy does not support this particular mechanism at this point, however.</p>

-
-<p>Cowboy is a small, fast and modular HTTP server written in Erlang.</p>
-
-<p>Cowboy aims to provide a complete HTTP stack, including its derivatives SPDY, Websocket and REST. Cowboy currently supports HTTP/1.0, HTTP/1.1, Websocket (all implemented drafts + standard) and Webmachine-based REST.</p>
-
-<p>Cowboy is a high quality project. It has a small code base, is very efficient (both in latency and memory use) and can easily be embedded in another application.</p>
-
-<p>Cowboy is clean Erlang code. It includes hundreds of tests and its code is fully compliant with the Dialyzer. It is also well documented and features both a Function Reference and a User Guide.</p>
-
-<h2 id="prerequisites">Prerequisites</h2>
-
-<p>No Erlang knowledge is required for reading this guide. The reader will be introduced to Erlang concepts and redirected to reference material whenever necessary.</p>
-
-<p>Knowledge of the HTTP protocol is recommended but not required, as it will be detailed throughout the guide.</p>
-
-<h2 id="supported_platforms">Supported platforms</h2>
-
-<p>Cowboy is tested and supported on Linux.</p>
-
-<p>Cowboy has been reported to work on other platforms, but we make no guarantee that the experience will be safe and smooth. You are advised to perform the necessary testing and security audits prior to deploying on other platforms.</p>
-
-<p>Cowboy is developed for Erlang/OTP R16B01, R16B02, R16B03-1, 17.0 and 17.1.2.</p>
-
-<p>Cowboy may be compiled on other Erlang versions with small source code modifications but there is no guarantee that it will work as expected.</p>
-
-<h2 id="versioning">Versioning</h2>
-
-<p>Cowboy uses <a href="http://semver.org/">Semantic Versioning 2.0.0</a>.</p>
-
-<h2 id="conventions">Conventions</h2>
-
-<p>In the HTTP protocol, the method name is case sensitive. All standard method names are uppercase.</p>
-
-<p>Header names are case insensitive. Cowboy converts all the request header names to lowercase, and expects your application to provide lowercase header names in the response.</p>
-
-<p>The same applies to any other case insensitive value.</p>

-<h1 class="lined-header"><span>Loop handlers</span></h1>
-
-<p>Loop handlers are a special kind of HTTP handlers used when the response can not be sent right away. The handler enters instead a receive loop waiting for the right message before it can send a response.</p>
-
-<p>Loop handlers are used for requests where a response might not be immediately available, but where you would like to keep the connection open for a while in case the response arrives. The most known example of such practice is known as long-polling.</p>
-
-<p>Loop handlers can also be used for requests where a response is partially available and you need to stream the response body while the connection is open. The most known example of such practice is known as server-sent events.</p>
-
-<p>While the same can be accomplished using plain HTTP handlers, it is recommended to use loop handlers because they are well-tested and allow using built-in features like hibernation and timeouts.</p>
-
-<p>Loop handlers essentially wait for one or more Erlang messages and feed these messages to the <code>info/3</code> callback. It also features the <code>init/3</code> and <code>terminate/3</code> callbacks which work the same as for plain HTTP handlers.</p>
-
-<h2 id="initialization">Initialization</h2>
-
-<p>The <code>init/3</code> function must return a <code>loop</code> tuple to enable loop handler behavior. This tuple may optionally contain a timeout value and/or the atom <code>hibernate</code> to make the process enter hibernation until a message is received.</p>
-
-<p>This snippet enables the loop handler.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-init(_Type, Req, _Opts) ->
-    {loop, Req, undefined_state}.
-]]></script>
-
-<p>However it is largely recommended that you set a timeout value. The next example sets a timeout value of 30s and also makes the process hibernate.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-init(_Type, Req, _Opts) ->
-    {loop, Req, undefined_state, 30000, hibernate}.
-]]></script>
-
-<h2 id="receive_loop">Receive loop</h2>
-
-<p>Once initialized, Cowboy will wait for messages to arrive in the process' mailbox. When a message arrives, Cowboy calls the <code>info/3</code> function with the message, the Req object and the handler's state.</p>
-
-<p>The following snippet sends a reply when it receives a <code>reply</code> message from another process, or waits for another message otherwise.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-info({reply, Body}, Req, State) ->
-    {ok, Req2} = cowboy_req:reply(200, [], Body, Req),
-    {ok, Req2, State};
-info(_Msg, Req, State) ->
-    {loop, Req, State, hibernate}.
-]]></script>
-
-<p>Do note that the <code>reply</code> tuple here may be any message and is simply an example.</p>
-
-<p>This callback may perform any necessary operation including sending all or parts of a reply, and will subsequently return a tuple indicating if more messages are to be expected.</p>
-
-<p>The callback may also choose to do nothing at all and just skip the message received.</p>
-
-<p>If a reply is sent, then the <code>ok</code> tuple should be returned. This will instruct Cowboy to end the request.</p>
-
-<p>Otherwise a <code>loop</code> tuple should be returned.</p>
-
-<h2 id="streaming_loop">Streaming loop</h2>
-
-<p>Another common case well suited for loop handlers is streaming data received in the form of Erlang messages. This can be done by initiating a chunked reply in the <code>init/3</code> callback and then using <code>cowboy_req:chunk/2</code> every time a message is received.</p>
-
-<p>The following snippet does exactly that. As you can see a chunk is sent every time a <code>chunk</code> message is received, and the loop is stopped by sending an <code>eof</code> message.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-init(_Type, Req, _Opts) ->
-	{ok, Req2} = cowboy_req:chunked_reply(200, [], Req),
-    {loop, Req2, undefined_state}.
-
-info(eof, Req, State) ->
-    {ok, Req, State};
-info({chunk, Chunk}, Req, State) ->
-    ok = cowboy_req:chunk(Chunk, Req),
-    {loop, Req, State};
-info(_Msg, Req, State) ->
-    {loop, Req, State}.
-]]></script>
-
-<h2 id="cleaning_up">Cleaning up</h2>
-
-<p>It is recommended that you set the connection header to <code>close</code> when replying, as this process may be reused for a subsequent request.</p>
-
-<p>Please refer to the <a href="/docs/en/cowboy/1.0/guide/http_handlers">HTTP handlers chapter</a> for general instructions about cleaning up.</p>
-
-<h2 id="timeout">Timeout</h2>
-
-<p>By default Cowboy will not attempt to close the connection if there is no activity from the client. This is not always desirable, which is why you can set a timeout. Cowboy will close the connection if no data was received from the client after the configured time. The timeout only needs to be set once and can't be modified afterwards.</p>
-
-<p>Because the request may have had a body, or may be followed by another request, Cowboy is forced to buffer all data it receives. This data may grow to become too large though, so there is a configurable limit for it. The default buffer size is of 5000 bytes, but it may be changed by setting the <code>loop_max_buffer</code> middleware environment value.</p>
-
-<h2 id="hibernate">Hibernate</h2>
-
-<p>To save memory, you may hibernate the process in between messages received. This is done by returning the atom <code>hibernate</code> as part of the <code>loop</code> tuple callbacks normally return. Just add the atom at the end and Cowboy will hibernate accordingly.</p>

-<h1 class="lined-header"><span>Middlewares</span></h1>
-
-<p>Cowboy delegates the request processing to middleware components. By default, two middlewares are defined, for the routing and handling of the request, as is detailed in most of this guide.</p>
-
-<p>Middlewares give you complete control over how requests are to be processed. You can add your own middlewares to the mix or completely change the chain of middlewares as needed.</p>
-
-<p>Cowboy will execute all middlewares in the given order, unless one of them decides to stop processing.</p>
-
-<h2 id="usage">Usage</h2>
-
-<p>Middlewares only need to implement a single callback: <code>execute/2</code>. It is defined in the <code>cowboy_middleware</code> behavior.</p>
-
-<p>This callback has two arguments. The first is the <code>Req</code> object. The second is the environment.</p>
-
-<p>Middlewares can return one of four different values:</p>
-
-<ul>
-<li><code>{ok, Req, Env}</code> to continue the request processing</li>
-<li><code>{suspend, Module, Function, Args}</code> to hibernate</li>
-<li><code>{halt, Req}</code> to stop processing and move on to the next request</li>
-<li><code>{error, StatusCode, Req}</code> to reply an error and close the socket</li>
-</ul>
-
-<p>Of note is that when hibernating, processing will resume on the given MFA, discarding all previous stacktrace. Make sure you keep the <code>Req</code> and <code>Env</code> in the arguments of this MFA for later use.</p>
-
-<p>If an error happens during middleware processing, Cowboy will not try to send an error back to the socket, the process will just crash. It is up to the middleware to make sure that a reply is sent if something goes wrong.</p>
-
-<h2 id="configuration">Configuration</h2>
-
-<p>The middleware environment is defined as the <code>env</code> protocol option. In the previous chapters we saw it briefly when we needed to pass the routing information. It is a list of tuples with the first element being an atom and the second any Erlang term.</p>
-
-<p>Two values in the environment are reserved:</p>
-
-<ul>
-<li><code>listener</code> contains the name of the listener</li>
-<li><code>result</code> contains the result of the processing</li>
-</ul>
-
-<p>The <code>listener</code> value is always defined. The <code>result</code> value can be set by any middleware. If set to anything other than <code>ok</code>, Cowboy will not process any subsequent requests on this connection.</p>
-
-<p>The middlewares that come with Cowboy may define or require other environment values to perform.</p>
-
-<p>You can update the environment by calling the <code>cowboy:set_env/3</code> convenience function, adding or replacing a value in the environment.</p>
-
-<h2 id="routing_middleware">Routing middleware</h2>
-
-<p>The routing middleware requires the <code>dispatch</code> value. If routing succeeds, it will put the handler name and options in the <code>handler</code> and <code>handler_opts</code> values of the environment, respectively.</p>
-
-<h2 id="handler_middleware">Handler middleware</h2>
-
-<p>The handler middleware requires the <code>handler</code> and <code>handler_opts</code> values. It puts the result of the request handling into <code>result</code>.</p>

-<h1 class="lined-header"><span>The modern Web</span></h1>
-
-<p>Let's take a look at various technologies from the beginnings of the Web up to this day, and get a preview of what's coming next.</p>
-
-<p>Cowboy is compatible with all the technology cited in this chapter except of course HTTP/2.0 which has no implementation in the wild at the time of writing.</p>
-
-<h2 id="the_prehistoric_web">The prehistoric Web</h2>
-
-<p>HTTP was initially created to serve HTML pages and only had the GET method for retrieving them. This initial version is documented and is sometimes called HTTP/0.9. HTTP/1.0 defined the GET, HEAD and POST methods, and was able to send data with POST requests.</p>
-
-<p>HTTP/1.0 works in a very simple way. A TCP connection is first established to the server. Then a request is sent. Then the server sends a response back and closes the connection.</p>
-
-<p>Suffice to say, HTTP/1.0 is not very efficient. Opening a TCP connection takes some time, and pages containing many assets load much slower than they could because of this.</p>
-
-<p>Most improvements done in recent years focused on reducing this load time and reducing the latency of the requests.</p>
-
-<h2 id="http/1.1">HTTP/1.1</h2>
-
-<p>HTTP/1.1 quickly followed and added a keep-alive mechanism to allow using the same connection for many requests, as well as streaming capabilities, allowing an endpoint to send a body in well defined chunks.</p>
-
-<p>HTTP/1.1 defines the OPTIONS, GET, HEAD, POST, PUT, DELETE, TRACE and CONNECT methods. The PATCH method was added in more recent years. It also improves the caching capabilities with the introduction of many headers.</p>
-
-<p>HTTP/1.1 still works like HTTP/1.0 does, except the connection can be kept alive for subsequent requests. This however allows clients to perform what is called as pipelining: sending many requests in a row, and then processing the responses which will be received in the same order as the requests.</p>
-
-<h2 id="rest">REST</h2>
-
-<p>The design of HTTP/1.1 was influenced by the REST architectural style. REST, or REpresentational State Transfer, is a style of architecture for loosely connected distributed systems.</p>
-
-<p>REST defines constraints that systems must obey to in order to be RESTful. A system which doesn't follow all the constraints cannot be considered RESTful.</p>
-
-<p>REST is a client-server architecture with a clean separation of concerns between the client and the server. They communicate by referencing resources. Resources can be identified, but also manipulated. A resource representation has a media type and information about whether it can be cached and how. Hypermedia determines how resources are related and how they can be used. REST is also stateless. All requests contain the complete information necessary to perform the action.</p>
-
-<p>HTTP/1.1 defines all the methods, headers and semantics required to implement RESTful systems.</p>
-
-<p>REST is most often used when designing web application APIs which are generally meant to be used by executable code directly.</p>
-
-<h2 id="xmlhttprequest">XmlHttpRequest</h2>
-
-<p>Also know as AJAX, this technology allows Javascript code running on a web page to perform asynchronous requests to the server. This is what started the move from static websites to dynamic web applications.</p>
-
-<p>XmlHttpRequest still performs HTTP requests under the hood, and then waits for a response, but the Javascript code can continue to run until the response arrives. It will then receive the response through a callback previously defined.</p>
-
-<p>This is of course still requests initiated by the client, the server still had no way of pushing data to the client on its own, so new technology appeared to allow that.</p>
-
-<h2 id="long-polling">Long-polling</h2>
-
-<p>Polling was a technique used to overcome the fact that the server cannot push data directly to the client. Therefore the client had to repeatedly create a connection, make a request, get a response, then try again a few seconds later. This is overly expensive and adds an additional delay before the client receives the data.</p>
-
-<p>Polling was necessary to implement message queues and other similar mechanisms, where a user must be informed of something when it happens, rather than when he refreshes the page next. A typical example would be a chat application.</p>
-
-<p>Long-polling was created to reduce the server load by creating less connections, but also to improve latency by getting the response back to the client as soon as it becomes available on the server.</p>
-
-<p>Long-polling works in a similar manner to polling, except the request will not get a response immediately. Instead the server leaves it open until it has a response to send. After getting the response, the client creates a new request and gets back to waiting.</p>
-
-<p>You probably guessed by now that long-polling is a hack, and like most hacks it can suffer from unforeseen issues, in this case it doesn't always play well with proxies.</p>
-
-<h2 id="html5">HTML5</h2>
-
-<p>HTML5 is, of course, the HTML version after HTML4. But HTML5 emerged to solve a specific problem: dynamic web applications.</p>
-
-<p>HTML was initially created to write web pages which compose a website. But soon people and companies wanted to use HTML to write more and more complex websites, eventually known as web applications. They are for example your news reader, your email client in the browser, or your video streaming website.</p>
-
-<p>Because HTML wasn't enough, they started using proprietary solutions, often implemented using plug-ins. This wasn't perfect of course, but worked well enough for most people.</p>
-
-<p>However, the needs for a standard solution eventually became apparent. The browser needed to be able to play media natively. It needed to be able to draw anything. It needed an efficient way of streaming events to the server, but also receiving events from the server.</p>
-
-<p>The solution went on to become HTML5. At the time of writing it is being standardized.</p>
-
-<h2 id="eventsource">EventSource</h2>
-
-<p>EventSource, sometimes also called Server-Sent Events, is a technology allowing servers to push data to HTML5 applications.</p>
-
-<p>EventSource is one-way communication channel from the server to the client. The client has no means to talk to the server other than by using HTTP requests.</p>
-
-<p>It consists of a Javascript object allowing setting up an EventSource connection to the server, and a very small protocol for sending events to the client on top of the HTTP/1.1 connection.</p>
-
-<p>EventSource is a lightweight solution that only works for UTF-8 encoded text data. Binary data and text data encoded differently are not allowed by the protocol. A heavier but more generic approach can be found in Websocket.</p>
-
-<h2 id="websocket">Websocket</h2>
-
-<p>Websocket is a protocol built on top of HTTP/1.1 that provides a two-ways communication channel between the client and the server. Communication is asynchronous and can occur concurrently.</p>
-
-<p>It consists of a Javascript object allowing setting up a Websocket connection to the server, and a binary based protocol for sending data to the server or the client.</p>
-
-<p>Websocket connections can transfer either UTF-8 encoded text data or binary data. The protocol also includes support for implementing a ping/pong mechanism, allowing the server and the client to have more confidence that the connection is still alive.</p>
-
-<p>A Websocket connection can be used to transfer any kind of data, small or big, text or binary. Because of this Websocket is sometimes used for communication between systems.</p>
-
-<h2 id="spdy">SPDY</h2>
-
-<p>SPDY is an attempt to reduce page loading time by opening a single connection per server, keeping it open for subsequent requests, and also by compressing the HTTP headers to reduce the size of requests.</p>
-
-<p>SPDY is compatible with HTTP/1.1 semantics, and is actually just a different way of performing HTTP requests and responses, by using binary frames instead of a text-based protocol. SPDY also allows the server to send extra responses following a request. This is meant to allow sending the resources associated with the request before the client requests them, saving latency when loading websites.</p>
-
-<p>SPDY is an experiment that has proven successful and is used as the basis for the HTTP/2.0 standard.</p>
-
-<p>Browsers make use of TLS Next Protocol Negotiation to upgrade to a SPDY connection seamlessly if the protocol supports it.</p>
-
-<p>The protocol itself has a few shortcomings which are being fixed in HTTP/2.0.</p>
-
-<h2 id="http/2.0">HTTP/2.0</h2>
-
-<p>HTTP/2.0 is the long-awaited update to the HTTP/1.1 protocol. It is based on SPDY although a lot has been improved at the time of writing.</p>
-
-<p>HTTP/2.0 is an asynchronous two-ways communication channel between two endpoints.</p>
-
-<p>It is planned to be ready late 2014.</p>

-<h1 class="lined-header"><span>Introduction to multipart</span></h1>
-
-<p>Multipart originates from MIME, an Internet standard that extends the format of emails. Multipart messages are a container for parts of any content-type.</p>
-
-<p>For example, a multipart message may have a part containing text and a second part containing an image. This is what allows you to attach files to emails.</p>
-
-<p>In the context of HTTP, multipart is most often used with the <code>multipart/form-data</code> content-type. This is the content-type you have to use when you want browsers to be allowed to upload files through HTML forms.</p>
-
-<p>Multipart is of course not required for uploading files, it is only required when you want to do so through HTML forms.</p>
-
-<h2 id="structure">Structure</h2>
-
-<p>A multipart message is a list of parts. Parts may contain either a multipart message or a non-multipart content-type. This allows parts to be arranged in a tree structure, although this is a rare case as far as the Web is concerned.</p>
-
-<h2 id="form-data">Form-data</h2>
-
-<p>In the normal case, when a form is submitted, the browser will use the <code>application/x-www-form-urlencoded</code> content-type. This type is just a list of keys and values and is therefore not fit for uploading files.</p>
-
-<p>That's where the <code>multipart/form-data</code> content-type comes in. When the form is configured to use this content-type, the browser will use one part of the message for each form field. This means that a file input field will be sent in its own part, but the same applies to all other kinds of fields.</p>
-
-<p>A form with a text input, a file input and a select choice box will result in a multipart message with three parts, one for each field.</p>
-
-<p>The browser does its best to determine the content-type of the files it sends this way, but you should not rely on it for determining the contents of the file. Proper investigation of the contents is recommended.</p>

-
-<p>You can read and parse multipart messages using the Req object directly.</p>
-
-<p>Cowboy defines two functions that allows you to get information about each part and read their contents.</p>
-
-<h2 id="checking_the_content-type">Checking the content-type</h2>
-
-<p>While there is a variety of multipart messages, the most common on the Web is <code>multipart/form-data</code>. It's the type of message being sent when an HTML form allows uploading files.</p>
-
-<p>You can quickly figure out if a multipart message has been sent by parsing the <code>content-type</code> header.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{ok, {<<"multipart">>, <<"form-data">>, _}, Req2}
-    = cowboy_req:parse_header(<<"content-type">>, Req).
-]]></script>
-
-<h2 id="reading_a_multipart_message">Reading a multipart message</h2>
-
-<p>To read a message you have to iterate over all its parts. Then, for each part, you can inspect its headers and read its body.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-multipart(Req) ->
-    case cowboy_req:part(Req) of
-        {ok, _Headers, Req2} ->
-            {ok, _Body, Req3} = cowboy_req:part_body(Req2),
-            multipart(Req3);
-        {done, Req2} ->
-            Req2
-    end.
-]]></script>
-
-<p>Parts do not have a size limit. When a part body is too big, Cowboy will return what it read so far and allow you to continue if you wish to do so.</p>
-
-<p>The function <code>cow_multipart:form_data/1</code> can be used to quickly obtain information about a part from a <code>multipart/form-data</code> message. This function will tell you if the part is for a normal field or if it is a file being uploaded.</p>
-
-<p>This can be used for example to allow large part bodies for files but crash when a normal field is too large.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-multipart(Req) ->
-    case cowboy_req:part(Req) of

-    end.
-]]></script>
-
-<p>By default the body chunk Cowboy will return is limited to 8MB. This can of course be overriden. Both functions can take a second argument, the same list of options that will be passed to <code>cowboy_req:body/2</code> function.</p>
-
-<h2 id="skipping_unwanted_parts">Skipping unwanted parts</h2>
-
-<p>If you do not want to read a part's body, you can skip it. Skipping is easy. If you do not call the function to read the part's body, Cowboy will automatically skip it when you request the next part.</p>
-
-<p>The following snippet reads all part headers and skips all bodies:</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-multipart(Req) ->
-    case cowboy_req:part(Req) of
-        {ok, _Headers, Req2} ->
-            multipart(Req2);
-        {done, Req2} ->
-            Req2
-    end.
-]]></script>
-
-<p>Similarly, if you start reading the body and it ends up being too big, you can simply continue with the next part, Cowboy will automatically skip what remains.</p>
-
-<p>Note that the skipping rate may not be adequate for your application. If you observe poor performance when skipping, you might want to consider manually skipping by calling the <code>cowboy_req:part_body/1</code> function directly.</p>
-
-<p>And if you started reading the message but decide that you do not need the remaining parts, you can simply stop reading entirely and Cowboy will automatically figure out what to do.</p>

-<h1 class="lined-header"><span>The Req object</span></h1>
-
-<p>The Req object is this variable that you will use to obtain information about a request, read the body of the request and send a response.</p>
-
-<h2 id="a_special_variable">A special variable</h2>
-
-<p>While we call it an "object", it is not an object in the OOP sense of the term. In fact it is completely opaque to you and the only way you can perform operations using it is by calling the functions from the <code>cowboy_req</code> module.</p>
-
-<p>Almost all the calls to the <code>cowboy_req</code> module will return an updated request object. Just like you would keep the updated <code>State</code> variable in a gen_server, you MUST keep the updated <code>Req</code> variable in a Cowboy handler. Cowboy will use this object to know whether a response has been sent when the handler has finished executing.</p>
-
-<p>The Req object allows accessing both immutable and mutable state. This means that calling some of the functions twice will not produce the same result. For example, when streaming the request body, the function will return the body by chunks, one at a time, until there is none left.</p>
-
-<p>It also caches the result of operations performed on the immutable state. That means that some calls will give a result much faster when called many times.</p>
-
-<h2 id="overview_of_the_cowboy_req_interface">Overview of the cowboy_req interface</h2>
-
-<p>The <code>cowboy_req</code> interface is divided in four groups of functions, each having a well defined return type signature common to the entire group.</p>
-
-<p>The first group, access functions, will always return <code>{Value, Req}</code>. The group includes all the following functions: <code>binding/{2,3}</code>, <code>bindings/1</code>, <code>body_length/1</code>, <code>cookie/{2,3}</code>, <code>cookies/1</code>, <code>header/{2,3}</code>, <code>headers/1</code>, <code>host/1</code>, <code>host_info/1</code>, <code>host_url/1</code>, <code>meta/{2,3}</code>, <code>method/1</code>, <code>path/1</code>, <code>path_info/1</code>, <code>peer/1</code>, <code>port/1</code>, <code>qs/1</code>, <code>qs_val/{2,3}</code>, <code>qs_vals/1</code>, <code>url/1</code>, <code>version/1</code>.</p>
-
-<p>The second group, question functions, will always return a <code>boolean()</code>. The group includes the following three functions: <code>has_body/1</code>, <code>has_resp_body/1</code>, <code>has_resp_header/2</code>.</p>
-
-<p>The third group contains the functions that manipulate the socket or perform operations that may legitimately fail. They may return <code>{Result, Req}</code>, <code>{Result, Value, Req}</code> or <code>{error, atom()}</code>. This includes the following functions: <code>body/{1,2}</code>, <code>body_qs/{1,2}</code>, <code>chunked_reply/{2,3}</code>, <code>parse_header/{2,3}</code>, <code>part/{1,2}</code>, <code>part_body/{1,2}</code> and <code>reply/{2,3,4}</code>. Finally, the group also includes the <code>chunk/2</code> and <code>continue/1</code> functions which always return <code>ok</code>.</p>
-
-<p>The final group modifies the Req object state without performing any immediate operations. As these functions can't fail, they always return a new <code>Req</code> directly. This includes the following functions: <code>compact/1</code>, <code>delete_resp_header/2</code>, <code>set_meta/3</code>, <code>set_resp_body/2</code>, <code>set_resp_body_fun/{2,3}</code>, <code>set_resp_cookie/4</code>, <code>set_resp_header/3</code>.</p>
-
-<p>This chapter covers most of the first group, plus a few other functions. The next few chapters cover cookies handling, reading the request body and sending a response.</p>
-
-<h2 id="request">Request</h2>
-
-<p>When a client performs a request, it first sends a few required values. They are sent differently depending on the protocol being used, but the intent is the same. They indicate to the server the type of action it wants to do and how to locate the resource to perform it on.</p>
-
-<p>The method identifies the action. Standard methods include GET, HEAD, OPTIONS, PATCH, POST, PUT, DELETE. Method names are case sensitive.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{Method, Req2} = cowboy_req:method(Req).
-]]></script>
-
-<p>The host, port and path parts of the URL identify the resource being accessed. The host and port information may not be available if the client uses HTTP/1.0.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{Host, Req2} = cowboy_req:host(Req),
-{Port, Req3} = cowboy_req:port(Req2),
-{Path, Req4} = cowboy_req:path(Req3).
-]]></script>
-
-<p>The version used by the client can of course also be obtained.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{Version, Req2} = cowboy_req:version(Req).
-]]></script>
-
-<p>Do note however that clients claiming to implement one version of the protocol does not mean they implement it fully, or even properly.</p>
-
-<h2 id="bindings">Bindings</h2>
-
-<p>After routing the request, bindings are available. Bindings are these parts of the host or path that you chose to extract when defining the routes of your application.</p>
-
-<p>You can fetch a single binding. The value will be <code>undefined</code> if the binding doesn't exist.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{Binding, Req2} = cowboy_req:binding(my_binding, Req).
-]]></script>
-
-<p>If you need a different value when the binding doesn't exist, you can change the default.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{Binding, Req2} = cowboy_req:binding(my_binding, Req, 42).
-]]></script>
-
-<p>You can also obtain all bindings in one call. They will be returned as a list of key/value tuples.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{AllBindings, Req2} = cowboy_req:bindings(Req).
-]]></script>
-
-<p>If you used <code>...</code> at the beginning of the route's pattern for the host, you can retrieve the matched part of the host. The value will be <code>undefined</code> otherwise.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{HostInfo, Req2} = cowboy_req:host_info(Req).
-]]></script>
-
-<p>Similarly, if you used <code>...</code> at the end of the route's pattern for the path, you can retrieve the matched part, or get <code>undefined</code> otherwise.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{PathInfo, Req2} = cowboy_req:path_info(Req).
-]]></script>
-
-<h2 id="query_string">Query string</h2>
-
-<p>The query string can be obtained directly.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{Qs, Req2} = cowboy_req:qs(Req).
-]]></script>
-
-<p>You can also requests only one value.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{QsVal, Req2} = cowboy_req:qs_val(<<"lang">>, Req).
-]]></script>
-
-<p>If that value is optional, you can define a default to simplify your task.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{QsVal, Req2} = cowboy_req:qs_val(<<"lang">>, Req, <<"en">>).
-]]></script>
-
-<p>Finally, you can obtain all query string values.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{AllValues, Req2} = cowboy_req:qs_vals(Req).
-]]></script>
-
-<h2 id="request_url">Request URL</h2>
-
-<p>You can reconstruct the full URL of the resource.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{URL, Req2} = cowboy_req:url(Req).
-]]></script>
-
-<p>You can also obtain only the base of the URL, excluding the path and query string.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{BaseURL, Req2} = cowboy_req:host_url(Req).
-]]></script>
-
-<h2 id="headers">Headers</h2>
-
-<p>Cowboy allows you to obtain the header values as string, or parsed into a more meaningful representation.</p>
-
-<p>This will get the string value of a header.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{HeaderVal, Req2} = cowboy_req:header(<<"content-type">>, Req).
-]]></script>
-
-<p>You can of course set a default in case the header is missing.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{HeaderVal, Req2}
-    = cowboy_req:header(<<"content-type">>, Req, <<"text/plain">>).
-]]></script>
-
-<p>And also obtain all headers.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{AllHeaders, Req2} = cowboy_req:headers(Req).
-]]></script>
-
-<p>To parse the previous header, simply call <code>parse_header/{2,3}</code> where you would call <code>header/{2,3}</code> otherwise. Note that the return value changes and includes the result of the operation as the first element of the returned tuple. A successful parse returns <code>ok</code>.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{ok, ParsedVal, Req2} = cowboy_req:parse_header(<<"content-type">>, Req).
-]]></script>
-
-<p>When Cowboy doesn't know how to parse the given header, the result of the operation will be <code>undefined</code> and the string value will be returned instead.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{undefined, HeaderVal, Req2}
-    = cowboy_req:parse_header(<<"unicorn-header">>, Req).
-]]></script>
-
-<p>When parsing fails, <code>{error, Reason}</code> is returned instead.</p>
-
-<p>You can of course define a default value. Note that the default value you specify here is the parsed value you'd like to get by default.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{ok, ParsedVal, Req2}
-    = cowboy_req:parse_header(<<"content-type">>, Req,
-    {<<"text">>, <<"plain">>, []}).
-]]></script>
-
-<p>The list of known headers and default values is defined in the manual. Also note that the result of parsing is cached, so calling this function multiple times for the same values will not have a significant performance impact.</p>
-
-<h2 id="meta">Meta</h2>
-
-<p>Cowboy will sometimes associate some meta information with the request. Built-in meta values are listed in the manual for their respective modules.</p>
-
-<p>This will get a meta value. The returned value will be <code>undefined</code> if it isn't defined.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{MetaVal, Req2} = cowboy_req:meta(websocket_version, Req).
-]]></script>
-
-<p>You can change the default value if needed.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{MetaVal, Req2} = cowboy_req:meta(websocket_version, Req, 13).
-]]></script>
-
-<p>You can also define your own meta values. The name must be an <code>atom()</code>.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-Req2 = cowboy_req:set_meta(the_answer, 42, Req).
-]]></script>
-
-<h2 id="peer">Peer</h2>
-
-<p>You can obtain the peer address and port number. This is not necessarily the actual IP and port of the client, but rather the one of the machine that connected to the server.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{{IP, Port}, Req2} = cowboy_req:peer(Req).
-]]></script>
-
-<h2 id="reducing_the_memory_footprint">Reducing the memory footprint</h2>
-
-<p>When you are done reading information from the request object and know you are not going to access it anymore, for example when using long-polling or Websocket, you can use the <code>compact/1</code> function to remove most of the data from the request object and free memory.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-Req2 = cowboy_req:compact(Req).
-]]></script>
-
-<p>You will still be able to send a reply if needed.</p>

-
-<h1 class="lined-header"><span>Reading the request body</span></h1>
-
-<p>The Req object also allows you to read the request body.</p>
-
-<p>Because the request body can be of any size, all body reading operations will only work once, as Cowboy will not cache the result of these operations.</p>
-
-<p>Cowboy will not attempt to read the body until you do. If handler execution ends without reading it, Cowboy will simply skip it.</p>
-
-<p>Cowboy provides different ways to read the request body. You can read it directly, stream it, but also read and parse in a single call for form urlencoded formats or multipart. All of these except multipart are covered in this chapter. Multipart is covered later on in the guide.</p>
-
-<h2 id="check_for_request_body">Check for request body</h2>
-
-<p>You can check whether a body was sent with the request.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-cowboy_req:has_body(Req).
-]]></script>
-
-<p>It will return <code>true</code> if there is a request body, and <code>false</code> otherwise.</p>
-
-<p>Note that it is generally safe to assume that a body is sent for <code>POST</code>, <code>PUT</code> and <code>PATCH</code> requests, without having to explicitly check for it.</p>
-
-<h2 id="request_body_length">Request body length</h2>
-
-<p>You can obtain the body length if it was sent with the request.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{Length, Req2} = cowboy_req:body_length(Req).
-]]></script>
-
-<p>The value returned will be <code>undefined</code> if the length couldn't be figured out from the request headers. If there's a body but no length is given, this means that the chunked transfer-encoding was used. You can read chunked bodies by using the stream functions.</p>
-
-<h2 id="reading_the_body">Reading the body</h2>
-
-<p>You can read the whole body directly in one call.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{ok, Body, Req2} = cowboy_req:body(Req).
-]]></script>
-
-<p>By default, Cowboy will attempt to read up to a size of 8MB. You can override this limit as needed.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{ok, Body, Req2} = cowboy_req:body(Req, [{length, 100000000}]).
-]]></script>
-
-<p>You can also disable it.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{ok, Body, Req2} = cowboy_req:body(Req, [{length, infinity}]).
-]]></script>
-
-<p>It is recommended that you do not disable it for public facing websites.</p>
-
-<p>If the body is larger than the limit, then Cowboy will return a <code>more</code> tuple instead, allowing you to stream it if you would like to.</p>
-
-<h2 id="streaming_the_body">Streaming the body</h2>
-
-<p>You can stream the request body by chunks.</p>
-
-<p>Cowboy returns a <code>more</code> tuple when there is more body to be read, and an <code>ok</code> tuple for the last chunk. This allows you to loop over all chunks.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-body_to_console(Req) ->
-    case cowboy_req:body(Req) of
-        {ok, Data, Req2} ->
-            io:format("~s", [Data]),
-            Req2;
-        {more, Data, Req2} ->
-            io:format("~s", [Data]),
-            body_to_console(Req2)
-    end.
-]]></script>
-
-<p>You can of course set the <code>length</code> option to configure the size of chunks.</p>
-
-<h2 id="rate_of_data_transmission">Rate of data transmission</h2>
-
-<p>You can control the rate of data transmission by setting options when calling body functions. This applies not only to the functions described in this chapter, but also to the multipart functions.</p>
-
-<p>The <code>read_length</code> option defines the maximum amount of data to be received from the socket at once, in bytes.</p>
-
-<p>The <code>read_timeout</code> option defines the time Cowboy waits before that amount is received, in milliseconds.</p>
-
-<h2 id="transfer_and_content_decoding">Transfer and content decoding</h2>
-
-<p>Cowboy will by default decode the chunked transfer-encoding if any. It will not decode any content-encoding by default.</p>
-
-<p>The first time you call a body function you can set the <code>transfer_decode</code> and <code>content_decode</code> options. If the body was already started being read these options are simply ignored.</p>
-
-<p>The following example shows how to set both options.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{ok, Req2} = cowboy_req:body(Req, [
-    {transfer_decode, fun transfer_decode/2, TransferState},
-    {content_decode, fun content_decode/1}
-]).
-]]></script>
-
-<h2 id="reading_a_form_urlencoded_body">Reading a form urlencoded body</h2>
-
-<p>You can directly obtain a list of key/value pairs if the body was sent using the application/x-www-form-urlencoded content-type.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{ok, KeyValues, Req2} = cowboy_req:body_qs(Req).
-]]></script>
-
-<p>You can then retrieve an individual value from that list.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{_, Lang} = lists:keyfind(lang, 1, KeyValues).
-]]></script>
-
-<p>You should not attempt to match on the list as the order of the values is undefined.</p>
-
-<p>By default Cowboy will reject bodies with a size above 64KB when using this function. You can override this limit by setting the <code>length</code> option.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{ok, KeyValues, Req2} = cowboy_req:body_qs(Req,
-    [{length, 2000000}]).
-]]></script>

-<h1 class="lined-header"><span>Designing a resource handler</span></h1>
-
-<p>This chapter aims to provide you with a list of questions you must answer in order to write a good resource handler. It is meant to be usable as a step by step guide.</p>
-
-<h2 id="the_service">The service</h2>
-
-<p>Can the service become unavailable, and when it does, can we detect it? For example database connectivity problems may be detected early. We may also have planned outages of all or parts of the system. Implement the <code>service_available</code> callback.</p>
-
-<p>What HTTP methods does the service implement? Do we need more than the standard OPTIONS, HEAD, GET, PUT, POST, PATCH and DELETE? Are we not using one of those at all? Implement the <code>known_methods</code> callback.</p>
-
-<h2 id="type_of_resource_handler">Type of resource handler</h2>
-
-<p>Am I writing a handler for a collection of resources, or for a single resource?</p>
-
-<p>The semantics for each of these are quite different. You should not mix collection and single resource in the same handler.</p>
-
-<h2 id="collection_handler">Collection handler</h2>
-
-<p>Skip this section if you are not doing a collection.</p>
-
-<p>Is the collection hardcoded or dynamic? For example if you use the route <code>/users</code> for the collection of users then the collection is hardcoded; if you use <code>/forums/:category</code> for the collection of threads then it isn't. When the collection is hardcoded you can safely assume the resource always exists.</p>
-
-<p>What methods should I implement?</p>
-
-<p>OPTIONS is used to get some information about the collection. It is recommended to allow it even if you do not implement it, as Cowboy has a default implementation built-in.</p>
-
-<p>HEAD and GET are used to retrieve the collection. If you allow GET, also allow HEAD as there's no extra work required to make it work.</p>
-
-<p>POST is used to create a new resource inside the collection. Creating a resource by using POST on the collection is useful when resources may be created before knowing their URI, usually because parts of it are generated dynamically. A common case is some kind of auto incremented integer identifier.</p>
-
-<p>The next methods are more rarely allowed.</p>
-
-<p>PUT is used to create a new collection (when the collection isn't hardcoded), or replace the entire collection.</p>
-
-<p>DELETE is used to delete the entire collection.</p>
-
-<p>PATCH is used to modify the collection using instructions given in the request body. A PATCH operation is atomic. The PATCH operation may be used for such things as reordering; adding, modifying or deleting parts of the collection.</p>
-
-<h2 id="single_resource_handler">Single resource handler</h2>
-
-<p>Skip this section if you are doing a collection.</p>
-
-<p>What methods should I implement?</p>
-
-<p>OPTIONS is used to get some information about the resource. It is recommended to allow it even if you do not implement it, as Cowboy has a default implementation built-in.</p>
-
-<p>HEAD and GET are used to retrieve the resource. If you allow GET, also allow HEAD as there's no extra work required to make it work.</p>
-
-<p>POST is used to update the resource.</p>
-
-<p>PUT is used to create a new resource (when it doesn't already exist) or replace the resource.</p>
-
-<p>DELETE is used to delete the resource.</p>
-
-<p>PATCH is used to modify the resource using instructions given in the request body. A PATCH operation is atomic. The PATCH operation may be used for adding, removing or modifying specific values in the resource.</p>
-
-<h2 id="the_resource">The resource</h2>
-
-<p>Following the above discussion, implement the <code>allowed_methods</code> callback.</p>
-
-<p>Does the resource always exist? If it may not, implement the <code>resource_exists</code> callback.</p>
-
-<p>Do I need to authenticate the client before they can access the resource? What authentication mechanisms should I provide? This may include form-based, token-based (in the URL or a cookie), HTTP basic, HTTP digest, SSL certificate or any other form of authentication. Implement the <code>is_authorized</code> callback.</p>
-
-<p>Do I need fine-grained access control? How do I determine that they are authorized access? Handle that in your <code>is_authorized</code> callback.</p>
-
-<p>Can access to a resource be forbidden regardless of access being authorized? A simple example of that is censorship of a resource. Implement the <code>forbidden</code> callback.</p>
-
-<p>Is there any constraints on the length of the resource URI? For example the URI may be used as a key in storage and may have a limit in length. Implement <code>uri_too_long</code>.</p>
-
-<h2 id="representations">Representations</h2>
-
-<p>What media types do I provide? If text based, what charsets are provided? What languages do I provide?</p>
-
-<p>Implement the mandatory <code>content_types_provided</code>. Prefix the callbacks with <code>to_</code> for clarity. For example <code>to_html</code> or <code>to_text</code>.</p>
-
-<p>Implement the <code>languages_provided</code> or <code>charsets_provided</code> callbacks if applicable.</p>
-
-<p>Is there any other header that may make the representation of the resource vary? Implement the <code>variances</code> callback.</p>
-
-<p>Depending on your choices for caching content, you may want to implement one or more of the <code>generate_etag</code>, <code>last_modified</code> and <code>expires</code> callbacks.</p>
-
-<p>Do I want the user or user agent to actively choose a representation available? Send a list of available representations in the response body and implement the <code>multiple_choices</code> callback.</p>
-
-<h2 id="redirections">Redirections</h2>
-
-<p>Do I need to keep track of what resources were deleted? For example you may have a mechanism where moving a resource leaves a redirect link to its new location. Implement the <code>previously_existed</code> callback.</p>
-
-<p>Was the resource moved, and is the move temporary? If it is explicitly temporary, for example due to maintenance, implement the <code>moved_temporarily</code> callback. Otherwise, implement the <code>moved_permanently</code> callback.</p>
-
-<h2 id="the_request">The request</h2>
-
-<p>Do we need to perform extra checks to make sure the request is valid? Cowboy will do many checks when receiving the request already, do we need more? Note that this only applies to the request-line and headers of the request, and not the body. Implement <code>malformed_request</code>.</p>
-
-<p>May there be a request body? Will I know its size? What's the maximum size of the request body I'm willing to accept? Implement <code>valid_entity_length</code>.</p>
-
-<p>Finally, take a look at the sections corresponding to the methods you are implementing.</p>
-
-<h2 id="options_method">OPTIONS method</h2>
-
-<p>Cowboy by default will send back a list of allowed methods. Do I need to add more information to the response? Implement the <code>options</code> method.</p>
-
-<h2 id="get_and_head_methods">GET and HEAD methods</h2>
-
-<p>If you implement the methods GET and/or HEAD, you must implement one <code>ProvideResource</code> callback for each content-type returned by the <code>content_types_provided</code> callback.</p>
-
-<h2 id="put,_post_and_patch_methods">PUT, POST and PATCH methods</h2>
-
-<p>If you implement the methods PUT, POST and/or PATCH, you must implement the <code>content_types_accepted</code> callback, and one <code>AcceptResource</code> callback for each content-type it returns. Prefix the <code>AcceptResource</code> callback names with <code>from_</code> for clarity. For example <code>from_html</code> or <code>from_json</code>.</p>
-
-<p>Do we want to allow the POST method to create individual resources directly through their URI (like PUT)? Implement the <code>allow_missing_post</code> callback. It is recommended to explicitly use PUT in these cases instead.</p>
-
-<p>May there be conflicts when using PUT to create or replace a resource? Do we want to make sure that two updates around the same time are not cancelling one another? Implement the <code>is_conflict</code> callback.</p>
-
-<h2 id="delete_methods">DELETE methods</h2>
-
-<p>If you implement the method DELETE, you must implement the <code>delete_resource</code> callback.</p>
-
-<p>When <code>delete_resource</code> returns, is the resource completely removed from the server, including from any caching service? If not, and/or if the deletion is asynchronous and we have no way of knowing it has been completed yet, implement the <code>delete_completed</code> callback.</p>

-
-<h1 class="lined-header"><span>Sending a response</span></h1>
-
-<p>The Req object also allows you to send a response.</p>
-
-<p>You can only send one response. Any other attempt will trigger a crash. The response may be sent in one go or with its body streamed by chunks of arbitrary size.</p>
-
-<p>You can also set headers or the response body in advance and Cowboy will use them when you finally do reply.</p>
-
-<h2 id="reply">Reply</h2>
-
-<p>You can send a reply with no particular headers or body. Cowboy will make sure to send the mandatory headers with the response.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{ok, Req2} = cowboy_req:reply(200, Req).
-]]></script>
-
-<p>You can define headers to be sent with the response. Note that header names must be lowercase. Again, Cowboy will make sure to send the mandatory headers with the response.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{ok, Req2} = cowboy_req:reply(303, [
-    {<<"location">>, <<"http://ninenines.eu">>}
-], Req).
-]]></script>
-
-<p>You can override headers that Cowboy would send otherwise. Any header set by the user will be used over the ones set by Cowboy. For example, you can advertise yourself as a different server.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{ok, Req2} = cowboy_req:reply(200, [
-    {<<"server">>, <<"yaws">>}
-], Req).
-]]></script>
-
-<p>We also saw earlier how to force close the connection by overriding the connection header.</p>
-
-<p>Finally, you can also send a body with the response. Cowboy will automatically set the content-length header if you do. We recommend that you set the content-type header so the client may know how to read the body.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{ok, Req2} = cowboy_req:reply(200, [
-    {<<"content-type">>, <<"text/plain">>}
-], "Hello world!", Req).
-]]></script>
-
-<p>Here is the same example but sending HTML this time.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{ok, Req2} = cowboy_req:reply(200, [
-    {<<"content-type">>, <<"text/html">>}
-], "<html><head>Hello world!</head><body><p>Hats off!</p></body></html>", Req).
-]]></script>
-
-<p>Note that the reply is sent immediately.</p>
-
-<h2 id="chunked_reply">Chunked reply</h2>
-
-<p>You can also stream the response body. First, you need to initiate the reply by sending the response status code. Then you can send the body in chunks of arbitrary size.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{ok, Req2} = cowboy_req:chunked_reply(200, Req),
-ok = cowboy_req:chunk("Hello...", Req2),
-ok = cowboy_req:chunk("chunked...", Req2),
-ok = cowboy_req:chunk("world!!", Req2).
-]]></script>
-
-<p>You should make sure to match on <code>ok</code> as an error may be returned.</p>
-
-<p>While it is possible to send a chunked response without a content-type header, it is still recommended. You can set this header or any other just like for normal replies.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{ok, Req2} = cowboy_req:chunked_reply(200, [
-    {<<"content-type">>, <<"text/html">>}
-], Req),
-ok = cowboy_req:chunk("<html><head>Hello world!</head>", Req2),
-ok = cowboy_req:chunk("<body><p>Hats off!</p></body></html>", Req2).
-]]></script>
-
-<p>Note that the reply and each chunk following it are sent immediately.</p>
-
-<h2 id="preset_response_headers">Preset response headers</h2>
-
-<p>You can define response headers in advance. They will be merged into the headers given in the reply call. Headers in the reply call override preset response headers which override the default Cowboy headers.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-Req2 = cowboy_req:set_resp_header(<<"allow">>, "GET", Req).
-]]></script>
-
-<p>You can check if a response header has already been set. This will only check the response headers that you set, and not the ones Cowboy will add when actually sending the reply.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-cowboy_req:has_resp_header(<<"allow">>, Req).
-]]></script>
-
-<p>It will return <code>true</code> if the header is defined, and <code>false</code> otherwise.</p>
-
-<p>Finally, you can also delete a preset response header if needed. If you do, it will not be sent.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-Req2 = cowboy_req:delete_resp_header(<<"allow">>, Req).
-]]></script>
-
-<h2 id="preset_response_body">Preset response body</h2>
-
-<p>You can set the response body in advance. Note that this body will be ignored if you then choose to send a chunked reply, or if you send a reply with an explicit body.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-Req2 = cowboy_req:set_resp_body("Hello world!", Req).
-]]></script>
-
-<p>You can also set a fun that will be called when it is time to send the body. There are three different ways of doing that.</p>
-
-<p>If you know the length of the body that needs to be sent, you should specify it, as it will help clients determine the remaining download time and allow them to inform the user.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-F = fun (Socket, Transport) ->
-    Transport:send(Socket, "Hello world!")
-end,
-Req2 = cowboy_req:set_resp_body_fun(12, F, Req).
-]]></script>
-
-<p>If you do not know the length of the body, you should use a chunked response body fun instead.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-F = fun (SendChunk) ->
-    Body = lists:duplicate(random:uniform(1024, $a)),
-    SendChunk(Body)
-end,
-Req2 = cowboy_req:set_resp_body_fun(chunked, F, Req).
-]]></script>
-
-<p>Finally, you can also send data on the socket directly, without knowing the length in advance. Cowboy may be forced to close the connection at the end of the response though depending on the protocol capabilities.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-F = fun (Socket, Transport) ->
-    Body = lists:duplicate(random:uniform(1024, $a)),
-    Transport:send(Socket, Body)
-end,
-Req2 = cowboy_req:set_resp_body_fun(F, Req).
-]]></script>
-
-<h2 id="sending_files">Sending files</h2>
-
-<p>You can send files directly from disk without having to read them. Cowboy will use the <code>sendfile</code> syscall when possible, which means that the file is sent to the socket directly from the kernel, which is a lot more performant than doing it from userland.</p>
-
-<p>Again, it is recommended to set the size of the file if it can be known in advance.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-F = fun (Socket, Transport) ->
-    Transport:sendfile(Socket, "priv/styles.css")
-end,
-Req2 = cowboy_req:set_resp_body_fun(FileSize, F, Req).
-]]></script>

-<h1 class="lined-header"><span>REST flowcharts</span></h1>
-
-<p>This chapter will explain the REST handler state machine through a number of different diagrams.</p>
-
-<p>There are four main paths that requests may follow. One for the method OPTIONS; one for the methods GET and HEAD; one for the methods PUT, POST and PATCH; and one for the method DELETE.</p>
-
-<p>All paths start with the "Start" diagram, and all paths excluding the OPTIONS path go through the "Content negotiation" diagram and optionally the "Conditional requests" diagram if the resource exists.</p>
-
-<p>The red squares refer to another diagram. The light green squares indicate a response. Other squares may be either a callback or a question answered by Cowboy itself. Green arrows tend to indicate the default behavior if the callback is undefined.</p>
-
-<h2 id="start">Start</h2>
-
-<p>All requests start from here.</p>
-
-<p><img title="REST starting flowchart" src="/docs/en/cowboy/1.0/guide/rest_start.png"/></p>
-
-<p>A series of callbacks are called in succession to perform a general checkup of the service, the request line and request headers.</p>
-
-<p>The request body, if any, is not expected to have been received for any of these steps. It is only processed at the end of the "PUT, POST and PATCH methods" diagram, when all conditions have been met.</p>
-
-<p>The <code>known_methods</code> and <code>allowed_methods</code> callbacks return a list of methods. Cowboy then checks if the request method is in the list, and stops otherwise.</p>
-
-<p>The <code>is_authorized</code> callback may be used to check that access to the resource is authorized. Authentication may also be performed as needed. When authorization is denied, the return value from the callback must include a challenge applicable to the requested resource, which will be sent back to the client in the www-authenticate header.</p>
-
-<p>This diagram is immediately followed by either the "OPTIONS method" diagram when the request method is OPTIONS, or the "Content negotiation" diagram otherwise.</p>
-
-<h2 id="options_method">OPTIONS method</h2>
-
-<p>This diagram only applies to OPTIONS requests.</p>
-
-<p><img title="REST OPTIONS method flowchart" src="/docs/en/cowboy/1.0/guide/rest_options.png"/></p>
-
-<p>The <code>options</code> callback may be used to add information about the resource, such as media types or languages provided; allowed methods; any extra information. A response body may also be set, although clients should not be expected to read it.</p>
-
-<p>If the <code>options</code> callback is not defined, Cowboy will send a response containing the list of allowed methods by default.</p>
-
-<h2 id="content_negotiation">Content negotiation</h2>
-
-<p>This diagram applies to all request methods other than OPTIONS. It is executed right after the "Start" diagram is completed.</p>
-
-<p><img title="REST content negotiation flowchart" src="/docs/en/cowboy/1.0/guide/rest_conneg.png"/></p>
-
-<p>The purpose of these steps is to determine an appropriate representation to be sent back to the client.</p>
-
-<p>The request may contain any of the accept header; the accept-language header; or the accept-charset header. When present, Cowboy will parse the headers and then call the corresponding callback to obtain the list of provided content-type, language or charset for this resource. It then automatically select the best match based on the request.</p>
-
-<p>If a callback is not defined, Cowboy will select the content-type, language or charset that the client prefers.</p>
-
-<p>The <code>content_types_provided</code> also returns the name of a callback for every content-type it accepts. This callback will only be called at the end of the "GET and HEAD methods" diagram, when all conditions have been met.</p>
-
-<p>The selected content-type, language and charset are saved as meta values in the Req object. You <em>should</em> use the appropriate representation if you set a response body manually (alongside an error code, for example).</p>
-
-<p>This diagram is immediately followed by the "GET and HEAD methods" diagram, the "PUT, POST and PATCH methods" diagram, or the "DELETE method" diagram, depending on the method.</p>
-
-<h2 id="get_and_head_methods">GET and HEAD methods</h2>
-
-<p>This diagram only applies to GET and HEAD requests.</p>
-
-<p>For a description of the <code>cond</code> step, please see the "Conditional requests" diagram.</p>
-
-<p><img title="REST GET/HEAD methods flowchart" src="/docs/en/cowboy/1.0/guide/rest_get_head.png"/></p>
-
-<p>When the resource exists, and the conditional steps succeed, the resource can be retrieved.</p>
-
-<p>Cowboy prepares the response by first retrieving metadata about the representation, then by calling the <code>ProvideResource</code> callback. This is the callback you defined for each content-types you returned from <code>content_types_provided</code>. This callback returns the body that will be sent back to the client, or a fun if the body must be streamed.</p>
-
-<p>When the resource does not exist, Cowboy will figure out whether the resource existed previously, and if so whether it was moved elsewhere in order to redirect the client to the new URI.</p>
-
-<p>The <code>moved_permanently</code> and <code>moved_temporarily</code> callbacks must return the new location of the resource if it was in fact moved.</p>
-
-<h2 id="put,_post_and_patch_methods">PUT, POST and PATCH methods</h2>
-
-<p>This diagram only applies to PUT, POST and PATCH requests.</p>
-
-<p>For a description of the <code>cond</code> step, please see the "Conditional requests" diagram.</p>
-
-<p><img title="REST PUT/POST/PATCH methods flowchart" src="/docs/en/cowboy/1.0/guide/rest_put_post_patch.png"/></p>
-
-<p>When the resource exists, first the conditional steps are executed. When that succeeds, and the method is PUT, Cowboy will call the <code>is_conflict</code> callback. This function can be used to prevent potential race conditions, by locking the resource for example.</p>
-
-<p>Then all three methods reach the <code>content_types_accepted</code> step that we will describe in a few paragraphs.</p>
-
-<p>When the resource does not exist, and the method is PUT, Cowboy will check for conflicts and then move on to the <code>content_types_accepted</code> step. For other methods, Cowboy will figure out whether the resource existed previously, and if so whether it was moved elsewhere. If the resource is truly non-existent, the method is POST and the call for <code>allow_missing_post</code> returns <code>true</code>, then Cowboy will move on to the <code>content_types_accepted</code> step. Otherwise the request processing ends there.</p>
-
-<p>The <code>moved_permanently</code> and <code>moved_temporarily</code> callbacks must return the new location of the resource if it was in fact moved.</p>
-
-<p>The <code>content_types_accepted</code> returns a list of content-types it accepts, but also the name of a callback for each of them. Cowboy will select the appropriate callback for processing the request body and call it.</p>
-
-<p>This callback may return one of three different return values.</p>
-
-<p>If an error occurred while processing the request body, it must return <code>false</code> and Cowboy will send an appropriate error response.</p>
-
-<p>If the method is POST, then you may return <code>true</code> with an URI of where the resource has been created. This is especially useful for writing handlers for collections.</p>
-
-<p>Otherwise, return <code>true</code> to indicate success. Cowboy will select the appropriate response to be sent depending on whether a resource has been created, rather than modified, and on the availability of a location header or a body in the response.</p>
-
-<h2 id="delete_method">DELETE method</h2>
-
-<p>This diagram only applies to DELETE requests.</p>
-
-<p>For a description of the <code>cond</code> step, please see the "Conditional requests" diagram.</p>
-
-<p><img title="REST DELETE method flowchart" src="/docs/en/cowboy/1.0/guide/rest_delete.png"/></p>
-
-<p>When the resource exists, and the conditional steps succeed, the resource can be deleted.</p>
-
-<p>Deleting the resource is a two steps process. First the callback <code>delete_resource</code> is executed. Use this callback to delete the resource.</p>
-
-<p>Because the resource may be cached, you must also delete all cached representations of this resource in the system. This operation may take a while though, so you may return before it finished.</p>
-
-<p>Cowboy will then call the <code>delete_completed</code> callback. If you know that the resource has been completely deleted from your system, including from caches, then you can return <code>true</code>. If any doubts persist, return <code>false</code>. Cowboy will assume <code>true</code> by default.</p>
-
-<p>To finish, Cowboy checks if you set a response body, and depending on that, sends the appropriate response.</p>
-
-<p>When the resource does not exist, Cowboy will figure out whether the resource existed previously, and if so whether it was moved elsewhere in order to redirect the client to the new URI.</p>
-
-<p>The <code>moved_permanently</code> and <code>moved_temporarily</code> callbacks must return the new location of the resource if it was in fact moved.</p>
-
-<h2 id="conditional_requests">Conditional requests</h2>
-
-<p>This diagram applies to all request methods other than OPTIONS. It is executed right after the <code>resource_exists</code> callback, when the resource exists.</p>
-
-<p><img title="REST conditional requests flowchart" src="/docs/en/cowboy/1.0/guide/rest_cond.png"/></p>
-
-<p>A request becomes conditional when it includes either of the if-match header; the if-unmodified-since header; the if-none-match header; or the if-modified-since header.</p>
-
-<p>If the condition fails, the request ends immediately without any retrieval or modification of the resource.</p>
-
-<p>The <code>generate_etag</code> and <code>last_modified</code> are called as needed. Cowboy will only call them once and then cache the results for subsequent use.</p>

-<h1 class="lined-header"><span>REST handlers</span></h1>
-
-<p>REST is implemented in Cowboy as a protocol upgrade. Once upgraded, the request is handled as a state machine with many optional callbacks describing the resource and modifying the machine's behavior.</p>
-
-<p>The REST handler is the recommended way to handle requests.</p>
-
-<h2 id="initialization">Initialization</h2>
-
-<p>First, the <code>init/3</code> callback is called. This callback is common to all handlers. To use REST for the current request, this function must return an <code>upgrade</code> tuple.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-init({tcp, http}, Req, Opts) ->
-    {upgrade, protocol, cowboy_rest}.
-]]></script>
-
-<p>Cowboy will then switch to the REST protocol and start executing the state machine, starting from <code>rest_init/2</code> if it's defined, and ending with <code>rest_terminate/2</code> also if defined.</p>
-
-<h2 id="methods">Methods</h2>
-
-<p>The REST component has code for handling the following HTTP methods: HEAD, GET, POST, PATCH, PUT, DELETE and OPTIONS.</p>
-
-<p>Other methods can be accepted, however they have no specific callback defined for them at this time.</p>
-
-<h2 id="callbacks">Callbacks</h2>
-
-<p>All callbacks are optional. Some may become mandatory depending on what other defined callbacks return. The various flowcharts in the next chapter should be a useful to determine which callbacks you need.</p>
-
-<p>When the request starts being processed, Cowboy will call the <code>rest_init/2</code> function if it is defined, with the Req object and the handler options as arguments. This function must return <code>{ok, Req, State}</code> where <code>State</code> is the handler's state that all subsequent callbacks will receive.</p>
-
-<p>At the end of every request, the special callback <code>rest_terminate/2</code> will be called if it is defined. It cannot be used to send a reply, and must always return <code>ok</code>.</p>
-
-<p>All other callbacks are resource callbacks. They all take two arguments, the Req object and the State, and return a three-element tuple of the form <code>{Value, Req, State}</code>.</p>
-
-<p>The following table summarizes the callbacks and their default values. If the callback isn't defined, then the default value will be used. Please look at the flowcharts to find out the result of each return value.</p>
-
-<p>All callbacks can also return <code>{halt, Req, State}</code> to stop execution of the request, at which point <code>rest_terminate/2</code> will be called.</p>
-
-<p>In the following table, "skip" means the callback is entirely skipped if it is undefined, moving directly to the next step. Similarly, "none" means there is no default value for this callback.</p>
-
-<table class="table-bordered table-condensed table-striped">
-<thead>
-<tr><th>Callback name</th><th>Default value</th></tr>
-</thead>
-<tbody>
-<tr><td>allowed_methods</td><td><code>[<<"GET">>, <<"HEAD">>, <<"OPTIONS">>]</code></td></tr>
-<tr><td>allow_missing_post</td><td><code>true</code></td></tr>

-<tr><td>valid_entity_length</td><td><code>true</code></td></tr>
-<tr><td>variances</td><td><code>[]</code></td></tr>
-</tbody>
-</table>
-
-<p>As you can see, Cowboy tries to move on with the request whenever possible by using well thought out default values.</p>
-
-<p>In addition to these, there can be any number of user-defined callbacks that are specified through <code>content_types_accepted/2</code> and <code>content_types_provided/2</code>. They can take any name, however it is recommended to use a separate prefix for the callbacks of each function. For example, <code>from_html</code> and <code>to_html</code> indicate in the first case that we're accepting a resource given as HTML, and in the second case that we send one as HTML.</p>
-
-<h2 id="meta_data">Meta data</h2>
-
-<p>Cowboy will set informative meta values at various points of the execution. You can retrieve them using <code>cowboy_req:meta/{2,3}</code>. The values are defined in the following table.</p>
-
-<table class="table-bordered table-condensed table-striped">
-<thead>
-<tr><th>Meta key</th><th>Details</th></tr>
-</thead>
-<tbody>
-<tr><td>media_type</td><td>The content-type negotiated for the response entity.</td></tr>
-<tr><td>language</td><td>The language negotiated for the response entity.</td></tr>
-<tr><td>charset</td><td>The charset negotiated for the response entity.</td></tr>
-</tbody>
-</table>
-
-<p>They can be used to send a proper body with the response to a request that used a method other than HEAD or GET.</p>
-
-<h2 id="response_headers">Response headers</h2>
-
-<p>Cowboy will set response headers automatically over the execution of the REST code. They are listed in the following table.</p>
-
-<table class="table-bordered table-condensed table-striped">
-<thead>
-<tr><th>Header name</th><th>Details</th></tr>
-</thead>
-<tbody>
-<tr><td>content-language</td><td>Language used in the response body</td></tr>
-<tr><td>content-type</td><td>Media type and charset of the response body</td></tr>
-<tr><td>etag</td><td>Etag of the resource</td></tr>
-<tr><td>expires</td><td>Expiration date of the resource</td></tr>
-<tr><td>last-modified</td><td>Last modification date for the resource</td></tr>
-<tr><td>location</td><td>Relative or absolute URI to the requested resource</td></tr>
-<tr><td>vary</td><td>List of headers that may change the representation of the resource</td></tr>

-<h1 class="lined-header"><span>REST principles</span></h1>
-
-<p>This chapter will attempt to define the concepts behind REST and explain what makes a service RESTful.</p>
-
-<p>REST is often confused with performing a distinct operation depending on the HTTP method, while using more than the GET and POST methods. That's highly misguided at best.</p>
-
-<p>We will first attempt to define REST and will look at what it means in the context of HTTP and the Web. For a more in-depth explanation of REST, you can read <a href="http://www.ics.uci.edu/~fielding/pubs/dissertation/top.htm">Roy T. Fielding's dissertation</a> as it does a great job explaining where it comes from and what it achieves.</p>
-
-<h2 id="rest_architecture">REST architecture</h2>
-
-<p>REST is a <em>client-server</em> architecture. The client and the server both have a different set of concerns. The server stores and/or manipulates information and makes it available to the user in an efficient manner. The client takes that information and displays it to the user and/or uses it to perform subsequent requests for information. This separation of concerns allows both the client and the server to evolve independently as it only requires that the interface stays the same.</p>
-
-<p>REST is <em>stateless</em>. That means the communication between the client and the server always contains all the information needed to perform the request. There is no session state in the server, it is kept entirely on the client's side. If access to a resource requires authentication, then the client needs to authenticate itself with every request.</p>
-
-<p>REST is <em>cacheable</em>. The client, the server and any intermediary components can all cache resources in order to improve performance.</p>
-
-<p>REST provides a <em>uniform interface</em> between components. This simplifies the architecture, as all components follow the same rules to speak to one another. It also makes it easier to understand the interactions between the different components of the system. A number of constraints are required to achieve this. They are covered in the rest of the chapter.</p>
-
-<p>REST is a <em>layered system</em>. Individual components cannot see beyond the immediate layer with which they are interacting. This means that a client connecting to an intermediate component, like a proxy, has no knowledge of what lies beyond. This allows components to be independent and thus easily replaceable or extendable.</p>
-
-<p>REST optionally provides <em>code on demand</em>. Code may be downloaded to extend client functionality. This is optional however because the client may not be able to download or run this code, and so a REST component cannot rely on it being executed.</p>
-
-<h2 id="resources_and_resource_identifiers">Resources and resource identifiers</h2>
-
-<p>A resource is an abstract concept. In a REST system, any information that can be named may be a resource. This includes documents, images, a collection of resources and any other information. Any information that can be the target of an hypertext link can be a resource.</p>
-
-<p>A resource is a conceptual mapping to a set of entities. The set of entities evolves over time; a resource doesn't. For example a resource can map to "users who have logged in this past month" and another to "all users". At some point in time they may map to the same set of entities, because all users logged in this past month. But they are still different resources. Similarly, if nobody logged in recently, then the first resource may map to the empty set. This resource exists regardless of the information it maps to.</p>
-
-<p>Resources are identified by uniform resource identifiers, also known as URIs. Sometimes internationalized resource identifiers, or IRIs, may also be used, but these can be directly translated into a URI.</p>
-
-<p>In practice we will identify two kinds of resources. Individual resources map to a set of one element, for example "user Joe". Collection of resources map to a set of 0 to N elements, for example "all users".</p>
-
-<h2 id="resource_representations">Resource representations</h2>
-
-<p>The representation of a resource is a sequence of bytes associated with metadata.</p>
-
-<p>The metadata comes as a list of key-value pairs, where the name corresponds to a standard that defines the value's structure and semantics. With HTTP, the metadata comes in the form of request or response headers. The headers' structure and semantics are well defined in the HTTP standard. Metadata includes representation metadata, resource metadata and control data.</p>
-
-<p>The representation metadata gives information about the representation, such as its media type, the date of last modification, or even a checksum.</p>
-
-<p>Resource metadata could be link to related resources or information about additional representations of the resource.</p>
-
-<p>Control data allows parameterizing the request or response. For example, we may only want the representation returned if it is more recent than the one we have in cache. Similarly, we may want to instruct the client about how it should cache the representation. This isn't restricted to caching. We may for example want to store a new representation of a resource only if it wasn't modified since we first retrieved it.</p>
-
-<p>The data format of a representation is also known as the media type. Some media types are intended for direct rendering to the user, while others are intended for automated processing. The media type is a key component of the REST architecture.</p>
-
-<h2 id="self-descriptive_messages">Self-descriptive messages</h2>
-
-<p>Messages must be self-descriptive. That means that the data format of a representation must always come with its media type (and similarly requesting a resource involves choosing the media type of the representation returned). If you are sending HTML, then you must say it is HTML by sending the media type with the representation. In HTTP this is done using the content-type header.</p>
-
-<p>The media type is often an IANA registered media type, like <code>text/html</code> or <code>image/png</code>, but does not need to be. Exactly two things are important for respecting this constraint: that the media type is well specified, and that the sender and recipient agree about what the media type refers to.</p>
-
-<p>This means that you can create your own media types, like <code>application/x-mine</code>, and that as long as you write the specifications for it and that both endpoints agree about it then the constraint is respected.</p>
-
-<h2 id="hypermedia_as_the_engine_of_application_state">Hypermedia as the engine of application state</h2>
-
-<p>The last constraint is generally where services that claim to be RESTful fail. Interactions with a server must be entirely driven by hypermedia. The client does not need any prior knowledge of the service in order to use it, other than an entry point and of course basic understanding of the media type of the representations, at the very least enough to find and identify hyperlinks and link relations.</p>
-
-<p>To give a simple example, if your service only works with the <code>application/json</code> media type then this constraint cannot be respected (as there are no concept of links in JSON) and thus your service isn't RESTful. This is the case for the majority of self-proclaimed REST services.</p>
-
-<p>On the other hand if you create a JSON based media type that has a concept of links and link relations, then your service might be RESTful.</p>
-
-<p>Respecting this constraint means that the entirety of the service becomes self-discoverable, not only the resources in it, but also the operations you can perform on it. This makes clients very thin as there is no need to implement anything specific to the service to operate on it.</p>

-<h1 class="lined-header"><span>Routing</span></h1>
-
-<p>Cowboy does nothing by default.</p>
-
-<p>To make Cowboy useful, you need to map URLs to Erlang modules that will handle the requests. This is called routing.</p>
-
-<p>When Cowboy receives a request, it tries to match the requested host and path to the resources given in the dispatch rules. If it matches, then the associated Erlang code will be executed.</p>
-
-<p>Routing rules are given per host. Cowboy will first match on the host, and then try to find a matching path.</p>
-
-<p>Routes need to be compiled before they can be used by Cowboy.</p>
-
-<h2 id="structure">Structure</h2>
-
-<p>The general structure for the routes is defined as follow.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-Routes = [Host1, Host2, ... HostN].
-]]></script>
-
-<p>Each host contains matching rules for the host along with optional constraints, and a list of routes for the path component.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-Host1 = {HostMatch, PathsList}.
-Host2 = {HostMatch, Constraints, PathsList}.
-]]></script>
-
-<p>The list of routes for the path component is defined similar to the list of hosts.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-PathsList = [Path1, Path2, ... PathN].
-]]></script>
-
-<p>Finally, each path contains matching rules for the path along with optional constraints, and gives us the handler module to be used along with options that will be given to it on initialization.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-Path1 = {PathMatch, Handler, Opts}.
-Path2 = {PathMatch, Constraints, Handler, Opts}.
-]]></script>
-
-<p>Continue reading to learn more about the match syntax and the optional constraints.</p>
-
-<h2 id="match_syntax">Match syntax</h2>
-
-<p>The match syntax is used to associate host names and paths with their respective handlers.</p>
-
-<p>The match syntax is the same for host and path with a few subtleties. Indeed, the segments separator is different, and the host is matched starting from the last segment going to the first. All examples will feature both host and path match rules and explain the differences when encountered.</p>
-
-<p>Excluding special values that we will explain at the end of this section, the simplest match value is a host or a path. It can be given as either a <code>string()</code> or a <code>binary()</code>.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-PathMatch1 = "/".
-PathMatch2 = "/path/to/resource".
-
-HostMatch1 = "cowboy.example.org".
-]]></script>
-
-<p>As you can see, all paths defined this way must start with a slash character. Note that these two paths are identical as far as routing is concerned.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-PathMatch2 = "/path/to/resource".
-PathMatch3 = "/path/to/resource/".
-]]></script>
-
-<p>Hosts with and without a trailing dot are equivalent for routing. Similarly, hosts with and without a leading dot are also equivalent.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-HostMatch1 = "cowboy.example.org".
-HostMatch2 = "cowboy.example.org.".
-HostMatch3 = ".cowboy.example.org".
-]]></script>
-
-<p>It is possible to extract segments of the host and path and to store the values in the <code>Req</code> object for later use. We call these kind of values bindings.</p>
-
-<p>The syntax for bindings is very simple. A segment that begins with the <code>:</code> character means that what follows until the end of the segment is the name of the binding in which the segment value will be stored.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-PathMatch = "/hats/:name/prices".
-HostMatch = ":subdomain.example.org".
-]]></script>
-
-<p>If these two end up matching when routing, you will end up with two bindings defined, <code>subdomain</code> and <code>name</code>, each containing the segment value where they were defined. For example, the URL <code>http://test.example.org/hats/wild_cowboy_legendary/prices</code> will result in having the value <code>test</code> bound to the name <code>subdomain</code> and the value <code>wild_cowboy_legendary</code> bound to the name <code>name</code>. They can later be retrieved using <code>cowboy_req:binding/{2,3}</code>. The binding name must be given as an atom.</p>
-
-<p>There is a special binding name you can use to mimic the underscore variable in Erlang. Any match against the <code>_</code> binding will succeed but the data will be discarded. This is especially useful for matching against many domain names in one go.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-HostMatch = "ninenines.:_".
-]]></script>
-
-<p>Similarly, it is possible to have optional segments. Anything between brackets is optional.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-PathMatch = "/hats/[page/:number]".
-HostMatch = "[www.]ninenines.eu".
-]]></script>
-
-<p>You can also have imbricated optional segments.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-PathMatch = "/hats/[page/[:number]]".
-]]></script>
-
-<p>You can retrieve the rest of the host or path using <code>[...]</code>. In the case of hosts it will match anything before, in the case of paths anything after the previously matched segments. It is a special case of optional segments, in that it can have zero, one or many segments. You can then find the segments using <code>cowboy_req:host_info/1</code> and <code>cowboy_req:path_info/1</code> respectively. They will be represented as a list of segments.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-PathMatch = "/hats/[...]".
-HostMatch = "[...]ninenines.eu".
-]]></script>
-
-<p>If a binding appears twice in the routing rules, then the match will succeed only if they share the same value. This copies the Erlang pattern matching behavior.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-PathMatch = "/hats/:name/:name".
-]]></script>
-
-<p>This is also true when an optional segment is present. In this case the two values must be identical only if the segment is available.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-PathMatch = "/hats/:name/[:name]".
-]]></script>
-
-<p>If a binding is defined in both the host and path, then they must also share the same value.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-PathMatch = "/:user/[...]".
-HostMatch = ":user.github.com".
-]]></script>
-
-<p>Finally, there are two special match values that can be used. The first is the atom <code>'_'</code> which will match any host or path.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-PathMatch = '_'.
-HostMatch = '_'.
-]]></script>
-
-<p>The second is the special host match <code>"*"</code> which will match the wildcard path, generally used alongside the <code>OPTIONS</code> method.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-HostMatch = "*".
-]]></script>
-
-<h2 id="constraints">Constraints</h2>
-
-<p>After the matching has completed, the resulting bindings can be tested against a set of constraints. Constraints are only tested when the binding is defined. They run in the order you defined them. The match will succeed only if they all succeed.</p>
-
-<p>They are always given as a two or three elements tuple, where the first element is the name of the binding, the second element is the constraint's name, and the optional third element is the constraint's arguments.</p>
-
-<p>The following constraints are currently defined:</p>
-
-<ul>
-<li>{Name, int}</li>
-<li>{Name, function, fun ((Value) -> true | {true, NewValue} | false)}</li>
-</ul>
-
-<p>The <code>int</code> constraint will check if the binding is a binary string representing an integer, and if it is, will convert the value to integer.</p>
-
-<p>The <code>function</code> constraint will pass the binding value to a user specified function that receives the binary value as its only argument and must return whether it fulfills the constraint, optionally modifying the value. The value thus returned can be of any type.</p>
-
-<p>Note that constraint functions SHOULD be pure and MUST NOT crash.</p>
-
-<h2 id="compilation">Compilation</h2>
-
-<p>The structure defined in this chapter needs to be compiled before it is passed to Cowboy. This allows Cowboy to efficiently lookup the correct handler to run instead of having to parse the routes repeatedly.</p>
-
-<p>This can be done with a simple call to <code>cowboy_router:compile/1</code>.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-Dispatch = cowboy_router:compile([
-    %% {HostMatch, list({PathMatch, Handler, Opts})}
-    {'_', [{'_', my_handler, []}]}
-]),
-%% Name, NbAcceptors, TransOpts, ProtoOpts
-cowboy:start_http(my_http_listener, 100,
-    [{port, 8080}],
-    [{env, [{dispatch, Dispatch}]}]
-).
-]]></script>
-
-<p>Note that this function will return <code>{error, badarg}</code> if the structure given is incorrect.</p>
-
-<h2 id="live_update">Live update</h2>
-
-<p>You can use the <code>cowboy:set_env/3</code> function for updating the dispatch list used by routing. This will apply to all new connections accepted by the listener.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-cowboy:set_env(my_http_listener, dispatch,
-    cowboy_router:compile(Dispatch)).
-]]></script>
-
-<p>Note that you need to compile the routes before updating.</p>

-<h1 class="lined-header"><span>Static handler</span></h1>
-
-<p>The static handler is a built-in REST handler for serving files. It is available as a convenience and provides a quick solution for serving files during development.</p>
-
-<p>For systems in production, consider using one of the many Content Distribution Network (CDN) available on the market, as they are the best solution for serving files. They are covered in the next chapter. If you decide against using a CDN solution, then please look at the chapter after that, as it explains how to efficiently serve static files on your own.</p>
-
-<p>The static handler can serve either one file or all files from a given directory. It can also send etag headers for client-side caching.</p>
-
-<p>To use the static file handler, simply add routes for it with the appropriate options.</p>
-
-<h2 id="serve_one_file">Serve one file</h2>
-
-<p>You can use the static handler to serve one specific file from an application's private directory. This is particularly useful to serve an <code>index.html</code> file when the client requests the <code>/</code> path, for example. The path configured is relative to the given application's private directory.</p>
-
-<p>The following rule will serve the file <code>static/index.html</code> from the application <code>my_app</code>'s priv directory whenever the path <code>/</code> is accessed.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{"/", cowboy_static, {priv_file, my_app, "static/index.html"}}
-]]></script>
-
-<p>You can also specify the absolute path to a file, or the path to the file relative to the current directory.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{"/", cowboy_static, {file, "/var/www/index.html"}}
-]]></script>
-
-<h2 id="serve_all_files_from_a_directory">Serve all files from a directory</h2>
-
-<p>You can also use the static handler to serve all files that can be found in the configured directory. The handler will use the <code>path_info</code> information to resolve the file location, which means that your route must end with a <code>[...]</code> pattern for it to work. All files are served, including the ones that may be found in subfolders.</p>
-
-<p>You can specify the directory relative to an application's private directory.</p>
-
-<p>The following rule will serve any file found in the application <code>my_app</code>'s priv directory inside the <code>static/assets</code> folder whenever the requested path begins with <code>/assets/</code>.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{"/assets/[...]", cowboy_static, {priv_dir, my_app, "static/assets"}}
-]]></script>
-
-<p>You can also specify the absolute path to the directory or set it relative to the current directory.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{"/assets/[...]", cowboy_static, {dir, "/var/www/assets"}}
-]]></script>
-
-<h2 id="customize_the_mimetype_detection">Customize the mimetype detection</h2>
-
-<p>By default, Cowboy will attempt to recognize the mimetype of your static files by looking at the extension.</p>
-
-<p>You can override the function that figures out the mimetype of the static files. It can be useful when Cowboy is missing a mimetype you need to handle, or when you want to reduce the list to make lookups faster. You can also give a hard-coded mimetype that will be used unconditionally.</p>
-
-<p>Cowboy comes with two functions built-in. The default function only handles common file types used when building Web applications. The other function is an extensive list of hundreds of mimetypes that should cover almost any need you may have. You can of course create your own function.</p>
-
-<p>To use the default function, you should not have to configure anything, as it is the default. If you insist, though, the following will do the job.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{"/assets/[...]", cowboy_static, {priv_dir, my_app, "static/assets",
-    [{mimetypes, cow_mimetypes, web}]}}
-]]></script>
-
-<p>As you can see, there is an optional field that may contain a list of less used options, like mimetypes or etag. All option types have this optional field.</p>
-
-<p>To use the function that will detect almost any mimetype, the following configuration will do.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{"/assets/[...]", cowboy_static, {priv_dir, my_app, "static/assets",
-    [{mimetypes, cow_mimetypes, all}]}}
-]]></script>
-
-<p>You probably noticed the pattern by now. The configuration expects a module and a function name, so you can use any of your own functions instead.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{"/assets/[...]", cowboy_static, {priv_dir, my_app, "static/assets",
-    [{mimetypes, Module, Function}]}}
-]]></script>
-
-<p>The function that performs the mimetype detection receives a single argument that is the path to the file on disk. It is recommended to return the mimetype in tuple form, although a binary string is also allowed (but will require extra processing). If the function can't figure out the mimetype, then it should return <code>{<<"application">>, <<"octet-stream">>, []}</code>.</p>
-
-<p>When the static handler fails to find the extension in the list, it will send the file as <code>application/octet-stream</code>. A browser receiving such file will attempt to download it directly to disk.</p>
-
-<p>Finally, the mimetype can be hard-coded for all files. This is especially useful in combination with the <code>file</code> and <code>priv_file</code> options as it avoids needless computation.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{"/", cowboy_static, {priv_file, my_app, "static/index.html",
-    [{mimetypes, {<<"text">>, <<"html">>, []}}]}}
-]]></script>
-
-<h2 id="generate_an_etag">Generate an etag</h2>
-
-<p>By default, the static handler will generate an etag header value based on the size and modified time. This solution can not be applied to all systems though. It would perform rather poorly over a cluster of nodes, for example, as the file metadata will vary from server to server, giving a different etag on each server.</p>
-
-<p>You can however change the way the etag is calculated.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{"/assets/[...]", cowboy_static, {priv_dir, my_app, "static/assets",
-    [{etag, Module, Function}]}}
-]]></script>
-
-<p>This function will receive three arguments: the path to the file on disk, the size of the file and the last modification time. In a distributed setup, you would typically use the file path to retrieve an etag value that is identical across all your servers.</p>
-
-<p>You can also completely disable etag handling.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-{"/assets/[...]", cowboy_static, {priv_dir, my_app, "static/assets",
-    [{etag, false}]}}
-]]></script>

-<h1 class="lined-header"><span>Protocol upgrades</span></h1>
-
-<p>Cowboy features many different handlers, each for different purposes. All handlers have a common entry point: the <code>init/3</code> function.</p>
-
-<p>The default handler type is the simple HTTP handler.</p>
-
-<p>To switch to a different protocol, you must perform a protocol upgrade. This is what is done for Websocket and REST and is explained in details in the respective chapters.</p>
-
-<p>You can also create your own protocol on top of Cowboy and use the protocol upgrade mechanism to switch to it.</p>
-
-<p>For example, if you create the <code>my_protocol</code> module implementing the <code>cowboy_sub_protocol</code> behavior, then you can upgrade to it by simply returning the module name from <code>init/3</code>.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-init(_, _, _Opts) ->
-    {upgrade, protocol, my_protocol}.
-]]></script>
-
-<p>The <code>cowboy_sub_protocol</code> behavior only requires one callback, <code>upgrade/4</code>. It receives the Req object, the middleware environment, and the handler and options for this request. This is the same module as the <code>init/3</code> function and the same options that were passed to it.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-upgrade(Req, Env, Handler, HandlerOpts) ->
-    %% ...
-]]></script>
-
-<p>This callback is expected to behave like a middleware. Please see the corresponding chapter for more information.</p>

-
-<h1 class="lined-header"><span>Handling Websocket connections</span></h1>
-
-<p>A special handler is required for handling Websocket connections. Websocket handlers allow you to initialize the connection, handle incoming frames from the socket, handle incoming Erlang messages and then clean up on termination.</p>
-
-<p>Websocket handlers essentially act as a bridge between the client and the Erlang system. They will typically do little more than socket communication and decoding/encoding of frames.</p>
-
-<h2 id="initialization">Initialization</h2>
-
-<p>First, the <code>init/3</code> callback is called. This callback is common to all handlers. To establish a Websocket connection, this function must return an <code>upgrade</code> tuple.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-init(_, Req, Opts) ->
-	{upgrade, protocol, cowboy_websocket}.
-]]></script>
-
-<p>It is also possible to return an update Req object and options using the longer form of this tuple.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-init(_Type, Req, Opts) ->
-	{upgrade, protocol, cowboy_websocket, Req, Opts}.
-]]></script>
-
-<p>Upon receiving this tuple, Cowboy will switch to the code that handles Websocket connections. It does not immediately perform the handshake however. First, it calls the <code>websocket_init/3</code> callback.</p>
-
-<p>This function must be used to initialize the state, and can also be used to register the process, start a timer, etc. As long as the function returns an <code>ok</code> tuple, then Cowboy performs the Websocket handshake.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-websocket_init(_Type, Req, _Opts) ->
-    {ok, Req, #state{}}.
-]]></script>
-
-<p>A <code>shutdown</code> tuple can be returned to refuse to perform the handshake. When doing so, Cowboy will send a <code>400 Bad Request</code> response to the client and close the connection.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-websocket_init(_Type, Req, _Opts) ->
-	{shutdown, Req}.
-]]></script>
-
-<p>It is also possible to perform a <code>cowboy_req:reply/{2,3,4}</code> before returning a <code>shutdown</code> tuple, allowing you to override the response sent back to the client.</p>
-
-<p>Note that browser support for handling Websocket connection failures may vary.</p>
-
-<p>If the sec-websocket-protocol header was sent with the request for establishing a Websocket connection, then the Websocket handler <em>must</em> select one of these subprotocol and send it back to the client, otherwise the client might decide to close the connection, assuming no correct subprotocol was found.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-websocket_init(_Type, Req, _Opts) ->
-	case cowboy_req:parse_header(<<"sec-websocket-protocol">>, Req) of
-		{ok, undefined, Req2} ->
-			{ok, Req, #state{}};
-		{ok, Subprotocols, Req2} ->
-			case lists:keymember(<<"mychat2">>, 1, Subprotocols) of
-				true ->
-					Req3 = cowboy_req:set_resp_header(<<"sec-websocket-protocol">>,
-						<<"mychat2">>, Req2),
-					{ok, Req3, #state{}};
-				false ->
-					{shutdown, Req2}
-			end
-	end.
-]]></script>
-
-<p>It is not recommended to wait too long inside the <code>websocket_init/3</code> function. Any extra initialization may be done after returning by sending yourself a message before doing anything. Any message sent to <code>self()</code> from <code>websocket_init/3</code> is guaranteed to arrive before any frames from the client.</p>
-
-<p>It is also very easy to ensure that this message arrives before any message from other processes by sending it before registering or enabling timers.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-websocket_init(_Type, Req, _Opts) ->
-	self() ! post_init,
-	%% Register process here...
-	{ok, Req, #state{}}.
-
-websocket_info(post_init, Req, State) ->
-	%% Perform post_init initialization here...
-	{ok, Req, State}.
-]]></script>
-
-<h2 id="handling_frames_from_the_client">Handling frames from the client</h2>
-
-<p>Cowboy will call <code>websocket_handle/3</code> whenever a text, binary, ping or pong frame arrives from the client. Note that in the case of ping and pong frames, no action is expected as Cowboy automatically replies to ping frames.</p>
-
-<p>The handler can decide to send frames to the socket, shutdown or just continue without sending anything.</p>
-
-<p>The following snippet echoes back any text frame received and ignores all others.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-websocket_handle(Frame = {text, _}, Req, State) ->
-	{reply, Frame, Req, State};
-websocket_handle(_Frame, Req, State) ->
-	{ok, Req, State}.
-]]></script>
-
-<h2 id="handling_erlang_messages">Handling Erlang messages</h2>
-
-<p>Cowboy will call <code>websocket_info/3</code> whenever an Erlang message arrives.</p>
-
-<p>The handler can decide to send frames to the socket, shutdown or just continue without sending anything.</p>
-
-<p>The following snippet forwards any <code>log</code> message to the socket and ignores all others.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-websocket_info({log, Text}, Req, State) ->
-	{reply, {text, Text}, Req, State};
-websocket_info(_Info, Req, State) ->
-	{ok, Req, State}.
-]]></script>
-
-<h2 id="sending_frames_to_the_socket">Sending frames to the socket</h2>
-
-<p>Cowboy allows sending either a single frame or a list of frames to the socket. Any frame can be sent: text, binary, ping, pong or close frames.</p>
-
-<p>The following example sends three frames using a single <code>reply</code> tuple.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-websocket_info(hello_world, Req, State) ->
-	{reply, [
-		{text, "Hello"},
-		{text, <<"world!">>},
-		{binary, <<0:8000>>}
-	], Req, State};
-%% More websocket_info/3 clauses here...
-]]></script>
-
-<p>Note that the payload for text and binary frames is of type <code>iodata()</code>, meaning it can be either a <code>binary()</code> or an <code>iolist()</code>.</p>
-
-<p>Sending a <code>close</code> frame will immediately initiate the closing of the Websocket connection. Be aware that any additional frames sent by the client or any Erlang messages waiting to be received will not be processed. Also note that when replying a list of frames that includes close, any frame found after the close frame will not be sent.</p>
-
-<h2 id="ping_and_timeout">Ping and timeout</h2>
-
-<p>The biggest performance improvement you can do when dealing with a huge number of Websocket connections is to reduce the number of timers that are started on the server. A common use of timers when dealing with connections is for sending a ping every once in a while. This should be done exclusively on the client side. Indeed, a server handling one million Websocket connections will perform a lot better when it doesn't have to handle one million extra timers too!</p>
-
-<p>Cowboy will automatically respond to ping frames sent by the client. It will still forward the frame to the handler for informative purpose, but no further action is required.</p>
-
-<p>Cowboy can be configured to automatically close the Websocket connection when no data arrives on the socket. It is highly recommended to configure a timeout for it, as otherwise you may end up with zombie "half-connected" sockets that may leave the process alive forever.</p>
-
-<p>A good timeout value is 60 seconds.</p>
-
-<script type="syntaxhighlighter" class="brush: erlang"><![CDATA[
-websocket_init(_Type, Req, _Opts) ->
-	{ok, Req, #state{}, 60000}.
-]]></script>
-
-<p>This value cannot be changed once it is set. It defaults to <code>infinity</code>.</p>
-
-<h2 id="hibernate">Hibernate</h2>
-
-<p>Most tuples returned from handler callbacks can include an extra value <code>hibernate</code>. After doing any necessary operations following the return of the callback, Cowboy will hibernate the process.</p>
-
-<p>It is highly recommended to hibernate processes that do not handle much traffic. It is a good idea to hibernate all connections by default and investigate only when you start noticing increased CPU usage.</p>
-
-<h2 id="supporting_older_browsers">Supporting older browsers</h2>
-
-<p>Unfortunately Websocket is a relatively recent technology, which means that not all browsers support it. A library like <a href="https://github.com/extend/bullet">Bullet</a> can be used to emulate Websocket connections on older browsers.</p>

-
-<p>This chapter explains what Websocket is and why it is a vital component of soft realtime Web applications.</p>
-
-<h2 id="description">Description</h2>
-
-<p>Websocket is an extension to HTTP that emulates plain TCP connections between the client, typically a Web browser, and the server. It uses the HTTP Upgrade mechanism to establish the connection.</p>
-
-<p>Websocket connections are asynchronous, unlike HTTP. This means that not only can the client send frames to the server at any time, but the server can also send frames to the client without the client initiating anything other than the Websocket connection itself. This allows the server to push data to the client directly.</p>
-
-<p>Websocket is an IETF standard. Cowboy supports the standard and all drafts that were previously implemented by browsers, excluding the initial flawed draft sometimes known as "version 0".</p>
-
-<h2 id="implementation">Implementation</h2>
-
-<p>Cowboy implements Websocket as a protocol upgrade. Once the upgrade is performed from the <code>init/3</code> callback, Cowboy switches to Websocket. Please consult the next chapter for more information on initiating and handling Websocket connections.</p>
-
-<p>The implementation of Websocket in Cowboy is validated using the Autobahn test suite, which is an extensive suite of tests covering all aspects of the protocol. Cowboy passes the suite with 100% success, including all optional tests.</p>
-
-<p>Cowboy's Websocket implementation also includes the x-webkit-deflate-frame compression draft which is being used by some browsers to reduce the size of data being transmitted. Cowboy will automatically use compression as long as the <code>compress</code> protocol option is set when starting the listener.</p>

-<p>Small, fast, modular HTTP server.</p>
-
-<h2 id="dependencies">Dependencies</h2>
-
-<p>The <code>cowboy</code> application uses the Erlang applications <code>ranch</code> for listening and accepting TCP connections, <code>crypto</code> for establishing Websocket connections, and <code>cowlib</code> for parsing and building messages for Web protocols. These dependencies must be loaded for the <code>cowboy</code> application to work. In an embedded environment this means that they need to be started with the <code>application:start/{1,2}</code> function before the <code>cowboy</code> application is started.</p>
-
-<p>The <code>cowboy</code> application also uses the Erlang applications <code>asn1</code>, <code>public_key</code> and <code>ssl</code> when listening for HTTPS connections. These are started automatically if they weren't before.</p>
-
-<h2 id="environment">Environment</h2>
-
-<p>The <code>cowboy</code> application does not define any application environment configuration parameters.</p>

-
-<p>The <code>cowboy_loop_handler</code> behaviour defines the interface used by HTTP handlers that do not send a response directly, instead requiring a receive loop to process Erlang messages.</p>
-
-<p>This interface is best fit for long-polling types of requests.</p>
-
-<p>The <code>init/3</code> callback will always be called, followed by zero or more calls to <code>info/3</code>. The <code>terminate/3</code> callback will always be called last.</p>

-
-<p>Types:</p>
-
-<ul>
-<li>TransportName = tcp | ssl | atom()</li>
-<li>ProtocolName = http | atom()</li>
-<li>Req = cowboy_req:req()</li>
-<li>Opts = any()</li>
-<li>State = any()</li>
-<li>Timeout = timeout()</li>
-</ul>
-
-<p>Initialize the state for this request.</p>
-
-<p>This callback will typically be used to register this process to an event manager or a message queue in order to receive the messages the handler wants to process.</p>
-
-<p>The receive loop will run for a duration of up to <code>Timeout</code> milliseconds after it last received data from the socket, at which point it will stop and send a <code>204 No Content</code> reply. By default this value is set to <code>infinity</code>. It is recommended to either set this value or ensure by any other mechanism that the handler will be closed after a certain period of inactivity.</p>
-
-<p>The <code>hibernate</code> option will hibernate the process until it starts receiving messages.</p>
-
-<p>The <code>shutdown</code> return value can be used to skip the receive loop entirely.</p>

-<li>Info = any()</li>
-<li>Req = cowboy_req:req()</li>
-<li>State = any()</li>
-</ul>
-
-<p>Handle the Erlang message received.</p>
-
-<p>This function will be called every time an Erlang message has been received. The message can be any Erlang term.</p>
-
-<p>The <code>ok</code> return value can be used to stop the receive loop, typically because a response has been sent.</p>
-
-<p>The <code>hibernate</code> option will hibernate the process until it receives another message.</p>
-
-<h3 id="terminate">terminate(Reason, Req, State) -> ok</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>Reason = {normal, shutdown} | {normal, timeout} | {error, closed} | {error, overflow} | {error, atom()}</li>
-<li>Req = cowboy_req:req()</li>
-<li>State = any()</li>
-</ul>
-
-<p>Perform any necessary cleanup of the state.</p>
-
-<p>This callback will typically unregister from any event manager or message queue it registered to in <code>init/3</code>.</p>
-
-<p>This callback should release any resource currently in use, clear any active timer and reset the process to its original state, as it might be reused for future requests sent on the same connection.</p>

-
-<p>The <code>cowboy_middleware</code> behaviour defines the interface used by Cowboy middleware modules.</p>
-
-<p>Middlewares process the request sequentially in the order they are configured.</p>
-
-<h2 id="types">Types</h2>
-
-<h3 id="env">env() = [{atom(), any()}]</h3>
-
-<p>The environment variable.</p>
-
-<p>One is created for every request. It is passed to each middleware module executed and subsequently returned, optionally with its contents modified.</p>
-
-<h2 id="callbacks">Callbacks</h2>
-
-<h3 id="execute">execute(Req, Env) -> {ok, Req, Env} | {suspend, Module, Function, Args} | {halt, Req} | {error, StatusCode, Req}</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>Req = cowboy_req:req()</li>
-<li>Env = env()</li>
-<li>Module = module()</li>
-<li>Function = atom()</li>
-<li>Args = [any()]</li>
-<li>StatusCode = cowboy:http_status()</li>
-</ul>
-
-<p>Execute the middleware.</p>
-
-<p>The <code>ok</code> return value indicates that everything went well and that Cowboy should continue processing the request. A response may or may not have been sent.</p>
-
-<p>The <code>suspend</code> return value will hibernate the process until an Erlang message is received. Note that when resuming, any previous stacktrace information will be gone.</p>
-
-<p>The <code>halt</code> return value stops Cowboy from doing any further processing of the request, even if there are middlewares that haven't been executed yet. The connection may be left open to receive more requests from the client.</p>
-
-<p>The <code>error</code> return value sends an error response identified by the <code>StatusCode</code> and then proceeds to terminate the connection. Middlewares that haven't been executed yet will not be called.</p>

-
-<p>The <code>cowboy_req</code> module provides functions to access, manipulate and respond to requests.</p>
-
-<p>The functions in this module follow patterns for their return types, based on the kind of function.</p>
-
-<ul>
-<li>access: <code>{Value, Req}</code></li>
-<li>action: <code>{Result, Req} | {Result, Value, Req} | {error, atom()}</code></li>
-<li>modification: <code>Req</code></li>
-<li>question: <code>boolean()</code></li>
-</ul>
-
-<p>The only exception is the <code>chunk/2</code> function which may return <code>ok</code>.</p>
-
-<p>Whenever <code>Req</code> is returned, you must use this returned value and ignore any previous you may have had. This value contains various state informations which are necessary for Cowboy to do some lazy evaluation or cache results where appropriate.</p>
-
-<p>All functions which perform an action should only be called once. This includes reading the request body or replying. Cowboy will generally throw an error on the second call.</p>
-
-<p>It is highly discouraged to pass the Req object to another process. Doing so and calling <code>cowboy_req</code> functions from it leads to undefined behavior.</p>
-
-<h2 id="types">Types</h2>
-
-<h3 id="body_opts">body_opts() = [{continue, boolean()} | {length, non_neg_integer()} | {read_length, non_neg_integer()} | {read_timeout, timeout()} | {transfer_decode, transfer_decode_fun(), any()} | {content_decode, content_decode_fun()}]</h3>

-
-<p>Types:</p>
-
-<ul>
-<li>HostURL = binary() | undefined</li>
-</ul>
-
-<p>Return the requested URL excluding the path component.</p>
-
-<p>This function will always return <code>undefined</code> until the <code>cowboy_router</code> middleware has been executed. This includes the <code>onrequest</code> hook.</p>
-

-
-<p>Parse the given header.</p>
-
-<p>While header names are case insensitive, this function expects the name to be a lowercase binary.</p>
-
-<p>The <code>parse_header/2</code> function will call <code>parser_header/3</code> with a different default value depending on the header being parsed. The following table summarizes the default values used.</p>
-

-</table>
-
-<p>Types for the above table:</p>
-
-<ul>
-<li>Type = SubType = Charset = Encoding = LanguageTag = binary()</li>
-<li>AuthType = Expect = OpaqueTag = Unit = binary()</li>
-<li>Params = ContentTypeParams = [{binary(), binary()}]</li>

-<li>Credentials - see below</li>
-<li>Range = {non_neg_integer(), non_neg_integer() | infinity} | neg_integer()</li>
-</ul>
-
-<p>The cookie names and values, the values of the sec-websocket-protocol and x-forwarded-for headers, the values in <code>AcceptExt</code> and <code>Params</code>, the authorization <code>Credentials</code>, the <code>ExpectValue</code> and <code>OpaqueTag</code> are case sensitive. All values in <code>ContentTypeParams</code> are case sensitive except the value of the charset parameter, which is case insensitive. All other values are case insensitive and will be returned as lowercase.</p>
-
-<p>The headers accept, accept-encoding and cookie headers can return an empty list. Others will return <code>{error, badarg}</code> if the header value is empty.</p>
-
-<p>The authorization header parsing code currently only supports basic HTTP authentication. The <code>Credentials</code> type is thus <code>{Username, Password}</code> with <code>Username</code> and <code>Password</code> being <code>binary()</code>.</p>
-
-<p>The range header value <code>Range</code> can take three forms:</p>
-
-<ul>
-<li><code>{From, To}</code>: from <code>From</code> to <code>To</code> units</li>
-<li><code>{From, infinity}</code>: everything after <code>From</code> units</li>
-<li><code>-Final</code>: the final <code>Final</code> units</li>
-</ul>
-
-<p>An <code>undefined</code> tuple will be returned if Cowboy doesn't know how to parse the requested header.</p>

-
-<p>Types:</p>
-
-<ul>
-<li>Path = binary()</li>

-
-<p>Types:</p>
-
-<ul>
-<li>Port = inet:port_number()</li>
-</ul>
-
-<p>Return the request's port.</p>
-
-<p>The port returned by this function is obtained by parsing the host header. It may be different than the actual port the client used to connect to the Cowboy server.</p>
-
-<h3 id="qs">qs(Req) -> {QueryString, Req2}</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>QueryString = binary()</li>
-</ul>
-
-<p>Return the request's query string.</p>
-
-<h3 id="qs_val">qs_val(Name, Req) -> qs_val(Name, Req, undefined)</h3>

-<li>Value = binary() | true</li>
-</ul>
-
-<p>Return a value from the request's query string.</p>
-
-<p>The value <code>true</code> will be returned when the name was found in the query string without an associated value.</p>
-
-<h3 id="qs_vals">qs_vals(Req) -> {[{Name, Value}], Req2}</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>Name = binary()</li>
-<li>Value = binary() | true</li>
-</ul>
-
-<p>Return the request's query string as a list of tuples.</p>

-
-<p>Types:</p>
-
-<ul>
-<li>URL = binary() | undefined</li>
-</ul>
-
-<p>Return the requested URL.</p>
-
-<p>This function will always return <code>undefined</code> until the <code>cowboy_router</code> middleware has been executed. This includes the <code>onrequest</code> hook.</p>
-

-
-<p>Types:</p>
-
-<ul>
-<li>Version = cowboy:http_version()</li>
-</ul>
-
-<p>Return the HTTP version used for this request.</p>
-
-<h2 id="request_body_related_exports">Request body related exports</h2>
-
-<h3 id="body">body(Req) -> body(Req, [])</h3>
-
-<h3 id="body">body(Req, Opts) -> {ok, Data, Req2} | {more, Data, Req2} | {error, Reason}</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>Opts = [body_opt()]</li>
-<li>Data = binary()</li>
-<li>Reason = atom()</li>
-</ul>
-
-<p>Read the request body.</p>
-
-<p>This function will read a chunk of the request body. If there is more data to be read after this function call, then a <code>more</code> tuple is returned. Otherwise an <code>ok</code> tuple is returned.</p>
-
-<p>Cowboy will automatically send a <code>100 Continue</code> reply if required. If this behavior is not desirable, it can be disabled by setting the <code>continue</code> option to <code>false</code>.</p>
-
-<p>Cowboy will by default attempt to read up to 8MB of the body, but in chunks of 1MB. It will use a timeout of 15s per chunk. All these values can be changed using the <code>length</code>, <code>read_length</code> and <code>read_timeout</code> options respectively. Note that the size of the data may not be the same as requested as the decoding functions may grow or shrink it, and Cowboy makes not attempt at returning an exact amount.</p>
-
-<p>Cowboy will properly handle chunked transfer-encoding by default. If any other transfer-encoding or content-encoding has been used for the request, custom decoding functions can be used. The <code>content_decode</code> and <code>transfer_decode</code> options allow setting the decode functions manually.</p>
-
-<p>After the body has been streamed fully, Cowboy will remove the transfer-encoding header from the Req object, and add the content-length header if it wasn't already there.</p>
-
-<p>This function can only be called once. Cowboy will not cache the result of this call.</p>
-
-<h3 id="body_length">body_length(Req) -> {Length, Req2}</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>Length = non_neg_integer() | undefined</li>
-</ul>
-
-<p>Return the length of the request body.</p>
-
-<p>The length will only be returned if the request does not use any transfer-encoding and if the content-length header is present.</p>
-
-<h3 id="body_qs">body_qs(Req) -> body_qs(Req, [{length, 64000}, {read_length, 64000}, {read_timeout, 5000}])</h3>
-
-<h3 id="body_qs">body_qs(Req, Opts) -> {ok, [{Name, Value}], Req2} | {badlength, Req2} | {error, Reason}</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>Opts = [body_opt()]</li>
-<li>Name = binary()</li>
-<li>Value = binary() | true</li>
-<li>Reason = chunked | badlength | atom()</li>
-</ul>
-
-<p>Return the request body as a list of tuples.</p>
-
-<p>This function will parse the body assuming the content-type application/x-www-form-urlencoded, commonly used for the query string.</p>
-
-<p>This function calls <code>body/2</code> for reading the body, with the same options it received. By default it will attempt to read a body of 64KB in one chunk, with a timeout of 5s. If the body is larger then a <code>badlength</code> tuple is returned.</p>
-
-<p>This function can only be called once. Cowboy will not cache the result of this call.</p>
-
-<h3 id="has_body">has_body(Req) -> boolean()</h3>
-
-<p>Return whether the request has a body.</p>
-
-<h3 id="part">part(Req) -> part(Req, [{length, 64000}, {read_length, 64000}, {read_timeout, 5000}])</h3>
-
-<h3 id="part">part(Req, Opts) -> {ok, Headers, Req2} | {done, Req2}</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>Opts = [body_opt()]</li>
-<li>Headers = cow_multipart:headers()</li>
-</ul>
-
-<p>Read the headers for the next part of the multipart message.</p>
-
-<p>Cowboy will skip any data remaining until the beginning of the next part. This includes the preamble to the multipart message but also the body of a previous part if it hasn't been read. Both are skipped automatically when calling this function.</p>
-
-<p>The headers returned are MIME headers, NOT HTTP headers. They can be parsed using the functions from the <code>cow_multipart</code> module. In addition, the <code>cow_multipart:form_data/1</code> function can be used to quickly figure out <code>multipart/form-data</code> messages. It takes the list of headers and returns whether this part is a simple form field or a file being uploaded.</p>
-
-<p>Note that once a part has been read, or skipped, it cannot be read again.</p>
-
-<p>This function calls <code>body/2</code> for reading the body, with the same options it received. By default it will only read chunks of 64KB with a timeout of 5s. This is tailored for reading part headers, not for skipping the previous part's body. You might want to consider skipping large parts manually.</p>
-
-<h3 id="part_body">part_body(Req) -> part_body(Req, [])</h3>
-
-<h3 id="part_body">part_body(Req, Opts) -> {ok, Data, Req2} | {more, Data, Req2}</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>Opts = [body_opt()]</li>
-<li>Data = binary()</li>
-</ul>
-
-<p>Read the body of the current part of the multipart message.</p>
-
-<p>This function calls <code>body/2</code> for reading the body, with the same options it received. It uses the same defaults.</p>
-
-<p>If there are more data to be read from the socket for this part, the function will return what it could read inside a <code>more</code> tuple. Otherwise, it will return an <code>ok</code> tuple.</p>
-
-<p>Calling this function again after receiving a <code>more</code> tuple will return another chunk of body. The last chunk will be returned inside an <code>ok</code> tuple.</p>
-
-<p>Note that once the body has been read, fully or partially, it cannot be read again.</p>

-<h2 id="response_related_exports">Response related exports</h2>
-
-<h3 id="chunk">chunk(Data, Req) -> ok | {error, Reason}</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>Data = iodata()</li>
-<li>Reason = atom()</li>
-</ul>
-
-<p>Send a chunk of data.</p>
-
-<p>This function should be called as many times as needed to send data chunks after calling <code>chunked_reply/{2,3}</code>.</p>
-
-<p>When the method is HEAD, no data will actually be sent.</p>
-
-<p>If the request uses HTTP/1.0, the data is sent directly without wrapping it in an HTTP/1.1 chunk, providing compatibility with older clients.</p>
-
-<h3 id="chunked_reply">chunked_reply(StatusCode, Req) -> chunked_reply(StatusCode, [], Req)</h3>
-
-<h3 id="chunked_reply">chunked_reply(StatusCode, Headers, Req) -> {ok, Req2}</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>StatusCode = cowboy:http_status()</li>
-<li>Headers = cowboy:http_headers()</li>
-</ul>
-
-<p>Send a response using chunked transfer-encoding.</p>
-
-<p>This function effectively sends the response status line and headers to the client.</p>
-
-<p>This function will not send any body set previously. After this call the handler must use the <code>chunk/2</code> function repeatedly to send the body in as many chunks as needed.</p>
-
-<p>If the request uses HTTP/1.0, the data is sent directly without wrapping it in an HTTP/1.1 chunk, providing compatibility with older clients.</p>
-
-<p>This function can only be called once, with the exception of overriding the response in the <code>onresponse</code> hook.</p>
-
-<h3 id="continue">continue(Req) -> ok | {error, Reason}</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>Reason = atom()</li>
-</ul>
-
-<p>Send a 100 Continue intermediate reply.</p>
-
-<p>This reply is required before the client starts sending the body when the request contains the <code>expect</code> header with the <code>100-continue</code> value.</p>
-
-<p>Cowboy will send this automatically when required. However you may want to do it manually by disabling this behavior with the <code>continue</code> body option and then calling this function.</p>
-
-<h3 id="delete_resp_header">delete_resp_header(Name, Req) -> Req2</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>Name = binary()</li>
-</ul>
-
-<p>Delete the given response header.</p>
-
-<p>While header names are case insensitive, this function expects the name to be a lowercase binary.</p>
-
-<h3 id="has_resp_body">has_resp_body(Req) -> boolean()</h3>
-
-<p>Return whether a response body has been set.</p>
-
-<p>This function will return false if a response body has been set with a length of 0.</p>
-
-<h3 id="has_resp_header">has_resp_header(Name, Req) -> boolean()</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>Name = binary()</li>
-</ul>
-
-<p>Return whether the given response header has been set.</p>
-
-<p>While header names are case insensitive, this function expects the name to be a lowercase binary.</p>
-
-<h3 id="reply">reply(StatusCode, Req) -> reply(StatusCode, [], Req)</h3>
-
-<h3 id="reply">reply(StatusCode, Headers, Req) - see below</h3>
-
-<h3 id="reply">reply(StatusCode, Headers, Body, Req) -> {ok, Req2}</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>StatusCode = cowboy:http_status()</li>
-<li>Headers = cowboy:http_headers()</li>
-<li>Body = iodata()</li>
-</ul>
-
-<p>Send a response.</p>
-
-<p>This function effectively sends the response status line, headers and body to the client, in a single send function call.</p>
-
-<p>The <code>reply/2</code> and <code>reply/3</code> functions will send the body set previously, if any. The <code>reply/4</code> function overrides any body set previously and sends <code>Body</code> instead.</p>
-
-<p>If a body function was set, and <code>reply/2</code> or <code>reply/3</code> was used, it will be called before returning.</p>
-
-<p>No more data can be sent to the client after this function returns.</p>
-
-<p>This function can only be called once, with the exception of overriding the response in the <code>onresponse</code> hook.</p>
-
-<h3 id="set_resp_body">set_resp_body(Body, Req) -> Req2</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>Body = iodata()</li>
-</ul>
-
-<p>Set a response body.</p>
-
-<p>This body will not be sent if <code>chunked_reply/{2,3}</code> or <code>reply/4</code> is used, as they override it.</p>
-
-<h3 id="set_resp_body_fun">set_resp_body_fun(Fun, Req) -> Req2</h3>
-
-<h3 id="set_resp_body_fun">set_resp_body_fun(Length, Fun, Req) -> Req2</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>Fun = fun((Socket, Transport) -> ok)</li>
-<li>Socket = inet:socket()</li>
-<li>Transport = module()</li>
-<li>Length = non_neg_integer()</li>
-</ul>
-
-<p>Set a fun for sending the response body.</p>
-
-<p>If a <code>Length</code> is provided, it will be sent in the content-length header in the response. It is recommended to set the length if it can be known in advance. Otherwise, the transfer-encoding header will be set to identity.</p>
-
-<p>This function will only be called if the response is sent using the <code>reply/2</code> or <code>reply/3</code> function.</p>
-
-<p>The fun will receive the Ranch <code>Socket</code> and <code>Transport</code> as arguments. Only send and sendfile operations are supported.</p>
-
-<h3 id="set_resp_body_fun">set_resp_body_fun(chunked, Fun, Req) -> Req2</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>Fun = fun((ChunkFun) -> ok)</li>
-<li>ChunkFun = fun((iodata()) -> ok | {error, atom()})</li>
-</ul>
-
-<p>Set a fun for sending the response body using chunked transfer-encoding.</p>
-
-<p>This function will only be called if the response is sent using the <code>reply/2</code> or <code>reply/3</code> function.</p>
-
-<p>The fun will receive another fun as argument. This fun is to be used to send chunks in a similar way to the <code>chunk/2</code> function, except the fun only takes one argument, the data to be sent in the chunk.</p>
-
-<h3 id="set_resp_cookie">set_resp_cookie(Name, Value, Opts, Req) -> Req2</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>Name = iodata()</li>
-<li>Value = iodata()</li>
-<li>Opts = cookie_opts()</li>
-</ul>
-
-<p>Set a cookie in the response.</p>
-
-<p>Cookie names are case sensitive.</p>
-
-<h3 id="set_resp_header">set_resp_header(Name, Value, Req) -> Req2</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>Name = binary()</li>
-<li>Value = iodata()</li>
-</ul>
-
-<p>Set a response header.</p>
-
-<p>You should use <code>set_resp_cookie/4</code> instead of this function to set cookies.</p>
-
-<h2 id="misc._exports">Misc. exports</h2>
-
-<h3 id="compact">compact(Req) -> Req2</h3>
-
-<p>Remove any non-essential data from the Req object.</p>
-
-<p>Long-lived connections usually only need to manipulate the Req object at initialization. Compacting allows saving up memory by discarding extraneous information.</p>

-<p>The <code>cowboy_rest</code> module implements REST semantics on top of the HTTP protocol.</p>
-
-<p>This module cannot be described as a behaviour due to most of the callbacks it defines being optional. It has the same semantics as a behaviour otherwise.</p>
-
-<p>The only mandatory callback is <code>init/3</code>, needed to perform the protocol upgrade.</p>
-

-
-<p>Type: {binary(), binary(), '*' | [{binary(), binary()}]}</p>
-
-<p>Negotiated media-type.</p>
-
-<p>The media-type is the content-type, excluding the charset.</p>
-
-<p>This value is always defined after the call to <code>content_types_provided/2</code>.</p>
-
-<h2 id="callbacks">Callbacks</h2>
-
-<h3 id="init">init({TransportName, ProtocolName}, Req, Opts) -> {upgrade, protocol, cowboy_rest} | {upgrade, protocol, cowboy_rest, Req, Opts}</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>TransportName = tcp | ssl | atom()</li>
-<li>ProtocolName = http | atom()</li>
-<li>Req = cowboy_req:req()</li>
-<li>Opts = any()</li>
-</ul>
-
-<p>Upgrade the protocol to <code>cowboy_rest</code>.</p>
-
-<p>This is the only mandatory callback.</p>
-
-<h3 id="rest_init">rest_init(Req, Opts) -> {ok, Req, State}</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>Req = cowboy_req:req()</li>
-<li>Opts = any()</li>
-<li>State = any()</li>
-</ul>
-
-<p>Initialize the state for this request.</p>
-
-<h3 id="rest_terminate">rest_terminate(Req, State) -> ok</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>Req = cowboy_req:req()</li>
-<li>State = any()</li>
-</ul>
-
-<p>Perform any necessary cleanup of the state.</p>
-
-<p>This callback should release any resource currently in use, clear any active timer and reset the process to its original state, as it might be reused for future requests sent on the same connection.</p>
-
-<h3 id="callback">Callback(Req, State) -> {Value, Req, State} | {halt, Req, State}</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>Callback - one of the REST callbacks described below</li>
-<li>Req = cowboy_req:req()</li>
-<li>State = any()</li>
-<li>Value - see the REST callbacks description below</li>
-</ul>
-
-<p>Please see the REST callbacks description below for details on the <code>Value</code> type, the default value if the callback is not defined, and more general information on when the callback is called and what its intended use is.</p>
-
-<p>The <code>halt</code> tuple can be returned to stop REST processing. It is up to the resource code to send a reply before that, otherwise a <code>204 No Content</code> will be sent.</p>

-
-<h3 id="allowed_methods">allowed_methods</h3>
-
-<ul>
-<li>Methods: all</li>
-<li>Value type: [binary()]</li>
-<li>Default value: [<<"GET">>, <<"HEAD">>, <<"OPTIONS">>]</li>
-</ul>
-
-<p>Return the list of allowed methods.</p>
-
-<p>Methods are case sensitive. Standard methods are always uppercase.</p>
-
-<h3 id="allow_missing_post">allow_missing_post</h3>
-
-<ul>
-<li>Methods: POST</li>
-<li>Value type: boolean()</li>
-<li>Default value: true</li>
-</ul>
-
-<p>Return whether POST is allowed when the resource doesn't exist.</p>
-
-<p>Returning <code>true</code> here means that a new resource will be created. The URL to the created resource should also be returned from the <code>AcceptResource</code> callback.</p>
-
-<h3 id="charsets_provided">charsets_provided</h3>
-
-<ul>
-<li>Methods: GET, HEAD, POST, PUT, PATCH, DELETE</li>
-<li>Value type: [binary()]</li>
-<li>Skip to the next step if undefined</li>
-</ul>
-
-<p>Return the list of charsets the resource provides.</p>
-
-<p>The list must be ordered in order of preference.</p>
-
-<p>If the accept-charset header was not sent, the first charset in the list will be selected. Otherwise Cowboy will select the most appropriate charset from the list.</p>
-
-<p>The chosen charset will be set in the <code>Req</code> object as the meta value <code>charset</code>.</p>
-
-<p>While charsets are case insensitive, this callback is expected to return them as lowercase binary.</p>
-
-<h3 id="content_types_accepted">content_types_accepted</h3>
-
-<ul>
-<li>Methods: POST, PUT, PATCH</li>
-<li>No default</li>
-</ul>
-
-<p>Types:</p>
-
-<ul>
-<li>Value = [{binary() | {Type, SubType, Params}, AcceptResource}]</li>
-<li>Type = SubType = binary()</li>
-<li>Params = '*' | [{binary(), binary()}]</li>
-<li>AcceptResource = atom()</li>
-</ul>
-
-<p>Return the list of content-types the resource accepts.</p>
-
-<p>The list must be ordered in order of preference.</p>
-
-<p>Each content-type can be given either as a binary string or as a tuple containing the type, subtype and parameters.</p>
-
-<p>Cowboy will select the most appropriate content-type from the list. If any parameter is acceptable, then the tuple form should be used with parameters set to <code>'*'</code>. If the parameters value is set to <code>[]</code> only content-type values with no parameters will be accepted. All parameter values are treated in a case sensitive manner except the <code>charset</code> parameter, if present, which is case insensitive.</p>
-
-<p>This function will be called for POST, PUT and PATCH requests. It is entirely possible to define different callbacks for different methods if the handling of the request differs. Simply verify what the method is with <code>cowboy_req:method/1</code> and return a different list for each methods.</p>
-
-<p>The <code>AcceptResource</code> value is the name of the callback that will be called if the content-type matches. It is defined as follow.</p>
-
-<ul>
-<li>Value type: true | {true, URL} | false</li>
-<li>No default</li>
-</ul>
-
-<p>Process the request body.</p>
-
-<p>This function should create or update the resource with the information contained in the request body. This information may be full or partial depending on the request method.</p>
-
-<p>If the request body was processed successfully, <code>true</code> must be returned. If the request method is POST, <code>{true, URL}</code> may be returned instead, and Cowboy will redirect the client to the location of the newly created resource.</p>
-
-<p>If a response body must be sent, the appropriate media-type, charset and language can be retrieved using the <code>cowboy_req:meta/{2,3}</code> functions. The respective keys are <code>media_type</code>, <code>charset</code> and <code>language</code>. The body can be set using <code>cowboy_req:set_resp_body/2</code>.</p>
-
-<h3 id="content_types_provided">content_types_provided</h3>
-
-<ul>
-<li>Methods: GET, HEAD, POST, PUT, PATCH, DELETE</li>
-<li>Default value: [{{<<"text">>, <<"html">>, '*'}, to_html}]</li>
-</ul>
-
-<p>Types:</p>
-
-<ul>
-<li>Value = [{binary() | {Type, SubType, Params}, ProvideResource}]</li>
-<li>Type = SubType = binary()</li>
-<li>Params = '*' | [{binary(), binary()}]</li>
-<li>ProvideResource = atom()</li>
-</ul>
-
-<p>Return the list of content-types the resource provides.</p>
-
-<p>The list must be ordered in order of preference.</p>
-
-<p>Each content-type can be given either as a binary string or as a tuple containing the type, subtype and parameters.</p>
-
-<p>Cowboy will select the most appropriate content-type from the list. If any parameter is acceptable, then the tuple form should be used with parameters set to <code>'*'</code>. If the parameters value is set to <code>[]</code> only content-type values with no parameters will be accepted. All parameter values are treated in a case sensitive manner except the <code>charset</code> parameter, if present, which is case insensitive.</p>
-
-<p>The <code>ProvideResource</code> value is the name of the callback that will be called if the content-type matches. It will only be called when a representation of the resource needs to be returned. It is defined as follow.</p>
-
-<ul>
-<li>Methods: GET, HEAD</li>
-<li>Value type: iodata() | {stream, Fun} | {stream, Len, Fun} | {chunked, ChunkedFun}</li>
-<li>No default</li>
-</ul>
-
-<p>Return the response body.</p>
-
-<p>The response body may be provided directly or through a fun. If a fun tuple is returned, the appropriate <code>set_resp_body_fun</code> function will be called. Please refer to the documentation for these functions for more information about the types.</p>
-
-<p>The call to this callback happens a good time after the call to <code>content_types_provided/2</code>, when it is time to start rendering the response body.</p>
-
-<h3 id="delete_completed">delete_completed</h3>
-
-<ul>
-<li>Methods: DELETE</li>
-<li>Value type: boolean()</li>
-<li>Default value: true</li>
-</ul>
-
-<p>Return whether the delete action has been completed.</p>
-
-<p>This function should return <code>false</code> if there is no guarantee that the resource gets deleted immediately from the system, including from any internal cache.</p>
-
-<p>When this function returns <code>false</code>, a <code>202 Accepted</code> response will be sent instead of a <code>200 OK</code> or <code>204 No Content</code>.</p>
-
-<h3 id="delete_resource">delete_resource</h3>
-
-<ul>
-<li>Methods: DELETE</li>
-<li>Value type: boolean()</li>
-<li>Default value: false</li>
-</ul>
-
-<p>Delete the resource.</p>
-
-<p>The value returned indicates if the action was successful, regardless of whether the resource is immediately deleted from the system.</p>
-
-<h3 id="expires">expires</h3>
-
-<ul>
-<li>Methods: GET, HEAD</li>
-<li>Value type: calendar:datetime() | binary() | undefined</li>
-<li>Default value: undefined</li>
-</ul>
-
-<p>Return the date of expiration of the resource.</p>
-
-<p>This date will be sent as the value of the expires header.</p>
-
-<h3 id="forbidden">forbidden</h3>
-
-<ul>
-<li>Methods: all</li>
-<li>Value type: boolean()</li>
-<li>Default value: false</li>
-</ul>
-
-<p>Return whether access to the resource is forbidden.</p>
-
-<p>A <code>403 Forbidden</code> response will be sent if this function returns <code>true</code>. This status code means that access is forbidden regardless of authentication, and that the request shouldn't be repeated.</p>
-
-<h3 id="generate_etag">generate_etag</h3>
-
-<ul>
-<li>Methods: GET, HEAD, POST, PUT, PATCH, DELETE</li>
-<li>Value type: binary() | {weak | strong, binary()}</li>
-<li>Default value: undefined</li>
-</ul>
-
-<p>Return the entity tag of the resource.</p>
-
-<p>This value will be sent as the value of the etag header.</p>
-
-<p>If a binary is returned, then the value will be parsed to the tuple form automatically. The value must be in the same format as the etag header, including quotes.</p>
-
-<h3 id="is_authorized">is_authorized</h3>
-
-<ul>
-<li>Methods: all</li>
-<li>Value type: true | {false, AuthHeader}</li>
-<li>Default value: true</li>
-</ul>
-
-<p>Return whether the user is authorized to perform the action.</p>
-
-<p>This function should be used to perform any necessary authentication of the user before attempting to perform any action on the resource.</p>
-
-<p>If the authentication fails, the value returned will be sent as the value for the www-authenticate header in the <code>401 Unauthorized</code> response.</p>
-
-<h3 id="is_conflict">is_conflict</h3>
-
-<ul>
-<li>Methods: PUT</li>
-<li>Value type: boolean()</li>
-<li>Default value: false</li>
-</ul>
-
-<p>Return whether the put action results in a conflict.</p>
-
-<p>A <code>409 Conflict</code> response will be sent if this function returns <code>true</code>.</p>
-
-<h3 id="known_content_type">known_content_type</h3>
-
-<ul>
-<li>Methods: all</li>
-<li>Value type: boolean()</li>
-<li>Default value: true</li>
-</ul>
-
-<p>Return whether the content-type is known.</p>
-
-<p>This function determines if the server understands the content-type, regardless of its use by the resource.</p>
-
-<h3 id="known_methods">known_methods</h3>
-
-<ul>
-<li>Methods: all</li>
-<li>Value type: [binary()]</li>
-<li>Default value: [<<"GET">>, <<"HEAD">>, <<"POST">>, <<"PUT">>, <<"PATCH">>, <<"DELETE">>, <<"OPTIONS">>]</li>
-</ul>
-
-<p>Return the list of known methods.</p>
-
-<p>The full list of methods known by the server should be returned, regardless of their use in the resource.</p>
-
-<p>The default value lists the methods Cowboy knows and implement in <code>cowboy_rest</code>.</p>
-
-<p>Methods are case sensitive. Standard methods are always uppercase.</p>
-
-<h3 id="languages_provided">languages_provided</h3>
-
-<ul>
-<li>Methods: GET, HEAD, POST, PUT, PATCH, DELETE</li>
-<li>Value type: [binary()]</li>
-<li>Skip to the next step if undefined</li>
-</ul>
-
-<p>Return the list of languages the resource provides.</p>
-
-<p>The list must be ordered in order of preference.</p>
-
-<p>If the accept-language header was not sent, the first language in the list will be selected. Otherwise Cowboy will select the most appropriate language from the list.</p>
-
-<p>The chosen language will be set in the <code>Req</code> object as the meta value <code>language</code>.</p>
-
-<p>While languages are case insensitive, this callback is expected to return them as lowercase binary.</p>
-
-<h3 id="last_modified">last_modified</h3>
-
-<ul>
-<li>Methods: GET, HEAD, POST, PUT, PATCH, DELETE</li>
-<li>Value type: calendar:datetime()</li>
-<li>Default value: undefined</li>
-</ul>
-
-<p>Return the date of last modification of the resource.</p>
-
-<p>This date will be used to test against the if-modified-since and if-unmodified-since headers, and sent as the last-modified header in the response of GET and HEAD requests.</p>
-
-<h3 id="malformed_request">malformed_request</h3>
-
-<ul>
-<li>Methods: all</li>
-<li>Value type: boolean()</li>
-<li>Default value: false</li>
-</ul>
-
-<p>Return whether the request is malformed.</p>
-
-<p>Cowboy has already performed all the necessary checks by the time this function is called, so few resources are expected to implement it.</p>
-
-<p>The check is to be done on the request itself, not on the request body, which is processed later.</p>
-
-<h3 id="moved_permanently">moved_permanently</h3>
-
-<ul>
-<li>Methods: GET, HEAD, POST, PUT, PATCH, DELETE</li>
-<li>Value type: {true, URL} | false</li>
-<li>Default value: false</li>
-</ul>
-
-<p>Return whether the resource was permanently moved.</p>
-
-<p>If it was, its new URL is also returned and sent in the location header in the response.</p>
-
-<h3 id="moved_temporarily">moved_temporarily</h3>
-
-<ul>
-<li>Methods: GET, HEAD, POST, PATCH, DELETE</li>
-<li>Value type: {true, URL} | false</li>
-<li>Default value: false</li>
-</ul>
-
-<p>Return whether the resource was temporarily moved.</p>
-
-<p>If it was, its new URL is also returned and sent in the location header in the response.</p>
-
-<h3 id="multiple_choices">multiple_choices</h3>
-
-<ul>
-<li>Methods: GET, HEAD, POST, PUT, PATCH, DELETE</li>
-<li>Value type: boolean()</li>
-<li>Default value: false</li>
-</ul>
-
-<p>Return whether there are multiple representations of the resource.</p>
-
-<p>This function should be used to inform the client if there are different representations of the resource, for example different content-type. If this function returns <code>true</code>, the response body should include information about these different representations using <code>cowboy_req:set_resp_body/2</code>. The content-type of the response should be the one previously negociated and that can be obtained by calling <code>cowboy_req:meta(media_type, Req)</code>.</p>
-
-<h3 id="options">options</h3>
-
-<ul>
-<li>Methods: OPTIONS</li>
-<li>Value type: ok</li>
-<li>Default value: ok</li>
-</ul>
-
-<p>Handle a request for information.</p>
-
-<p>The response should inform the client the communication options available for this resource.</p>
-
-<p>By default, Cowboy will send a <code>200 OK</code> response with the allow header set.</p>
-
-<h3 id="previously_existed">previously_existed</h3>
-
-<ul>
-<li>Methods: GET, HEAD, POST, PATCH, DELETE</li>
-<li>Value type: boolean()</li>
-<li>Default value: false</li>
-</ul>
-
-<p>Return whether the resource existed previously.</p>
-
-<h3 id="resource_exists">resource_exists</h3>
-
-<ul>
-<li>Methods: GET, HEAD, POST, PUT, PATCH, DELETE</li>
-<li>Value type: boolean()</li>
-<li>Default value: true</li>
-</ul>
-
-<p>Return whether the resource exists.</p>
-
-<p>If it exists, conditional headers will be tested before attempting to perform the action. Otherwise, Cowboy will check if the resource previously existed first.</p>
-
-<h3 id="service_available">service_available</h3>
-
-<ul>
-<li>Methods: all</li>
-<li>Value type: boolean()</li>
-<li>Default value: true</li>
-</ul>
-
-<p>Return whether the service is available.</p>
-
-<p>This function can be used to test that all relevant backend systems are up and able to handle requests.</p>
-
-<p>A <code>503 Service Unavailable</code> response will be sent if this function returns <code>false</code>.</p>
-
-<h3 id="uri_too_long">uri_too_long</h3>
-
-<ul>
-<li>Methods: all</li>
-<li>Value type: boolean()</li>
-<li>Default value: false</li>
-</ul>
-
-<p>Return whether the requested URI is too long.</p>
-
-<p>Cowboy has already performed all the necessary checks by the time this function is called, so few resources are expected to implement it.</p>
-
-<p>A <code>414 Request-URI Too Long</code> response will be sent if this function returns <code>true</code>.</p>
-
-<h3 id="valid_content_headers">valid_content_headers</h3>
-
-<ul>
-<li>Methods: all</li>
-<li>Value type: boolean()</li>
-<li>Default value: true</li>
-</ul>
-
-<p>Return whether the content-* headers are valid.</p>
-
-<p>This also applies to the transfer-encoding header. This function must return <code>false</code> for any unknown content-* headers, or if the headers can't be understood. The function <code>cowboy_req:parse_header/2</code> can be used to quickly check the headers can be parsed.</p>
-
-<p>A <code>501 Not Implemented</code> response will be sent if this function returns <code>false</code>.</p>
-
-<h3 id="valid_entity_length">valid_entity_length</h3>
-
-<ul>
-<li>Methods: all</li>
-<li>Value type: boolean()</li>
-<li>Default value: true</li>
-</ul>
-
-<p>Return whether the request body length is within acceptable boundaries.</p>
-
-<p>A <code>413 Request Entity Too Large</code> response will be sent if this function returns <code>false</code>.</p>
-
-<h3 id="variances">variances</h3>
-
-<ul>
-<li>Methods: GET, HEAD, POST, PUT, PATCH, DELETE</li>
-<li>Value type: [binary()]</li>
-<li>Default value: []</li>
-</ul>
-
-<p>Return the list of headers that affect the representation of the resource.</p>
-
-<p>These request headers return the same resource but with different parameters, like another language or a different content-type.</p>
-
-<p>Cowboy will automatically add the accept, accept-language and accept-charset headers to the list if the respective functions were defined in the resource.</p>
-
-<p>This operation is performed right before the <code>resource_exists/2</code> callback. All responses past that point will contain the vary header which holds this list.</p>

-
-<p>The <code>cowboy_websocket_handler</code> behaviour defines the interface used by Websocket handlers.</p>
-
-<p>The <code>init/3</code> and <code>websocket_init/3</code> callbacks will always be called, followed by zero or more calls to <code>websocket_handle/3</code> and <code>websocket_info/3</code>. The <code>websocket_terminate/3</code> will always be called last.</p>
-
-<h2 id="types">Types</h2>
-
-<p>None.</p>

-<h2 id="callbacks">Callbacks</h2>
-
-<h3 id="init">init({TransportName, ProtocolName}, Req, Opts) -> {upgrade, protocol, cowboy_websocket} | {upgrade, protocol, cowboy_websocket, Req, Opts}</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>TransportName = tcp | ssl | atom()</li>
-<li>ProtocolName = http | atom()</li>
-<li>Req = cowboy_req:req()</li>
-<li>Opts = any()</li>
-</ul>
-
-<p>Upgrade the protocol to <code>cowboy_websocket</code>.</p>
-
-<h3 id="websocket_init">websocket_init(TransportName, Req, Opts) -> {ok, Req, State} | {ok, Req, State, hibernate} | {ok, Req, State, Timeout} | {ok, Req, State, Timeout, hibernate} | {shutdown, Req}</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>TransportName = tcp | ssl | atom()</li>
-<li>Req = cowboy_req:req()</li>
-<li>Opts = any()</li>
-<li>State = any()</li>
-<li>Timeout = timeout()</li>
-</ul>
-
-<p>Initialize the state for this session.</p>
-
-<p>This function is called before the upgrade to Websocket occurs. It can be used to negotiate Websocket protocol extensions with the client. It will typically be used to register this process to an event manager or a message queue in order to receive the messages the handler wants to process.</p>
-
-<p>The connection will stay up for a duration of up to <code>Timeout</code> milliseconds after it last received data from the socket, at which point it will stop and close the connection. By default this value is set to <code>infinity</code>. It is recommended to either set this value or ensure by any other mechanism that the handler will be closed after a certain period of inactivity.</p>
-
-<p>The <code>hibernate</code> option will hibernate the process until it starts receiving either data from the Websocket connection or Erlang messages.</p>
-
-<p>The <code>shutdown</code> return value can be used to close the connection before upgrading to Websocket.</p>
-
-<h3 id="websocket_handle">websocket_handle(InFrame, Req, State) -> {ok, Req, State} | {ok, Req, State, hibernate} | {reply, OutFrame | [OutFrame], Req, State} | {reply, OutFrame | [OutFrame], Req, State, hibernate} | {shutdown, Req, State}</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>InFrame = {text | binary | ping | pong, binary()}</li>
-<li>Req = cowboy_req:req()</li>
-<li>State = any()</li>
-<li>OutFrame = cowboy_websocket:frame()</li>
-</ul>
-
-<p>Handle the data received from the Websocket connection.</p>
-
-<p>This function will be called every time data is received from the Websocket connection.</p>
-
-<p>The <code>shutdown</code> return value can be used to close the connection. A close reply will also result in the connection being closed.</p>
-
-<p>The <code>hibernate</code> option will hibernate the process until it receives new data from the Websocket connection or an Erlang message.</p>
-
-<h3 id="websocket_info">websocket_info(Info, Req, State) -> {ok, Req, State} | {ok, Req, State, hibernate} | {reply, OutFrame | [OutFrame], Req, State} | {reply, OutFrame | [OutFrame], Req, State, hibernate} | {shutdown, Req, State}</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>Info = any()</li>
-<li>Req = cowboy_req:req()</li>
-<li>State = any()</li>
-<li>OutFrame = cowboy_websocket:frame()</li>
-</ul>
-
-<p>Handle the Erlang message received.</p>
-
-<p>This function will be called every time an Erlang message has been received. The message can be any Erlang term.</p>
-
-<p>The <code>shutdown</code> return value can be used to close the connection. A close reply will also result in the connection being closed.</p>
-
-<p>The <code>hibernate</code> option will hibernate the process until it receives another message or new data from the Websocket connection.</p>
-
-<h3 id="websocket_terminate">websocket_terminate(Reason, Req, State) -> ok</h3>
-
-<p>Types:</p>
-
-<ul>
-<li>Reason = {normal, shutdown | timeout} | {remote, closed} | {remote, cowboy_websocket:close_code(), binary()} | {error, badencoding | badframe | closed | atom()}</li>
-<li>Req = cowboy_req:req()</li>
-<li>State = any()</li>
-</ul>
-
-<p>Perform any necessary cleanup of the state.</p>
-
-<p>The connection will be closed and the process stopped right after this call.</p>

-[[constraints]]
-== Constraints
-
-Constraints are validation and conversion functions applied
-to user input.
-
-They are used in various places in Cowboy, including the
-router and the `cowboy_req` match functions.
-
-=== Syntax
-
-Constraints are provided as a list of fields. For each field
-in the list, specific constraints can be applied, as well as
-a default value if the field is missing.
-
-A field can take the form of an atom `field`, a tuple with
-constraints `{field, Constraints}` or a tuple with constraints
-and a default value `{field, Constraints, Default}`.
-The `field` form indicates the field is mandatory.
-
-Note that when used with the router, only the second form
-makes sense, as it does not use the default and the field
-is always defined.
-
-Constraints for each field are provided as an ordered list
-of atoms or funs to apply. Built-in constraints are provided
-as atoms, while custom constraints are provided as funs.
-
-When multiple constraints are provided, they are applied in
-the order given. If the value has been modified by a constraint
-then the next one receives the new value.
-
-For example, the following constraints will first validate
-and convert the field `my_value` to an integer, and then
-check that the integer is positive:
-
-[source,erlang]
-----
-PositiveFun = fun
-    (_, V) when V > 0 ->
-        {ok, V};
-    (_, _) ->
-        {error, not_positive}
-end,
-{my_value, [int, PositiveFun]}.
-----
-
-We ignore the first fun argument in this snippet. We shouldn't.
-We will simply learn what it is later in this chapter.
-
-When there's only one constraint, it can be provided directly
-without wrapping it into a list:
-
-[source,erlang]
-----
-{my_value, int}
-----
-
-=== Built-in constraints
-
-Built-in constraints are specified as an atom:
-
-[cols="<,<",options="header"]
-|===
-| Constraint | Description
-| int        | Converts binary value to integer.
-| nonempty   | Ensures the binary value is non-empty.
-|===
-
-=== Custom constraints
-
-Custom constraints are specified as a fun. This fun takes
-two arguments. The first argument indicates the operation
-to be performed, and the second is the value. What the
-value is and what must be returned depends on the operation.
-
-Cowboy currently defines three operations. The operation
-used for validating and converting user input is the `forward`
-operation.
-
-[source,erlang]
-----
-int(forward, Value) ->
-    try
-        {ok, binary_to_integer(Value)}
-    catch _:_ ->
-        {error, not_an_integer}
-    end;
-----
-
-The value must be returned even if it is not converted
-by the constraint.
-
-The `reverse` operation does the opposite: it
-takes a converted value and changes it back to what the
-user input would have been.
-
-[source,erlang]
-----
-int(reverse, Value) ->
-	try
-		{ok, integer_to_binary(Value)}
-	catch _:_ ->
-		{error, not_an_integer}
-	end;
-----
-
-Finally, the `format_error` operation takes an error
-returned by any other operation and returns a formatted
-human-readable error message.
-
-[source,erlang]
-----
-int(format_error, {not_an_integer, Value}) ->
-	io_lib:format("The value ~p is not an integer.", [Value]).
-----
-
-Notice that for this case you get both the error and
-the value that was given to the constraint that produced
-this error.
-

-
-<p>Constraints are validation and conversion functions applied to user input.</p>
-<p>They are used in various places in Cowboy, including the router and the <code>cowboy_req</code> match functions.</p>
-<h2 id="_syntax">Syntax</h2>
-<p>Constraints are provided as a list of fields. For each field in the list, specific constraints can be applied, as well as a default value if the field is missing.</p>
-<p>A field can take the form of an atom <code>field</code>, a tuple with constraints <code>{field, Constraints}</code> or a tuple with constraints and a default value <code>{field, Constraints, Default}</code>. The <code>field</code> form indicates the field is mandatory.</p>
-<p>Note that when used with the router, only the second form makes sense, as it does not use the default and the field is always defined.</p>
-<p>Constraints for each field are provided as an ordered list of atoms or funs to apply. Built-in constraints are provided as atoms, while custom constraints are provided as funs.</p>
-<p>When multiple constraints are provided, they are applied in the order given. If the value has been modified by a constraint then the next one receives the new value.</p>
-<p>For example, the following constraints will first validate and convert the field <code>my_value</code> to an integer, and then check that the integer is positive:</p>

-[[cookies]]
-== Using cookies
-
-Cookies are a mechanism allowing applications to maintain
-state on top of the stateless HTTP protocol.
-
-Cookies are a name/value store where the names and values are
-stored in plain text. They expire either after a delay
-or when the browser closes. They can be configured on a
-specific domain name or path, and restricted to secure
-resources (sent or downloaded over HTTPS), or restricted
-to the server (disallowing access from client-side scripts).
-
-Cookie names are de facto case sensitive.
-
-Cookies are stored client-side and sent with every subsequent
-request that matches the domain and path for which they were
-stored, until they expire. This can create a non-negligible
-cost.
-
-Cookies should not be considered secure. They are stored on
-the user's computer in plain text, and can be read by any
-program. They can also be read by proxies when using clear
-connections. Always validate the value before using it,
-and never store any sensitive information inside it.
-
-Cookies set by the server are only available in requests
-following the client reception of the response containing
-them.
-
-Cookies may be sent repeatedly. This is often useful to
-update the expiration time and avoid losing a cookie.
-
-=== Setting cookies
-
-By default cookies are defined for the duration of the session:
-
-[source,erlang]
-----
-SessionID = generate_session_id(),
-Req = cowboy_req:set_resp_cookie(<<"sessionid">>, SessionID, Req0).
-----
-
-They can also be set for a duration in seconds:
-
-[source,erlang]
-----
-SessionID = generate_session_id(),
-Req = cowboy_req:set_resp_cookie(<<"sessionid">>, SessionID, Req0,
-    #{max_age => 3600}).
-----
-
-To delete cookies, set `max_age` to 0:
-
-[source,erlang]
-----
-SessionID = generate_session_id(),
-Req = cowboy_req:set_resp_cookie(<<"sessionid">>, SessionID, Req0,
-    #{max_age => 0}).
-----
-
-To restrict cookies to a specific domain and path, the options
-of the same name can be used:
-
-[source,erlang]
-----
-Req = cowboy_req:set_resp_cookie(<<"inaccount">>, <<"1">>, Req0,
-    #{domain => "my.example.org", path => "/account"}).
-----
-
-Cookies will be sent with requests to this domain and all
-its subdomains, and to resources on this path or deeper
-in the path hierarchy.
-
-To restrict cookies to secure channels (typically resources
-available over HTTPS):
-
-[source,erlang]
-----
-SessionID = generate_session_id(),
-Req = cowboy_req:set_resp_cookie(<<"sessionid">>, SessionID, Req0,
-    #{secure => true}).
-----
-
-To prevent client-side scripts from accessing a cookie:
-
-[source,erlang]
-----
-SessionID = generate_session_id(),
-Req = cowboy_req:set_resp_cookie(<<"sessionid">>, SessionID, Req0,
-    #{http_only => true}).
-----
-
-Cookies may also be set client-side, for example using
-Javascript.
-
-=== Reading cookies
-
-The client only ever sends back the cookie name and value.
-All other options that can be set are never sent back.
-
-Cowboy provides two functions for reading cookies. Both
-involve parsing the cookie header(s) and so should not
-be called repeatedly.
-
-You can get all cookies as a key/value list:
-
-[source,erlang]
-Cookies = cowboy_req:parse_cookies(Req),
-{_, Lang} = lists:keyfind(<<"lang">>, 1, Cookies).
-
-Or you can perform a match against cookies and retrieve
-only the ones you need, while at the same time doing
-any required post processing using xref:constraints[constraints].
-This function returns a map:
-
-[source,erlang]
-#{id := ID, lang := Lang} = cowboy_req:match_cookies([id, lang], Req).
-
-You can use constraints to validate the values while matching
-them. The following snippet will crash if the `id` cookie is
-not an integer number or if the `lang` cookie is empty. Additionally
-the `id` cookie value will be converted to an integer term:
-
-[source,erlang]
-CookiesMap = cowboy_req:match_cookies([{id, int}, {lang, nonempty}], Req).
-
-Note that if two cookies share the same name, then the map value
-will be a list of the two cookie values.
-
-A default value can be provided. The default will be used
-if the `lang` cookie is not found. It will not be used if
-the cookie is found but has an empty value:
-
-[source,erlang]
-#{lang := Lang} = cowboy_req:match_cookies([{lang, [], <<"en-US">>}], Req).
-
-If no default is provided and the value is missing, an
-exception is thrown.

-<p>Cookies should not be considered secure. They are stored on the user&apos;s computer in plain text, and can be read by any program. They can also be read by proxies when using clear connections. Always validate the value before using it, and never store any sensitive information inside it.</p>
-<p>Cookies set by the server are only available in requests following the client reception of the response containing them.</p>
-<p>Cookies may be sent repeatedly. This is often useful to update the expiration time and avoid losing a cookie.</p>

-[[erlang_web]]
-== Erlang and the Web
-
-Erlang is the ideal platform for writing Web applications.
-Its features are a perfect match for the requirements of
-modern Web applications.
-
-=== The Web is concurrent
-
-When you access a website there is little concurrency
-involved. A few connections are opened and requests
-are sent through these connections. Then the web page
-is displayed on your screen. Your browser will only
-open up to 4 or 8 connections to the server, depending
-on your settings. This isn't much.
-
-But think about it. You are not the only one accessing
-the server at the same time. There can be hundreds, if
-not thousands, if not millions of connections to the
-same server at the same time.
-
-Even today a lot of systems used in production haven't
-solved the C10K problem (ten thousand concurrent connections).
-And the ones who did are trying hard to get to the next
-step, C100K, and are pretty far from it.
-
-Erlang meanwhile has no problem handling millions of
-connections. At the time of writing there are application
-servers written in Erlang that can handle more than two
-million connections on a single server in a real production
-application, with spare memory and CPU!
-
-The Web is concurrent, and Erlang is a language designed
-for concurrency, so it is a perfect match.
-
-Of course, various platforms need to scale beyond a few
-million connections. This is where Erlang's built-in
-distribution mechanisms come in. If one server isn't
-enough, add more! Erlang allows you to use the same code
-for talking to local processes or to processes in other
-parts of your cluster, which means you can scale very
-quickly if the need arises.
-
-The Web has large userbases, and the Erlang platform was
-designed to work in a distributed setting, so it is a
-perfect match.
-
-Or is it? Surely you can find solutions to handle that many
-concurrent connections with your favorite language... But all
-these solutions will break down in the next few years. Why?
-Firstly because servers don't get any more powerful, they
-instead get a lot more cores and memory. This is only useful
-if your application can use them properly, and Erlang is
-light-years away from anything else in that area. Secondly,
-today your computer and your phone are online, tomorrow your
-watch, goggles, bike, car, fridge and tons of other devices
-will also connect to various applications on the Internet.
-
-Only Erlang is prepared to deal with what's coming.
-
-=== The Web is soft real time
-
-What does soft real time mean, you ask? It means we want the
-operations done as quickly as possible, and in the case of
-web applications, it means we want the data propagated fast.
-
-In comparison, hard real time has a similar meaning, but also
-has a hard time constraint, for example an operation needs to
-be done in under N milliseconds otherwise the system fails
-entirely.
-
-Users aren't that needy yet, they just want to get access
-to their content in a reasonable delay, and they want the
-actions they make to register at most a few seconds after
-they submitted them, otherwise they'll start worrying about
-whether it successfully went through.
-
-The Web is soft real time because taking longer to perform an
-operation would be seen as bad quality of service.
-
-Erlang is a soft real time system. It will always run
-processes fairly, a little at a time, switching to another
-process after a while and preventing a single process to
-steal resources from all others. This means that Erlang
-can guarantee stable low latency of operations.
-
-Erlang provides the guarantees that the soft real time Web
-requires.
-
-=== The Web is asynchronous
-
-Long ago, the Web was synchronous because HTTP was synchronous.
-You fired a request, and then waited for a response. Not anymore.
-It all began when XmlHttpRequest started being used. It allowed
-the client to perform asynchronous calls to the server.
-
-Then Websocket appeared and allowed both the server and the client
-to send data to the other endpoint completely asynchronously. The
-data is contained within frames and no response is necessary.
-
-Erlang processes work the same. They send each other data contained
-within messages and then continue running without needing a response.
-They tend to spend most of their time inactive, waiting for a new
-message, and the Erlang VM happily activate them when one is received.
-
-It is therefore quite easy to imagine Erlang being good at receiving
-Websocket frames, which may come in at unpredictable times, pass the
-data to the responsible processes which are always ready waiting for
-new messages, and perform the operations required by only activating
-the required parts of the system.
-
-The more recent Web technologies, like Websocket of course, but also
-HTTP/2.0, are all fully asynchronous protocols. The concept
-of requests and responses is retained of course, but anything could
-be sent in between, by both the client or the browser, and the
-responses could also be received in a completely different order.
-
-Erlang is by nature asynchronous and really good at it thanks to the
-great engineering that has been done in the VM over the years. It's
-only natural that it's so good at dealing with the asynchronous Web.
-
-=== The Web is omnipresent
-
-The Web has taken a very important part of our lives. We're
-connected at all times, when we're on our phone, using our computer,
-passing time using a tablet while in the bathroom... And this
-isn't going to slow down, every single device at home or on us
-will be connected.
-
-All these devices are always connected. And with the number of
-alternatives to give you access to the content you seek, users
-tend to not stick around when problems arise. Users today want
-their applications to be always available and if it's having
-too many issues they just move on.
-
-Despite this, when developers choose a product to use for building
-web applications, their only concern seems to be "Is it fast?",
-and they look around for synthetic benchmarks showing which one
-is the fastest at sending "Hello world" with only a handful
-concurrent connections. Web benchmarks haven't been representative
-of reality in a long time, and are drifting further away as
-time goes on.
-
-What developers should really ask themselves is "Can I service
-all my users with no interruption?" and they'd find that they have
-two choices. They can either hope for the best, or they can use
-Erlang.
-
-Erlang is built for fault tolerance. When writing code in any other
-language, you have to check all the return values and act accordingly
-to avoid any unforeseen issues. If you're lucky, you won't miss
-anything important. When writing Erlang code, you can just check
-the success condition and ignore all errors. If an error happens,
-the Erlang process crashes and is then restarted by a special
-process called a supervisor.
-
-Erlang developers thus have no need to fear unhandled
-errors, and can focus on handling only the errors that should
-give some feedback to the user and let the system take care of
-the rest. This also has the advantage of allowing them to write
-a lot less code, and let them sleep at night.
-
-Erlang's fault tolerance oriented design is the first piece of
-what makes it the best choice for the omnipresent, always available
-Web.
-
-The second piece is Erlang's built-in distribution. Distribution
-is a key part of building a fault tolerant system, because it
-allows you to handle bigger failures, like a whole server going
-down, or even a data center entirely.
-
-Fault tolerance and distribution are important today, and will be
-vital in the future of the Web. Erlang is ready.
-
-=== Learn Erlang
-
-If you are new to Erlang, you may want to grab a book or
-two to get started. Those are my recommendations as the
-author of Cowboy.
-
-==== The Erlanger Playbook
-
-The Erlanger Playbook is an ebook I am currently writing,
-which covers a number of different topics from code to
-documentation to testing Erlang applications. It also has
-an Erlang section where it covers directly the building
-blocks and patterns, rather than details like the syntax.
-
-You can most likely read it as a complete beginner, but
-you will need a companion book to make the most of it.
-Buy it from the https://ninenines.eu[Nine Nines website].
-
-==== Programming Erlang
-
-This book is from one of the creator of Erlang, Joe
-Armstrong. It provides a very good explanation of what
-Erlang is and why it is so. It serves as a very good
-introduction to the language and platform.
-
-The book is http://pragprog.com/book/jaerlang2/programming-erlang[Programming Erlang],
-and it also features a chapter on Cowboy.
-
-==== Learn You Some Erlang for Great Good!
-
-http://learnyousomeerlang.com[LYSE] is a much more complete

-<h1 class="lined-header"><span>Erlang and the Web</span></h1>
-
-<p>Erlang is the ideal platform for writing Web applications. Its features are a perfect match for the requirements of modern Web applications.</p>
-<h2 id="_the_web_is_concurrent">The Web is concurrent</h2>
-<p>When you access a website there is little concurrency involved. A few connections are opened and requests are sent through these connections. Then the web page is displayed on your screen. Your browser will only open up to 4 or 8 connections to the server, depending on your settings. This isn&apos;t much.</p>
-<p>But think about it. You are not the only one accessing the server at the same time. There can be hundreds, if not thousands, if not millions of connections to the same server at the same time.</p>
-<p>Even today a lot of systems used in production haven&apos;t solved the C10K problem (ten thousand concurrent connections). And the ones who did are trying hard to get to the next step, C100K, and are pretty far from it.</p>
-<p>Erlang meanwhile has no problem handling millions of connections. At the time of writing there are application servers written in Erlang that can handle more than two million connections on a single server in a real production application, with spare memory and CPU!</p>
-<p>The Web is concurrent, and Erlang is a language designed for concurrency, so it is a perfect match.</p>
-<p>Of course, various platforms need to scale beyond a few million connections. This is where Erlang&apos;s built-in distribution mechanisms come in. If one server isn&apos;t enough, add more! Erlang allows you to use the same code for talking to local processes or to processes in other parts of your cluster, which means you can scale very quickly if the need arises.</p>
-<p>The Web has large userbases, and the Erlang platform was designed to work in a distributed setting, so it is a perfect match.</p>
-<p>Or is it? Surely you can find solutions to handle that many concurrent connections with your favorite language... But all these solutions will break down in the next few years. Why? Firstly because servers don&apos;t get any more powerful, they instead get a lot more cores and memory. This is only useful if your application can use them properly, and Erlang is light-years away from anything else in that area. Secondly, today your computer and your phone are online, tomorrow your watch, goggles, bike, car, fridge and tons of other devices will also connect to various applications on the Internet.</p>
-<p>Only Erlang is prepared to deal with what&apos;s coming.</p>
-<h2 id="_the_web_is_soft_real_time">The Web is soft real time</h2>
-<p>What does soft real time mean, you ask? It means we want the operations done as quickly as possible, and in the case of web applications, it means we want the data propagated fast.</p>
-<p>In comparison, hard real time has a similar meaning, but also has a hard time constraint, for example an operation needs to be done in under N milliseconds otherwise the system fails entirely.</p>
-<p>Users aren&apos;t that needy yet, they just want to get access to their content in a reasonable delay, and they want the actions they make to register at most a few seconds after they submitted them, otherwise they&apos;ll start worrying about whether it successfully went through.</p>
-<p>The Web is soft real time because taking longer to perform an operation would be seen as bad quality of service.</p>
-<p>Erlang is a soft real time system. It will always run processes fairly, a little at a time, switching to another process after a while and preventing a single process to steal resources from all others. This means that Erlang can guarantee stable low latency of operations.</p>
-<p>Erlang provides the guarantees that the soft real time Web requires.</p>
-<h2 id="_the_web_is_asynchronous">The Web is asynchronous</h2>
-<p>Long ago, the Web was synchronous because HTTP was synchronous. You fired a request, and then waited for a response. Not anymore. It all began when XmlHttpRequest started being used. It allowed the client to perform asynchronous calls to the server.</p>
-<p>Then Websocket appeared and allowed both the server and the client to send data to the other endpoint completely asynchronously. The data is contained within frames and no response is necessary.</p>
-<p>Erlang processes work the same. They send each other data contained within messages and then continue running without needing a response. They tend to spend most of their time inactive, waiting for a new message, and the Erlang VM happily activate them when one is received.</p>
-<p>It is therefore quite easy to imagine Erlang being good at receiving Websocket frames, which may come in at unpredictable times, pass the data to the responsible processes which are always ready waiting for new messages, and perform the operations required by only activating the required parts of the system.</p>
-<p>The more recent Web technologies, like Websocket of course, but also HTTP/2.0, are all fully asynchronous protocols. The concept of requests and responses is retained of course, but anything could be sent in between, by both the client or the browser, and the responses could also be received in a completely different order.</p>
-<p>Erlang is by nature asynchronous and really good at it thanks to the great engineering that has been done in the VM over the years. It&apos;s only natural that it&apos;s so good at dealing with the asynchronous Web.</p>
-<h2 id="_the_web_is_omnipresent">The Web is omnipresent</h2>
-<p>The Web has taken a very important part of our lives. We&apos;re connected at all times, when we&apos;re on our phone, using our computer, passing time using a tablet while in the bathroom... And this isn&apos;t going to slow down, every single device at home or on us will be connected.</p>
-<p>All these devices are always connected. And with the number of alternatives to give you access to the content you seek, users tend to not stick around when problems arise. Users today want their applications to be always available and if it&apos;s having too many issues they just move on.</p>
-<p>Despite this, when developers choose a product to use for building web applications, their only concern seems to be &quot;Is it fast?&quot;, and they look around for synthetic benchmarks showing which one is the fastest at sending &quot;Hello world&quot; with only a handful concurrent connections. Web benchmarks haven&apos;t been representative of reality in a long time, and are drifting further away as time goes on.</p>
-<p>What developers should really ask themselves is &quot;Can I service all my users with no interruption?&quot; and they&apos;d find that they have two choices. They can either hope for the best, or they can use Erlang.</p>
-<p>Erlang is built for fault tolerance. When writing code in any other language, you have to check all the return values and act accordingly to avoid any unforeseen issues. If you&apos;re lucky, you won&apos;t miss anything important. When writing Erlang code, you can just check the success condition and ignore all errors. If an error happens, the Erlang process crashes and is then restarted by a special process called a supervisor.</p>
-<p>Erlang developers thus have no need to fear unhandled errors, and can focus on handling only the errors that should give some feedback to the user and let the system take care of the rest. This also has the advantage of allowing them to write a lot less code, and let them sleep at night.</p>
-<p>Erlang&apos;s fault tolerance oriented design is the first piece of what makes it the best choice for the omnipresent, always available Web.</p>
-<p>The second piece is Erlang&apos;s built-in distribution. Distribution is a key part of building a fault tolerant system, because it allows you to handle bigger failures, like a whole server going down, or even a data center entirely.</p>
-<p>Fault tolerance and distribution are important today, and will be vital in the future of the Web. Erlang is ready.</p>
-<h2 id="_learn_erlang">Learn Erlang</h2>
-<p>If you are new to Erlang, you may want to grab a book or two to get started. Those are my recommendations as the author of Cowboy.</p>
-<h4 id="_the_erlanger_playbook">The Erlanger Playbook</h4>
-<p>The Erlanger Playbook is an ebook I am currently writing, which covers a number of different topics from code to documentation to testing Erlang applications. It also has an Erlang section where it covers directly the building blocks and patterns, rather than details like the syntax.</p>
-<p>You can most likely read it as a complete beginner, but you will need a companion book to make the most of it. Buy it from the <a href="https://ninenines.eu">Nine Nines website</a>.</p>
-<h4 id="_programming_erlang">Programming Erlang</h4>
-<p>This book is from one of the creator of Erlang, Joe Armstrong. It provides a very good explanation of what Erlang is and why it is so. It serves as a very good introduction to the language and platform.</p>
-<p>The book is <a href="http://pragprog.com/book/jaerlang2/programming-erlang">Programming Erlang</a>, and it also features a chapter on Cowboy.</p>
-<h4 id="_learn_you_some_erlang_for_great_good">Learn You Some Erlang for Great Good!</h4>
-<p><a href="http://learnyousomeerlang.com">LYSE</a> is a much more complete book covering many aspects of Erlang, while also providing stories and humor. Be warned: it&apos;s pretty verbose. It comes with a free online version and a more refined paper and ebook version.</p>

-[[flow_diagram]]
-== Flow diagram
-
-Cowboy is a lightweight HTTP server with support for HTTP/1.1,
-HTTP/2 and Websocket.
-
-It is built on top of Ranch. Please see the Ranch guide for more
-information about how the network connections are handled.
-
-=== Overview
-
-image::http_req_resp.png[HTTP request/response flowchart]
-
-As you can see on the diagram, the client
-begins by connecting to the server. This step is handled
-by a Ranch acceptor, which is a process dedicated to
-accepting new connections.
-
-After Ranch accepts a new connection, whether it is an
-HTTP/1.1 or HTTP/2 connection, Cowboy starts receiving
-requests and handling them.
-
-In HTTP/1.1 all requests come sequentially. In HTTP/2
-the requests may arrive and be processed concurrently.
-
-When a request comes in, Cowboy creates a stream, which
-is a set of request/response and all the events associated
-with them. The protocol code in Cowboy defers the handling
-of these streams to stream handler modules. When you
-configure Cowboy you may define one or more module that
-will receive all events associated with a stream, including
-the request, response, bodies, Erlang messages and more.
-
-By default Cowboy comes configured with a stream handler
-called `cowboy_stream_h`. This stream handler will create
-a new process for every request coming in, and then
-communicate with this process to read the body or send
-a response back. The request process executes middlewares
-which, by default, including the router and then the
-execution of handlers. Like stream handlers, middlewares
-may also be customized.
-
-A response may be sent at almost any point in this
-diagram. If the response must be sent before the stream
-is initialized (because an error occurred early, for
-example) then stream handlers receive a special event
-indicating this error.
-
-=== Protocol-specific headers
-
-Cowboy takes care of protocol-specific headers and prevents
-you from sending them manually. For HTTP/1.1 this includes
-the `transfer-encoding` and `connection` headers. For HTTP/2
-this includes the colon headers like `:status`.
-
-Cowboy will also remove protocol-specific headers from
-requests before passing them to stream handlers. Cowboy
-tries to hide the implementation details of all protocols
-as well as possible.
-
-=== Number of processes per connection
-
-By default, Cowboy will use one process per connection,
-plus one process per set of request/response (called a
-stream, internally).
-
-The reason it creates a new process for every request is due
-to the requirements of HTTP/2 where requests are executed
-concurrently and independently from the connection. The
-frames from the different requests end up interleaved on
-the single TCP connection.
-
-The request processes are never reused. There is therefore
-no need to perform any cleanup after the response has been
-sent. The process will terminate and Erlang/OTP will reclaim
-all memory at once.
-
-Cowboy ultimately does not require more than one process
-per connection. It is possible to interact with the connection
-directly from a stream handler, a low level interface to Cowboy.
-They are executed from within the connection process, and can
-handle the incoming requests and send responses. This is however
-not recommended in normal circumstances, as a stream handler
-taking too long to execute could have a negative impact on
-concurrent requests or the state of the connection itself.
-
-=== Date header
-
-Because querying for the current date and time can be expensive,
-Cowboy generates one 'Date' header value every second, shares it
-to all other processes, which then simply copy it in the response.
-This allows compliance with HTTP/1.1 with no actual performance loss.
-
-=== Binaries
-
-Cowboy makes extensive use of binaries.
-
-Binaries are more efficient than lists for representing
-strings because they take less memory space. Processing
-performance can vary depending on the operation. Binaries
-are known for generally getting a great boost if the code
-is compiled natively. Please see the HiPE documentation
-for more details.
-
-Binaries may end up being shared between processes. This
-can lead to some large memory usage when one process keeps
-the binary data around forever without freeing it. If you
-see some weird memory usage in your application, this might
-be the cause.

-<p>A response may be sent at almost any point in this diagram. If the response must be sent before the stream is initialized (because an error occurred early, for example) then stream handlers receive a special event indicating this error.</p>
-<h2 id="_protocol_specific_headers">Protocol-specific headers</h2>
-<p>Cowboy takes care of protocol-specific headers and prevents you from sending them manually. For HTTP/1.1 this includes the <code>transfer-encoding</code> and <code>connection</code> headers. For HTTP/2 this includes the colon headers like <code>:status</code>.</p>
-<p>Cowboy will also remove protocol-specific headers from requests before passing them to stream handlers. Cowboy tries to hide the implementation details of all protocols as well as possible.</p>
-<h2 id="_number_of_processes_per_connection">Number of processes per connection</h2>
-<p>By default, Cowboy will use one process per connection, plus one process per set of request/response (called a stream, internally).</p>
-<p>The reason it creates a new process for every request is due to the requirements of HTTP/2 where requests are executed concurrently and independently from the connection. The frames from the different requests end up interleaved on the single TCP connection.</p>
-<p>The request processes are never reused. There is therefore no need to perform any cleanup after the response has been sent. The process will terminate and Erlang/OTP will reclaim all memory at once.</p>
-<p>Cowboy ultimately does not require more than one process per connection. It is possible to interact with the connection directly from a stream handler, a low level interface to Cowboy. They are executed from within the connection process, and can handle the incoming requests and send responses. This is however not recommended in normal circumstances, as a stream handler taking too long to execute could have a negative impact on concurrent requests or the state of the connection itself.</p>
-<h2 id="_date_header">Date header</h2>
-<p>Because querying for the current date and time can be expensive, Cowboy generates one <em>Date</em> header value every second, shares it to all other processes, which then simply copy it in the response. This allows compliance with HTTP/1.1 with no actual performance loss.</p>
-<h2 id="_binaries">Binaries</h2>
-<p>Cowboy makes extensive use of binaries.</p>
-<p>Binaries are more efficient than lists for representing strings because they take less memory space. Processing performance can vary depending on the operation. Binaries are known for generally getting a great boost if the code is compiled natively. Please see the HiPE documentation for more details.</p>
-<p>Binaries may end up being shared between processes. This can lead to some large memory usage when one process keeps the binary data around forever without freeing it. If you see some weird memory usage in your application, this might be the cause.</p>

-[[getting_started]]
-== Getting started
-
-Erlang is more than a language, it is also an operating system
-for your applications. Erlang developers rarely write standalone
-modules, they write libraries or applications, and then bundle
-those into what is called a release. A release contains the
-Erlang VM plus all applications required to run the node, so
-it can be pushed to production directly.
-
-This chapter walks you through all the steps of setting up
-Cowboy, writing your first application and generating your first
-release. At the end of this chapter you should know everything
-you need to push your first Cowboy application to production.
-
-=== Prerequisites
-
-We are going to use the https://github.com/ninenines/erlang.mk[Erlang.mk]
-build system. If you are using Windows, please check the
-http://erlang.mk/guide/installation.html[Installation instructions]
-to get your environment setup before you continue.
-
-=== Bootstrap
-
-First, let's create the directory for our application.
-
-[source,bash]
-$ mkdir hello_erlang
-$ cd hello_erlang
-
-Then we need to download Erlang.mk. Either use the following
-command or download it manually.
-
-[source,bash]
-$ wget https://erlang.mk/erlang.mk
-
-We can now bootstrap our application. Since we are going to generate
-a release, we will also bootstrap it at the same time.
-
-[source,bash]
-$ make -f erlang.mk bootstrap bootstrap-rel
-
-This creates a Makefile, a base application, and the release files
-necessary for creating the release. We can already build and start
-this release.
-
-[source,bash]
-----
-$ make run
-...
-([email protected])1>
-----
-
-Entering the command `i().` will show the running processes, including
-one called `hello_erlang_sup`. This is the supervisor for our
-application.
-
-The release currently does nothing. In the rest of this chapter we
-will add Cowboy as a dependency and write a simple "Hello world!"
-handler.
-
-=== Cowboy setup
-
-We will modify the 'Makefile' to tell the build system it needs to
-fetch and compile Cowboy:
-
-[source,makefile]
-----
-PROJECT = hello_erlang
-
-DEPS = cowboy
-dep_cowboy_commit = master
-
-DEP_PLUGINS = cowboy
-
-include erlang.mk
-----
-
-We also tell the build system to load the plugins Cowboy provides.
-These include predefined templates that we will use soon.
-
-If you do `make run` now, Cowboy will be included in the release
-and started automatically. This is not enough however, as Cowboy
-doesn't do anything by default. We still need to tell Cowboy to
-listen for connections.
-
-=== Listening for connections
-
-First we define the routes that Cowboy will use to map requests
-to handler modules, and then we start the listener. This is best
-done at application startup.
-
-Open the 'src/hello_erlang_app.erl' file and add the necessary
-code to the `start/2` function to make it look like this:
-
-[source,erlang]
-----
-start(_Type, _Args) ->
-    Dispatch = cowboy_router:compile([
-        {'_', [{"/", hello_handler, []}]}
-    ]),
-    {ok, _} = cowboy:start_clear(my_http_listener,
-        [{port, 8080}],
-        #{env => #{dispatch => Dispatch}}
-    ),
-    hello_erlang_sup:start_link().
-----
-
-Routes are explained in details in the xref:routing[Routing]
-chapter. For this tutorial we map the path `/` to the handler
-module `hello_handler`. This module doesn't exist yet.
-
-Build and start the release, then open http://localhost:8080
-in your browser. You will get a 500 error because the module is missing.
-Any other URL, like http://localhost:8080/test, will result in a
-404 error.
-
-=== Handling requests
-
-Cowboy features different kinds of handlers, including REST
-and Websocket handlers. For this tutorial we will use a plain
-HTTP handler.
-
-Generate a handler from a template:
-
-[source,bash]
-$ make new t=cowboy.http n=hello_handler
-
-Then, open the 'src/hello_handler.erl' file and modify
-the `init/2` function like this to send a reply.
-
-[source,erlang]
-----
-init(Req0, State) ->
-    Req = cowboy_req:reply(200,
-        #{<<"content-type">> => <<"text/plain">>},
-        <<"Hello Erlang!">>,
-        Req0),
-    {ok, Req, State}.
-----
-
-What the above code does is send a 200 OK reply, with the
-Content-type header set to `text/plain` and the response
-body set to `Hello Erlang!`.
-
-If you run the release and open http://localhost:8080
-in your browser, you should get a nice `Hello Erlang!` displayed!

-[[handlers]]
-== Handlers
-
-Handlers are Erlang modules that handle HTTP requests.
-
-=== Plain HTTP handlers
-
-The most basic handler in Cowboy implements the mandatory
-`init/2` callback, manipulates the request, optionally
-sends a response and then returns.
-
-This callback receives the xref:req[Req object] and the initial
-state defined in the xref:routing[router configuration].
-
-A handler that does nothing would look like this:
-
-[source,erlang]
-----
-init(Req, State) ->
-    {ok, Req, State}.
-----
-
-Despite sending no reply, a `204 No Content` response will be
-sent to the client, as Cowboy makes sure that a response is
-sent for every request.
-
-We need to use the Req object to reply.
-
-[source,erlang]
-----
-init(Req0, State) ->
-    Req = cowboy_req:reply(200, #{
-        <<"content-type">> => <<"text/plain">>
-    }, <<"Hello World!">>, Req0),
-    {ok, Req, State}.
-----
-
-Cowboy will immediately send a response when `cowboy:reply/4`
-is called.
-
-We then return a 3-tuple. `ok` means that the handler ran
-successfully. We also give the modified Req back to Cowboy.
-
-The last value of the tuple is a state that will be used
-in every subsequent callbacks to this handler. Plain HTTP
-handlers only have one additional callback, the optional
-and rarely used `terminate/3`.
-
-=== Other handlers
-
-The `init/2` callback can also be used to inform Cowboy
-that this is a different kind of handler and that Cowboy
-should switch to it. To do this you simply need to return
-the module name of the handler type you want to switch to.
-
-Cowboy comes with three handler types you can switch to:
-xref:rest_handlers[cowboy_rest], xref:ws_handlers[cowboy_websocket]
-and xref:loop_handlers[cowboy_loop]. In addition to those you
-can define your own handler types.
-
-Switching is simple. Instead of returning `ok`, you simply
-return the name of the handler type you want to use. The
-following snippet switches to a Websocket handler:
-
-[source,erlang]
-----
-init(Req, State) ->
-    {cowboy_websocket, Req, State}.
-----
-
-=== Cleaning up
-
-All handler types provide the optional `terminate/3` callback.
-
-[source,erlang]
-----
-terminate(_Reason, _Req, _State) ->
-    ok.
-----
-
-This callback is strictly reserved for any required cleanup.
-You cannot send a response from this function. There is no
-other return value.
-
-This callback is optional because it is rarely necessary.
-Cleanup should be done in separate processes directly (by
-monitoring the handler process to detect when it exits).
-
-Cowboy does not reuse processes for different requests. The
-process will terminate soon after this call returns.

-== Introduction
-
-Cowboy is a small, fast and modern HTTP server for Erlang/OTP.
-
-Cowboy aims to provide a complete xref:modern_web[modern Web stack].
-This includes HTTP/1.1, HTTP/2, Websocket, Server-Sent Events and
-Webmachine-based REST.
-
-Cowboy comes with functions for introspection and tracing, enabling
-developers to know precisely what is happening at any time. Its modular
-design also easily enable developers to add instrumentation.
-
-Cowboy is a high quality project. It has a small code base, is very
-efficient (both in latency and memory use) and can easily be embedded
-in another application.
-
-Cowboy is clean Erlang code. It includes hundreds of tests and its code
-is fully compliant with the Dialyzer. It is also well documented and
-features a Function Reference, a User Guide and numerous Tutorials.
-
-=== Prerequisites
-
-Beginner Erlang knowledge is recommended for reading this guide.
-
-Knowledge of the HTTP protocol is recommended but not required, as it
-will be detailed throughout the guide.
-
-=== Supported platforms
-
-Cowboy is tested and supported on Linux, FreeBSD, Windows and OSX.
-
-Cowboy has been reported to work on other platforms, but we make no
-guarantee that the experience will be safe and smooth. You are advised
-to perform the necessary testing and security audits prior to deploying
-on other platforms.
-
-Cowboy is developed for Erlang/OTP 19.0 and newer.
-
-=== License
-
-Cowboy uses the ISC License.

-=== Conventions
-
-In the HTTP protocol, the method name is case sensitive. All standard
-method names are uppercase.
-
-Header names are case insensitive. When using HTTP/1.1, Cowboy converts
-all the request header names to lowercase. HTTP/2 requires clients to
-send them as lowercase. Any other header name is expected to be provided
-lowercased, including when querying information about the request or
-when sending responses.
-
-The same applies to any other case insensitive value.

-[[listeners]]
-== Listeners
-
-A listener is a set of processes that listens on a port for
-new connections. Incoming connections get handled by Cowboy.
-Depending on the connection handshake, one or another protocol
-may be used.
-
-This chapter is specific to Cowboy. Please refer to the
-https://ninenines.eu/docs/en/ranch/1.3/guide/listeners/[Ranch User Guide]
-for more information about listeners.
-
-Cowboy provides two types of listeners: one listening for
-clear TCP connections, and one listening for secure TLS
-connections. Both of them support the HTTP/1.1 and HTTP/2
-protocols.
-
-=== Clear TCP listener
-
-The clear TCP listener will accept connections on the
-given port. A typical HTTP server would listen on port 80.
-Port 80 requires special permissions on most platforms
-however so a common alternative is port 8080.
-
-The following snippet starts listening for connections
-on port 8080:
-
-[source,erlang]
-----
-start(_Type, _Args) ->
-    Dispatch = cowboy_router:compile([
-        {'_', [{"/", hello_handler, []}]}
-    ]),
-    {ok, _} = cowboy:start_clear(my_http_listener,
-        [{port, 8080}],
-        #{env => #{dispatch => Dispatch}}
-    ),
-    hello_erlang_sup:start_link().
-----
-
-The xref:getting_started[Getting Started] chapter uses a
-clear TCP listener.
-
-Clients connecting to Cowboy on the clear listener port are
-expected to use either HTTP/1.1 or HTTP/2.
-
-Cowboy supports both methods of initiating a clear
-HTTP/2 connection: through the Upgrade mechanism
-(https://tools.ietf.org/html/rfc7540#section-3.2[RFC 7540 3.2])
-or by sending the preface directly
-(https://tools.ietf.org/html/rfc7540#section-3.4[RFC 7540 3.4]).
-
-Compatibility with HTTP/1.0 is provided by Cowboy's HTTP/1.1
-implementation.
-
-=== Secure TLS listener
-
-The secure TLS listener will accept connections on the
-given port. A typical HTTPS server would listen on port 443.
-Port 443 requires special permissions on most platforms
-however so a common alternative is port 8443.
-
-// @todo Make a complete list of restrictions.
-
-The function provided by Cowboy will ensure that the TLS
-options given are following the HTTP/2 RFC with regards
-to security. For example some TLS extensions or ciphers
-may be disabled. This also applies to HTTP/1.1 connections
-on this listener. If this is not desirable, Ranch can be
-used directly to setup a custom listener.
-
-[source,erlang]
-----
-start(_Type, _Args) ->
-    Dispatch = cowboy_router:compile([
-        {'_', [{"/", hello_handler, []}]}
-    ]),
-    {ok, _} = cowboy:start_tls(my_http_listener,
-        [
-            {port, 8443},
-            {certfile, "/path/to/certfile"},
-            {keyfile, "/path/to/keyfile"}
-        ],
-        #{env => #{dispatch => Dispatch}}
-    ),
-    hello_erlang_sup:start_link().
-----
-
-Clients connecting to Cowboy on the secure listener are
-expected to use the ALPN TLS extension to indicate what
-protocols they understand. Cowboy always prefers HTTP/2
-over HTTP/1.1 when both are supported. When neither are
-supported by the client, or when the ALPN extension was
-missing, Cowboy expects HTTP/1.1 to be used.
-
-Cowboy also advertises HTTP/2 support through the older
-NPN TLS extension for compatibility. Note however that
-this support will likely not be enabled by default when
-Cowboy 2.0 gets released.
-
-Compatibility with HTTP/1.0 is provided by Cowboy's HTTP/1.1
-implementation.
-
-=== Protocol configuration
-
-The HTTP/1.1 and HTTP/2 protocols share the same semantics;
-only their framing differs. The first is a text protocol and
-the second a binary protocol.
-
-Cowboy doesn't separate the configuration for HTTP/1.1 and
-HTTP/2. Everything goes into the same map. Many options are
-shared.
-
-// @todo Describe good to know options for both protocols?
-// Maybe do that in separate chapters?

-[[loop_handlers]]
-== Loop handlers
-
-Loop handlers are a special kind of HTTP handlers used when the
-response can not be sent right away. The handler enters instead
-a receive loop waiting for the right message before it can send
-a response.
-
-Loop handlers are used for requests where a response might not
-be immediately available, but where you would like to keep the
-connection open for a while in case the response arrives. The
-most known example of such practice is known as long polling.
-
-Loop handlers can also be used for requests where a response is
-partially available and you need to stream the response body
-while the connection is open. The most known example of such
-practice is server-sent events.
-
-While the same can be accomplished using plain HTTP handlers,
-it is recommended to use loop handlers because they are well-tested
-and allow using built-in features like hibernation and timeouts.
-
-Loop handlers essentially wait for one or more Erlang messages
-and feed these messages to the `info/3` callback. It also features
-the `init/2` and `terminate/3` callbacks which work the same as
-for plain HTTP handlers.
-
-=== Initialization
-
-The `init/2` function must return a `cowboy_loop` tuple to enable
-loop handler behavior. This tuple may optionally contain
-a timeout value and/or the atom `hibernate` to make the
-process enter hibernation until a message is received.
-
-This snippet enables the loop handler:
-
-[source,erlang]
-----
-init(Req, State) ->
-    {cowboy_loop, Req, State}.
-----
-
-This also makes the process hibernate:
-
-[source,erlang]
-----
-init(Req, State) ->
-    {cowboy_loop, Req, State, hibernate}.
-----
-
-=== Receive loop
-
-Once initialized, Cowboy will wait for messages to arrive
-in the process' mailbox. When a message arrives, Cowboy
-calls the `info/3` function with the message, the Req object
-and the handler's state.
-
-The following snippet sends a reply when it receives a
-`reply` message from another process, or waits for another
-message otherwise.
-
-[source,erlang]
-----
-info({reply, Body}, Req, State) ->
-    cowboy_req:reply(200, #{}, Body, Req),
-    {stop, Req, State};
-info(_Msg, Req, State) ->
-    {ok, Req, State, hibernate}.
-----
-
-Do note that the `reply` tuple here may be any message
-and is simply an example.
-
-This callback may perform any necessary operation including
-sending all or parts of a reply, and will subsequently
-return a tuple indicating if more messages are to be expected.
-
-The callback may also choose to do nothing at all and just
-skip the message received.
-
-If a reply is sent, then the `stop` tuple should be returned.
-This will instruct Cowboy to end the request.
-
-Otherwise an `ok` tuple should be returned.
-
-=== Streaming loop
-
-Another common case well suited for loop handlers is
-streaming data received in the form of Erlang messages.
-This can be done by initiating a chunked reply in the
-`init/2` callback and then using `cowboy_req:chunk/2`
-every time a message is received.
-
-The following snippet does exactly that. As you can see
-a chunk is sent every time an `event` message is received,
-and the loop is stopped by sending an `eof` message.
-
-[source,erlang]
-----
-init(Req, State) ->
-    Req2 = cowboy_req:stream_reply(200, Req),
-    {cowboy_loop, Req2, State}.
-
-info(eof, Req, State) ->
-    {stop, Req, State};
-info({event, Data}, Req, State) ->
-    cowboy_req:stream_body(Data, nofin, Req),
-    {ok, Req, State};
-info(_Msg, Req, State) ->
-    {ok, Req, State}.
-----
-
-=== Cleaning up
-
-It is recommended that you set the connection header to
-`close` when replying, as this process may be reused for
-a subsequent request.
-
-Please refer to the xref:handlers[Handlers chapter]
-for general instructions about cleaning up.
-
-=== Hibernate
-
-To save memory, you may hibernate the process in between
-messages received. This is done by returning the atom
-`hibernate` as part of the `loop` tuple callbacks normally
-return. Just add the atom at the end and Cowboy will hibernate
-accordingly.

-<h2 id="_cleaning_up">Cleaning up</h2>
-<p>It is recommended that you set the connection header to <code>close</code> when replying, as this process may be reused for a subsequent request.</p>
-<p>Please refer to the <a href="../handlers">Handlers chapter</a> for general instructions about cleaning up.</p>
-<h2 id="_hibernate">Hibernate</h2>
-<p>To save memory, you may hibernate the process in between messages received. This is done by returning the atom <code>hibernate</code> as part of the <code>loop</code> tuple callbacks normally return. Just add the atom at the end and Cowboy will hibernate accordingly.</p>

-[[middlewares]]
-== Middlewares
-
-Cowboy delegates the request processing to middleware components.
-By default, two middlewares are defined, for the routing and handling
-of the request, as is detailed in most of this guide.
-
-Middlewares give you complete control over how requests are to be
-processed. You can add your own middlewares to the mix or completely
-change the chain of middlewares as needed.
-
-Cowboy will execute all middlewares in the given order, unless one
-of them decides to stop processing.
-
-=== Usage
-
-Middlewares only need to implement a single callback: `execute/2`.
-It is defined in the `cowboy_middleware` behavior.
-
-This callback has two arguments. The first is the `Req` object.
-The second is the environment.
-
-Middlewares can return one of three different values:
-
-* `{ok, Req, Env}` to continue the request processing
-* `{suspend, Module, Function, Args}` to hibernate
-* `{stop, Req}` to stop processing and move on to the next request
-
-Of note is that when hibernating, processing will resume on the given
-MFA, discarding all previous stacktrace. Make sure you keep the `Req`
-and `Env` in the arguments of this MFA for later use.
-
-If an error happens during middleware processing, Cowboy will not try
-to send an error back to the socket, the process will just crash. It
-is up to the middleware to make sure that a reply is sent if something
-goes wrong.
-
-=== Configuration
-
-The middleware environment is defined as the `env` protocol option.
-In the previous chapters we saw it briefly when we needed to pass
-the routing information. It is a list of tuples with the first
-element being an atom and the second any Erlang term.
-
-Two values in the environment are reserved:
-
-* `listener` contains the name of the listener
-* `result` contains the result of the processing
-
-The `listener` value is always defined. The `result` value can be
-set by any middleware. If set to anything other than `ok`, Cowboy
-will not process any subsequent requests on this connection.
-
-The middlewares that come with Cowboy may define or require other
-environment values to perform.
-
-You can update the environment by calling the `cowboy:set_env/3`
-convenience function, adding or replacing a value in the environment.
-
-=== Routing middleware
-
-The routing middleware requires the `dispatch` value. If routing
-succeeds, it will put the handler name and options in the `handler`
-and `handler_opts` values of the environment, respectively.
-
-=== Handler middleware
-
-The handler middleware requires the `handler` and `handler_opts`
-values. It puts the result of the request handling into `result`.

-[appendix]
-== Migrating from Cowboy 1.0 to 2.0
-
-A lot has changed between Cowboy 1.0 and 2.0. The `cowboy_req`
-interface in particular has seen a massive revamp. Hooks are
-gone, their functionality can now be achieved via stream
-handlers.
-
-The documentation has seen great work, in particular the
-manual. Each module and each function now has its own dedicated
-manual page with full details and examples.
-
-=== Compatibility
-
-Compatibility with Erlang/OTP R16, 17 and 18 has been dropped.
-Erlang/OTP 19.0 or above is required. It is non-trivial to
-make Cowboy 2.0 work with older Erlang/OTP versions.
-
-Cowboy 2.0 is not compatible with Cowlib versions older than
-2.0. It should be compatible with Ranch 1.0 or above, however
-it has not been tested with Ranch versions older than 1.4.
-
-Cowboy 2.0 is tested on Arch Linux, Ubuntu, FreeBSD, Windows
-and OSX. It is tested with every point release (latest patch
-release) and also with HiPE on the most recent release.
-
-Cowboy 2.0 now comes with Erlang.mk templates.
-
-=== Features added
-
-* The HTTP/2 protocol is now supported.
-
-* Cowboy no longer uses only one process per connection.
-  It now uses one process per connection plus one process
-  per request by default. This is necessary for HTTP/2.
-  There might be a slight drop in performance for HTTP/1.1
-  connections due to this change.
-
-* Cowboy internals have largely been reworked in order to
-  support HTTP/2. This opened the way to stream handlers,
-  which are a chain of modules that are called whenever
-  something happens relating to a request/response.
-
-* The `cowboy_stream_h` stream handler has been added.
-  It provides most of Cowboy's default behavior.
-
-* The `cowboy_compress_h` stream handler has been added.
-  It compresses responses when possible. It's worth noting
-  that it compresses in more cases than Cowboy 1.0 ever did.
-
-* Because of the many changes in the internals of Cowboy,
-  many options have been added or modified. Of note is that
-  the Websocket options are now given per handler rather
-  than for the entire listener.
-
-* Websocket permessage-deflate compression is now supported
-  via the `compress` option.
-
-* Static file handlers will now correctly find files found
-  in '.ez' archives.
-
-* Constraints have been generalized and are now used not only
-  in the router but also in some `cowboy_req` functions. Their
-  interface has also been modified to allow for reverse
-  operations and formatting of errors.
-
-=== Features removed
-
-* SPDY support has been removed. Use HTTP/2 instead.
-
-* Hooks have been removed. Use xref:streams[stream handlers] instead.
-
-* The undocumented `waiting_stream` hack has been removed.
-  It allowed disabling chunked transfer-encoding for HTTP/1.1.
-  It has no equivalent in Cowboy 2.0. Open a ticket if necessary.
-
-* Sub protocols still exist, but their interface has largely changed
-  and they are no longer documented for the time being.
-
-=== Changed behaviors
-
-* The handler behaviors have been renamed and are now `cowboy_handler`,
-  `cowboy_loop`, `cowboy_rest` and `cowboy_websocket`.
-
-* Plain HTTP, loop, REST and Websocket handlers have had their
-  init and terminate callbacks unified. They now all use the
-  `init/2` and `terminate/3` callbacks. The latter is now optional.
-  The terminate reason has now been documented for all handlers.
-
-* The tuple returned to switch to a different handler type has
-  changed. It now takes the form `{Module, Req, State}` or
-  `{Module, Req, State, Opts}`, where `Opts` is a map of options
-  to configure the handler. The timeout and hibernate options
-  must now be specified using this map, where applicable.
-
-* All behaviors that used to accept `halt` or `shutdown` tuples
-  as a return value no longer do so. The return value is now
-  a `stop` tuple, consistent across Cowboy.
-
-* Middlewares can no longer return an `error` tuple. They have
-  to send the response and return a `stop` tuple instead.
-
-* The `known_content_type` REST handler callback has been removed
-  as it was found unnecessary.
-
-* Websocket handlers have both the normal `init/2` and
-  an optional `websocket_init/1` function. The reason for
-  that exception is that the `websocket_*` callbacks execute
-  in a separate process from the `init/2` callback, and it
-  was therefore not obvious how timers or monitors should
-  be setup properly. They are effectively initializing the
-  handler before and after the HTTP/1.1 upgrade.
-
-* Websocket handlers can now send frames directly from
-  `websocket_init/1`. The frames will be sent immediately
-  after the handshake.
-
-* Websocket handler callbacks no longer receive the Req
-  argument. The `init/2` callback still receives it and
-  can be used to extract relevant information. The `terminate/3`
-  callback, if implemented, may still receive the Req
-  (see next bullet point).
-
-* Websocket handlers have a new `req_filter` option that
-  can be used to customize how much information should be
-  discarded from the Req object after the handshake. Note
-  that the Req object is only available in `terminate/3`
-  past that point.
-
-* Websocket handlers have their timeout default changed
-  from infinity to 60 seconds.
-
-=== New functions
-
-* The `cowboy_req:scheme/1` function has been added.
-
-* The `cowboy_req:uri/1,2` function has been added, replacing the
-  less powerful functions `cowboy_req:url/1` and `cowboy_req:host_url/1`.
-
-* The functions `cowboy_req:match_qs/2` and `cowboy_req:match_cookies/2`
-  allow matching query string and cookies against constraints.
-
-* The function `cowboy_req:set_resp_cookie/3` has been added to
-  complement `cowboy_req:set_resp_cookie/4`.
-
-* The functions `cowboy_req:resp_header/2,3` and `cowboy_req:resp_headers/1`
-  have been added. They can be used to retrieve response headers
-  that were previously set.
-
-* The function `cowboy_req:set_resp_headers/2` has been added. It
-  allows setting many response headers at once.
-
-* The functions `cowboy_req:push/3,4` can be used to push resources
-  for protocols that support it (by default only HTTP/2).
-
-=== Changed functions
-
-* The `cowboy:start_http/4` function was renamed to `cowboy:start_clear/3`.
-
-* The `cowboy:start_https/4` function was renamed to `cowboy:start_tls/3`.
-
-* Most, if not all, functions in the `cowboy_req` module have been modified.
-  Please consult the changelog of each individual functions. The changes
-  are mainly about simplifying and clarifying the interface. The Req is no
-  longer returned when not necessary, maps are used wherever possible,
-  and some functions have been renamed.
-
-* The position of the `Opts` argument for `cowboy_req:set_resp_cookie/4`
-  has changed to improve consistency. It is now the last argument.
-
-=== Removed functions
-
-* The functions `cowboy_req:url/1` and `cowboy_req:host_url/1` have been
-  removed in favor of the new function `cowboy_req:uri/1,2`.
-
-* The functions `cowboy_req:meta/2,3` and `cowboy_req:set_meta/3` have
-  been removed. The Req object is now a public map, therefore they became
-  unnecessary.
-
-* The functions `cowboy_req:set_resp_body_fun/2,3` have been removed.
-  For sending files, the function `cowboy_req:set_resp_body/2` can now
-  take a sendfile tuple.
-
-* Remove many undocumented functions from `cowboy_req`, including the
-  functions `cowboy_req:get/2` and `cowboy_req:set/3`.
-
-=== Other changes
-
-* The correct percent-decoding algorithm is now used for path elements
-  during routing. It will no longer decode `+` characters.
-
-* The router will now properly handle path segments `.` and `..`.
-
-* Routing behavior has changed for URIs containing latin1 characters.
-  They are no longer allowed. URIs are expected to be in UTF-8 once
-  they are percent-decoded.
-
-* Etag comparison in REST handlers has been fixed. Some requests may
-  now fail when they succeeded in the past.
-
-* The `If-*-Since` headers are now ignored in REST handlers if
-  the corresponding `If*-Match` header exist. The former is
-  largely a backward compatible header and this shouldn't create
-  any issue. The new behavior follows the current RFCs more closely.
-
-* The static file handler has been improved to handle more special
-  characters on systems that accept them.

-<h1 class="lined-header"><span>Migrating from Cowboy 1.0 to 2.0</span></h1>
-
-<p>A lot has changed between Cowboy 1.0 and 2.0. The <code>cowboy_req</code> interface in particular has seen a massive revamp. Hooks are gone, their functionality can now be achieved via stream handlers.</p>
-<p>The documentation has seen great work, in particular the manual. Each module and each function now has its own dedicated manual page with full details and examples.</p>
-<h2 id="_compatibility">Compatibility</h2>
-<p>Compatibility with Erlang/OTP R16, 17 and 18 has been dropped. Erlang/OTP 19.0 or above is required. It is non-trivial to make Cowboy 2.0 work with older Erlang/OTP versions.</p>
-<p>Cowboy 2.0 is not compatible with Cowlib versions older than 2.0. It should be compatible with Ranch 1.0 or above, however it has not been tested with Ranch versions older than 1.4.</p>
-<p>Cowboy 2.0 is tested on Arch Linux, Ubuntu, FreeBSD, Windows and OSX. It is tested with every point release (latest patch release) and also with HiPE on the most recent release.</p>
-<p>Cowboy 2.0 now comes with Erlang.mk templates.</p>
-<h2 id="_features_added">Features added</h2>
-<ul><li>The HTTP/2 protocol is now supported.
-</li>
-<li>Cowboy no longer uses only one process per connection. It now uses one process per connection plus one process per request by default. This is necessary for HTTP/2. There might be a slight drop in performance for HTTP/1.1 connections due to this change.
-</li>
-<li>Cowboy internals have largely been reworked in order to support HTTP/2. This opened the way to stream handlers, which are a chain of modules that are called whenever something happens relating to a request/response.
-</li>
-<li>The <code>cowboy_stream_h</code> stream handler has been added. It provides most of Cowboy&apos;s default behavior.
-</li>
-<li>The <code>cowboy_compress_h</code> stream handler has been added. It compresses responses when possible. It&apos;s worth noting that it compresses in more cases than Cowboy 1.0 ever did.
-</li>
-<li>Because of the many changes in the internals of Cowboy, many options have been added or modified. Of note is that the Websocket options are now given per handler rather than for the entire listener.
-</li>
-<li>Websocket permessage-deflate compression is now supported via the <code>compress</code> option.
-</li>
-<li>Static file handlers will now correctly find files found in <em>.ez</em> archives.
-</li>
-<li>Constraints have been generalized and are now used not only in the router but also in some <code>cowboy_req</code> functions. Their interface has also been modified to allow for reverse operations and formatting of errors.
-</li>
-</ul>
-<h2 id="_features_removed">Features removed</h2>
-<ul><li>SPDY support has been removed. Use HTTP/2 instead.
-</li>
-<li>Hooks have been removed. Use <a href="../streams">stream handlers</a> instead.
-</li>
-<li>The undocumented <code>waiting_stream</code> hack has been removed. It allowed disabling chunked transfer-encoding for HTTP/1.1. It has no equivalent in Cowboy 2.0. Open a ticket if necessary.
-</li>
-<li>Sub protocols still exist, but their interface has largely changed and they are no longer documented for the time being.
-</li>
-</ul>
-<h2 id="_changed_behaviors">Changed behaviors</h2>
-<ul><li>The handler behaviors have been renamed and are now <code>cowboy_handler</code>, <code>cowboy_loop</code>, <code>cowboy_rest</code> and <code>cowboy_websocket</code>.
-</li>
-<li>Plain HTTP, loop, REST and Websocket handlers have had their init and terminate callbacks unified. They now all use the <code>init/2</code> and <code>terminate/3</code> callbacks. The latter is now optional. The terminate reason has now been documented for all handlers.
-</li>
-<li>The tuple returned to switch to a different handler type has changed. It now takes the form <code>{Module, Req, State}</code> or <code>{Module, Req, State, Opts}</code>, where <code>Opts</code> is a map of options to configure the handler. The timeout and hibernate options must now be specified using this map, where applicable.
-</li>
-<li>All behaviors that used to accept <code>halt</code> or <code>shutdown</code> tuples as a return value no longer do so. The return value is now a <code>stop</code> tuple, consistent across Cowboy.
-</li>
-<li>Middlewares can no longer return an <code>error</code> tuple. They have to send the response and return a <code>stop</code> tuple instead.
-</li>
-<li>The <code>known_content_type</code> REST handler callback has been removed as it was found unnecessary.
-</li>
-<li>Websocket handlers have both the normal <code>init/2</code> and an optional <code>websocket_init/1</code> function. The reason for that exception is that the <code>websocket_*</code> callbacks execute in a separate process from the <code>init/2</code> callback, and it was therefore not obvious how timers or monitors should be setup properly. They are effectively initializing the handler before and after the HTTP/1.1 upgrade.
-</li>
-<li>Websocket handlers can now send frames directly from <code>websocket_init/1</code>. The frames will be sent immediately after the handshake.
-</li>
-<li>Websocket handler callbacks no longer receive the Req argument. The <code>init/2</code> callback still receives it and can be used to extract relevant information. The <code>terminate/3</code> callback, if implemented, may still receive the Req (see next bullet point).
-</li>
-<li>Websocket handlers have a new <code>req_filter</code> option that can be used to customize how much information should be discarded from the Req object after the handshake. Note that the Req object is only available in <code>terminate/3</code> past that point.
-</li>
-<li>Websocket handlers have their timeout default changed from infinity to 60 seconds.
-</li>

-[[modern_web]]
-== The modern Web
-
-Cowboy is a server for the modern Web. This chapter explains
-what it means and details all the standards involved.
-
-Cowboy supports all the standards listed in this document.
-
-=== HTTP/2
-
-HTTP/2 is the most efficient protocol for consuming Web
-services. It enables clients to keep a connection open
-for long periods of time; to send requests concurrently;
-to reduce the size of requests through HTTP headers
-compression; and more. The protocol is binary, greatly
-reducing the resources needed to parse it.
-
-HTTP/2 also enables the server to push messages to the
-client. This can be used for various purposes, including
-the sending of related resources before the client requests
-them, in an effort to reduce latency. This can also be used
-to enable bidirectional communication.
-
-Cowboy provides transparent support for HTTP/2. Clients
-that know it can use it; others fall back to HTTP/1.1
-automatically.
-
-HTTP/2 is compatible with the HTTP/1.1 semantics.
-
-HTTP/2 is defined by RFC 7540 and RFC 7541.
-
-=== HTTP/1.1
-
-HTTP/1.1 is the previous version of the HTTP protocol.
-The protocol itself is text-based and suffers from numerous
-issues and limitations. In particular it is not possible
-to execute requests concurrently (though pipelining is
-sometimes possible), and it's also sometimes difficult
-to detect that a client disconnected.
-
-HTTP/1.1 does provide very good semantics for interacting
-with Web services. It defines the standard methods, headers
-and status codes used by HTTP/1.1 and HTTP/2 clients and
-servers.
-
-HTTP/1.1 also defines compatibility with an older version
-of the protocol, HTTP/1.0, which was never really standardized
-across implementations.
-
-The core of HTTP/1.1 is defined by RFC 7230, RFC 7231,
-RFC 7232, RFC 7233, RFC 7234 and RFC 7235. Numerous RFCs
-and other specifications exist defining additional HTTP
-methods, status codes, headers or semantics.
-
-=== Websocket
-
-xref:ws_protocol[Websocket] is a protocol built on top of HTTP/1.1
-that provides a two-ways communication channel between the client and
-the server. Communication is asynchronous and can occur concurrently.
-
-It consists of a Javascript object allowing setting up a
-Websocket connection to the server, and a binary based
-protocol for sending data to the server or the client.
-
-Websocket connections can transfer either UTF-8 encoded text
-data or binary data. The protocol also includes support for
-implementing a ping/pong mechanism, allowing the server and
-the client to have more confidence that the connection is still
-alive.
-
-A Websocket connection can be used to transfer any kind of data,
-small or big, text or binary. Because of this Websocket is
-sometimes used for communication between systems.
-
-Websocket messages have no semantics on their own. Websocket
-is closer to TCP in that aspect, and requires you to design
-and implement your own protocol on top of it; or adapt an
-existing protocol to Websocket.
-
-Cowboy provides an interface known as xref:ws_handlers[Websocket handlers]
-that gives complete control over a Websocket connection.
-
-The Websocket protocol is defined by RFC 6455.
-
-=== Long-lived requests
-
-Cowboy provides an interface that can be used to support
-long-polling or to stream large amounts of data reliably,
-including using Server-Sent Events.
-
-Long-polling is a mechanism in which the client performs
-a request which may not be immediately answered by the
-server. It allows clients to request resources that may
-not currently exist, but are expected to be created soon,
-and which will be returned as soon as they are.
-
-Long-polling is essentially a hack, but it is widely used
-to overcome limitations on older clients and servers.
-
-Server-Sent Events is a small protocol defined as a media
-type, `text/event-stream`, along with a new HTTP header,
-`Last-Event-ID`. It is defined in the EventSource W3C
-specification.
-
-Cowboy provides an interface known as xref:loop_handlers[loop handlers]
-that facilitates the implementation of long-polling or stream
-mechanisms. It works regardless of the underlying protocol.
-
-=== REST
-
-xref:rest_principles[REST, or REpresentational State Transfer],
-is a style of architecture for loosely connected distributed
-systems. It can easily be implemented on top of HTTP.
-
-REST is essentially a set of constraints to be followed.
-Many of these constraints are purely architectural and
-solved by simply using HTTP. Some constraints must be
-explicitly followed by the developer.

-<h1 class="lined-header"><span>The modern Web</span></h1>
-
-<p>Cowboy is a server for the modern Web. This chapter explains what it means and details all the standards involved.</p>
-<p>Cowboy supports all the standards listed in this document.</p>
-<h2 id="_http_2">HTTP/2</h2>
-<p>HTTP/2 is the most efficient protocol for consuming Web services. It enables clients to keep a connection open for long periods of time; to send requests concurrently; to reduce the size of requests through HTTP headers compression; and more. The protocol is binary, greatly reducing the resources needed to parse it.</p>
-<p>HTTP/2 also enables the server to push messages to the client. This can be used for various purposes, including the sending of related resources before the client requests them, in an effort to reduce latency. This can also be used to enable bidirectional communication.</p>
-<p>Cowboy provides transparent support for HTTP/2. Clients that know it can use it; others fall back to HTTP/1.1 automatically.</p>
-<p>HTTP/2 is compatible with the HTTP/1.1 semantics.</p>
-<p>HTTP/2 is defined by RFC 7540 and RFC 7541.</p>
-<h2 id="_http_1_1">HTTP/1.1</h2>
-<p>HTTP/1.1 is the previous version of the HTTP protocol. The protocol itself is text-based and suffers from numerous issues and limitations. In particular it is not possible to execute requests concurrently (though pipelining is sometimes possible), and it&apos;s also sometimes difficult to detect that a client disconnected.</p>
-<p>HTTP/1.1 does provide very good semantics for interacting with Web services. It defines the standard methods, headers and status codes used by HTTP/1.1 and HTTP/2 clients and servers.</p>
-<p>HTTP/1.1 also defines compatibility with an older version of the protocol, HTTP/1.0, which was never really standardized across implementations.</p>
-<p>The core of HTTP/1.1 is defined by RFC 7230, RFC 7231, RFC 7232, RFC 7233, RFC 7234 and RFC 7235. Numerous RFCs and other specifications exist defining additional HTTP methods, status codes, headers or semantics.</p>
-<h2 id="_websocket">Websocket</h2>
-<p><a href="../ws_protocol">Websocket</a> is a protocol built on top of HTTP/1.1 that provides a two-ways communication channel between the client and the server. Communication is asynchronous and can occur concurrently.</p>
-<p>It consists of a Javascript object allowing setting up a Websocket connection to the server, and a binary based protocol for sending data to the server or the client.</p>
-<p>Websocket connections can transfer either UTF-8 encoded text data or binary data. The protocol also includes support for implementing a ping/pong mechanism, allowing the server and the client to have more confidence that the connection is still alive.</p>
-<p>A Websocket connection can be used to transfer any kind of data, small or big, text or binary. Because of this Websocket is sometimes used for communication between systems.</p>
-<p>Websocket messages have no semantics on their own. Websocket is closer to TCP in that aspect, and requires you to design and implement your own protocol on top of it; or adapt an existing protocol to Websocket.</p>
-<p>Cowboy provides an interface known as <a href="../ws_handlers">Websocket handlers</a> that gives complete control over a Websocket connection.</p>
-<p>The Websocket protocol is defined by RFC 6455.</p>
-<h2 id="_long_lived_requests">Long-lived requests</h2>
-<p>Cowboy provides an interface that can be used to support long-polling or to stream large amounts of data reliably, including using Server-Sent Events.</p>
-<p>Long-polling is a mechanism in which the client performs a request which may not be immediately answered by the server. It allows clients to request resources that may not currently exist, but are expected to be created soon, and which will be returned as soon as they are.</p>
-<p>Long-polling is essentially a hack, but it is widely used to overcome limitations on older clients and servers.</p>
-<p>Server-Sent Events is a small protocol defined as a media type, <code>text/event-stream</code>, along with a new HTTP header, <code>Last-Event-ID</code>. It is defined in the EventSource W3C specification.</p>
-<p>Cowboy provides an interface known as <a href="../loop_handlers">loop handlers</a> that facilitates the implementation of long-polling or stream mechanisms. It works regardless of the underlying protocol.</p>
-<h2 id="_rest">REST</h2>
-<p><a href="../rest_principles">REST, or REpresentational State Transfer</a>, is a style of architecture for loosely connected distributed systems. It can easily be implemented on top of HTTP.</p>
-<p>REST is essentially a set of constraints to be followed. Many of these constraints are purely architectural and solved by simply using HTTP. Some constraints must be explicitly followed by the developer.</p>
-<p>Cowboy provides an interface known as <a href="../rest_handlers">REST handlers</a> that simplifies the implementation of a REST API on top of the HTTP protocol.</p>

-[[multipart]]
-== Multipart requests
-
-Multipart originates from MIME, an Internet standard that
-extends the format of emails.
-
-A multipart message is a list of parts. A part contains
-headers and a body. The body of the parts may be
-of any media type, and contain text or binary data.
-It is possible for parts to contain a multipart media
-type.
-
-In the context of HTTP, multipart is most often used
-with the `multipart/form-data` media type. It is what
-browsers use to upload files through HTML forms.
-
-The `multipart/byteranges` is also common. It is the
-media type used to send arbitrary bytes from a resource,
-enabling clients to resume downloads.
-
-=== Form-data
-
-In the normal case, when a form is submitted, the
-browser will use the `application/x-www-form-urlencoded`
-content-type. This type is just a list of keys and
-values and is therefore not fit for uploading files.
-
-That's where the `multipart/form-data` content-type
-comes in. When the form is configured to use this
-content-type, the browser will create a multipart
-message where each part corresponds to a field on
-the form. For files, it also adds some metadata in
-the part headers, like the file name.
-
-A form with a text input, a file input and a select
-choice box will result in a multipart message with
-three parts, one for each field.
-
-The browser does its best to determine the media type
-of the files it sends this way, but you should not
-rely on it for determining the contents of the file.
-Proper investigation of the contents is recommended.
-
-=== Checking for multipart messages
-
-The content-type header indicates the presence of
-a multipart message:
-
-[source,erlang]
-----
-{<<"multipart">>, <<"form-data">>, _}
-    = cowboy_req:parse_header(<<"content-type">>, Req).
-----
-
-=== Reading a multipart message
-
-Cowboy provides two sets of functions for reading
-request bodies as multipart messages.
-
-The `cowboy_req:read_part/1,2` functions return the
-next part's headers, if any.
-
-The `cowboy_req:read_part_body/1,2` functions return
-the current part's body. For large bodies you may
-need to call the function multiple times.
-
-To read a multipart message you need to iterate over
-all its parts:
-
-[source,erlang]
-----
-multipart(Req0) ->
-    case cowboy_req:read_part(Req0) of
-        {ok, _Headers, Req1} ->
-            {ok, _Body, Req} = cowboy_req:read_part_body(Req1),
-            multipart(Req);
-        {done, Req} ->
-            Req
-    end.
-----
-
-When part bodies are too large, Cowboy will return
-a `more` tuple, and allow you to loop until the part
-body has been fully read.
-
-The function `cow_multipart:form_data/1` can be used
-to quickly obtain information about a part from a
-`multipart/form-data` message. The function returns
-a `data` or a `file` tuple depending on whether this
-is a normal field or a file being uploaded.
-
-The following snippet will use this function and
-use different strategies depending on whether the
-part is a file:
-
-[source,erlang]
-----
-multipart(Req0) ->
-    case cowboy_req:read_part(Req0) of
-        {ok, Headers, Req1} ->
-            Req = case cow_multipart:form_data(Headers) of
-                {data, _FieldName} ->
-                    {ok, _Body, Req2} = cowboy_req:read_part_body(Req1),
-                    Req2;
-                {file, _FieldName, _Filename, _CType} ->
-                    stream_file(Req1)
-            end,
-            multipart(Req);
-        {done, Req} ->
-            Req
-    end.
-
-stream_file(Req0) ->
-    case cowboy_req:read_part_body(Req0) of
-        {ok, _LastBodyChunk, Req} ->
-            Req;
-        {more, _BodyChunk, Req} ->
-            stream_file(Req)
-    end.
-----
-
-Both the part header and body reading functions can take
-options that will be given to the request body reading
-functions. By default, `cowboy_req:read_part/1` reads
-up to 64KB for up to 5 seconds. `cowboy_req:read_part_body/1`
-has the same defaults as `cowboy_req:read_body/1`.
-
-To change the defaults for part headers:
-
-[source,erlang]
-cowboy_req:read_part(Req, #{length => 128000}).
-
-And for part bodies:
-
-[source,erlang]
-cowboy_req:read_part_body(Req, #{length => 1000000, period => 7000}).
-
-=== Skipping unwanted parts
-
-Part bodies do not have to be read. Cowboy will automatically
-skip it when you request the next part's body.
-
-The following snippet reads all part headers and skips
-all bodies:
-
-[source,erlang]
-----
-multipart(Req0) ->
-    case cowboy_req:read_part(Req0) of
-        {ok, _Headers, Req} ->
-            multipart(Req);
-        {done, Req} ->
-            Req
-    end.
-----
-
-Similarly, if you start reading the body and it ends up
-being too big, you can simply continue with the next part.
-Cowboy will automatically skip what remains.
-
-While Cowboy can skip part bodies automatically, the read
-rate is not configurable. Depending on your application
-you may want to skip manually, in particular if you observe
-poor performance while skipping.
-
-You do not have to read all parts either. You can stop
-reading as soon as you find the data you need.
-
-// @todo Cover the building of multipart messages.

-<p>Similarly, if you start reading the body and it ends up being too big, you can simply continue with the next part. Cowboy will automatically skip what remains.</p>
-<p>While Cowboy can skip part bodies automatically, the read rate is not configurable. Depending on your application you may want to skip manually, in particular if you observe poor performance while skipping.</p>
-<p>You do not have to read all parts either. You can stop reading as soon as you find the data you need.</p>

-[[req]]
-== The Req object
-
-The Req object is a variable used for obtaining information
-about a request, read its body or send a response.
-
-It is not really an object in the object-oriented sense.
-It is a simple map that can be directly accessed or
-used when calling functions from the `cowboy_req` module.
-
-The Req object is the subject of a few different chapters.
-In this chapter we will learn about the Req object and
-look at how to retrieve information about the request.
-
-=== Direct access
-
-The Req map contains a number of fields which are documented
-and can be accessed directly. They are the fields that have
-a direct mapping to HTTP: the request `method`; the HTTP
-`version` used; the effective URI components `scheme`,
-`host`, `port`, `path` and `qs`; the request `headers`;
-and the connection `peer` address and port.
-
-Note that the `version` field can be used to determine
-whether a connection is using HTTP/2.
-
-To access a field, you can simply match in the function
-head. The following example sends a simple "Hello world!"
-response when the `method` is GET, and a 405 error
-otherwise.
-
-[source,erlang]
-----
-init(Req0=#{method := <<"GET">>}, State) ->
-    Req = cowboy_req:reply(200, #{
-        <<"content-type">> => <<"text/plain">>
-    }, <<"Hello world!">>, Req0),
-    {ok, Req, State};
-init(Req0, State) ->
-    Req = cowboy_req:reply(405, #{
-        <<"allow">> => <<"GET">>
-    }, Req0),
-    {ok, Req, State}.
-----
-
-Any other field is internal and should not be accessed.
-They may change in future releases, including maintenance
-releases, without notice.
-
-Modifying the Req object, while allowed, is not recommended
-unless strictly necessary. If adding new fields, make sure
-to namespace the field names so that no conflict can occur
-with future Cowboy updates or third party projects.
-
-// @todo There are currently no tests for direct access.
-
-=== Introduction to the cowboy_req interface
-
-// @todo Link to cowboy_req manual
-
-Functions in the `cowboy_req` module provide access to
-the request information but also various operations that
-are common when dealing with HTTP requests.
-
-All the functions that begin with a verb indicate an action.
-Other functions simply return the corresponding value
-(sometimes that value does need to be built, but the
-cost of the operation is equivalent to retrieving a value).
-
-Some of the `cowboy_req` functions return an updated Req
-object. They are the read, reply, set and delete functions.
-While ignoring the returned Req will not cause incorrect
-behavior for some of them, it is highly recommended to
-always keep and use the last returned Req object. The
-manual for `cowboy_req` details these functions and what
-modifications are done to the Req object.
-
-Some of the calls to `cowboy_req` have side effects. This
-is the case of the read and reply functions. Cowboy reads
-the request body or replies immediately when the function
-is called.
-
-All functions will crash if something goes wrong. There
-is usually no need to catch these errors, Cowboy will
-send the appropriate 4xx or 5xx response depending on
-where the crash occurred.
-
-=== Request method
-
-The request method can be retrieved directly:
-
-[source, erlang]
-#{method := Method} = Req.
-
-Or using a function:
-
-[source,erlang]
-Method = cowboy_req:method(Req).
-
-The method is a case sensitive binary string. Standard
-methods include GET, HEAD, OPTIONS, PATCH, POST, PUT
-or DELETE.
-
-=== HTTP version
-
-The HTTP version is informational. It does not indicate that
-the client implements the protocol well or fully.
-
-There is typically no need to change behavior based on the
-HTTP version: Cowboy already does it for you.
-
-It can be useful in some cases, though. For example, one may
-want to redirect HTTP/1.1 clients to use Websocket, while HTTP/2
-clients keep using HTTP/2.
-
-The HTTP version can be retrieved directly:
-
-[source,erlang]
-#{version := Version} = Req.
-
-Or using a function:
-
-[source,erlang]
-Version = cowboy_req:version(Req).
-
-Cowboy defines the `'HTTP/1.0'`, `'HTTP/1.1'` and `'HTTP/2'`
-versions. Custom protocols can define their own values as
-atoms.
-
-=== Effective request URI
-
-The scheme, host, port, path and query string components
-of the effective request URI can all be retrieved directly:
-
-[source,erlang]
-----
-#{
-    scheme := Scheme,
-    host := Host,
-    port := Port,
-    path := Path,
-    qs := Qs
-} = Req.
-----
-
-Or using the related functions:
-
-[source,erlang]
-Scheme = cowboy_req:scheme(Req),
-Host = cowboy_req:host(Req),
-Port = cowboy_req:port(Req),
-Path = cowboy_req:path(Req).
-Qs = cowboy_req:qs(Req).
-
-The scheme and host are lowercased case insensitive binary
-strings. The port is an integer representing the port number.
-The path and query string are case sensitive binary strings.
-
-Cowboy defines only the `<<"http">>` and `<<"https">>` schemes.
-They are chosen so that the scheme will only be `<<"https">>`
-for requests on secure HTTP/1.1 or HTTP/2 connections.
-// @todo Is that tested well?
-
-The effective request URI itself can be reconstructed with
-the `cowboy_req:uri/1,2` function. By default, an absolute
-URI is returned:
-
-[source,erlang]
-%% scheme://host[:port]/path[?qs]
-URI = cowboy_req:uri(Req).
-
-Options are available to either disable or replace some
-or all of the components. Various URIs or URI formats can
-be generated this way, including the origin form:
-
-[source,erlang]
-%% /path[?qs]
-URI = cowboy_req:uri(Req, #{host => undefined}).
-
-The protocol relative form:
-
-[source,erlang]
-%% //host[:port]/path[?qs]
-URI = cowboy_req:uri(Req, #{scheme => undefined}).
-
-The absolute URI without a query string:
-
-[source,erlang]
-URI = cowboy_req:uri(Req, #{qs => undefined}).
-
-A different host:
-
-[source,erlang]
-URI = cowboy_req:uri(Req, #{host => <<"example.org">>}).
-
-And any other combination.
-
-=== Bindings
-
-Bindings are the host and path components that you chose
-to extract when defining the routes of your application.
-They are only available after the routing.
-
-Cowboy provides functions to retrieve one or all bindings.
-
-To retrieve a single value:
-
-[source,erlang]
-Value = cowboy_req:binding(userid, Req).
-
-When attempting to retrieve a value that was not bound,
-`undefined` will be returned. A different default value
-can be provided:
-
-[source,erlang]
-Value = cowboy_req:binding(userid, Req, 42).
-
-To retrieve everything that was bound:
-
-[source,erlang]
-Bindings = cowboy_req:bindings(Req).
-
-They are returned as a map, with keys being atoms.
-
-The Cowboy router also allows you to capture many host
-or path segments at once using the `...` qualifier.
-
-To retrieve the segments captured from the host name:
-
-[source,erlang]
-HostInfo = cowboy_req:host_info(Req).
-
-And the path segments:
-
-[source,erlang]
-PathInfo = cowboy_req:path_info(Req).
-
-Cowboy will return `undefined` if `...` was not used
-in the route.
-
-=== Query parameters
-
-Cowboy provides two functions to access query parameters.
-You can use the first to get the entire list of parameters.
-
-[source,erlang]
-QsVals = cowboy_req:parse_qs(Req),
-{_, Lang} = lists:keyfind(<<"lang">>, 1, QsVals).
-
-Cowboy will only parse the query string, and not do any
-transformation. This function may therefore return duplicates,
-or parameter names without an associated value. The order of
-the list returned is undefined.
-
-When a query string is `key=1&key=2`, the list returned will
-contain two parameters of name `key`.
-
-The same is true when trying to use the PHP-style suffix `[]`.
-When a query string is `key[]=1&key[]=2`, the list returned will
-contain two parameters of name `key[]`.
-
-When a query string is simply `key`, Cowboy will return the
-list `[{<<"key">>, true}]`, using `true` to indicate that the
-parameter `key` was defined, but with no value.
-
-The second function Cowboy provides allows you to match out
-only the parameters you are interested in, and at the same
-time do any post processing you require using xref:constraints[constraints].
-This function returns a map.
-
-[source,erlang]
-#{id := ID, lang := Lang} = cowboy_req:match_qs([id, lang], Req).
-
-Constraints can be applied automatically. The following
-snippet will crash when the `id` parameter is not an integer,
-or when the `lang` parameter is empty. At the same time, the
-value for `id` will be converted to an integer term:
-
-[source,erlang]
-QsMap = cowboy_req:match_qs([{id, int}, {lang, nonempty}], Req).
-
-A default value may also be provided. The default will be used
-if the `lang` key is not found. It will not be used if
-the key is found but has an empty value.
-
-[source,erlang]
-#{lang := Lang} = cowboy_req:match_qs([{lang, [], <<"en-US">>}], Req).
-
-If no default is provided and the value is missing, the
-query string is deemed invalid and the process will crash.
-
-When the query string is `key=1&key=2`, the value for `key`
-will be the list `[1, 2]`. Parameter names do not need to
-include the PHP-style suffix. Constraints may be used to
-ensure that only one value was passed through.
-
-=== Headers
-
-Header values can be retrieved either as a binary string
-or parsed into a more meaningful representation.
-
-The get the raw value:
-
-[source,erlang]
-HeaderVal = cowboy_req:header(<<"content-type">>, Req).
-
-Cowboy expects all header names to be provided as lowercase
-binary strings. This is true for both requests and responses,
-regardless of the underlying protocol.
-
-When the header is missing from the request, `undefined`
-will be returned. A different default can be provided:
-
-[source,erlang]
-HeaderVal = cowboy_req:header(<<"content-type">>, Req, <<"text/plain">>).
-
-All headers can be retrieved at once, either directly:
-
-[source,erlang]
-#{headers := AllHeaders} = Req.
-
-Or using a function:
-
-[source,erlang]
-AllHeaders = cowboy_req:headers(Req).
-
-Cowboy provides equivalent functions to parse individual
-headers. There is no function to parse all headers at once.
-
-To parse a specific header:
-
-[source,erlang]
-ParsedVal = cowboy_req:parse_header(<<"content-type">>, Req).
-
-An exception will be thrown if it doesn't know how to parse the
-given header, or if the value is invalid. The list of known headers
-and default values can be found in the manual.
-
-When the header is missing, `undefined` is returned. You can
-change the default value. Note that it should be the parsed value
-directly:
-
-[source,erlang]
-----
-ParsedVal = cowboy_req:parse_header(<<"content-type">>, Req,
-    {<<"text">>, <<"plain">>, []}).
-----
-
-=== Peer
-
-The peer address and port number for the connection can be
-retrieved either directly or using a function.
-
-To retrieve the peer directly:
-
-[source,erlang]
-#{peer := {IP, Port}} = Req.
-
-And using a function:
-
-[source,erlang]
-{IP, Port} = cowboy_req:peer(Req).
-
-Note that the peer corresponds to the remote end of the
-connection to the server, which may or may not be the
-client itself. It may also be a proxy or a gateway.

-
-<p>The Req object is a variable used for obtaining information about a request, read its body or send a response.</p>
-<p>It is not really an object in the object-oriented sense. It is a simple map that can be directly accessed or used when calling functions from the <code>cowboy_req</code> module.</p>
-<p>The Req object is the subject of a few different chapters. In this chapter we will learn about the Req object and look at how to retrieve information about the request.</p>
-<h2 id="_direct_access">Direct access</h2>
-<p>The Req map contains a number of fields which are documented and can be accessed directly. They are the fields that have a direct mapping to HTTP: the request <code>method</code>; the HTTP <code>version</code> used; the effective URI components <code>scheme</code>, <code>host</code>, <code>port</code>, <code>path</code> and <code>qs</code>; the request <code>headers</code>; and the connection <code>peer</code> address and port.</p>
-<p>Note that the <code>version</code> field can be used to determine whether a connection is using HTTP/2.</p>
-<p>To access a field, you can simply match in the function head. The following example sends a simple &quot;Hello world!&quot; response when the <code>method</code> is GET, and a 405 error otherwise.</p>

-<p>Any other field is internal and should not be accessed. They may change in future releases, including maintenance releases, without notice.</p>
-<p>Modifying the Req object, while allowed, is not recommended unless strictly necessary. If adding new fields, make sure to namespace the field names so that no conflict can occur with future Cowboy updates or third party projects.</p>
-<!-- @todo There are currently no tests for direct access.-->
-<h2 id="_introduction_to_the_cowboy_req_interface">Introduction to the cowboy_req interface</h2>
-<!-- @todo Link to cowboy_req manual-->
-<p>Functions in the <code>cowboy_req</code> module provide access to the request information but also various operations that are common when dealing with HTTP requests.</p>
-<p>All the functions that begin with a verb indicate an action. Other functions simply return the corresponding value (sometimes that value does need to be built, but the cost of the operation is equivalent to retrieving a value).</p>
-<p>Some of the <code>cowboy_req</code> functions return an updated Req object. They are the read, reply, set and delete functions. While ignoring the returned Req will not cause incorrect behavior for some of them, it is highly recommended to always keep and use the last returned Req object. The manual for <code>cowboy_req</code> details these functions and what modifications are done to the Req object.</p>
-<p>Some of the calls to <code>cowboy_req</code> have side effects. This is the case of the read and reply functions. Cowboy reads the request body or replies immediately when the function is called.</p>
-<p>All functions will crash if something goes wrong. There is usually no need to catch these errors, Cowboy will send the appropriate 4xx or 5xx response depending on where the crash occurred.</p>

-<p>Cowboy will only parse the query string, and not do any transformation. This function may therefore return duplicates, or parameter names without an associated value. The order of the list returned is undefined.</p>
-<p>When a query string is <code>key=1&amp;key=2</code>, the list returned will contain two parameters of name <code>key</code>.</p>
-<p>The same is true when trying to use the PHP-style suffix <code>[]</code>. When a query string is <code>key[]=1&amp;key[]=2</code>, the list returned will contain two parameters of name <code>key[]</code>.</p>
-<p>When a query string is simply <code>key</code>, Cowboy will return the list <code>[{&lt;&lt;&quot;key&quot;&gt;&gt;, true}]</code>, using <code>true</code> to indicate that the parameter <code>key</code> was defined, but with no value.</p>
-<p>The second function Cowboy provides allows you to match out only the parameters you are interested in, and at the same time do any post processing you require using <a href="../constraints">constraints</a>. This function returns a map.</p>

-[[req_body]]
-== Reading the request body
-
-The request body can be read using the Req object.
-
-Cowboy will not attempt to read the body until requested.
-You need to call the body reading functions in order to
-retrieve it.
-
-Cowboy will not cache the body, it is therefore only
-possible to read it once.
-
-You are not required to read it, however. If a body is
-present and was not read, Cowboy will either cancel or
-skip its download, depending on the protocol.
-
-Cowboy provides functions for reading the body raw,
-and read and parse form urlencoded or xref:multipart[multipart bodies].
-The latter is covered in its own chapter.
-
-=== Request body presence
-
-Not all requests come with a body. You can check for
-the presence of a request body with this function:
-
-[source,erlang]
-cowboy_req:has_body(Req).
-
-It returns `true` if there is a body; `false` otherwise.
-
-In practice, this function is rarely used. When the
-method is `POST`, `PUT` or `PATCH`, the request body
-is often required by the application, which should
-just attempt to read it directly.
-
-=== Request body length
-
-You can obtain the length of the body:
-
-[source,erlang]
-Length = cowboy_req:body_length(Req).
-
-Note that the length may not be known in advance. In
-that case `undefined` will be returned. This can happen
-with HTTP/1.1's chunked transfer-encoding, or HTTP/2
-when no content-length was provided.
-
-Cowboy will update the body length in the Req object
-once the body has been read completely. A length will
-always be returned when attempting to call this function
-after reading the body completely.
-
-=== Reading the body
-
-You can read the entire body with one function call:
-
-[source,erlang]
-{ok, Data, Req} = cowboy_req:read_body(Req0).
-
-Cowboy returns an `ok` tuple when the body has been
-read fully.
-
-By default, Cowboy will attempt to read up to 8MB
-of data, for up to 15 seconds. The call will return
-once Cowboy has read at least 8MB of data, or at
-the end of the 15 seconds period.
-
-These values can be customized. For example, to read
-only up to 1MB for up to 5 seconds:
-
-[source,erlang]
-----
-{ok, Data, Req} = cowboy_req:read_body(Req0,
-    #{length => 1000000, period => 5000}).
-----
-
-You may also disable the length limit:
-
-[source,erlang]
-{ok, Data, Req} = cowboy_req:read_body(Req0, #{length => infinity}).
-
-This makes the function wait 15 seconds and return with
-whatever arrived during that period. This is not
-recommended for public facing applications.
-
-These two options can effectively be used to control
-the rate of transmission of the request body.
-
-=== Streaming the body
-
-When the body is too large, the first call will return
-a `more` tuple instead of `ok`. You can call the
-function again to read more of the body, reading
-it one chunk at a time.
-
-[source,erlang]
-----
-read_body_to_console(Req0) ->
-    case cowboy_req:read_body(Req0) of
-        {ok, Data, Req} ->
-            io:format("~s", [Data]),
-            Req;
-        {more, Data, Req} ->
-            io:format("~s", [Data]),
-            read_body_to_console(Req)
-    end.
-----
-
-The `length` and `period` options can also be used.
-They need to be passed for every call.
-
-=== Reading a form urlencoded body
-
-Cowboy provides a convenient function for reading and
-parsing bodies sent as application/x-www-form-urlencoded.
-
-[source,erlang]
-{ok, KeyValues, Req} = cowboy_req:read_urlencoded_body(Req0).
-
-This function returns a list of key/values, exactly like
-the function `cowboy_req:parse_qs/1`.
-
-The defaults for this function are different. Cowboy will
-read for up to 64KB and up to 5 seconds. They can be modified:
-
-[source,erlang]
-----
-{ok, KeyValues, Req} = cowboy_req:read_urlencoded_body(Req0,
-    #{length => 4096, period => 3000}).

-<h1 class="lined-header"><span>Reading the request body</span></h1>
-
-<p>The request body can be read using the Req object.</p>
-<p>Cowboy will not attempt to read the body until requested. You need to call the body reading functions in order to retrieve it.</p>
-<p>Cowboy will not cache the body, it is therefore only possible to read it once.</p>
-<p>You are not required to read it, however. If a body is present and was not read, Cowboy will either cancel or skip its download, depending on the protocol.</p>
-<p>Cowboy provides functions for reading the body raw, and read and parse form urlencoded or <a href="../multipart">multipart bodies</a>. The latter is covered in its own chapter.</p>
-<h2 id="_request_body_presence">Request body presence</h2>
-<p>Not all requests come with a body. You can check for the presence of a request body with this function:</p>

-</div></div>
-<p>It returns <code>true</code> if there is a body; <code>false</code> otherwise.</p>
-<p>In practice, this function is rarely used. When the method is <code>POST</code>, <code>PUT</code> or <code>PATCH</code>, the request body is often required by the application, which should just attempt to read it directly.</p>
-<h2 id="_request_body_length">Request body length</h2>
-<p>You can obtain the length of the body:</p>

-</div></div>
-<p>Note that the length may not be known in advance. In that case <code>undefined</code> will be returned. This can happen with HTTP/1.1&apos;s chunked transfer-encoding, or HTTP/2 when no content-length was provided.</p>
-<p>Cowboy will update the body length in the Req object once the body has been read completely. A length will always be returned when attempting to call this function after reading the body completely.</p>
-<h2 id="_reading_the_body">Reading the body</h2>
-<p>You can read the entire body with one function call:</p>

-</div></div>
-<p>Cowboy returns an <code>ok</code> tuple when the body has been read fully.</p>
-<p>By default, Cowboy will attempt to read up to 8MB of data, for up to 15 seconds. The call will return once Cowboy has read at least 8MB of data, or at the end of the 15 seconds period.</p>
-<p>These values can be customized. For example, to read only up to 1MB for up to 5 seconds:</p>

-<p>This makes the function wait 15 seconds and return with whatever arrived during that period. This is not recommended for public facing applications.</p>

-[[resource_design]]
-== Designing a resource handler
-
-This chapter aims to provide you with a list of questions
-you must answer in order to write a good resource handler.
-It is meant to be usable as a step by step guide.
-
-=== The service
-
-Can the service become unavailable, and when it does, can
-we detect it? For example, database connectivity problems
-may be detected early. We may also have planned outages
-of all or parts of the system. Implement the
-`service_available` callback.
-
-What HTTP methods does the service implement? Do we need
-more than the standard OPTIONS, HEAD, GET, PUT, POST,
-PATCH and DELETE? Are we not using one of those at all?
-Implement the `known_methods` callback.
-
-=== Type of resource handler
-
-Am I writing a handler for a collection of resources,
-or for a single resource?
-
-The semantics for each of these are quite different.
-You should not mix collection and single resource in
-the same handler.
-
-=== Collection handler
-
-Skip this section if you are not doing a collection.
-
-Is the collection hardcoded or dynamic? For example,
-if you use the route `/users` for the collection of
-users then the collection is hardcoded; if you use
-`/forums/:category` for the collection of threads
-then it isn't. When the collection is hardcoded you
-can safely assume the resource always exists.
-
-What methods should I implement?
-
-OPTIONS is used to get some information about the
-collection. It is recommended to allow it even if you
-do not implement it, as Cowboy has a default
-implementation built-in.
-
-HEAD and GET are used to retrieve the collection.
-If you allow GET, also allow HEAD as there's no extra
-work required to make it work.
-
-POST is used to create a new resource inside the
-collection. Creating a resource by using POST on
-the collection is useful when resources may be
-created before knowing their URI, usually because
-parts of it are generated dynamically. A common
-case is some kind of auto incremented integer
-identifier.
-
-The next methods are more rarely allowed.
-
-PUT is used to create a new collection (when
-the collection isn't hardcoded), or replace
-the entire collection.
-
-DELETE is used to delete the entire collection.
-
-PATCH is used to modify the collection using
-instructions given in the request body. A PATCH
-operation is atomic. The PATCH operation may
-be used for such things as reordering; adding,
-modifying or deleting parts of the collection.
-
-=== Single resource handler
-
-Skip this section if you are doing a collection.
-
-What methods should I implement?
-
-OPTIONS is used to get some information about the
-resource. It is recommended to allow it even if you
-do not implement it, as Cowboy has a default
-implementation built-in.
-
-HEAD and GET are used to retrieve the resource.
-If you allow GET, also allow HEAD as there's no extra
-work required to make it work.
-
-POST is used to update the resource.
-
-PUT is used to create a new resource (when it doesn't
-already exist) or replace the resource.
-
-DELETE is used to delete the resource.
-
-PATCH is used to modify the resource using
-instructions given in the request body. A PATCH
-operation is atomic. The PATCH operation may
-be used for adding, removing or modifying specific
-values in the resource.
-
-=== The resource
-
-Following the above discussion, implement the
-`allowed_methods` callback.
-
-Does the resource always exist? If it may not, implement
-the `resource_exists` callback.
-
-Do I need to authenticate the client before they can
-access the resource? What authentication mechanisms
-should I provide? This may include form-based, token-based
-(in the URL or a cookie), HTTP basic, HTTP digest,
-SSL certificate or any other form of authentication.
-Implement the `is_authorized` callback.
-
-Do I need fine-grained access control? How do I determine
-that they are authorized access? Handle that in your
-`is_authorized` callback.
-
-Can access to a resource be forbidden regardless of access
-being authorized? A simple example of that is censorship
-of a resource. Implement the `forbidden` callback.
-
-Are there any constraints on the length of the resource URI?
-For example, the URI may be used as a key in storage and may
-have a limit in length. Implement `uri_too_long`.
-
-=== Representations
-
-What media types do I provide? If text based, what charsets
-are provided? What languages do I provide?
-
-Implement the mandatory `content_types_provided`. Prefix
-the callbacks with `to_` for clarity. For example, `to_html`
-or `to_text`.
-
-Implement the `languages_provided` or `charsets_provided`
-callbacks if applicable.
-
-Is there any other header that may make the representation
-of the resource vary? Implement the `variances` callback.
-
-Depending on your choices for caching content, you may
-want to implement one or more of the `generate_etag`,
-`last_modified` and `expires` callbacks.
-
-Do I want the user or user agent to actively choose a
-representation available? Send a list of available
-representations in the response body and implement
-the `multiple_choices` callback.
-
-=== Redirections
-
-Do I need to keep track of what resources were deleted?
-For example, you may have a mechanism where moving a
-resource leaves a redirect link to its new location.
-Implement the `previously_existed` callback.
-
-Was the resource moved, and is the move temporary? If
-it is explicitly temporary, for example due to maintenance,
-implement the `moved_temporarily` callback. Otherwise,
-implement the `moved_permanently` callback.
-
-=== The request
-
-Do you need to read the query string? Individual headers?
-Implement `malformed_request` and do all the parsing and
-validation in this function. Note that the body should not
-be read at this point.
-
-May there be a request body? Will I know its size?
-What's the maximum size of the request body I'm willing
-to accept? Implement `valid_entity_length`.
-
-Finally, take a look at the sections corresponding to the
-methods you are implementing.
-
-=== OPTIONS method
-
-Cowboy by default will send back a list of allowed methods.
-Do I need to add more information to the response? Implement
-the `options` method.
-
-=== GET and HEAD methods
-
-If you implement the methods GET and/or HEAD, you must
-implement one `ProvideResource` callback for each
-content-type returned by the `content_types_provided`
-callback.
-
-=== PUT, POST and PATCH methods
-
-If you implement the methods PUT, POST and/or PATCH,
-you must implement the `content_types_accepted` callback,
-and one `AcceptResource` callback for each content-type
-it returns. Prefix the `AcceptResource` callback names
-with `from_` for clarity. For example, `from_html` or
-`from_json`.
-
-Do we want to allow the POST method to create individual
-resources directly through their URI (like PUT)? Implement
-the `allow_missing_post` callback. It is recommended to
-explicitly use PUT in these cases instead.
-
-May there be conflicts when using PUT to create or replace
-a resource? Do we want to make sure that two updates around
-the same time are not cancelling one another? Implement the
-`is_conflict` callback.
-
-=== DELETE methods
-
-If you implement the method DELETE, you must implement
-the `delete_resource` callback.
-
-When `delete_resource` returns, is the resource completely
-removed from the server, including from any caching service?
-If not, and/or if the deletion is asynchronous and we have
-no way of knowing it has been completed yet, implement the
-`delete_completed` callback.

-<h1 class="lined-header"><span>Designing a resource handler</span></h1>
-
-<p>This chapter aims to provide you with a list of questions you must answer in order to write a good resource handler. It is meant to be usable as a step by step guide.</p>
-<h2 id="_the_service">The service</h2>
-<p>Can the service become unavailable, and when it does, can we detect it? For example, database connectivity problems may be detected early. We may also have planned outages of all or parts of the system. Implement the <code>service_available</code> callback.</p>
-<p>What HTTP methods does the service implement? Do we need more than the standard OPTIONS, HEAD, GET, PUT, POST, PATCH and DELETE? Are we not using one of those at all? Implement the <code>known_methods</code> callback.</p>
-<h2 id="_type_of_resource_handler">Type of resource handler</h2>
-<p>Am I writing a handler for a collection of resources, or for a single resource?</p>
-<p>The semantics for each of these are quite different. You should not mix collection and single resource in the same handler.</p>
-<h2 id="_collection_handler">Collection handler</h2>
-<p>Skip this section if you are not doing a collection.</p>
-<p>Is the collection hardcoded or dynamic? For example, if you use the route <code>/users</code> for the collection of users then the collection is hardcoded; if you use <code>/forums/:category</code> for the collection of threads then it isn&apos;t. When the collection is hardcoded you can safely assume the resource always exists.</p>
-<p>What methods should I implement?</p>
-<p>OPTIONS is used to get some information about the collection. It is recommended to allow it even if you do not implement it, as Cowboy has a default implementation built-in.</p>
-<p>HEAD and GET are used to retrieve the collection. If you allow GET, also allow HEAD as there&apos;s no extra work required to make it work.</p>
-<p>POST is used to create a new resource inside the collection. Creating a resource by using POST on the collection is useful when resources may be created before knowing their URI, usually because parts of it are generated dynamically. A common case is some kind of auto incremented integer identifier.</p>
-<p>The next methods are more rarely allowed.</p>
-<p>PUT is used to create a new collection (when the collection isn&apos;t hardcoded), or replace the entire collection.</p>
-<p>DELETE is used to delete the entire collection.</p>
-<p>PATCH is used to modify the collection using instructions given in the request body. A PATCH operation is atomic. The PATCH operation may be used for such things as reordering; adding, modifying or deleting parts of the collection.</p>
-<h2 id="_single_resource_handler">Single resource handler</h2>
-<p>Skip this section if you are doing a collection.</p>
-<p>What methods should I implement?</p>
-<p>OPTIONS is used to get some information about the resource. It is recommended to allow it even if you do not implement it, as Cowboy has a default implementation built-in.</p>
-<p>HEAD and GET are used to retrieve the resource. If you allow GET, also allow HEAD as there&apos;s no extra work required to make it work.</p>
-<p>POST is used to update the resource.</p>
-<p>PUT is used to create a new resource (when it doesn&apos;t already exist) or replace the resource.</p>
-<p>DELETE is used to delete the resource.</p>
-<p>PATCH is used to modify the resource using instructions given in the request body. A PATCH operation is atomic. The PATCH operation may be used for adding, removing or modifying specific values in the resource.</p>
-<h2 id="_the_resource">The resource</h2>
-<p>Following the above discussion, implement the <code>allowed_methods</code> callback.</p>
-<p>Does the resource always exist? If it may not, implement the <code>resource_exists</code> callback.</p>
-<p>Do I need to authenticate the client before they can access the resource? What authentication mechanisms should I provide? This may include form-based, token-based (in the URL or a cookie), HTTP basic, HTTP digest, SSL certificate or any other form of authentication. Implement the <code>is_authorized</code> callback.</p>
-<p>Do I need fine-grained access control? How do I determine that they are authorized access? Handle that in your <code>is_authorized</code> callback.</p>
-<p>Can access to a resource be forbidden regardless of access being authorized? A simple example of that is censorship of a resource. Implement the <code>forbidden</code> callback.</p>
-<p>Are there any constraints on the length of the resource URI? For example, the URI may be used as a key in storage and may have a limit in length. Implement <code>uri_too_long</code>.</p>
-<h2 id="_representations">Representations</h2>
-<p>What media types do I provide? If text based, what charsets are provided? What languages do I provide?</p>
-<p>Implement the mandatory <code>content_types_provided</code>. Prefix the callbacks with <code>to_</code> for clarity. For example, <code>to_html</code> or <code>to_text</code>.</p>
-<p>Implement the <code>languages_provided</code> or <code>charsets_provided</code> callbacks if applicable.</p>
-<p>Is there any other header that may make the representation of the resource vary? Implement the <code>variances</code> callback.</p>
-<p>Depending on your choices for caching content, you may want to implement one or more of the <code>generate_etag</code>, <code>last_modified</code> and <code>expires</code> callbacks.</p>
-<p>Do I want the user or user agent to actively choose a representation available? Send a list of available representations in the response body and implement the <code>multiple_choices</code> callback.</p>
-<h2 id="_redirections">Redirections</h2>
-<p>Do I need to keep track of what resources were deleted? For example, you may have a mechanism where moving a resource leaves a redirect link to its new location. Implement the <code>previously_existed</code> callback.</p>
-<p>Was the resource moved, and is the move temporary? If it is explicitly temporary, for example due to maintenance, implement the <code>moved_temporarily</code> callback. Otherwise, implement the <code>moved_permanently</code> callback.</p>
-<h2 id="_the_request">The request</h2>
-<p>Do you need to read the query string? Individual headers? Implement <code>malformed_request</code> and do all the parsing and validation in this function. Note that the body should not be read at this point.</p>
-<p>May there be a request body? Will I know its size? What&apos;s the maximum size of the request body I&apos;m willing to accept? Implement <code>valid_entity_length</code>.</p>
-<p>Finally, take a look at the sections corresponding to the methods you are implementing.</p>
-<h2 id="_options_method">OPTIONS method</h2>
-<p>Cowboy by default will send back a list of allowed methods. Do I need to add more information to the response? Implement the <code>options</code> method.</p>
-<h2 id="_get_and_head_methods">GET and HEAD methods</h2>
-<p>If you implement the methods GET and/or HEAD, you must implement one <code>ProvideResource</code> callback for each content-type returned by the <code>content_types_provided</code> callback.</p>
-<h2 id="_put__post_and_patch_methods">PUT, POST and PATCH methods</h2>
-<p>If you implement the methods PUT, POST and/or PATCH, you must implement the <code>content_types_accepted</code> callback, and one <code>AcceptResource</code> callback for each content-type it returns. Prefix the <code>AcceptResource</code> callback names with <code>from_</code> for clarity. For example, <code>from_html</code> or <code>from_json</code>.</p>
-<p>Do we want to allow the POST method to create individual resources directly through their URI (like PUT)? Implement the <code>allow_missing_post</code> callback. It is recommended to explicitly use PUT in these cases instead.</p>
-<p>May there be conflicts when using PUT to create or replace a resource? Do we want to make sure that two updates around the same time are not cancelling one another? Implement the <code>is_conflict</code> callback.</p>
-<h2 id="_delete_methods">DELETE methods</h2>
-<p>If you implement the method DELETE, you must implement the <code>delete_resource</code> callback.</p>
-<p>When <code>delete_resource</code> returns, is the resource completely removed from the server, including from any caching service? If not, and/or if the deletion is asynchronous and we have no way of knowing it has been completed yet, implement the <code>delete_completed</code> callback.</p>

-== Sending a response
-
-The response must be sent using the Req object.
-
-Cowboy provides two different ways of sending responses:
-either directly or by streaming the body. Response headers
-and body may be set in advance. The response is sent as
-soon as one of the reply or stream reply function is
-called.
-
-Cowboy also provides a simplified interface for sending
-files. It can also send only specific parts of a file.
-
-While only one response is allowed for every request,
-HTTP/2 introduced a mechanism that allows the server
-to push additional resources related to the response.
-This chapter also describes how this feature works in
-Cowboy.
-
-=== Reply
-
-Cowboy provides three functions for sending the entire reply,
-depending on whether you need to set headers and body. In all
-cases, Cowboy will add any headers required by the protocol
-(for example the date header will always be sent).
-
-When you need to set only the status code,
-use `cowboy_req:reply/2`:
-
-[source,erlang]
-Req = cowboy_req:reply(200, Req0).
-
-When you need to set response headers at the same time,
-use `cowboy_req:reply/3`:
-
-[source,erlang]
-----
-Req = cowboy_req:reply(303, #{
-    <<"location">> => <<"https://ninenines.eu">>
-}, Req0).
-----
-
-Note that the header name must always be a lowercase
-binary.
-
-When you also need to set the response body,
-use `cowboy_req:reply/4`:
-
-[source,erlang]
-----
-Req = cowboy_req:reply(200, #{
-    <<"content-type">> => <<"text/plain">>
-}, "Hello world!", Req0).
-----
-
-You should always set the content-type header when the
-response has a body. There is however no need to set
-the content-length header; Cowboy does it automatically.
-
-The response body and the header values must be either
-a binary or an iolist. An iolist is a list containing
-binaries, characters, strings or other iolists. This
-allows you to build a response from different parts
-without having to do any concatenation:
-
-[source,erlang]
-----
-Title = "Hello world!",
-Body = <<"Hats off!">>,
-Req = cowboy_req:reply(200, #{
-    <<"content-type">> => <<"text/html">>
-}, ["<html><head><title>", Title, "</title></head>",
-    "<body><p>", Body, "</p></body></html>"], Req0).
-----
-
-This method of building responses is more efficient than
-concatenating. Behind the scenes, each element of the list
-is simply a pointer, and those pointers are used directly
-when writing to the socket.
-
-=== Stream reply
-
-Cowboy provides two functions for initiating a response,
-and an additional function for streaming the response body.
-Cowboy will add any required headers to the response.
-
-// @todo For HTTP/1.1 Cowboy should probably not use chunked transfer-encoding if the content-length is set.
-
-When you need to set only the status code,
-use `cowboy_req:stream_reply/2`:
-
-[source,erlang]
-----
-Req = cowboy_req:stream_reply(200, Req0),
-
-cowboy_req:stream_body("Hello...", nofin, Req),
-cowboy_req:stream_body("chunked...", nofin, Req),
-cowboy_req:stream_body("world!!", fin, Req).
-----
-
-The second argument to `cowboy_req:stream_body/3` indicates
-whether this data terminates the body. Use `fin` for the
-final flag, and `nofin` otherwise.
-
-This snippet does not set a content-type header. This is
-not recommended. All responses with a body should have
-a content-type. The header can be set beforehand, or
-using the `cowboy_req:stream_reply/3`:
-
-[source,erlang]
-----
-Req = cowboy_req:stream_reply(200, #{
-    <<"content-type">> => <<"text/html">>
-}, Req0),
-
-cowboy_req:stream_body("<html><head>Hello world!</head>", nofin, Req),
-cowboy_req:stream_body("<body><p>Hats off!</p></body></html>", fin, Req).
-----
-
-HTTP provides a few different ways to stream response bodies.
-Cowboy will select the most appropriate one based on the HTTP
-version and the request and response headers.
-
-While not required by any means, it is recommended that you
-set the content-length header in the response if you know it
-in advance. This will ensure that the best response method
-is selected and help clients understand when the response
-is fully received.
-
-// @todo Document trailers here.
-
-=== Preset response headers
-
-Cowboy provides functions to set response headers without
-immediately sending them. They are stored in the Req object
-and sent as part of the response when a reply function is
-called.
-
-To set response headers:
-
-[source,erlang]
-Req = cowboy_req:set_resp_header(<<"allow">>, "GET", Req0).
-
-Header names must be a lowercase binary.
-
-Do not use this function for setting cookies. Refer to
-the xref:cookies[Cookies] chapter for more information.
-
-To check if a response header has already been set:
-
-[source,erlang]
-cowboy_req:has_resp_header(<<"allow">>, Req).
-
-It returns `true` if the header was set, `false` otherwise.
-
-To delete a response header that was set previously:
-
-[source,erlang]
-Req = cowboy_req:delete_resp_header(<<"allow">>, Req0).
-
-=== Overriding headers
-
-As Cowboy provides different ways of setting response
-headers and body, clashes may occur, so it's important
-to understand what happens when a header is set twice.
-
-Headers come from five different origins:
-
-* Protocol-specific headers (for example HTTP/1.1's connection header)
-* Other required headers (for example the date header)
-* Preset headers
-* Headers given to the reply function
-* Set-cookie headers
-
-Cowboy does not allow overriding protocol-specific headers.
-
-Set-cookie headers will always be appended at the end of
-the list of headers before sending the response.
-
-Headers given to the reply function will always override
-preset headers and required headers. If a header is found
-in two or three of these, then the one in the reply function
-is picked and the others are dropped.
-
-Similarly, preset headers will always override required
-headers.
-
-To illustrate, look at the following snippet. Cowboy by
-default sends the server header with the value "Cowboy".
-We can override it:
-
-[source,erlang]
-----
-Req = cowboy_req:reply(200, #{
-    <<"server">> => <<"yaws">>
-}, Req0).
-----
-
-=== Preset response body
-
-Cowboy provides functions to set the response body without
-immediately sending it. It is stored in the Req object and
-sent when the reply function is called.
-
-To set the response body:
-
-[source,erlang]
-Req = cowboy_req:set_resp_body("Hello world!", Req0).
-
-// @todo Yeah we probably should add that function that
-// also sets the content-type at the same time...
-
-To check if a response body has already been set:
-
-[source,erlang]
-cowboy_req:has_resp_body(Req).
-
-It returns `true` if the body was set and is non-empty,
-`false` otherwise.
-
-// @todo We probably should also have a function that
-// properly removes the response body, including any
-// content-* headers.
-
-The preset response body is only sent if the reply function
-used is `cowboy_req:reply/2` or `cowboy_req:reply/3`.
-
-=== Sending files
-
-Cowboy provides a shortcut for sending files. When
-using `cowboy_req:reply/4`, or when presetting the
-response header, you can give a `sendfile` tuple to
-Cowboy:
-
-[source,erlang]
-{sendfile, Offset, Length, Filename}
-
-Depending on the values for `Offset` or `Length`, the
-entire file may be sent, or just a part of it.
-
-The length is required even for sending the entire file.
-Cowboy sends it in the content-length header.
-
-To send a file while replying:
-
-[source,erlang]
-----
-Req = cowboy_req:reply(200, #{
-    <<"content-type">> => "image/png"
-}, {sendfile, 0, 12345, "path/to/logo.png"}, Req0).
-----
-
-// @todo An example of presetting a file would be useful,
-// but let's wait for the function that can set the
-// content-type at the same time.
-
-// @todo What about streaming many files? For example
-// it should be possible to build a tar file on the fly
-// while still using sendfile. Another example could be
-// proper support for multipart byte ranges. Yet another
-// example would be automatic concatenation of CSS or JS
-// files.
-
-=== Push
-
-The HTTP/2 protocol introduced the ability to push resources
-related to the one sent in the response. Cowboy provides two
-functions for that purpose: `cowboy_req:push/3,4`.
-
-Push is only available for HTTP/2. Cowboy will automatically
-ignore push requests if the protocol doesn't support it.
-
-The push function must be called before any of the reply
-functions. Doing otherwise will result in a crash.
-
-To push a resource, you need to provide the same information
-as a client performing a request would. This includes the
-HTTP method, the URI and any necessary request headers.
-
-Cowboy by default only requires you to give the path to
-the resource and the request headers. The rest of the URI
-is taken from the current request (excluding the query
-string, set to empty) and the method is GET by default.
-
-The following snippet pushes a CSS file that is linked to
-in the response:
-
-[source,erlang]
-----
-cowboy_req:push("/static/style.css", #{
-    <<"accept">> => <<"text/css">>
-}, Req0),
-Req = cowboy_req:reply(200, #{
-    <<"content-type">> => <<"text/html">>
-}, ["<html><head><title>My web page</title>",
-    "<link rel='stylesheet' type='text/css' href='/static/style.css'>",
-    "<body><p>Welcome to Erlang!</p></body></html>"], Req0).
-----
-
-To override the method, scheme, host, port or query string,
-simply pass in a fourth argument. The following snippet
-uses a different host name:
-
-[source,erlang]
-----
-cowboy_req:push("/static/style.css", #{
-    <<"accept">> => <<"text/css">>
-}, #{host => <<"cdn.example.org">>}, Req),
-----
-
-Pushed resources don't have to be files. As long as the push
-request is cacheable, safe and does not include a body, the
-resource can be pushed.
-
-Under the hood, Cowboy handles pushed requests the same as
-normal requests: a different process is created which will
-ultimately send a response to the client.

-<h1 class="lined-header"><span>Sending a response</span></h1>
-
-<p>The response must be sent using the Req object.</p>
-<p>Cowboy provides two different ways of sending responses: either directly or by streaming the body. Response headers and body may be set in advance. The response is sent as soon as one of the reply or stream reply function is called.</p>
-<p>Cowboy also provides a simplified interface for sending files. It can also send only specific parts of a file.</p>
-<p>While only one response is allowed for every request, HTTP/2 introduced a mechanism that allows the server to push additional resources related to the response. This chapter also describes how this feature works in Cowboy.</p>
-<h2 id="_reply">Reply</h2>
-<p>Cowboy provides three functions for sending the entire reply, depending on whether you need to set headers and body. In all cases, Cowboy will add any headers required by the protocol (for example the date header will always be sent).</p>
-<p>When you need to set only the status code, use <code>cowboy_req:reply/2</code>:</p>

-<p>You should always set the content-type header when the response has a body. There is however no need to set the content-length header; Cowboy does it automatically.</p>
-<p>The response body and the header values must be either a binary or an iolist. An iolist is a list containing binaries, characters, strings or other iolists. This allows you to build a response from different parts without having to do any concatenation:</p>

-<h2 id="_overriding_headers">Overriding headers</h2>
-<p>As Cowboy provides different ways of setting response headers and body, clashes may occur, so it&apos;s important to understand what happens when a header is set twice.</p>
-<p>Headers come from five different origins:</p>
-<ul><li>Protocol-specific headers (for example HTTP/1.1&apos;s connection header)
-</li>
-<li>Other required headers (for example the date header)
-</li>
-<li>Preset headers
-</li>
-<li>Headers given to the reply function
-</li>
-<li>Set-cookie headers
-</li>
-</ul>
-<p>Cowboy does not allow overriding protocol-specific headers.</p>
-<p>Set-cookie headers will always be appended at the end of the list of headers before sending the response.</p>
-<p>Headers given to the reply function will always override preset headers and required headers. If a header is found in two or three of these, then the one in the reply function is picked and the others are dropped.</p>
-<p>Similarly, preset headers will always override required headers.</p>
-<p>To illustrate, look at the following snippet. Cowboy by default sends the server header with the value &quot;Cowboy&quot;. We can override it:</p>

-<h2 id="_push">Push</h2>
-<p>The HTTP/2 protocol introduced the ability to push resources related to the one sent in the response. Cowboy provides two functions for that purpose: <code>cowboy_req:push/3,4</code>.</p>
-<p>Push is only available for HTTP/2. Cowboy will automatically ignore push requests if the protocol doesn&apos;t support it.</p>
-<p>The push function must be called before any of the reply functions. Doing otherwise will result in a crash.</p>
-<p>To push a resource, you need to provide the same information as a client performing a request would. This includes the HTTP method, the URI and any necessary request headers.</p>
-<p>Cowboy by default only requires you to give the path to the resource and the request headers. The rest of the URI is taken from the current request (excluding the query string, set to empty) and the method is GET by default.</p>

-== REST flowcharts
-
-This chapter will explain the REST handler state machine through
-a number of different diagrams.
-
-There are four main paths that requests may follow. One for the
-method OPTIONS; one for the methods GET and HEAD; one for the
-methods PUT, POST and PATCH; and one for the method DELETE.
-
-All paths start with the "Start" diagram, and all paths excluding
-the OPTIONS path go through the "Content negotiation" diagram
-and optionally the "Conditional requests" diagram if the resource
-exists.
-
-The red squares refer to another diagram. The light green squares
-indicate a response. Other squares may be either a callback or a
-question answered by Cowboy itself. Green arrows tend to indicate
-the default behavior if the callback is undefined.
-
-=== Start
-
-All requests start from here.
-
-image::rest_start.png[REST starting flowchart]
-
-A series of callbacks are called in succession to perform
-a general checkup of the service, the request line and
-request headers.
-
-The request body, if any, is not expected to have been
-received for any of these steps. It is only processed
-at the end of the "PUT, POST and PATCH methods" diagram,
-when all conditions have been met.
-
-The `known_methods` and `allowed_methods` callbacks
-return a list of methods. Cowboy then checks if the request
-method is in the list, and stops otherwise.
-
-The `is_authorized` callback may be used to check that
-access to the resource is authorized. Authentication
-may also be performed as needed. When authorization is
-denied, the return value from the callback must include
-a challenge applicable to the requested resource, which
-will be sent back to the client in the www-authenticate
-header.
-
-This diagram is immediately followed by either the
-"OPTIONS method" diagram when the request method is
-OPTIONS, or the "Content negotiation" diagram otherwise.
-
-=== OPTIONS method
-
-This diagram only applies to OPTIONS requests.
-
-image::rest_options.png[REST OPTIONS method flowchart]
-
-The `options` callback may be used to add information
-about the resource, such as media types or languages
-provided; allowed methods; any extra information. A
-response body may also be set, although clients should
-not be expected to read it.
-
-If the `options` callback is not defined, Cowboy will
-send a response containing the list of allowed methods
-by default.
-
-=== Content negotiation
-
-This diagram applies to all request methods other than
-OPTIONS. It is executed right after the "Start" diagram
-is completed.
-
-image::rest_conneg.png[REST content negotiation flowchart]
-
-The purpose of these steps is to determine an appropriate
-representation to be sent back to the client.
-
-The request may contain any of the accept header; the
-accept-language header; or the accept-charset header.
-When present, Cowboy will parse the headers and then
-call the corresponding callback to obtain the list
-of provided content-type, language or charset for this
-resource. It then automatically select the best match
-based on the request.
-
-If a callback is not defined, Cowboy will select the
-content-type, language or charset that the client
-prefers.
-
-The `content_types_provided` also returns the name of
-a callback for every content-type it accepts. This
-callback will only be called at the end of the
-"GET and HEAD methods" diagram, when all conditions
-have been met.
-
-The selected content-type, language and charset are
-saved as meta values in the Req object. You *should*
-use the appropriate representation if you set a
-response body manually (alongside an error code,
-for example).
-
-This diagram is immediately followed by
-the "GET and HEAD methods" diagram,
-the "PUT, POST and PATCH methods" diagram,
-or the "DELETE method" diagram, depending on the
-method.
-
-=== GET and HEAD methods
-
-This diagram only applies to GET and HEAD requests.
-
-For a description of the `cond` step, please see
-the "Conditional requests" diagram.
-
-image::rest_get_head.png[REST GET/HEAD methods flowchart]
-
-When the resource exists, and the conditional steps
-succeed, the resource can be retrieved.
-
-Cowboy prepares the response by first retrieving
-metadata about the representation, then by calling
-the `ProvideResource` callback. This is the callback
-you defined for each content-types you returned from
-`content_types_provided`. This callback returns the body
-that will be sent back to the client, or a fun if the
-body must be streamed.
-
-When the resource does not exist, Cowboy will figure out
-whether the resource existed previously, and if so whether
-it was moved elsewhere in order to redirect the client to
-the new URI.
-
-The `moved_permanently` and `moved_temporarily` callbacks
-must return the new location of the resource if it was in
-fact moved.
-
-=== PUT, POST and PATCH methods
-
-This diagram only applies to PUT, POST and PATCH requests.
-
-For a description of the `cond` step, please see
-the "Conditional requests" diagram.
-
-image::rest_put_post_patch.png[REST PUT/POST/PATCH methods flowchart]
-
-When the resource exists, first the conditional steps
-are executed. When that succeeds, and the method is PUT,
-Cowboy will call the `is_conflict` callback. This function
-can be used to prevent potential race conditions, by locking
-the resource for example.
-
-Then all three methods reach the `content_types_accepted`
-step that we will describe in a few paragraphs.
-
-When the resource does not exist, and the method is PUT,
-Cowboy will check for conflicts and then move on to the
-`content_types_accepted` step. For other methods, Cowboy
-will figure out whether the resource existed previously,
-and if so whether it was moved elsewhere. If the resource
-is truly non-existent, the method is POST and the call
-for `allow_missing_post` returns `true`, then Cowboy will
-move on to the `content_types_accepted` step. Otherwise
-the request processing ends there.
-
-The `moved_permanently` and `moved_temporarily` callbacks
-must return the new location of the resource if it was in
-fact moved.
-
-The `content_types_accepted` returns a list of
-content-types it accepts, but also the name of a callback
-for each of them. Cowboy will select the appropriate
-callback for processing the request body and call it.
-
-This callback may return one of three different return
-values.
-
-If an error occurred while processing the request body,
-it must return `false` and Cowboy will send an
-appropriate error response.
-
-If the method is POST, then you may return `true` with
-an URI of where the resource has been created. This is
-especially useful for writing handlers for collections.
-
-Otherwise, return `true` to indicate success. Cowboy
-will select the appropriate response to be sent depending
-on whether a resource has been created, rather than
-modified, and on the availability of a location header
-or a body in the response.
-
-=== DELETE method
-
-This diagram only applies to DELETE requests.
-
-For a description of the `cond` step, please see
-the "Conditional requests" diagram.
-
-image::rest_delete.png[REST DELETE method flowchart]
-
-When the resource exists, and the conditional steps
-succeed, the resource can be deleted.
-
-Deleting the resource is a two steps process. First
-the callback `delete_resource` is executed. Use this
-callback to delete the resource.
-
-Because the resource may be cached, you must also
-delete all cached representations of this resource
-in the system. This operation may take a while though,
-so you may return before it finished.
-
-Cowboy will then call the `delete_completed` callback.
-If you know that the resource has been completely
-deleted from your system, including from caches, then
-you can return `true`. If any doubts persist, return
-`false`. Cowboy will assume `true` by default.
-
-To finish, Cowboy checks if you set a response body,
-and depending on that, sends the appropriate response.
-
-When the resource does not exist, Cowboy will figure out
-whether the resource existed previously, and if so whether
-it was moved elsewhere in order to redirect the client to
-the new URI.
-
-The `moved_permanently` and `moved_temporarily` callbacks
-must return the new location of the resource if it was in
-fact moved.
-
-=== Conditional requests
-
-This diagram applies to all request methods other than
-OPTIONS. It is executed right after the `resource_exists`
-callback, when the resource exists.
-
-image::rest_cond.png[REST conditional requests flowchart]
-
-A request becomes conditional when it includes either of
-the if-match header; the if-unmodified-since header; the
-if-none-match header; or the if-modified-since header.
-
-If the condition fails, the request ends immediately
-without any retrieval or modification of the resource.
-
-The `generate_etag` and `last_modified` are called as
-needed. Cowboy will only call them once and then cache
-the results for subsequent use.

-[[rest_handlers]]
-== REST handlers
-
-REST is implemented in Cowboy as a sub protocol. The request
-is handled as a state machine with many optional callbacks
-describing the resource and modifying the machine's behavior.
-
-The REST handler is the recommended way to handle HTTP requests.
-
-=== Initialization
-
-First, the `init/2` callback is called. This callback is common
-to all handlers. To use REST for the current request, this function
-must return a `cowboy_rest` tuple.
-
-[source,erlang]
-----
-init(Req, State) ->
-    {cowboy_rest, Req, State}.
-----
-
-Cowboy will then switch to the REST protocol and start executing
-the state machine.
-
-After reaching the end of the flowchart, the `terminate/3` callback
-will be called if it is defined.
-
-=== Methods
-
-The REST component has code for handling the following HTTP methods:
-HEAD, GET, POST, PATCH, PUT, DELETE and OPTIONS.
-
-Other methods can be accepted, however they have no specific callback
-defined for them at this time.
-
-=== Callbacks
-
-All callbacks are optional. Some may become mandatory depending
-on what other defined callbacks return. The various flowcharts
-in the next chapter should be a useful to determine which callbacks
-you need.
-
-All callbacks take two arguments, the Req object and the State,
-and return a three-element tuple of the form `{Value, Req, State}`.
-
-All callbacks can also return `{stop, Req, State}` to stop execution
-of the request.
-
-The following table summarizes the callbacks and their default values.
-If the callback isn't defined, then the default value will be used.
-Please look at the flowcharts to find out the result of each return
-value.
-
-In the following table, "skip" means the callback is entirely skipped
-if it is undefined, moving directly to the next step. Similarly,
-"none" means there is no default value for this callback.
-
-[cols="<,^",options="header"]
-|===
-| Callback name          | Default value
-| allowed_methods        | `[<<"GET">>, <<"HEAD">>, <<"OPTIONS">>]`
-| allow_missing_post     | `true`
-| charsets_provided      | skip
-| content_types_accepted | none
-// @todo Space required for the time being: https://github.com/spf13/hugo/issues/2398
-| content_types_provided | `[{{ <<"text">>, <<"html">>, '*'}, to_html}]`
-| delete_completed       | `true`
-| delete_resource        | `false`
-| expires                | `undefined`
-| forbidden              | `false`
-| generate_etag          | `undefined`
-| is_authorized          | `true`
-| is_conflict            | `false`
-| known_methods          | `[<<"GET">>, <<"HEAD">>, <<"POST">>, <<"PUT">>, <<"PATCH">>, <<"DELETE">>, <<"OPTIONS">>]`
-| languages_provided     | skip
-| last_modified          | `undefined`
-| malformed_request      | `false`
-| moved_permanently      | `false`
-| moved_temporarily      | `false`
-| multiple_choices       | `false`
-| options                | `ok`
-| previously_existed     | `false`
-| resource_exists        | `true`
-| service_available      | `true`
-| uri_too_long           | `false`
-| valid_content_headers  | `true`
-| valid_entity_length    | `true`
-| variances              | `[]`
-|===
-
-As you can see, Cowboy tries to move on with the request whenever
-possible by using well thought out default values.
-
-In addition to these, there can be any number of user-defined
-callbacks that are specified through `content_types_accepted/2`
-and `content_types_provided/2`. They can take any name, however
-it is recommended to use a separate prefix for the callbacks of
-each function. For example, `from_html` and `to_html` indicate
-in the first case that we're accepting a resource given as HTML,
-and in the second case that we send one as HTML.
-
-=== Meta data
-
-Cowboy will set informative values to the Req object at various
-points of the execution. You can retrieve them by matching the
-Req object directly. The values are defined in the following table:
-
-[cols="<,<",options="header"]
-|===
-| Key        | Details
-| media_type | The content-type negotiated for the response entity.
-| language   | The language negotiated for the response entity.
-| charset    | The charset negotiated for the response entity.
-|===
-
-They can be used to send a proper body with the response to a
-request that used a method other than HEAD or GET.
-
-=== Response headers
-
-Cowboy will set response headers automatically over the execution
-of the REST code. They are listed in the following table.
-
-[cols="<,<",options="header"]
-|===
-| Header name      | Details
-| content-language | Language used in the response body
-| content-type     | Media type and charset of the response body
-| etag             | Etag of the resource
-| expires          | Expiration date of the resource
-| last-modified    | Last modification date for the resource
-| location         | Relative or absolute URI to the requested resource
-| vary             | List of headers that may change the representation of the resource

-<p>As you can see, Cowboy tries to move on with the request whenever possible by using well thought out default values.</p>
-<p>In addition to these, there can be any number of user-defined callbacks that are specified through <code>content_types_accepted/2</code> and <code>content_types_provided/2</code>. They can take any name, however it is recommended to use a separate prefix for the callbacks of each function. For example, <code>from_html</code> and <code>to_html</code> indicate in the first case that we&apos;re accepting a resource given as HTML, and in the second case that we send one as HTML.</p>
-<h2 id="_meta_data">Meta data</h2>
-<p>Cowboy will set informative values to the Req object at various points of the execution. You can retrieve them by matching the Req object directly. The values are defined in the following table:</p>
-<table rules="all" width="100%" frame="border"
-			cellspacing="0" cellpadding="4">
-<thead><tr><th>Key</th>
-<th>Details</th>
-</tr></thead><tbody><tr><td>media_type</td>
-<td>The content-type negotiated for the response entity.</td>
-</tr>
-<tr><td>language</td>
-<td>The language negotiated for the response entity.</td>
-</tr>
-<tr><td>charset</td>
-<td>The charset negotiated for the response entity.</td>
-</tr>
-</tbody></table>
-<p>They can be used to send a proper body with the response to a request that used a method other than HEAD or GET.</p>
-<h2 id="_response_headers">Response headers</h2>
-<p>Cowboy will set response headers automatically over the execution of the REST code. They are listed in the following table.</p>
-<table rules="all" width="100%" frame="border"
-			cellspacing="0" cellpadding="4">
-<thead><tr><th>Header name</th>
-<th>Details</th>
-</tr></thead><tbody><tr><td>content-language</td>
-<td>Language used in the response body</td>
-</tr>
-<tr><td>content-type</td>
-<td>Media type and charset of the response body</td>
-</tr>
-<tr><td>etag</td>
-<td>Etag of the resource</td>
-</tr>
-<tr><td>expires</td>
-<td>Expiration date of the resource</td>
-</tr>
-<tr><td>last-modified</td>
-<td>Last modification date for the resource</td>
-</tr>
-<tr><td>location</td>
-<td>Relative or absolute URI to the requested resource</td>

-== REST principles
-
-This chapter will attempt to define the concepts behind REST
-and explain what makes a service RESTful.
-
-REST is often confused with performing a distinct operation
-depending on the HTTP method, while using more than the GET
-and POST methods. That's highly misguided at best.
-
-We will first attempt to define REST and will look at what
-it means in the context of HTTP and the Web.
-For a more in-depth explanation of REST, you can read
-http://www.ics.uci.edu/~fielding/pubs/dissertation/top.htm[Roy T. Fielding's dissertation]
-as it does a great job explaining where it comes from and
-what it achieves.
-
-=== REST architecture
-
-REST is a *client-server* architecture. The client and the server
-both have a different set of concerns. The server stores and/or
-manipulates information and makes it available to the user in
-an efficient manner. The client takes that information and
-displays it to the user and/or uses it to perform subsequent
-requests for information. This separation of concerns allows both
-the client and the server to evolve independently as it only
-requires that the interface stays the same.
-
-REST is *stateless*. That means the communication between the
-client and the server always contains all the information needed
-to perform the request. There is no session state in the server,
-it is kept entirely on the client's side. If access to a resource
-requires authentication, then the client needs to authenticate
-itself with every request.
-
-REST is *cacheable*. The client, the server and any intermediary
-components can all cache resources in order to improve performance.
-
-REST provides a *uniform interface* between components. This
-simplifies the architecture, as all components follow the same
-rules to speak to one another. It also makes it easier to understand
-the interactions between the different components of the system.
-A number of constraints are required to achieve this. They are
-covered in the rest of the chapter.
-
-REST is a *layered system*. Individual components cannot see
-beyond the immediate layer with which they are interacting. This
-means that a client connecting to an intermediate component, like
-a proxy, has no knowledge of what lies beyond. This allows
-components to be independent and thus easily replaceable or
-extendable.
-
-REST optionally provides *code on demand*. Code may be downloaded
-to extend client functionality. This is optional however because
-the client may not be able to download or run this code, and so
-a REST component cannot rely on it being executed.
-
-=== Resources and resource identifiers
-
-A resource is an abstract concept. In a REST system, any information
-that can be named may be a resource. This includes documents, images,
-a collection of resources and any other information. Any information
-that can be the target of an hypertext link can be a resource.
-
-A resource is a conceptual mapping to a set of entities. The set of
-entities evolves over time; a resource doesn't. For example, a resource
-can map to "users who have logged in this past month" and another
-to "all users". At some point in time they may map to the same set of
-entities, because all users logged in this past month. But they are
-still different resources. Similarly, if nobody logged in recently,
-then the first resource may map to the empty set. This resource exists
-regardless of the information it maps to.
-
-Resources are identified by uniform resource identifiers, also known
-as URIs. Sometimes internationalized resource identifiers, or IRIs,
-may also be used, but these can be directly translated into a URI.
-
-In practice we will identify two kinds of resources. Individual
-resources map to a set of one element, for example "user Joe".
-Collection of resources map to a set of 0 to N elements,
-for example "all users".
-
-=== Resource representations
-
-The representation of a resource is a sequence of bytes associated
-with metadata.
-
-The metadata comes as a list of key-value pairs, where the name
-corresponds to a standard that defines the value's structure and
-semantics. With HTTP, the metadata comes in the form of request
-or response headers. The headers' structure and semantics are well
-defined in the HTTP standard. Metadata includes representation
-metadata, resource metadata and control data.
-
-The representation metadata gives information about the
-representation, such as its media type, the date of last
-modification, or even a checksum.
-
-Resource metadata could be link to related resources or
-information about additional representations of the resource.
-
-Control data allows parameterizing the request or response.
-For example, we may only want the representation returned if
-it is more recent than the one we have in cache. Similarly,
-we may want to instruct the client about how it should cache
-the representation. This isn't restricted to caching. We may,
-for example, want to store a new representation of a resource
-only if it wasn't modified since we first retrieved it.
-
-The data format of a representation is also known as the media
-type. Some media types are intended for direct rendering to the
-user, while others are intended for automated processing. The
-media type is a key component of the REST architecture.
-
-=== Self-descriptive messages
-
-Messages must be self-descriptive. That means that the data
-format of a representation must always come with its media
-type (and similarly requesting a resource involves choosing
-the media type of the representation returned). If you are
-sending HTML, then you must say it is HTML by sending the
-media type with the representation. In HTTP this is done
-using the content-type header.
-
-The media type is often an IANA registered media type, like
-`text/html` or `image/png`, but does not need to be. Exactly
-two things are important for respecting this constraint: that
-the media type is well specified, and that the sender and
-recipient agree about what the media type refers to.
-
-This means that you can create your own media types, like
-`application/x-mine`, and that as long as you write the
-specifications for it and that both endpoints agree about
-it then the constraint is respected.
-
-=== Hypermedia as the engine of application state
-
-The last constraint is generally where services that claim
-to be RESTful fail. Interactions with a server must be
-entirely driven by hypermedia. The client does not need
-any prior knowledge of the service in order to use it,
-other than an entry point and of course basic understanding
-of the media type of the representations, at the very least
-enough to find and identify hyperlinks and link relations.
-
-To give a simple example, if your service only works with
-the `application/json` media type then this constraint
-cannot be respected (as there are no concept of links in
-JSON) and thus your service isn't RESTful. This is the case
-for the majority of self-proclaimed REST services.
-
-On the other hand if you create a JSON based media type
-that has a concept of links and link relations, then
-your service might be RESTful.
-
-Respecting this constraint means that the entirety of the
-service becomes self-discoverable, not only the resources
-in it, but also the operations you can perform on it. This
-makes clients very thin as there is no need to implement
-anything specific to the service to operate on it.

-<p>REST is <strong>stateless</strong>. That means the communication between the client and the server always contains all the information needed to perform the request. There is no session state in the server, it is kept entirely on the client&apos;s side. If access to a resource requires authentication, then the client needs to authenticate itself with every request.</p>
-<p>REST is <strong>cacheable</strong>. The client, the server and any intermediary components can all cache resources in order to improve performance.</p>
-<p>REST provides a <strong>uniform interface</strong> between components. This simplifies the architecture, as all components follow the same rules to speak to one another. It also makes it easier to understand the interactions between the different components of the system. A number of constraints are required to achieve this. They are covered in the rest of the chapter.</p>
-<p>REST is a <strong>layered system</strong>. Individual components cannot see beyond the immediate layer with which they are interacting. This means that a client connecting to an intermediate component, like a proxy, has no knowledge of what lies beyond. This allows components to be independent and thus easily replaceable or extendable.</p>
-<p>REST optionally provides <strong>code on demand</strong>. Code may be downloaded to extend client functionality. This is optional however because the client may not be able to download or run this code, and so a REST component cannot rely on it being executed.</p>
-<h2 id="_resources_and_resource_identifiers">Resources and resource identifiers</h2>
-<p>A resource is an abstract concept. In a REST system, any information that can be named may be a resource. This includes documents, images, a collection of resources and any other information. Any information that can be the target of an hypertext link can be a resource.</p>
-<p>A resource is a conceptual mapping to a set of entities. The set of entities evolves over time; a resource doesn&apos;t. For example, a resource can map to &quot;users who have logged in this past month&quot; and another to &quot;all users&quot;. At some point in time they may map to the same set of entities, because all users logged in this past month. But they are still different resources. Similarly, if nobody logged in recently, then the first resource may map to the empty set. This resource exists regardless of the information it maps to.</p>
-<p>Resources are identified by uniform resource identifiers, also known as URIs. Sometimes internationalized resource identifiers, or IRIs, may also be used, but these can be directly translated into a URI.</p>
-<p>In practice we will identify two kinds of resources. Individual resources map to a set of one element, for example &quot;user Joe&quot;. Collection of resources map to a set of 0 to N elements, for example &quot;all users&quot;.</p>
-<h2 id="_resource_representations">Resource representations</h2>
-<p>The representation of a resource is a sequence of bytes associated with metadata.</p>
-<p>The metadata comes as a list of key-value pairs, where the name corresponds to a standard that defines the value&apos;s structure and semantics. With HTTP, the metadata comes in the form of request or response headers. The headers&apos; structure and semantics are well defined in the HTTP standard. Metadata includes representation metadata, resource metadata and control data.</p>
-<p>The representation metadata gives information about the representation, such as its media type, the date of last modification, or even a checksum.</p>
-<p>Resource metadata could be link to related resources or information about additional representations of the resource.</p>
-<p>Control data allows parameterizing the request or response. For example, we may only want the representation returned if it is more recent than the one we have in cache. Similarly, we may want to instruct the client about how it should cache the representation. This isn&apos;t restricted to caching. We may, for example, want to store a new representation of a resource only if it wasn&apos;t modified since we first retrieved it.</p>
-<p>The data format of a representation is also known as the media type. Some media types are intended for direct rendering to the user, while others are intended for automated processing. The media type is a key component of the REST architecture.</p>
-<h2 id="_self_descriptive_messages">Self-descriptive messages</h2>
-<p>Messages must be self-descriptive. That means that the data format of a representation must always come with its media type (and similarly requesting a resource involves choosing the media type of the representation returned). If you are sending HTML, then you must say it is HTML by sending the media type with the representation. In HTTP this is done using the content-type header.</p>
-<p>The media type is often an IANA registered media type, like <code>text/html</code> or <code>image/png</code>, but does not need to be. Exactly two things are important for respecting this constraint: that the media type is well specified, and that the sender and recipient agree about what the media type refers to.</p>
-<p>This means that you can create your own media types, like <code>application/x-mine</code>, and that as long as you write the specifications for it and that both endpoints agree about it then the constraint is respected.</p>
-<h2 id="_hypermedia_as_the_engine_of_application_state">Hypermedia as the engine of application state</h2>
-<p>The last constraint is generally where services that claim to be RESTful fail. Interactions with a server must be entirely driven by hypermedia. The client does not need any prior knowledge of the service in order to use it, other than an entry point and of course basic understanding of the media type of the representations, at the very least enough to find and identify hyperlinks and link relations.</p>
-<p>To give a simple example, if your service only works with the <code>application/json</code> media type then this constraint cannot be respected (as there are no concept of links in JSON) and thus your service isn&apos;t RESTful. This is the case for the majority of self-proclaimed REST services.</p>
-<p>On the other hand if you create a JSON based media type that has a concept of links and link relations, then your service might be RESTful.</p>
-<p>Respecting this constraint means that the entirety of the service becomes self-discoverable, not only the resources in it, but also the operations you can perform on it. This makes clients very thin as there is no need to implement anything specific to the service to operate on it.</p>

-[[routing]]
-== Routing
-
-Cowboy does nothing by default.
-
-To make Cowboy useful, you need to map URIs to Erlang modules that will
-handle the requests. This is called routing.
-
-When Cowboy receives a request, it tries to match the requested host and
-path to the configured routes. When there's a match, the route's
-associated handler is executed.
-
-Routes need to be compiled before they can be used by Cowboy.
-The result of the compilation is the dispatch rules.
-
-=== Syntax
-
-The general structure for the routes is defined as follow.
-
-[source,erlang]
-Routes = [Host1, Host2, ... HostN].
-
-Each host contains matching rules for the host along with optional
-constraints, and a list of routes for the path component.
-
-[source,erlang]
-Host1 = {HostMatch, PathsList}.
-Host2 = {HostMatch, Constraints, PathsList}.
-
-The list of routes for the path component is defined similar to the
-list of hosts.
-
-[source,erlang]
-PathsList = [Path1, Path2, ... PathN].
-
-Finally, each path contains matching rules for the path along with
-optional constraints, and gives us the handler module to be used
-along with its initial state.
-
-[source,erlang]
-Path1 = {PathMatch, Handler, InitialState}.
-Path2 = {PathMatch, Constraints, Handler, InitialState}.
-
-Continue reading to learn more about the match syntax and the optional
-constraints.
-
-=== Match syntax
-
-The match syntax is used to associate host names and paths with their
-respective handlers.
-
-The match syntax is the same for host and path with a few subtleties.
-Indeed, the segments separator is different, and the host is matched
-starting from the last segment going to the first. All examples will
-feature both host and path match rules and explain the differences
-when encountered.
-
-Excluding special values that we will explain at the end of this section,
-the simplest match value is a host or a path. It can be given as either
-a `string()` or a `binary()`.
-
-[source,erlang]
-----
-PathMatch1 = "/".
-PathMatch2 = "/path/to/resource".
-
-HostMatch1 = "cowboy.example.org".
-----
-
-As you can see, all paths defined this way must start with a slash
-character. Note that these two paths are identical as far as routing
-is concerned.
-
-[source,erlang]
-PathMatch2 = "/path/to/resource".
-PathMatch3 = "/path/to/resource/".
-
-Hosts with and without a trailing dot are equivalent for routing.
-Similarly, hosts with and without a leading dot are also equivalent.
-
-[source,erlang]
-HostMatch1 = "cowboy.example.org".
-HostMatch2 = "cowboy.example.org.".
-HostMatch3 = ".cowboy.example.org".
-
-It is possible to extract segments of the host and path and to store
-the values in the `Req` object for later use. We call these kind of
-values bindings.
-
-The syntax for bindings is very simple. A segment that begins with
-the `:` character means that what follows until the end of the segment
-is the name of the binding in which the segment value will be stored.
-
-[source,erlang]
-PathMatch = "/hats/:name/prices".
-HostMatch = ":subdomain.example.org".
-
-If these two end up matching when routing, you will end up with two
-bindings defined, `subdomain` and `name`, each containing the
-segment value where they were defined. For example, the URL
-`http://test.example.org/hats/wild_cowboy_legendary/prices` will
-result in having the value `test` bound to the name `subdomain`
-and the value `wild_cowboy_legendary` bound to the name `name`.
-They can later be retrieved using `cowboy_req:binding/{2,3}`. The
-binding name must be given as an atom.
-
-There is a special binding name you can use to mimic the underscore
-variable in Erlang. Any match against the `_` binding will succeed
-but the data will be discarded. This is especially useful for
-matching against many domain names in one go.
-
-[source,erlang]
-HostMatch = "ninenines.:_".
-
-Similarly, it is possible to have optional segments. Anything
-between brackets is optional.
-
-[source,erlang]
-PathMatch = "/hats/[page/:number]".
-HostMatch = "[www.]ninenines.eu".
-
-You can also have imbricated optional segments.
-
-[source,erlang]
-PathMatch = "/hats/[page/[:number]]".
-
-You can retrieve the rest of the host or path using `[...]`.
-In the case of hosts it will match anything before, in the case
-of paths anything after the previously matched segments. It is
-a special case of optional segments, in that it can have
-zero, one or many segments. You can then find the segments using
-`cowboy_req:host_info/1` and `cowboy_req:path_info/1` respectively.
-They will be represented as a list of segments.
-
-[source,erlang]
-PathMatch = "/hats/[...]".
-HostMatch = "[...]ninenines.eu".
-
-If a binding appears twice in the routing rules, then the match
-will succeed only if they share the same value. This copies the
-Erlang pattern matching behavior.
-
-[source,erlang]
-PathMatch = "/hats/:name/:name".
-
-This is also true when an optional segment is present. In this
-case the two values must be identical only if the segment is
-available.
-
-[source,erlang]
-PathMatch = "/hats/:name/[:name]".
-
-If a binding is defined in both the host and path, then they must
-also share the same value.
-
-[source,erlang]
-PathMatch = "/:user/[...]".
-HostMatch = ":user.github.com".
-
-Finally, there are two special match values that can be used. The
-first is the atom `'_'` which will match any host or path.
-
-[source,erlang]
-PathMatch = '_'.
-HostMatch = '_'.
-
-The second is the special host match `"*"` which will match the
-wildcard path, generally used alongside the `OPTIONS` method.
-
-[source,erlang]
-HostMatch = "*".
-
-=== Constraints
-
-After the matching has completed, the resulting bindings can be tested
-against a set of constraints. Constraints are only tested when the
-binding is defined. They run in the order you defined them. The match
-will succeed only if they all succeed. If the match fails, then Cowboy
-tries the next route in the list.
-
-The format used for constraints is the same as match functions in
-`cowboy_req`: they are provided as a list of fields which may have
-one or more constraints. While the router accepts the same format,
-it will skip fields with no constraints and will also ignore default
-values, if any.
-
-Read more about xref:constraints[constraints].
-
-=== Compilation
-
-The routes must be compiled before Cowboy can use them. The compilation
-step normalizes the routes to simplify the code and speed up the
-execution, but the routes are still looked up one by one in the end.
-Faster compilation strategies could be to compile the routes directly
-to Erlang code, but would require heavier dependencies.
-
-To compile routes, just call the appropriate function:
-
-[source,erlang]
-----
-Dispatch = cowboy_router:compile([
-    %% {HostMatch, list({PathMatch, Handler, InitialState})}
-    {'_', [{'_', my_handler, #{}}]}
-]),
-%% Name, NbAcceptors, TransOpts, ProtoOpts
-cowboy:start_clear(my_http_listener,
-    [{port, 8080}],
-    #{env => #{dispatch => Dispatch}}
-).
-----
-
-=== Live update
-
-You can use the `cowboy:set_env/3` function for updating the dispatch
-list used by routing. This will apply to all new connections accepted
-by the listener:
-
-[source,erlang]
-Dispatch = cowboy_router:compile(Routes),
-cowboy:set_env(my_http_listener, dispatch, Dispatch).
-
-Note that you need to compile the routes again before updating.

-
-<p>Cowboy does nothing by default.</p>
-<p>To make Cowboy useful, you need to map URIs to Erlang modules that will handle the requests. This is called routing.</p>
-<p>When Cowboy receives a request, it tries to match the requested host and path to the configured routes. When there&apos;s a match, the route&apos;s associated handler is executed.</p>
-<p>Routes need to be compiled before they can be used by Cowboy. The result of the compilation is the dispatch rules.</p>
-<h2 id="_syntax">Syntax</h2>
-<p>The general structure for the routes is defined as follow.</p>

-<p>Continue reading to learn more about the match syntax and the optional constraints.</p>
-<h2 id="_match_syntax">Match syntax</h2>
-<p>The match syntax is used to associate host names and paths with their respective handlers.</p>
-<p>The match syntax is the same for host and path with a few subtleties. Indeed, the segments separator is different, and the host is matched starting from the last segment going to the first. All examples will feature both host and path match rules and explain the differences when encountered.</p>
-<p>Excluding special values that we will explain at the end of this section, the simplest match value is a host or a path. It can be given as either a <code>string()</code> or a <code>binary()</code>.</p>

-<p>It is possible to extract segments of the host and path and to store the values in the <code>Req</code> object for later use. We call these kind of values bindings.</p>
-<p>The syntax for bindings is very simple. A segment that begins with the <code>:</code> character means that what follows until the end of the segment is the name of the binding in which the segment value will be stored.</p>

-</div></div>
-<p>If these two end up matching when routing, you will end up with two bindings defined, <code>subdomain</code> and <code>name</code>, each containing the segment value where they were defined. For example, the URL <code>http://test.example.org/hats/wild_cowboy_legendary/prices</code> will result in having the value <code>test</code> bound to the name <code>subdomain</code> and the value <code>wild_cowboy_legendary</code> bound to the name <code>name</code>. They can later be retrieved using <code>cowboy_req:binding/{2,3}</code>. The binding name must be given as an atom.</p>
-<p>There is a special binding name you can use to mimic the underscore variable in Erlang. Any match against the <code>_</code> binding will succeed but the data will be discarded. This is especially useful for matching against many domain names in one go.</p>

-<p>You can retrieve the rest of the host or path using <code>[...]</code>. In the case of hosts it will match anything before, in the case of paths anything after the previously matched segments. It is a special case of optional segments, in that it can have zero, one or many segments. You can then find the segments using <code>cowboy_req:host_info/1</code> and <code>cowboy_req:path_info/1</code> respectively. They will be represented as a list of segments.</p>

-<p>If a binding appears twice in the routing rules, then the match will succeed only if they share the same value. This copies the Erlang pattern matching behavior.</p>

-<p>Finally, there are two special match values that can be used. The first is the atom <code>&apos;_&apos;</code> which will match any host or path.</p>

-<h2 id="_constraints">Constraints</h2>
-<p>After the matching has completed, the resulting bindings can be tested against a set of constraints. Constraints are only tested when the binding is defined. They run in the order you defined them. The match will succeed only if they all succeed. If the match fails, then Cowboy tries the next route in the list.</p>
-<p>The format used for constraints is the same as match functions in <code>cowboy_req</code>: they are provided as a list of fields which may have one or more constraints. While the router accepts the same format, it will skip fields with no constraints and will also ignore default values, if any.</p>
-<p>Read more about <a href="../constraints">constraints</a>.</p>
-<h2 id="_compilation">Compilation</h2>
-<p>The routes must be compiled before Cowboy can use them. The compilation step normalizes the routes to simplify the code and speed up the execution, but the routes are still looked up one by one in the end. Faster compilation strategies could be to compile the routes directly to Erlang code, but would require heavier dependencies.</p>
-<p>To compile routes, just call the appropriate function:</p>

-[[static_files]]
-== Static files
-
-Cowboy comes with a ready to use handler for serving static
-files. It is provided as a convenience for serving files
-during development.
-
-For systems in production, consider using one of the many
-Content Distribution Network (CDN) available on the market,
-as they are the best solution for serving files.
-
-The static handler can serve either one file or all files
-from a given directory. The etag generation and mime types
-can be configured.
-
-=== Serve one file
-
-You can use the static handler to serve one specific file
-from an application's private directory. This is particularly
-useful to serve an 'index.html' file when the client requests
-the `/` path, for example. The path configured is relative
-to the given application's private directory.
-
-The following rule will serve the file 'static/index.html'
-from the application `my_app`'s priv directory whenever the
-path `/` is accessed:
-
-[source,erlang]
-{"/", cowboy_static, {priv_file, my_app, "static/index.html"}}
-
-You can also specify the absolute path to a file, or the
-path to the file relative to the current directory:
-
-[source,erlang]
-{"/", cowboy_static, {file, "/var/www/index.html"}}
-
-=== Serve all files from a directory
-
-You can also use the static handler to serve all files that
-can be found in the configured directory. The handler will
-use the `path_info` information to resolve the file location,
-which means that your route must end with a `[...]` pattern
-for it to work. All files are served, including the ones that
-may be found in subfolders.
-
-You can specify the directory relative to an application's
-private directory.
-
-The following rule will serve any file found in the application
-`my_app`'s priv directory inside the `static/assets` folder
-whenever the requested path begins with `/assets/`:
-
-[source,erlang]
-{"/assets/[...]", cowboy_static, {priv_dir, my_app, "static/assets"}}
-
-You can also specify the absolute path to the directory or
-set it relative to the current directory:
-
-[source,erlang]
-{"/assets/[...]", cowboy_static, {dir, "/var/www/assets"}}
-
-=== Customize the mimetype detection
-
-By default, Cowboy will attempt to recognize the mimetype
-of your static files by looking at the extension.
-
-You can override the function that figures out the mimetype
-of the static files. It can be useful when Cowboy is missing
-a mimetype you need to handle, or when you want to reduce
-the list to make lookups faster. You can also give a
-hard-coded mimetype that will be used unconditionally.
-
-Cowboy comes with two functions built-in. The default
-function only handles common file types used when building
-Web applications. The other function is an extensive list
-of hundreds of mimetypes that should cover almost any need
-you may have. You can of course create your own function.
-
-To use the default function, you should not have to configure
-anything, as it is the default. If you insist, though, the
-following will do the job:
-
-[source,erlang]
-----
-{"/assets/[...]", cowboy_static, {priv_dir, my_app, "static/assets",
-    [{mimetypes, cow_mimetypes, web}]}}
-----
-
-As you can see, there is an optional field that may contain
-a list of less used options, like mimetypes or etag. All option
-types have this optional field.
-
-To use the function that will detect almost any mimetype,
-the following configuration will do:
-
-[source,erlang]
-----
-{"/assets/[...]", cowboy_static, {priv_dir, my_app, "static/assets",
-    [{mimetypes, cow_mimetypes, all}]}}
-----
-
-You probably noticed the pattern by now. The configuration
-expects a module and a function name, so you can use any
-of your own functions instead:
-
-[source,erlang]
-----
-{"/assets/[...]", cowboy_static, {priv_dir, my_app, "static/assets",
-    [{mimetypes, Module, Function}]}}
-----
-
-The function that performs the mimetype detection receives
-a single argument that is the path to the file on disk. It
-is recommended to return the mimetype in tuple form, although
-a binary string is also allowed (but will require extra
-processing). If the function can't figure out the mimetype,
-then it should return `{<<"application">>, <<"octet-stream">>, []}`.
-
-When the static handler fails to find the extension,
-it will send the file as `application/octet-stream`.
-A browser receiving such file will attempt to download it
-directly to disk.
-
-Finally, the mimetype can be hard-coded for all files.
-This is especially useful in combination with the `file`
-and `priv_file` options as it avoids needless computation:
-
-[source,erlang]
-----
-{"/", cowboy_static, {priv_file, my_app, "static/index.html",
-    [{mimetypes, {<<"text">>, <<"html">>, []}}]}}
-----
-
-=== Generate an etag
-
-By default, the static handler will generate an etag header
-value based on the size and modified time. This solution
-can not be applied to all systems though. It would perform
-rather poorly over a cluster of nodes, for example, as the
-file metadata will vary from server to server, giving a
-different etag on each server.
-
-You can however change the way the etag is calculated:
-
-[source,erlang]
-----
-{"/assets/[...]", cowboy_static, {priv_dir, my_app, "static/assets",
-    [{etag, Module, Function}]}}
-----
-
-This function will receive three arguments: the path to the
-file on disk, the size of the file and the last modification
-time. In a distributed setup, you would typically use the
-file path to retrieve an etag value that is identical across
-all your servers.
-
-You can also completely disable etag handling:
-
-[source,erlang]
-----
-{"/assets/[...]", cowboy_static, {priv_dir, my_app, "static/assets",
-    [{etag, false}]}}

-
-<p>Cowboy comes with a ready to use handler for serving static files. It is provided as a convenience for serving files during development.</p>
-<p>For systems in production, consider using one of the many Content Distribution Network (CDN) available on the market, as they are the best solution for serving files.</p>
-<p>The static handler can serve either one file or all files from a given directory. The etag generation and mime types can be configured.</p>
-<h2 id="_serve_one_file">Serve one file</h2>
-<p>You can use the static handler to serve one specific file from an application&apos;s private directory. This is particularly useful to serve an <em>index.html</em> file when the client requests the <code>/</code> path, for example. The path configured is relative to the given application&apos;s private directory.</p>
-<p>The following rule will serve the file <em>static/index.html</em> from the application <code>my_app</code>&apos;s priv directory whenever the path <code>/</code> is accessed:</p>

-<h2 id="_serve_all_files_from_a_directory">Serve all files from a directory</h2>
-<p>You can also use the static handler to serve all files that can be found in the configured directory.

All files are served, including the ones that may be found in subfolders.</p>
-<p>You can specify the directory relative to an application&apos;s private directory.</p>
-<p>The following rule will serve any file found in the application <code>my_app</code>&apos;s priv directory inside the <code>static/assets</code> folder whenever the requested path begins with <code>/assets/</code>:</p>

-<h2 id="_customize_the_mimetype_detection">Customize the mimetype detection</h2>
-<p>By default, Cowboy will attempt to recognize the mimetype of your static files by looking at the extension.</p>
-<p>You can override the function that figures out the mimetype of the static files. It can be useful when Cowboy is missing a mimetype you need to handle, or when you want to reduce the list to make lookups faster. You can also give a hard-coded mimetype that will be used unconditionally.</p>
-<p>Cowboy comes with two functions built-in. The default function only handles common file types used when building Web applications. The other function is an extensive list of hundreds of mimetypes that should cover almost any need you may have. You can of course create your own function.</p>
-<p>To use the default function, you should not have to configure anything, as it is the default. If you insist, though, the following will do the job:</p>
-<div class="listingblock"><div class="content"><!-- Generator: GNU source-highlight 3.1.8

-</div></div>
-<p>As you can see, there is an optional field that may contain a list of less used options, like mimetypes or etag. All option types have this optional field.</p>
-<p>To use the function that will detect almost any mimetype, the following configuration will do:</p>
-<div class="listingblock"><div class="content"><!-- Generator: GNU source-highlight 3.1.8

-    [{<font color="#FF6600">mimetypes</font>, <font color="#FF6600">cow_mimetypes</font>, <font color="#FF6600">all</font>}]}}</tt></pre>
-</div></div>
-<p>You probably noticed the pattern by now. The configuration expects a module and a function name, so you can use any of your own functions instead:</p>

-</div></div>
-<p>The function that performs the mimetype detection receives a single argument that is the path to the file on disk. It is recommended to return the mimetype in tuple form, although a binary string is also allowed (but will require extra processing). If the function can&apos;t figure out the mimetype, then it should return <code>{&lt;&lt;&quot;application&quot;&gt;&gt;, &lt;&lt;&quot;octet-stream&quot;&gt;&gt;, []}</code>.</p>
-<p>When the static handler fails to find the extension, it will send the file as <code>application/octet-stream</code>. A browser receiving such file will attempt to download it directly to disk.</p>
-<p>Finally, the mimetype can be hard-coded for all files. This is especially useful in combination with the <code>file</code> and <code>priv_file</code> options as it avoids needless computation:</p>

-<h2 id="_generate_an_etag">Generate an etag</h2>
-<p>By default, the static handler will generate an etag header value based on the size and modified time. This solution can not be applied to all systems though.

-<p>You can however change the way the etag is calculated:</p>

-[[streams]]
-== Streams
-
-A stream is the set of messages that form an HTTP
-request/response pair.
-
-The term stream comes from HTTP/2. In Cowboy, it is
-also used when talking about HTTP/1.1 or HTTP/1.0.
-It should not be confused with streaming the request
-or response body.
-
-All versions of HTTP allow clients to initiate
-streams. HTTP/2 is the only one also allowing servers,
-through its server push feature. Both client and
-server-initiated streams go through the same process
-in Cowboy.
-
-=== Stream handlers
-
-Stream handlers must implement five different callbacks.
-Four of them are directly related; one is special.
-
-All callbacks receives the stream ID as first argument.
-
-Most of them can return a list of commands to be executed
-by Cowboy. When callbacks are chained, it is possible to
-intercept and modify these commands. This can be useful
-for modifying responses for example.
-
-The `init/3` callback is invoked when a new request
-comes in. It receives the Req object and the protocol options
-for this listener.
-
-The `data/4` callback is invoked when data from the request
-body is received. It receives both this data and a flag
-indicating whether more is to be expected.
-
-The `info/3` callback is invoked when an Erlang message is
-received for this stream. They will typically be messages
-sent by the request process.
-
-Finally the `terminate/3` callback is invoked with the
-terminate reason for the stream. The return value is ignored.
-Note that as with all terminate callbacks in Erlang, there
-is no strong guarantee that it will be called.
-
-The special callback `early_error/5` is called when an error
-occurs before the request headers were fully received and
-Cowboy is sending a response. It receives the partial Req
-object, the error reason, the protocol options and the response
-Cowboy will send. This response must be returned, possibly
-modified.
-
-=== Built-in handlers
-
-Cowboy comes with two handlers.
-
-`cowboy_stream_h` is the default stream handler.
-It is the core of much of the functionality of Cowboy.
-All chains of stream handlers should call it last.
-
-`cowboy_compress_h` will automatically compress
-responses when possible. It is not enabled by default.
-It is a good example for writing your own handlers
-that will modify responses.

-<h1 class="lined-header"><span>Streams</span></h1>
-
-<p>A stream is the set of messages that form an HTTP request/response pair.</p>
-<p>The term stream comes from HTTP/2. In Cowboy, it is also used when talking about HTTP/1.1 or HTTP/1.0. It should not be confused with streaming the request or response body.</p>
-<p>All versions of HTTP allow clients to initiate streams. HTTP/2 is the only one also allowing servers, through its server push feature. Both client and server-initiated streams go through the same process in Cowboy.</p>
-<h2 id="_stream_handlers">Stream handlers</h2>
-<p>Stream handlers must implement five different callbacks. Four of them are directly related; one is special.</p>
-<p>All callbacks receives the stream ID as first argument.</p>
-<p>Most of them can return a list of commands to be executed by Cowboy. When callbacks are chained, it is possible to intercept and modify these commands. This can be useful for modifying responses for example.</p>
-<p>The <code>init/3</code> callback is invoked when a new request comes in. It receives the Req object and the protocol options for this listener.</p>
-<p>The <code>data/4</code> callback is invoked when data from the request body is received. It receives both this data and a flag indicating whether more is to be expected.</p>
-<p>The <code>info/3</code> callback is invoked when an Erlang message is received for this stream. They will typically be messages sent by the request process.</p>
-<p>Finally the <code>terminate/3</code> callback is invoked with the terminate reason for the stream. The return value is ignored. Note that as with all terminate callbacks in Erlang, there is no strong guarantee that it will be called.</p>
-<p>The special callback <code>early_error/5</code> is called when an error occurs before the request headers were fully received and Cowboy is sending a response. It receives the partial Req object, the error reason, the protocol options and the response Cowboy will send. This response must be returned, possibly modified.</p>
-<h2 id="_built_in_handlers">Built-in handlers</h2>
-<p>Cowboy comes with two handlers.</p>
-<p><code>cowboy_stream_h</code> is the default stream handler. It is the core of much of the functionality of Cowboy. All chains of stream handlers should call it last.</p>
-<p><code>cowboy_compress_h</code> will automatically compress responses when possible. It is not enabled by default. It is a good example for writing your own handlers that will modify responses.</p>

-== Websocket handlers
-
-Websocket handlers provide an interface for upgrading HTTP/1.1
-connections to Websocket and sending or receiving frames on
-the Websocket connection.
-
-As Websocket connections are established through the HTTP/1.1
-upgrade mechanism, Websocket handlers need to be able to first
-receive the HTTP request for the upgrade, before switching to
-Websocket and taking over the connection. They can then receive
-or send Websocket frames, handle incoming Erlang messages or
-close the connection.
-
-=== Upgrade
-
-The `init/2` callback is called when the request is received.
-To establish a Websocket connection, you must switch to the
-`cowboy_websocket` module:
-
-[source,erlang]
-----
-init(Req, State) ->
-    {cowboy_websocket, Req, State}.
-----
-
-Cowboy will perform the Websocket handshake immediately. Note
-that the handshake will fail if the client did not request an
-upgrade to Websocket.
-
-The Req object becomes unavailable after this function returns.
-Any information required for proper execution of the Websocket
-handler must be saved in the state.
-
-=== Subprotocol
-
-The client may provide a list of Websocket subprotocols it
-supports in the sec-websocket-protocol header. The server *must*
-select one of them and send it back to the client or the
-handshake will fail.
-
-For example, a client could understand both STOMP and MQTT over
-Websocket, and provide the header:
-
-----
-sec-websocket-protocol: v12.stomp, mqtt
-----
-
-If the server only understands MQTT it can return:
-
-----
-sec-websocket-protocol: mqtt
-----
-
-This selection must be done in `init/2`. An example usage could
-be:
-
-[source,erlang]
-----
-init(Req, State) ->
-    case cowboy_req:parse_header(<<"sec-websocket-protocol">>, Req) of
-        undefined ->
-            {cowboy_websocket, Req, State};
-        Subprotocols ->
-            case lists:keymember(<<"mqtt">>, 1, Subprotocols) of
-                true ->
-                    Req2 = cowboy_req:set_resp_header(<<"sec-websocket-protocol">>,
-                        <<"mqtt">>, Req),
-                    {cowboy_websocket, Req2, State};
-                false ->
-                    {stop, Req, State}
-            end
-    end.
-----
-
-=== Post-upgrade initialization
-
-Cowboy has separate processes for handling the connection
-and requests. Because Websocket takes over the connection,
-the Websocket protocol handling occurs in a different
-process than the request handling.
-
-This is reflected in the different callbacks Websocket
-handlers have. The `init/2` callback is called from the
-temporary request process and the `websocket_` callbacks
-from the connection process.
-
-This means that some initialization cannot be done from
-`init/2`. Anything that would require the current pid,
-or be tied to the current pid, will not work as intended.
-The optional `websocket_init/1` can be used instead:
-
-[source,erlang]
-----
-websocket_init(State) ->
-    erlang:start_timer(1000, self(), <<"Hello!">>),
-    {ok, State}.
-----
-
-All Websocket callbacks share the same return values. This
-means that we can send frames to the client right after
-the upgrade:
-
-[source,erlang]
-----
-websocket_init(State) ->
-    {reply, {text, <<"Hello!">>}, State}.
-----
-
-=== Receiving frames
-
-Cowboy will call `websocket_handle/2` whenever a text, binary,
-ping or pong frame arrives from the client.
-
-The handler can handle or ignore the frames. It can also
-send frames back to the client or stop the connection.
-
-The following snippet echoes back any text frame received and
-ignores all others:
-
-[source,erlang]
-----
-websocket_handle(Frame = {text, _}, State) ->
-    {reply, Frame, State};
-websocket_handle(_Frame, State) ->
-    {ok, State}.
-----
-
-Note that ping and pong frames require no action from the
-handler as Cowboy will automatically reply to ping frames.
-They are provided for informative purposes only.
-
-=== Receiving Erlang messages
-
-Cowboy will call `websocket_info/2` whenever an Erlang message
-arrives.
-
-The handler can handle or ignore the messages. It can also
-send frames to the client or stop the connection.
-
-The following snippet forwards log messages to the client
-and ignores all others:
-
-[source,erlang]
-----
-websocket_info({log, Text}, State) ->
-    {reply, {text, Text}, State};
-websocket_info(_Info, State) ->
-    {ok, State}.
-----
-
-=== Sending frames
-
-// @todo This will be deprecated and eventually replaced with a
-// {Commands, State} interface that allows providing more
-// functionality easily.
-
-All `websocket_` callbacks share return values. They may
-send zero, one or many frames to the client.
-
-To send nothing, just return an ok tuple:
-
-[source,erlang]
-----
-websocket_info(_Info, State) ->
-    {ok, State}.
-----
-
-To send one frame, return a reply tuple with the frame to send:
-
-[source,erlang]
-----
-websocket_info(_Info, State) ->
-    {reply, {text, <<"Hello!">>}, State}.
-----
-
-You can send frames of any type: text, binary, ping, pong
-or close frames.
-
-To send many frames at once, return a reply tuple with the
-list of frames to send:
-
-[source,erlang]
-----
-websocket_info(_Info, State) ->
-    {reply, [
-        {text, "Hello"},
-        {text, <<"world!">>},
-        {binary, <<0:8000>>}
-    ], State}.
-----
-
-They are sent in the given order.
-
-=== Keeping the connection alive
-
-Cowboy will automatically respond to ping frames sent by
-the client. They are still forwarded to the handler for
-informative purposes, but no further action is required.
-
-Cowboy does not send ping frames itself. The handler can
-do it if required. A better solution in most cases is to
-let the client handle pings. Doing it from the handler
-would imply having an additional timer per connection and
-this can be a considerable cost for servers that need to
-handle large numbers of connections.
-
-Cowboy can be configured to close idle connections
-automatically. It is highly recommended to configure
-a timeout here, to avoid having processes linger longer
-than needed.
-
-The `init/2` callback can set the timeout to be used
-for the connection. For example, this would make Cowboy
-close connections idle for more than 30 seconds:
-
-[source,erlang]
-----
-init(Req, State) ->
-    {cowboy_websocket, Req, State, #{
-        idle_timeout => 30000}}.
-----
-
-This value cannot be changed once it is set. It defaults to
-`60000`.
-
-=== Saving memory
-
-The Websocket connection process can be set to hibernate
-after the callback returns.
-
-Simply add an `hibernate` field to the ok or reply tuples:
-
-[source,erlang]
-----
-websocket_init(State) ->
-    {ok, State, hibernate}.
-
-websocket_handle(_Frame, State) ->
-    {ok, State, hibernate}.
-
-websocket_info(_Info, State) ->
-    {reply, {text, <<"Hello!">>}, State, hibernate}.
-----
-
-It is highly recommended to write your handlers with
-hibernate enabled, as this allows to greatly reduce the
-memory usage. Do note however that an increase in the
-CPU usage or latency can be observed instead, in particular
-for the more busy connections.
-
-=== Closing the connection
-
-The connection can be closed at any time, either by telling
-Cowboy to stop it or by sending a close frame.
-
-To tell Cowboy to close the connection, use a stop tuple:
-
-[source,erlang]
-----
-websocket_info(_Info, State) ->
-    {stop, State}.
-----
-
-Sending a `close` frame will immediately initiate the closing
-of the Websocket connection. Note that when sending a list of
-frames that include a close frame, any frame found after the
-close frame will not be sent.

-<p>Cowboy has separate processes for handling the connection and requests. Because Websocket takes over the connection, the Websocket protocol handling occurs in a different process than the request handling.</p>
-<p>This is reflected in the different callbacks Websocket handlers have. The <code>init/2</code> callback is called from the temporary request process and the <code>websocket_</code> callbacks from the connection process.</p>
-<p>This means that some initialization cannot be done from <code>init/2</code>. Anything that would require the current pid, or be tied to the current pid, will not work as intended. The optional <code>websocket_init/1</code> can be used instead:</p>

-<p>Cowboy will automatically respond to ping frames sent by the client. They are still forwarded to the handler for informative purposes, but no further action is required.</p>
-<p>Cowboy does not send ping frames itself. The handler can do it if required. A better solution in most cases is to let the client handle pings. Doing it from the handler would imply having an additional timer per connection and this can be a considerable cost for servers that need to handle large numbers of connections.</p>
-<p>Cowboy can be configured to close idle connections automatically. It is highly recommended to configure a timeout here, to avoid having processes linger longer than needed.</p>
-<p>The <code>init/2</code> callback can set the timeout to be used for the connection. For example, this would make Cowboy close connections idle for more than 30 seconds:</p>

-== The Websocket protocol
-
-This chapter explains what Websocket is and why it is
-a vital component of soft realtime Web applications.
-
-=== Description
-
-Websocket is an extension to HTTP that emulates plain TCP
-connections between the client, typically a Web browser,
-and the server. It uses the HTTP Upgrade mechanism to
-establish the connection.
-
-Websocket connections are fully asynchronous, unlike
-HTTP/1.1 (synchronous) and HTTP/2 (asynchronous, but the
-server can only initiate streams in response to requests).
-With Websocket, the client and the server can both send
-frames at any time without any restriction. It is closer
-to TCP than any of the HTTP protocols.
-
-Websocket is an IETF standard. Cowboy supports the standard
-and all drafts that were previously implemented by browsers,
-excluding the initial flawed draft sometimes known as
-"version 0".
-
-=== Websocket vs HTTP/2
-
-For a few years Websocket was the only way to have a
-bidirectional asynchronous connection with the server.
-This changed when HTTP/2 was introduced. While HTTP/2
-requires the client to first perform a request before
-the server can push data, this is only a minor restriction
-as the client can do so just as it connects.
-
-Websocket was designed as a kind-of-TCP channel to a
-server. It only defines the framing and connection
-management and lets the developer implement a protocol
-on top of it. For example you could implement IRC over
-Websocket and use a Javascript IRC client to speak to
-the server.
-
-HTTP/2 on the other hand is just an improvement over
-the HTTP/1.1 connection and request/response mechanism.
-It has the same semantics as HTTP/1.1.
-
-If all you need is to access an HTTP API, then HTTP/2
-should be your first choice. On the other hand, if what
-you need is a different protocol, then you can use
-Websocket to implement it.
-
-=== Implementation
-
-Cowboy implements Websocket as a protocol upgrade. Once the
-upgrade is performed from the `init/2` callback, Cowboy
-switches to Websocket. Please consult the next chapter for
-more information on initiating and handling Websocket
-connections.
-
-The implementation of Websocket in Cowboy is validated using
-the Autobahn test suite, which is an extensive suite of tests
-covering all aspects of the protocol. Cowboy passes the
-suite with 100% success, including all optional tests.
-
-Cowboy's Websocket implementation also includes the
-permessage-deflate and x-webkit-deflate-frame compression
-extensions.
-
-Cowboy will automatically use compression when the
-`compress` option is returned from the `init/2` function.

-<h1 class="lined-header"><span>The Websocket protocol</span></h1>
-
-<p>This chapter explains what Websocket is and why it is a vital component of soft realtime Web applications.</p>
-<h2 id="_description">Description</h2>
-<p>Websocket is an extension to HTTP that emulates plain TCP connections between the client, typically a Web browser, and the server. It uses the HTTP Upgrade mechanism to establish the connection.</p>
-<p>Websocket connections are fully asynchronous, unlike HTTP/1.1 (synchronous) and HTTP/2 (asynchronous, but the server can only initiate streams in response to requests). With Websocket, the client and the server can both send frames at any time without any restriction. It is closer to TCP than any of the HTTP protocols.</p>
-<p>Websocket is an IETF standard. Cowboy supports the standard and all drafts that were previously implemented by browsers, excluding the initial flawed draft sometimes known as &quot;version 0&quot;.</p>
-<h2 id="_websocket_vs_http_2">Websocket vs HTTP/2</h2>
-<p>For a few years Websocket was the only way to have a bidirectional asynchronous connection with the server. This changed when HTTP/2 was introduced. While HTTP/2 requires the client to first perform a request before the server can push data, this is only a minor restriction as the client can do so just as it connects.</p>
-<p>Websocket was designed as a kind-of-TCP channel to a server. It only defines the framing and connection management and lets the developer implement a protocol on top of it. For example you could implement IRC over Websocket and use a Javascript IRC client to speak to the server.</p>
-<p>HTTP/2 on the other hand is just an improvement over the HTTP/1.1 connection and request/response mechanism. It has the same semantics as HTTP/1.1.</p>
-<p>If all you need is to access an HTTP API, then HTTP/2 should be your first choice. On the other hand, if what you need is a different protocol, then you can use Websocket to implement it.</p>
-<h2 id="_implementation">Implementation</h2>
-<p>Cowboy implements Websocket as a protocol upgrade. Once the upgrade is performed from the <code>init/2</code> callback, Cowboy switches to Websocket. Please consult the next chapter for more information on initiating and handling Websocket connections.</p>
-<p>The implementation of Websocket in Cowboy is validated using the Autobahn test suite, which is an extensive suite of tests covering all aspects of the protocol. Cowboy passes the suite with 100% success, including all optional tests.</p>
-<p>Cowboy&apos;s Websocket implementation also includes the permessage-deflate and x-webkit-deflate-frame compression extensions.</p>
-<p>Cowboy will automatically use compression when the <code>compress</code> option is returned from the <code>init/2</code> function.</p>

-<p>Start listening for connections over a clear TCP channel.</p>
-<p>Both HTTP/1.1 and HTTP/2 are supported on this listener. HTTP/2 has two methods of establishing a connection over a clear TCP channel. Both the upgrade and the prior knowledge methods are supported.</p>
-<h2 id="_arguments">Arguments</h2>
-<dl><dt>Name</dt>
-<dd><p>The listener name is used to refer to this listener in future calls, for example when stopping it or when updating the routes defined.</p>
-<p>It can be any Erlang term. An atom is generally good enough, for example <code>api</code>, <code>my_app_clear</code> or <code>my_app_tls</code>.</p>
-</dd>
-<dt>TransportOpts</dt>
-<dd><p>The transport options are where the TCP options, including the listener&apos;s port number, are defined. Transport options are provided as a list of keys and values, for example <code>[{port, 8080}]</code>.</p>
-<p>The available options are documented in the <a href="../ranch_tcp">ranch_tcp(3)</a> manual.</p>
-</dd>
-<dt>ProtocolOpts</dt>
-<dd><p>The protocol options are in a map containing all the options for the different protocols that may be involved when connecting to the listener, including HTTP/1.1 and HTTP/2.</p>
-<p>The HTTP/1.1 options are documented in the <a href="../cowboy_http">cowboy_http(3)</a> manual; and the HTTP/2 options in <a href="../cowboy_http2">cowboy_http2(3)</a>.</p>
-</dd>
-</dl>
-<h2 id="_return_value">Return value</h2>
-<p>An ok tuple is returned on success. It contains the pid of the top-level supervisor for the listener.</p>
-<p>An error tuple is returned on error. The error reason may be any Erlang term.</p>
-<p>A common error is <code>eaddrinuse</code>. It indicates that the port configured for Cowboy is already in use.</p>
-<h2 id="_changelog">Changelog</h2>
-<ul><li><strong>2.0</strong>: HTTP/2 support added.

-<p>cowboy_constraints - Constraints</p>
-<h2 id="_description">Description</h2>
-<p>The module <code>cowboy_constraints</code> defines the built-in constraints in Cowboy and provides an interface for manipulating these constraints.</p>
-<p>Constraints are functions that define what type of input is allowed. They are used throughout Cowboy, from the router to query strings to cookies.</p>
-<h2 id="_exports">Exports</h2>
-<p>Built-in constraints:</p>
-<ul><li><a href="../cowboy_constraints.int">cowboy_constraints:int(3)</a> - Integer constraint
-</li>
-<li><a href="../cowboy_constraints.nonempty">cowboy_constraints:nonempty(3)</a> - Non-empty constraint
-</li>
-</ul>
-<h2 id="_types">Types</h2>

-<p>cowboy_handler - Plain HTTP handlers</p>
-<h2 id="_description">Description</h2>
-<p>The <code>cowboy_handler</code> middleware executes the handler selected by the router or any other preceding middleware.</p>
-<p>This middleware takes the handler module and initial state from the <code>handler</code> and <code>handler_opts</code> environment values, respectively. On completion, it adds a <code>result</code> value to the middleware environment, containing the return value of the <code>terminate/3</code> callback (if defined) and <code>ok</code> otherwise.</p>
-<p>This module also defines a callback interface for handling HTTP requests.</p>
-<h2 id="_callbacks">Callbacks</h2>
-<p>Plain HTTP handlers implement the following interface:</p>

-<p>These two callbacks are common to all handlers.</p>
-<p>Plain HTTP handlers do all their work in the <code>init/2</code> callback. Returning <code>ok</code> terminates the handler. If no response is sent, Cowboy will send a <code>204 No Content</code>.</p>
-<p>The optional <code>terminate/3</code> callback will ultimately be called with the reason for the termination of the handler. Cowboy will terminate the process right after this. There is no need to perform any cleanup in this callback.</p>
-<p>The following terminate reasons are defined for plain HTTP handlers:</p>
-<dl><dt>normal</dt>
-<dd><p>The connection was closed normally.</p>
-</dd>
-<dt>{crash, Class, Reason}</dt>
-<dd><p>A crash occurred in the handler. <code>Class</code> and <code>Reason</code> can be used to obtain more information about the crash. The function <code>erlang:get_stacktrace/0</code> can also be called to obtain the stacktrace of the process when the crash occurred.</p>

-<p>cowboy_loop - Loop handlers</p>
-<h2 id="_description">Description</h2>
-<p>The module <code>cowboy_loop</code> defines a callback interface for long running HTTP connections.</p>
-<p>You should switch to this behavior for long polling, server-sent events and similar long-running requests.</p>
-<p>There are generally two usage patterns:</p>
-<ul><li>Loop until receiving a specific message, then send a response and stop execution (for example long polling);
-</li>
-<li>Or initiate a response in <code>init/2</code> and stream the body in <code>info/3</code> as necessary (for example server-sent events).
-</li>
-</ul>
-<h2 id="_callbacks">Callbacks</h2>
-<p>Loop handlers implement the following interface:</p>

-<p>The <code>init/2</code> callback is common to all handlers. To switch to the loop behavior, it must return <code>cowboy_loop</code> as the first element of the tuple.</p>
-<p>The <code>info/3</code> callback will be called for every Erlang message received. It may choose to continue the receive loop or stop it.</p>
-<p>The optional <code>terminate/3</code> callback will ultimately be called with the reason for the termination of the handler. Cowboy will terminate the process right after this. There is no need to perform any cleanup in this callback.</p>
-<p>The following terminate reasons are defined for loop handlers:</p>
-<dl><dt>stop</dt>
-<dd><p>The handler requested to close the connection by returning a <code>stop</code> tuple.</p>
-</dd>
-<dt>{crash, Class, Reason}</dt>
-<dd><p>A crash occurred in the handler. <code>Class</code> and <code>Reason</code> can be used to obtain more information about the crash. The function <code>erlang:get_stacktrace/0</code> can also be called to obtain the stacktrace of the process when the crash occurred.</p>

-<p>Cowboy will only return the cookie values specified in the fields list, and ignore all others. Fields can be either the name of the cookie requested; the name along with a list of constraints; or the name, a list of constraints and a default value in case the cookie is missing.</p>
-<p>This function will crash if the cookie is missing and no default value is provided. This function will also crash if a constraint fails.</p>
-<p>The name of the cookie must be provided as an atom. The key of the returned map will be that atom. The value may be converted through the use of constraints, making this function able to extract, validate and convert values all in one step.</p>

-<p>The parsed query string is returned as a list of key/value pairs. The key is a binary string. The value is either a binary string, or the atom <code>true</code>. Both key and value are case sensitive.</p>
-<p>The atom <code>true</code> is returned when a key is present in the query string without a value. For example, in the following URIs the key <code>&lt;&lt;&quot;edit&quot;&gt;&gt;</code> will always have the value <code>true</code>:</p>
-<ul><li><code>/posts/42?edit</code>
-</li>
-<li><code>/posts/42?edit&amp;exclusive=1</code>

-<li><code>/posts/42?exclusive=1&amp;edit</code>

-</li>
-</ul>
-<h2 id="_changelog">Changelog</h2>
-<ul><li><strong>2.0</strong>: The parsed value is not longer cached in the Req object.
-</li>
-<li><strong>2.0</strong>: Only the parsed query string is returned, it is no longer wrapped in a tuple.

-<p>Push a resource to the client.</p>
-<p>Cowboy handles push requests the same way as if they came from the client, including the creation of a request handling process, routing and middlewares and so on.</p>
-<p>This function does nothing when the HTTP/1.1 protocol is used. You may call it safely without first checking whether the connection uses HTTP/2.</p>
-<p>The header names must be given as lowercase binary strings. While header names are case insensitive, Cowboy requires them to be given as lowercase to function properly.</p>
-<p>Note that the headers must be the headers the client is expected to send if it were to perform the request. They are therefore request headers, and not response headers.</p>
-<p>By default, Cowboy will use the GET method, an empty query string, and take the scheme, host and port directly from the current request&apos;s URI. You can override them by passing options.</p>
-<p>It is not possible to push resources after sending a response. Any attempt will result in an error.</p>

-<p>Read the request body.</p>
-<p>This function reads a chunk of the request body. A <code>more</code> tuple is returned when more data remains to be read. Call the function repeatedly until an <code>ok</code> tuple is returned to read the entire body.</p>
-<p>An <code>ok</code> tuple with empty data is returned when the request has no body, or when calling this function again after the body has already been read. It is therefore safe to call this function directly. Note that the body can only be read once.</p>
-<p>This function reads the request body from the connection process. The connection process is responsible for reading from the socket. The exact behavior varies depending on the protocol.</p>
-<p>The options therefore are only related to the communication between the request process and the connection process.</p>
-<p>Cowboy will automatically handle protocol details including the expect header, chunked transfer-encoding and others.</p>
-<p>Once the body has been read fully, Cowboy sets the content-length header if it was not previously provided.</p>
-<h2 id="_arguments">Arguments</h2>
-<dl><dt>Req</dt>
-<dd><p>The Req object.</p>
-</dd>
-<dt>Opts</dt>
-<dd><p>A map of body reading options.</p>
-<p>The <code>length</code> option can be used to request smaller or bigger chunks of data to be sent. It is a best effort approach, Cowboy may send more data than configured on occasions. It defaults to 8MB.</p>
-<p>The <code>period</code> indicates how long the connection process will wait before it provides us with the data it received. It defaults to 15 seconds.</p>
-<p>The connection process sends data to the request process when either the <code>length</code> of data or the <code>period</code> of time is reached.</p>
-<p>The <code>timeout</code> option is a safeguard in case the connection process becomes unresponsive. The function will crash if no message was received in that interval. The timeout should be larger than the period. It defaults to the period + 1 second.</p>
-</dd>
-</dl>
-<h2 id="_return_value">Return value</h2>
-<p>A <code>more</code> tuple is returned when there are more data to be read.</p>
-<p>An <code>ok</code> tuple is returned when there are no more data to be read, either because this is the last chunk of data, the body has already been read, or there was no body to begin with.</p>
-<p>The data is always returned as a binary.</p>
-<p>The Req object returned in the tuple must be used for that point onward. It contains a more up to date representation of the request. For example it may have an added content-length header once the body has been read.</p>
-<h2 id="_changelog">Changelog</h2>

-<p>Read the next part of a multipart body.</p>
-<p>This function reads the request body and parses it as multipart. Each parts of a multipart representation have their own headers and body. This function parses and returns headers. Examples of multipart media types are <code>multipart/form-data</code> and <code>multipart/byteranges</code>.</p>
-<p>Cowboy will skip any data remaining until the beginning of the next part. This includes the preamble to the multipart message but also the body of a previous part if it hasn&apos;t been read. Both are skipped automatically when calling this function.</p>
-<p>Cowboy will read the body before parsing in chunks of size up to 64KB, with a period of 5 seconds. This is tailored for reading part headers and might not be the most efficient for skipping the previous part&apos;s body.</p>
-<p>The headers returned are MIME headers, <strong>NOT</strong> HTTP headers. They can be parsed using the functions from the <code>cow_multipart</code> module. In addition, the <code>cow_multipart:form_data/1</code> function can be used to quickly extract information from <code>multipart/form-data</code> representations.</p>
-<!-- @todo Proper link to cow_multipart:form_data.-->
-<p>Once a part has been read, it can not be read again.</p>
-<p>Once the body has been read, Cowboy sets the content-length header if it was not previously provided.</p>
-<!-- @todo Limit the maximum size of multipart headers.-->
-<h2 id="_arguments">Arguments</h2>
-<dl><dt>Req</dt>
-<dd><p>The Req object.</p>
-</dd>
-<dt>Opts</dt>
-<dd><p>A map of body reading options. Please refer to <a href="../cowboy_req.read_body">cowboy_req:read_body(3)</a> for details about each option.</p>
-<p>This function defaults the <code>length</code> to 64KB and the <code>period</code> to 5 seconds.</p>
-</dd>
-</dl>
-<h2 id="_return_value">Return value</h2>
-<p>An <code>ok</code> tuple is returned containing the next part&apos;s headers as a map.</p>
-<p>A <code>done</code> tuple is returned if there are no more parts to read.</p>
-<p>The Req object returned in the tuple must be used for that point onward. It contains a more up to date representation of the request. For example it may have an added content-length header once the body has been read.</p>
-<h2 id="_changelog">Changelog</h2>
-<ul><li><strong>2.0</strong>: Function introduced. Replaces <code>part/1,2</code>.

-<p>Read the body of the current part of the multipart message.</p>
-<p>This function reads the request body and parses it as multipart. Each parts of a multipart representation have their own headers and body. This function returns the body of the current part. Examples of multipart media types are <code>multipart/form-data</code> and <code>multipart/byteranges</code>.</p>
-<p>This function reads a chunk of the part&apos;s body. A <code>more</code> tuple is returned when more data remains to be read. Call the function repeatedly until an <code>ok</code> tuple is returned to read the entire body.</p>
-<p>Once a part has been read, it can not be read again.</p>
-<p>Once the body has been read, Cowboy sets the content-length header if it was not previously provided.</p>
-<!-- @todo Limit the maximum size of multipart headers.-->
-<h2 id="_arguments">Arguments</h2>
-<dl><dt>Req</dt>

-<dt>Opts</dt>
-<dd><p>A map of body reading options. Please refer to <a href="../cowboy_req.read_body">cowboy_req:read_body(3)</a> for details about each option.</p>
-<p>This function uses the same default options as the <a href="../cowboy_req.read_body">cowboy_req:read_body(3)</a> function.</p>
-</dd>
-</dl>
-<h2 id="_return_value">Return value</h2>
-<p>A <code>more</code> tuple is returned when there are more data to be read.</p>
-<p>An <code>ok</code> tuple is returned when there are no more data to be read.</p>
-<p>The data is always returned as a binary.</p>
-<p>The Req object returned in the tuple must be used for that point onward. It contains a more up to date representation of the request. For example it may have an added content-length header once the body has been read.</p>

-<p>Read and parse a urlencoded request body.</p>
-<p>This function reads the request body and parses it as <code>application/x-www-form-urlencoded</code>. It returns a list of key/values.</p>
-<p>The urlencoded media type is used by Web browsers when submitting HTML forms using the POST method.</p>
-<p>Cowboy needs to read the full body before parsing. By default it will read bodies of size up to 64KB. It is possible to provide options to read larger bodies if required.</p>
-<p>Cowboy will automatically handle protocol details including the expect header, chunked transfer-encoding and others.</p>
-<p>Once the body has been read, Cowboy sets the content-length header if it was not previously provided.</p>

-<p>Send the response.</p>
-<p>The header names must be given as lowercase binary strings. While header names are case insensitive, Cowboy requires them to be given as lowercase to function properly.</p>
-<p>Cowboy does not allow duplicate header names. Headers set by this function may overwrite those set by <code>set_resp_header/3</code> and <code>set_resp_headers/2</code>.</p>
-<p>Use <a href="../cowboy_req.set_resp_cookie">cowboy_req:set_resp_cookie(3)</a> instead of this function to set cookies.</p>
-<p>The <code>reply/2,3</code> functions will send the body set previously, if any. The <code>reply/4</code> function always sends the given body, overriding any previously set.</p>
-<p>You do not need to set the content-length header when sending a response body. Cowboy takes care of it automatically. You should however provide a content-type header.</p>
-<p>No further data can be transmitted after this function returns. This includes the push mechanism. Attempting to send two replies, or to push resources after a reply has been sent, will result in an error.</p>

-<p>The response body will be sent when a reply is initiated. Note that the functions <code>stream_reply/2,3</code> and <code>reply/4</code> will override the body set by this function.</p>

-<p>This function may be called as many times as needed after initiating a response using the <a href="../cowboy_req.stream_reply">cowboy_req:stream_reply(3)</a> function.</p>
-<p>The second argument indicates if this call is the final call. Use the <code>nofin</code> value until you know no more data will be sent. The final call should use <code>fin</code> (possibly with an empty data value).</p>
-<p>Note that not using <code>fin</code> for the final call is not an error; Cowboy will take care of it when the request handler terminates if needed. Depending on the resource it may however be more efficient to do it as early as possible.</p>

-<p>Send the response headers.</p>
-<p>The header names must be given as lowercase binary strings. While header names are case insensitive, Cowboy requires them to be given as lowercase to function properly.</p>
-<p>Cowboy does not allow duplicate header names. Headers set by this function may overwrite those set by <code>set_resp_header/3</code>.</p>
-<p>Use <a href="../cowboy_req.set_resp_cookie">cowboy_req:set_resp_cookie(3)</a> instead of this function to set cookies.</p>
-<p>If a response body was set before calling this function, it will not be sent.</p>
-<p>Use <a href="../cowboy_req.stream_body">cowboy_req:stream_body(3)</a> to stream the response body.</p>
-<p>You may want to set the content-length header when using this function, if it is known in advance. This will allow clients using HTTP/2 and HTTP/1.0 to process the response more efficiently.</p>
-<p>The streaming method varies depending on the protocol being used. HTTP/2 will use the usual DATA frames. HTTP/1.1 will use chunked transfer-encoding. HTTP/1.0 will send the body unmodified and close the connection at the end if no content-length was set.</p>

-<p>cowboy_req - HTTP request and response</p>
-<h2 id="_description">Description</h2>
-<p>The module <code>cowboy_req</code> provides functions to access, manipulate and respond to requests.</p>
-<p>There are four types of functions in this module. They can be differentiated by their name and their return type:</p>
-<table rules="all" width="100%" frame="border"
-			cellspacing="0" cellpadding="4">
-<thead><tr><th>Type</th>
-<th>Name pattern</th>
-<th>Return type</th>
-</tr></thead><tbody><tr><td>access</td>
-<td>no verb, parse_*, match_*</td>
-<td><code>Value</code></td>
-</tr>
-<tr><td>question</td>
-<td>has_*</td>
-<td><code>boolean()</code></td>
-</tr>
-<tr><td>modification</td>
-<td>set_*</td>
-<td><code>Req</code></td>
-</tr>
-<tr><td>action</td>
-<td>any other verb</td>
-<td><code>ok | {Result, Value, Req}</code></td>
-</tr>
-</tbody></table>
-<p>Any <code>Req</code> returned must be used in place of the one passed as argument. Functions that perform an action in particular write state in the Req object to make sure you are using the function correctly. For example, it&apos;s only possible to send one response, and to read the body once.</p>

-<p>The module <code>cowboy_rest</code> implements the HTTP state machine.</p>
-<p>Implementing REST handlers is not enough to provide a REST interface; this interface must also follow the REST constraints including HATEOAS (hypermedia as the engine of application state).</p>

-<p>The <code>init/2</code> callback is common to all handlers. To switch to the REST handler behavior, it must return <code>cowboy_rest</code> as the first element of the tuple.</p>
-<p>The <code>Callback/2</code> above represents all the REST-specific callbacks. They are described in the following section of this manual. REST-specific callbacks differ by their name, semantics, result and default values. The default value is the one used when the callback has not been implemented. They otherwise all follow the same interface.</p>
-<p>The <code>stop</code> tuple can be returned to stop REST processing. If no response was sent before then, Cowboy will send a <em>204 No Content</em>.</p>
-<p>The optional <code>terminate/3</code> callback will ultimately be called with the reason for the termination of the handler. Cowboy will terminate the process right after this. There is no need to perform any cleanup in this callback.</p>
-<p>The following terminate reasons are defined for loop handlers:</p>
-<dl><dt>normal</dt>
-<dd><p>The handler terminated normally.</p>
-</dd>
-<dt>{crash, Class, Reason}</dt>
-<dd><p>A crash occurred in the handler. <code>Class</code> and <code>Reason</code> can be used to obtain more information about the crash. The function <code>erlang:get_stacktrace/0</code> can also be called to obtain the stacktrace of the process when the crash occurred.</p>

-<p>Process the request body.</p>
-<p>This function should create or update the resource using the request body.</p>
-<p>For PUT requests, the body is a representation of the resource that is being created or replaced.</p>
-<p>For POST requests, the body is typically application-specific instructions on how to process the request, but it may also be a representation of the resource. When creating a new resource with POST at a different location, return <code>{true, URI}</code> with <code>URI</code> the new location.</p>
-<p>For PATCH requests, the body is a series of instructions on how to update the resource. Patch files or JSON Patch are examples of such media types.</p>
-<p>A response body may be sent. The appropriate media type, charset and language for the response can be retrieved from the Req object using the <code>media_type</code>, <code>charset</code> and <code>language</code> keys, respectively. The body can be set using <a href="../cowboy_req.set_resp_body">cowboy_req:set_resp_body(3)</a>.</p>

-<p>cowboy_router - Router middleware</p>
-<h2 id="_description">Description</h2>
-<p>The <code>cowboy_router</code> middleware maps the requested host and path to the handler to be used for processing the request.</p>
-<p>The router takes the <code>dispatch</code> rules as input from the middleware environment. Dispatch rules are generated by calling the <a href="../cowboy_router.compile">cowboy_router:compile(3)</a> function.</p>
-<p>When a route matches, the router sets the <code>handler</code> and <code>handler_opts</code> middleware environment values containing the handler module and initial state, respectively.</p>
-<p>The router will stop execution when no route matches. It will send a 400 response if no host was found, and a 404 response otherwise.</p>

-<p>The extra options allow you to define how the etag should be calculated and how the MIME type of files should be detected.</p>
-<p>By default the static handler will generate an etag based on the size and modification time of the file. You may disable the etag entirely with <code>{etag, false}</code> or provide a module and function that will be called when needed:</p>

-<p>cowboy_handler - Stream handlers</p>
-<h2 id="_description">Description</h2>
-<p>The module <code>cowboy_stream</code> defines a callback interface and a protocol for handling HTTP streams.</p>
-<p>An HTTP request and its associated response is called a stream. A connection may have many streams. In HTTP/1.1 they are executed sequentially, while in HTTP/2 they are executed concurrently.</p>
-<p>Cowboy calls the stream handler for nearly all events related to a stream. Exceptions vary depending on the protocol.</p>
-<p>Extra care must be taken when implementing stream handlers to ensure compatibility. While some modification of the events and commands is allowed, it is generally not a good idea to completely omit them.</p>
-<h2 id="_callbacks">Callbacks</h2>
-<p>Stream handlers must implement the following interface:</p>

-<p>HTTP/1.1 will initialize a stream only when the request-line and all headers have been received. When errors occur before that point Cowboy will call the callback <code>early_error/5</code> with a partial request, the error reason and the response Cowboy intends to send. All other events go throuh the stream handler using the normal callbacks.</p>
-<p>HTTP/2 will initialize the stream when the <code>HEADERS</code> block has been fully received and decoded. Any protocol error occuring before that will not result in a response being sent and will therefore not go through the stream handler. In addition Cowboy may terminate streams without sending an HTTP response back.</p>
-<p>The stream is initialized by calling <code>init/3</code>. All streams that are initialized will eventually be terminated by calling <code>terminate/3</code>.</p>
-<p>When Cowboy receives data for the stream it will call <code>data/4</code>. The data given is the request body after any transfer decoding has been applied.</p>
-<p>When Cowboy receives a message addressed to a stream, or when Cowboy needs to inform the stream handler that an internal event has occurred, it will call <code>info/3</code>.</p>
-<h2 id="commands">Commands</h2>
-<p>Stream handlers can return a list of commands to be executed from the <code>init/3</code>, <code>data/4</code> and <code>info/3</code> callbacks. In addition, the <code>early_error/5</code> callback must return a response command.</p>
-<!-- @todo We need a &apos;log&apos; command that would call error_logger.-->
-<!-- It&apos;s better than doing in the handlers directly because-->
-<!-- then we can have other stream handlers manipulate those logs.-->
-<!-- @todo We need a command to send a message so that other-->
-<!-- stream handlers can manipulate these messages if necessary.-->

-<p>While no more data can be sent after the <code>fin</code> flag was set, the stream is still tracked by Cowboy until it is stopped by the handler.</p>
-<p>The behavior when stopping a stream for which no response has been sent will vary depending on the protocol. The stream will end successfully as far as the client is concerned.</p>

-<p>The <code>init/2</code> callback is common to all handlers. To upgrade the connection to Websocket, it must return <code>cowboy_websocket</code> as the first element of the tuple.</p>
-<p>Any operation requiring the HTTP request must be done in the <code>init/2</code> function, as the Req object will not be available after it returns. Websocket sub-protocol selection should therefore be done in this function.</p>
-<p>The optional <code>websocket_init/1</code> callback will be called once the connection has been upgraded to Websocket. It can be used to perform any required initialization of the handler.</p>
-<p>Note that the <code>init/2</code> function does not run in the same process as the Websocket callbacks. Any Websocket-specific initialization must be done in <code>websocket_init/1</code>.</p>
-<p>The <code>websocket_handle/2</code> callback will be called for every frame received. The <code>websocket_info/2</code> callback will be called for every Erlang message received.</p>
-<p>All three Websocket callbacks may send one or more frames back to the client (by returning a <code>reply</code> tuple) or terminate the connection (by sending a <code>close</code> frame or returning a <code>stop</code> tuple).</p>
-<p>The optional <code>terminate/3</code> callback will ultimately be called with the reason for the termination of the connection. This callback is common to all handlers. Note that Websocket will not provide the full Req object by default, to save memory.</p>
-<p>Cowboy will terminate the process right after closing the Websocket connection. This means that there is no need to perform any cleanup in the <code>terminate/3</code> callback.</p>
-<p>The following terminate reasons are defined for Websocket connections:</p>
-<dl><dt>normal</dt>
-<dd><p>The connection was closed normally before establishing a Websocket connection. This typically happens if an <code>ok</code> tuple is returned from the <code>init/2</code> callback.</p>
-</dd>
-<dt>remote</dt>
-<dd><p>The remote endpoint closed the connection without giving any further details.</p>
-</dd>
-<dt>{remote, Code, Payload}</dt>
-<dd><p>The remote endpoint closed the connection with the given <code>Code</code> and <code>Payload</code> as the reason.</p>
-</dd>
-<dt>stop</dt>
-<dd><p>The handler requested to close the connection, either by returning a <code>stop</code> tuple or by sending a <code>close</code> frame.</p>
-</dd>
-<dt>timeout</dt>
-<dd><p>The connection has been closed due to inactivity. The timeout value can be configured from <code>init/2</code>.</p>
-</dd>
-<dt>{crash, Class, Reason}</dt>
-<dd><p>A crash occurred in the handler. <code>Class</code> and <code>Reason</code> can be used to obtain more information about the crash. The function <code>erlang:get_stacktrace/0</code> can also be called to obtain the stacktrace of the process when the crash occurred.</p>
-</dd>
-<dt>{error, badencoding}</dt>
-<dd><p>A text frame was sent by the client with invalid encoding. All text frames must be valid UTF-8.</p>
-</dd>
-<dt>{error, badframe}</dt>
-<dd><p>A protocol error has been detected.</p>
-</dd>
-<dt>{error, closed}</dt>
-<dd><p>The socket has been closed brutally without a close frame being received first.</p>
-</dd>
-<dt>{error, Reason}</dt>
-<dd><p>A socket error ocurred.</p>

-<h2 id="_100_continue">100 Continue</h2>
-<p>When the client sends an <code>expect: 100-continue</code> header, Cowboy automatically sends a this status code before trying to read the request body. This behavior can be disabled using the appropriate body option.</p>
-<h2 id="_101_switching_protocols">101 Switching Protocols</h2>
-<p>This is the status code sent when switching to the Websocket protocol.</p>
-<h2 id="_200_ok">200 OK</h2>
-<p>This status code is sent by <code>cowboy_rest</code>.</p>
-<h2 id="_201_created">201 Created</h2>
-<p>This status code is sent by <code>cowboy_rest</code>.</p>
-<h2 id="_202_accepted">202 Accepted</h2>
-<p>This status code is sent by <code>cowboy_rest</code>.</p>
-<h2 id="_204_no_content">204 No Content</h2>
-<p>This status code is sent when the processing of a request ends without any reply having been sent. It may also be sent by <code>cowboy_rest</code> under normal conditions.</p>
-<h2 id="_300_multiple_choices">300 Multiple Choices</h2>
-<p>This status code is sent by <code>cowboy_rest</code>.</p>

-<p>This status code is sent by <code>cowboy_rest</code>.</p>
-<h2 id="_400_bad_request">400 Bad Request</h2>
-<p>Cowboy will send this status code for any of the following reasons:</p>
-<ul><li>Too many empty lines were sent before the request.
-</li>
-<li>The request-line could not be parsed.
-</li>
-<li>Too many headers were sent.
-</li>
-<li>A header name was too long.
-</li>
-<li>A header value was too long.

-[[constraints]]
-== Constraints
-
-Constraints are validation and conversion functions applied
-to user input.
-
-They are used in various places in Cowboy, including the
-router and the `cowboy_req` match functions.
-
-=== Syntax
-
-Constraints are provided as a list of fields. For each field
-in the list, specific constraints can be applied, as well as
-a default value if the field is missing.
-
-A field can take the form of an atom `field`, a tuple with
-constraints `{field, Constraints}` or a tuple with constraints
-and a default value `{field, Constraints, Default}`.
-The `field` form indicates the field is mandatory.
-
-Note that when used with the router, only the second form
-makes sense, as it does not use the default and the field
-is always defined.
-
-Constraints for each field are provided as an ordered list
-of atoms or funs to apply. Built-in constraints are provided
-as atoms, while custom constraints are provided as funs.
-
-When multiple constraints are provided, they are applied in
-the order given. If the value has been modified by a constraint
-then the next one receives the new value.
-
-For example, the following constraints will first validate
-and convert the field `my_value` to an integer, and then
-check that the integer is positive:
-
-[source,erlang]
-----
-PositiveFun = fun
-    (_, V) when V > 0 ->
-        {ok, V};
-    (_, _) ->
-        {error, not_positive}
-end,
-{my_value, [int, PositiveFun]}.
-----
-
-We ignore the first fun argument in this snippet. We shouldn't.
-We will simply learn what it is later in this chapter.
-
-When there's only one constraint, it can be provided directly
-without wrapping it into a list:
-
-[source,erlang]
-----
-{my_value, int}
-----
-
-=== Built-in constraints
-
-Built-in constraints are specified as an atom:
-
-[cols="<,<",options="header"]
-|===
-| Constraint | Description
-| int        | Converts binary value to integer.
-| nonempty   | Ensures the binary value is non-empty.
-|===
-
-=== Custom constraints
-
-Custom constraints are specified as a fun. This fun takes
-two arguments. The first argument indicates the operation
-to be performed, and the second is the value. What the
-value is and what must be returned depends on the operation.
-
-Cowboy currently defines three operations. The operation
-used for validating and converting user input is the `forward`
-operation.
-
-[source,erlang]
-----
-int(forward, Value) ->
-    try
-        {ok, binary_to_integer(Value)}
-    catch _:_ ->
-        {error, not_an_integer}
-    end;
-----
-
-The value must be returned even if it is not converted
-by the constraint.
-
-The `reverse` operation does the opposite: it
-takes a converted value and changes it back to what the
-user input would have been.
-
-[source,erlang]
-----
-int(reverse, Value) ->
-	try
-		{ok, integer_to_binary(Value)}
-	catch _:_ ->
-		{error, not_an_integer}
-	end;
-----
-
-Finally, the `format_error` operation takes an error
-returned by any other operation and returns a formatted
-human-readable error message.
-
-[source,erlang]
-----
-int(format_error, {not_an_integer, Value}) ->
-	io_lib:format("The value ~p is not an integer.", [Value]).
-----
-
-Notice that for this case you get both the error and
-the value that was given to the constraint that produced
-this error.
-
-Cowboy will not catch exceptions coming from constraint
-functions. They should be written to not emit any exceptions.

-
-<p>Constraints are validation and conversion functions applied to user input.</p>
-<p>They are used in various places in Cowboy, including the router and the <code>cowboy_req</code> match functions.</p>
-<h2 id="_syntax">Syntax</h2>
-<p>Constraints are provided as a list of fields. For each field in the list, specific constraints can be applied, as well as a default value if the field is missing.</p>
-<p>A field can take the form of an atom <code>field</code>, a tuple with constraints <code>{field, Constraints}</code> or a tuple with constraints and a default value <code>{field, Constraints, Default}</code>. The <code>field</code> form indicates the field is mandatory.</p>
-<p>Note that when used with the router, only the second form makes sense, as it does not use the default and the field is always defined.</p>
-<p>Constraints for each field are provided as an ordered list of atoms or funs to apply. Built-in constraints are provided as atoms, while custom constraints are provided as funs.</p>
-<p>When multiple constraints are provided, they are applied in the order given. If the value has been modified by a constraint then the next one receives the new value.</p>
-<p>For example, the following constraints will first validate and convert the field <code>my_value</code> to an integer, and then check that the integer is positive:</p>

-[[cookies]]
-== Using cookies
-
-Cookies are a mechanism allowing applications to maintain
-state on top of the stateless HTTP protocol.
-
-Cookies are a name/value store where the names and values are
-stored in plain text. They expire either after a delay
-or when the browser closes. They can be configured on a
-specific domain name or path, and restricted to secure
-resources (sent or downloaded over HTTPS), or restricted
-to the server (disallowing access from client-side scripts).
-
-Cookie names are de facto case sensitive.
-
-Cookies are stored client-side and sent with every subsequent
-request that matches the domain and path for which they were
-stored, until they expire. This can create a non-negligible
-cost.
-
-Cookies should not be considered secure. They are stored on
-the user's computer in plain text, and can be read by any
-program. They can also be read by proxies when using clear
-connections. Always validate the value before using it,
-and never store any sensitive information inside it.
-
-Cookies set by the server are only available in requests
-following the client reception of the response containing
-them.
-
-Cookies may be sent repeatedly. This is often useful to
-update the expiration time and avoid losing a cookie.
-
-=== Setting cookies
-
-By default cookies are defined for the duration of the session:
-
-[source,erlang]
-----
-SessionID = generate_session_id(),
-Req = cowboy_req:set_resp_cookie(<<"sessionid">>, SessionID, Req0).
-----
-
-They can also be set for a duration in seconds:
-
-[source,erlang]
-----
-SessionID = generate_session_id(),
-Req = cowboy_req:set_resp_cookie(<<"sessionid">>, SessionID, Req0,
-    #{max_age => 3600}).
-----
-
-To delete cookies, set `max_age` to 0:
-
-[source,erlang]
-----
-SessionID = generate_session_id(),
-Req = cowboy_req:set_resp_cookie(<<"sessionid">>, SessionID, Req0,
-    #{max_age => 0}).
-----
-
-To restrict cookies to a specific domain and path, the options
-of the same name can be used:
-
-[source,erlang]
-----
-Req = cowboy_req:set_resp_cookie(<<"inaccount">>, <<"1">>, Req0,
-    #{domain => "my.example.org", path => "/account"}).
-----
-
-Cookies will be sent with requests to this domain and all
-its subdomains, and to resources on this path or deeper
-in the path hierarchy.
-
-To restrict cookies to secure channels (typically resources
-available over HTTPS):
-
-[source,erlang]
-----
-SessionID = generate_session_id(),
-Req = cowboy_req:set_resp_cookie(<<"sessionid">>, SessionID, Req0,
-    #{secure => true}).
-----
-
-To prevent client-side scripts from accessing a cookie:
-
-[source,erlang]
-----
-SessionID = generate_session_id(),
-Req = cowboy_req:set_resp_cookie(<<"sessionid">>, SessionID, Req0,
-    #{http_only => true}).
-----
-
-Cookies may also be set client-side, for example using
-Javascript.
-
-=== Reading cookies
-
-The client only ever sends back the cookie name and value.
-All other options that can be set are never sent back.
-
-Cowboy provides two functions for reading cookies. Both
-involve parsing the cookie header(s) and so should not
-be called repeatedly.
-
-You can get all cookies as a key/value list:
-
-[source,erlang]
-Cookies = cowboy_req:parse_cookies(Req),
-{_, Lang} = lists:keyfind(<<"lang">>, 1, Cookies).
-
-Or you can perform a match against cookies and retrieve
-only the ones you need, while at the same time doing
-any required post processing using xref:constraints[constraints].
-This function returns a map:
-
-[source,erlang]
-#{id := ID, lang := Lang} = cowboy_req:match_cookies([id, lang], Req).
-
-You can use constraints to validate the values while matching
-them. The following snippet will crash if the `id` cookie is
-not an integer number or if the `lang` cookie is empty. Additionally
-the `id` cookie value will be converted to an integer term:
-
-[source,erlang]
-CookiesMap = cowboy_req:match_cookies([{id, int}, {lang, nonempty}], Req).
-
-Note that if two cookies share the same name, then the map value
-will be a list of the two cookie values.
-
-A default value can be provided. The default will be used
-if the `lang` cookie is not found. It will not be used if
-the cookie is found but has an empty value:
-
-[source,erlang]
-#{lang := Lang} = cowboy_req:match_cookies([{lang, [], <<"en-US">>}], Req).
-
-If no default is provided and the value is missing, an
-exception is thrown.

-[[erlang_web]]
-== Erlang and the Web
-
-Erlang is the ideal platform for writing Web applications.
-Its features are a perfect match for the requirements of
-modern Web applications.
-
-=== The Web is concurrent
-
-When you access a website there is little concurrency
-involved. A few connections are opened and requests
-are sent through these connections. Then the web page
-is displayed on your screen. Your browser will only
-open up to 4 or 8 connections to the server, depending
-on your settings. This isn't much.
-
-But think about it. You are not the only one accessing
-the server at the same time. There can be hundreds, if
-not thousands, if not millions of connections to the
-same server at the same time.
-
-Even today a lot of systems used in production haven't
-solved the C10K problem (ten thousand concurrent connections).
-And the ones who did are trying hard to get to the next
-step, C100K, and are pretty far from it.
-
-Erlang meanwhile has no problem handling millions of
-connections. At the time of writing there are application
-servers written in Erlang that can handle more than two
-million connections on a single server in a real production
-application, with spare memory and CPU!
-
-The Web is concurrent, and Erlang is a language designed
-for concurrency, so it is a perfect match.
-
-Of course, various platforms need to scale beyond a few
-million connections. This is where Erlang's built-in
-distribution mechanisms come in. If one server isn't
-enough, add more! Erlang allows you to use the same code
-for talking to local processes or to processes in other
-parts of your cluster, which means you can scale very
-quickly if the need arises.
-
-The Web has large userbases, and the Erlang platform was
-designed to work in a distributed setting, so it is a
-perfect match.
-
-Or is it? Surely you can find solutions to handle that many
-concurrent connections with your favorite language... But all
-these solutions will break down in the next few years. Why?
-Firstly because servers don't get any more powerful, they
-instead get a lot more cores and memory. This is only useful
-if your application can use them properly, and Erlang is
-light-years away from anything else in that area. Secondly,
-today your computer and your phone are online, tomorrow your
-watch, goggles, bike, car, fridge and tons of other devices
-will also connect to various applications on the Internet.
-
-Only Erlang is prepared to deal with what's coming.
-
-=== The Web is soft real time
-
-What does soft real time mean, you ask? It means we want the
-operations done as quickly as possible, and in the case of
-web applications, it means we want the data propagated fast.
-
-In comparison, hard real time has a similar meaning, but also
-has a hard time constraint, for example an operation needs to
-be done in under N milliseconds otherwise the system fails
-entirely.
-
-Users aren't that needy yet, they just want to get access
-to their content in a reasonable delay, and they want the
-actions they make to register at most a few seconds after
-they submitted them, otherwise they'll start worrying about
-whether it successfully went through.
-
-The Web is soft real time because taking longer to perform an
-operation would be seen as bad quality of service.
-
-Erlang is a soft real time system. It will always run
-processes fairly, a little at a time, switching to another
-process after a while and preventing a single process to
-steal resources from all others. This means that Erlang
-can guarantee stable low latency of operations.
-
-Erlang provides the guarantees that the soft real time Web
-requires.
-
-=== The Web is asynchronous
-
-Long ago, the Web was synchronous because HTTP was synchronous.
-You fired a request, and then waited for a response. Not anymore.
-It all began when XmlHttpRequest started being used. It allowed
-the client to perform asynchronous calls to the server.
-
-Then Websocket appeared and allowed both the server and the client
-to send data to the other endpoint completely asynchronously. The
-data is contained within frames and no response is necessary.
-
-Erlang processes work the same. They send each other data contained
-within messages and then continue running without needing a response.
-They tend to spend most of their time inactive, waiting for a new
-message, and the Erlang VM happily activate them when one is received.
-
-It is therefore quite easy to imagine Erlang being good at receiving
-Websocket frames, which may come in at unpredictable times, pass the
-data to the responsible processes which are always ready waiting for
-new messages, and perform the operations required by only activating
-the required parts of the system.
-
-The more recent Web technologies, like Websocket of course, but also
-HTTP/2.0, are all fully asynchronous protocols. The concept
-of requests and responses is retained of course, but anything could
-be sent in between, by both the client or the browser, and the
-responses could also be received in a completely different order.
-
-Erlang is by nature asynchronous and really good at it thanks to the
-great engineering that has been done in the VM over the years. It's
-only natural that it's so good at dealing with the asynchronous Web.
-
-=== The Web is omnipresent
-
-The Web has taken a very important part of our lives. We're
-connected at all times, when we're on our phone, using our computer,
-passing time using a tablet while in the bathroom... And this
-isn't going to slow down, every single device at home or on us
-will be connected.
-
-All these devices are always connected. And with the number of
-alternatives to give you access to the content you seek, users
-tend to not stick around when problems arise. Users today want
-their applications to be always available and if it's having
-too many issues they just move on.
-
-Despite this, when developers choose a product to use for building
-web applications, their only concern seems to be "Is it fast?",
-and they look around for synthetic benchmarks showing which one
-is the fastest at sending "Hello world" with only a handful
-concurrent connections. Web benchmarks haven't been representative
-of reality in a long time, and are drifting further away as
-time goes on.
-
-What developers should really ask themselves is "Can I service
-all my users with no interruption?" and they'd find that they have
-two choices. They can either hope for the best, or they can use
-Erlang.
-
-Erlang is built for fault tolerance. When writing code in any other
-language, you have to check all the return values and act accordingly
-to avoid any unforeseen issues. If you're lucky, you won't miss
-anything important. When writing Erlang code, you can just check
-the success condition and ignore all errors. If an error happens,
-the Erlang process crashes and is then restarted by a special
-process called a supervisor.
-
-Erlang developers thus have no need to fear unhandled
-errors, and can focus on handling only the errors that should
-give some feedback to the user and let the system take care of
-the rest. This also has the advantage of allowing them to write
-a lot less code, and let them sleep at night.
-
-Erlang's fault tolerance oriented design is the first piece of
-what makes it the best choice for the omnipresent, always available
-Web.
-
-The second piece is Erlang's built-in distribution. Distribution
-is a key part of building a fault tolerant system, because it
-allows you to handle bigger failures, like a whole server going
-down, or even a data center entirely.
-
-Fault tolerance and distribution are important today, and will be
-vital in the future of the Web. Erlang is ready.
-
-=== Learn Erlang
-
-If you are new to Erlang, you may want to grab a book or
-two to get started. Those are my recommendations as the
-author of Cowboy.
-
-==== The Erlanger Playbook
-
-The Erlanger Playbook is an ebook I am currently writing,
-which covers a number of different topics from code to
-documentation to testing Erlang applications. It also has
-an Erlang section where it covers directly the building
-blocks and patterns, rather than details like the syntax.
-
-You can most likely read it as a complete beginner, but
-you will need a companion book to make the most of it.
-Buy it from the https://ninenines.eu[Nine Nines website].
-
-==== Programming Erlang
-
-This book is from one of the creator of Erlang, Joe
-Armstrong. It provides a very good explanation of what
-Erlang is and why it is so. It serves as a very good
-introduction to the language and platform.
-
-The book is http://pragprog.com/book/jaerlang2/programming-erlang[Programming Erlang],
-and it also features a chapter on Cowboy.
-
-==== Learn You Some Erlang for Great Good!
-
-http://learnyousomeerlang.com[LYSE] is a much more complete
-book covering many aspects of Erlang, while also providing
-stories and humor. Be warned: it's pretty verbose. It comes
-with a free online version and a more refined paper and
-ebook version.

-<h1 class="lined-header"><span>Erlang and the Web</span></h1>
-
-<p>Erlang is the ideal platform for writing Web applications. Its features are a perfect match for the requirements of modern Web applications.</p>
-<h2 id="_the_web_is_concurrent">The Web is concurrent</h2>
-<p>When you access a website there is little concurrency involved. A few connections are opened and requests are sent through these connections. Then the web page is displayed on your screen. Your browser will only open up to 4 or 8 connections to the server, depending on your settings. This isn&apos;t much.</p>
-<p>But think about it. You are not the only one accessing the server at the same time. There can be hundreds, if not thousands, if not millions of connections to the same server at the same time.</p>
-<p>Even today a lot of systems used in production haven&apos;t solved the C10K problem (ten thousand concurrent connections). And the ones who did are trying hard to get to the next step, C100K, and are pretty far from it.</p>
-<p>Erlang meanwhile has no problem handling millions of connections. At the time of writing there are application servers written in Erlang that can handle more than two million connections on a single server in a real production application, with spare memory and CPU!</p>
-<p>The Web is concurrent, and Erlang is a language designed for concurrency, so it is a perfect match.</p>
-<p>Of course, various platforms need to scale beyond a few million connections. This is where Erlang&apos;s built-in distribution mechanisms come in. If one server isn&apos;t enough, add more! Erlang allows you to use the same code for talking to local processes or to processes in other parts of your cluster, which means you can scale very quickly if the need arises.</p>
-<p>The Web has large userbases, and the Erlang platform was designed to work in a distributed setting, so it is a perfect match.</p>
-<p>Or is it? Surely you can find solutions to handle that many concurrent connections with your favorite language... But all these solutions will break down in the next few years. Why? Firstly because servers don&apos;t get any more powerful, they instead get a lot more cores and memory. This is only useful if your application can use them properly, and Erlang is light-years away from anything else in that area. Secondly, today your computer and your phone are online, tomorrow your watch, goggles, bike, car, fridge and tons of other devices will also connect to various applications on the Internet.</p>
-<p>Only Erlang is prepared to deal with what&apos;s coming.</p>
-<h2 id="_the_web_is_soft_real_time">The Web is soft real time</h2>
-<p>What does soft real time mean, you ask? It means we want the operations done as quickly as possible, and in the case of web applications, it means we want the data propagated fast.</p>
-<p>In comparison, hard real time has a similar meaning, but also has a hard time constraint, for example an operation needs to be done in under N milliseconds otherwise the system fails entirely.</p>
-<p>Users aren&apos;t that needy yet, they just want to get access to their content in a reasonable delay, and they want the actions they make to register at most a few seconds after they submitted them, otherwise they&apos;ll start worrying about whether it successfully went through.</p>
-<p>The Web is soft real time because taking longer to perform an operation would be seen as bad quality of service.</p>
-<p>Erlang is a soft real time system. It will always run processes fairly, a little at a time, switching to another process after a while and preventing a single process to steal resources from all others. This means that Erlang can guarantee stable low latency of operations.</p>
-<p>Erlang provides the guarantees that the soft real time Web requires.</p>
-<h2 id="_the_web_is_asynchronous">The Web is asynchronous</h2>
-<p>Long ago, the Web was synchronous because HTTP was synchronous. You fired a request, and then waited for a response. Not anymore. It all began when XmlHttpRequest started being used. It allowed the client to perform asynchronous calls to the server.</p>
-<p>Then Websocket appeared and allowed both the server and the client to send data to the other endpoint completely asynchronously. The data is contained within frames and no response is necessary.</p>
-<p>Erlang processes work the same. They send each other data contained within messages and then continue running without needing a response. They tend to spend most of their time inactive, waiting for a new message, and the Erlang VM happily activate them when one is received.</p>
-<p>It is therefore quite easy to imagine Erlang being good at receiving Websocket frames, which may come in at unpredictable times, pass the data to the responsible processes which are always ready waiting for new messages, and perform the operations required by only activating the required parts of the system.</p>
-<p>The more recent Web technologies, like Websocket of course, but also HTTP/2.0, are all fully asynchronous protocols. The concept of requests and responses is retained of course, but anything could be sent in between, by both the client or the browser, and the responses could also be received in a completely different order.</p>
-<p>Erlang is by nature asynchronous and really good at it thanks to the great engineering that has been done in the VM over the years. It&apos;s only natural that it&apos;s so good at dealing with the asynchronous Web.</p>
-<h2 id="_the_web_is_omnipresent">The Web is omnipresent</h2>
-<p>The Web has taken a very important part of our lives. We&apos;re connected at all times, when we&apos;re on our phone, using our computer, passing time using a tablet while in the bathroom... And this isn&apos;t going to slow down, every single device at home or on us will be connected.</p>
-<p>All these devices are always connected. And with the number of alternatives to give you access to the content you seek, users tend to not stick around when problems arise. Users today want their applications to be always available and if it&apos;s having too many issues they just move on.</p>
-<p>Despite this, when developers choose a product to use for building web applications, their only concern seems to be &quot;Is it fast?&quot;, and they look around for synthetic benchmarks showing which one is the fastest at sending &quot;Hello world&quot; with only a handful concurrent connections. Web benchmarks haven&apos;t been representative of reality in a long time, and are drifting further away as time goes on.</p>
-<p>What developers should really ask themselves is &quot;Can I service all my users with no interruption?&quot; and they&apos;d find that they have two choices. They can either hope for the best, or they can use Erlang.</p>
-<p>Erlang is built for fault tolerance. When writing code in any other language, you have to check all the return values and act accordingly to avoid any unforeseen issues. If you&apos;re lucky, you won&apos;t miss anything important. When writing Erlang code, you can just check the success condition and ignore all errors. If an error happens, the Erlang process crashes and is then restarted by a special process called a supervisor.</p>
-<p>Erlang developers thus have no need to fear unhandled errors, and can focus on handling only the errors that should give some feedback to the user and let the system take care of the rest. This also has the advantage of allowing them to write a lot less code, and let them sleep at night.</p>
-<p>Erlang&apos;s fault tolerance oriented design is the first piece of what makes it the best choice for the omnipresent, always available Web.</p>
-<p>The second piece is Erlang&apos;s built-in distribution. Distribution is a key part of building a fault tolerant system, because it allows you to handle bigger failures, like a whole server going down, or even a data center entirely.</p>
-<p>Fault tolerance and distribution are important today, and will be vital in the future of the Web. Erlang is ready.</p>
-<h2 id="_learn_erlang">Learn Erlang</h2>
-<p>If you are new to Erlang, you may want to grab a book or two to get started. Those are my recommendations as the author of Cowboy.</p>
-<h4 id="_the_erlanger_playbook">The Erlanger Playbook</h4>
-<p>The Erlanger Playbook is an ebook I am currently writing, which covers a number of different topics from code to documentation to testing Erlang applications. It also has an Erlang section where it covers directly the building blocks and patterns, rather than details like the syntax.</p>
-<p>You can most likely read it as a complete beginner, but you will need a companion book to make the most of it. Buy it from the <a href="https://ninenines.eu">Nine Nines website</a>.</p>
-<h4 id="_programming_erlang">Programming Erlang</h4>
-<p>This book is from one of the creator of Erlang, Joe Armstrong. It provides a very good explanation of what Erlang is and why it is so. It serves as a very good introduction to the language and platform.</p>
-<p>The book is <a href="http://pragprog.com/book/jaerlang2/programming-erlang">Programming Erlang</a>, and it also features a chapter on Cowboy.</p>
-<h4 id="_learn_you_some_erlang_for_great_good">Learn You Some Erlang for Great Good!</h4>
-<p><a href="http://learnyousomeerlang.com">LYSE</a> is a much more complete book covering many aspects of Erlang, while also providing stories and humor. Be warned: it&apos;s pretty verbose. It comes with a free online version and a more refined paper and ebook version.</p>

-[[flow_diagram]]
-== Flow diagram
-
-Cowboy is a lightweight HTTP server with support for HTTP/1.1,
-HTTP/2 and Websocket.
-
-It is built on top of Ranch. Please see the Ranch guide for more
-information about how the network connections are handled.
-
-=== Overview
-
-image::http_req_resp.png[HTTP request/response flowchart]
-
-As you can see on the diagram, the client
-begins by connecting to the server. This step is handled
-by a Ranch acceptor, which is a process dedicated to
-accepting new connections.
-
-After Ranch accepts a new connection, whether it is an
-HTTP/1.1 or HTTP/2 connection, Cowboy starts receiving
-requests and handling them.
-
-In HTTP/1.1 all requests come sequentially. In HTTP/2
-the requests may arrive and be processed concurrently.
-
-When a request comes in, Cowboy creates a stream, which
-is a set of request/response and all the events associated
-with them. The protocol code in Cowboy defers the handling
-of these streams to stream handler modules. When you
-configure Cowboy you may define one or more module that
-will receive all events associated with a stream, including
-the request, response, bodies, Erlang messages and more.
-
-By default Cowboy comes configured with a stream handler
-called `cowboy_stream_h`. This stream handler will create
-a new process for every request coming in, and then
-communicate with this process to read the body or send
-a response back. The request process executes middlewares
-which, by default, including the router and then the
-execution of handlers. Like stream handlers, middlewares
-may also be customized.
-
-A response may be sent at almost any point in this
-diagram. If the response must be sent before the stream
-is initialized (because an error occurred early, for
-example) then stream handlers receive a special event
-indicating this error.
-
-=== Protocol-specific headers
-
-Cowboy takes care of protocol-specific headers and prevents
-you from sending them manually. For HTTP/1.1 this includes
-the `transfer-encoding` and `connection` headers. For HTTP/2
-this includes the colon headers like `:status`.
-
-Cowboy will also remove protocol-specific headers from
-requests before passing them to stream handlers. Cowboy
-tries to hide the implementation details of all protocols
-as well as possible.
-
-=== Number of processes per connection
-
-By default, Cowboy will use one process per connection,
-plus one process per set of request/response (called a
-stream, internally).
-
-The reason it creates a new process for every request is due
-to the requirements of HTTP/2 where requests are executed
-concurrently and independently from the connection. The
-frames from the different requests end up interleaved on
-the single TCP connection.
-
-The request processes are never reused. There is therefore
-no need to perform any cleanup after the response has been
-sent. The process will terminate and Erlang/OTP will reclaim
-all memory at once.
-
-Cowboy ultimately does not require more than one process
-per connection. It is possible to interact with the connection
-directly from a stream handler, a low level interface to Cowboy.
-They are executed from within the connection process, and can
-handle the incoming requests and send responses. This is however
-not recommended in normal circumstances, as a stream handler
-taking too long to execute could have a negative impact on
-concurrent requests or the state of the connection itself.
-
-=== Date header
-
-Because querying for the current date and time can be expensive,
-Cowboy generates one 'Date' header value every second, shares it
-to all other processes, which then simply copy it in the response.
-This allows compliance with HTTP/1.1 with no actual performance loss.
-
-=== Binaries
-
-Cowboy makes extensive use of binaries.
-
-Binaries are more efficient than lists for representing
-strings because they take less memory space. Processing
-performance can vary depending on the operation. Binaries
-are known for generally getting a great boost if the code
-is compiled natively. Please see the HiPE documentation
-for more details.
-
-Binaries may end up being shared between processes. This
-can lead to some large memory usage when one process keeps
-the binary data around forever without freeing it. If you
-see some weird memory usage in your application, this might
-be the cause.

-[[getting_started]]
-== Getting started
-
-Erlang is more than a language, it is also an operating system
-for your applications. Erlang developers rarely write standalone
-modules, they write libraries or applications, and then bundle
-those into what is called a release. A release contains the
-Erlang VM plus all applications required to run the node, so
-it can be pushed to production directly.
-
-This chapter walks you through all the steps of setting up
-Cowboy, writing your first application and generating your first
-release. At the end of this chapter you should know everything
-you need to push your first Cowboy application to production.
-
-=== Prerequisites
-
-We are going to use the https://github.com/ninenines/erlang.mk[Erlang.mk]
-build system. If you are using Windows, please check the
-http://erlang.mk/guide/installation.html[Installation instructions]
-to get your environment setup before you continue.
-
-=== Bootstrap
-
-First, let's create the directory for our application.
-
-[source,bash]
-$ mkdir hello_erlang
-$ cd hello_erlang
-
-Then we need to download Erlang.mk. Either use the following
-command or download it manually.
-
-[source,bash]
-$ wget https://erlang.mk/erlang.mk
-
-We can now bootstrap our application. Since we are going to generate
-a release, we will also bootstrap it at the same time.
-
-[source,bash]
-$ make -f erlang.mk bootstrap bootstrap-rel
-
-This creates a Makefile, a base application, and the release files
-necessary for creating the release. We can already build and start
-this release.
-
-[source,bash]
-----
-$ make run
-...
-([email protected])1>
-----
-
-Entering the command `i().` will show the running processes, including
-one called `hello_erlang_sup`. This is the supervisor for our
-application.
-
-The release currently does nothing. In the rest of this chapter we
-will add Cowboy as a dependency and write a simple "Hello world!"
-handler.
-
-=== Cowboy setup
-
-We will modify the 'Makefile' to tell the build system it needs to
-fetch and compile Cowboy:
-
-[source,makefile]
-----
-PROJECT = hello_erlang
-
-DEPS = cowboy
-dep_cowboy_commit = 2.1.0
-
-DEP_PLUGINS = cowboy
-
-include erlang.mk
-----
-
-We also tell the build system to load the plugins Cowboy provides.
-These include predefined templates that we will use soon.
-
-If you do `make run` now, Cowboy will be included in the release
-and started automatically. This is not enough however, as Cowboy
-doesn't do anything by default. We still need to tell Cowboy to
-listen for connections.
-
-=== Listening for connections
-
-First we define the routes that Cowboy will use to map requests
-to handler modules, and then we start the listener. This is best
-done at application startup.
-
-Open the 'src/hello_erlang_app.erl' file and add the necessary
-code to the `start/2` function to make it look like this:
-
-[source,erlang]
-----
-start(_Type, _Args) ->
-    Dispatch = cowboy_router:compile([
-        {'_', [{"/", hello_handler, []}]}
-    ]),
-    {ok, _} = cowboy:start_clear(my_http_listener,
-        [{port, 8080}],
-        #{env => #{dispatch => Dispatch}}
-    ),
-    hello_erlang_sup:start_link().
-----
-
-Routes are explained in details in the xref:routing[Routing]
-chapter. For this tutorial we map the path `/` to the handler
-module `hello_handler`. This module doesn't exist yet.
-
-Build and start the release, then open http://localhost:8080
-in your browser. You will get a 500 error because the module is missing.
-Any other URL, like http://localhost:8080/test, will result in a
-404 error.
-
-=== Handling requests
-
-Cowboy features different kinds of handlers, including REST
-and Websocket handlers. For this tutorial we will use a plain
-HTTP handler.
-
-Generate a handler from a template:
-
-[source,bash]
-$ make new t=cowboy.http n=hello_handler
-
-Then, open the 'src/hello_handler.erl' file and modify
-the `init/2` function like this to send a reply.
-
-[source,erlang]
-----
-init(Req0, State) ->
-    Req = cowboy_req:reply(200,
-        #{<<"content-type">> => <<"text/plain">>},
-        <<"Hello Erlang!">>,
-        Req0),
-    {ok, Req, State}.
-----
-
-What the above code does is send a 200 OK reply, with the
-Content-type header set to `text/plain` and the response
-body set to `Hello Erlang!`.
-
-If you run the release and open http://localhost:8080
-in your browser, you should get a nice `Hello Erlang!` displayed!

-[[handlers]]
-== Handlers
-
-Handlers are Erlang modules that handle HTTP requests.
-
-=== Plain HTTP handlers
-
-The most basic handler in Cowboy implements the mandatory
-`init/2` callback, manipulates the request, optionally
-sends a response and then returns.
-
-This callback receives the xref:req[Req object] and the initial
-state defined in the xref:routing[router configuration].
-
-A handler that does nothing would look like this:
-
-[source,erlang]
-----
-init(Req, State) ->
-    {ok, Req, State}.
-----
-
-Despite sending no reply, a `204 No Content` response will be
-sent to the client, as Cowboy makes sure that a response is
-sent for every request.
-
-We need to use the Req object to reply.
-
-[source,erlang]
-----
-init(Req0, State) ->
-    Req = cowboy_req:reply(200, #{
-        <<"content-type">> => <<"text/plain">>
-    }, <<"Hello World!">>, Req0),
-    {ok, Req, State}.
-----
-
-Cowboy will immediately send a response when `cowboy:reply/4`
-is called.
-
-We then return a 3-tuple. `ok` means that the handler ran
-successfully. We also give the modified Req back to Cowboy.
-
-The last value of the tuple is a state that will be used
-in every subsequent callbacks to this handler. Plain HTTP
-handlers only have one additional callback, the optional
-and rarely used `terminate/3`.
-
-=== Other handlers
-
-The `init/2` callback can also be used to inform Cowboy
-that this is a different kind of handler and that Cowboy
-should switch to it. To do this you simply need to return
-the module name of the handler type you want to switch to.
-
-Cowboy comes with three handler types you can switch to:
-xref:rest_handlers[cowboy_rest], xref:ws_handlers[cowboy_websocket]
-and xref:loop_handlers[cowboy_loop]. In addition to those you
-can define your own handler types.
-
-Switching is simple. Instead of returning `ok`, you simply
-return the name of the handler type you want to use. The
-following snippet switches to a Websocket handler:
-
-[source,erlang]
-----
-init(Req, State) ->
-    {cowboy_websocket, Req, State}.
-----
-
-=== Cleaning up
-
-All handler types provide the optional `terminate/3` callback.
-
-[source,erlang]
-----
-terminate(_Reason, _Req, _State) ->
-    ok.
-----
-
-This callback is strictly reserved for any required cleanup.
-You cannot send a response from this function. There is no
-other return value.
-
-This callback is optional because it is rarely necessary.
-Cleanup should be done in separate processes directly (by
-monitoring the handler process to detect when it exits).
-
-Cowboy does not reuse processes for different requests. The
-process will terminate soon after this call returns.

-== Introduction
-
-Cowboy is a small, fast and modern HTTP server for Erlang/OTP.
-
-Cowboy aims to provide a complete xref:modern_web[modern Web stack].
-This includes HTTP/1.1, HTTP/2, Websocket, Server-Sent Events and
-Webmachine-based REST.
-
-Cowboy comes with functions for introspection and tracing, enabling
-developers to know precisely what is happening at any time. Its modular
-design also easily enable developers to add instrumentation.
-
-Cowboy is a high quality project. It has a small code base, is very
-efficient (both in latency and memory use) and can easily be embedded
-in another application.
-
-Cowboy is clean Erlang code. It includes hundreds of tests and its code
-is fully compliant with the Dialyzer. It is also well documented and
-features a Function Reference, a User Guide and numerous Tutorials.
-
-=== Prerequisites
-
-Beginner Erlang knowledge is recommended for reading this guide.
-
-Knowledge of the HTTP protocol is recommended but not required, as it
-will be detailed throughout the guide.
-
-=== Supported platforms
-
-Cowboy is tested and supported on Linux, FreeBSD, Windows and OSX.
-
-Cowboy has been reported to work on other platforms, but we make no
-guarantee that the experience will be safe and smooth. You are advised
-to perform the necessary testing and security audits prior to deploying
-on other platforms.
-
-Cowboy is developed for Erlang/OTP 19.0 and newer.
-
-=== License
-

-[[listeners]]
-== Listeners
-
-A listener is a set of processes that listens on a port for
-new connections. Incoming connections get handled by Cowboy.
-Depending on the connection handshake, one or another protocol
-may be used.
-
-This chapter is specific to Cowboy. Please refer to the
-https://ninenines.eu/docs/en/ranch/1.3/guide/listeners/[Ranch User Guide]
-for more information about listeners.
-
-Cowboy provides two types of listeners: one listening for
-clear TCP connections, and one listening for secure TLS
-connections. Both of them support the HTTP/1.1 and HTTP/2
-protocols.
-
-=== Clear TCP listener
-
-The clear TCP listener will accept connections on the
-given port. A typical HTTP server would listen on port 80.
-Port 80 requires special permissions on most platforms
-however so a common alternative is port 8080.
-
-The following snippet starts listening for connections
-on port 8080:
-
-[source,erlang]
-----
-start(_Type, _Args) ->
-    Dispatch = cowboy_router:compile([
-        {'_', [{"/", hello_handler, []}]}
-    ]),
-    {ok, _} = cowboy:start_clear(my_http_listener,
-        [{port, 8080}],
-        #{env => #{dispatch => Dispatch}}
-    ),
-    hello_erlang_sup:start_link().
-----
-
-The xref:getting_started[Getting Started] chapter uses a
-clear TCP listener.
-
-Clients connecting to Cowboy on the clear listener port are
-expected to use either HTTP/1.1 or HTTP/2.
-
-Cowboy supports both methods of initiating a clear
-HTTP/2 connection: through the Upgrade mechanism
-(https://tools.ietf.org/html/rfc7540#section-3.2[RFC 7540 3.2])
-or by sending the preface directly
-(https://tools.ietf.org/html/rfc7540#section-3.4[RFC 7540 3.4]).
-
-Compatibility with HTTP/1.0 is provided by Cowboy's HTTP/1.1
-implementation.
-
-=== Secure TLS listener
-
-The secure TLS listener will accept connections on the
-given port. A typical HTTPS server would listen on port 443.
-Port 443 requires special permissions on most platforms
-however so a common alternative is port 8443.
-
-// @todo Make a complete list of restrictions.
-
-The function provided by Cowboy will ensure that the TLS
-options given are following the HTTP/2 RFC with regards
-to security. For example some TLS extensions or ciphers
-may be disabled. This also applies to HTTP/1.1 connections
-on this listener. If this is not desirable, Ranch can be
-used directly to setup a custom listener.
-
-[source,erlang]
-----
-start(_Type, _Args) ->
-    Dispatch = cowboy_router:compile([
-        {'_', [{"/", hello_handler, []}]}
-    ]),
-    {ok, _} = cowboy:start_tls(my_http_listener,
-        [
-            {port, 8443},
-            {certfile, "/path/to/certfile"},
-            {keyfile, "/path/to/keyfile"}
-        ],
-        #{env => #{dispatch => Dispatch}}
-    ),
-    hello_erlang_sup:start_link().
-----
-
-Clients connecting to Cowboy on the secure listener are
-expected to use the ALPN TLS extension to indicate what
-protocols they understand. Cowboy always prefers HTTP/2
-over HTTP/1.1 when both are supported. When neither are
-supported by the client, or when the ALPN extension was
-missing, Cowboy expects HTTP/1.1 to be used.
-
-Cowboy also advertises HTTP/2 support through the older
-NPN TLS extension for compatibility. Note however that
-this support will likely not be enabled by default when
-Cowboy 2.0 gets released.
-
-Compatibility with HTTP/1.0 is provided by Cowboy's HTTP/1.1
-implementation.
-
-=== Protocol configuration
-
-The HTTP/1.1 and HTTP/2 protocols share the same semantics;
-only their framing differs. The first is a text protocol and
-the second a binary protocol.
-
-Cowboy doesn't separate the configuration for HTTP/1.1 and
-HTTP/2. Everything goes into the same map. Many options are
-shared.
-
-// @todo Describe good to know options for both protocols?
-// Maybe do that in separate chapters?

-<p>Clients connecting to Cowboy on the secure listener are expected to use the ALPN TLS extension to indicate what protocols they understand. Cowboy always prefers HTTP/2 over HTTP/1.1 when both are supported. When neither are supported by the client, or when the ALPN extension was missing, Cowboy expects HTTP/1.1 to be used.</p>
-<p>Cowboy also advertises HTTP/2 support through the older NPN TLS extension for compatibility. Note however that this support will likely not be enabled by default when Cowboy 2.0 gets released.</p>
-<p>Compatibility with HTTP/1.0 is provided by Cowboy&apos;s HTTP/1.1 implementation.</p>
-<h2 id="_protocol_configuration">Protocol configuration</h2>
-<p>The HTTP/1.1 and HTTP/2 protocols share the same semantics; only their framing differs. The first is a text protocol and the second a binary protocol.</p>
-<p>Cowboy doesn&apos;t separate the configuration for HTTP/1.1 and HTTP/2. Everything goes into the same map. Many options are shared.</p>
-<!-- @todo Describe good to know options for both protocols?-->
-<!-- Maybe do that in separate chapters?-->

-[[loop_handlers]]
-== Loop handlers
-
-Loop handlers are a special kind of HTTP handlers used when the
-response can not be sent right away. The handler enters instead
-a receive loop waiting for the right message before it can send
-a response.
-
-Loop handlers are used for requests where a response might not
-be immediately available, but where you would like to keep the
-connection open for a while in case the response arrives. The
-most known example of such practice is known as long polling.
-
-Loop handlers can also be used for requests where a response is
-partially available and you need to stream the response body
-while the connection is open. The most known example of such
-practice is server-sent events.
-
-While the same can be accomplished using plain HTTP handlers,
-it is recommended to use loop handlers because they are well-tested
-and allow using built-in features like hibernation and timeouts.
-
-Loop handlers essentially wait for one or more Erlang messages
-and feed these messages to the `info/3` callback. It also features
-the `init/2` and `terminate/3` callbacks which work the same as
-for plain HTTP handlers.
-
-=== Initialization
-
-The `init/2` function must return a `cowboy_loop` tuple to enable
-loop handler behavior. This tuple may optionally contain
-a timeout value and/or the atom `hibernate` to make the
-process enter hibernation until a message is received.
-
-This snippet enables the loop handler:
-
-[source,erlang]
-----
-init(Req, State) ->
-    {cowboy_loop, Req, State}.
-----
-
-This also makes the process hibernate:
-
-[source,erlang]
-----
-init(Req, State) ->
-    {cowboy_loop, Req, State, hibernate}.
-----
-
-=== Receive loop
-
-Once initialized, Cowboy will wait for messages to arrive
-in the process' mailbox. When a message arrives, Cowboy
-calls the `info/3` function with the message, the Req object
-and the handler's state.
-
-The following snippet sends a reply when it receives a
-`reply` message from another process, or waits for another
-message otherwise.
-
-[source,erlang]
-----
-info({reply, Body}, Req, State) ->
-    cowboy_req:reply(200, #{}, Body, Req),
-    {stop, Req, State};
-info(_Msg, Req, State) ->
-    {ok, Req, State, hibernate}.
-----
-
-Do note that the `reply` tuple here may be any message
-and is simply an example.
-
-This callback may perform any necessary operation including
-sending all or parts of a reply, and will subsequently
-return a tuple indicating if more messages are to be expected.
-
-The callback may also choose to do nothing at all and just
-skip the message received.
-
-If a reply is sent, then the `stop` tuple should be returned.
-This will instruct Cowboy to end the request.
-
-Otherwise an `ok` tuple should be returned.
-
-=== Streaming loop
-
-Another common case well suited for loop handlers is
-streaming data received in the form of Erlang messages.
-This can be done by initiating a chunked reply in the
-`init/2` callback and then using `cowboy_req:chunk/2`
-every time a message is received.
-
-The following snippet does exactly that. As you can see
-a chunk is sent every time an `event` message is received,
-and the loop is stopped by sending an `eof` message.
-
-[source,erlang]
-----
-init(Req, State) ->
-    Req2 = cowboy_req:stream_reply(200, Req),
-    {cowboy_loop, Req2, State}.
-
-info(eof, Req, State) ->
-    {stop, Req, State};
-info({event, Data}, Req, State) ->
-    cowboy_req:stream_body(Data, nofin, Req),
-    {ok, Req, State};
-info(_Msg, Req, State) ->
-    {ok, Req, State}.
-----
-
-=== Cleaning up
-
-It is recommended that you set the connection header to
-`close` when replying, as this process may be reused for
-a subsequent request.
-
-Please refer to the xref:handlers[Handlers chapter]
-for general instructions about cleaning up.
-
-=== Hibernate
-
-To save memory, you may hibernate the process in between
-messages received. This is done by returning the atom
-`hibernate` as part of the `loop` tuple callbacks normally
-return. Just add the atom at the end and Cowboy will hibernate
-accordingly.

-[[middlewares]]
-== Middlewares
-
-Cowboy delegates the request processing to middleware components.
-By default, two middlewares are defined, for the routing and handling
-of the request, as is detailed in most of this guide.
-
-Middlewares give you complete control over how requests are to be
-processed. You can add your own middlewares to the mix or completely
-change the chain of middlewares as needed.
-
-Cowboy will execute all middlewares in the given order, unless one
-of them decides to stop processing.
-
-=== Usage
-
-Middlewares only need to implement a single callback: `execute/2`.
-It is defined in the `cowboy_middleware` behavior.
-
-This callback has two arguments. The first is the `Req` object.
-The second is the environment.
-
-Middlewares can return one of three different values:
-
-* `{ok, Req, Env}` to continue the request processing
-* `{suspend, Module, Function, Args}` to hibernate
-* `{stop, Req}` to stop processing and move on to the next request
-
-Of note is that when hibernating, processing will resume on the given
-MFA, discarding all previous stacktrace. Make sure you keep the `Req`
-and `Env` in the arguments of this MFA for later use.
-
-If an error happens during middleware processing, Cowboy will not try
-to send an error back to the socket, the process will just crash. It
-is up to the middleware to make sure that a reply is sent if something
-goes wrong.
-
-=== Configuration
-
-The middleware environment is defined as the `env` protocol option.
-In the previous chapters we saw it briefly when we needed to pass
-the routing information. It is a list of tuples with the first
-element being an atom and the second any Erlang term.
-
-Two values in the environment are reserved:
-
-* `listener` contains the name of the listener
-* `result` contains the result of the processing
-
-The `listener` value is always defined. The `result` value can be
-set by any middleware. If set to anything other than `ok`, Cowboy
-will not process any subsequent requests on this connection.
-
-The middlewares that come with Cowboy may define or require other
-environment values to perform.
-
-You can update the environment by calling the `cowboy:set_env/3`
-convenience function, adding or replacing a value in the environment.
-
-=== Routing middleware
-
-The routing middleware requires the `dispatch` value. If routing
-succeeds, it will put the handler name and options in the `handler`
-and `handler_opts` values of the environment, respectively.
-
-=== Handler middleware
-
-The handler middleware requires the `handler` and `handler_opts`
-values. It puts the result of the request handling into `result`.

-[appendix]
-== Migrating from Cowboy 1.0 to 2.0
-
-A lot has changed between Cowboy 1.0 and 2.0. The `cowboy_req`
-interface in particular has seen a massive revamp. Hooks are
-gone, their functionality can now be achieved via stream
-handlers.
-
-The documentation has seen great work, in particular the
-manual. Each module and each function now has its own dedicated
-manual page with full details and examples.
-
-=== Compatibility
-
-Compatibility with Erlang/OTP R16, 17 and 18 has been dropped.
-Erlang/OTP 19.0 or above is required. It is non-trivial to
-make Cowboy 2.0 work with older Erlang/OTP versions.
-
-Cowboy 2.0 is not compatible with Cowlib versions older than
-2.0. It should be compatible with Ranch 1.0 or above, however
-it has not been tested with Ranch versions older than 1.4.
-
-Cowboy 2.0 is tested on Arch Linux, Ubuntu, FreeBSD, Windows
-and OSX. It is tested with every point release (latest patch
-release) and also with HiPE on the most recent release.
-
-Cowboy 2.0 now comes with Erlang.mk templates.
-
-=== Features added
-
-* The HTTP/2 protocol is now supported.
-
-* Cowboy no longer uses only one process per connection.
-  It now uses one process per connection plus one process
-  per request by default. This is necessary for HTTP/2.
-  There might be a slight drop in performance for HTTP/1.1
-  connections due to this change.
-
-* Cowboy internals have largely been reworked in order to
-  support HTTP/2. This opened the way to stream handlers,
-  which are a chain of modules that are called whenever
-  something happens relating to a request/response.
-
-* The `cowboy_stream_h` stream handler has been added.
-  It provides most of Cowboy's default behavior.
-
-* The `cowboy_compress_h` stream handler has been added.
-  It compresses responses when possible. It's worth noting
-  that it compresses in more cases than Cowboy 1.0 ever did.
-
-* Because of the many changes in the internals of Cowboy,
-  many options have been added or modified. Of note is that
-  the Websocket options are now given per handler rather
-  than for the entire listener.
-
-* Websocket permessage-deflate compression is now supported
-  via the `compress` option.
-
-* Static file handlers will now correctly find files found
-  in '.ez' archives.
-
-* Constraints have been generalized and are now used not only
-  in the router but also in some `cowboy_req` functions. Their
-  interface has also been modified to allow for reverse
-  operations and formatting of errors.
-
-=== Features removed
-
-* SPDY support has been removed. Use HTTP/2 instead.
-
-* Hooks have been removed. Use xref:streams[stream handlers] instead.
-
-* The undocumented `waiting_stream` hack has been removed.
-  It allowed disabling chunked transfer-encoding for HTTP/1.1.
-  It has no equivalent in Cowboy 2.0. Open a ticket if necessary.
-
-* Sub protocols still exist, but their interface has largely changed
-  and they are no longer documented for the time being.
-
-=== Changed behaviors
-
-* The handler behaviors have been renamed and are now `cowboy_handler`,
-  `cowboy_loop`, `cowboy_rest` and `cowboy_websocket`.
-
-* Plain HTTP, loop, REST and Websocket handlers have had their
-  init and terminate callbacks unified. They now all use the
-  `init/2` and `terminate/3` callbacks. The latter is now optional.
-  The terminate reason has now been documented for all handlers.
-
-* The tuple returned to switch to a different handler type has
-  changed. It now takes the form `{Module, Req, State}` or
-  `{Module, Req, State, Opts}`, where `Opts` is a map of options
-  to configure the handler. The timeout and hibernate options
-  must now be specified using this map, where applicable.
-
-* All behaviors that used to accept `halt` or `shutdown` tuples
-  as a return value no longer do so. The return value is now
-  a `stop` tuple, consistent across Cowboy.
-
-* Middlewares can no longer return an `error` tuple. They have
-  to send the response and return a `stop` tuple instead.
-
-* The `known_content_type` REST handler callback has been removed
-  as it was found unnecessary.
-
-* Websocket handlers have both the normal `init/2` and
-  an optional `websocket_init/1` function. The reason for
-  that exception is that the `websocket_*` callbacks execute
-  in a separate process from the `init/2` callback, and it
-  was therefore not obvious how timers or monitors should
-  be setup properly. They are effectively initializing the
-  handler before and after the HTTP/1.1 upgrade.
-
-* Websocket handlers can now send frames directly from
-  `websocket_init/1`. The frames will be sent immediately
-  after the handshake.
-
-* Websocket handler callbacks no longer receive the Req
-  argument. The `init/2` callback still receives it and
-  can be used to extract relevant information. The `terminate/3`
-  callback, if implemented, may still receive the Req
-  (see next bullet point).
-
-* Websocket handlers have a new `req_filter` option that
-  can be used to customize how much information should be
-  discarded from the Req object after the handshake. Note
-  that the Req object is only available in `terminate/3`
-  past that point.
-
-* Websocket handlers have their timeout default changed
-  from infinity to 60 seconds.
-
-=== New functions
-
-* The `cowboy_req:scheme/1` function has been added.
-
-* The `cowboy_req:uri/1,2` function has been added, replacing the
-  less powerful functions `cowboy_req:url/1` and `cowboy_req:host_url/1`.
-
-* The functions `cowboy_req:match_qs/2` and `cowboy_req:match_cookies/2`
-  allow matching query string and cookies against constraints.
-
-* The function `cowboy_req:set_resp_cookie/3` has been added to
-  complement `cowboy_req:set_resp_cookie/4`.
-
-* The functions `cowboy_req:resp_header/2,3` and `cowboy_req:resp_headers/1`
-  have been added. They can be used to retrieve response headers
-  that were previously set.
-
-* The function `cowboy_req:set_resp_headers/2` has been added. It
-  allows setting many response headers at once.
-
-* The functions `cowboy_req:push/3,4` can be used to push resources
-  for protocols that support it (by default only HTTP/2).
-
-=== Changed functions
-
-* The `cowboy:start_http/4` function was renamed to `cowboy:start_clear/3`.
-
-* The `cowboy:start_https/4` function was renamed to `cowboy:start_tls/3`.
-
-* Most, if not all, functions in the `cowboy_req` module have been modified.
-  Please consult the changelog of each individual functions. The changes
-  are mainly about simplifying and clarifying the interface. The Req is no
-  longer returned when not necessary, maps are used wherever possible,
-  and some functions have been renamed.
-
-* The position of the `Opts` argument for `cowboy_req:set_resp_cookie/4`
-  has changed to improve consistency. It is now the last argument.
-
-=== Removed functions
-
-* The functions `cowboy_req:url/1` and `cowboy_req:host_url/1` have been
-  removed in favor of the new function `cowboy_req:uri/1,2`.
-
-* The functions `cowboy_req:meta/2,3` and `cowboy_req:set_meta/3` have
-  been removed. The Req object is now a public map, therefore they became
-  unnecessary.
-
-* The functions `cowboy_req:set_resp_body_fun/2,3` have been removed.
-  For sending files, the function `cowboy_req:set_resp_body/2` can now
-  take a sendfile tuple.
-
-* Remove many undocumented functions from `cowboy_req`, including the
-  functions `cowboy_req:get/2` and `cowboy_req:set/3`.
-
-=== Other changes
-
-* The correct percent-decoding algorithm is now used for path elements
-  during routing. It will no longer decode `+` characters.
-
-* The router will now properly handle path segments `.` and `..`.
-
-* Routing behavior has changed for URIs containing latin1 characters.
-  They are no longer allowed. URIs are expected to be in UTF-8 once
-  they are percent-decoded.
-
-* Clients that send multiple headers of the same name
-  will have the values of those headers concatenated into a
-  comma-separated list. This is of special importance in the
-  case of the content-type header, as previously only the
-  first value was used in the `content_types_accepted/2` step
-  in REST handlers.
-
-* Etag comparison in REST handlers has been fixed. Some requests may
-  now fail when they succeeded in the past.
-
-* The `If-*-Since` headers are now ignored in REST handlers if
-  the corresponding `If*-Match` header exist. The former is
-  largely a backward compatible header and this shouldn't create
-  any issue. The new behavior follows the current RFCs more closely.
-
-* The static file handler has been improved to handle more special
-  characters on systems that accept them.

-<h1 class="lined-header"><span>Migrating from Cowboy 1.0 to 2.0</span></h1>
-
-<p>A lot has changed between Cowboy 1.0 and 2.0. The <code>cowboy_req</code> interface in particular has seen a massive revamp. Hooks are gone, their functionality can now be achieved via stream handlers.</p>
-<p>The documentation has seen great work, in particular the manual. Each module and each function now has its own dedicated manual page with full details and examples.</p>
-<h2 id="_compatibility">Compatibility</h2>
-<p>Compatibility with Erlang/OTP R16, 17 and 18 has been dropped. Erlang/OTP 19.0 or above is required. It is non-trivial to make Cowboy 2.0 work with older Erlang/OTP versions.</p>
-<p>Cowboy 2.0 is not compatible with Cowlib versions older than 2.0. It should be compatible with Ranch 1.0 or above, however it has not been tested with Ranch versions older than 1.4.</p>
-<p>Cowboy 2.0 is tested on Arch Linux, Ubuntu, FreeBSD, Windows and OSX. It is tested with every point release (latest patch release) and also with HiPE on the most recent release.</p>
-<p>Cowboy 2.0 now comes with Erlang.mk templates.</p>
-<h2 id="_features_added">Features added</h2>
-<ul><li>The HTTP/2 protocol is now supported.
-</li>
-<li>Cowboy no longer uses only one process per connection. It now uses one process per connection plus one process per request by default. This is necessary for HTTP/2. There might be a slight drop in performance for HTTP/1.1 connections due to this change.
-</li>
-<li>Cowboy internals have largely been reworked in order to support HTTP/2. This opened the way to stream handlers, which are a chain of modules that are called whenever something happens relating to a request/response.
-</li>
-<li>The <code>cowboy_stream_h</code> stream handler has been added. It provides most of Cowboy&apos;s default behavior.
-</li>
-<li>The <code>cowboy_compress_h</code> stream handler has been added. It compresses responses when possible. It&apos;s worth noting that it compresses in more cases than Cowboy 1.0 ever did.
-</li>
-<li>Because of the many changes in the internals of Cowboy, many options have been added or modified. Of note is that the Websocket options are now given per handler rather than for the entire listener.
-</li>
-<li>Websocket permessage-deflate compression is now supported via the <code>compress</code> option.
-</li>
-<li>Static file handlers will now correctly find files found in <em>.ez</em> archives.
-</li>
-<li>Constraints have been generalized and are now used not only in the router but also in some <code>cowboy_req</code> functions. Their interface has also been modified to allow for reverse operations and formatting of errors.
-</li>
-</ul>
-<h2 id="_features_removed">Features removed</h2>
-<ul><li>SPDY support has been removed. Use HTTP/2 instead.
-</li>
-<li>Hooks have been removed. Use <a href="../streams">stream handlers</a> instead.
-</li>
-<li>The undocumented <code>waiting_stream</code> hack has been removed. It allowed disabling chunked transfer-encoding for HTTP/1.1. It has no equivalent in Cowboy 2.0. Open a ticket if necessary.
-</li>
-<li>Sub protocols still exist, but their interface has largely changed and they are no longer documented for the time being.
-</li>
-</ul>
-<h2 id="_changed_behaviors">Changed behaviors</h2>
-<ul><li>The handler behaviors have been renamed and are now <code>cowboy_handler</code>, <code>cowboy_loop</code>, <code>cowboy_rest</code> and <code>cowboy_websocket</code>.
-</li>
-<li>Plain HTTP, loop, REST and Websocket handlers have had their init and terminate callbacks unified. They now all use the <code>init/2</code> and <code>terminate/3</code> callbacks. The latter is now optional. The terminate reason has now been documented for all handlers.
-</li>
-<li>The tuple returned to switch to a different handler type has changed. It now takes the form <code>{Module, Req, State}</code> or <code>{Module, Req, State, Opts}</code>, where <code>Opts</code> is a map of options to configure the handler. The timeout and hibernate options must now be specified using this map, where applicable.
-</li>
-<li>All behaviors that used to accept <code>halt</code> or <code>shutdown</code> tuples as a return value no longer do so. The return value is now a <code>stop</code> tuple, consistent across Cowboy.
-</li>
-<li>Middlewares can no longer return an <code>error</code> tuple. They have to send the response and return a <code>stop</code> tuple instead.
-</li>
-<li>The <code>known_content_type</code> REST handler callback has been removed as it was found unnecessary.
-</li>
-<li>Websocket handlers have both the normal <code>init/2</code> and an optional <code>websocket_init/1</code> function. The reason for that exception is that the <code>websocket_*</code> callbacks execute in a separate process from the <code>init/2</code> callback, and it was therefore not obvious how timers or monitors should be setup properly. They are effectively initializing the handler before and after the HTTP/1.1 upgrade.
-</li>
-<li>Websocket handlers can now send frames directly from <code>websocket_init/1</code>. The frames will be sent immediately after the handshake.
-</li>
-<li>Websocket handler callbacks no longer receive the Req argument. The <code>init/2</code> callback still receives it and can be used to extract relevant information. The <code>terminate/3</code> callback, if implemented, may still receive the Req (see next bullet point).
-</li>
-<li>Websocket handlers have a new <code>req_filter</code> option that can be used to customize how much information should be discarded from the Req object after the handshake. Note that the Req object is only available in <code>terminate/3</code> past that point.
-</li>
-<li>Websocket handlers have their timeout default changed from infinity to 60 seconds.
-</li>
-</ul>
-<h2 id="_new_functions">New functions</h2>
-<ul><li>The <code>cowboy_req:scheme/1</code> function has been added.
-</li>
-<li>The <code>cowboy_req:uri/1,2</code> function has been added, replacing the less powerful functions <code>cowboy_req:url/1</code> and <code>cowboy_req:host_url/1</code>.
-</li>
-<li>The functions <code>cowboy_req:match_qs/2</code> and <code>cowboy_req:match_cookies/2</code> allow matching query string and cookies against constraints.
-</li>
-<li>The function <code>cowboy_req:set_resp_cookie/3</code> has been added to complement <code>cowboy_req:set_resp_cookie/4</code>.
-</li>
-<li>The functions <code>cowboy_req:resp_header/2,3</code> and <code>cowboy_req:resp_headers/1</code> have been added. They can be used to retrieve response headers that were previously set.
-</li>
-<li>The function <code>cowboy_req:set_resp_headers/2</code> has been added. It allows setting many response headers at once.
-</li>
-<li>The functions <code>cowboy_req:push/3,4</code> can be used to push resources for protocols that support it (by default only HTTP/2).
-</li>
-</ul>
-<h2 id="_changed_functions">Changed functions</h2>
-<ul><li>The <code>cowboy:start_http/4</code> function was renamed to <code>cowboy:start_clear/3</code>.
-</li>
-<li>The <code>cowboy:start_https/4</code> function was renamed to <code>cowboy:start_tls/3</code>.
-</li>
-<li>Most, if not all, functions in the <code>cowboy_req</code> module have been modified. Please consult the changelog of each individual functions. The changes are mainly about simplifying and clarifying the interface. The Req is no longer returned when not necessary, maps are used wherever possible, and some functions have been renamed.
-</li>
-<li>The position of the <code>Opts</code> argument for <code>cowboy_req:set_resp_cookie/4</code> has changed to improve consistency. It is now the last argument.
-</li>
-</ul>
-<h2 id="_removed_functions">Removed functions</h2>
-<ul><li>The functions <code>cowboy_req:url/1</code> and <code>cowboy_req:host_url/1</code> have been removed in favor of the new function <code>cowboy_req:uri/1,2</code>.
-</li>
-<li>The functions <code>cowboy_req:meta/2,3</code> and <code>cowboy_req:set_meta/3</code> have been removed. The Req object is now a public map, therefore they became unnecessary.
-</li>
-<li>The functions <code>cowboy_req:set_resp_body_fun/2,3</code> have been removed. For sending files, the function <code>cowboy_req:set_resp_body/2</code> can now take a sendfile tuple.
-</li>
-<li>Remove many undocumented functions from <code>cowboy_req</code>, including the functions <code>cowboy_req:get/2</code> and <code>cowboy_req:set/3</code>.
-</li>
-</ul>
-<h2 id="_other_changes">Other changes</h2>
-<ul><li>The correct percent-decoding algorithm is now used for path elements during routing. It will no longer decode <code>+</code> characters.
-</li>
-<li>The router will now properly handle path segments <code>.</code> and <code>..</code>.
-</li>
-<li>Routing behavior has changed for URIs containing latin1 characters. They are no longer allowed. URIs are expected to be in UTF-8 once they are percent-decoded.
-</li>
-<li>Clients that send multiple headers of the same name will have the values of those headers concatenated into a comma-separated list. This is of special importance in the case of the content-type header, as previously only the first value was used in the <code>content_types_accepted/2</code> step in REST handlers.
-</li>
-<li>Etag comparison in REST handlers has been fixed. Some requests may now fail when they succeeded in the past.
-</li>
-<li>The <code>If-*-Since</code> headers are now ignored in REST handlers if the corresponding <code>If*-Match</code> header exist. The former is largely a backward compatible header and this shouldn&apos;t create any issue. The new behavior follows the current RFCs more closely.
-</li>
-<li>The static file handler has been improved to handle more special characters on systems that accept them.
-</li>
-</ul>

-[appendix]
-== Migrating from Cowboy 2.0 to 2.1
-
-Cowboy 2.1 focused on adding features that were temporarily
-removed in Cowboy 2.0. A number of bugs found in the 2.0
-release were also fixed.
-
-=== Features added
-
-* It is now possible to obtain the client TLS certificate
-  and the local IP/port for the connection from the Req object.
-
-* Informational responses (1XX responses) can now be sent.
-  They must be sent before initiating the final response.
-
-* The `expect: 100-continue` header is now handled
-  automatically. The 100 response will be sent on the
-  first `cowboy_req:read_body/2,3,4` call. This only applies
-  when using the default `cowboy_stream_h` stream handler.
-
-=== Experimental features added
-
-Experimental features are previews of features that will be
-added in a future release. They are not documented and their
-interface may change at any time. You are welcome to try them
-and provide feedback.
-
-* The `cowboy_metrics_h` stream handler can be used to
-  extract metrics out of Cowboy. It must be used first in
-  the list of stream handlers, and will record all events
-  related to requests, responses and spawned processes.
-  When the stream terminates it will pass this information
-  to a user-defined callback.
-
-* The `cowboy_tracer_h` stream handler can be used to setup
-  automatic tracing of specific requests. You can conditionally
-  enable tracing based on a function, header, path or any other
-  element from the request and the trace will apply to the
-  entire connection and any processes created by it. This is
-  meant to be used for debugging both in tests and production.
-
-=== Changed behaviors
-
-* The `cowboy_rest` handler now implements a mechanism for
-  switching to a different type of handler from any callback
-  where `stop` is also allowed. Switch by returning
-  `{switch_handler, Module}` or `{switch_handler, Module, Opts}`.
-  This is especially useful for switching to `cowboy_loop`
-  for streaming the request or response body.
-
-* REST callbacks that do not allow `stop` as a return value
-  are now explicitly listed in the documentation.
-
-=== New functions
-
-* The function `cowboy_req:sock/1` returns the IP/port
-  of the local socket.
-
-* The function `cowboy_req:cert/1` returns the client
-  TLS certificate or `undefined` if it isn't available.
-
-* The function `cowboy_req:inform/2,3` sends an
-  informational response.
-
-=== Bugs fixed
-
-* Ensure HTTP/2 connections are not closed prematurely
-  when the user code does not read the request body.
-
-* Ensure HTTP/1.1 streams are not terminated too early.
-  Their behavior is now consistent with the HTTP/2 code
-  where the stream handler is only terminated when the
-  `stop` command is returned.
-
-* Sending zero-sized data from stream handlers or from
-  `cowboy_req:stream_body/3` could lead to issues with
-  HTTP/1.1. This has been fixed.
-
-* The final chunk sent by Cowboy when it terminates a
-  chunked body after the handler process exits was not
-  passed through stream handlers, which could lead to
-  issues when `cowboy_compress_h` was being used. This
-  is now corrected.
-
-* The stream handler state was discarded in some cases
-  where Cowboy had to send a response or response data
-  automatically when ending a stream. This has now
-  been corrected.
-
-* The stream handler callback `terminate/3` will now be
-  called when switching to another protocol using the
-  command `switch_protocol`. This doesn't apply when
-  doing upgrades to HTTP/2 as those occur before the
-  stream is initialized.
-
-* Cowlib has been updated to 2.0.1 to fix an issue with
-  Websocket compression when using Erlang/OTP 20.1. Note
-  that at the time of writing all 20.1 versions (from
-  20.1 to 20.1.4) have issues when compression is enabled.
-  It is expected to work properly from 20.1.5 onward. In
-  the meantime it is recommended to run the plain 20.1
-  release and disable Websocket compression, or use a
-  release before 20.1.
-
-* Cowboy will no longer crash when the `cowboy_clock`
-  process is not running. This can happen when Cowboy
-  is being restarted during upgrades, for example.

-<h1 class="lined-header"><span>Migrating from Cowboy 2.0 to 2.1</span></h1>
-
-<p>Cowboy 2.1 focused on adding features that were temporarily removed in Cowboy 2.0. A number of bugs found in the 2.0 release were also fixed.</p>
-<h2 id="_features_added">Features added</h2>
-<ul><li>It is now possible to obtain the client TLS certificate and the local IP/port for the connection from the Req object.
-</li>
-<li>Informational responses (1XX responses) can now be sent. They must be sent before initiating the final response.
-</li>
-<li>The <code>expect: 100-continue</code> header is now handled automatically. The 100 response will be sent on the first <code>cowboy_req:read_body/2,3,4</code> call. This only applies when using the default <code>cowboy_stream_h</code> stream handler.
-</li>
-</ul>
-<h2 id="_experimental_features_added">Experimental features added</h2>
-<p>Experimental features are previews of features that will be added in a future release. They are not documented and their interface may change at any time. You are welcome to try them and provide feedback.</p>
-<ul><li>The <code>cowboy_metrics_h</code> stream handler can be used to extract metrics out of Cowboy. It must be used first in the list of stream handlers, and will record all events related to requests, responses and spawned processes. When the stream terminates it will pass this information to a user-defined callback.
-</li>
-<li>The <code>cowboy_tracer_h</code> stream handler can be used to setup automatic tracing of specific requests. You can conditionally enable tracing based on a function, header, path or any other element from the request and the trace will apply to the entire connection and any processes created by it. This is meant to be used for debugging both in tests and production.
-</li>
-</ul>
-<h2 id="_changed_behaviors">Changed behaviors</h2>
-<ul><li>The <code>cowboy_rest</code> handler now implements a mechanism for switching to a different type of handler from any callback where <code>stop</code> is also allowed. Switch by returning <code>{switch_handler, Module}</code> or <code>{switch_handler, Module, Opts}</code>. This is especially useful for switching to <code>cowboy_loop</code> for streaming the request or response body.
-</li>
-<li>REST callbacks that do not allow <code>stop</code> as a return value are now explicitly listed in the documentation.
-</li>
-</ul>
-<h2 id="_new_functions">New functions</h2>
-<ul><li>The function <code>cowboy_req:sock/1</code> returns the IP/port of the local socket.
-</li>
-<li>The function <code>cowboy_req:cert/1</code> returns the client TLS certificate or <code>undefined</code> if it isn&apos;t available.
-</li>
-<li>The function <code>cowboy_req:inform/2,3</code> sends an informational response.
-</li>
-</ul>
-<h2 id="_bugs_fixed">Bugs fixed</h2>
-<ul><li>Ensure HTTP/2 connections are not closed prematurely when the user code does not read the request body.
-</li>
-<li>Ensure HTTP/1.1 streams are not terminated too early. Their behavior is now consistent with the HTTP/2 code where the stream handler is only terminated when the <code>stop</code> command is returned.
-</li>
-<li>Sending zero-sized data from stream handlers or from <code>cowboy_req:stream_body/3</code> could lead to issues with HTTP/1.1. This has been fixed.
-</li>
-<li>The final chunk sent by Cowboy when it terminates a chunked body after the handler process exits was not passed through stream handlers, which could lead to issues when <code>cowboy_compress_h</code> was being used. This is now corrected.
-</li>
-<li>The stream handler state was discarded in some cases where Cowboy had to send a response or response data automatically when ending a stream. This has now been corrected.
-</li>
-<li>The stream handler callback <code>terminate/3</code> will now be called when switching to another protocol using the command <code>switch_protocol</code>. This doesn&apos;t apply when doing upgrades to HTTP/2 as those occur before the stream is initialized.
-</li>
-<li>Cowlib has been updated to 2.0.1 to fix an issue with Websocket compression when using Erlang/OTP 20.1. Note that at the time of writing all 20.1 versions (from 20.1 to 20.1.4) have issues when compression is enabled. It is expected to work properly from 20.1.5 onward. In the meantime it is recommended to run the plain 20.1 release and disable Websocket compression, or use a release before 20.1.
-</li>
-<li>Cowboy will no longer crash when the <code>cowboy_clock</code> process is not running. This can happen when Cowboy is being restarted during upgrades, for example.
-</li>
-</ul>

-[[modern_web]]
-== The modern Web
-
-Cowboy is a server for the modern Web. This chapter explains
-what it means and details all the standards involved.
-
-Cowboy supports all the standards listed in this document.
-
-=== HTTP/2
-
-HTTP/2 is the most efficient protocol for consuming Web
-services. It enables clients to keep a connection open
-for long periods of time; to send requests concurrently;
-to reduce the size of requests through HTTP headers
-compression; and more. The protocol is binary, greatly
-reducing the resources needed to parse it.
-
-HTTP/2 also enables the server to push messages to the
-client. This can be used for various purposes, including
-the sending of related resources before the client requests
-them, in an effort to reduce latency. This can also be used
-to enable bidirectional communication.
-
-Cowboy provides transparent support for HTTP/2. Clients
-that know it can use it; others fall back to HTTP/1.1
-automatically.
-
-HTTP/2 is compatible with the HTTP/1.1 semantics.
-
-HTTP/2 is defined by RFC 7540 and RFC 7541.
-
-=== HTTP/1.1
-
-HTTP/1.1 is the previous version of the HTTP protocol.
-The protocol itself is text-based and suffers from numerous
-issues and limitations. In particular it is not possible
-to execute requests concurrently (though pipelining is
-sometimes possible), and it's also sometimes difficult
-to detect that a client disconnected.
-
-HTTP/1.1 does provide very good semantics for interacting
-with Web services. It defines the standard methods, headers
-and status codes used by HTTP/1.1 and HTTP/2 clients and
-servers.
-
-HTTP/1.1 also defines compatibility with an older version
-of the protocol, HTTP/1.0, which was never really standardized
-across implementations.
-
-The core of HTTP/1.1 is defined by RFC 7230, RFC 7231,
-RFC 7232, RFC 7233, RFC 7234 and RFC 7235. Numerous RFCs
-and other specifications exist defining additional HTTP
-methods, status codes, headers or semantics.
-
-=== Websocket
-
-xref:ws_protocol[Websocket] is a protocol built on top of HTTP/1.1
-that provides a two-ways communication channel between the client and
-the server. Communication is asynchronous and can occur concurrently.
-
-It consists of a Javascript object allowing setting up a
-Websocket connection to the server, and a binary based
-protocol for sending data to the server or the client.
-
-Websocket connections can transfer either UTF-8 encoded text
-data or binary data. The protocol also includes support for
-implementing a ping/pong mechanism, allowing the server and
-the client to have more confidence that the connection is still
-alive.
-
-A Websocket connection can be used to transfer any kind of data,
-small or big, text or binary. Because of this Websocket is
-sometimes used for communication between systems.
-
-Websocket messages have no semantics on their own. Websocket
-is closer to TCP in that aspect, and requires you to design
-and implement your own protocol on top of it; or adapt an
-existing protocol to Websocket.
-
-Cowboy provides an interface known as xref:ws_handlers[Websocket handlers]
-that gives complete control over a Websocket connection.
-
-The Websocket protocol is defined by RFC 6455.
-
-=== Long-lived requests
-
-Cowboy provides an interface that can be used to support
-long-polling or to stream large amounts of data reliably,
-including using Server-Sent Events.
-
-Long-polling is a mechanism in which the client performs
-a request which may not be immediately answered by the
-server. It allows clients to request resources that may
-not currently exist, but are expected to be created soon,
-and which will be returned as soon as they are.
-
-Long-polling is essentially a hack, but it is widely used
-to overcome limitations on older clients and servers.
-
-Server-Sent Events is a small protocol defined as a media
-type, `text/event-stream`, along with a new HTTP header,
-`Last-Event-ID`. It is defined in the EventSource W3C
-specification.
-
-Cowboy provides an interface known as xref:loop_handlers[loop handlers]
-that facilitates the implementation of long-polling or stream
-mechanisms. It works regardless of the underlying protocol.
-
-=== REST
-
-xref:rest_principles[REST, or REpresentational State Transfer],
-is a style of architecture for loosely connected distributed
-systems. It can easily be implemented on top of HTTP.
-
-REST is essentially a set of constraints to be followed.
-Many of these constraints are purely architectural and
-solved by simply using HTTP. Some constraints must be
-explicitly followed by the developer.
-
-Cowboy provides an interface known as xref:rest_handlers[REST handlers]
-that simplifies the implementation of a REST API on top of
-the HTTP protocol.

-[[multipart]]
-== Multipart requests
-
-Multipart originates from MIME, an Internet standard that
-extends the format of emails.
-
-A multipart message is a list of parts. A part contains
-headers and a body. The body of the parts may be
-of any media type, and contain text or binary data.
-It is possible for parts to contain a multipart media
-type.
-
-In the context of HTTP, multipart is most often used
-with the `multipart/form-data` media type. It is what
-browsers use to upload files through HTML forms.
-
-The `multipart/byteranges` is also common. It is the
-media type used to send arbitrary bytes from a resource,
-enabling clients to resume downloads.
-
-=== Form-data
-
-In the normal case, when a form is submitted, the
-browser will use the `application/x-www-form-urlencoded`
-content-type. This type is just a list of keys and
-values and is therefore not fit for uploading files.
-
-That's where the `multipart/form-data` content-type
-comes in. When the form is configured to use this
-content-type, the browser will create a multipart
-message where each part corresponds to a field on
-the form. For files, it also adds some metadata in
-the part headers, like the file name.
-
-A form with a text input, a file input and a select
-choice box will result in a multipart message with
-three parts, one for each field.
-
-The browser does its best to determine the media type
-of the files it sends this way, but you should not
-rely on it for determining the contents of the file.
-Proper investigation of the contents is recommended.
-
-=== Checking for multipart messages
-
-The content-type header indicates the presence of
-a multipart message:
-
-[source,erlang]
-----
-{<<"multipart">>, <<"form-data">>, _}
-    = cowboy_req:parse_header(<<"content-type">>, Req).
-----
-
-=== Reading a multipart message
-
-Cowboy provides two sets of functions for reading
-request bodies as multipart messages.
-
-The `cowboy_req:read_part/1,2` functions return the
-next part's headers, if any.
-
-The `cowboy_req:read_part_body/1,2` functions return
-the current part's body. For large bodies you may
-need to call the function multiple times.
-
-To read a multipart message you need to iterate over
-all its parts:
-
-[source,erlang]
-----
-multipart(Req0) ->
-    case cowboy_req:read_part(Req0) of
-        {ok, _Headers, Req1} ->
-            {ok, _Body, Req} = cowboy_req:read_part_body(Req1),
-            multipart(Req);
-        {done, Req} ->
-            Req
-    end.
-----
-
-When part bodies are too large, Cowboy will return
-a `more` tuple, and allow you to loop until the part
-body has been fully read.
-
-The function `cow_multipart:form_data/1` can be used
-to quickly obtain information about a part from a
-`multipart/form-data` message. The function returns
-a `data` or a `file` tuple depending on whether this
-is a normal field or a file being uploaded.
-
-The following snippet will use this function and
-use different strategies depending on whether the
-part is a file:
-
-[source,erlang]
-----
-multipart(Req0) ->
-    case cowboy_req:read_part(Req0) of
-        {ok, Headers, Req1} ->
-            Req = case cow_multipart:form_data(Headers) of
-                {data, _FieldName} ->
-                    {ok, _Body, Req2} = cowboy_req:read_part_body(Req1),
-                    Req2;
-                {file, _FieldName, _Filename, _CType} ->
-                    stream_file(Req1)
-            end,
-            multipart(Req);
-        {done, Req} ->
-            Req
-    end.
-
-stream_file(Req0) ->
-    case cowboy_req:read_part_body(Req0) of
-        {ok, _LastBodyChunk, Req} ->
-            Req;
-        {more, _BodyChunk, Req} ->
-            stream_file(Req)
-    end.
-----
-
-Both the part header and body reading functions can take
-options that will be given to the request body reading
-functions. By default, `cowboy_req:read_part/1` reads
-up to 64KB for up to 5 seconds. `cowboy_req:read_part_body/1`
-has the same defaults as `cowboy_req:read_body/1`.
-
-To change the defaults for part headers:
-
-[source,erlang]
-cowboy_req:read_part(Req, #{length => 128000}).
-
-And for part bodies:
-
-[source,erlang]
-cowboy_req:read_part_body(Req, #{length => 1000000, period => 7000}).
-
-=== Skipping unwanted parts
-
-Part bodies do not have to be read. Cowboy will automatically
-skip it when you request the next part's body.
-
-The following snippet reads all part headers and skips
-all bodies:
-
-[source,erlang]
-----
-multipart(Req0) ->
-    case cowboy_req:read_part(Req0) of
-        {ok, _Headers, Req} ->
-            multipart(Req);
-        {done, Req} ->
-            Req
-    end.
-----
-
-Similarly, if you start reading the body and it ends up
-being too big, you can simply continue with the next part.
-Cowboy will automatically skip what remains.
-
-While Cowboy can skip part bodies automatically, the read
-rate is not configurable. Depending on your application
-you may want to skip manually, in particular if you observe
-poor performance while skipping.
-
-You do not have to read all parts either. You can stop
-reading as soon as you find the data you need.
-
-// @todo Cover the building of multipart messages.

-<p>While Cowboy can skip part bodies automatically, the read rate is not configurable. Depending on your application you may want to skip manually, in particular if you observe poor performance while skipping.</p>
-<p>You do not have to read all parts either. You can stop reading as soon as you find the data you need.</p>

-[[req]]
-== The Req object
-
-The Req object is a variable used for obtaining information
-about a request, read its body or send a response.
-
-It is not really an object in the object-oriented sense.
-It is a simple map that can be directly accessed or
-used when calling functions from the `cowboy_req` module.
-
-The Req object is the subject of a few different chapters.
-In this chapter we will learn about the Req object and
-look at how to retrieve information about the request.
-
-=== Direct access
-
-The Req map contains a number of fields which are documented
-and can be accessed directly. They are the fields that have
-a direct mapping to HTTP: the request `method`; the HTTP
-`version` used; the effective URI components `scheme`,
-`host`, `port`, `path` and `qs`; the request `headers`;
-and the connection `peer` address and port.
-
-Note that the `version` field can be used to determine
-whether a connection is using HTTP/2.
-
-To access a field, you can simply match in the function
-head. The following example sends a simple "Hello world!"
-response when the `method` is GET, and a 405 error
-otherwise.
-
-[source,erlang]
-----
-init(Req0=#{method := <<"GET">>}, State) ->
-    Req = cowboy_req:reply(200, #{
-        <<"content-type">> => <<"text/plain">>
-    }, <<"Hello world!">>, Req0),
-    {ok, Req, State};
-init(Req0, State) ->
-    Req = cowboy_req:reply(405, #{
-        <<"allow">> => <<"GET">>
-    }, Req0),
-    {ok, Req, State}.
-----
-
-Any other field is internal and should not be accessed.
-They may change in future releases, including maintenance
-releases, without notice.
-
-Modifying the Req object, while allowed, is not recommended
-unless strictly necessary. If adding new fields, make sure
-to namespace the field names so that no conflict can occur
-with future Cowboy updates or third party projects.
-
-// @todo There are currently no tests for direct access.
-
-=== Introduction to the cowboy_req interface
-
-// @todo Link to cowboy_req manual
-
-Functions in the `cowboy_req` module provide access to
-the request information but also various operations that
-are common when dealing with HTTP requests.
-
-All the functions that begin with a verb indicate an action.
-Other functions simply return the corresponding value
-(sometimes that value does need to be built, but the
-cost of the operation is equivalent to retrieving a value).
-
-Some of the `cowboy_req` functions return an updated Req
-object. They are the read, reply, set and delete functions.
-While ignoring the returned Req will not cause incorrect
-behavior for some of them, it is highly recommended to
-always keep and use the last returned Req object. The
-manual for `cowboy_req` details these functions and what
-modifications are done to the Req object.
-
-Some of the calls to `cowboy_req` have side effects. This
-is the case of the read and reply functions. Cowboy reads
-the request body or replies immediately when the function
-is called.
-
-All functions will crash if something goes wrong. There
-is usually no need to catch these errors, Cowboy will
-send the appropriate 4xx or 5xx response depending on
-where the crash occurred.
-
-=== Request method
-
-The request method can be retrieved directly:
-
-[source, erlang]
-#{method := Method} = Req.
-
-Or using a function:
-
-[source,erlang]
-Method = cowboy_req:method(Req).
-
-The method is a case sensitive binary string. Standard
-methods include GET, HEAD, OPTIONS, PATCH, POST, PUT
-or DELETE.
-
-=== HTTP version
-
-The HTTP version is informational. It does not indicate that
-the client implements the protocol well or fully.
-
-There is typically no need to change behavior based on the
-HTTP version: Cowboy already does it for you.
-
-It can be useful in some cases, though. For example, one may
-want to redirect HTTP/1.1 clients to use Websocket, while HTTP/2
-clients keep using HTTP/2.
-
-The HTTP version can be retrieved directly:
-
-[source,erlang]
-#{version := Version} = Req.
-
-Or using a function:
-
-[source,erlang]
-Version = cowboy_req:version(Req).
-
-Cowboy defines the `'HTTP/1.0'`, `'HTTP/1.1'` and `'HTTP/2'`
-versions. Custom protocols can define their own values as
-atoms.
-
-=== Effective request URI
-
-The scheme, host, port, path and query string components
-of the effective request URI can all be retrieved directly:
-
-[source,erlang]
-----
-#{
-    scheme := Scheme,
-    host := Host,
-    port := Port,
-    path := Path,
-    qs := Qs
-} = Req.
-----
-
-Or using the related functions:
-
-[source,erlang]
-Scheme = cowboy_req:scheme(Req),
-Host = cowboy_req:host(Req),
-Port = cowboy_req:port(Req),
-Path = cowboy_req:path(Req).
-Qs = cowboy_req:qs(Req).
-
-The scheme and host are lowercased case insensitive binary
-strings. The port is an integer representing the port number.
-The path and query string are case sensitive binary strings.
-
-Cowboy defines only the `<<"http">>` and `<<"https">>` schemes.
-They are chosen so that the scheme will only be `<<"https">>`
-for requests on secure HTTP/1.1 or HTTP/2 connections.
-// @todo Is that tested well?
-
-The effective request URI itself can be reconstructed with
-the `cowboy_req:uri/1,2` function. By default, an absolute
-URI is returned:
-
-[source,erlang]
-%% scheme://host[:port]/path[?qs]
-URI = cowboy_req:uri(Req).
-
-Options are available to either disable or replace some
-or all of the components. Various URIs or URI formats can
-be generated this way, including the origin form:
-
-[source,erlang]
-%% /path[?qs]
-URI = cowboy_req:uri(Req, #{host => undefined}).
-
-The protocol relative form:
-
-[source,erlang]
-%% //host[:port]/path[?qs]
-URI = cowboy_req:uri(Req, #{scheme => undefined}).
-
-The absolute URI without a query string:
-
-[source,erlang]
-URI = cowboy_req:uri(Req, #{qs => undefined}).
-
-A different host:
-
-[source,erlang]
-URI = cowboy_req:uri(Req, #{host => <<"example.org">>}).
-
-And any other combination.
-
-=== Bindings
-
-Bindings are the host and path components that you chose
-to extract when defining the routes of your application.
-They are only available after the routing.
-
-Cowboy provides functions to retrieve one or all bindings.
-
-To retrieve a single value:
-
-[source,erlang]
-Value = cowboy_req:binding(userid, Req).
-
-When attempting to retrieve a value that was not bound,
-`undefined` will be returned. A different default value
-can be provided:
-
-[source,erlang]
-Value = cowboy_req:binding(userid, Req, 42).
-
-To retrieve everything that was bound:
-
-[source,erlang]
-Bindings = cowboy_req:bindings(Req).
-
-They are returned as a map, with keys being atoms.
-
-The Cowboy router also allows you to capture many host
-or path segments at once using the `...` qualifier.
-
-To retrieve the segments captured from the host name:
-
-[source,erlang]
-HostInfo = cowboy_req:host_info(Req).
-
-And the path segments:
-
-[source,erlang]
-PathInfo = cowboy_req:path_info(Req).
-
-Cowboy will return `undefined` if `...` was not used
-in the route.
-
-=== Query parameters
-
-Cowboy provides two functions to access query parameters.
-You can use the first to get the entire list of parameters.
-
-[source,erlang]
-QsVals = cowboy_req:parse_qs(Req),
-{_, Lang} = lists:keyfind(<<"lang">>, 1, QsVals).
-
-Cowboy will only parse the query string, and not do any
-transformation. This function may therefore return duplicates,
-or parameter names without an associated value. The order of
-the list returned is undefined.
-
-When a query string is `key=1&key=2`, the list returned will
-contain two parameters of name `key`.
-
-The same is true when trying to use the PHP-style suffix `[]`.
-When a query string is `key[]=1&key[]=2`, the list returned will
-contain two parameters of name `key[]`.
-
-When a query string is simply `key`, Cowboy will return the
-list `[{<<"key">>, true}]`, using `true` to indicate that the
-parameter `key` was defined, but with no value.
-
-The second function Cowboy provides allows you to match out
-only the parameters you are interested in, and at the same
-time do any post processing you require using xref:constraints[constraints].
-This function returns a map.
-
-[source,erlang]
-#{id := ID, lang := Lang} = cowboy_req:match_qs([id, lang], Req).
-
-Constraints can be applied automatically. The following
-snippet will crash when the `id` parameter is not an integer,
-or when the `lang` parameter is empty. At the same time, the
-value for `id` will be converted to an integer term:
-
-[source,erlang]
-QsMap = cowboy_req:match_qs([{id, int}, {lang, nonempty}], Req).
-
-A default value may also be provided. The default will be used
-if the `lang` key is not found. It will not be used if
-the key is found but has an empty value.
-
-[source,erlang]
-#{lang := Lang} = cowboy_req:match_qs([{lang, [], <<"en-US">>}], Req).
-
-If no default is provided and the value is missing, the
-query string is deemed invalid and the process will crash.
-
-When the query string is `key=1&key=2`, the value for `key`
-will be the list `[1, 2]`. Parameter names do not need to
-include the PHP-style suffix. Constraints may be used to
-ensure that only one value was passed through.
-
-=== Headers
-
-Header values can be retrieved either as a binary string
-or parsed into a more meaningful representation.
-
-The get the raw value:
-
-[source,erlang]
-HeaderVal = cowboy_req:header(<<"content-type">>, Req).
-
-Cowboy expects all header names to be provided as lowercase
-binary strings. This is true for both requests and responses,
-regardless of the underlying protocol.
-
-When the header is missing from the request, `undefined`
-will be returned. A different default can be provided:
-
-[source,erlang]
-HeaderVal = cowboy_req:header(<<"content-type">>, Req, <<"text/plain">>).
-
-All headers can be retrieved at once, either directly:
-
-[source,erlang]
-#{headers := AllHeaders} = Req.
-
-Or using a function:
-
-[source,erlang]
-AllHeaders = cowboy_req:headers(Req).
-
-Cowboy provides equivalent functions to parse individual
-headers. There is no function to parse all headers at once.
-
-To parse a specific header:
-
-[source,erlang]
-ParsedVal = cowboy_req:parse_header(<<"content-type">>, Req).
-
-An exception will be thrown if it doesn't know how to parse the
-given header, or if the value is invalid. The list of known headers
-and default values can be found in the manual.
-
-When the header is missing, `undefined` is returned. You can
-change the default value. Note that it should be the parsed value
-directly:
-
-[source,erlang]
-----
-ParsedVal = cowboy_req:parse_header(<<"content-type">>, Req,
-    {<<"text">>, <<"plain">>, []}).
-----
-
-=== Peer
-
-The peer address and port number for the connection can be
-retrieved either directly or using a function.
-
-To retrieve the peer directly:
-
-[source,erlang]
-#{peer := {IP, Port}} = Req.
-
-And using a function:
-
-[source,erlang]
-{IP, Port} = cowboy_req:peer(Req).
-
-Note that the peer corresponds to the remote end of the
-connection to the server, which may or may not be the
-client itself. It may also be a proxy or a gateway.

-<!-- @todo Link to cowboy_req manual-->
-<p>Functions in the <code>cowboy_req</code> module provide access to the request information but also various operations that are common when dealing with HTTP requests.</p>
-<p>All the functions that begin with a verb indicate an action. Other functions simply return the corresponding value (sometimes that value does need to be built, but the cost of the operation is equivalent to retrieving a value).</p>
-<p>Some of the <code>cowboy_req</code> functions return an updated Req object. They are the read, reply, set and delete functions. While ignoring the returned Req will not cause incorrect behavior for some of them, it is highly recommended to always keep and use the last returned Req object. The manual for <code>cowboy_req</code> details these functions and what modifications are done to the Req object.</p>
-<p>Some of the calls to <code>cowboy_req</code> have side effects. This is the case of the read and reply functions. Cowboy reads the request body or replies immediately when the function is called.</p>
-<p>All functions will crash if something goes wrong. There is usually no need to catch these errors, Cowboy will send the appropriate 4xx or 5xx response depending on where the crash occurred.</p>

-[[req_body]]
-== Reading the request body
-
-The request body can be read using the Req object.
-
-Cowboy will not attempt to read the body until requested.
-You need to call the body reading functions in order to
-retrieve it.
-
-Cowboy will not cache the body, it is therefore only
-possible to read it once.
-
-You are not required to read it, however. If a body is
-present and was not read, Cowboy will either cancel or
-skip its download, depending on the protocol.
-
-Cowboy provides functions for reading the body raw,
-and read and parse form urlencoded or xref:multipart[multipart bodies].
-The latter is covered in its own chapter.
-
-=== Request body presence
-
-Not all requests come with a body. You can check for
-the presence of a request body with this function:
-
-[source,erlang]
-cowboy_req:has_body(Req).
-
-It returns `true` if there is a body; `false` otherwise.
-
-In practice, this function is rarely used. When the
-method is `POST`, `PUT` or `PATCH`, the request body
-is often required by the application, which should
-just attempt to read it directly.
-
-=== Request body length
-
-You can obtain the length of the body:
-
-[source,erlang]
-Length = cowboy_req:body_length(Req).
-
-Note that the length may not be known in advance. In
-that case `undefined` will be returned. This can happen
-with HTTP/1.1's chunked transfer-encoding, or HTTP/2
-when no content-length was provided.
-
-Cowboy will update the body length in the Req object
-once the body has been read completely. A length will
-always be returned when attempting to call this function
-after reading the body completely.
-
-=== Reading the body
-
-You can read the entire body with one function call:
-
-[source,erlang]
-{ok, Data, Req} = cowboy_req:read_body(Req0).
-
-Cowboy returns an `ok` tuple when the body has been
-read fully.
-
-By default, Cowboy will attempt to read up to 8MB
-of data, for up to 15 seconds. The call will return
-once Cowboy has read at least 8MB of data, or at
-the end of the 15 seconds period.
-
-These values can be customized. For example, to read
-only up to 1MB for up to 5 seconds:
-
-[source,erlang]
-----
-{ok, Data, Req} = cowboy_req:read_body(Req0,
-    #{length => 1000000, period => 5000}).
-----
-
-You may also disable the length limit:
-
-[source,erlang]
-{ok, Data, Req} = cowboy_req:read_body(Req0, #{length => infinity}).
-
-This makes the function wait 15 seconds and return with
-whatever arrived during that period. This is not
-recommended for public facing applications.
-
-These two options can effectively be used to control
-the rate of transmission of the request body.
-
-=== Streaming the body
-
-When the body is too large, the first call will return
-a `more` tuple instead of `ok`. You can call the
-function again to read more of the body, reading
-it one chunk at a time.
-
-[source,erlang]
-----
-read_body_to_console(Req0) ->
-    case cowboy_req:read_body(Req0) of
-        {ok, Data, Req} ->
-            io:format("~s", [Data]),
-            Req;
-        {more, Data, Req} ->
-            io:format("~s", [Data]),
-            read_body_to_console(Req)
-    end.
-----
-
-The `length` and `period` options can also be used.
-They need to be passed for every call.
-
-=== Reading a form urlencoded body
-
-Cowboy provides a convenient function for reading and
-parsing bodies sent as application/x-www-form-urlencoded.
-
-[source,erlang]
-{ok, KeyValues, Req} = cowboy_req:read_urlencoded_body(Req0).
-
-This function returns a list of key/values, exactly like
-the function `cowboy_req:parse_qs/1`.
-
-The defaults for this function are different. Cowboy will
-read for up to 64KB and up to 5 seconds. They can be modified:
-
-[source,erlang]
-----
-{ok, KeyValues, Req} = cowboy_req:read_urlencoded_body(Req0,
-    #{length => 4096, period => 3000}).

-== Designing a resource handler
-
-This chapter aims to provide you with a list of questions
-you must answer in order to write a good resource handler.
-It is meant to be usable as a step by step guide.
-
-=== The service
-
-Can the service become unavailable, and when it does, can
-we detect it? For example, database connectivity problems
-may be detected early. We may also have planned outages
-of all or parts of the system. Implement the
-`service_available` callback.
-
-What HTTP methods does the service implement? Do we need
-more than the standard OPTIONS, HEAD, GET, PUT, POST,
-PATCH and DELETE? Are we not using one of those at all?
-Implement the `known_methods` callback.
-
-=== Type of resource handler
-
-Am I writing a handler for a collection of resources,
-or for a single resource?
-
-The semantics for each of these are quite different.
-You should not mix collection and single resource in
-the same handler.
-
-=== Collection handler
-
-Skip this section if you are not doing a collection.
-
-Is the collection hardcoded or dynamic? For example,
-if you use the route `/users` for the collection of
-users then the collection is hardcoded; if you use
-`/forums/:category` for the collection of threads
-then it isn't. When the collection is hardcoded you
-can safely assume the resource always exists.
-
-What methods should I implement?
-
-OPTIONS is used to get some information about the
-collection. It is recommended to allow it even if you
-do not implement it, as Cowboy has a default
-implementation built-in.
-
-HEAD and GET are used to retrieve the collection.
-If you allow GET, also allow HEAD as there's no extra
-work required to make it work.
-
-POST is used to create a new resource inside the
-collection. Creating a resource by using POST on
-the collection is useful when resources may be
-created before knowing their URI, usually because
-parts of it are generated dynamically. A common
-case is some kind of auto incremented integer
-identifier.
-
-The next methods are more rarely allowed.
-
-PUT is used to create a new collection (when
-the collection isn't hardcoded), or replace
-the entire collection.
-
-DELETE is used to delete the entire collection.
-
-PATCH is used to modify the collection using
-instructions given in the request body. A PATCH
-operation is atomic. The PATCH operation may
-be used for such things as reordering; adding,
-modifying or deleting parts of the collection.
-
-=== Single resource handler
-
-Skip this section if you are doing a collection.
-
-What methods should I implement?
-
-OPTIONS is used to get some information about the
-resource. It is recommended to allow it even if you
-do not implement it, as Cowboy has a default
-implementation built-in.
-
-HEAD and GET are used to retrieve the resource.
-If you allow GET, also allow HEAD as there's no extra
-work required to make it work.
-
-POST is used to update the resource.
-
-PUT is used to create a new resource (when it doesn't
-already exist) or replace the resource.
-
-DELETE is used to delete the resource.
-
-PATCH is used to modify the resource using
-instructions given in the request body. A PATCH
-operation is atomic. The PATCH operation may
-be used for adding, removing or modifying specific
-values in the resource.
-
-=== The resource
-
-Following the above discussion, implement the
-`allowed_methods` callback.
-
-Does the resource always exist? If it may not, implement
-the `resource_exists` callback.
-
-Do I need to authenticate the client before they can
-access the resource? What authentication mechanisms
-should I provide? This may include form-based, token-based
-(in the URL or a cookie), HTTP basic, HTTP digest,
-SSL certificate or any other form of authentication.
-Implement the `is_authorized` callback.
-
-Do I need fine-grained access control? How do I determine
-that they are authorized access? Handle that in your
-`is_authorized` callback.
-
-Can access to a resource be forbidden regardless of access
-being authorized? A simple example of that is censorship
-of a resource. Implement the `forbidden` callback.
-
-Are there any constraints on the length of the resource URI?
-For example, the URI may be used as a key in storage and may
-have a limit in length. Implement `uri_too_long`.
-
-=== Representations
-
-What media types do I provide? If text based, what charsets
-are provided? What languages do I provide?
-
-Implement the mandatory `content_types_provided`. Prefix
-the callbacks with `to_` for clarity. For example, `to_html`
-or `to_text`.
-
-Implement the `languages_provided` or `charsets_provided`
-callbacks if applicable.
-
-Is there any other header that may make the representation
-of the resource vary? Implement the `variances` callback.
-
-Depending on your choices for caching content, you may
-want to implement one or more of the `generate_etag`,
-`last_modified` and `expires` callbacks.
-
-Do I want the user or user agent to actively choose a
-representation available? Send a list of available
-representations in the response body and implement
-the `multiple_choices` callback.
-
-=== Redirections
-
-Do I need to keep track of what resources were deleted?
-For example, you may have a mechanism where moving a
-resource leaves a redirect link to its new location.
-Implement the `previously_existed` callback.
-
-Was the resource moved, and is the move temporary? If
-it is explicitly temporary, for example due to maintenance,
-implement the `moved_temporarily` callback. Otherwise,
-implement the `moved_permanently` callback.
-
-=== The request
-
-Do you need to read the query string? Individual headers?
-Implement `malformed_request` and do all the parsing and
-validation in this function. Note that the body should not
-be read at this point.
-
-May there be a request body? Will I know its size?
-What's the maximum size of the request body I'm willing
-to accept? Implement `valid_entity_length`.
-
-Finally, take a look at the sections corresponding to the
-methods you are implementing.
-
-=== OPTIONS method
-
-Cowboy by default will send back a list of allowed methods.
-Do I need to add more information to the response? Implement
-the `options` method.
-
-=== GET and HEAD methods
-
-If you implement the methods GET and/or HEAD, you must
-implement one `ProvideResource` callback for each
-content-type returned by the `content_types_provided`
-callback.
-
-=== PUT, POST and PATCH methods
-
-If you implement the methods PUT, POST and/or PATCH,
-you must implement the `content_types_accepted` callback,
-and one `AcceptCallback` callback for each content-type
-it returns. Prefix the `AcceptCallback` callback names
-with `from_` for clarity. For example, `from_html` or
-`from_json`.
-
-Do we want to allow the POST method to create individual
-resources directly through their URI (like PUT)? Implement
-the `allow_missing_post` callback. It is recommended to
-explicitly use PUT in these cases instead.
-
-May there be conflicts when using PUT to create or replace
-a resource? Do we want to make sure that two updates around
-the same time are not cancelling one another? Implement the
-`is_conflict` callback.
-
-=== DELETE methods
-
-If you implement the method DELETE, you must implement
-the `delete_resource` callback.
-
-When `delete_resource` returns, is the resource completely
-removed from the server, including from any caching service?
-If not, and/or if the deletion is asynchronous and we have
-no way of knowing it has been completed yet, implement the
-`delete_completed` callback.

-== Sending a response
-
-The response must be sent using the Req object.
-
-Cowboy provides two different ways of sending responses:
-either directly or by streaming the body. Response headers
-and body may be set in advance. The response is sent as
-soon as one of the reply or stream reply function is
-called.
-
-Cowboy also provides a simplified interface for sending
-files. It can also send only specific parts of a file.
-
-While only one response is allowed for every request,
-HTTP/2 introduced a mechanism that allows the server
-to push additional resources related to the response.
-This chapter also describes how this feature works in
-Cowboy.
-
-=== Reply
-
-Cowboy provides three functions for sending the entire reply,
-depending on whether you need to set headers and body. In all
-cases, Cowboy will add any headers required by the protocol
-(for example the date header will always be sent).
-
-When you need to set only the status code,
-use `cowboy_req:reply/2`:
-
-[source,erlang]
-Req = cowboy_req:reply(200, Req0).
-
-When you need to set response headers at the same time,
-use `cowboy_req:reply/3`:
-
-[source,erlang]
-----
-Req = cowboy_req:reply(303, #{
-    <<"location">> => <<"https://ninenines.eu">>
-}, Req0).
-----
-
-Note that the header name must always be a lowercase
-binary.
-
-When you also need to set the response body,
-use `cowboy_req:reply/4`:
-
-[source,erlang]
-----
-Req = cowboy_req:reply(200, #{
-    <<"content-type">> => <<"text/plain">>
-}, "Hello world!", Req0).
-----
-
-You should always set the content-type header when the
-response has a body. There is however no need to set
-the content-length header; Cowboy does it automatically.
-
-The response body and the header values must be either
-a binary or an iolist. An iolist is a list containing
-binaries, characters, strings or other iolists. This
-allows you to build a response from different parts
-without having to do any concatenation:
-
-[source,erlang]
-----
-Title = "Hello world!",
-Body = <<"Hats off!">>,
-Req = cowboy_req:reply(200, #{
-    <<"content-type">> => <<"text/html">>
-}, ["<html><head><title>", Title, "</title></head>",
-    "<body><p>", Body, "</p></body></html>"], Req0).
-----
-
-This method of building responses is more efficient than
-concatenating. Behind the scenes, each element of the list
-is simply a pointer, and those pointers are used directly
-when writing to the socket.
-
-=== Stream reply
-
-Cowboy provides two functions for initiating a response,
-and an additional function for streaming the response body.
-Cowboy will add any required headers to the response.
-
-// @todo For HTTP/1.1 Cowboy should probably not use chunked transfer-encoding if the content-length is set.
-
-When you need to set only the status code,
-use `cowboy_req:stream_reply/2`:
-
-[source,erlang]
-----
-Req = cowboy_req:stream_reply(200, Req0),
-
-cowboy_req:stream_body("Hello...", nofin, Req),
-cowboy_req:stream_body("chunked...", nofin, Req),
-cowboy_req:stream_body("world!!", fin, Req).
-----
-
-The second argument to `cowboy_req:stream_body/3` indicates
-whether this data terminates the body. Use `fin` for the
-final flag, and `nofin` otherwise.
-
-This snippet does not set a content-type header. This is
-not recommended. All responses with a body should have
-a content-type. The header can be set beforehand, or
-using the `cowboy_req:stream_reply/3`:
-
-[source,erlang]
-----
-Req = cowboy_req:stream_reply(200, #{
-    <<"content-type">> => <<"text/html">>
-}, Req0),
-
-cowboy_req:stream_body("<html><head>Hello world!</head>", nofin, Req),
-cowboy_req:stream_body("<body><p>Hats off!</p></body></html>", fin, Req).
-----
-
-HTTP provides a few different ways to stream response bodies.
-Cowboy will select the most appropriate one based on the HTTP
-version and the request and response headers.
-
-While not required by any means, it is recommended that you
-set the content-length header in the response if you know it
-in advance. This will ensure that the best response method
-is selected and help clients understand when the response
-is fully received.
-
-// @todo Document trailers here.
-
-=== Preset response headers
-
-Cowboy provides functions to set response headers without
-immediately sending them. They are stored in the Req object
-and sent as part of the response when a reply function is
-called.
-
-To set response headers:
-
-[source,erlang]
-Req = cowboy_req:set_resp_header(<<"allow">>, "GET", Req0).
-
-Header names must be a lowercase binary.
-
-Do not use this function for setting cookies. Refer to
-the xref:cookies[Cookies] chapter for more information.
-
-To check if a response header has already been set:
-
-[source,erlang]
-cowboy_req:has_resp_header(<<"allow">>, Req).
-
-It returns `true` if the header was set, `false` otherwise.
-
-To delete a response header that was set previously:
-
-[source,erlang]
-Req = cowboy_req:delete_resp_header(<<"allow">>, Req0).
-
-=== Overriding headers
-
-As Cowboy provides different ways of setting response
-headers and body, clashes may occur, so it's important
-to understand what happens when a header is set twice.
-
-Headers come from five different origins:
-
-* Protocol-specific headers (for example HTTP/1.1's connection header)
-* Other required headers (for example the date header)
-* Preset headers
-* Headers given to the reply function
-* Set-cookie headers
-
-Cowboy does not allow overriding protocol-specific headers.
-
-Set-cookie headers will always be appended at the end of
-the list of headers before sending the response.
-
-Headers given to the reply function will always override
-preset headers and required headers. If a header is found
-in two or three of these, then the one in the reply function
-is picked and the others are dropped.
-
-Similarly, preset headers will always override required
-headers.
-
-To illustrate, look at the following snippet. Cowboy by
-default sends the server header with the value "Cowboy".
-We can override it:
-
-[source,erlang]
-----
-Req = cowboy_req:reply(200, #{
-    <<"server">> => <<"yaws">>
-}, Req0).
-----
-
-=== Preset response body
-
-Cowboy provides functions to set the response body without
-immediately sending it. It is stored in the Req object and
-sent when the reply function is called.
-
-To set the response body:
-
-[source,erlang]
-Req = cowboy_req:set_resp_body("Hello world!", Req0).
-
-// @todo Yeah we probably should add that function that
-// also sets the content-type at the same time...
-
-To check if a response body has already been set:
-
-[source,erlang]
-cowboy_req:has_resp_body(Req).
-
-It returns `true` if the body was set and is non-empty,
-`false` otherwise.
-
-// @todo We probably should also have a function that
-// properly removes the response body, including any
-// content-* headers.
-
-The preset response body is only sent if the reply function
-used is `cowboy_req:reply/2` or `cowboy_req:reply/3`.
-
-=== Sending files
-
-Cowboy provides a shortcut for sending files. When
-using `cowboy_req:reply/4`, or when presetting the
-response header, you can give a `sendfile` tuple to
-Cowboy:
-
-[source,erlang]
-{sendfile, Offset, Length, Filename}
-
-Depending on the values for `Offset` or `Length`, the
-entire file may be sent, or just a part of it.
-
-The length is required even for sending the entire file.
-Cowboy sends it in the content-length header.
-
-To send a file while replying:
-
-[source,erlang]
-----
-Req = cowboy_req:reply(200, #{
-    <<"content-type">> => "image/png"
-}, {sendfile, 0, 12345, "path/to/logo.png"}, Req0).
-----
-
-// @todo An example of presetting a file would be useful,
-// but let's wait for the function that can set the
-// content-type at the same time.
-
-// @todo What about streaming many files? For example
-// it should be possible to build a tar file on the fly
-// while still using sendfile. Another example could be
-// proper support for multipart byte ranges. Yet another
-// example would be automatic concatenation of CSS or JS
-// files.
-
-=== Informational responses
-
-Cowboy allows you to send informational responses.
-
-Informational responses are responses that have a status
-code between 100 and 199. Any number can be sent before
-the proper response. Sending an informational response
-does not change the behavior of the proper response, and
-clients are expected to ignore any informational response
-they do not understand.
-
-The following snippet sends a 103 informational response
-with some headers that are expected to be in the final
-response.
-
-[source,erlang]
-----
-Req = cowboy_req:inform(103, #{
-    <<"link">> => <<"</style.css>; rel=preload; as=style">>,
-    <<"link">> => <<"</script.js>; rel=preload; as=script">>
-}, Req0).
-----
-
-=== Push
-
-The HTTP/2 protocol introduced the ability to push resources
-related to the one sent in the response. Cowboy provides two
-functions for that purpose: `cowboy_req:push/3,4`.
-
-Push is only available for HTTP/2. Cowboy will automatically
-ignore push requests if the protocol doesn't support it.
-
-The push function must be called before any of the reply
-functions. Doing otherwise will result in a crash.
-
-To push a resource, you need to provide the same information
-as a client performing a request would. This includes the
-HTTP method, the URI and any necessary request headers.
-
-Cowboy by default only requires you to give the path to
-the resource and the request headers. The rest of the URI
-is taken from the current request (excluding the query
-string, set to empty) and the method is GET by default.
-
-The following snippet pushes a CSS file that is linked to
-in the response:
-
-[source,erlang]
-----
-cowboy_req:push("/static/style.css", #{
-    <<"accept">> => <<"text/css">>
-}, Req0),
-Req = cowboy_req:reply(200, #{
-    <<"content-type">> => <<"text/html">>
-}, ["<html><head><title>My web page</title>",
-    "<link rel='stylesheet' type='text/css' href='/static/style.css'>",
-    "<body><p>Welcome to Erlang!</p></body></html>"], Req0).
-----
-
-To override the method, scheme, host, port or query string,
-simply pass in a fourth argument. The following snippet
-uses a different host name:
-
-[source,erlang]
-----
-cowboy_req:push("/static/style.css", #{
-    <<"accept">> => <<"text/css">>
-}, #{host => <<"cdn.example.org">>}, Req),
-----
-
-Pushed resources don't have to be files. As long as the push
-request is cacheable, safe and does not include a body, the
-resource can be pushed.
-
-Under the hood, Cowboy handles pushed requests the same as
-normal requests: a different process is created which will
-ultimately send a response to the client.

-<p>HTTP provides a few different ways to stream response bodies. Cowboy will select the most appropriate one based on the HTTP version and the request and response headers.</p>
-<p>While not required by any means, it is recommended that you set the content-length header in the response if you know it in advance. This will ensure that the best response method is selected and help clients understand when the response is fully received.</p>

-<h2 id="_overriding_headers">Overriding headers</h2>
-<p>As Cowboy provides different ways of setting response headers and body, clashes may occur, so it&apos;s important to understand what happens when a header is set twice.</p>
-<p>Headers come from five different origins:</p>
-<ul><li>Protocol-specific headers (for example HTTP/1.1&apos;s connection header)
-</li>
-<li>Other required headers (for example the date header)
-</li>
-<li>Preset headers
-</li>
-<li>Headers given to the reply function
-</li>
-<li>Set-cookie headers
-</li>
-</ul>
-<p>Cowboy does not allow overriding protocol-specific headers.</p>
-<p>Set-cookie headers will always be appended at the end of the list of headers before sending the response.</p>
-<p>Headers given to the reply function will always override preset headers and required headers. If a header is found in two or three of these, then the one in the reply function is picked and the others are dropped.</p>
-<p>Similarly, preset headers will always override required headers.</p>
-<p>To illustrate, look at the following snippet. Cowboy by default sends the server header with the value &quot;Cowboy&quot;. We can override it:</p>

-<h2 id="_sending_files">Sending files</h2>
-<p>Cowboy provides a shortcut for sending files. When using <code>cowboy_req:reply/4</code>, or when presetting the response header, you can give a <code>sendfile</code> tuple to Cowboy:</p>

-</div></div>
-<p>Depending on the values for <code>Offset</code> or <code>Length</code>, the entire file may be sent, or just a part of it.</p>

-<h2 id="_informational_responses">Informational responses</h2>
-<p>Cowboy allows you to send informational responses.</p>
-<p>Informational responses are responses that have a status code between 100 and 199. Any number can be sent before the proper response. Sending an informational response does not change the behavior of the proper response, and clients are expected to ignore any informational response they do not understand.</p>
-<p>The following snippet sends a 103 informational response with some headers that are expected to be in the final response.</p>

-<h2 id="_push">Push</h2>
-<p>The HTTP/2 protocol introduced the ability to push resources related to the one sent in the response. Cowboy provides two functions for that purpose: <code>cowboy_req:push/3,4</code>.</p>
-<p>Push is only available for HTTP/2. Cowboy will automatically ignore push requests if the protocol doesn&apos;t support it.</p>
-<p>The push function must be called before any of the reply functions. Doing otherwise will result in a crash.</p>
-<p>To push a resource, you need to provide the same information as a client performing a request would. This includes the HTTP method, the URI and any necessary request headers.</p>
-<p>Cowboy by default only requires you to give the path to the resource and the request headers. The rest of the URI is taken from the current request (excluding the query string, set to empty) and the method is GET by default.</p>
-<p>The following snippet pushes a CSS file that is linked to in the response:</p>

-== REST flowcharts
-
-This chapter will explain the REST handler state machine through
-a number of different diagrams.
-
-There are four main paths that requests may follow. One for the
-method OPTIONS; one for the methods GET and HEAD; one for the
-methods PUT, POST and PATCH; and one for the method DELETE.
-
-All paths start with the "Start" diagram, and all paths excluding
-the OPTIONS path go through the "Content negotiation" diagram
-and optionally the "Conditional requests" diagram if the resource
-exists.
-
-The red squares refer to another diagram. The light green squares
-indicate a response. Other squares may be either a callback or a
-question answered by Cowboy itself. Green arrows tend to indicate
-the default behavior if the callback is undefined.
-
-=== Start
-
-All requests start from here.
-
-image::rest_start.png[REST starting flowchart]
-
-A series of callbacks are called in succession to perform
-a general checkup of the service, the request line and
-request headers.
-
-The request body, if any, is not expected to have been
-received for any of these steps. It is only processed
-at the end of the "PUT, POST and PATCH methods" diagram,
-when all conditions have been met.
-
-The `known_methods` and `allowed_methods` callbacks
-return a list of methods. Cowboy then checks if the request
-method is in the list, and stops otherwise.
-
-The `is_authorized` callback may be used to check that
-access to the resource is authorized. Authentication
-may also be performed as needed. When authorization is
-denied, the return value from the callback must include
-a challenge applicable to the requested resource, which
-will be sent back to the client in the www-authenticate
-header.
-
-This diagram is immediately followed by either the
-"OPTIONS method" diagram when the request method is
-OPTIONS, or the "Content negotiation" diagram otherwise.
-
-=== OPTIONS method
-
-This diagram only applies to OPTIONS requests.
-
-image::rest_options.png[REST OPTIONS method flowchart]
-
-The `options` callback may be used to add information
-about the resource, such as media types or languages
-provided; allowed methods; any extra information. A
-response body may also be set, although clients should
-not be expected to read it.
-
-If the `options` callback is not defined, Cowboy will
-send a response containing the list of allowed methods
-by default.
-
-=== Content negotiation
-
-This diagram applies to all request methods other than
-OPTIONS. It is executed right after the "Start" diagram
-is completed.
-
-image::rest_conneg.png[REST content negotiation flowchart]
-
-The purpose of these steps is to determine an appropriate
-representation to be sent back to the client.
-
-The request may contain any of the accept header; the
-accept-language header; or the accept-charset header.
-When present, Cowboy will parse the headers and then
-call the corresponding callback to obtain the list
-of provided content-type, language or charset for this
-resource. It then automatically select the best match
-based on the request.
-
-If a callback is not defined, Cowboy will select the
-content-type, language or charset that the client
-prefers.
-
-The `content_types_provided` also returns the name of
-a callback for every content-type it accepts. This
-callback will only be called at the end of the
-"GET and HEAD methods" diagram, when all conditions
-have been met.
-
-The selected content-type, language and charset are
-saved as meta values in the Req object. You *should*
-use the appropriate representation if you set a
-response body manually (alongside an error code,
-for example).
-
-This diagram is immediately followed by
-the "GET and HEAD methods" diagram,
-the "PUT, POST and PATCH methods" diagram,
-or the "DELETE method" diagram, depending on the
-method.
-
-=== GET and HEAD methods
-
-This diagram only applies to GET and HEAD requests.
-
-For a description of the `cond` step, please see
-the "Conditional requests" diagram.
-
-image::rest_get_head.png[REST GET/HEAD methods flowchart]
-
-When the resource exists, and the conditional steps
-succeed, the resource can be retrieved.
-
-Cowboy prepares the response by first retrieving
-metadata about the representation, then by calling
-the `ProvideResource` callback. This is the callback
-you defined for each content-types you returned from
-`content_types_provided`. This callback returns the body
-that will be sent back to the client, or a fun if the
-body must be streamed.
-
-When the resource does not exist, Cowboy will figure out
-whether the resource existed previously, and if so whether
-it was moved elsewhere in order to redirect the client to
-the new URI.
-
-The `moved_permanently` and `moved_temporarily` callbacks
-must return the new location of the resource if it was in
-fact moved.
-
-=== PUT, POST and PATCH methods
-
-This diagram only applies to PUT, POST and PATCH requests.
-
-For a description of the `cond` step, please see
-the "Conditional requests" diagram.
-
-image::rest_put_post_patch.png[REST PUT/POST/PATCH methods flowchart]
-
-When the resource exists, first the conditional steps
-are executed. When that succeeds, and the method is PUT,
-Cowboy will call the `is_conflict` callback. This function
-can be used to prevent potential race conditions, by locking
-the resource for example.
-
-Then all three methods reach the `content_types_accepted`
-step that we will describe in a few paragraphs.
-
-When the resource does not exist, and the method is PUT,
-Cowboy will check for conflicts and then move on to the
-`content_types_accepted` step. For other methods, Cowboy
-will figure out whether the resource existed previously,
-and if so whether it was moved elsewhere. If the resource
-is truly non-existent, the method is POST and the call
-for `allow_missing_post` returns `true`, then Cowboy will
-move on to the `content_types_accepted` step. Otherwise
-the request processing ends there.
-
-The `moved_permanently` and `moved_temporarily` callbacks
-must return the new location of the resource if it was in
-fact moved.
-
-The `content_types_accepted` returns a list of
-content-types it accepts, but also the name of a callback
-for each of them. Cowboy will select the appropriate
-callback for processing the request body and call it.
-
-This callback may return one of three different return
-values.
-
-If an error occurred while processing the request body,
-it must return `false` and Cowboy will send an
-appropriate error response.
-
-If the method is POST, then you may return `true` with
-an URI of where the resource has been created. This is
-especially useful for writing handlers for collections.
-
-Otherwise, return `true` to indicate success. Cowboy
-will select the appropriate response to be sent depending
-on whether a resource has been created, rather than
-modified, and on the availability of a location header
-or a body in the response.
-
-=== DELETE method
-
-This diagram only applies to DELETE requests.
-
-For a description of the `cond` step, please see
-the "Conditional requests" diagram.
-
-image::rest_delete.png[REST DELETE method flowchart]
-
-When the resource exists, and the conditional steps
-succeed, the resource can be deleted.
-
-Deleting the resource is a two steps process. First
-the callback `delete_resource` is executed. Use this
-callback to delete the resource.
-
-Because the resource may be cached, you must also
-delete all cached representations of this resource
-in the system. This operation may take a while though,
-so you may return before it finished.
-
-Cowboy will then call the `delete_completed` callback.
-If you know that the resource has been completely
-deleted from your system, including from caches, then
-you can return `true`. If any doubts persist, return
-`false`. Cowboy will assume `true` by default.
-
-To finish, Cowboy checks if you set a response body,
-and depending on that, sends the appropriate response.
-
-When the resource does not exist, Cowboy will figure out
-whether the resource existed previously, and if so whether
-it was moved elsewhere in order to redirect the client to
-the new URI.
-
-The `moved_permanently` and `moved_temporarily` callbacks
-must return the new location of the resource if it was in
-fact moved.
-
-=== Conditional requests
-
-This diagram applies to all request methods other than
-OPTIONS. It is executed right after the `resource_exists`
-callback, when the resource exists.
-
-image::rest_cond.png[REST conditional requests flowchart]
-
-A request becomes conditional when it includes either of
-the if-match header; the if-unmodified-since header; the
-if-none-match header; or the if-modified-since header.
-
-If the condition fails, the request ends immediately
-without any retrieval or modification of the resource.
-
-The `generate_etag` and `last_modified` are called as
-needed. Cowboy will only call them once and then cache
-the results for subsequent use.

-<p>This chapter will explain the REST handler state machine through a number of different diagrams.</p>
-<p>There are four main paths that requests may follow. One for the method OPTIONS; one for the methods GET and HEAD; one for the methods PUT, POST and PATCH; and one for the method DELETE.</p>
-<p>All paths start with the &quot;Start&quot; diagram, and all paths excluding the OPTIONS path go through the &quot;Content negotiation&quot; diagram and optionally the &quot;Conditional requests&quot; diagram if the resource exists.</p>
-<p>The red squares refer to another diagram. The light green squares indicate a response. Other squares may be either a callback or a question answered by Cowboy itself. Green arrows tend to indicate the default behavior if the callback is undefined.</p>
-<h2 id="_start">Start</h2>
-<p>All requests start from here.</p>
-<img src="../rest_start.png" alt="REST starting flowchart"/><p>A series of callbacks are called in succession to perform a general checkup of the service, the request line and request headers.</p>
-<p>The request body, if any, is not expected to have been received for any of these steps. It is only processed at the end of the &quot;PUT, POST and PATCH methods&quot; diagram, when all conditions have been met.</p>
-<p>The <code>known_methods</code> and <code>allowed_methods</code> callbacks return a list of methods. Cowboy then checks if the request method is in the list, and stops otherwise.</p>
-<p>The <code>is_authorized</code> callback may be used to check that access to the resource is authorized. Authentication may also be performed as needed. When authorization is denied, the return value from the callback must include a challenge applicable to the requested resource, which will be sent back to the client in the www-authenticate header.</p>
-<p>This diagram is immediately followed by either the &quot;OPTIONS method&quot; diagram when the request method is OPTIONS, or the &quot;Content negotiation&quot; diagram otherwise.</p>
-<h2 id="_options_method">OPTIONS method</h2>
-<p>This diagram only applies to OPTIONS requests.</p>
-<img src="../rest_options.png" alt="REST OPTIONS method flowchart"/><p>The <code>options</code> callback may be used to add information about the resource, such as media types or languages provided; allowed methods; any extra information. A response body may also be set, although clients should not be expected to read it.</p>
-<p>If the <code>options</code> callback is not defined, Cowboy will send a response containing the list of allowed methods by default.</p>
-<h2 id="_content_negotiation">Content negotiation</h2>
-<p>This diagram applies to all request methods other than OPTIONS. It is executed right after the &quot;Start&quot; diagram is completed.</p>
-<img src="../rest_conneg.png" alt="REST content negotiation flowchart"/><p>The purpose of these steps is to determine an appropriate representation to be sent back to the client.</p>
-<p>The request may contain any of the accept header; the accept-language header; or the accept-charset header. When present, Cowboy will parse the headers and then call the corresponding callback to obtain the list of provided content-type, language or charset for this resource. It then automatically select the best match based on the request.</p>
-<p>If a callback is not defined, Cowboy will select the content-type, language or charset that the client prefers.</p>
-<p>The <code>content_types_provided</code> also returns the name of a callback for every content-type it accepts. This callback will only be called at the end of the &quot;GET and HEAD methods&quot; diagram, when all conditions have been met.</p>
-<p>The selected content-type, language and charset are saved as meta values in the Req object. You <strong>should</strong> use the appropriate representation if you set a response body manually (alongside an error code, for example).</p>
-<p>This diagram is immediately followed by the &quot;GET and HEAD methods&quot; diagram, the &quot;PUT, POST and PATCH methods&quot; diagram, or the &quot;DELETE method&quot; diagram, depending on the method.</p>
-<h2 id="_get_and_head_methods">GET and HEAD methods</h2>
-<p>This diagram only applies to GET and HEAD requests.</p>
-<p>For a description of the <code>cond</code> step, please see the &quot;Conditional requests&quot; diagram.</p>

-[[rest_handlers]]
-== REST handlers
-
-REST is implemented in Cowboy as a sub protocol. The request
-is handled as a state machine with many optional callbacks
-describing the resource and modifying the machine's behavior.
-
-The REST handler is the recommended way to handle HTTP requests.
-
-=== Initialization
-
-First, the `init/2` callback is called. This callback is common
-to all handlers. To use REST for the current request, this function
-must return a `cowboy_rest` tuple.
-
-[source,erlang]
-----
-init(Req, State) ->
-    {cowboy_rest, Req, State}.
-----
-
-Cowboy will then switch to the REST protocol and start executing
-the state machine.
-
-After reaching the end of the flowchart, the `terminate/3` callback
-will be called if it is defined.
-
-=== Methods
-
-The REST component has code for handling the following HTTP methods:
-HEAD, GET, POST, PATCH, PUT, DELETE and OPTIONS.
-
-Other methods can be accepted, however they have no specific callback
-defined for them at this time.
-
-=== Callbacks
-
-All callbacks are optional. Some may become mandatory depending
-on what other defined callbacks return. The various flowcharts
-in the next chapter should be a useful to determine which callbacks
-you need.
-
-All callbacks take two arguments, the Req object and the State,
-and return a three-element tuple of the form `{Value, Req, State}`.
-
-Nearly all callbacks can also return `{stop, Req, State}` to
-stop execution of the request, and
-`{{switch_handler, Module}, Req, State}` or
-`{{switch_handler, Module, Opts}, Req, State}` to switch to
-a different handler type. The exceptions are `expires`
-`generate_etag`, `last_modified` and `variances`.
-
-The following table summarizes the callbacks and their default values.
-If the callback isn't defined, then the default value will be used.
-Please look at the flowcharts to find out the result of each return
-value.
-
-In the following table, "skip" means the callback is entirely skipped
-if it is undefined, moving directly to the next step. Similarly,
-"none" means there is no default value for this callback.
-
-[cols="<,^",options="header"]
-|===
-| Callback name          | Default value
-| allowed_methods        | `[<<"GET">>, <<"HEAD">>, <<"OPTIONS">>]`
-| allow_missing_post     | `true`
-| charsets_provided      | skip
-| content_types_accepted | none
-// @todo Space required for the time being: https://github.com/spf13/hugo/issues/2398
-| content_types_provided | `[{{ <<"text">>, <<"html">>, '*'}, to_html}]`
-| delete_completed       | `true`
-| delete_resource        | `false`
-| expires                | `undefined`
-| forbidden              | `false`
-| generate_etag          | `undefined`
-| is_authorized          | `true`
-| is_conflict            | `false`
-| known_methods          | `[<<"GET">>, <<"HEAD">>, <<"POST">>, <<"PUT">>, <<"PATCH">>, <<"DELETE">>, <<"OPTIONS">>]`
-| languages_provided     | skip
-| last_modified          | `undefined`
-| malformed_request      | `false`
-| moved_permanently      | `false`
-| moved_temporarily      | `false`
-| multiple_choices       | `false`
-| options                | `ok`
-| previously_existed     | `false`
-| resource_exists        | `true`
-| service_available      | `true`
-| uri_too_long           | `false`
-| valid_content_headers  | `true`
-| valid_entity_length    | `true`
-| variances              | `[]`
-|===
-
-As you can see, Cowboy tries to move on with the request whenever
-possible by using well thought out default values.
-
-In addition to these, there can be any number of user-defined
-callbacks that are specified through `content_types_accepted/2`
-and `content_types_provided/2`. They can take any name, however
-it is recommended to use a separate prefix for the callbacks of
-each function. For example, `from_html` and `to_html` indicate
-in the first case that we're accepting a resource given as HTML,
-and in the second case that we send one as HTML.
-
-=== Meta data
-
-Cowboy will set informative values to the Req object at various
-points of the execution. You can retrieve them by matching the
-Req object directly. The values are defined in the following table:
-
-[cols="<,<",options="header"]
-|===
-| Key        | Details
-| media_type | The content-type negotiated for the response entity.
-| language   | The language negotiated for the response entity.
-| charset    | The charset negotiated for the response entity.
-|===
-
-They can be used to send a proper body with the response to a
-request that used a method other than HEAD or GET.
-
-=== Response headers
-
-Cowboy will set response headers automatically over the execution
-of the REST code. They are listed in the following table.
-
-[cols="<,<",options="header"]
-|===
-| Header name      | Details
-| content-language | Language used in the response body
-| content-type     | Media type and charset of the response body
-| etag             | Etag of the resource
-| expires          | Expiration date of the resource
-| last-modified    | Last modification date for the resource
-| location         | Relative or absolute URI to the requested resource
-| vary             | List of headers that may change the representation of the resource

-== REST principles
-
-This chapter will attempt to define the concepts behind REST
-and explain what makes a service RESTful.
-
-REST is often confused with performing a distinct operation
-depending on the HTTP method, while using more than the GET
-and POST methods. That's highly misguided at best.
-
-We will first attempt to define REST and will look at what
-it means in the context of HTTP and the Web.
-For a more in-depth explanation of REST, you can read
-http://www.ics.uci.edu/~fielding/pubs/dissertation/top.htm[Roy T. Fielding's dissertation]
-as it does a great job explaining where it comes from and
-what it achieves.
-
-=== REST architecture
-
-REST is a *client-server* architecture. The client and the server
-both have a different set of concerns. The server stores and/or
-manipulates information and makes it available to the user in
-an efficient manner. The client takes that information and
-displays it to the user and/or uses it to perform subsequent
-requests for information. This separation of concerns allows both
-the client and the server to evolve independently as it only
-requires that the interface stays the same.
-
-REST is *stateless*. That means the communication between the
-client and the server always contains all the information needed
-to perform the request. There is no session state in the server,
-it is kept entirely on the client's side. If access to a resource
-requires authentication, then the client needs to authenticate
-itself with every request.
-
-REST is *cacheable*. The client, the server and any intermediary
-components can all cache resources in order to improve performance.
-
-REST provides a *uniform interface* between components. This
-simplifies the architecture, as all components follow the same
-rules to speak to one another. It also makes it easier to understand
-the interactions between the different components of the system.
-A number of constraints are required to achieve this. They are
-covered in the rest of the chapter.
-
-REST is a *layered system*. Individual components cannot see
-beyond the immediate layer with which they are interacting. This
-means that a client connecting to an intermediate component, like
-a proxy, has no knowledge of what lies beyond. This allows
-components to be independent and thus easily replaceable or
-extendable.
-
-REST optionally provides *code on demand*. Code may be downloaded
-to extend client functionality. This is optional however because
-the client may not be able to download or run this code, and so
-a REST component cannot rely on it being executed.
-
-=== Resources and resource identifiers
-
-A resource is an abstract concept. In a REST system, any information
-that can be named may be a resource. This includes documents, images,
-a collection of resources and any other information. Any information
-that can be the target of an hypertext link can be a resource.
-
-A resource is a conceptual mapping to a set of entities. The set of
-entities evolves over time; a resource doesn't. For example, a resource
-can map to "users who have logged in this past month" and another
-to "all users". At some point in time they may map to the same set of
-entities, because all users logged in this past month. But they are
-still different resources. Similarly, if nobody logged in recently,
-then the first resource may map to the empty set. This resource exists
-regardless of the information it maps to.
-
-Resources are identified by uniform resource identifiers, also known
-as URIs. Sometimes internationalized resource identifiers, or IRIs,
-may also be used, but these can be directly translated into a URI.
-
-In practice we will identify two kinds of resources. Individual
-resources map to a set of one element, for example "user Joe".
-Collection of resources map to a set of 0 to N elements,
-for example "all users".
-
-=== Resource representations
-
-The representation of a resource is a sequence of bytes associated
-with metadata.
-
-The metadata comes as a list of key-value pairs, where the name
-corresponds to a standard that defines the value's structure and
-semantics. With HTTP, the metadata comes in the form of request
-or response headers. The headers' structure and semantics are well
-defined in the HTTP standard. Metadata includes representation
-metadata, resource metadata and control data.
-
-The representation metadata gives information about the
-representation, such as its media type, the date of last
-modification, or even a checksum.
-
-Resource metadata could be link to related resources or
-information about additional representations of the resource.
-
-Control data allows parameterizing the request or response.
-For example, we may only want the representation returned if
-it is more recent than the one we have in cache. Similarly,
-we may want to instruct the client about how it should cache
-the representation. This isn't restricted to caching. We may,
-for example, want to store a new representation of a resource
-only if it wasn't modified since we first retrieved it.
-
-The data format of a representation is also known as the media
-type. Some media types are intended for direct rendering to the
-user, while others are intended for automated processing. The
-media type is a key component of the REST architecture.
-
-=== Self-descriptive messages
-
-Messages must be self-descriptive. That means that the data
-format of a representation must always come with its media
-type (and similarly requesting a resource involves choosing
-the media type of the representation returned). If you are
-sending HTML, then you must say it is HTML by sending the
-media type with the representation. In HTTP this is done
-using the content-type header.
-
-The media type is often an IANA registered media type, like
-`text/html` or `image/png`, but does not need to be. Exactly
-two things are important for respecting this constraint: that
-the media type is well specified, and that the sender and
-recipient agree about what the media type refers to.
-
-This means that you can create your own media types, like
-`application/x-mine`, and that as long as you write the
-specifications for it and that both endpoints agree about
-it then the constraint is respected.
-
-=== Hypermedia as the engine of application state
-
-The last constraint is generally where services that claim
-to be RESTful fail. Interactions with a server must be
-entirely driven by hypermedia. The client does not need
-any prior knowledge of the service in order to use it,
-other than an entry point and of course basic understanding
-of the media type of the representations, at the very least
-enough to find and identify hyperlinks and link relations.
-
-To give a simple example, if your service only works with
-the `application/json` media type then this constraint
-cannot be respected (as there are no concept of links in
-JSON) and thus your service isn't RESTful. This is the case
-for the majority of self-proclaimed REST services.
-
-On the other hand if you create a JSON based media type
-that has a concept of links and link relations, then
-your service might be RESTful.
-
-Respecting this constraint means that the entirety of the
-service becomes self-discoverable, not only the resources
-in it, but also the operations you can perform on it. This
-makes clients very thin as there is no need to implement
-anything specific to the service to operate on it.

-[[routing]]
-== Routing
-
-Cowboy does nothing by default.
-
-To make Cowboy useful, you need to map URIs to Erlang modules that will
-handle the requests. This is called routing.
-
-When Cowboy receives a request, it tries to match the requested host and
-path to the configured routes. When there's a match, the route's
-associated handler is executed.
-
-Routes need to be compiled before they can be used by Cowboy.
-The result of the compilation is the dispatch rules.
-
-=== Syntax
-
-The general structure for the routes is defined as follow.
-
-[source,erlang]
-Routes = [Host1, Host2, ... HostN].
-
-Each host contains matching rules for the host along with optional
-constraints, and a list of routes for the path component.
-
-[source,erlang]
-Host1 = {HostMatch, PathsList}.
-Host2 = {HostMatch, Constraints, PathsList}.
-
-The list of routes for the path component is defined similar to the
-list of hosts.
-
-[source,erlang]
-PathsList = [Path1, Path2, ... PathN].
-
-Finally, each path contains matching rules for the path along with
-optional constraints, and gives us the handler module to be used
-along with its initial state.
-
-[source,erlang]
-Path1 = {PathMatch, Handler, InitialState}.
-Path2 = {PathMatch, Constraints, Handler, InitialState}.
-
-Continue reading to learn more about the match syntax and the optional
-constraints.
-
-=== Match syntax
-
-The match syntax is used to associate host names and paths with their
-respective handlers.
-
-The match syntax is the same for host and path with a few subtleties.
-Indeed, the segments separator is different, and the host is matched
-starting from the last segment going to the first. All examples will
-feature both host and path match rules and explain the differences
-when encountered.
-
-Excluding special values that we will explain at the end of this section,
-the simplest match value is a host or a path. It can be given as either
-a `string()` or a `binary()`.
-
-[source,erlang]
-----
-PathMatch1 = "/".
-PathMatch2 = "/path/to/resource".
-
-HostMatch1 = "cowboy.example.org".
-----
-
-As you can see, all paths defined this way must start with a slash
-character. Note that these two paths are identical as far as routing
-is concerned.
-
-[source,erlang]
-PathMatch2 = "/path/to/resource".
-PathMatch3 = "/path/to/resource/".
-
-Hosts with and without a trailing dot are equivalent for routing.
-Similarly, hosts with and without a leading dot are also equivalent.
-
-[source,erlang]
-HostMatch1 = "cowboy.example.org".
-HostMatch2 = "cowboy.example.org.".
-HostMatch3 = ".cowboy.example.org".
-
-It is possible to extract segments of the host and path and to store
-the values in the `Req` object for later use. We call these kind of
-values bindings.
-
-The syntax for bindings is very simple. A segment that begins with
-the `:` character means that what follows until the end of the segment
-is the name of the binding in which the segment value will be stored.
-
-[source,erlang]
-PathMatch = "/hats/:name/prices".
-HostMatch = ":subdomain.example.org".
-
-If these two end up matching when routing, you will end up with two
-bindings defined, `subdomain` and `name`, each containing the
-segment value where they were defined. For example, the URL
-`http://test.example.org/hats/wild_cowboy_legendary/prices` will
-result in having the value `test` bound to the name `subdomain`
-and the value `wild_cowboy_legendary` bound to the name `name`.
-They can later be retrieved using `cowboy_req:binding/{2,3}`. The
-binding name must be given as an atom.
-
-There is a special binding name you can use to mimic the underscore
-variable in Erlang. Any match against the `_` binding will succeed
-but the data will be discarded. This is especially useful for
-matching against many domain names in one go.
-
-[source,erlang]
-HostMatch = "ninenines.:_".
-
-Similarly, it is possible to have optional segments. Anything
-between brackets is optional.
-
-[source,erlang]
-PathMatch = "/hats/[page/:number]".
-HostMatch = "[www.]ninenines.eu".
-
-You can also have imbricated optional segments.
-
-[source,erlang]
-PathMatch = "/hats/[page/[:number]]".
-
-You can retrieve the rest of the host or path using `[...]`.
-In the case of hosts it will match anything before, in the case
-of paths anything after the previously matched segments. It is
-a special case of optional segments, in that it can have
-zero, one or many segments. You can then find the segments using
-`cowboy_req:host_info/1` and `cowboy_req:path_info/1` respectively.
-They will be represented as a list of segments.
-
-[source,erlang]
-PathMatch = "/hats/[...]".
-HostMatch = "[...]ninenines.eu".
-
-If a binding appears twice in the routing rules, then the match
-will succeed only if they share the same value. This copies the
-Erlang pattern matching behavior.
-
-[source,erlang]
-PathMatch = "/hats/:name/:name".
-
-This is also true when an optional segment is present. In this
-case the two values must be identical only if the segment is
-available.
-
-[source,erlang]
-PathMatch = "/hats/:name/[:name]".
-
-If a binding is defined in both the host and path, then they must
-also share the same value.
-
-[source,erlang]
-PathMatch = "/:user/[...]".
-HostMatch = ":user.github.com".
-
-Finally, there are two special match values that can be used. The
-first is the atom `'_'` which will match any host or path.
-
-[source,erlang]
-PathMatch = '_'.
-HostMatch = '_'.
-
-The second is the special host match `"*"` which will match the
-wildcard path, generally used alongside the `OPTIONS` method.
-
-[source,erlang]
-HostMatch = "*".
-
-=== Constraints
-
-After the matching has completed, the resulting bindings can be tested
-against a set of constraints. Constraints are only tested when the
-binding is defined. They run in the order you defined them. The match
-will succeed only if they all succeed. If the match fails, then Cowboy
-tries the next route in the list.
-
-The format used for constraints is the same as match functions in
-`cowboy_req`: they are provided as a list of fields which may have
-one or more constraints. While the router accepts the same format,
-it will skip fields with no constraints and will also ignore default
-values, if any.
-
-Read more about xref:constraints[constraints].
-
-=== Compilation
-
-The routes must be compiled before Cowboy can use them. The compilation
-step normalizes the routes to simplify the code and speed up the
-execution, but the routes are still looked up one by one in the end.
-Faster compilation strategies could be to compile the routes directly
-to Erlang code, but would require heavier dependencies.
-
-To compile routes, just call the appropriate function:
-
-[source,erlang]
-----
-Dispatch = cowboy_router:compile([
-    %% {HostMatch, list({PathMatch, Handler, InitialState})}
-    {'_', [{'_', my_handler, #{}}]}
-]),
-%% Name, NbAcceptors, TransOpts, ProtoOpts
-cowboy:start_clear(my_http_listener,
-    [{port, 8080}],
-    #{env => #{dispatch => Dispatch}}
-).
-----
-
-=== Live update
-
-You can use the `cowboy:set_env/3` function for updating the dispatch
-list used by routing. This will apply to all new connections accepted
-by the listener:
-
-[source,erlang]
-Dispatch = cowboy_router:compile(Routes),
-cowboy:set_env(my_http_listener, dispatch, Dispatch).
-
-Note that you need to compile the routes again before updating.

-<p>It is possible to extract segments of the host and path and to store the values in the <code>Req</code> object for later use. We call these kind of values bindings.</p>
-<p>The syntax for bindings is very simple. A segment that begins with the <code>:</code> character means that what follows until the end of the segment is the name of the binding in which the segment value will be stored.</p>

-</div></div>
-<p>If these two end up matching when routing, you will end up with two bindings defined, <code>subdomain</code> and <code>name</code>, each containing the segment value where they were defined. For example, the URL <code>http://test.example.org/hats/wild_cowboy_legendary/prices</code> will result in having the value <code>test</code> bound to the name <code>subdomain</code> and the value <code>wild_cowboy_legendary</code> bound to the name <code>name</code>. They can later be retrieved using <code>cowboy_req:binding/{2,3}</code>. The binding name must be given as an atom.</p>
-<p>There is a special binding name you can use to mimic the underscore variable in Erlang. Any match against the <code>_</code> binding will succeed but the data will be discarded. This is especially useful for matching against many domain names in one go.</p>

-<p>You can retrieve the rest of the host or path using <code>[...]</code>. In the case of hosts it will match anything before, in the case of paths anything after the previously matched segments. It is a special case of optional segments, in that it can have zero, one or many segments. You can then find the segments using <code>cowboy_req:host_info/1</code> and <code>cowboy_req:path_info/1</code> respectively. They will be represented as a list of segments.</p>

-<p>If a binding appears twice in the routing rules, then the match will succeed only if they share the same value. This copies the Erlang pattern matching behavior.</p>

-<p>Finally, there are two special match values that can be used. The first is the atom <code>&apos;_&apos;</code> which will match any host or path.</p>

-<h2 id="_constraints">Constraints</h2>
-<p>After the matching has completed, the resulting bindings can be tested against a set of constraints. Constraints are only tested when the binding is defined. They run in the order you defined them. The match will succeed only if they all succeed. If the match fails, then Cowboy tries the next route in the list.</p>
-<p>The format used for constraints is the same as match functions in <code>cowboy_req</code>: they are provided as a list of fields which may have one or more constraints. While the router accepts the same format, it will skip fields with no constraints and will also ignore default values, if any.</p>
-<p>Read more about <a href="../constraints">constraints</a>.</p>
-<h2 id="_compilation">Compilation</h2>
-<p>The routes must be compiled before Cowboy can use them. The compilation step normalizes the routes to simplify the code and speed up the execution, but the routes are still looked up one by one in the end. Faster compilation strategies could be to compile the routes directly to Erlang code, but would require heavier dependencies.</p>
-<p>To compile routes, just call the appropriate function:</p>

-[[static_files]]
-== Static files
-
-Cowboy comes with a ready to use handler for serving static
-files. It is provided as a convenience for serving files
-during development.
-
-For systems in production, consider using one of the many
-Content Distribution Network (CDN) available on the market,
-as they are the best solution for serving files.
-
-The static handler can serve either one file or all files
-from a given directory. The etag generation and mime types
-can be configured.
-
-=== Serve one file
-
-You can use the static handler to serve one specific file
-from an application's private directory. This is particularly
-useful to serve an 'index.html' file when the client requests
-the `/` path, for example. The path configured is relative
-to the given application's private directory.
-
-The following rule will serve the file 'static/index.html'
-from the application `my_app`'s priv directory whenever the
-path `/` is accessed:
-
-[source,erlang]
-{"/", cowboy_static, {priv_file, my_app, "static/index.html"}}
-
-You can also specify the absolute path to a file, or the
-path to the file relative to the current directory:
-
-[source,erlang]
-{"/", cowboy_static, {file, "/var/www/index.html"}}
-
-=== Serve all files from a directory
-
-You can also use the static handler to serve all files that
-can be found in the configured directory. The handler will
-use the `path_info` information to resolve the file location,
-which means that your route must end with a `[...]` pattern
-for it to work. All files are served, including the ones that
-may be found in subfolders.
-
-You can specify the directory relative to an application's
-private directory.
-
-The following rule will serve any file found in the application
-`my_app`'s priv directory inside the `static/assets` folder
-whenever the requested path begins with `/assets/`:
-
-[source,erlang]
-{"/assets/[...]", cowboy_static, {priv_dir, my_app, "static/assets"}}
-
-You can also specify the absolute path to the directory or
-set it relative to the current directory:
-
-[source,erlang]
-{"/assets/[...]", cowboy_static, {dir, "/var/www/assets"}}
-
-=== Customize the mimetype detection
-
-By default, Cowboy will attempt to recognize the mimetype
-of your static files by looking at the extension.
-
-You can override the function that figures out the mimetype
-of the static files. It can be useful when Cowboy is missing
-a mimetype you need to handle, or when you want to reduce
-the list to make lookups faster. You can also give a
-hard-coded mimetype that will be used unconditionally.
-
-Cowboy comes with two functions built-in. The default
-function only handles common file types used when building
-Web applications. The other function is an extensive list
-of hundreds of mimetypes that should cover almost any need
-you may have. You can of course create your own function.
-
-To use the default function, you should not have to configure
-anything, as it is the default. If you insist, though, the
-following will do the job:
-
-[source,erlang]
-----
-{"/assets/[...]", cowboy_static, {priv_dir, my_app, "static/assets",
-    [{mimetypes, cow_mimetypes, web}]}}
-----
-
-As you can see, there is an optional field that may contain
-a list of less used options, like mimetypes or etag. All option
-types have this optional field.
-
-To use the function that will detect almost any mimetype,
-the following configuration will do:
-
-[source,erlang]
-----
-{"/assets/[...]", cowboy_static, {priv_dir, my_app, "static/assets",
-    [{mimetypes, cow_mimetypes, all}]}}
-----
-
-You probably noticed the pattern by now. The configuration
-expects a module and a function name, so you can use any
-of your own functions instead:
-
-[source,erlang]
-----
-{"/assets/[...]", cowboy_static, {priv_dir, my_app, "static/assets",
-    [{mimetypes, Module, Function}]}}
-----
-
-The function that performs the mimetype detection receives
-a single argument that is the path to the file on disk. It
-is recommended to return the mimetype in tuple form, although
-a binary string is also allowed (but will require extra
-processing). If the function can't figure out the mimetype,
-then it should return `{<<"application">>, <<"octet-stream">>, []}`.
-
-When the static handler fails to find the extension,
-it will send the file as `application/octet-stream`.
-A browser receiving such file will attempt to download it
-directly to disk.
-
-Finally, the mimetype can be hard-coded for all files.
-This is especially useful in combination with the `file`
-and `priv_file` options as it avoids needless computation:
-
-[source,erlang]
-----
-{"/", cowboy_static, {priv_file, my_app, "static/index.html",
-    [{mimetypes, {<<"text">>, <<"html">>, []}}]}}
-----
-
-=== Generate an etag
-
-By default, the static handler will generate an etag header
-value based on the size and modified time. This solution
-can not be applied to all systems though. It would perform
-rather poorly over a cluster of nodes, for example, as the
-file metadata will vary from server to server, giving a
-different etag on each server.
-
-You can however change the way the etag is calculated:
-
-[source,erlang]
-----
-{"/assets/[...]", cowboy_static, {priv_dir, my_app, "static/assets",
-    [{etag, Module, Function}]}}
-----
-
-This function will receive three arguments: the path to the
-file on disk, the size of the file and the last modification
-time. In a distributed setup, you would typically use the
-file path to retrieve an etag value that is identical across
-all your servers.
-
-You can also completely disable etag handling:
-
-[source,erlang]
-----
-{"/assets/[...]", cowboy_static, {priv_dir, my_app, "static/assets",
-    [{etag, false}]}}

-<p>The static handler can serve either one file or all files from a given directory. The etag generation and mime types can be configured.</p>
-<h2 id="_serve_one_file">Serve one file</h2>
-<p>You can use the static handler to serve one specific file from an application&apos;s private directory. This is particularly useful to serve an <em>index.html</em> file when the client requests the <code>/</code> path, for example. The path configured is relative to the given application&apos;s private directory.</p>
-<p>The following rule will serve the file <em>static/index.html</em> from the application <code>my_app</code>&apos;s priv directory whenever the path <code>/</code> is accessed:</p>

-<h2 id="_serve_all_files_from_a_directory">Serve all files from a directory</h2>
-<p>You can also use the static handler to serve all files that can be found in the configured directory. The handler will use the <code>path_info</code> information to resolve the file location, which means that your route must end with a <code>[...]</code> pattern for it to work. All files are served, including the ones that may be found in subfolders.</p>
-<p>You can specify the directory relative to an application&apos;s private directory.</p>
-<p>The following rule will serve any file found in the application <code>my_app</code>&apos;s priv directory inside the <code>static/assets</code> folder whenever the requested path begins with <code>/assets/</code>:</p>

-<h2 id="_customize_the_mimetype_detection">Customize the mimetype detection</h2>
-<p>By default, Cowboy will attempt to recognize the mimetype of your static files by looking at the extension.</p>
-<p>You can override the function that figures out the mimetype of the static files. It can be useful when Cowboy is missing a mimetype you need to handle, or when you want to reduce the list to make lookups faster. You can also give a hard-coded mimetype that will be used unconditionally.</p>
-<p>Cowboy comes with two functions built-in. The default function only handles common file types used when building Web applications. The other function is an extensive list of hundreds of mimetypes that should cover almost any need you may have. You can of course create your own function.</p>
-<p>To use the default function, you should not have to configure anything, as it is the default. If you insist, though, the following will do the job:</p>

-</div></div>
-<p>As you can see, there is an optional field that may contain a list of less used options, like mimetypes or etag. All option types have this optional field.</p>
-<p>To use the function that will detect almost any mimetype, the following configuration will do:</p>

-</div></div>
-<p>You probably noticed the pattern by now. The configuration expects a module and a function name, so you can use any of your own functions instead:</p>

-</div></div>
-<p>The function that performs the mimetype detection receives a single argument that is the path to the file on disk. It is recommended to return the mimetype in tuple form, although a binary string is also allowed (but will require extra processing). If the function can&apos;t figure out the mimetype, then it should return <code>{&lt;&lt;&quot;application&quot;&gt;&gt;, &lt;&lt;&quot;octet-stream&quot;&gt;&gt;, []}</code>.</p>
-<p>When the static handler fails to find the extension, it will send the file as <code>application/octet-stream</code>. A browser receiving such file will attempt to download it directly to disk.</p>
-<p>Finally, the mimetype can be hard-coded for all files. This is especially useful in combination with the <code>file</code> and <code>priv_file</code> options as it avoids needless computation:</p>

-</div></div>
-<h2 id="_generate_an_etag">Generate an etag</h2>
-<p>By default, the static handler will generate an etag header value based on the size and modified time. This solution can not be applied to all systems though. It would perform rather poorly over a cluster of nodes, for example, as the file metadata will vary from server to server, giving a different etag on each server.</p>
-<p>You can however change the way the etag is calculated:</p>
-<div class="listingblock"><div class="content"><!-- Generator: GNU source-highlight 3.1.8

-    [{<font color="#FF6600">etag</font>, <font color="#009900">Module</font>, <font color="#009900">Function</font>}]}}</tt></pre>
-</div></div>
-<p>This function will receive three arguments: the path to the file on disk, the size of the file and the last modification time. In a distributed setup, you would typically use the file path to retrieve an etag value that is identical across all your servers.</p>
-<p>You can also completely disable etag handling:</p>

-== Streams
-
-A stream is the set of messages that form an HTTP
-request/response pair.
-
-The term stream comes from HTTP/2. In Cowboy, it is
-also used when talking about HTTP/1.1 or HTTP/1.0.
-It should not be confused with streaming the request
-or response body.
-
-All versions of HTTP allow clients to initiate
-streams. HTTP/2 is the only one also allowing servers,
-through its server push feature. Both client and
-server-initiated streams go through the same process
-in Cowboy.
-
-=== Stream handlers
-
-Stream handlers must implement five different callbacks.
-Four of them are directly related; one is special.
-
-All callbacks receives the stream ID as first argument.
-
-Most of them can return a list of commands to be executed
-by Cowboy. When callbacks are chained, it is possible to
-intercept and modify these commands. This can be useful
-for modifying responses for example.
-
-The `init/3` callback is invoked when a new request
-comes in. It receives the Req object and the protocol options
-for this listener.
-
-The `data/4` callback is invoked when data from the request
-body is received. It receives both this data and a flag
-indicating whether more is to be expected.
-
-The `info/3` callback is invoked when an Erlang message is
-received for this stream. They will typically be messages
-sent by the request process.
-
-Finally the `terminate/3` callback is invoked with the
-terminate reason for the stream. The return value is ignored.
-Note that as with all terminate callbacks in Erlang, there
-is no strong guarantee that it will be called.
-
-The special callback `early_error/5` is called when an error
-occurs before the request headers were fully received and
-Cowboy is sending a response. It receives the partial Req
-object, the error reason, the protocol options and the response
-Cowboy will send. This response must be returned, possibly
-modified.
-
-=== Built-in handlers
-
-Cowboy comes with two handlers.
-
-`cowboy_stream_h` is the default stream handler.
-It is the core of much of the functionality of Cowboy.
-All chains of stream handlers should call it last.
-
-`cowboy_compress_h` will automatically compress
-responses when possible. It is not enabled by default.
-It is a good example for writing your own handlers
-that will modify responses.

-== Websocket handlers
-
-Websocket handlers provide an interface for upgrading HTTP/1.1
-connections to Websocket and sending or receiving frames on
-the Websocket connection.
-
-As Websocket connections are established through the HTTP/1.1
-upgrade mechanism, Websocket handlers need to be able to first
-receive the HTTP request for the upgrade, before switching to
-Websocket and taking over the connection. They can then receive
-or send Websocket frames, handle incoming Erlang messages or
-close the connection.
-
-=== Upgrade
-
-The `init/2` callback is called when the request is received.
-To establish a Websocket connection, you must switch to the
-`cowboy_websocket` module:
-
-[source,erlang]
-----
-init(Req, State) ->
-    {cowboy_websocket, Req, State}.
-----
-
-Cowboy will perform the Websocket handshake immediately. Note
-that the handshake will fail if the client did not request an
-upgrade to Websocket.
-
-The Req object becomes unavailable after this function returns.
-Any information required for proper execution of the Websocket
-handler must be saved in the state.
-
-=== Subprotocol
-
-The client may provide a list of Websocket subprotocols it
-supports in the sec-websocket-protocol header. The server *must*
-select one of them and send it back to the client or the
-handshake will fail.
-
-For example, a client could understand both STOMP and MQTT over
-Websocket, and provide the header:
-
-----
-sec-websocket-protocol: v12.stomp, mqtt
-----
-
-If the server only understands MQTT it can return:
-
-----
-sec-websocket-protocol: mqtt
-----
-
-This selection must be done in `init/2`. An example usage could
-be:
-
-[source,erlang]
-----
-init(Req0, State) ->
-    case cowboy_req:parse_header(<<"sec-websocket-protocol">>, Req0) of
-        undefined ->
-            {cowboy_websocket, Req0, State};
-        Subprotocols ->
-            case lists:keymember(<<"mqtt">>, 1, Subprotocols) of
-                true ->
-                    Req = cowboy_req:set_resp_header(<<"sec-websocket-protocol">>,
-                        <<"mqtt">>, Req0),
-                    {cowboy_websocket, Req, State};
-                false ->
-                    Req = cowboy_req:reply(400, Req0),
-                    {ok, Req, State}
-            end
-    end.
-----
-
-=== Post-upgrade initialization
-
-Cowboy has separate processes for handling the connection
-and requests. Because Websocket takes over the connection,
-the Websocket protocol handling occurs in a different
-process than the request handling.
-
-This is reflected in the different callbacks Websocket
-handlers have. The `init/2` callback is called from the
-temporary request process and the `websocket_` callbacks
-from the connection process.
-
-This means that some initialization cannot be done from
-`init/2`. Anything that would require the current pid,
-or be tied to the current pid, will not work as intended.
-The optional `websocket_init/1` can be used instead:
-
-[source,erlang]
-----
-websocket_init(State) ->
-    erlang:start_timer(1000, self(), <<"Hello!">>),
-    {ok, State}.
-----
-
-All Websocket callbacks share the same return values. This
-means that we can send frames to the client right after
-the upgrade:
-
-[source,erlang]
-----
-websocket_init(State) ->
-    {reply, {text, <<"Hello!">>}, State}.
-----
-
-=== Receiving frames
-
-Cowboy will call `websocket_handle/2` whenever a text, binary,
-ping or pong frame arrives from the client.
-
-The handler can handle or ignore the frames. It can also
-send frames back to the client or stop the connection.
-
-The following snippet echoes back any text frame received and
-ignores all others:
-
-[source,erlang]
-----
-websocket_handle(Frame = {text, _}, State) ->
-    {reply, Frame, State};
-websocket_handle(_Frame, State) ->
-    {ok, State}.
-----
-
-Note that ping and pong frames require no action from the
-handler as Cowboy will automatically reply to ping frames.
-They are provided for informative purposes only.
-
-=== Receiving Erlang messages
-
-Cowboy will call `websocket_info/2` whenever an Erlang message
-arrives.
-
-The handler can handle or ignore the messages. It can also
-send frames to the client or stop the connection.
-
-The following snippet forwards log messages to the client
-and ignores all others:
-
-[source,erlang]
-----
-websocket_info({log, Text}, State) ->
-    {reply, {text, Text}, State};
-websocket_info(_Info, State) ->
-    {ok, State}.
-----
-
-=== Sending frames
-
-// @todo This will be deprecated and eventually replaced with a
-// {Commands, State} interface that allows providing more
-// functionality easily.
-
-All `websocket_` callbacks share return values. They may
-send zero, one or many frames to the client.
-
-To send nothing, just return an ok tuple:
-
-[source,erlang]
-----
-websocket_info(_Info, State) ->
-    {ok, State}.
-----
-
-To send one frame, return a reply tuple with the frame to send:
-
-[source,erlang]
-----
-websocket_info(_Info, State) ->
-    {reply, {text, <<"Hello!">>}, State}.
-----
-
-You can send frames of any type: text, binary, ping, pong
-or close frames.
-
-To send many frames at once, return a reply tuple with the
-list of frames to send:
-
-[source,erlang]
-----
-websocket_info(_Info, State) ->
-    {reply, [
-        {text, "Hello"},
-        {text, <<"world!">>},
-        {binary, <<0:8000>>}
-    ], State}.
-----
-
-They are sent in the given order.
-
-=== Keeping the connection alive
-
-Cowboy will automatically respond to ping frames sent by
-the client. They are still forwarded to the handler for
-informative purposes, but no further action is required.
-
-Cowboy does not send ping frames itself. The handler can
-do it if required. A better solution in most cases is to
-let the client handle pings. Doing it from the handler
-would imply having an additional timer per connection and
-this can be a considerable cost for servers that need to
-handle large numbers of connections.
-
-Cowboy can be configured to close idle connections
-automatically. It is highly recommended to configure
-a timeout here, to avoid having processes linger longer
-than needed.
-
-The `init/2` callback can set the timeout to be used
-for the connection. For example, this would make Cowboy
-close connections idle for more than 30 seconds:
-
-[source,erlang]
-----
-init(Req, State) ->
-    {cowboy_websocket, Req, State, #{
-        idle_timeout => 30000}}.
-----
-
-This value cannot be changed once it is set. It defaults to
-`60000`.
-
-=== Saving memory
-
-The Websocket connection process can be set to hibernate
-after the callback returns.
-
-Simply add an `hibernate` field to the ok or reply tuples:
-
-[source,erlang]
-----
-websocket_init(State) ->
-    {ok, State, hibernate}.
-
-websocket_handle(_Frame, State) ->
-    {ok, State, hibernate}.
-
-websocket_info(_Info, State) ->
-    {reply, {text, <<"Hello!">>}, State, hibernate}.
-----
-
-It is highly recommended to write your handlers with
-hibernate enabled, as this allows to greatly reduce the
-memory usage. Do note however that an increase in the
-CPU usage or latency can be observed instead, in particular
-for the more busy connections.
-
-=== Closing the connection
-
-The connection can be closed at any time, either by telling
-Cowboy to stop it or by sending a close frame.
-
-To tell Cowboy to close the connection, use a stop tuple:
-
-[source,erlang]
-----
-websocket_info(_Info, State) ->
-    {stop, State}.
-----
-
-Sending a `close` frame will immediately initiate the closing
-of the Websocket connection. Note that when sending a list of
-frames that include a close frame, any frame found after the
-close frame will not be sent.

-<p>Cowboy will automatically respond to ping frames sent by the client. They are still forwarded to the handler for informative purposes, but no further action is required.</p>
-<p>Cowboy does not send ping frames itself. The handler can do it if required. A better solution in most cases is to let the client handle pings. Doing it from the handler would imply having an additional timer per connection and this can be a considerable cost for servers that need to handle large numbers of connections.</p>
-<p>Cowboy can be configured to close idle connections automatically. It is highly recommended to configure a timeout here, to avoid having processes linger longer than needed.</p>
-<p>The <code>init/2</code> callback can set the timeout to be used for the connection. For example, this would make Cowboy close connections idle for more than 30 seconds:</p>

-== The Websocket protocol
-
-This chapter explains what Websocket is and why it is
-a vital component of soft realtime Web applications.
-
-=== Description
-
-Websocket is an extension to HTTP that emulates plain TCP
-connections between the client, typically a Web browser,
-and the server. It uses the HTTP Upgrade mechanism to
-establish the connection.
-
-Websocket connections are fully asynchronous, unlike
-HTTP/1.1 (synchronous) and HTTP/2 (asynchronous, but the
-server can only initiate streams in response to requests).
-With Websocket, the client and the server can both send
-frames at any time without any restriction. It is closer
-to TCP than any of the HTTP protocols.
-
-Websocket is an IETF standard. Cowboy supports the standard
-and all drafts that were previously implemented by browsers,
-excluding the initial flawed draft sometimes known as
-"version 0".
-
-=== Websocket vs HTTP/2
-
-For a few years Websocket was the only way to have a
-bidirectional asynchronous connection with the server.
-This changed when HTTP/2 was introduced. While HTTP/2
-requires the client to first perform a request before
-the server can push data, this is only a minor restriction
-as the client can do so just as it connects.
-
-Websocket was designed as a kind-of-TCP channel to a
-server. It only defines the framing and connection
-management and lets the developer implement a protocol
-on top of it. For example you could implement IRC over
-Websocket and use a Javascript IRC client to speak to
-the server.
-
-HTTP/2 on the other hand is just an improvement over
-the HTTP/1.1 connection and request/response mechanism.
-It has the same semantics as HTTP/1.1.
-
-If all you need is to access an HTTP API, then HTTP/2
-should be your first choice. On the other hand, if what
-you need is a different protocol, then you can use
-Websocket to implement it.
-
-=== Implementation
-
-Cowboy implements Websocket as a protocol upgrade. Once the
-upgrade is performed from the `init/2` callback, Cowboy
-switches to Websocket. Please consult the next chapter for
-more information on initiating and handling Websocket
-connections.
-
-The implementation of Websocket in Cowboy is validated using
-the Autobahn test suite, which is an extensive suite of tests
-covering all aspects of the protocol. Cowboy passes the
-suite with 100% success, including all optional tests.
-
-Cowboy's Websocket implementation also includes the
-permessage-deflate and x-webkit-deflate-frame compression
-extensions.
-
-Cowboy will automatically use compression when the
-`compress` option is returned from the `init/2` function.

-<dl><dt>Name</dt>
-<dd><p>The listener name is used to refer to this listener in future calls, for example when stopping it or when updating the routes defined.</p>
-<p>It can be any Erlang term. An atom is generally good enough, for example <code>api</code>, <code>my_app_clear</code> or <code>my_app_tls</code>.</p>
-</dd>
-<dt>TransportOpts</dt>

-<p>Start listening for connections over a secure TLS channel.</p>
-<p>Both HTTP/1.1 and HTTP/2 are supported on this listener. The ALPN TLS extension must be used to initiate an HTTP/2 connection.</p>
-<h2 id="_arguments">Arguments</h2>
-<dl><dt>Name</dt>
-<dd><p>The listener name is used to refer to this listener in future calls, for example when stopping it or when updating the routes defined.</p>
-<p>It can be any Erlang term. An atom is generally good enough, for example <code>api</code>, <code>my_app_clear</code> or <code>my_app_tls</code>.</p>
-</dd>
-<dt>TransportOpts</dt>
-<dd><p>The transport options are where the TCP options, including the listener&apos;s port number, are defined. They also contain the TLS options, like the server&apos;s certificate. Transport options are provided as a list of keys and values, for example <code>[{port, 8443}, {certfile, &quot;path/to/cert.pem&quot;}]</code>.</p>
-<p>The available options are documented in the <a href="../ranch_ssl">ranch_ssl(3)</a> manual.</p>
-</dd>
-<dt>ProtocolOpts</dt>
-<dd><p>The protocol options are in a map containing all the options for the different protocols that may be involved when connecting to the listener, including HTTP/1.1 and HTTP/2.</p>
-<p>The HTTP/1.1 options are documented in the <a href="../cowboy_http">cowboy_http(3)</a> manual; and the HTTP/2 options in <a href="../cowboy_http2">cowboy_http2(3)</a>.</p>
-</dd>
-</dl>
-<h2 id="_return_value">Return value</h2>
-<p>An ok tuple is returned on success. It contains the pid of the top-level supervisor for the listener.</p>
-<p>An error tuple is returned on error. The error reason may be any Erlang term.</p>
-<p>A common error is <code>eaddrinuse</code>. It indicates that the port configured for Cowboy is already in use.</p>
-<h2 id="_changelog">Changelog</h2>
-<ul><li><strong>2.0</strong>: HTTP/2 support added.
-</li>
-<li><strong>2.0</strong>: Function introduced. Replaces <code>cowboy:start_https/4</code>.

-<p>cowboy_handler - Plain HTTP handlers</p>
-<h2 id="_description">Description</h2>
-<p>The <code>cowboy_handler</code> middleware executes the handler selected by the router or any other preceding middleware.</p>
-<p>This middleware takes the handler module and initial state from the <code>handler</code> and <code>handler_opts</code> environment values, respectively. On completion, it adds a <code>result</code> value to the middleware environment, containing the return value of the <code>terminate/3</code> callback (if defined) and <code>ok</code> otherwise.</p>
-<p>This module also defines a callback interface for handling HTTP requests.</p>
-<h2 id="_callbacks">Callbacks</h2>
-<p>Plain HTTP handlers implement the following interface:</p>

-<p>These two callbacks are common to all handlers.</p>
-<p>Plain HTTP handlers do all their work in the <code>init/2</code> callback. Returning <code>ok</code> terminates the handler. If no response is sent, Cowboy will send a <code>204 No Content</code>.</p>
-<p>The optional <code>terminate/3</code> callback will ultimately be called with the reason for the termination of the handler. Cowboy will terminate the process right after this. There is no need to perform any cleanup in this callback.</p>
-<p>The following terminate reasons are defined for plain HTTP handlers:</p>
-<dl><dt>normal</dt>
-<dd><p>The connection was closed normally.</p>
-</dd>
-<dt>{crash, Class, Reason}</dt>
-<dd><p>A crash occurred in the handler. <code>Class</code> and <code>Reason</code> can be used to obtain more information about the crash. The function <code>erlang:get_stacktrace/0</code> can also be called to obtain the stacktrace of the process when the crash occurred.</p>

-<h2 id="_exports">Exports</h2>

-<p>cowboy_loop - Loop handlers</p>
-<h2 id="_description">Description</h2>
-<p>The module <code>cowboy_loop</code> defines a callback interface for long running HTTP connections.</p>
-<p>You should switch to this behavior for long polling, server-sent events and similar long-running requests.</p>
-<p>There are generally two usage patterns:</p>
-<ul><li>Loop until receiving a specific message, then send a response and stop execution (for example long polling);
-</li>
-<li>Or initiate a response in <code>init/2</code> and stream the body in <code>info/3</code> as necessary (for example server-sent events).
-</li>
-</ul>
-<h2 id="_callbacks">Callbacks</h2>
-<p>Loop handlers implement the following interface:</p>

-<p>The <code>init/2</code> callback is common to all handlers. To switch to the loop behavior, it must return <code>cowboy_loop</code> as the first element of the tuple.</p>
-<p>The <code>info/3</code> callback will be called for every Erlang message received. It may choose to continue the receive loop or stop it.</p>
-<p>The optional <code>terminate/3</code> callback will ultimately be called with the reason for the termination of the handler. Cowboy will terminate the process right after this. There is no need to perform any cleanup in this callback.</p>
-<p>The following terminate reasons are defined for loop handlers:</p>
-<dl><dt>stop</dt>
-<dd><p>The handler requested to close the connection by returning a <code>stop</code> tuple.</p>
-</dd>
-<dt>{crash, Class, Reason}</dt>
-<dd><p>A crash occurred in the handler. <code>Class</code> and <code>Reason</code> can be used to obtain more information about the crash. The function <code>erlang:get_stacktrace/0</code> can also be called to obtain the stacktrace of the process when the crash occurred.</p>

-<p>Parse the cookies and match specific values against constraints.</p>
-<p>Cowboy will only return the cookie values specified in the fields list, and ignore all others. Fields can be either the name of the cookie requested; the name along with a list of constraints; or the name, a list of constraints and a default value in case the cookie is missing.</p>
-<p>This function will crash if the cookie is missing and no default value is provided. This function will also crash if a constraint fails.</p>
-<p>The name of the cookie must be provided as an atom. The key of the returned map will be that atom. The value may be converted through the use of constraints, making this function able to extract, validate and convert values all in one step.</p>

-<p>Parse the query string and match specific values against constraints.</p>
-<p>Cowboy will only return the query string values specified in the fields list, and ignore all others. Fields can be either the key requested; the key along with a list of constraints; or the key, a list of constraints and a default value in case the key is missing.</p>
-<p>This function will crash if the key is missing and no default value is provided. This function will also crash if a constraint fails.</p>
-<p>The key must be provided as an atom. The key of the returned map will be that atom. The value may be converted through the use of constraints, making this function able to extract, validate and convert values all in one step.</p>

-<p>The parsed query string is returned as a list of key/value pairs. The key is a binary string. The value is either a binary string, or the atom <code>true</code>. Both key and value are case sensitive.</p>
-<p>The atom <code>true</code> is returned when a key is present in the query string without a value. For example, in the following URIs the key <code>&lt;&lt;&quot;edit&quot;&gt;&gt;</code> will always have the value <code>true</code>:</p>
-<ul><li><code>/posts/42?edit</code>
-</li>
-<li><code>/posts/42?edit&amp;exclusive=1</code>
-</li>
-<li><code>/posts/42?exclusive=1&amp;edit</code>

-<h2 id="_changelog">Changelog</h2>
-<ul><li><strong>2.0</strong>: The parsed value is not longer cached in the Req object.

-<li><strong>2.0</strong>: Only the parsed query string is returned, it is no longer wrapped in a tuple.

-<p>Push a resource to the client.</p>
-<p>Cowboy handles push requests the same way as if they came from the client, including the creation of a request handling process, routing and middlewares and so on.</p>
-<p>This function does nothing when the HTTP/1.1 protocol is used. You may call it safely without first checking whether the connection uses HTTP/2.</p>
-<p>The header names must be given as lowercase binary strings. While header names are case insensitive, Cowboy requires them to be given as lowercase to function properly.</p>
-<p>Note that the headers must be the headers the client is expected to send if it were to perform the request. They are therefore request headers, and not response headers.</p>
-<p>By default, Cowboy will use the GET method, an empty query string, and take the scheme, host and port directly from the current request&apos;s URI. You can override them by passing options.</p>
-<p>It is not possible to push resources after sending a response. Any attempt will result in an error.</p>

-<p>Read the request body.</p>
-<p>This function reads a chunk of the request body. A <code>more</code> tuple is returned when more data remains to be read. Call the function repeatedly until an <code>ok</code> tuple is returned to read the entire body.</p>
-<p>An <code>ok</code> tuple with empty data is returned when the request has no body, or when calling this function again after the body has already been read. It is therefore safe to call this function directly. Note that the body can only be read once.</p>
-<p>This function reads the request body from the connection process. The connection process is responsible for reading from the socket. The exact behavior varies depending on the protocol.</p>
-<p>The options therefore are only related to the communication between the request process and the connection process.</p>
-<p>Cowboy will automatically handle protocol details including the expect header, chunked transfer-encoding and others.</p>
-<p>Once the body has been read fully, Cowboy sets the content-length header if it was not previously provided.</p>
-<h2 id="_arguments">Arguments</h2>
-<dl><dt>Req</dt>
-<dd><p>The Req object.</p>
-</dd>
-<dt>Opts</dt>
-<dd><p>A map of body reading options.</p>
-<p>The <code>length</code> option can be used to request smaller or bigger chunks of data to be sent. It is a best effort approach, Cowboy may send more data than configured on occasions. It defaults to 8MB.</p>
-<p>The <code>period</code> indicates how long the connection process will wait before it provides us with the data it received. It defaults to 15 seconds.</p>
-<p>The connection process sends data to the request process when either the <code>length</code> of data or the <code>period</code> of time is reached.</p>
-<p>The <code>timeout</code> option is a safeguard in case the connection process becomes unresponsive. The function will crash if no message was received in that interval. The timeout should be larger than the period. It defaults to the period + 1 second.</p>
-</dd>
-</dl>
-<h2 id="_return_value">Return value</h2>
-<p>A <code>more</code> tuple is returned when there are more data to be read.</p>
-<p>An <code>ok</code> tuple is returned when there are no more data to be read, either because this is the last chunk of data, the body has already been read, or there was no body to begin with.</p>
-<p>The data is always returned as a binary.</p>
-<p>The Req object returned in the tuple must be used for that point onward. It contains a more up to date representation of the request. For example it may have an added content-length header once the body has been read.</p>
-<h2 id="_changelog">Changelog</h2>

-<p>Read the next part of a multipart body.</p>
-<p>This function reads the request body and parses it as multipart. Each parts of a multipart representation have their own headers and body. This function parses and returns headers. Examples of multipart media types are <code>multipart/form-data</code> and <code>multipart/byteranges</code>.</p>
-<p>Cowboy will skip any data remaining until the beginning of the next part. This includes the preamble to the multipart message but also the body of a previous part if it hasn&apos;t been read. Both are skipped automatically when calling this function.</p>
-<p>Cowboy will read the body before parsing in chunks of size up to 64KB, with a period of 5 seconds. This is tailored for reading part headers and might not be the most efficient for skipping the previous part&apos;s body.</p>
-<p>The headers returned are MIME headers, <strong>NOT</strong> HTTP headers. They can be parsed using the functions from the <code>cow_multipart</code> module. In addition, the <code>cow_multipart:form_data/1</code> function can be used to quickly extract information from <code>multipart/form-data</code> representations.</p>
-<!-- @todo Proper link to cow_multipart:form_data.-->
-<p>Once a part has been read, it can not be read again.</p>
-<p>Once the body has been read, Cowboy sets the content-length header if it was not previously provided.</p>
-<!-- @todo Limit the maximum size of multipart headers.-->
-<h2 id="_arguments">Arguments</h2>
-<dl><dt>Req</dt>
-<dd><p>The Req object.</p>
-</dd>
-<dt>Opts</dt>
-<dd><p>A map of body reading options. Please refer to <a href="../cowboy_req.read_body">cowboy_req:read_body(3)</a> for details about each option.</p>
-<p>This function defaults the <code>length</code> to 64KB and the <code>period</code> to 5 seconds.</p>
-</dd>
-</dl>
-<h2 id="_return_value">Return value</h2>
-<p>An <code>ok</code> tuple is returned containing the next part&apos;s headers as a map.</p>
-<p>A <code>done</code> tuple is returned if there are no more parts to read.</p>
-<p>The Req object returned in the tuple must be used for that point onward. It contains a more up to date representation of the request. For example it may have an added content-length header once the body has been read.</p>
-<h2 id="_changelog">Changelog</h2>
-<ul><li><strong>2.0</strong>: Function introduced. Replaces <code>part/1,2</code>.

-<p>Read the body of the current part of the multipart message.</p>
-<p>This function reads the request body and parses it as multipart. Each parts of a multipart representation have their own headers and body. This function returns the body of the current part. Examples of multipart media types are <code>multipart/form-data</code> and <code>multipart/byteranges</code>.</p>
-<p>This function reads a chunk of the part&apos;s body. A <code>more</code> tuple is returned when more data remains to be read. Call the function repeatedly until an <code>ok</code> tuple is returned to read the entire body.</p>
-<p>Once a part has been read, it can not be read again.</p>
-<p>Once the body has been read, Cowboy sets the content-length header if it was not previously provided.</p>
-<!-- @todo Limit the maximum size of multipart headers.-->
-<h2 id="_arguments">Arguments</h2>
-<dl><dt>Req</dt>
-<dd><p>The Req object.</p>
-</dd>
-<dt>Opts</dt>
-<dd><p>A map of body reading options. Please refer to <a href="../cowboy_req.read_body">cowboy_req:read_body(3)</a> for details about each option.</p>
-<p>This function uses the same default options as the <a href="../cowboy_req.read_body">cowboy_req:read_body(3)</a> function.</p>
-</dd>
-</dl>
-<h2 id="_return_value">Return value</h2>
-<p>A <code>more</code> tuple is returned when there are more data to be read.</p>
-<p>An <code>ok</code> tuple is returned when there are no more data to be read.</p>
-<p>The data is always returned as a binary.</p>
-<p>The Req object returned in the tuple must be used for that point onward. It contains a more up to date representation of the request. For example it may have an added content-length header once the body has been read.</p>

-<p>Read and parse a urlencoded request body.</p>
-<p>This function reads the request body and parses it as <code>application/x-www-form-urlencoded</code>. It returns a list of key/values.</p>
-<p>The urlencoded media type is used by Web browsers when submitting HTML forms using the POST method.</p>
-<p>Cowboy needs to read the full body before parsing. By default it will read bodies of size up to 64KB. It is possible to provide options to read larger bodies if required.</p>
-<p>Cowboy will automatically handle protocol details including the expect header, chunked transfer-encoding and others.</p>
-<p>Once the body has been read, Cowboy sets the content-length header if it was not previously provided.</p>

-<p>Send the response.</p>
-<p>The header names must be given as lowercase binary strings. While header names are case insensitive, Cowboy requires them to be given as lowercase to function properly.</p>
-<p>Cowboy does not allow duplicate header names. Headers set by this function may overwrite those set by <code>set_resp_header/3</code> and <code>set_resp_headers/2</code>.</p>
-<p>Use <a href="../cowboy_req.set_resp_cookie">cowboy_req:set_resp_cookie(3)</a> instead of this function to set cookies.</p>
-<p>The <code>reply/2,3</code> functions will send the body set previously, if any. The <code>reply/4</code> function always sends the given body, overriding any previously set.</p>
-<p>You do not need to set the content-length header when sending a response body. Cowboy takes care of it automatically. You should however provide a content-type header.</p>
-<p>No further data can be transmitted after this function returns. This includes the push mechanism. Attempting to send two replies, or to push resources after a reply has been sent, will result in an error.</p>

-<p>Stream the response body.</p>
-<p>This function may be called as many times as needed after initiating a response using the <a href="../cowboy_req.stream_reply">cowboy_req:stream_reply(3)</a> function.</p>
-<p>The second argument indicates if this call is the final call. Use the <code>nofin</code> value until you know no more data will be sent. The final call should use <code>fin</code> (possibly with an empty data value).</p>
-<p>Note that not using <code>fin</code> for the final call is not an error; Cowboy will take care of it when the request handler terminates if needed. Depending on the resource it may however be more efficient to do it as early as possible.</p>
-<p>You do not need to handle HEAD requests specifically as Cowboy will ensure no data is sent when you call this function.</p>

-<p>The header names must be given as lowercase binary strings. While header names are case insensitive, Cowboy requires them to be given as lowercase to function properly.</p>
-<p>Cowboy does not allow duplicate header names. Headers set by this function may overwrite those set by <code>set_resp_header/3</code>.</p>
-<p>Use <a href="../cowboy_req.set_resp_cookie">cowboy_req:set_resp_cookie(3)</a> instead of this function to set cookies.</p>
-<p>If a response body was set before calling this function, it will not be sent.</p>

-<p>You may want to set the content-length header when using this function, if it is known in advance. This will allow clients using HTTP/2 and HTTP/1.0 to process the response more efficiently.</p>
-<p>The streaming method varies depending on the protocol being used. HTTP/2 will use the usual DATA frames. HTTP/1.1 will use chunked transfer-encoding. HTTP/1.0 will send the body unmodified and close the connection at the end if no content-length was set.</p>

-<p>cowboy_req - HTTP request and response</p>
-<h2 id="_description">Description</h2>
-<p>The module <code>cowboy_req</code> provides functions to access, manipulate and respond to requests.</p>
-<p>There are four types of functions in this module. They can be differentiated by their name and their return type:</p>
-<table rules="all" width="100%" frame="border"
-			cellspacing="0" cellpadding="4">
-<thead><tr><th>Type</th>
-<th>Name pattern</th>
-<th>Return type</th>
-</tr></thead><tbody><tr><td>access</td>
-<td>no verb, parse_*, match_*</td>
-<td><code>Value</code></td>
-</tr>
-<tr><td>question</td>
-<td>has_*</td>
-<td><code>boolean()</code></td>
-</tr>
-<tr><td>modification</td>
-<td>set_*</td>
-<td><code>Req</code></td>
-</tr>
-<tr><td>action</td>
-<td>any other verb</td>
-<td><code>ok | {Result, Value, Req}</code></td>
-</tr>
-</tbody></table>
-<p>Any <code>Req</code> returned must be used in place of the one passed as argument. Functions that perform an action in particular write state in the Req object to make sure you are using the function correctly. For example, it&apos;s only possible to send one response, and to read the body once.</p>

-<p>The <code>init/2</code> callback is common to all handlers. To switch to the REST handler behavior, it must return <code>cowboy_rest</code> as the first element of the tuple.</p>
-<p>The <code>Callback/2</code> above represents all the REST-specific callbacks. They are described in the following section of this manual. REST-specific callbacks differ by their name, semantics, result and default values. The default value is the one used when the callback has not been implemented. They otherwise all follow the same interface.</p>
-<p>The <code>stop</code> tuple can be returned to stop REST processing. If no response was sent before then, Cowboy will send a <em>204 No Content</em>. The <code>stop</code> tuple can be returned from any callback, excluding <code>expires</code>, <code>generate_etag</code>, <code>last_modified</code> and <code>variances</code>.</p>
-<p>A <code>switch_handler</code> tuple can be returned from these same callbacks to stop REST processing and switch to a different handler type. This is very useful to, for example, to stream the response body.</p>
-<p>The optional <code>terminate/3</code> callback will ultimately be called with the reason for the termination of the handler. Cowboy will terminate the process right after this. There is no need to perform any cleanup in this callback.</p>
-<p>The following terminate reasons are defined for loop handlers:</p>
-<dl><dt>normal</dt>
-<dd><p>The handler terminated normally.</p>
-</dd>
-<dt>{crash, Class, Reason}</dt>
-<dd><p>A crash occurred in the handler. <code>Class</code> and <code>Reason</code> can be used to obtain more information about the crash. The function <code>erlang:get_stacktrace/0</code> can also be called to obtain the stacktrace of the process when the crash occurred.</p>

When creating a new resource with POST at a different location, return <code>{true, URI}</code> with <code>URI</code> the new location.</p>
-<p>For PATCH requests, the body is a series of instructions on how to update the resource. Patch files or JSON Patch are examples of such media types.</p>
-<p>A response body may be sent. The appropriate media type, charset and language for the response can be retrieved from the Req object using the <code>media_type</code>, <code>charset</code> and <code>language</code> keys, respectively. The body can be set using <a href="../cowboy_req.set_resp_body">cowboy_req:set_resp_body(3)</a>.</p>

-<p>cowboy_router - Router middleware</p>
-<h2 id="_description">Description</h2>
-<p>The <code>cowboy_router</code> middleware maps the requested host and path to the handler to be used for processing the request.</p>
-<p>The router takes the <code>dispatch</code> rules as input from the middleware environment. Dispatch rules are generated by calling the <a href="../cowboy_router.compile">cowboy_router:compile(3)</a> function.</p>
-<p>When a route matches, the router sets the <code>handler</code> and <code>handler_opts</code> middleware environment values containing the handler module and initial state, respectively.</p>
-<p>The router will stop execution when no route matches. It will send a 400 response if no host was found, and a 404 response otherwise.</p>

-<p>cowboy_handler - Stream handlers</p>
-<h2 id="_description">Description</h2>
-<p>The module <code>cowboy_stream</code> defines a callback interface and a protocol for handling HTTP streams.</p>
-<p>An HTTP request and its associated response is called a stream. A connection may have many streams. In HTTP/1.1 they are executed sequentially, while in HTTP/2 they are executed concurrently.</p>
-<p>Cowboy calls the stream handler for nearly all events related to a stream. Exceptions vary depending on the protocol.</p>
-<p>Extra care must be taken when implementing stream handlers to ensure compatibility. While some modification of the events and commands is allowed, it is generally not a good idea to completely omit them.</p>
-<h2 id="_callbacks">Callbacks</h2>
-<p>Stream handlers must implement the following interface:</p>

-<p>HTTP/1.1 will initialize a stream only when the request-line and all headers have been received. When errors occur before that point Cowboy will call the callback <code>early_error/5</code> with a partial request, the error reason and the response Cowboy intends to send. All other events go throuh the stream handler using the normal callbacks.</p>
-<p>HTTP/2 will initialize the stream when the <code>HEADERS</code> block has been fully received and decoded. Any protocol error occuring before that will not result in a response being sent and will therefore not go through the stream handler. In addition Cowboy may terminate streams without sending an HTTP response back.</p>
-<p>The stream is initialized by calling <code>init/3</code>. All streams that are initialized will eventually be terminated by calling <code>terminate/3</code>.</p>
-<p>When Cowboy receives data for the stream it will call <code>data/4</code>. The data given is the request body after any transfer decoding has been applied.</p>
-<p>When Cowboy receives a message addressed to a stream, or when Cowboy needs to inform the stream handler that an internal event has occurred, it will call <code>info/3</code>.</p>
-<h2 id="commands">Commands</h2>
-<p>Stream handlers can return a list of commands to be executed from the <code>init/3</code>, <code>data/4</code> and <code>info/3</code> callbacks. In addition, the <code>early_error/5</code> callback must return a response command.</p>
-<!-- @todo We need a &apos;log&apos; command that would call error_logger.-->
-<!-- It&apos;s better than doing in the handlers directly because-->
-<!-- then we can have other stream handlers manipulate those logs.-->
-<!-- @todo We need a command to send a message so that other-->
-<!-- stream handlers can manipulate these messages if necessary.-->
-<p>The following commands are defined:</p>
-<h3 id="response_command">response</h3>

-<p>The <code>init/2</code> callback is common to all handlers. To upgrade the connection to Websocket, it must return <code>cowboy_websocket</code> as the first element of the tuple.</p>
-<p>Any operation requiring the HTTP request must be done in the <code>init/2</code> function, as the Req object will not be available after it returns. Websocket sub-protocol selection should therefore be done in this function.</p>
-<p>The optional <code>websocket_init/1</code> callback will be called once the connection has been upgraded to Websocket. It can be used to perform any required initialization of the handler.</p>
-<p>Note that the <code>init/2</code> function does not run in the same process as the Websocket callbacks. Any Websocket-specific initialization must be done in <code>websocket_init/1</code>.</p>
-<p>The <code>websocket_handle/2</code> callback will be called for every frame received. The <code>websocket_info/2</code> callback will be called for every Erlang message received.</p>
-<p>All three Websocket callbacks may send one or more frames back to the client (by returning a <code>reply</code> tuple) or terminate the connection (by sending a <code>close</code> frame or returning a <code>stop</code> tuple).</p>
-<p>The optional <code>terminate/3</code> callback will ultimately be called with the reason for the termination of the connection. This callback is common to all handlers. Note that Websocket will not provide the full Req object by default, to save memory.</p>
-<p>Cowboy will terminate the process right after closing the Websocket connection. This means that there is no need to perform any cleanup in the <code>terminate/3</code> callback.</p>
-<p>The following terminate reasons are defined for Websocket connections:</p>
-<dl><dt>normal</dt>
-<dd><p>The connection was closed normally before establishing a Websocket connection. This typically happens if an <code>ok</code> tuple is returned from the <code>init/2</code> callback.</p>
-</dd>
-<dt>remote</dt>
-<dd><p>The remote endpoint closed the connection without giving any further details.</p>
-</dd>
-<dt>{remote, Code, Payload}</dt>
-<dd><p>The remote endpoint closed the connection with the given <code>Code</code> and <code>Payload</code> as the reason.</p>
-</dd>
-<dt>stop</dt>
-<dd><p>The handler requested to close the connection, either by returning a <code>stop</code> tuple or by sending a <code>close</code> frame.</p>
-</dd>
-<dt>timeout</dt>
-<dd><p>The connection has been closed due to inactivity. The timeout value can be configured from <code>init/2</code>.</p>
-</dd>
-<dt>{crash, Class, Reason}</dt>
-<dd><p>A crash occurred in the handler. <code>Class</code> and <code>Reason</code> can be used to obtain more information about the crash. The function <code>erlang:get_stacktrace/0</code> can also be called to obtain the stacktrace of the process when the crash occurred.</p>
-</dd>
-<dt>{error, badencoding}</dt>
-<dd><p>A text frame was sent by the client with invalid encoding. All text frames must be valid UTF-8.</p>
-</dd>
-<dt>{error, badframe}</dt>
-<dd><p>A protocol error has been detected.</p>
-</dd>
-<dt>{error, closed}</dt>
-<dd><p>The socket has been closed brutally without a close frame being received first.</p>
-</dd>
-<dt>{error, Reason}</dt>
-<dd><p>A socket error ocurred.</p>

-== Building
-
-Erlang.mk can do a lot of things, but it is, first and
-foremost, a build tool. In this chapter we will cover
-the basics of building a project with Erlang.mk.
-
-For most of this chapter, we will assume that you are
-using a project xref:getting_started[generated by Erlang.mk].
-
-=== How to build
-
-To build a project, all you have to do is type `make`:
-
-[source,bash]
-$ make
-
-It will work regardless of your project: OTP applications,
-library applications, NIFs, port drivers or even releases.
-Erlang.mk also automatically downloads and compiles the
-dependencies for your project.
-
-All this is possible thanks to a combination of configuration
-and conventions. Most of the conventions come from Erlang/OTP
-itself so any seasoned Erlang developers should feel right at
-home.
-
-Erlang.mk supports multi-threaded building. Parallel execution
-is supported for all targets. To execute Erlang.mk in parallel
-the `-j` option must be used:
-
-[source,bash]
-$ make -j8
-
-The `MAKEFLAGS` variable can be used to enable parallel
-building permanently on your system. It can be set in
-your `.zshrc`, `.bashrc` or equivalent file.
-
-[source,bash]
-MAKEFLAGS="-j8"
-
-=== What to build
-
-Erlang.mk gives you control over three steps of the build
-process, allowing you to do a partial build if needed.
-
-A build has three phases: first any dependency is fetched
-and built, then the project itself is built and finally a
-release may be generated when applicable. A release is only
-generated for projects specifically configured to do so.
-
-Erlang.mk handles those three phases automatically when you
-type `make`. But sometimes you just want to repeat one or
-two of them.
-
-The commands detailed in this section are most useful after
-you have a successful build as they allow you to quickly
-redo a step instead of going through everything. This is
-especially useful for large projects or projects that end
-up generating releases.
-
-==== Application
-
-You can build your application and dependencies without
-generating a release by running the following command:
-
-[source,bash]
-$ make app
-
-To build your application without touching dependencies
-at all, you can use the `SKIP_DEPS` variable:
-
-[source,bash]
-$ make app SKIP_DEPS=1
-
-This command is very useful if you have a lot of dependencies
-and develop on a machine with slow file access, like the
-Raspberry Pi and many other embedded devices.
-
-Note that this command may fail if a required dependency
-is missing.
-
-==== Dependencies
-
-You can build all dependencies, and nothing else, by
-running the following command:
-
-[source,bash]
-$ make deps
-
-This will fetch and compile all dependencies and their
-dependencies, recursively.
-
-xref:deps[Packages and dependencies] are covered
-in the next chapter.
-
-==== Release
-
-It is not possible to build the release without at least
-building the application itself, unless of course if there's
-no application to begin with.
-
-To generate the release, `make` will generally suffice with
-a normal Erlang.mk. A separate target is however available,
-and will take care of building the release, after building
-the application and all dependencies:
-
-[source,bash]
-$ make rel
-
-Consult the xref:relx[Releases] chapter for more
-information about what releases are and how they are generated.
-
-=== Application resource file
-
-When building your application, Erlang.mk will generate the
-http://www.erlang.org/doc/man/app.html[application resource file].
-This file is mandatory for all Erlang applications and is
-found in 'ebin/$(PROJECT).app'.
-
-`PROJECT` is a variable defined in your Makefile and taken
-from the name of the directory when Erlang.mk bootstraps
-your project.
-
-Erlang.mk can build the 'ebin/$(PROJECT).app' in two different
-ways: from the configuration found in the Makefile, or from
-the 'src/$(PROJECT).app.src' file.
-
-==== Application configuration
-
-Erlang.mk automatically fills the `PROJECT` variable when
-bootstrapping a new project, but everything else is up to
-you. None of the values are required to build your project,
-although it is recommended to fill everything relevant to
-your situation.
-
-`PROJECT`::
-	The name of the OTP application or library.
-`PROJECT_DESCRIPTION`::
-	Short description of the project.
-`PROJECT_VERSION`::
-	Current version of the project.
-`PROJECT_MOD`::
-        The application callback module.
-`PROJECT_REGISTERED`::
-	List of the names of all registered processes.
-`PROJECT_ENV`::
-	Configuration parameters used by the application.
-`PROJECT_APP_EXTRA_KEYS`::
-	Other keys you want to add to the application `.app` file.
-	The variable content is written as-is to the `.app` file,
-	so be sure to format valid Erlang terms. For example:
-	`PROJECT_APP_EXTRA_KEYS = {maxT, 10000}, {start_phases, [...]}`.
-`LOCAL_DEPS`::
-	List of Erlang/OTP applications this project depends on,
-	excluding `erts`, `kernel` and `stdlib`, or list of
-	dependencies local to this repository (in `APPS_DIR`).
-`DEPS`::
-	List of applications this project depends on that need
-	to be fetched by Erlang.mk.
-
-There's no need for quotes or anything. The relevant part of
-the Cowboy Makefile follows, if you need an example:
-
-[source,make]
-----
-PROJECT = cowboy
-PROJECT_DESCRIPTION = Small, fast, modular HTTP server.
-PROJECT_VERSION = 2.0.0-pre.2
-PROJECT_REGISTERED = cowboy_clock
-
-LOCAL_DEPS = crypto
-DEPS = cowlib ranch
-----
-
-Any space before and after the value is dropped.
-
-xref:deps[Dependencies] are covered in details in
-the next chapter.
-
-==== Application environment
-
-The `PROJECT_ENV` variable is used to set the application
-environment:
-
-[source,make]
-----
-define PROJECT_ENV
-[
-  {chips, [currysauce,{mushypeas,false}]},
-  {pizza, [{size,large},{toppings,[anchovies]}]}
-]
-endef
-----
-
-If you have a large set of environment variables, you may find it
-easier to use a separate file. Do this by including the following
-in your Makefile:
-
-[source,make]
-----
-PROJECT_ENV_FILE = src/env.src
-PROJECT_ENV = $(subst \n,$(newline),$(shell cat $(PROJECT_ENV_FILE) | sed -e 's/$$/\\n/;'))
-ebin/$(PROJECT).app:: $(PROJECT_ENV_FILE)
-----
-
-The file has the same contents as the `PROJECT_ENV` variable:
-
-[source,erlang]
-----
-[
-  {chips, [currysauce,{mushypeas,false}]},
-  {pizza, [{size,large},{toppings,[anchovies]}]}
-]
-----
-
-==== Legacy method
-
-The 'src/$(PROJECT).app.src' file is a legacy method of
-building Erlang applications. It was introduced by the original
-`rebar` build tool, of which Erlang.mk owes a great deal as it
-is its main inspiration.
-
-The '.app.src' file serves as a template to generate the '.app'
-file. Erlang.mk will take it, fill in the `modules` value
-dynamically, and save the result in 'ebin/$(PROJECT).app'.
-
-When using this method, Erlang.mk cannot fill the `applications`
-key from dependencies automatically, which means you need to
-add them to Erlang.mk and to the '.app.src' at the same time,
-duplicating the work.
-
-If you really can't live without the legacy method, for one
-reason or another, worry not; Erlang.mk will support it. And
-if you need to create a new project that uses this method, you
-just have to say so when bootstrapping:
-
-[source,bash]
-$ make -f erlang.mk bootstrap-lib LEGACY=1
-
-=== Automatic application resource file values
-
-When building the application resource file, Erlang.mk may
-automatically add an `id` key with information about the
-Git commit (if using Git), or an empty string otherwise.
-It will only do this under specific conditions:
-
-* The application was built as a dependency of another, or
-* The legacy method was used, and the '.app.src' file contained `{id, "git"}`
-
-This value is most useful when you need to help your users,
-as it allows you to know which version they run exactly by
-asking them to look in the file, or by running a simple
-command on their production server:
-
-[source,erlang]
-----
-1> application:get_all_key(cowboy).
-{ok,[{description,"Small, fast, modular HTTP server."},
-     {id,"2.0.0-pre.2-25-g0ffde50-dirty"},
-----
-
-=== File formats
-
-Erlang.mk supports a variety of different source file formats.
-The following formats are supported natively:
-
-[cols="<,3*^",options="header"]
-|===
-| Extension | Location | Description        | Output
-| .erl      | src/     | Erlang source      | ebin/*.beam
-| .core     | src/     | Core Erlang source | ebin/*.beam
-| .xrl      | src/     | Leex source        | src/*.erl
-| .yrl      | src/     | Yecc source        | src/*.erl
-| .asn1     | asn1/    | ASN.1 files        | include/*.hrl include/*.asn1db src/*.erl
-| .mib      | mibs/    | SNMP MIB files     | include/*.hrl priv/mibs/*.bin
-|===
-
-Files are always searched recursively.
-
-The build is ordered, so that files that generate Erlang source
-files are run before, and the resulting Erlang source files are
-then built normally.
-
-In addition, Erlang.mk keeps track of header files (`.hrl`)
-as described at the end of this chapter. It can also compile
-C code, as described in the xref:ports[NIFs and port drivers]
-chapter.
-
-Erlang.mk also comes with plugins for the following formats:
-
-[cols="<,3*^",options="header"]
-|===
-| Extension | Location   | Description      | Output
-| .dtl      | templates/ | Django templates | ebin/*.beam
-| .proto    | src/       | Protocol buffers | ebin/*.beam
-|===
-
-=== Compilation options
-
-Erlang.mk provides a few variables that you can use to customize
-the build process and the resulting files.
-
-==== ERLC_OPTS
-
-`ERLC_OPTS` can be used to pass some options to `erlc`, the Erlang
-compiler. Erlang.mk does not restrict any option. Please refer to
-the http://www.erlang.org/doc/man/erlc.html[erlc Manual] for the
-full list.
-
-By default, Erlang.mk will set the following options:
-
-[source,make]
-ERLC_OPTS = -Werror +debug_info +warn_export_vars +warn_shadow_vars +warn_obsolete_guard
-
-In other words: warnings as errors, debug info (recommended) and
-enable warnings for exported variables, shadow variables and
-obsolete guard functions.
-
-You can redefine this variable in your Makefile to change it
-completely, either before or after including Erlang.mk:
-
-[source,make]
-ERLC_OPTS = +debug_info
-
-You can also filter out some options from the defaults Erlang.mk
-sets, by defining ERLC_OPTS after including Erlang.mk using the
-`:=` operator.
-
-[source,make]
-----
-include erlang.mk
-
-ERLC_OPTS := $(filter-out -Werror,$(ERLC_OPTS))
-----
-
-==== ERLC_ASN1_OPTS
-
-`ERLC_ASN1_OPTS` can be used to pass compiler options when compiling
-ASN.1 files.  Please refer to the
-http://erlang.org/doc/man/asn1ct.html[asn1ct manual] for the full list.
-
-By default, Erlang.mk will leave this empty.
-
-You can redefine this variable in your Makefile.
-Please see the `ERLC_OPTS` section for instructions.
-
-==== ERLC_EXCLUDE
-
-`ERLC_EXCLUDE` can be used to exclude some modules from the
-compilation. It's there for handling special cases, you should
-not normally need it.
-
-To exclude a module, simply list it in the variable, either
-before or after including Erlang.mk:
-
-[source,make]
-ERLC_EXCLUDE = cowboy_http2
-
-=== Cold and hot builds
-
-The first time you run `make`, Erlang.mk will build everything.
-
-The second time you run `make`, and all subsequent times, Erlang.mk
-will only rebuild what changed. Erlang.mk has been optimized for
-this use case, as it is the most common during development.
-
-Erlang.mk figures out what changed by using the dependency tracking
-feature of Make. Make automatically rebuilds a target if one of its
-dependency has changed (for example if a header file has changed,
-all the source files that include it will be rebuilt), and Erlang.mk
-leverages this feature to cut down on rebuild times.
-
-Note that this applies only to building; some other features of
-Erlang.mk will run every time they are called regardless of files
-changed.
-
-=== Dependency tracking
-
-NOTE: This section is about the dependency tracking between files
-inside your project, not application dependencies.
-
-Erlang.mk keeps track of the dependencies between the different
-files in your project. This information is kept in the '$(PROJECT).d'
-file in your directory. It is generated if missing, and will be
-generated again after every file change, by default.
-
-Dependency tracking is what allows Erlang.mk to know when to
-rebuild Erlang files when header files, behaviors or parse
-transforms have changed. Erlang.mk also automatically keeps
-track of which files should be compiled first, for example
-when you have behaviors used by other modules in your project.
-
-If your project is stable, you may want to disable generating
-the dependency tracking file every time you compile. You can
-do this by adding the following line to your 'Makefile':
-
-[source,make]
-NO_MAKEDEP ?= 1
-
-As you can see, the snippet above uses `?=` instead of a
-simple equal sign. This is to allow you to temporarily override
-this value when you do make substantial changes to your project
-(including a new header file, new module with dependencies, etc.)
-and want to rebuild the dependency tracking file. You'll be
-able to use the following command:
-
-[source,bash]
-$ NO_MAKEDEP= make
-
-Otherwise, `make clean app` will of course force the
-recompilation of your project.
-
-Erlang.mk can also keep track of the source files generated
-by other means, for example if you generate code from a data
-file in your repository.
-
-=== Generating Erlang source
-
-Erlang.mk provides hooks at different stages of the build process.
-When your goal is to generate Erlang source files, you can
-add your own rules before or after the dependency tracking
-file is generated. To do this, you would add your hook before
-or after including the 'erlang.mk' file.
-
-The easiest way is after:
-
-[source,make]
-----
-PROJECT = example
-
-include erlang.mk
-
-$(PROJECT).d:: src/generated_mod.erl
-
-src/generated_mod.erl:: gen-mod.sh
-	$(gen_verbose) ./gen-mod.sh $@
-----
-
-In this case we use `$(gen_verbose)` to hide the details of
-the build by default. Erlang.mk will simply say what file
-is it currently generating.
-
-When using an external script to generate the Erlang source
-file, it is recommended to depend on that script, so that
-the source file gets generated again when the script gets
-modified.
-
-If for whatever reason you prefer to hook before including
-Erlang.mk, don't forget to set the `.DEFAULT_GOAL` variable,
-otherwise nothing will get built:
-
-[source,make]
-----
-PROJECT = example
-
-.DEFAULT_GOAL = all
-
-$(PROJECT).d:: src/generated_mod.erl
-
-include erlang.mk
-
-src/generated_mod.erl:: gen-mod.sh
-	$(gen_verbose) ./gen-mod.sh $@
-----
-
-=== Cleaning
-
-Building typically involves creating a lot of new files. Some
-are reused in rebuilds, some are simply replaced. All can be
-removed safely.
-
-Erlang.mk provides two commands to remove them: `clean` and
-`distclean`. `clean` removes all the intermediate files that
-were created as a result of building, including the BEAM files,
-the dependency tracking file and the generated documentation.
-`distclean` removes these and more, including the downloaded
-dependencies, Dialyzer's PLT file and the generated release,
-putting your directory back to the state it was before you
-started working on it.
-
-To clean:
-
-[source,bash]
-$ make clean
-
-Or distclean:
-
-[source,bash]
-$ make distclean
-
-That is the question.
-
-Note that Erlang.mk will automatically clean some files as
-part of other targets, but it will never run `distclean` if
-you don't explicitly use it.

-<p>It will work regardless of your project: OTP applications, library applications, NIFs, port drivers or even releases. Erlang.mk also automatically downloads and compiles the dependencies for your project.</p>
-<p>All this is possible thanks to a combination of configuration and conventions. Most of the conventions come from Erlang/OTP itself so any seasoned Erlang developers should feel right at home.</p>
-<p>Erlang.mk supports multi-threaded building. Parallel execution is supported for all targets. To execute Erlang.mk in parallel the <code>-j</code> option must be used:</p>

-<h4 id="_legacy_method">Legacy method</h4>
-<p>The <em>src/$(PROJECT).app.src</em> file is a legacy method of building Erlang applications. It was introduced by the original <code>rebar</code> build tool, of which Erlang.mk owes a great deal as it is its main inspiration.</p>
-<p>The <em>.app.src</em> file serves as a template to generate the <em>.app</em> file. Erlang.mk will take it, fill in the <code>modules</code> value dynamically, and save the result in <em>ebin/$(PROJECT).app</em>.</p>
-<p>When using this method, Erlang.mk cannot fill the <code>applications</code> key from dependencies automatically, which means you need to add them to Erlang.mk and to the <em>.app.src</em> at the same time, duplicating the work.</p>
-<p>If you really can&apos;t live without the legacy method, for one reason or another, worry not; Erlang.mk will support it. And if you need to create a new project that uses this method, you just have to say so when bootstrapping:</p>

-</li>
-<li>The legacy method was used, and the <em>.app.src</em> file contained <code>{id, &quot;git&quot;}</code>
-</li>
-</ul>
-<p>This value is most useful when you need to help your users, as it allows you to know which version they run exactly by asking them to look in the file, or by running a simple command on their production server:</p>

-<h2 id="_cold_and_hot_builds">Cold and hot builds</h2>
-<p>The first time you run <code>make</code>, Erlang.mk will build everything.</p>
-<p>The second time you run <code>make</code>, and all subsequent times, Erlang.mk will only rebuild what changed. Erlang.mk has been optimized for this use case, as it is the most common during development.</p>
-<p>Erlang.mk figures out what changed by using the dependency tracking feature of Make. Make automatically rebuilds a target if one of its dependency has changed (for example if a header file has changed, all the source files that include it will be rebuilt), and Erlang.mk leverages this feature to cut down on rebuild times.</p>
-<p>Note that this applies only to building; some other features of Erlang.mk will run every time they are called regardless of files changed.</p>
-<h2 id="_dependency_tracking">Dependency tracking</h2>
-<p>NOTE: This section is about the dependency tracking between files inside your project, not application dependencies.</p>
-<p>Erlang.mk keeps track of the dependencies between the different files in your project. This information is kept in the <em>$(PROJECT).d</em> file in your directory. It is generated if missing, and will be generated again after every file change, by default.</p>
-<p>Dependency tracking is what allows Erlang.mk to know when to rebuild Erlang files when header files, behaviors or parse transforms have changed. Erlang.mk also automatically keeps track of which files should be compiled first, for example when you have behaviors used by other modules in your project.</p>
-<p>If your project is stable, you may want to disable generating the dependency tracking file every time you compile. You can do this by adding the following line to your <em>Makefile</em>:</p>

-</div></div>
-<p>As you can see, the snippet above uses <code>?=</code> instead of a simple equal sign. This is to allow you to temporarily override this value when you do make substantial changes to your project (including a new header file, new module with dependencies, etc.) and want to rebuild the dependency tracking file. You&apos;ll be able to use the following command:</p>

-</div></div>
-<p>Otherwise, <code>make clean app</code> will of course force the recompilation of your project.</p>
-<p>Erlang.mk can also keep track of the source files generated by other means, for example if you generate code from a data file in your repository.</p>
-<h2 id="_generating_erlang_source">Generating Erlang source</h2>
-<p>Erlang.mk provides hooks at different stages of the build process. When your goal is to generate Erlang source files, you can add your own rules before or after the dependency tracking file is generated. To do this, you would add your hook before or after including the <em>erlang.mk</em> file.</p>
-<p>The easiest way is after:</p>
-<div class="listingblock"><div class="content"><!-- Generator: GNU source-highlight 3.1.8

-http://www.lorenzobettini.it
-http://www.gnu.org/software/src-highlite -->

-</div></div>
-<p>In this case we use <code>$(gen_verbose)</code> to hide the details of the build by default. Erlang.mk will simply say what file is it currently generating.</p>
-<p>When using an external script to generate the Erlang source file, it is recommended to depend on that script, so that the source file gets generated again when the script gets modified.</p>
-<p>If for whatever reason you prefer to hook before including Erlang.mk, don&apos;t forget to set the <code>.DEFAULT_GOAL</code> variable, otherwise nothing will get built:</p>

-<h2 id="_cleaning">Cleaning</h2>
-<p>Building typically involves creating a lot of new files. Some are reused in rebuilds, some are simply replaced. All can be removed safely.</p>
-<p>Erlang.mk provides two commands to remove them: <code>clean</code> and <code>distclean</code>. <code>clean</code> removes all the intermediate files that were created as a result of building, including the BEAM files, the dependency tracking file and the generated documentation. <code>distclean</code> removes these and more, including the downloaded dependencies, Dialyzer&apos;s PLT file and the generated release, putting your directory back to the state it was before you started working on it.</p>
-<p>To clean:</p>

-</div></div>
-<p>That is the question.</p>
-<p>Note that Erlang.mk will automatically clean some files as part of other targets, but it will never run <code>distclean</code> if you don&apos;t explicitly use it.</p>

-== AsciiDoc documentation
-
-Erlang.mk provides rules for generating documentation from
-AsciiDoc files. It can automatically build a user guide PDF,
-chunked HTML documentation and Unix manual pages.
-
-=== Requirements
-
-It is necessary to have http://asciidoc.org/[AsciiDoc], 
-http://xmlsoft.org/XSLT/xsltproc2.html[xsltproc] and
-http://dblatex.sourceforge.net/[dblatex] installed on your
-system for Erlang.mk to generate documentation from AsciiDoc sources.
-
-=== Writing AsciiDoc documentation
-
-http://asciidoc.org/[AsciiDoc] is a text document format for
-writing notes, documentation, articles, books, ebooks, slideshows,
-web pages, man pages and blogs. AsciiDoc files can be translated
-to many formats including HTML, PDF, EPUB, man page.
-
-The http://asciidoc.org/userguide.html[AsciiDoc user guide]
-describes the AsciiDoc syntax.
-
-The https://github.com/ninenines/erlang.mk/tree/master/doc/src/guide[Erlang.mk user guide]
-is written in AsciiDoc and can be used as an example. The entry
-file is https://github.com/ninenines/erlang.mk/blob/master/doc/src/guide/book.asciidoc[book.asciidoc].
-
-Erlang.mk expects you to put your documentation in a specific
-location. This is 'doc/src/guide/' for the user guide, and
-'doc/src/manual/' for the function reference. In the case of
-the user guide, the entry point is always 'doc/src/guide/book.asciidoc'.
-
-For manual pages, it is good practice to use section 3 for
-modules, and section 7 for the application itself.
-
-=== Configuration
-
-All of the AsciiDoc related configuration can be done directly
-inside the files themselves.
-
-=== Usage
-
-To build all documentation:
-
-[source,bash]
-$ make docs
-
-To build only the AsciiDoc documentation:
-
-[source,bash]
-$ make asciidoc
-
-To build only the user guide:
-
-[source,bash]
-$ make asciidoc-guide
-
-To build only the manual:
-
-[source,bash]
-$ make asciidoc-manual
-
-To install man pages on Unix:
-
-[source,bash]
-$ make install-docs
-
-Erlang.mk allows customizing the installation path and sections
-of the man pages to be installed. The `MAN_INSTALL_PATH` variable
-defines where man pages will be installed. It defaults to
-'/usr/local/share/man'. The `MAN_SECTIONS` variable defines
-which manual sections are to be installed. It defaults to `3 7`.
-
-To install man pages to a custom location:
-
-[source,bash]
-$ make install-docs MAN_INSTALL_PATH=/opt/share/man
-
-Note that you may need to run the install commands using
-`sudo` or equivalent if the location is not writeable by
-your user.

-<p>Erlang.mk provides rules for generating documentation from AsciiDoc files. It can automatically build a user guide PDF, chunked HTML documentation and Unix manual pages.</p>
-<h2 id="_requirements">Requirements</h2>
-<p>It is necessary to have <a href="http://asciidoc.org/">AsciiDoc</a>, <a href="http://xmlsoft.org/XSLT/xsltproc2.html">xsltproc</a> and <a href="http://dblatex.sourceforge.net/">dblatex</a> installed on your system for Erlang.mk to generate documentation from AsciiDoc sources.</p>
-<h2 id="_writing_asciidoc_documentation">Writing AsciiDoc documentation</h2>
-<p><a href="http://asciidoc.org/">AsciiDoc</a> is a text document format for writing notes, documentation, articles, books, ebooks, slideshows, web pages, man pages and blogs. AsciiDoc files can be translated to many formats including HTML, PDF, EPUB, man page.</p>
-<p>The <a href="http://asciidoc.org/userguide.html">AsciiDoc user guide</a> describes the AsciiDoc syntax.</p>
-<p>The <a href="https://github.com/ninenines/erlang.mk/tree/master/doc/src/guide">Erlang.mk user guide</a> is written in AsciiDoc and can be used as an example. The entry file is <a href="https://github.com/ninenines/erlang.mk/blob/master/doc/src/guide/book.asciidoc">book.asciidoc</a>.</p>
-<p>Erlang.mk expects you to put your documentation in a specific location. This is <em>doc/src/guide/</em> for the user guide, and <em>doc/src/manual/</em> for the function reference. In the case of the user guide, the entry point is always <em>doc/src/guide/book.asciidoc</em>.</p>
-<p>For manual pages, it is good practice to use section 3 for modules, and section 7 for the application itself.</p>

-[[ci]]
-== Continuous integration
-
-Erlang.mk comes with some support for continuous integration,
-aimed at open source projects that need to support more than
-one specific Erlang/OTP release. (If you target one specific
-release, check the xref:otp_version_pinning[OTP version pinning]
-section of the xref:kerl[OTP version management] chapter.)
-
-=== Configuring Erlang/OTP versions to test
-
-To use the CI plugin you must first configure which versions
-of Erlang/OTP will be used. Erlang.mk provides three separate
-configuration variables depending on whether you need a normal
-OTP release, a HiPE-enabled release or an ErLLVM-enabled release.
-
-At the time of writing, this is how you would test against all
-the most recent patch releases of Erlang/OTP 19 and above:
-
-[source,make]
-CI_OTP = OTP-19.0.7 OTP-19.1.6 OTP-19.2.3 OTP-19.3.6.2 OTP-20.0.4
-
-If you want to test against HiPE and ErLLVM but only with the
-latest version of Erlang/OTP, the following could work:
-
-[source,make]
-CI_HIPE = $(lastword $(CI_OTP))
-CI_ERLLVM = $(CI_HIPE)
-
-Consult the xref:kerl[OTP version management] chapter for more
-information about Erlang/OTP versions and customization of the
-Erlang/OTP builds.
-
-=== Running tests across all configured versions
-
-The recommended way to run the `ci` target is with the option
-`-k`. It will ensure that tests are run for all configured
-Erlang/OTP versions, even if there are errors:
-
-[source,bash]
-$ make ci -k
-
-=== Extending the CI targets
-
-The `ci` target can be extended. For example to run Dialyzer
-at the end of CI:
-
-[source,make]
-----
-ci:: dialyze
-----
-
-Additional setup can be done by extending the `ci-setup`
-target. This target is ran before testing each individual
-Erlang/OTP version.
-
-For example, to ensure dependencies are re-fetched/built
-before testing individual Erlang/OTP releases:
-
-[source,make]
-----
-ci-setup:: distclean
-----
-
-Similarly, the `ci-extra` target can be extended to run
-extra commands after an Erlang/OTP version has been tested.

-[[ct]]
-== Common Test
-
-Common Test is Erlang's functional testing framework.
-Erlang.mk automates the discovery and running of Common
-Test suites.
-
-=== Writing tests
-
-The http://www.erlang.org/doc/apps/common_test/write_test_chapter.html[Common Test user guide]
-is the best place to learn how to write tests. Erlang.mk
-requires that file names for test suites end with '_SUITE.erl'
-and that the files be located in the '$(TEST_DIR)' directory.
-This defaults to 'test/'.
-
-=== Configuration
-
-The `CT_OPTS` variable allows you to set extra Common Test
-options. Options are documented in the
-http://www.erlang.org/doc/apps/common_test/run_test_chapter.html[Common Test user guide].
-You can use it to set Common Test hooks, for example:
-
-[source,make]
-CT_OPTS = -ct_hooks cowboy_ct_hook
-
-The `CT_SUITES` variable can be used to override what
-Common Test suites Erlang.mk will be aware of. It does
-not normally need to be set as Erlang.mk will find the
-test suites automatically.
-
-The name of the suite is the part before `_SUITE.erl`.
-If the file is named 'http_SUITE.erl', the test suite
-is `http`:
-
-[source,make]
-CT_SUITES = http ws
-
-The `CT_LOGS_DIR` variable can be used to set where HTML
-log files are to be written. This defaults to 'logs/'.
-
-[source,make]
-CT_LOGS_DIR = ct_output_log_dir
-
-=== Usage
-
-To run all tests (including Common Test):
-
-[source,bash]
-$ make tests
-
-To run all tests and static checks (including Common Test):
-
-[source,bash]
-$ make check
-
-You can also run Common Test separately:
-
-[source,bash]
-$ make ct
-
-Erlang.mk will create targets for all test suites it finds.
-If you have a file named 'test/http_SUITE.erl', then the
-target `ct-http` will run that specific test suite:
-
-[source,bash]
-$ make ct-http
-
-Erlang.mk provides a convenient way to run a specific
-group or a specific test case within a specific group,
-using the variable `t`. Note that this only applies to
-suite-specific targets, like the `ct-http` example above.
-
-To run all tests from the `http_compress` group in the
-`http_SUITE` test suite, write:
-
-[source,bash]
-$ make ct-http t=http_compress
-
-Similarly, to run a specific test case in that group:
-
-[source,bash]
-$ make ct-http t=http_compress:headers_dupe
-
-To do the same against a multi-application repository,
-you can use the `-C` option:
-
-[source,bash]
-$ make -C apps/my_app ct-http t=my_group:my_case
-
-Note that this also applies to dependencies. When using Cowboy
-as a dependency, you can run the following directly:
-
-[source,bash]
-$ make -C deps/cowboy ct-http t=http_compress
-
-The variable `c` can be used to run a specific test when
-the test suite does not group test cases:
-
-[source,bash]
-$ make ct-http c=headers_dupe
-
-Finally, xref:coverage[code coverage] is available,
-but covered in its own chapter.

-[[compat]]
-== Compatibility with other build tools
-
-Erlang.mk tries its best to be compatible with the other Erlang
-build tools. It can use dependencies written with other build
-tools in mind, and can also make your projects usable by those
-build tools as well. Erlang.mk is like the cool kid that gets
-along with everybody.
-
-In this chapter I will use the term _Rebar project_ to refer
-to a project built using Rebar 2, Rebar 3 or Mad. These three
-build tools are very similar and share the same configuration
-file.
-
-=== Rebar projects as Erlang.mk dependencies
-
-Erlang.mk comes with a feature called _Autoload_ which will
-use Rebar 2 to patch any Rebar project and make it compatible
-with Erlang.mk. This feature essentially patches Rebar out
-and adds a Makefile to the project that Erlang.mk can then
-use for building:
-
-_Autoload_ is documented in more details in the
-xref:deps[Packages and dependencies] chapter.
-
-=== Erlang.mk projects as Rebar dependencies
-
-Erlang.mk projects can be made compatible with the Rebar family
-of build tools pretty easily, as Erlang.mk will generate
-all the files they require for building.
-
-The Rebar family requires two files: a 'rebar.config' file
-containing compilation options and the list of dependencies,
-and the application resource file, found either at
-'ebin/$(PROJECT).app' or at 'src/$(PROJECT).app.src'.
-
-==== Rebar configuration
-
-Erlang.mk comes with a target that generates a 'rebar.config'
-file when invoked:
-
-[source,bash]
-$ make rebar.config
-
-Careful! This will build the file even if it already existed
-before.
-
-To build this file, Erlang.mk uses information it finds in
-the `DEPS` and `ERLC_OPTS` variables, among others. This
-means that the Rebar family builds your project much the
-same way as Erlang.mk.
-
-// @todo Sanity check chapter.
-Careful though! Different build tools have different fetching
-strategies. If some applications provide differing dependencies,
-they might be fetched differently by other build tools. Check
-the upcoming Sanity check chapter to find out how to detect such
-issues.
-
-You can automatically generate this file when you build
-your application, by making it a dependency of the `app`
-target:
-
-[source,make]
-----
-app:: rebar.config
-----
-
-Don't forget to commit the file when it changes!
-
-If you run into other issues, it's probably because you use a
-feature specific to Erlang.mk, like the `cp` fetch method.
-It could also be that we forgot to handle something! Sorry.
-We are of course interested to hear about any compatibility
-problems you may have, just open a ticket!
-
-==== Application resource file
-
-Erlang.mk has two ways to generate an application resource
-file: from the information found in the Makefile, or from
-the information found in the 'src/$(PROJECT).app.src' file.
-Needless to say, if you have this file in your repository,
-then you don't need to worry about compatibility with other
-build tools.
-
-If you don't, however, it's not much harder. Every time
-Erlang.mk will compile your application, it will produce
-a new 'ebin/$(PROJECT).app' file. Simply commit this file
-when it changes. It will only change when you modify the
-configuration, add or remove modules.

-<h1 class="lined-header"><span>Compatibility with other build tools</span></h1>
-
-<p>Erlang.mk tries its best to be compatible with the other Erlang build tools. It can use dependencies written with other build tools in mind, and can also make your projects usable by those build tools as well. Erlang.mk is like the cool kid that gets along with everybody.</p>
-<p>In this chapter I will use the term <em>Rebar project</em> to refer to a project built using Rebar 2, Rebar 3 or Mad. These three build tools are very similar and share the same configuration file.</p>
-<h2 id="_rebar_projects_as_erlang_mk_dependencies">Rebar projects as Erlang.mk dependencies</h2>
-<p>Erlang.mk comes with a feature called <em>Autoload</em> which will use Rebar 2 to patch any Rebar project and make it compatible with Erlang.mk. This feature essentially patches Rebar out and adds a Makefile to the project that Erlang.mk can then use for building:</p>
-<p><em>Autoload</em> is documented in more details in the <a href="../deps">Packages and dependencies</a> chapter.</p>
-<h2 id="_erlang_mk_projects_as_rebar_dependencies">Erlang.mk projects as Rebar dependencies</h2>
-<p>Erlang.mk projects can be made compatible with the Rebar family of build tools pretty easily, as Erlang.mk will generate all the files they require for building.</p>
-<p>The Rebar family requires two files: a <em>rebar.config</em> file containing compilation options and the list of dependencies, and the application resource file, found either at <em>ebin/$(PROJECT).app</em> or at <em>src/$(PROJECT).app.src</em>.</p>
-<h4 id="_rebar_configuration">Rebar configuration</h4>
-<p>Erlang.mk comes with a target that generates a <em>rebar.config</em> file when invoked:</p>
-<div class="listingblock"><div class="content"><!-- Generator: GNU source-highlight 3.1.8
-by Lorenzo Bettini
-http://www.lorenzobettini.it
-http://www.gnu.org/software/src-highlite -->
-<pre><tt>$ make rebar<font color="#990000">.</font>config</tt></pre>
-</div></div>
-<p>Careful! This will build the file even if it already existed before.</p>
-<p>To build this file, Erlang.mk uses information it finds in the <code>DEPS</code> and <code>ERLC_OPTS</code> variables, among others. This means that the Rebar family builds your project much the same way as Erlang.mk.</p>
-<!-- @todo Sanity check chapter.-->
-<p>Careful though! Different build tools have different fetching strategies. If some applications provide differing dependencies, they might be fetched differently by other build tools. Check the upcoming Sanity check chapter to find out how to detect such issues.</p>
-<p>You can automatically generate this file when you build your application, by making it a dependency of the <code>app</code> target:</p>
-<div class="listingblock"><div class="content"><!-- Generator: GNU source-highlight 3.1.8
-by Lorenzo Bettini
-http://www.lorenzobettini.it
-http://www.gnu.org/software/src-highlite -->
-<pre><tt><font color="#990000">app::</font> rebar.config</tt></pre>
-</div></div>
-<p>Don&apos;t forget to commit the file when it changes!</p>
-<p>If you run into other issues, it&apos;s probably because you use a feature specific to Erlang.mk, like the <code>cp</code> fetch method. It could also be that we forgot to handle something! Sorry. We are of course interested to hear about any compatibility problems you may have, just open a ticket!</p>
-<h4 id="_application_resource_file">Application resource file</h4>
-<p>Erlang.mk has two ways to generate an application resource file: from the information found in the Makefile, or from the information found in the <em>src/$(PROJECT).app.src</em> file. Needless to say, if you have this file in your repository, then you don&apos;t need to worry about compatibility with other build tools.</p>
-<p>If you don&apos;t, however, it&apos;s not much harder. Every time Erlang.mk will compile your application, it will produce a new <em>ebin/$(PROJECT).app</em> file. Simply commit this file when it changes. It will only change when you modify the configuration, add or remove modules.</p>

-[[contributing]]
-== Contributing
-
-You are welcome and encouraged to contribute.
-
-This is how.
-
-=== Priorities
-
-From the most important to the least important:
-
-* Bugs
-* Package issues/additions
-* Refactoring
-* Features
-
-=== Bugs
-
-If you have found a bug, you should open a ticket. Include
-everything relevant including the command you used, output,
-a link to the code that triggers the issue, why you think
-this is a bug, etc.
-
-If you think you have found a bug but you are not sure, you
-should open a ticket as previously explained.
-
-If you have found a bug and you need it to be solved RIGHT
-NOW, open a ticket as previously explained.
-
-Once you have opened a ticket, be patient, try to answer
-questions in a timely manner and confirm that the bug was
-indeed fixed when it is.
-
-If you can't be patient, either try to solve the bug and
-contribute the fix back or become a paying customer.
-
-=== Code
-
-The code is located in the 'core/\*.mk' and 'plugins/\*.mk' files.
-The tests are located in the 'test/Makefile' and 'test/*.mk' files.
-
-If you have a fix or a hack for a bug, you should open a
-pull request. Any fix should include a test case that fails
-before the fix and is working after.
-
-If you have a test case that reproduces a bug, but no fix for
-it, you should open a pull request.
-
-Changes need to be tested with at least the `make check`
-command. A specific test case can be tested using `make check c=CASE`
-with `CASE` the name of the target to run. Output can be
-modulated using the `V` variable, which is an integer
-from 0 to 4. A typical use would be `make check c=dialyzer V=3`.
-The value 4 is particular and shows expanded commands right
-before they are executed.
-
-To run tests in parallel, use the `-j` option. It is generally
-a good idea to also use the `-k` option to run all tests even
-if one fails. For example: `make check -j 32 -k`.
-
-Some changes should be tested against all packages. Continue
-reading for more details on testing them.
-
-=== Packages
-
-You can search existing packages using the `make search q=STRING`
-command. This can be done both from an Erlang.mk project or
-directly from the Erlang.mk repository.
-
-Packages can be added to the index using the `pkg_add.sh` script.
-
-[source,bash]
-----
-$ git clone https://github.com/$YOURUSERNAME/erlang.mk
-$ cd erlang.mk
-$ ./pkg_add.sh cowboy git https://github.com/ninenines/cowboy 1.0.0
-  http://ninenines.eu "Small, fast and modular HTTP server."
-$ git push origin master
-----
-
-Before sending a pull request, you should test your package.
-You can use the following command: `make check p=PACKAGE`,
-where `PACKAGE` is the name of the package, for example
-`cowboy`.
-
-To test all packages, the `make packages` command can be used.
-This can take a long time. Some packages will fail with certain
-versions of Erlang, or if a prerequisite is missing from your system.
-You can of course speed things up using the `-j` and `-k` flags.
-
-After all packages have been tested, you can run the command
-`make summary` to know what changed since the previous run.
-
-=== Documentation
-
-The documentation is always right.
-
-If you think you have found a mistake in the documentation,
-this is a bug. You can either open a ticket or send a pull
-request.
-
-To make sure that the documentation changes work, install
-the listed xref:asciidoc[Requirements] on your system and
-run `make docs`.
-
-=== Feature requests
-
-If you have an awesome idea or need something that Erlang.mk
-doesn't provide yet, open a ticket. Provide as much detail as
-possible.
-
-If you have code, great! Open a pull request as previously
-explained.
-
-If not, you can still improve your feature request by writing
-the related documentation.

-[[coverage]]
-== Code coverage
-
-Erlang.mk provides support for code coverage via the tool
-`cover` that comes with Erlang/OTP. Code coverage lets you
-see what parts of your code are covered by the tests.
-
-=== Enabling cover when running tests
-
-To run tests with code coverage enabled, simply define
-`COVER=1` either on the command line or in your Makefile:
-
-[source,bash]
-$ make tests COVER=1
-
-When running the targets `tests` or `check` the code
-coverage report will be built automatically. This is
-not the case for test framework specific targets,
-however. In those cases you can generate the reports
-manually:
-
-[source,bash]
-$ make eunit proper COVER=1
-$ make cover-report
-
-Note that Common Test has some support for `cover`
-built-in and that it will generate code coverage
-reports in the Common Test logs regardless. The
-report that Erlang.mk generates is however common
-to all test frameworks and might be more useful.
-
-=== Adding applications to the cover report
-
-By default Erlang.mk will include all the applications
-in the code coverage report, except external dependencies.
-
-To include some dependencies in the report, you can
-define the `COVER_DEPS` variable:
-
-[source,make]
-COVER_DEPS = cowlib
-
-When using multi application repositories you can exclude
-some applications by defining the `COVER_APPS` variable:
-
-[source,make]
-COVER_APPS = presence backend
-
-=== Configuring paths
-
-By default Erlang.mk will store 'coverdata' files and
-code coverage reports under the 'cover/' directory. The
-variables `COVER_DATA_DIR` and `COVER_REPORT_DIR` can be
-set to use a different location.
-
-=== Merging coverdata files
-
-The target `all.coverdata` will take all existing
-'coverdata' files and merge them into one:
-
-[source,bash]
-$ make all.coverdata

-[[cross_compiling]]
-== Cross compiling
-
-Erlang.mk supports cross-compiling. While the compiled
-Erlang code is portable as-is, the C code is not and
-releases need to use the correct runtime system for the
-target environment.
-
-There are therefore two steps that might require some
-intervention: compiling and building the release. If
-you do not have any C code you can just compile as you
-would normally, however.
-
-=== Compiling
-
-To cross-compile the C code you need a cross compiler. If you
-were to target Windows from an Arch Linux machine you would
-install the https://aur.archlinux.org/packages/mingw-w64-gcc/[mingw-w64-gcc]
-package. You would then need to define the `CC` environment
-variable to point to this compiler instead of the default:
-
-[source,bash]
-CC=/usr/bin/x86_64-w64-mingw32-gcc
-
-Additionally, on Windows the shared libraries use a different
-extension than on Linux, so it needs to be specified as well:
-
-[source,bash]
-C_SRC_OUTPUT_SHARED_EXTENSION=.dll
-
-These values can be added to the Makefile or given from the
-command line, for example:
-
-[source,bash]
-----
-$ CC=/usr/bin/x86_64-w64-mingw32-gcc C_SRC_OUTPUT_SHARED_EXTENSION=.dll make
- DEPEND my_nif.d
- ERLC   my_nif.erl
- APP    my_nif
- C      my_nif.c
- LD     my_nif.dll
-$ file priv/my_nif.dll                                              
-priv/my_nif.dll: PE32+ executable (DLL) (console) x86-64, for MS Windows
-----
-
-You could also add this configuration to your Makefile hidden
-behind a flag:
-
-[source,make]
-----
-ifdef WINDOWS_BUILD
-CC = /usr/bin/x86_64-w64-mingw32-gcc
-C_SRC_OUTPUT_SHARED_EXTENSION = .dll
-endif
-----
-
-And then just compile like this:
-
-[source,bash]
-$ make WINDOWS_BUILD=1
-
-=== Building the release
-
-For the release there are two options. You can either include
-the correct runtime system directly in the release; or you
-can not include the runtime system in the release and instead
-let it use the one installed in the target environment.
-
-To include the target runtime system, add the `include_erts`
-tuple to your 'relx.config' file:
-
-[source,erlang]
-{include_erts, "/path/to/alternate/erlang"}.
-
-If you were to target Windows for example, you could copy
-the Erlang installation from the 'Program Files' directory
-and then configure 'relx.config' like this:
-
-[source,erlang]
-{include_erts, "/path/to/erl10.1"}.
-
-You need to make sure that the runtime system version you
-will use is capable of running the compiled Erlang code
-you used to build your project, otherwise it will fail
-to run.
-
-If you choose to not include the runtime system at all,
-configure 'relx.config' as follow:
-
-[source,erlang]
-{include_erts, false}.
-
-In that case the runtime system needs to be available
-in the `$PATH` of the target environment.

-== Packages and dependencies
-
-Erlang.mk can fetch and compile the dependencies that your
-project requires. Erlang.mk improves upon the concepts
-introduced by Rebar, so they should be familiar to many
-seasoned Erlang developers.
-
-Erlang.mk is not a package manager, nor is it trying to be,
-but it does include an index of Erlang packages to make
-discovering useful projects easier.
-
-This chapter will explain how to use packages, add
-dependencies to your project or bundle them directly
-in a single repository.
-
-=== Searching packages
-
-Erlang.mk gives you access to nearly 500 packages, with more
-being added regularly.
-
-To find a package, search for it:
-
-[source,bash]
-$ make search q=pool
-
-This will return all packages matching this word, like worker
-pool and acceptor pool projects.
-
-You can also list everything and use regular command line
-tools to find what you need, for example:
-
-[source,bash]
-$ make search | less
-
-// @todo Simplify adding packages, add a new chapter explaining
-// everything, then link to this new chapter from here.
-
-=== Adding dependencies to your project
-
-Once you find the package you need, adding it as a dependency
-to your project is a one-liner:
-
-[source,make]
-DEPS = cowboy
-
-And that's it! The next time you run `make`, Erlang.mk will
-fetch and compile Cowboy. Erlang.mk will also ensure Cowboy
-is available whenever you use the shell, run tests and any
-other operations.
-
-Erlang.mk will fill in the application resource file with
-all applications found in `DEPS`. But not all dependencies
-are Erlang applications, and not all dependencies need to
-be a runtime dependency. That's where the `BUILD_DEPS`
-variable comes in: it works just like `DEPS`, except the
-dependencies listed there will not be added as runtime
-dependencies.
-
-For example, you could add a parse transform project like
-this to make it available only at build time:
-
-[source,make]
-BUILD_DEPS = erlando
-
-Or you could depend on a C project directly, if you are
-building a NIF:
-
-[source,make]
-BUILD_DEPS = leveldb
-dep_leveldb = git https://github.com/basho/leveldb 2.1.3
-
-This dependency will be built before your application, so
-you could easily copy the resulting shared file into your
-'priv/' directory as part of the build process. More information
-about that in the xref:ports[NIFs and port drivers]
-chapter.
-
-Another variable, `LOCAL_DEPS`, allows specifying runtime
-dependencies which are part of Erlang/OTP itself, but also
-dependencies that are included in the repository. Since they
-are already on your system, there is no need to fetch them.
-Do note that there is no way to choose the version, the
-application used will be the one already on your system.
-
-You could depend on the Crypto application, for example:
-
-[source,make]
-LOCAL_DEPS = crypto
-
-Erlang.mk comes with additional types of dependencies.
-It has `TEST_DEPS` for dependencies used only for testing:
-
-[source,make]
-TEST_DEPS = ct_helper
-dep_ct_helper = git https://github.com/ninenines/ct_helper master
-
-`DOC_DEPS` for dependencies used only when building documentation:
-
-[source,make]
-DOC_DEPS = edown
-
-`REL_DEPS` for dependencies required to build the release,
-or to include extra applications in the release:
-
-[source,make]
-REL_DEPS = recon
-
-And `SHELL_DEPS` for dependencies to make available when running
-the `make shell` command:
-
-[source,make]
-SHELL_DEPS = tddreloader
-
-All these will be documented in more details in their respective
-chapters.
-
-Note that these additional types of dependencies will only
-be fetched after normal dependencies by default. You can
-force a dependency to be downloaded first by extending the
-target `deps::` before including 'erlang.mk', for example:
-
-[source,make]
-deps:: $(CURDIR)/deps/triq
-
-==== Modifying the dependency source or version
-
-By default, Erlang.mk will look into its package index to
-find the project you are looking for, if you only provide
-its name. This is this case:
-
-[source,make]
-DEPS = cowboy
-
-If you need a different version, you need to define another
-variable. There are two ways to do this, each being useful
-for different reasons.
-
-If you simply want to change the commit number, all you
-need to do is to define the `dep_$(DEP_NAME)_commit`
-variable. In the case of Cowboy, this would look like this:
-
-[source,make]
-DEPS = cowboy
-dep_cowboy_commit = 2.0.0-pre.2
-
-Erlang.mk will use the package index to get all information
-about Cowboy, except the commit number which will be overriden.
-
-If you need to set the fetch method or repository information
-too, for example because you want to use your own fork, or
-simply because the project is missing from the index, you
-can define the `dep_$(DEP_NAME)` variable with everything:
-
-[source,make]
-DEPS = cowboy
-dep_cowboy = git https://github.com/essen/cowboy 2.0.0-pre.2
-
-This will fetch Cowboy from your fork at the given commit.
-
-==== Fetch methods
-
-Erlang.mk comes with a number of different fetch methods.
-You can fetch from Git, Mercurial, SVN, to name a few.
-There are fetch methods that will work everywhere, and
-fetch methods that will only work in a given environment.
-
-The following table lists all existing methods:
-
-[cols="<,2*^",options="header"]
-|===
-| Name           | Format          | Description
-| git            | git repo commit | Clone the Git repository and checkout the given version
-| git-subfolder  | git repo commit subfolder | Clone the Git repository, checkout the given version and use one of its subfolders as a dependency
-| git-submodule  | git-submodule   | Initialize and update the Git submodule
-| hg             | hg repo commit  | Clone the Mercurial repository and update to the given version
-| svn            | svn repo        | Checkout the given SVN repository
-| cp             | cp path/to/repo | Recursively copy a local directory
-| ln             | ln path/to/repo | Symbolically link a local directory
-| hex            | hex version     | Download the given project version from hex.pm
-| fail           | N/A             | Always fail, reserved for internal use
-| legacy         | N/A             | Legacy Erlang.mk fetcher, reserved for internal use
-|===
-
-The `git` and `hg` methods both have a repository and commit.
-You can use any valid commit, tag or branch in that repository
-for the commit value.
-
-For example, to fetch Cowboy with tag 2.0.0-pre.2 from Git:
-
-[source,make]
-dep_cowboy = git https://github.com/ninenines/cowboy 2.0.0-pre.2
-
-Or to fetch Ehsa tag 4.0.3 from Mercurial:
-
-[source,make]
-dep_ehsa = hg https://bitbucket.org/a12n/ehsa 4.0.3
-
-Git also comes with a concept of submodules. Erlang.mk can
-automatically initializes and updates submodules for dependencies,
-as long as they were added beforehand using `git submodule add`:
-
-[source,make]
-dep_cowboy = git-submodule
-
-The `svn` method only has a repository value, but that's
-simply because the SVN repository URL can also contain
-the path and commit.
-
-This would fetch an example project from the trunk:
-
-[source,make]
-dep_ex1 = svn https://example.com/svn/trunk/project/ex1
-
-And this would fetch a separate example project from a
-specific commit:
-
-[source,make]
-dep_ex2 = svn svn://example.com/svn/branches/erlang-proj/ex2@264
-
-You can copy a directory from your machine using the `cp` method.
-It only takes the path to copy from:
-
-[source,make]
-dep_cowboy = cp $(HOME)/ninenines/cowboy
-
-Finally, you can use a package from the
-link:https://hex.pm/[Hex repository]:
-
-[source,make]
-dep_cowboy = hex 1.0.3
-
-==== Custom fetch methods
-
-If none of the existing methods fit your use, you can simply
-define your own. Erlang.mk will consider all variables that
-are named as `dep_fetch_$(METHOD)` to be available fetch
-methods. You can do anything inside this variable, as long
-as you create a folder named '$(DEPS_DIR)/$(call dep_name,$1)'.
-Or in layman terms, if your dependency is Cowboy, this would
-become 'deps/cowboy'.
-
-To give an example, this is what the Git method does:
-
-[source,make]
-----
-define dep_fetch_git
-	git clone -q -n -- $(call dep_repo,$1) $(DEPS_DIR)/$(call dep_name,$1); \
-	cd $(DEPS_DIR)/$(call dep_name,$1) && git checkout -q $(call dep_commit,$1);
-endef
-----
-
-Note that, like dependency information, this custom fetch method
-must be written before including 'erlang.mk'.
-
-=== How deps are fetched and built
-
-The order in which dependencies are fetched and built is well
-defined. This means that Erlang.mk will get the same applications
-regardless of the command or options being used.
-
-In tree traversal terms, where the list of dependencies is a
-tree, Erlang.mk fetches everything using the pre-order traversal
-method. The steps can be summarized like this, starting from
-the root application:
-
-. Fetch all dependencies for the application
-. Build first dependency
-. Build Nth dependency
-. Build last dependency
-
-Every time a dependency is built, these same steps are followed,
-recursively.
-
-Do note that the first step, fetching all dependencies of
-an application, is not guaranteed to be ordered. The reason
-for this is that it is not possible to have the same dependency
-listed twice in a single application, and therefore there can
-be no conflicts. Remember, this step only fetches, at no point
-are different applications built in parallel.
-
-What about conflicts between the dependencies of different
-applications? Simple. Since builds are ordered, this means
-that the first version of an application that is fetched
-will be the one that wins.
-
-This means that if project A depends on projects B and C,
-in this order, and that both B and C depend on a different
-version of D, it will always be B's version of D that wins,
-because we fetch the dependencies of B before fetching
-those from C.
-
-Similarly, if project A depends on projects B, C and D,
-regardless of the order, and A, B and C depend on a
-different version of D, it will always be A's version
-that wins, because we fetch all dependencies of A before
-fetching those from B or C.
-
-Once a dependency is built, it will not be built again by
-default. Typically dependencies do not need to be recompiled
-and this speeds up building immensely. There are a few ways
-to force recompiling a dependency however:
-
-* The dependency directory is a symbolic link; the dependency
-  will always be recompiled.
-
-* The dependency is built directly, for example with a command
-  like `make -C deps/cowlib`, or `make` in the dependency's
-  directory.
-
-* The variable `FULL` is set, for example `make FULL=1`. This
-  will force building of all dependencies. This can be added
-  to your Makefile before including 'erlang.mk'.
-
-* The file `ebin/dep_built` in the dependency is removed.
-
-=== Fetching and listing dependencies only
-
-You can fetch all dependencies recursively without building anything,
-with the `make fetch-deps` command. It follows the same rules described
-in the section above.
-
-You can list all dependencies recursively, again without building
-anything, with the `make list-deps` command. It will obviously need
-to fetch all dependencies exactly like `make fetch-deps`. Once
-everything is fetched, it prints a sorted list of absolute paths to the
-dependencies.
-
-By default, `fetch-deps` and `list-deps` work on the `BUILD_DEPS`
-and `DEPS` lists only. To also fetch/list `TEST_DEPS`, `DOC_DEPS`,
-`REL_DEPS` and/or `SHELL_DEPS`, you have two possibilities:
-
-* You can use `make fetch-test-deps`, `make fetch-doc-deps`, `make
-  fetch-rel-deps` and `make fetch-shell-deps` commands respectively.
-  If you want to list them, you can use `make list-test-deps`, `make
-  list-doc-deps`, `make list-rel-deps` and `make list-shell-deps`
-  respectively.
-* You can use `make fetch-deps` or `make list-deps` with the Makefile
-  variable `DEP_TYPES` set to a list of dependency types you want.
-  The types are `test`, `doc`, `rel` and `shell` respectively. For
-  example, you can list test and doc dependencies with `make list-deps
-  DEP_TYPES='test doc'`.
-
-Note that only first level `TEST_DEPS`, `DOC_DEPS`, `REL_DEPS` and
-`SHELL_DEPS` are included, not dependencies' one. In other word,
-`make list-test-deps` lists the `TEST_DEPS` of your project, but not
-`TEST_DEPS` of the projects yours depend on.
-
-No matter which method you use, `BUILD_DEPS` and `DEPS` are always
-included.
-
-Internally, the `make fetch-*` commands store the complete list of
-dependencies in files named `$(ERLANG_MK_RECURSIVE_DEPS_LIST)`,
-`$(ERLANG_MK_RECURSIVE_TEST_DEPS_LIST)`,
-`$(ERLANG_MK_RECURSIVE_DOC_DEPS_LIST)`,
-`$(ERLANG_MK_RECURSIVE_REL_DEPS_LIST)` and
-`$(ERLANG_MK_RECURSIVE_SHELL_DEPS_LIST)`. Those files are simply printed
-by the `make list-*` commands.
-
-`make list-*` commands are made for human beings. If you need the list
-of dependencies in a Makefile or a script, you should use the content
-of those files directly instead. The reason is that `make fetch-*` and
-`make list-*` may have unwanted content in their output, such as actual
-fetching of dependencies.
-
-=== Ignoring unwanted dependencies
-
-Sometimes, you may want to ignore dependencies entirely.
-Not even fetch them. You may want to do this because a
-project you depend on depends on an application you do
-not need (like a dependency for building documentation
-or testing). Or maybe the dependency is already installed
-on your system.
-
-To ignore a dependency, simply add it to the `IGNORE_DEPS`
-variable:
-
-[source,make]
-IGNORE_DEPS += edown proper
-
-This will only ignore dependencies that are needed for
-building. It is therefore safe to write:
-
-[source,make]
-IGNORE_DEPS += edown proper
-TEST_DEPS = proper
-
-The PropEr application will be fetched as intended when
-running `make tests` or `make check`. It will however
-not be fetched when running `make` or `make deps`.
-
-=== Dependencies directory
-
-Dependencies are fetched in '$(DEPS_DIR)'. By default this is
-the 'deps' directory. You can change this default, but you
-should only do so if it was not defined previously. Erlang.mk
-uses this variable to tell dependencies where to fetch their
-own dependencies.
-
-You will therefore need to use `?=` instead of `=`. Of course,
-if you know you will never use this project as a dependency,
-`=` will work. But to avoid it biting you later on, do this:
-
-[source,make]
-DEPS_DIR ?= $(CURDIR)/libs
-
-The `$(CURDIR)` part is important, otherwise dependencies of
-dependencies will be fetched in the wrong directory.
-
-Erlang.mk will also export the `REBAR_DEPS_DIR` variable for
-compatibility with Rebar build tools, as long as they are
-recent enough.
-
-=== Many applications in one repository
-
-In addition to the dependencies that are fetched, Erlang.mk
-also allows you to have dependencies local to your repository.
-This kind of layout is sometimes called multi-application
-repositories, or repositories with multiple applications.
-
-They work exactly the same as remote dependencies, except:
-
-* They are not fetched
-* They are not autopatched
-* They are not deleted on `make distclean`
-* They are not automatically added to the application resource file
-
-To properly fill the application resource file and compile apps in
-the right order, you will need to define the `LOCAL_DEPS` variable
-for each relevant application, the same as for OTP applications. Apps
-can depend on each other in this way, and their compilation order
-will follow the same rules as regular dependencies in `DEPS`.
-
-The top-level `LOCAL_DEPS` variable, if defined, will determine which
-apps (along with their dependencies) to build, and also which apps
-should be added to the top-level application resource file, if there
-is one. This may be useful, for example, for specifying a different
-set of apps to build for different releases. If `LOCAL_DEPS` is not
-defined, then all apps in the '$(APPS_DIR)' will be built, but none
-will be automatically added to the top-level application resource
-file.
-
-If there is a conflict between a local dependency and a
-remote dependency, then the local dependency always wins;
-an error will be triggered when trying to fetch the
-conflicting remote dependency.
-
-To start using dependencies local to the repository, simply
-create a folder named '$(APPS_DIR)'. By default, this folder
-is the 'apps/' directory.
-
-You can use Erlang.mk to bootstrap local dependencies by
-using the command `make new-app` or `make new-lib`. This
-command will create the necessary directories and bootstrap
-the application.
-
-For example, to create a full fledged OTP application as
-a local dependency:
-
-[source,bash]
-$ make new-app in=webchat
-
-Or, the same as an OTP library:
-
-[source,bash]
-$ make new-lib in=webchat
-
-Templates also work with local dependencies, from the root
-directory of the project. You do need however to tell
-Erlang.mk to create the files in the correct application:
-
-[source,bash]
-$ make new t=gen_server n=my_server in=webchat
-
-=== Repositories with no application at the root level
-
-It's possible to use Erlang.mk with only applications in
-'$(APPS_DIR)', and nothing at the root of the repository.
-Just create a folder, put the 'erlang.mk' file in it,
-write a Makefile that includes it, and start creating
-your applications.
-
-Similarly, it's possible to have a repository with only
-dependencies found in '$(DEPS_DIR)'. You just need to
-create a Makefile and specify the dependencies you want.
-This allows you to create a repository for handling the
-building of releases, for example.
-
-=== Autopatch
-
-Erlang.mk will automatically patch all the dependencies it
-fetches. It needs to do this to ensure that the dependencies
-become compatible with not only Erlang.mk, but also with
-the version of Erlang.mk that is currently used.
-
-When fetching a dependency, the following operations are
-performed:
-
-* Fetch the dependency using the configured fetch method
-* If it contains a 'configure.ac' or 'configure.in' file, run `autoreconf -Wall -vif -I m4`
-* If it contains a 'configure' script, run it
-* Run autopatch on the project
-
-Autopatch first checks if there is any project-specific patch
-enabled. There are currently three: `RABBITMQ_CLIENT_PATCH` for
-the `amqp_client` dependency (before 3.6.0), `RABBITMQ_SERVER_PATCH`
-for the `rabbit` dependency (before 3.6.0) and `ELIXIR_PATCH`
-for the `elixir` dependency.
-
-Otherwise, autopatch performs different operations depending
-on the kind of project it finds the dependency to be.
-
-* Rebar projects are automatically converted to use Erlang.mk
-as their build tool. This essentially patches Rebar out, and
-fixes and converts the project to be compatible with Erlang.mk.
-
-* Erlang.mk projects have their 'Makefile' patched, if necessary,
-to include the top-level project's Erlang.mk. This is to ensure
-that functionality works across all dependencies, even if the
-dependency's Erlang.mk is outdated. The patched Makefile
-can be safely committed if necessary.
-
-* Other Erlang projects get a small Erlang.mk Makefile
-generated automatically.
-
-* Projects with no source directory and no Makefile get an
-empty Makefile generated, for compatibility purposes.
-
-* Other projects with no Makefile are left untouched.
-
-You can add additional commands to be run immediately before
-or after autopatch is done by extending the target
-`autopatch-$(dep)::`, for example this would remove
-a module:
-
-[source,make]
-----
-autopatch-ranch::
-	rm -f $(DEPS_DIR)/ranch/src/ranch_proxy_header.erl
-----
-
-A common use case for this feature is to apply a PATCH
-file on the dependency immediately after fetching it.
-It can also be used to add compiler options, for example:
-
-[source,make]
-----
-autopatch-couchbeam::
-	printf "\nERLC_OPTS += -DWITH_JIFFY\n" >> $(DEPS_DIR)/couchbeam/Makefile
-----
-
-The commands will run before autopatch when the target is
-defined before including 'erlang.mk', and after otherwise.
-
-You can disable the replacing of the 'erlang.mk' file by
-defining the `NO_AUTOPATCH_ERLANG_MK` variable:
-
-[source,make]
-NO_AUTOPATCH_ERLANG_MK = 1
-
-You can also disable autopatch entirely for a few select
-projects using the `NO_AUTOPATCH` variable:
-
-[source,make]
-NO_AUTOPATCH = cowboy ranch cowlib
-
-=== Dealing with duplicate modules
-
-When there are duplicate modules found in both applications
-and their dependencies, some tasks may fail. Erlang expects
-modules to be unique in general.
-
-When the duplicates are found in dependencies, you will need
-to remove one of the duplicates at fetch time. To do so, you
-can add a rule similar to this to your Makefile before including
-'erlang.mk':
-
-[source,make]
-----
-DEPS_DIR = $(CURDIR)/deps
-
-deps:: $(DEPS_DIR)/cowlib
-	$(verbose) rm -f $(DEPS_DIR)/cowlib/src/cow_ws.erl
-----
-
-This must be done from the application that has this dependency.
-Only define the `DEPS_DIR` variable if necessary.
-
-=== Skipping deps
-
-It is possible to temporarily skip all dependency operations.
-This is done by defining the `SKIP_DEPS` variable. Use cases
-include being somewhere with no connection to download them,
-or perhaps a peculiar setup.
-
-A typical usage would be:
-
-[source,bash]
-$ make SKIP_DEPS=1
-
-When the variable is defined:
-
-* Dependencies will not be compiled or downloaded when required
-* The dependency directory '$(DEPS_DIR)' will not be removed on `make distclean`
-
-This variable only applies to remote dependencies.

-<p>Erlang.mk can fetch and compile the dependencies that your project requires. Erlang.mk improves upon the concepts introduced by Rebar, so they should be familiar to many seasoned Erlang developers.</p>
-<p>Erlang.mk is not a package manager, nor is it trying to be, but it does include an index of Erlang packages to make discovering useful projects easier.</p>
-<p>This chapter will explain how to use packages, add dependencies to your project or bundle them directly in a single repository.</p>
-<h2 id="_searching_packages">Searching packages</h2>
-<p>Erlang.mk gives you access to nearly 500 packages, with more being added regularly.</p>
-<p>To find a package, search for it:</p>
-<div class="listingblock"><div class="content"><!-- Generator: GNU source-highlight 3.1.8

-<pre><tt>$ make search <font color="#009900">q</font><font color="#990000">=</font>pool</tt></pre>
-</div></div>
-<p>This will return all packages matching this word, like worker pool and acceptor pool projects.</p>
-<p>You can also list everything and use regular command line tools to find what you need, for example:</p>

-<!-- everything, then link to this new chapter from here.-->
-<h2 id="_adding_dependencies_to_your_project">Adding dependencies to your project</h2>
-<p>Once you find the package you need, adding it as a dependency to your project is a one-liner:</p>
-<div class="listingblock"><div class="content"><!-- Generator: GNU source-highlight 3.1.8

-http://www.lorenzobettini.it
-http://www.gnu.org/software/src-highlite -->
-<pre><tt><font color="#009900">DEPS =</font> cowboy</tt></pre>
-</div></div>
-<p>And that&apos;s it! The next time you run <code>make</code>, Erlang.mk will fetch and compile Cowboy. Erlang.mk will also ensure Cowboy is available whenever you use the shell, run tests and any other operations.</p>
-<p>Erlang.mk will fill in the application resource file with all applications found in <code>DEPS</code>. But not all dependencies are Erlang applications, and not all dependencies need to be a runtime dependency. That&apos;s where the <code>BUILD_DEPS</code> variable comes in: it works just like <code>DEPS</code>, except the dependencies listed there will not be added as runtime dependencies.</p>
-<p>For example, you could add a parse transform project like this to make it available only at build time:</p>
-<div class="listingblock"><div class="content"><!-- Generator: GNU source-highlight 3.1.8

-http://www.lorenzobettini.it
-http://www.gnu.org/software/src-highlite -->
-<pre><tt><font color="#009900">BUILD_DEPS =</font> erlando</tt></pre>
-</div></div>
-<p>Or you could depend on a C project directly, if you are building a NIF:</p>
-<div class="listingblock"><div class="content"><!-- Generator: GNU source-highlight 3.1.8
-by Lorenzo Bettini
-http://www.lorenzobettini.it
-http://www.gnu.org/software/src-highlite -->
-<pre><tt><font color="#009900">BUILD_DEPS =</font> leveldb
-<font color="#009900">dep_leveldb =</font> git https<font color="#990000">:</font>//github.com/basho/leveldb 2.1.3</tt></pre>
-</div></div>
-<p>This dependency will be built before your application, so you could easily copy the resulting shared file into your <em>priv/</em> directory as part of the build process. More information about that in the <a href="../ports">NIFs and port drivers</a> chapter.</p>
-<p>Another variable, <code>LOCAL_DEPS</code>, allows specifying runtime dependencies which are part of Erlang/OTP itself, but also dependencies that are included in the repository. Since they are already on your system, there is no need to fetch them. Do note that there is no way to choose the version, the application used will be the one already on your system.</p>
-<p>You could depend on the Crypto application, for example:</p>

-<pre><tt><font color="#009900">LOCAL_DEPS =</font> crypto</tt></pre>
-</div></div>
-<p>Erlang.mk comes with additional types of dependencies. It has <code>TEST_DEPS</code> for dependencies used only for testing:</p>

-<pre><tt><font color="#009900">DOC_DEPS =</font> edown</tt></pre>
-</div></div>
-<p><code>REL_DEPS</code> for dependencies required to build the release, or to include extra applications in the release:</p>

-<pre><tt><font color="#009900">REL_DEPS =</font> recon</tt></pre>
-</div></div>
-<p>And <code>SHELL_DEPS</code> for dependencies to make available when running the <code>make shell</code> command:</p>

-<pre><tt><font color="#009900">SHELL_DEPS =</font> tddreloader</tt></pre>
-</div></div>
-<p>All these will be documented in more details in their respective chapters.</p>
-<p>Note that these additional types of dependencies will only be fetched after normal dependencies by default. You can force a dependency to be downloaded first by extending the target <code>deps::</code> before including <em>erlang.mk</em>, for example:</p>
-<dl><dt>deps</dt>
-<dd><p>$(CURDIR)/deps/triq</p>
-</dd>
-</dl>
-<h4 id="_modifying_the_dependency_source_or_version">Modifying the dependency source or version</h4>
-<p>By default, Erlang.mk will look into its package index to find the project you are looking for, if you only provide its name. This is this case:</p>
-<div class="listingblock"><div class="content"><!-- Generator: GNU source-highlight 3.1.8

-http://www.gnu.org/software/src-highlite -->
-<pre><tt><font color="#009900">DEPS =</font> cowboy</tt></pre>
-</div></div>
-<p>If you need a different version, you need to define another variable. There are two ways to do this, each being useful for different reasons.</p>
-<p>If you simply want to change the commit number, all you need to do is to define the <code>dep_$(DEP_NAME)_commit</code> variable. In the case of Cowboy, this would look like this:</p>
-<div class="listingblock"><div class="content"><!-- Generator: GNU source-highlight 3.1.8

-http://www.gnu.org/software/src-highlite -->
-<pre><tt><font color="#009900">DEPS =</font> cowboy
-<font color="#009900">dep_cowboy_commit =</font> 2.0.0-pre.2</tt></pre>
-</div></div>
-<p>Erlang.mk will use the package index to get all information about Cowboy, except the commit number which will be overriden.</p>
-<p>If you need to set the fetch method or repository information too, for example because you want to use your own fork, or simply because the project is missing from the index, you can define the <code>dep_$(DEP_NAME)</code> variable with everything:</p>
-<div class="listingblock"><div class="content"><!-- Generator: GNU source-highlight 3.1.8

-<font color="#009900">dep_cowboy =</font> git https<font color="#990000">:</font>//github.com/essen/cowboy 2.0.0-pre.2</tt></pre>
-</div></div>
-<p>This will fetch Cowboy from your fork at the given commit.</p>
-<h4 id="_fetch_methods">Fetch methods</h4>
-<p>Erlang.mk comes with a number of different fetch methods. You can fetch from Git, Mercurial, SVN, to name a few. There are fetch methods that will work everywhere, and fetch methods that will only work in a given environment.</p>
-<p>The following table lists all existing methods:</p>

-</tbody></table>
-<p>The <code>git</code> and <code>hg</code> methods both have a repository and commit. You can use any valid commit, tag or branch in that repository for the commit value.</p>
-<p>For example, to fetch Cowboy with tag 2.0.0-pre.2 from Git:</p>
-<div class="listingblock"><div class="content"><!-- Generator: GNU source-highlight 3.1.8

-</div></div>
-<p>Or to fetch Ehsa tag 4.0.3 from Mercurial:</p>
-<div class="listingblock"><div class="content"><!-- Generator: GNU source-highlight 3.1.8

-</div></div>
-<p>Git also comes with a concept of submodules. Erlang.mk can automatically initializes and updates submodules for dependencies, as long as they were added beforehand using <code>git submodule add</code>:</p>
-<div class="listingblock"><div class="content"><!-- Generator: GNU source-highlight 3.1.8

-</div></div>
-<p>The <code>svn</code> method only has a repository value, but that&apos;s simply because the SVN repository URL can also contain the path and commit.</p>
-<p>This would fetch an example project from the trunk:</p>

-</div></div>
-<p>You can copy a directory from your machine using the <code>cp</code> method. It only takes the path to copy from:</p>

-</div></div>
-<p>Finally, you can use a package from the <a href="https://hex.pm/">Hex repository</a>:</p>

-</div></div>
-<h4 id="_custom_fetch_methods">Custom fetch methods</h4>
-<p>If none of the existing methods fit your use, you can simply define your own. Erlang.mk will consider all variables that are named as <code>dep_fetch_$(METHOD)</code> to be available fetch methods. You can do anything inside this variable, as long as you create a folder named <em>$(DEPS_DIR)/$(call dep_name,$1)</em>. Or in layman terms, if your dependency is Cowboy, this would become <em>deps/cowboy</em>.</p>
-<p>To give an example, this is what the Git method does:</p>

-endef</tt></pre>
-</div></div>
-<p>Note that, like dependency information, this custom fetch method must be written before including <em>erlang.mk</em>.</p>
-<h2 id="_how_deps_are_fetched_and_built">How deps are fetched and built</h2>
-<p>The order in which dependencies are fetched and built is well defined. This means that Erlang.mk will get the same applications regardless of the command or options being used.</p>
-<p>In tree traversal terms, where the list of dependencies is a tree, Erlang.mk fetches everything using the pre-order traversal method. The steps can be summarized like this, starting from the root application:</p>
-<ol><li>Fetch all dependencies for the application
-</li>
-<li>Build first dependency
-</li>
-<li>Build Nth dependency
-</li>
-<li>Build last dependency
-</li>
-</ol>
-<p>Every time a dependency is built, these same steps are followed, recursively.</p>
-<p>Do note that the first step, fetching all dependencies of an application, is not guaranteed to be ordered. The reason for this is that it is not possible to have the same dependency listed twice in a single application, and therefore there can be no conflicts. Remember, this step only fetches, at no point are different applications built in parallel.</p>
-<p>What about conflicts between the dependencies of different applications? Simple. Since builds are ordered, this means that the first version of an application that is fetched will be the one that wins.</p>
-<p>This means that if project A depends on projects B and C, in this order, and that both B and C depend on a different version of D, it will always be B&apos;s version of D that wins, because we fetch the dependencies of B before fetching those from C.</p>
-<p>Similarly, if project A depends on projects B, C and D, regardless of the order, and A, B and C depend on a different version of D, it will always be A&apos;s version that wins, because we fetch all dependencies of A before fetching those from B or C.</p>
-<p>Once a dependency is built, it will not be built again by default. Typically dependencies do not need to be recompiled and this speeds up building immensely. There are a few ways to force recompiling a dependency however:</p>
-<ul><li>The dependency directory is a symbolic link; the dependency will always be recompiled.
-</li>
-<li>The dependency is built directly, for example with a command like <code>make -C deps/cowlib</code>, or <code>make</code> in the dependency&apos;s directory.
-</li>
-<li>The variable <code>FULL</code> is set, for example <code>make FULL=1</code>. This will force building of all dependencies. This can be added to your Makefile before including <em>erlang.mk</em>.
-</li>
-<li>The file <code>ebin/dep_built</code> in the dependency is removed.
-</li>
-</ul>
-<h2 id="_fetching_and_listing_dependencies_only">Fetching and listing dependencies only</h2>
-<p>You can fetch all dependencies recursively without building anything, with the <code>make fetch-deps</code> command. It follows the same rules described in the section above.</p>
-<p>You can list all dependencies recursively, again without building anything, with the <code>make list-deps</code> command. It will obviously need to fetch all dependencies exactly like <code>make fetch-deps</code>. Once everything is fetched, it prints a sorted list of absolute paths to the dependencies.</p>
-<p>By default, <code>fetch-deps</code> and <code>list-deps</code> work on the <code>BUILD_DEPS</code> and <code>DEPS</code> lists only. To also fetch/list <code>TEST_DEPS</code>, <code>DOC_DEPS</code>, <code>REL_DEPS</code> and/or <code>SHELL_DEPS</code>, you have two possibilities:</p>
-<ul><li>You can use <code>make fetch-test-deps</code>, <code>make fetch-doc-deps</code>, <code>make
-fetch-rel-deps</code> and <code>make fetch-shell-deps</code> commands respectively. If you want to list them, you can use <code>make list-test-deps</code>, <code>make
-list-doc-deps</code>, <code>make list-rel-deps</code> and <code>make list-shell-deps</code> respectively.
-</li>
-<li>You can use <code>make fetch-deps</code> or <code>make list-deps</code> with the Makefile variable <code>DEP_TYPES</code> set to a list of dependency types you want. The types are <code>test</code>, <code>doc</code>, <code>rel</code> and <code>shell</code> respectively. For example, you can list test and doc dependencies with <code>make list-deps
-DEP_TYPES=&apos;test doc&apos;</code>.
-</li>
-</ul>
-<p>Note that only first level <code>TEST_DEPS</code>, <code>DOC_DEPS</code>, <code>REL_DEPS</code> and <code>SHELL_DEPS</code> are included, not dependencies&apos; one. In other word, <code>make list-test-deps</code> lists the <code>TEST_DEPS</code> of your project, but not <code>TEST_DEPS</code> of the projects yours depend on.</p>
-<p>No matter which method you use, <code>BUILD_DEPS</code> and <code>DEPS</code> are always included.</p>
-<p>Internally, the <code>make fetch-*</code> commands store the complete list of dependencies in files named <code>$(ERLANG_MK_RECURSIVE_DEPS_LIST)</code>, <code>$(ERLANG_MK_RECURSIVE_TEST_DEPS_LIST)</code>, <code>$(ERLANG_MK_RECURSIVE_DOC_DEPS_LIST)</code>, <code>$(ERLANG_MK_RECURSIVE_REL_DEPS_LIST)</code> and <code>$(ERLANG_MK_RECURSIVE_SHELL_DEPS_LIST)</code>. Those files are simply printed by the <code>make list-*</code> commands.</p>
-<p><code>make list-*</code> commands are made for human beings. If you need the list of dependencies in a Makefile or a script, you should use the content of those files directly instead. The reason is that <code>make fetch-*</code> and <code>make list-*</code> may have unwanted content in their output, such as actual fetching of dependencies.</p>
-<h2 id="_ignoring_unwanted_dependencies">Ignoring unwanted dependencies</h2>
-<p>Sometimes, you may want to ignore dependencies entirely. Not even fetch them. You may want to do this because a project you depend on depends on an application you do not need (like a dependency for building documentation or testing). Or maybe the dependency is already installed on your system.</p>
-<p>To ignore a dependency, simply add it to the <code>IGNORE_DEPS</code> variable:</p>

-<p>The PropEr application will be fetched as intended when running <code>make tests</code> or <code>make check</code>. It will however not be fetched when running <code>make</code> or <code>make deps</code>.</p>
-<h2 id="_dependencies_directory">Dependencies directory</h2>
-<p>Dependencies are fetched in <em>$(DEPS_DIR)</em>. By default this is the <em>deps</em> directory. You can change this default, but you should only do so if it was not defined previously. Erlang.mk uses this variable to tell dependencies where to fetch their own dependencies.</p>
-<p>You will therefore need to use <code>?=</code> instead of <code>=</code>. Of course, if you know you will never use this project as a dependency, <code>=</code> will work. But to avoid it biting you later on, do this:</p>

-<pre><tt>DEPS_DIR <font color="#990000">?=</font> <font color="#009900">$(CURDIR)</font>/libs</tt></pre>
-</div></div>
-<p>The <code>$(CURDIR)</code> part is important, otherwise dependencies of dependencies will be fetched in the wrong directory.</p>
-<p>Erlang.mk will also export the <code>REBAR_DEPS_DIR</code> variable for compatibility with Rebar build tools, as long as they are recent enough.</p>
-<h2 id="_many_applications_in_one_repository">Many applications in one repository</h2>
-<p>In addition to the dependencies that are fetched, Erlang.mk also allows you to have dependencies local to your repository. This kind of layout is sometimes called multi-application repositories, or repositories with multiple applications.</p>
-<p>They work exactly the same as remote dependencies, except:</p>
-<ul><li>They are not fetched
-</li>
-<li>They are not autopatched
-</li>
-<li>They are not deleted on <code>make distclean</code>
-</li>
-<li>They are not automatically added to the application resource file
-</li>
-</ul>
-<p>To properly fill the application resource file and compile apps in the right order, you will need to define the <code>LOCAL_DEPS</code> variable for each relevant application, the same as for OTP applications. Apps can depend on each other in this way, and their compilation order will follow the same rules as regular dependencies in <code>DEPS</code>.</p>
-<p>The top-level <code>LOCAL_DEPS</code> variable, if defined, will determine which apps (along with their dependencies) to build, and also which apps should be added to the top-level application resource file, if there is one. This may be useful, for example, for specifying a different set of apps to build for different releases. If <code>LOCAL_DEPS</code> is not defined, then all apps in the <em>$(APPS_DIR)</em> will be built, but none will be automatically added to the top-level application resource file.</p>
-<p>If there is a conflict between a local dependency and a remote dependency, then the local dependency always wins; an error will be triggered when trying to fetch the conflicting remote dependency.</p>
-<p>To start using dependencies local to the repository, simply create a folder named <em>$(APPS_DIR)</em>. By default, this folder is the <em>apps/</em> directory.</p>
-<p>You can use Erlang.mk to bootstrap local dependencies by using the command <code>make new-app</code> or <code>make new-lib</code>. This command will create the necessary directories and bootstrap the application.</p>
-<p>For example, to create a full fledged OTP application as a local dependency:</p>

-<h2 id="_repositories_with_no_application_at_the_root_level">Repositories with no application at the root level</h2>
-<p>It&apos;s possible to use Erlang.mk with only applications in <em>$(APPS_DIR)</em>, and nothing at the root of the repository. Just create a folder, put the <em>erlang.mk</em> file in it, write a Makefile that includes it, and start creating your applications.</p>
-<p>Similarly, it&apos;s possible to have a repository with only dependencies found in <em>$(DEPS_DIR)</em>. You just need to create a Makefile and specify the dependencies you want. This allows you to create a repository for handling the building of releases, for example.</p>
-<h2 id="_autopatch">Autopatch</h2>
-<p>Erlang.mk will automatically patch all the dependencies it fetches. It needs to do this to ensure that the dependencies become compatible with not only Erlang.mk, but also with the version of Erlang.mk that is currently used.</p>
-<p>When fetching a dependency, the following operations are performed:</p>
-<ul><li>Fetch the dependency using the configured fetch method
-</li>
-<li>If it contains a <em>configure.ac</em> or <em>configure.in</em> file, run <code>autoreconf -Wall -vif -I m4</code>
-</li>
-<li>If it contains a <em>configure</em> script, run it
-</li>
-<li>Run autopatch on the project
-</li>
-</ul>
-<p>Autopatch first checks if there is any project-specific patch enabled. There are currently three: <code>RABBITMQ_CLIENT_PATCH</code> for the <code>amqp_client</code> dependency (before 3.6.0), <code>RABBITMQ_SERVER_PATCH</code> for the <code>rabbit</code> dependency (before 3.6.0) and <code>ELIXIR_PATCH</code> for the <code>elixir</code> dependency.</p>
-<p>Otherwise, autopatch performs different operations depending on the kind of project it finds the dependency to be.</p>
-<ul><li>Rebar projects are automatically converted to use Erlang.mk as their build tool. This essentially patches Rebar out, and fixes and converts the project to be compatible with Erlang.mk.
-</li>
-<li>Erlang.mk projects have their <em>Makefile</em> patched, if necessary, to include the top-level project&apos;s Erlang.mk. This is to ensure that functionality works across all dependencies, even if the dependency&apos;s Erlang.mk is outdated. The patched Makefile can be safely committed if necessary.
-</li>
-<li>Other Erlang projects get a small Erlang.mk Makefile generated automatically.
-</li>
-<li>Projects with no source directory and no Makefile get an empty Makefile generated, for compatibility purposes.
-</li>
-<li>Other projects with no Makefile are left untouched.
-</li>
-</ul>
-<p>You can add additional commands to be run immediately before or after autopatch is done by extending the target <code>autopatch-$(dep)::</code>, for example this would remove a module:</p>

-<h2 id="_dealing_with_duplicate_modules">Dealing with duplicate modules</h2>
-<p>When there are duplicate modules found in both applications and their dependencies, some tasks may fail. Erlang expects modules to be unique in general.</p>
-<p>When the duplicates are found in dependencies, you will need to remove one of the duplicates at fetch time. To do so, you can add a rule similar to this to your Makefile before including <em>erlang.mk</em>:</p>

-[[dialyzer]]
-== Dialyzer
-
-Dialyzer is a tool that will detect discrepancies in your
-program. It does so using a technique known as success
-typing analysis which has the advantage of providing no
-false positives. Dialyzer is able to detect type errors,
-dead code and more.
-
-Erlang.mk provides a wrapper around Dialyzer.
-
-=== How it works
-
-Dialyzer requires a PLT file to work. The PLT file contains
-the analysis information from all applications which are not
-expected to change, or rarely do. These would be all the
-dependencies of the application or applications you are
-currently working on, including standard applications in
-Erlang/OTP itself.
-
-Dialyzer can generate this PLT file. Erlang.mk includes rules
-to automatically generate the PLT file when it is missing.
-
-Once the PLT file is generated, Dialyzer can perform the
-analysis in record time.
-
-=== Configuration
-
-In a typical usage scenario, no variable needs to be set.
-The defaults should be enough. Do note however that the
-dependencies need to be set properly using the `DEPS` and
-`LOCAL_DEPS` variables.
-
-The `DIALYZER_PLT` file indicates where the PLT file will
-be written to (and read from). By default this is
-'$(PROJECT).plt' in the project's directory. Note that
-the `DIALYZER_PLT` variable is exported and is understood
-by Dialyzer directly.
-
-The `PLT_APPS` variable can be used to add additional
-applications to the PLT. You can either list application
-names or paths to these applications.
-
-Erlang.mk defines two variables for specifying options
-for the analysis: `DIALYZER_DIRS` and `DIALYZER_OPTS`.
-The former one defines which directories should be part
-of the analysis. The latter defines what extra warnings
-Dialyzer should report.
-
-Note that Erlang.mk enables the race condition warnings
-by default. As it can take considerably large resources
-to run, you may want to disable it on larger projects.
-
-=== Usage
-
-To perform an analysis, run the following command:
-
-[source,bash]
-$ make dialyze
-
-This will create the PLT file if it doesn't exist.
-
-The analysis will also be performed when you run the
-following command, alongside tests:
-
-[source,bash]
-$ make check
-
-You can use the `plt` target to create the PLT file if
-it doesn't exist. This is normally not necessary as
-Dialyzer creates it automatically.
-
-The PLT file will be removed when you run `make distclean`.
-
-=== Dialyzing beam files
-
-By default Erlang.mk will run Dialyzer against the source
-code. It is possible to configure Erlang.mk to use the
-compiled source files instead. This is done using the
-`DIALYZER_DIRS` variable:
-
-[source,make]
-DIALYZER_DIRS = -r ebin
-
-This value must be set before including Erlang.mk to
-function properly.

-<h1 class="lined-header"><span>Dialyzer</span></h1>
-
-<p>Dialyzer is a tool that will detect discrepancies in your program. It does so using a technique known as success typing analysis which has the advantage of providing no false positives. Dialyzer is able to detect type errors, dead code and more.</p>
-<p>Erlang.mk provides a wrapper around Dialyzer.</p>
-<h2 id="_how_it_works">How it works</h2>
-<p>Dialyzer requires a PLT file to work. The PLT file contains the analysis information from all applications which are not expected to change, or rarely do. These would be all the dependencies of the application or applications you are currently working on, including standard applications in Erlang/OTP itself.</p>
-<p>Dialyzer can generate this PLT file. Erlang.mk includes rules to automatically generate the PLT file when it is missing.</p>
-<p>Once the PLT file is generated, Dialyzer can perform the analysis in record time.</p>
-<h2 id="_configuration">Configuration</h2>
-<p>In a typical usage scenario, no variable needs to be set. The defaults should be enough. Do note however that the dependencies need to be set properly using the <code>DEPS</code> and <code>LOCAL_DEPS</code> variables.</p>
-<p>The <code>DIALYZER_PLT</code> file indicates where the PLT file will be written to (and read from). By default this is <em>$(PROJECT).plt</em> in the project&apos;s directory. Note that the <code>DIALYZER_PLT</code> variable is exported and is understood by Dialyzer directly.</p>
-<p>The <code>PLT_APPS</code> variable can be used to add additional applications to the PLT. You can either list application names or paths to these applications.</p>
-<p>Erlang.mk defines two variables for specifying options for the analysis: <code>DIALYZER_DIRS</code> and <code>DIALYZER_OPTS</code>. The former one defines which directories should be part of the analysis. The latter defines what extra warnings Dialyzer should report.</p>
-<p>Note that Erlang.mk enables the race condition warnings by default. As it can take considerably large resources to run, you may want to disable it on larger projects.</p>
-<h2 id="_usage">Usage</h2>
-<p>To perform an analysis, run the following command:</p>
-<div class="listingblock"><div class="content"><!-- Generator: GNU source-highlight 3.1.8
-by Lorenzo Bettini
-http://www.lorenzobettini.it
-http://www.gnu.org/software/src-highlite -->
-<pre><tt>$ make dialyze</tt></pre>
-</div></div>
-<p>This will create the PLT file if it doesn&apos;t exist.</p>
-<p>The analysis will also be performed when you run the following command, alongside tests:</p>
-<div class="listingblock"><div class="content"><!-- Generator: GNU source-highlight 3.1.8
-by Lorenzo Bettini
-http://www.lorenzobettini.it
-http://www.gnu.org/software/src-highlite -->
-<pre><tt>$ make check</tt></pre>
-</div></div>
-<p>You can use the <code>plt</code> target to create the PLT file if it doesn&apos;t exist. This is normally not necessary as Dialyzer creates it automatically.</p>
-<p>The PLT file will be removed when you run <code>make distclean</code>.</p>
-<h2 id="_dialyzing_beam_files">Dialyzing beam files</h2>
-<p>By default Erlang.mk will run Dialyzer against the source code. It is possible to configure Erlang.mk to use the compiled source files instead. This is done using the <code>DIALYZER_DIRS</code> variable:</p>
-<div class="listingblock"><div class="content"><!-- Generator: GNU source-highlight 3.1.8
-by Lorenzo Bettini
-http://www.lorenzobettini.it
-http://www.gnu.org/software/src-highlite -->
-<pre><tt><font color="#009900">DIALYZER_DIRS =</font> -r ebin</tt></pre>
-</div></div>
-<p>This value must be set before including Erlang.mk to function properly.</p>

-[[edoc]]
-== EDoc comments
-
-Erlang.mk provides a thin wrapper on top of EDoc, an application
-that generates documentation based on comments found in modules.
-
-=== Writing EDoc comments
-
-The http://www.erlang.org/doc/apps/edoc/chapter.html[EDoc user guide]
-explains everything you need to know about EDoc comments.
-
-=== Configuration
-
-The `EDOC_OPTS` variable allows you to specify additional
-EDoc options. Options are documented in the
-http://www.erlang.org/doc/man/edoc.html#run-2[EDoc manual].
-
-A common use for this variable is to enable Markdown in doc
-comments, using the `edown` application:
-
-[source,make]
-DOC_DEPS = edown
-EDOC_OPTS = {doclet, edown_doclet}
-
-=== Usage
-
-To build all documentation, you would typically use:
-
-[source,bash]
-$ make docs
-
-Do note, however, that EDoc comments will only be generated
-automatically if the 'doc/overview.edoc' file exists. If you
-do not want that file and still want to generate doc comments,
-two solutions are available.
-
-You can generate EDoc documentation directly:
-
-[source,bash]
-$ make edoc
-
-You can enable automatic generation on `make docs` by adding
-the following to your Makefile:
-
-[source,make]
-----
-docs:: edoc
-----
-
-=== Running EDoc on all applications
-
-In a multi-application project you may want to run EDoc
-against all applications at the same time, instead of
-against each applications independently. To do so, you
-need to configure the `EDOC_SRC_DIRS` at the end of
-your Makefile, after including 'erlang.mk':
-
-[source,make]
-----
-EDOC_SRC_DIRS = $(ALL_APPS_DIRS)

-[[escript]]
-== Escripts
-
-Escripts are an alternative to release. They are meant to be
-used for small command line executables written in Erlang.
-
-They are not self-contained, unlike xref:relx[releases].
-Erlang must be installed for them to run. This however means
-that they are fairly small compared to releases.
-
-For self-contained executables, check xref:sfx[self-extracting releases].
-
-=== Requirements
-
-Erlang.mk uses `p7zip` by default to generate the escript
-archive. Make sure it is installed. On most systems the
-package is named `p7zip`; on Ubuntu you need `p7zip-full`.
-
-If `p7zip` is unavailable, `zip` may be used by setting
-the `ESCRIPT_ZIP` variable. For example:
-
-[source,bash]
-$ make escript ESCRIPT_ZIP=zip
-
-=== Generating an escript
-
-Run the following command to generate an escript:
-
-[source,bash]
-$ make escript
-
-This will by default create an escript with the same name as
-the project, in the project's directory. If the project is
-called `relx` then the escript will be in `./relx`.
-
-You can run the escript as you would any executable:
-
-[source,bash]
-$ ./relx
-
-=== Configuration
-
-You can change the name of the escript by setting `ESCRIPT_NAME`.
-The name determines both the default output file name and the
-entry module containing the function `main/1`.
-
-`ESCRIPT_FILE` can be set if you need a different file name
-or location.
-
-The escript header can be entirely customized. The first line
-is the shebang, set by `ESCRIPT_SHEBANG`. The second line is
-a comment, set by `ESCRIPT_COMMENT`. The third line is the
-arguments the VM will use when running the escript, set by
-`ESCRIPT_EMU_ARGS`.
-
-Finally, `ESCRIPT_ZIP` can be set to customize the command used
-to create the zip file. Read on for more information.
-
-=== Extra files
-
-Generating an escript is a two-part process. First, a zip file
-is created with the contents of the escript. Then a header is
-added to this file to create the escript.
-
-It is possible to add commands that will be executed between
-the two steps. You can for example add extra files to the zip
-archive:
-
-[source,make]
-----
-escript-zip::
-    $(verbose) $(ESCRIPT_ZIP) $(ESCRIPT_ZIP_FILE) priv/templates/*
-----
-
-The `ESCRIPT_ZIP` variable contains the command to run to add
-files to the zip archive `ESCRIPT_ZIP_FILE`.
-
-=== Optimizing for size
-
-Erlang.mk will by default compile BEAM files with debug
-information. You may want to disable this behavior to obtain

-
-<p>Escripts are an alternative to release. They are meant to be used for small command line executables written in Erlang.</p>
-<p>They are not self-contained, unlike <a href="../relx">releases</a>. Erlang must be installed for them to run. This however means that they are fairly small compared to releases.</p>
-<p>For self-contained executables, check <a href="../sfx">self-extracting releases</a>.</p>
-<h2 id="_requirements">Requirements</h2>
-<p>Erlang.mk uses <code>p7zip</code> by default to generate the escript archive. Make sure it is installed. On most systems the package is named <code>p7zip</code>; on Ubuntu you need <code>p7zip-full</code>.</p>
-<p>If <code>p7zip</code> is unavailable, <code>zip</code> may be used by setting the <code>ESCRIPT_ZIP</code> variable. For example:</p>

-<pre><tt>$ make escript</tt></pre>
-</div></div>
-<p>This will by default create an escript with the same name as the project, in the project&apos;s directory. If the project is called <code>relx</code> then the escript will be in <code>./relx</code>.</p>
-<p>You can run the escript as you would any executable:</p>

-<pre><tt>$ <font color="#990000">.</font>/relx</tt></pre>
-</div></div>
-<h2 id="_configuration">Configuration</h2>
-<p>You can change the name of the escript by setting <code>ESCRIPT_NAME</code>. The name determines both the default output file name and the entry module containing the function <code>main/1</code>.</p>
-<p><code>ESCRIPT_FILE</code> can be set if you need a different file name or location.</p>
-<p>The escript header can be entirely customized. The first line is the shebang, set by <code>ESCRIPT_SHEBANG</code>. The second line is a comment, set by <code>ESCRIPT_COMMENT</code>. The third line is the arguments the VM will use when running the escript, set by <code>ESCRIPT_EMU_ARGS</code>.</p>
-<p>Finally, <code>ESCRIPT_ZIP</code> can be set to customize the command used to create the zip file. Read on for more information.</p>
-<h2 id="_extra_files">Extra files</h2>
-<p>Generating an escript is a two-part process. First, a zip file is created with the contents of the escript. Then a header is added to this file to create the escript.</p>
-<p>It is possible to add commands that will be executed between the two steps. You can for example add extra files to the zip archive:</p>

-</div></div>
-<p>The <code>ESCRIPT_ZIP</code> variable contains the command to run to add files to the zip archive <code>ESCRIPT_ZIP_FILE</code>.</p>
-<h2 id="_optimizing_for_size">Optimizing for size</h2>
-<p>Erlang.mk will by default compile BEAM files with debug information. You may want to disable this behavior to obtain smaller escript files. Simply set <code>ERLC_OPTS</code> to a value that does not include <code>+debug_info</code>.</p>

-[[eunit]]
-== EUnit
-
-EUnit is the tool of choice for unit testing. Erlang.mk
-automates a few things on top of EUnit, including the
-discovery and running of unit tests.
-
-=== Writing tests
-
-The http://www.erlang.org/doc/apps/eunit/chapter.html[EUnit user guide]
-is the best place to learn how to write tests. Of note is
-that all functions ending with `_test` or `_test_` will be
-picked up as EUnit test cases.
-
-Erlang.mk will automatically pick up tests found in any of
-the Erlang modules of your application. It will also pick up
-tests located in the '$(TEST_DIR)' directory, which defaults
-to 'test/'.
-
-It is generally a good practice to hide test code from
-the code you ship to production. With Erlang.mk, you can
-do this thanks to the `TEST` macro. It is only defined
-when running tests:
-
-[source,erlang]
-----
--ifdef(TEST).
-
-%% Insert tests here.
-
--endif.
-----
-
-Be careful, however, if you include the EUnit header file,
-as it also defines the `TEST` macro. Make sure to only include
-it inside an `ifdef` block, otherwise tests will always be
-compiled.
-
-[source,erlang]
-----
--ifdef(TEST).
-
--include_lib(\"eunit/include/eunit.hrl\").
-
-%% Insert tests here.
-
--endif.
-----
-
-Erlang.mk will automatically recompile your code when you
-perform a normal build after running tests, and vice versa.
-
-=== Configuration
-
-The `EUNIT_OPTS` variable allows you to specify additional
-EUnit options. Options are documented in the
-http://www.erlang.org/doc/man/eunit.html#test-2[EUnit manual].
-At the time of writing, the only available option is `verbose`:
-
-[source,make]
-EUNIT_OPTS = verbose
-
-The `EUNIT_ERL_OPTS` variable allows you to specify options
-to be passed to `erl` when running EUnit tests. For example,
-you can load the 'vm.args' and 'sys.config' files:
-
-[source,make]
-EUNIT_ERL_OPTS = -args_file config/vm.args -config config/sys.config
-
-=== Usage
-
-To run all tests (including EUnit):
-
-[source,bash]
-$ make tests
-
-To run all tests and static checks (including EUnit):
-
-[source,bash]
-$ make check
-
-You can also run EUnit separately:
-
-[source,bash]
-$ make eunit
-
-EUnit will be quiet by default, only outputting errors.
-You can easily make it verbose for a single invocation:
-
-[source,bash]
-$ make eunit EUNIT_OPTS=verbose
-
-Erlang.mk allows you to run all tests from a specific
-module, or a specific test case from that module, using
-the variable `t`.
-
-For example, to run all tests from the `cow_http_hd`
-module (instead of all tests from the entire project),
-one could write:
-
-[source,bash]
-$ make eunit t=cow_http_hd
-
-Similarly, to run a specific test case:
-
-[source,bash]
-$ make eunit t=cow_http_hd:parse_accept_test_
-
-To do the same against a multi-application repository,
-you can use the `-C` option:
-
-[source,bash]
-$ make -C apps/my_app eunit t=my_module:hello_test
-
-Note that this also applies to dependencies. From Cowboy,
-you can run the following directly:
-
-[source,bash]
-$ make -C deps/cowlib eunit t=cow_http_hd
-
-Finally, xref:coverage[code coverage] is available,
-but covered in its own chapter.

-[[plugins_usage]]
-== External plugins
-
-It is often convenient to be able to keep the build files
-used by all your projects in one place. Those files could
-be Makefiles, configuration files, templates and more.
-
-Erlang.mk allows you to automatically load plugins from
-dependencies. Plugins can do anything, including defining
-new variables, defining file templates, hooking themselves
-inside the normal Erlang.mk processing or even adding new
-rules.
-
-You can load plugins using one of two methods. You can
-either load all plugins from a dependency, or just one.
-We will also cover conventions about writing external
-plugins.
-
-=== Loading all plugins from a dependency
-
-To load plugins from a dependency, all you need to do is add
-the dependency name to `DEP_PLUGINS` in addition to the list
-of dependencies.
-
-For example, if you have `cowboy` in `DEPS`, add `cowboy` in
-`DEP_PLUGINS` also:
-
-[source,make]
-DEPS = cowboy
-DEP_PLUGINS = cowboy
-
-This will load the file 'plugins.mk' in the root folder of
-the Cowboy repository.
-
-=== Loading one plugin from a dependency
-
-Now that we know how to load all plugins, let's take a look
-at how to load one specific plugin from a dependency.
-
-To do this, instead of writing only the name of the dependency,
-we will write its name and the path to the plugin file. This
-means that writing `DEP_PLUGINS = cowboy` is equivalent to
-writing `DEP_PLUGINS = cowboy/plugins.mk`.
-
-Knowing this, if we were to load the plugin 'mk/dist.mk'
-from Cowboy and no other, we would write the following in
-our Makefile:
-
-[source,make]
-DEPS = cowboy
-DEP_PLUGINS = cowboy/mk/dist.mk
-
-=== Writing external plugins
-
-The 'plugins.mk' file is a convention. It is meant to load
-all the plugins from the dependency. The code for the plugin
-can be written directly in 'plugins.mk' or be separate.
-
-If you are providing more than one plugin with your repository,
-the recommended way is to create one file per plugin in the
-'mk/' folder in your repository, and then include those
-individual plugins in 'plugins.mk'.
-
-For example, if you have two plugins 'mk/dist.mk' and
-'mk/templates.mk', you could write the following 'plugins.mk'
-file:
-
-[source,make]
-THIS := $(dir $(realpath $(lastword $(MAKEFILE_LIST))))
-include $(THIS)/mk/dist.mk
-include $(THIS)/mk/templates.mk
-
-The `THIS` variable is required to relatively include files.
-
-This allows users to not only be able to select individual
-plugins, but also select all plugins from the dependency
-in one go if they wish to do so.
-
-Plugins can include some help text by extending the target
-`help-plugins`:
-
-[source,make]
-----
-help-plugins::
-	$(verbose) printf "%s\n" "" "Run benchmark: $(MAKE) perfs"
-----
-
-=== Early-stage plugins
-
-Plugins declared in `DEP_PLUGINS` are loaded near the end of Erlang.mk.
-That's why you have access to all previously initialized variables.
-However, if you want your plugin to add common dependencies to
-your applications, a regular is loaded too late in the process.
-You need to use "Early-stage plugins". They are declared using the
-`DEP_EARLY_PLUGINS` variable instead. Plugins listed in this variable
-are loaded near the beginning of Erlang.mk Otherwise, they work exactly
-the same.
-
-If you only give the name of a dependency, the default file loaded is
-'early-plugins.mk'. You can specify a filename exactly like you would
-have done it with regular plugins.
-
-[source,make]
-# In your application's Makefile
-BUILD_DEPS = common_deps
-DEP_EARLY_PLUGINS = common_deps
-
-[source,make]
-# In the plugin's early-plugins.mk
-DEPS += cowboy
-TEST_DEPS = ct_helper
-dep_ct_helper = git https://github.com/ninenines/ct_helper master
-
-=== Loading  plugins local to the application
-
-If the Erlang.mk plugin lives in the same directory or repository as your
-application or library, then you can load it exactly like an external
-plugin: the dependency name is simply the name of your application or
-library.
-
-For example, the following Makefile loads a plugin in the 'mk'
-subdirectory:
-
-[source,make]
-DEP_PLUGINS = $(PROJECT)/mk/dist.mk
-
-This also works with early-stage plugins:
-
-[source,make]
-DEP_EARLY_PLUGINS = $(PROJECT)/mk/variables.mk
-
-Like external plugins, if you do not specify the path to the plugin, it
-defaults to 'plugins.mk' or 'early-plugins.mk', located at the root of
-your application:
-
-[source,make]
-# Loads ./early-plugins.mk
-DEP_EARLY_PLUGINS = $(PROJECT)
-# Loads ./plugins.mk
-DEP_PLUGINS = $(PROJECT)

-[[getting_started]]
-== Getting started
-
-This chapter explains how to get started using Erlang.mk.
-
-=== Creating a folder for your project
-
-The first step is always to create a new folder that will
-contain your project.
-
-[source,bash]
-$ mkdir hello_joe
-$ cd hello_joe
-
-Most people tend to put all their projects side by side in
-a common folder. We recommend keeping an organization similar
-to your remote repositories. For example, for GitHub users,
-put all your projects in a common folder with the same name
-as your username. For example '$HOME/ninenines/cowboy' for
-the Cowboy project.
-
-=== Downloading Erlang.mk
-
-At the time of writing, Erlang.mk is unlikely to be present
-in your Erlang distribution, or even in your OS packages.
-
-The next step is therefore to download it:
-
-[source,bash]
-$ wget https://erlang.mk/erlang.mk
-
-Or:
-
-[source,bash]
-$ curl -O https://erlang.mk/erlang.mk
-
-Alternatively, just https://erlang.mk/erlang.mk[click on this link].
-
-Make sure you put the file inside the folder we created previously.
-
-=== Getting started with OTP applications
-
-An OTP application is an Erlang application that has a supervision
-tree. In other words, it will always have processes running.
-
-This kind of project can be automatically generated by Erlang.mk.
-All you need to do is use the `bootstrap` target:
-
-[source,bash]
-$ make -f erlang.mk bootstrap
-
-Something similar to the following snippet will then appear
-on your screen:
-
-[source,bash]
-----
-git clone https://github.com/ninenines/erlang.mk .erlang.mk.build
-Cloning into '.erlang.mk.build'...
-remote: Counting objects: 4035, done.
-remote: Compressing objects: 100% (12/12), done.

-Resolving deltas: 100% (2442/2442), done.
-Checking connectivity... done.
-if [ -f build.config ]; then cp build.config .erlang.mk.build; fi
-cd .erlang.mk.build && make
-make[1]: Entering directory '/home/essen/tmp/hello_joe/.erlang.mk.build'
-awk 'FNR==1 && NR!=1{print ""}1' core/core.mk index/*.mk core/index.mk core/deps.mk plugins/protobuffs.mk core/erlc.mk core/docs.mk core/test.mk plugins/asciidoc.mk plugins/bootstrap.mk plugins/c_src.mk plugins/ci.mk plugins/ct.mk plugins/dialyzer.mk plugins/edoc.mk plugins/elvis.mk plugins/erlydtl.mk plugins/escript.mk plugins/eunit.mk plugins/relx.mk plugins/shell.mk plugins/triq.mk plugins/xref.mk plugins/cover.mk \
-	| sed 's/^ERLANG_MK_VERSION = .*/ERLANG_MK_VERSION = 1.2.0-642-gccd2b9f/' > erlang.mk
-make[1]: Leaving directory '/home/essen/tmp/hello_joe/.erlang.mk.build'
-cp .erlang.mk.build/erlang.mk ./erlang.mk
-rm -rf .erlang.mk.build
-----
-
-This is Erlang.mk bootstrapping itself. Indeed, the file you
-initially downloaded contains nothing more than the code needed
-to bootstrap. This operation is done only once. Consult the
-xref:updating[Updating Erlang.mk] chapter for more
-information.
-
-Of course, the generated project can now be compiled:
-
-[source,bash]
-$ make
-
-Cheers!
-
-=== Getting started with OTP libraries
-
-An OTP library is an Erlang application that has no supervision
-tree. In other words, it is nothing but modules.
-
-This kind of project can also be generated by Erlang.mk, using
-the `bootstrap-lib` target:
-
-[source,bash]
-$ make -f erlang.mk bootstrap-lib
-
-Erlang.mk will once again bootstrap itself and generate all
-the files for your project. You can now compile it:
-
-[source,bash]
-$ make
-
-Enjoy!
-
-=== Getting started with OTP releases
-
-An OTP release is the combination of the Erlang RunTime System (ERTS)
-along with all the libraries and files that your node will need
-to run. It is entirely self contained, and can often be sent as-is
-to your production system and run without any extra setup.
-
-Erlang.mk can of course bootstrap your project to generate releases.
-You can use the `bootstrap-rel` target for this purpose:
-
-[source,bash]
-$ make bootstrap-rel
-
-This target can be combined with `bootstrap` or `bootstrap-lib` to
-create a project that will build a release:
-
-[source,bash]
-$ make -f erlang.mk bootstrap-lib bootstrap-rel
-
-It is often very useful to keep the top-level project for
-commands useful during operations, and put the components
-of the system in separate applications that you will then
-depend on. Consult the xref:deps[Packages and dependencies]
-chapter for more information.
-
-When you run `make` from now on, Erlang.mk will compile your
-project and build the release:
-
-[source,bash]
-$ make
- APP    hello_joe.app.src
- GEN    distclean-relx-rel
- GEN    /home/essen/tmp/hello_joe/relx
-===> Starting relx build process ...
-===> Resolving OTP Applications from directories:
-          /home/essen/tmp/hello_joe/ebin
-          /usr/lib/erlang/lib
-          /home/essen/tmp/hello_joe/deps
-===> Resolved hello_joe_release-1
-===> Including Erts from /usr/lib/erlang
-===> release successfully created!
-
-The first time you run this command, Erlang.mk will download
-_relx_, the release building tool. So don't worry if you see
-more output than above.
-
-If building the release is slow, no need to upgrade your
-hardware just yet. Just consult the xref:relx[Releases]
-chapter for various tips to speed up build time during
-development.
-
-You can start the release using the './_rel/hello_joe_release/bin/hello_joe_release'
-script, or simply run `make run`. The latter will also compile
-your project and build the release if it wasn't already:
-
-[source,bash]
-----
-$ make run
- APP    hello_joe.app.src
- GEN    distclean-relx-rel
-===> Starting relx build process ...
-===> Resolving OTP Applications from directories:

-----
-
-Simple as that!
-
-=== Getting started from scratch
-
-If you already have an application, or you want to have full
-control over what files will be created, you can setup Erlang.mk
-manually.
-
-Erlang.mk is very easy to setup: all that you need to do is to
-create a folder, put Erlang.mk in it, and write a one line
-Makefile containing:
-
-[source,make]
-include erlang.mk
-
-For a step by step:
-
-[source,bash]
-----
-$ mkdir hello_joe
-$ cd hello_joe
-$ curl https://erlang.mk/erlang.mk -o erlang.mk
-$ echo "include erlang.mk" > Makefile
-$ make
-----
-
-From that point onward you can create an `src/` folder or start
-using templates.
-
-=== Using spaces instead of tabs
-
-Erlang.mk defaults to tabs when creating files from templates.
-This is in part because of a personal preference, and in part
-because it is much easier to convert tabs to spaces than the
-opposite.
-
-Use the `SP` variable if you prefer spaces. Set it to the number
-of spaces per indentation level you want.
-
-For example, if you prefer two spaces per indentation level:
-
-[source,bash]
-$ make -f erlang.mk bootstrap SP=2
-
-When you bootstrap the project initially, the variable automatically
-gets added to the Makefile, so you only need to provide it when
-you get started.
-
-=== Using templates
-
-It is no secret that Erlang's OTP behaviors tend to have some
-boilerplate. It is rarely an issue of course, except when
-creating new modules. That's why Erlang.mk not only comes with
-templates for generating projects, but also individual modules!
-
-You can list all available templates with the `list-templates`
-target:
-
-[source,bash]
-$ make list-templates
-Available templates: cowboy_http cowboy_loop cowboy_rest cowboy_ws gen_fsm gen_server gen_statem ranch_protocol supervisor
-
-To generate a module, let's say a `gen_server`, all you need to
-do is to call `make new` with the appropriate arguments:
-
-[source,bash]
-$ make new t=gen_server n=my_server
-
-This will create a module located in 'src/my_server.erl'
-using the `gen_server` template.
-
-This module is automatically compiled the next time you run
-`make`:
-
-[source,bash]
-$ make
- ERLC   my_server.erl
- APP    hello_joe.app.src
-
-All that's left to do is to open it in your favorite editor
-and make it do something!
-
-=== Hiding Erlang.mk from git
-
-Erlang.mk is a large text file. It can easily take a large part of
-a `git diff` or a `git grep` command. You can avoid this by telling
-Git that 'erlang.mk' is a binary file.
-
-Add this to your '.gitattributes' file. This is a file that you
-can create at the root of your repository:
-
-----
-erlang.mk -diff
-----
-
-The 'erlang.mk' file will still appear in diffs and greps, but
-as a binary file, meaning its contents won't be shown by default
-anymore.
-
-=== Getting help
-
-During development, if you don't remember the name of a target,
-you can always run `make help`:
-
-[source,bash]
-----
-$ make help

-<p>This chapter explains how to get started using Erlang.mk.</p>
-<h2 id="_creating_a_folder_for_your_project">Creating a folder for your project</h2>
-<p>The first step is always to create a new folder that will contain your project.</p>
-<div class="listingblock"><div class="content"><!-- Generator: GNU source-highlight 3.1.8

-http://www.gnu.org/software/src-highlite -->
-<pre><tt>$ mkdir hello_joe
-$ cd hello_joe</tt></pre>
-</div></div>
-<p>Most people tend to put all their projects side by side in a common folder. We recommend keeping an organization similar to your remote repositories. For example, for GitHub users, put all your projects in a common folder with the same name as your username. For example <em>$HOME/ninenines/cowboy</em> for the Cowboy project.</p>
-<h2 id="_downloading_erlang_mk">Downloading Erlang.mk</h2>
-<p>At the time of writing, Erlang.mk is unlikely to be present in your Erlang distribution, or even in your OS packages.</p>
-<p>The next step is therefore to download it:</p>

-</div></div>
-<p>Or:</p>

-</div></div>
-<p>Alternatively, just <a href="https://erlang.mk/erlang.mk">click on this link</a>.</p>
-<p>Make sure you put the file inside the folder we created previously.</p>
-<h2 id="_getting_started_with_otp_applications">Getting started with OTP applications</h2>
-<p>An OTP application is an Erlang application that has a supervision tree. In other words, it will always have processes running.</p>
-<p>This kind of project can be automatically generated by Erlang.mk. All you need to do is use the <code>bootstrap</code> target:</p>

-<p>This is Erlang.mk bootstrapping itself. Indeed, the file you initially downloaded contains nothing more than the code needed to bootstrap. This operation is done only once. Consult the <a href="../updating">Updating Erlang.mk</a> chapter for more information.</p>
-<p>Of course, the generated project can now be compiled:</p>

-<p>An OTP library is an Erlang application that has no supervision tree. In other words, it is nothing but modules.</p>
-<p>This kind of project can also be generated by Erlang.mk, using the <code>bootstrap-lib</code> target:</p>

-<h2 id="_getting_started_with_otp_releases">Getting started with OTP releases</h2>
-<p>An OTP release is the combination of the Erlang RunTime System (ERTS) along with all the libraries and files that your node will need to run. It is entirely self contained, and can often be sent as-is to your production system and run without any extra setup.</p>
-<p>Erlang.mk can of course bootstrap your project to generate releases. You can use the <code>bootstrap-rel</code> target for this purpose:</p>
-<div class="listingblock"><div class="content"><!-- Generator: GNU source-highlight 3.1.8
-by Lorenzo Bettini
-http://www.lorenzobettini.it
-http://www.gnu.org/software/src-highlite -->
-<pre><tt>$ make bootstrap-rel</tt></pre>
-</div></div>
-<p>This target can be combined with <code>bootstrap</code> or <code>bootstrap-lib</code> to create a project that will build a release:</p>
-<div class="listingblock"><div class="content"><!-- Generator: GNU source-highlight 3.1.8

-http://www.gnu.org/software/src-highlite -->
-<pre><tt>$ make -f erlang<font color="#990000">.</font>mk bootstrap-lib bootstrap-rel</tt></pre>
-</div></div>
-<p>It is often very useful to keep the top-level project for commands useful during operations, and put the components of the system in separate applications that you will then depend on. Consult the <a href="../deps">Packages and dependencies</a> chapter for more information.</p>
-<p>When you run <code>make</code> from now on, Erlang.mk will compile your project and build the release:</p>

-<p>The first time you run this command, Erlang.mk will download <em>relx</em>, the release building tool. So don&apos;t worry if you see more output than above.</p>
-<p>If building the release is slow, no need to upgrade your hardware just yet. Just consult the <a href="../relx">Releases</a> chapter for various tips to speed up build time during development.</p>
-<p>You can start the release using the <em>./_rel/hello_joe_release/bin/hello_joe_release</em> script, or simply run <code>make run</code>. The latter will also compile your project and build the release if it wasn&apos;t already:</p>

-<p>Simple as that!</p>
-<h2 id="_getting_started_from_scratch">Getting started from scratch</h2>
-<p>If you already have an application, or you want to have full control over what files will be created, you can setup Erlang.mk manually.</p>
-<p>Erlang.mk is very easy to setup: all that you need to do is to create a folder, put Erlang.mk in it, and write a one line Makefile containing:</p>

-<pre><tt>include erlang.mk</tt></pre>
-</div></div>
-<p>For a step by step:</p>
-<div class="listingblock"><div class="content"><!-- Generator: GNU source-highlight 3.1.8

-<pre><tt>$ mkdir hello_joe
-$ cd hello_joe
-$ curl https<font color="#990000">:</font>//erlang<font color="#990000">.</font>mk/erlang<font color="#990000">.</font>mk -o erlang<font color="#990000">.</font>mk
-$ echo <font color="#FF0000">"include erlang.mk"</font> <font color="#990000">&gt;</font> Makefile
-$ make</tt></pre>
-</div></div>
-<p>From that point onward you can create an <code>src/</code> folder or start using templates.</p>
-<h2 id="_using_spaces_instead_of_tabs">Using spaces instead of tabs</h2>
-<p>Erlang.mk defaults to tabs when creating files from templates. This is in part because of a personal preference, and in part because it is much easier to convert tabs to spaces than the opposite.</p>
-<p>Use the <code>SP</code> variable if you prefer spaces. Set it to the number of spaces per indentation level you want.</p>
-<p>For example, if you prefer two spaces per indentation level:</p>
-<div class="listingblock"><div class="content"><!-- Generator: GNU source-highlight 3.1.8

-</div></div>
-<p>When you bootstrap the project initially, the variable automatically gets added to the Makefile, so you only need to provide it when you get started.</p>
-<h2 id="_using_templates">Using templates</h2>
-<p>It is no secret that Erlang&apos;s OTP behaviors tend to have some boilerplate. It is rarely an issue of course, except when creating new modules. That&apos;s why Erlang.mk not only comes with templates for generating projects, but also individual modules!</p>
-<p>You can list all available templates with the <code>list-templates</code> target:</p>

-Available templates<font color="#990000">:</font> cowboy_http cowboy_loop cowboy_rest cowboy_ws gen_fsm gen_server gen_statem ranch_protocol supervisor</tt></pre>
-</div></div>
-<p>To generate a module, let&apos;s say a <code>gen_server</code>, all you need to do is to call <code>make new</code> with the appropriate arguments:</p>

-</div></div>
-<p>This will create a module located in <em>src/my_server.erl</em> using the <code>gen_server</code> template.</p>
-<p>This module is automatically compiled the next time you run <code>make</code>:</p>

-</div></div>
-<p>All that&apos;s left to do is to open it in your favorite editor and make it do something!</p>
-<h2 id="_hiding_erlang_mk_from_git">Hiding Erlang.mk from git</h2>
-<p>Erlang.mk is a large text file. It can easily take a large part of a <code>git diff</code> or a <code>git grep</code> command. You can avoid this by telling Git that <em>erlang.mk</em> is a binary file.</p>
-<p>Add this to your <em>.gitattributes</em> file. This is a file that you can create at the root of your repository:</p>
-<div class="listingblock"><div class="content"><pre>erlang.mk -diff</pre></div></div>
-<p>The <em>erlang.mk</em> file will still appear in diffs and greps, but as a binary file, meaning its contents won&apos;t be shown by default anymore.</p>
-<h2 id="_getting_help">Getting help</h2>
-<p>During development, if you don&apos;t remember the name of a target, you can always run <code>make help</code>:</p>

-== Short history
-
-This chapter aims to be a brief record of the life of the
-Erlang.mk project.
-
-=== Before Erlang.mk
-
-Erlang.mk originates from the Cowboy project. Cowboy started
-as a Rebar project and I, Loïc Hoguin, was very happy with it
-for a couple years. Over time however I started getting annoyed
-and frustrated by a number of things, including bad defaults,
-changing defaults and overall slowness.
-
-In particular, at the time I gave up on Rebar, the Cowboy
-test suite was taking about five minutes to run. A quick experiment
-showed I could get much lower times by simply invoking `ct_run`
-directly. On January 4th, 2013, the Cowboy test suite took less
-than a minute to complete.
-
-Following this success I started removing a little more and,
-on the fateful day of January 5th, 2013, removed the dependency
-on Rebar entirely. Rebar, and in particular the concept of
-dependencies, was, and still is, a pretty strong influence.
-
-Erlang.mk was conceived.
-
-A few months passed and, on May 1st, 2013, the Erlang.mk
-repository was created. Erlang.mk was born.
-
-Little did I know how much it would grow.
-
-=== Lifetime of the project
-
-Erlang.mk would eventually become a much larger file able to
-deal with many more projects than just Cowboy. From the birth
-of the project, the biggest force for growth was user contributions,
-because Erlang.mk appealed to a variety of people with different
-needs, needs that Erlang.mk was not fulfilling yet.
-
-The project was split into smaller files focused on a different
-feature each, and a build script was written to build the single
-Erlang.mk file.
-
-A test suite was contributed by a user, and later taken as a basis
-for the current, much more complete test suite. Turns out testing
-a Makefile is pretty straightforward.
-
-A package index was added to solve the problem of discovering
-Erlang projects.
-
-After trying to see if Erlang build tools could cooperate, the
-decision was made to improve compatibility with existing Rebar
-projects by patching Rebar out, using Rebar. This feature, called
-autopatch, proved very successful and made Erlang.mk compatible
-with more than 90% of all Erlang projects.
-
-Erlang.mk documentation was much improved and the Erlang.mk website
-was created in the summer of 2015.
-
-Over the year of 2015, Erlang.mk went from curiosity to a serious
-alternative to other Erlang build tools. The user base increased
-immensely and large projects started using it, including RabbitMQ
-from the 3.6.0 release onward.
-
-A bright future lies ahead.

-[[installation]]
-== Installation
-
-=== On Unix
-
-Erlang.mk requires GNU Make to be installed. While it will
-currently work with GNU Make 3.81, support for this version
-is deprecated and will be removed in 2017. We recommend
-GNU Make 4.1 or later.
-
-Git and Erlang/OTP must also be installed.
-
-Some functionality requires that Autoconf 2.59 or later be
-installed, in order to compile Erlang/OTP. Erlang/OTP may
-have further requirements depending on your needs.
-
-Some packages may require additional libraries.
-
-==== Linux
-
-The commands to install packages vary between distributions:
-
-.Arch Linux
-[source,bash]
-$ pacman -S erlang git make
-
-Alpine Linux and other distributions based on BusyBox come
-with an incompatible `awk` program. Installing the GNU Awk
-(`gawk` on Alpine) solves this issue.
-
-Parallel builds may require the program `flock` that can
-be found in the package `util-linux`.
-
-==== FreeBSD
-
-FreeBSD comes with binary and source packages:
-
-.Install binary packages
-[source,bash]
-$ pkg install erlang git gmake
-
-On FreeBSD the `make` command is BSD Make. Use `gmake` instead.
-
-==== OS X and macOS
-
-While Apple distributes their own GNU Make, their version is
-very old and plagued with numerous bugs. It is recommended
-to install a more recent version from either Homebrew or
-MacPorts:
-
-.Homebrew
-[source,bash]
-$ brew install erlang git make
-
-Homebrew installs GNU Make as `gmake`. The `make` command
-is the one provided by Apple.
-
-.MacPorts
-[source,bash]
-$ sudo port install erlang git gmake
-
-Parallel builds may require the program `flock` which can
-be installed via Homebrew or manually. The instructions
-to install are available from its repository:
-https://github.com/discoteq/flock
-
-=== On Windows
-
-Erlang.mk can be used on Windows inside an MSYS2 environment.
-Cygwin, MSYS (the original) and native Windows (both Batch
-and PowerShell) are currently not supported.
-
-NOTE: Erlang.mk expects Unix line breaks in most of the files
-(LF instead of CRLF). Make sure to configure your text editor
-adequately.
-
-The rest of this section details how to setup Erlang/OTP and
-MSYS2 in order to use Erlang.mk.
-
-==== Installing Erlang/OTP
-
-Erlang.mk requires Erlang/OTP to be installed. The OTP team
-provides binaries of Erlang/OTP for all major and minor releases,
-available from the http://www.erlang.org/download.html[official download page].
-It is recommended that you use the 64-bit installer unless
-technically impossible. Please follow the instructions from
-the installer to complete the installation.
-
-The OTP team also provides a short guide to
-http://www.erlang.org/download.html[installing Erlang/OTP on Windows]
-if you need additional references.
-
-You can install Erlang/OTP silently using the `/S` switch
-on the command line:
-
-----
-C:\Users\essen\Downloads> otp_win64_18.0.exe /S
-----
-
-==== Installing MSYS2
-
-The only supported environment on Windows is MSYS2. MSYS2 is
-a lightweight Unix-like environment for Windows that comes
-with the Arch Linux package manager, `pacman`.
-
-The MSYS2 project provides a http://msys2.github.io[one click installer]
-and instructions to set things up post-installation.
-
-It is currently not possible to use the installer silently.
-Thankfully, the MSYS2 project provides an archive that can
-be used in lieu of the installer. The archive however requires
-_7zip_ to decompress it.
-
-First, download the
-http://sourceforge.net/projects/msys2/files/Base/x86_64/msys2-base-x86_64-20150512.tar.xz/download[MSYS2 base archive]
-and extract it under 'C:\'. Assuming you downloaded the
-archive as 'msys2.tar.xz' and put it in 'C:\', you can
-use the following commands to extract it:
-
-----
-C:\> 7z x msys2.tar.xz
-C:\> 7z x msys2.tar > NUL
-----
-
-Then you can run the two commands needed to perform the
-post-installation setup:
-
-----
-C:\> C:\msys64\usr\bin\bash -lc "pacman --needed --noconfirm -Sy bash pacman pacman-mirrors msys2-runtime"
-C:\> C:\msys64\usr\bin\bash -lc "pacman --noconfirm -Syu"
-----
-
-==== Installing the required MSYS2 packages
-
-After following these instructions, you can install GNU Make,
-Git and any other required softwares. From an MSYS2 shell,
-you can call `pacman` directly:
-
-[source,bash]
-$ pacman -S git make
-
-You can use `pacman -Ss` to search packages. For example,
-to find all packages related to GCC:
-
-[source,bash]
-$ pacman -Ss gcc
-
-If you are going to compile C/C++ code, you will need to
-install this package, as Erlang.mk cannot use the normal
-"gcc" package:
-
-[source,bash]
-$ pacman -S mingw-w64-x86_64-gcc
-
-You can also run commands under the MSYS2 environment from
-the Windows command line or batch files. This command will
-install GNU Make and Git:
-
-----
-C:\> C:\msys64\usr\bin\bash -lc "pacman --noconfirm -S git make"
-----
-
-You can use similar `bash` commands if you need to run programs
-inside the MSYS2 environment from a batch file.
-
-==== Gotchas
-
-While most of the basic functionality will just work, there are
-still some issues. Erlang.mk needs to be fixed to pass the
-right paths when running Erlang scripts. We are working on it.
-Erlang.mk is fully tested on both Linux and Windows, but is
-lacking tests in the areas not yet covered by this guide,
-so expect bugs to be fixed as more tests are added.

-<h2 id="_on_windows">On Windows</h2>
-<p>Erlang.mk can be used on Windows inside an MSYS2 environment. Cygwin, MSYS (the original) and native Windows (both Batch and PowerShell) are currently not supported.</p>
-<p>NOTE: Erlang.mk expects Unix line breaks in most of the files (LF instead of CRLF). Make sure to configure your text editor adequately.</p>
-<p>The rest of this section details how to setup Erlang/OTP and MSYS2 in order to use Erlang.mk.</p>
-<h4 id="_installing_erlang_otp">Installing Erlang/OTP</h4>
-<p>Erlang.mk requires Erlang/OTP to be installed. The OTP team provides binaries of Erlang/OTP for all major and minor releases, available from the <a href="http://www.erlang.org/download.html">official download page</a>. It is recommended that you use the 64-bit installer unless technically impossible. Please follow the instructions from the installer to complete the installation.</p>
-<p>The OTP team also provides a short guide to <a href="http://www.erlang.org/download.html">installing Erlang/OTP on Windows</a> if you need additional references.</p>
-<p>You can install Erlang/OTP silently using the <code>/S</code> switch on the command line:</p>
-<div class="listingblock"><div class="content"><pre>C:\Users\essen\Downloads&gt; otp_win64_18.0.exe /S</pre></div></div>
-<h4 id="_installing_msys2">Installing MSYS2</h4>
-<p>The only supported environment on Windows is MSYS2. MSYS2 is a lightweight Unix-like environment for Windows that comes with the Arch Linux package manager, <code>pacman</code>.</p>
-<p>The MSYS2 project provides a <a href="http://msys2.github.io">one click installer</a> and instructions to set things up post-installation.</p>
-<p>It is currently not possible to use the installer silently. Thankfully, the MSYS2 project provides an archive that can be used in lieu of the installer. The archive however requires <em>7zip</em> to decompress it.</p>
-<p>First, download the <a href="http://sourceforge.net/projects/msys2/files/Base/x86_64/msys2-base-x86_64-20150512.tar.xz/download">MSYS2 base archive</a> and extract it under <em>C:\</em>. Assuming you downloaded the archive as <em>msys2.tar.xz</em> and put it in <em>C:\</em>, you can use the following commands to extract it:</p>
-<div class="listingblock"><div class="content"><pre>C:\&gt; 7z x msys2.tar.xz
-C:\&gt; 7z x msys2.tar &gt; NUL</pre></div></div>
-<p>Then you can run the two commands needed to perform the post-installation setup:</p>
-<div class="listingblock"><div class="content"><pre>C:\&gt; C:\msys64\usr\bin\bash -lc &quot;pacman --needed --noconfirm -Sy bash pacman pacman-mirrors msys2-runtime&quot;
-C:\&gt; C:\msys64\usr\bin\bash -lc &quot;pacman --noconfirm -Syu&quot;</pre></div></div>
-<h4 id="_installing_the_required_msys2_packages">Installing the required MSYS2 packages</h4>
-<p>After following these instructions, you can install GNU Make, Git and any other required softwares. From an MSYS2 shell, you can call <code>pacman</code> directly:</p>

-http://www.lorenzobettini.it
-http://www.gnu.org/software/src-highlite -->
-<pre><tt>$ pacman -S git make</tt></pre>
-</div></div>
-<p>You can use <code>pacman -Ss</code> to search packages. For example, to find all packages related to GCC:</p>
-<div class="listingblock"><div class="content"><!-- Generator: GNU source-highlight 3.1.8
-by Lorenzo Bettini
-http://www.lorenzobettini.it
-http://www.gnu.org/software/src-highlite -->
-<pre><tt>$ pacman -Ss gcc</tt></pre>
-</div></div>
-<p>If you are going to compile C/C++ code, you will need to install this package, as Erlang.mk cannot use the normal &quot;gcc&quot; package:</p>
-<div class="listingblock"><div class="content"><!-- Generator: GNU source-highlight 3.1.8

-<pre><tt>$ pacman -S mingw-w<font color="#993399">64</font>-x86_64-gcc</tt></pre>
-</div></div>
-<p>You can also run commands under the MSYS2 environment from the Windows command line or batch files. This command will install GNU Make and Git:</p>
-<div class="listingblock"><div class="content"><pre>C:\&gt; C:\msys64\usr\bin\bash -lc &quot;pacman --noconfirm -S git make&quot;</pre></div></div>
-<p>You can use similar <code>bash</code> commands if you need to run programs inside the MSYS2 environment from a batch file.</p>
-<h4 id="_gotchas">Gotchas</h4>
-<p>While most of the basic functionality will just work, there are still some issues. Erlang.mk needs to be fixed to pass the right paths when running Erlang scripts. We are working on it. Erlang.mk is fully tested on both Linux and Windows, but is lacking tests in the areas not yet covered by this guide, so expect bugs to be fixed as more tests are added.</p>

-[[kerl]]
-== OTP version management
-
-Erlang.mk comes with integrated support for
-https://github.com/kerl/kerl[Kerl], a shell script that
-automates the downloading, building and installing of
-Erlang/OTP. It can be used to easily build a specific
-Erlang/OTP version (with or without custom build options)
-or maintain different versions side by side.
-
-=== Erlang versions
-
-Erlang.mk uses the Git tags from Erlang/OTP to identify
-OTP versions. The most recent tag at the time of writing
-is `OTP-20.0.4`, which is a patch release of `OTP-20.0`.
-A patch release is a non-official release containing a
-few fixes on top of the official release.
-
-Older versions used a slightly different versioning scheme
-and tag format, for example: `OTP_R16B03`. Beware though,
-there also was an `OTP_R16B03-1` release that fixed a
-critical issue in the initial release.
-
-The README file for all official Erlang/OTP releases can
-be found on http://www.erlang.org/downloads[erlang.org].
-To obtain information about patch releases when they are
-released you need to be subscribed to the
-http://erlang.org/mailman/listinfo/erlang-questions[erlang-questions mailing list].
-
-[[otp_version_pinning]]
-=== OTP version pinning
-
-Erlang.mk can use a specific version of Erlang/OTP when
-interacting with your project. This can be very useful
-when you are working with a team because you can define
-the version you need in the Makefile and Erlang.mk will
-ensure this version is used by everyone in your team.
-
-To pin the version all you need to do is to set the
-`ERLANG_OTP` variable in your Makefile before including
-Erlang.mk. For example, to use `OTP-20.0.4`:
-
-[source,make]
-----
-ERLANG_OTP = OTP-20.0.4
-
-include erlang.mk
-----
-
-The next time you run `make` Erlang.mk will build and
-use the version you configured.
-
-Note that there has been reports that this functionality
-is not compatible with the `.ONESHELL` feature from
-GNU Make.
-
-=== Continuous integration
-
-Erlang.mk can automatically test your project against
-many different Erlang/OTP versions. This functionality
-is documented in the xref:ci[Continuous integration] chapter.
-
-=== Configuring Kerl
-
-All of the Kerl variables can be configured directly in the
-Makefile. All you need to do is to export them. For example,
-to change the installation directory for the Erlang/OTP
-versions managed by Kerl, you could add the following to
-your Makefile:
-
-[source,make]
-export KERL_INSTALL_DIR = $(CURDIR)/erlang
-
-When configuring paths like this, always make sure to provide
-an absolute path in the value. Erlang.mk will NOT expand them
-automatically for you.

-[[limitations]]
-== Limitations
-
-No software is perfect.
-
-It's very important, when evaluating and when using a tool,
-to understand its limitations, so as to avoid making mistakes
-and wasting valuable time.
-
-This chapter lists all known limitations of Erlang.mk.
-
-=== Erlang must be available
-
-Currently Erlang.mk requires you to install Erlang beforehand.
-Installing Erlang is not always easy, particularly if you need
-a specific version of Erlang for a specific project.
-
-In addition, the Erlang being used must be in your `$PATH`
-before you use Erlang.mk.
-
-In the future we envision, Erlang.mk could manage the Erlang
-version you need to use a project. Erlang.mk already does this
-for running tests when using `make ci`, so doing this during
-development is just a step away.
-
-=== Spaces in path
-
-Erlang.mk will currently not work properly if the path to the
-project contains spaces. To check if that is the case, use the
-command `pwd`.
-
-This issue is due to how Makefiles work. There might be ways
-to solve it, we have not given up on it, but it's very low
-priority considering how simple the workaround is.
-
-=== Dependency tracking and modification times
-
-Erlang source files that depend on other files will have their
-modification time updated when they need to be recompiled due
-to a dependency having changed. This could cause some editors to
-think the file changed when it didn't.
-
-Erlang.mk must use this method in order to be able to compile
-files in one `erlc` invocation. The benefits greatly outweigh
-the issue in this case and so there are currently no plans to
-fix this behavior.

-
-<p>No software is perfect.</p>
-<p>It&apos;s very important, when evaluating and when using a tool, to understand its limitations, so as to avoid making mistakes and wasting valuable time.</p>
-<p>This chapter lists all known limitations of Erlang.mk.</p>
-<h2 id="_erlang_must_be_available">Erlang must be available</h2>
-<p>Currently Erlang.mk requires you to install Erlang beforehand. Installing Erlang is not always easy, particularly if you need a specific version of Erlang for a specific project.</p>
-<p>In addition, the Erlang being used must be in your <code>$PATH</code> before you use Erlang.mk.</p>
-<p>In the future we envision, Erlang.mk could manage the Erlang version you need to use a project. Erlang.mk already does this for running tests when using <code>make ci</code>, so doing this during development is just a step away.</p>
-<h2 id="_spaces_in_path">Spaces in path</h2>
-<p>Erlang.mk will currently not work properly if the path to the project contains spaces. To check if that is the case, use the command <code>pwd</code>.</p>
-<p>This issue is due to how Makefiles work. There might be ways to solve it, we have not given up on it, but it&apos;s very low priority considering how simple the workaround is.</p>
-<h2 id="_dependency_tracking_and_modification_times">Dependency tracking and modification times</h2>
-<p>Erlang source files that depend on other files will have their modification time updated when they need to be recompiled due to a dependency having changed. This could cause some editors to think the file changed when it didn&apos;t.</p>
-<p>Erlang.mk must use this method in order to be able to compile files in one <code>erlc</code> invocation. The benefits greatly outweigh the issue in this case and so there are currently no plans to fix this behavior.</p>

-[[overview]]
-== Overview
-
-Now that you know how to get started, let's take a look at
-what Erlang.mk can do for you.
-
-=== Building your project
-
-Erlang.mk is first and foremost a build tool. It is especially
-tailored for Erlang developers and follows widely accepted
-practices in the Erlang community.
-
-Erlang.mk will happily build all xref:building[Erlang-specific files]
-you throw at it. Other kinds of files too, like C or C++ code
-when you are working on xref:ports[a NIF or a port driver].
-
-Erlang.mk embraces the concept of xref:deps[source dependencies].
-It can fetch dependency source code using a variety of mechanisms,
-including fetching from Git, Mercurial or SVN.
-
-Erlang.mk will automatically xref:relx[generate releases]
-when applicable. It can also xref:escript[generate escripts].
-
-=== Exploring the package index
-
-Erlang.mk comes with a xref:deps[built-in package index].
-It is built as an extension of the dependency system and is
-meant to be used for discovery purposes.
-
-No package is ever installed, they are only used as dependencies
-and are always project-specific. They can be thought of as a
-shortcut over plain dependencies.
-
-You can get a list of all packages known to Erlang.mk by using
-the `search` target:
-
-[source,bash]
-$ make search
-
-You can also use this target to search across all packages, for
-example to find all packages related to Cowboy:
-
-[source,bash]
-$ make search q=cowboy
-
-=== Generating documentation
-
-Erlang.mk supports _EDoc_ and _Asciidoc_.
-
-xref:edoc[EDoc] generates HTML documentation directly from
-your source code.
-
-While it is convenient, ask yourself: if all the documentation is
-inside the source code, why not just open the source code directly?
-That's where _Asciidoc_ comes in.
-
-The xref:asciidoc[Asciidoc] plugin expects all documentation
-to be separate from source. It will generate HTML, PDF, man pages and
-more from the documentation you write in the 'doc/src/' folder in
-your repository.
-
-=== Running tests
-
-Erlang.mk supports a lot of different testing and static
-analysis tools.
-
-The xref:shell[make shell] command allows you
-to test your project manually. You can automate these
-unit tests with xref:eunit[EUnit] and test
-your entire system with xref:ct[Common Test].
-xref:coverage[Code coverage] can of course
-be enabled during tests.
-
-Erlang.mk comes with features to make your life easier when
-setting up and using xref:ci[Continuous integration].
-
-On the static analysis side of things, Erlang.mk comes with
-support for xref:dialyzer[Dialyzer] and xref:xref[Xref],
-to perform success typing analysis and cross referencing
-of the code.
-
-=== Need more?
-
-Not convinced yet? You can read about xref:why[why you should use Erlang.mk]
-and its xref:history[history]. And if you're still not
-convinced after that, it's OK! The world would be boring if
-everyone agreed on everything all the time.

-[[ports]]
-== NIFs and port drivers
-
-Erlang.mk can not only build Erlang projects, but also the C code
-that some projects come with, like NIFs and port drivers.
-
-There are two ways to build the C code: using a custom Makefile,
-or making Erlang.mk do it directly. The C code will be built
-as needed when you run `make`.
-
-// @todo something for easier bootstrapping
-
-=== C source code location and Erlang environment
-
-The C source code should be located in the '$(C_SRC_DIR)' directory.
-It defaults to 'c_src/'. Should you need to modify it, all you
-need to do is to set the variable in your Makefile before including
-Erlang.mk:
-
-[source,make]
-C_SRC_DIR = $(CURDIR)/my_nif_source
-
-When this directory exists, Erlang.mk will automatically create a
-file named '$(C_SRC_ENV)'. This file defaults to '$(C_SRC_DIR)/env.mk'.
-This can also be changed:
-
-[source,make]
-C_SRC_ENV = $(C_SRC_DIR)/erlang_env.mk
-
-It contains a few variable definitions for the environment used for the build:
-
-`ERTS_INCLUDE_DIR`::
-	Path to the ERTS include files ('erl_driver.h', 'erl_nif.h' and more).
-`ERL_INTERFACE_INCLUDE_DIR`::
-	Path to the Erl_Interface include files ('ei.h' and related).
-`ERL_INTERFACE_LIB_DIR`::
-	Path to the Erl_Interface static libraries.
-
-=== Using a custom Makefile
-
-Erlang.mk will automatically run `make` if it detects a Makefile
-in '$(C_SRC_DIR)/Makefile'.
-
-The Makefile should have at least two targets: a default target
-(which can be anything, for example `all`) which is invoked when
-building the C code, and a `clean` target invoked when cleaning
-it.
-
-You can include the 'env.mk' file to benefit from the Erlang
-environment detection:
-
-[source,make]
-include env.mk
-
-=== Using Erlang.mk directly
-
-You don't need to write a Makefile to build C source code, however.
-Erlang.mk comes with rules to build both shared libraries and
-executables, using the source files it finds in '$(C_SRC_DIR)'.
-
-By default, Erlang.mk will create a shared library. To change
-this and create an executable instead, put this in your Makefile
-before including Erlang.mk:
-
-[source,make]
-C_SRC_TYPE = executable
-
-The generated file name varies depending on the type of project
-you have (shared library or executable) and on the platform you
-build the project on.
-
-For shared libraries, the generated file name will be
-'$(C_SRC_OUTPUT)$(C_SRC_SHARED_EXTENSION)', with the default
-being '$(CURDIR)/priv/$(PROJECT)' followed by the extension:
-`.dll` on Windows, `.so` everywhere else.
-
-For executables, the generated file name is
-'$(C_SRC_OUTPUT)$(C_SRC_EXECUTABLE_EXTENSION)', with the same
-default except for the extension: `.exe` on Windows, and otherwise
-nothing.
-
-Erlang.mk sets appropriate compile and linker flags by default.
-These flags vary depending on the platform, and can of course
-be overriden.
-
-`CC`::
-	The compiler to be used.
-`CFLAGS`::
-	C compiler flags.
-`CXXFLAGS`::
-	C++ compiler flags.
-`LDFLAGS`::
-	Linker flags.
-`LDLIBS`::
-	Libraries to link against.
-
-The source files are automatically gathered from the contents
-of '$(C_SRC_DIR)'. Erlang.mk looks for '.c', '.C', '.cc' and '.cpp'
-source files. You can define the variable `SOURCES` to manually
-list the files to compile.
-
-=== Propagating compile and linker flags to sub-Makefiles
-
-In some cases it might be necessary to propagate the flags
-you just defined to the sub-Makefiles of your local project.
-You generally can't just export those as this could impact
-the building of dependencies.
-
-Makefiles allow you to export variables for specific targets.
-When doing this, the variables will be exported only when
-this target runs, and not for other targets. It is therefore
-possible to export them when building the C code without
-impacting other build steps.
-
-By adding this to your Makefile all five variables will be
-made available to sub-Makefiles when building C code:
-
-[source,make]
-----
-app-c_src: export CC +=
-app-c_src: export CFLAGS +=
-app-c_src: export CPPFLAGS +=
-app-c_src: export LDFLAGS +=
-app-c_src: export LDLIBS +=
-----
-
-Appending an empty string to the existing value is necessary
-because Makefiles expect an assignment for target-specific
-exports. Alternatively you can set a new value:
-
-[source,make]
-----
-app-c_src: export CFLAGS = -O3

-[[relx]]
-== Releases
-
-Erlang.mk relies on _Relx_ for generating releases. This
-chapter covers the Erlang.mk-specific bits. Consult the
-https://erlware.github.io/relx/[Relx website] for more information.
-
-=== Setup
-
-Erlang.mk will create a release if it detects a Relx configuration
-file in the '$(RELX_CONFIG)' location. This defaults to
-'$(CURDIR)/relx.config'. You can override it by defining
-the variable before including Erlang.mk:
-
-[source,make]
-RELX_CONFIG = $(CURDIR)/webchat.config
-
-It is also possible to have multiple 'relx.config' files.
-For example you might have one for development and one for
-production. You can use conditionals to decide which one
-should be used:
-
-[source,make]
-----
-ifdef PROD
-RELX_CONFIG = $(CURDIR)/relx.prod.config
-else
-RELX_CONFIG = $(CURDIR)/relx.dev.config
-endif
-----
-
-Relx does not need to be installed. Erlang.mk will download
-and build it automatically.
-
-The Relx executable will be saved in the '$(RELX)' file. This
-location defaults to '$(CURDIR)/relx' and can be overriden.
-
-// @todo You can use a custom location by ???
-
-=== Configuration
-
-You can specify additional Relx options using the `RELX_OPTS`
-variable. For example, to enable `dev_mode`:
-
-[source,make]
-RELX_OPTS = -d true
-
-While you can specify the output directory for the release
-in the Relx options directly, Erlang.mk provides a specific
-variable for it: `RELX_OUTPUT_DIR`. It defaults to the '_rel'
-directory. You can also override it:
-
-[source,make]
-RELX_OUTPUT_DIR = /path/to/staging/directory
-
-=== Generating the release
-
-Now that you're all set, all you need to do is generate the
-release. As mentioned before, Erlang.mk will automatically
-generate it when it detects the '$(RELX_CONFIG)' file. This
-means the following command will also build the release:
-
-[source,bash]
-$ make
-
-If you need to generate the release, and only the release,
-the `rel` target can be used:
-
-[source,bash]
-$ make rel
-
-Erlang.mk always generates a tarball alongside the release,
-which can be directly uploaded to a server. The tarball is
-located at `$(RELX_OUTPUT_DIR)/<name>/<name>-<vsn>.tar.gz`.
-
-=== Running the release
-
-Erlang.mk provides a convenience function for running the
-release with one simple command:
-
-[source,bash]
-$ make run
-
-This command will also build the project and generate the
-release if they weren't already. It starts the release in
-_console mode_, meaning you will also have a shell ready to
-use to check things as needed.
-
-=== Upgrading a release
-
-Erlang.mk provides a `relup` target for generating release
-upgrades. Release upgrades allow updating the code and the
-state of a running release without restarting it.
-
-Once your changes are done, you need to update the version
-of the application(s) that will be updated. You also need
-to update the version of the release.
-
-For each application that needs to be updated, an
-http://erlang.org/doc/man/appup.html[appup file]
-must be written. Refer to the Erlang/OTP documentation
-for more details.
-
-For the purpose of this section, assume the initial release
-version was `1`, and the new version is `2`. The name of the
-release will be `example`.
-
-Once all this is done, you can build the tarball for the
-release upgrade:
-
-[source,bash]
-$ make relup
-
-This will create an archive at the root directory of the
-release, `$RELX_OUTPUT_DIR/example/example-2.tar.gz`.
-
-Move the archive to the correct location on the running
-node. From the release's root directory:
-
-[source,bash]
-$ mkdir releases/2/
-$ mv path/to/example-2.tar.gz releases/2/
-
-Finally, upgrade the release:
-
-[source,bash]
-$ bin/example_release upgrade "2/example_release"
-
-Or on Windows:
-
-[source,bash]
-$ bin/example_release.cmd upgrade "2/example_release"
-
-Your release was upgraded!
-
-=== Getting Relx semver value
-
-There is a *workaround* to get the semver value which is
-generated by Relx based on VCS history.
-
-Create a file 'config/version' with only one line inside:
-
-[source,erlang]
-{{ release_version }}
-
-Add/Update the `overlay` section of your `relx.config`:
-
-[source,erlang]
-{overlay, [
-    {template, "config/version", "version"}
-]}.
-
-When you run `make rel` it creates the file '$(RELX_OUTPUT_DIR)/example/version'
-which contains the version value generated by Relx.
-
-[source,bash]
-$ cat _rel/app/release
-1.0.0+build.11.ref5612aa0
-
-In your `Makefile` you can use this simple snippet to get the version,
-but please keep in mind that this should depend on the `rel` target:
-
-[source,make]
-$(shell cat $(RELX_OUTPUT_DIR)/$(RELX_REL_NAME)/version)
-
-For example:
-
-[source,make]
-----
-include erlang.mk
-
-APP_VERSION = $(shell cat $(RELX_OUTPUT_DIR)/$(RELX_REL_NAME)/version)
-myrecipe: all
-        echo APP_VERSION = $(APP_VERSION)
-----
-
-Would output:
-
-[source,bash]
-----
-$ make myrecipe
-...
-===> Starting relx build process ...
-===> Resolving OTP Applications from directories:
-          /home/username/example/apps
-          /home/username/example/deps
-          /usr/lib/erlang/lib
-          /home/username/example/_rel
-===> Resolved example-0.3.10+build.11.ref5612aa0
-===> Including Erts from /usr/lib/erlang
-===> release successfully created!
-===> tarball /home/username/example/_rel/example/example-0.3.10+build.11.ref5612aa0.tar.gz successfully created!
-echo APP_VERSION = 0.3.10+build.11.ref5612aa0
-APP_VERSION = 0.3.10+build.11.ref5612aa0

-[[sfx]]
-== Self-extracting releases
-
-Erlang.mk allows you to package xref:relx[Relx releases] as
-self-extracting archives. These archives contain all the
-files in the release and come in the form of a script that
-will extract and run the release automatically.
-
-This allows you to package the release as a single file
-that can then be executed.
-
-This feature is currently experimental. Feedback is much
-appreciated.
-
-=== Generating the self-extracting archive
-
-To generate a self-extracting release, all you need to do
-is pass the `SFX=1` variable to Make when you build the
-release:
-
-[source,bash]
-$ make SFX=1
-
-This will create a self-extracting archive in
-`$RELX_OUTPUT_DIR/<name>.run`. For example if the release
-is named `hello_world` and `$RELX_OUTPUT_DIR` is the default,
-the file will be located at `_rel/hello_world.run`.
-
-=== Running the release
-
-Simply execute the script to get started:
-
-[source,bash]
-----
-$ ./_rel/hello_world.run
-Exec: /tmp/tmp.3eeEq7E1ta/erts-8.1/bin/erlexec ...
-Root: /tmp/tmp.3eeEq7E1ta
-/tmp/tmp.3eeEq7E1ta
-Erlang/OTP 19 [erts-8.1] [source] [64-bit] [smp:4:4] ...
-
-Eshell V8.1  (abort with ^G)
-(hello_world@localhost)1>
-----
-
-As you can see the archive is extracted to a temporary
-directory before the release can be started.
-
-The self-extracting script currently only supports starting
-the release in `console` mode.

-[[shell]]
-== Erlang shell
-
-Erlang.mk provides a convenient target for starting a shell
-with all the paths set properly to experiment with your code.
-
-=== Configuration
-
-The `SHELL_DEPS` variable can be used to define dependencies
-that are only to be used when the `make shell` command is called.
-For example, if you want to use _kjell_ as your shell:
-
-[source,make]
-SHELL_DEPS = kjell
-
-Dependencies are downloaded and compiled the first time you
-run the `make shell` command.
-
-You can customize the executable used to start the Erlang shell.
-To continue with our example, if you want to use _kjell_ as your
-shell, you also need to change `SHELL_ERL` and point it to the
-`kjell` executable:
-
-[source,make]
-SHELL_ERL = $(DEPS_DIR)/kjell/bin/kjell
-
-You can specify additional options to be used when starting the
-shell using the `SHELL_OPTS` variable:
-
-[source,make]
-SHELL_OPTS = -setcookie chocolate
-
-Any of the usual `erl` options can be used, including `-eval`:
-
-[source,make]
-SHELL_OPTS = -eval 'my_app:run()'
-
-=== Usage
-
-To start the shell, all you need is the following command:
-
-[source,bash]
-$ make shell
-
-The shell can be stopped as usual with a double Ctrl+C or the
-command `q().`.
-
-Note that the `shell` target does not build the application. To do it,
-use either the `app` target or, if you want to include also test
-modules, the `test-build` target.

-<p>Erlang.mk provides a convenient target for starting a shell with all the paths set properly to experiment with your code.</p>
-<h2 id="_configuration">Configuration</h2>
-<p>The <code>SHELL_DEPS</code> variable can be used to define dependencies that are only to be used when the <code>make shell</code> command is called. For example, if you want to use <em>kjell</em> as your shell:</p>

-<pre><tt><font color="#009900">SHELL_DEPS =</font> kjell</tt></pre>
-</div></div>
-<p>Dependencies are downloaded and compiled the first time you run the <code>make shell</code> command.</p>
-<p>You can customize the executable used to start the Erlang shell. To continue with our example, if you want to use <em>kjell</em> as your shell, you also need to change <code>SHELL_ERL</code> and point it to the <code>kjell</code> executable:</p>

-</div></div>
-<p>You can specify additional options to be used when starting the shell using the <code>SHELL_OPTS</code> variable:</p>

-</div></div>
-<h2 id="_usage">Usage</h2>
-<p>To start the shell, all you need is the following command:</p>

-http://www.lorenzobettini.it
-http://www.gnu.org/software/src-highlite -->
-<pre><tt>$ make shell</tt></pre>
-</div></div>
-<p>The shell can be stopped as usual with a double Ctrl+C or the command <code>q().</code>.</p>
-<p>Note that the <code>shell</code> target does not build the application. To do it, use either the <code>app</code> target or, if you want to include also test modules, the <code>test-build</code> target.</p>

-[[sphinx]]
-== Sphinx documentation
-
-Erlang.mk includes targets for running the
-http://www.sphinx-doc.org/[Sphinx documentation generator], which can produce
-documentation in various formats, like HTML, man pages, Texinfo, LaTeX, and
-others.
-
-=== Writing Sphinx documentation
-
-Sphinx generates documentation from a set of
-http://www.sphinx-doc.org/en/stable/rest.html[reST] documents. There is
-a http://www.sphinx-doc.org/en/stable/tutorial.html[quick start guide] on
-Sphinx' website. For Erlang.mk, we'll set up a minimal environment instead.
-
-=== Basic setup
-
-By default, Erlang.mk expects Sphinx documentation to be placed in the 'doc'
-directory, with 'doc/conf.py' config file in particular. The file contains
-information about the project, among the other things.
-
-A minimal 'doc/conf.py' will look similar to this:
-
-[source,python]
-----
-project = 'My Project'
-version = '0.0'
-release = '0.0.1'
-master_doc = 'index'
-source_suffix = '.rst'
-----
-
-It points to a 'doc/index.rst' document. A simple skeleton includes a table of
-contents for all documentation, and links to generated index of terms and
-a search page:
-
-----
-My Project
-==========
-
-Contents:
-
-.. toctree::
-   :maxdepth: 2
-
-   other_page
-
-Indices and tables
-==================
-
-* :ref:`genindex`
-* :ref:`search`
-----
-
-The skeleton above has a link to one other page, 'doc/other_page.rst'. Simple
-header with some text will do for now:
-
-----
-Other Page
-==========
-
-Lorem ipsum dolor sit amet...
-----
-
-The files above are enough to build HTML documentation to the 'html' directory.
-
-[source,bash]
-$ make docs     # all the docs, including EDoc and AsciiDoc if applicable
-$ make sphinx   # Sphinx docs specifically
-
-=== Erlang.mk configuration
-
-Erlang.mk defaults to the following configuration:
-
-[source,make]
-SPHINX_FORMATS = html
-SPHINX_SOURCE = doc
-
-To change the location of Sphinx sources, you need to set the `$(SPHINX_SOURCE)`
-variable. The 'conf.py' file should also be placed in that directory, unless you
-specify `$(SPHINX_CONFDIR)`.
-
-The variable `$(SPHINX_OPTS)` allows to provide options to `sphinx-build`, which
-is particularly useful for `-D name=value` options. You can even forego
-'doc/conf.py' file, using `-D name=value` in combination with the `-C` option,
-though in this case you will need to manually call `make sphinx` or add the
-`sphinx` target to dependencies of `docs`.
-
-The `$(SPHINX_FORMATS)` variable lists formats to generate. By default only HTML
-is generated, but it can also build man pages or LaTeX documents which can later
-be converted to PDF. See the
-http://www.sphinx-doc.org/en/stable/invocation.html#cmdoption-sphinx-build-b[description of the `-b` option]
-for `sphinx-build` for a list of known formats.
-
-Formats are by default generated to a directory called after the format
-('html' for HTML, 'man' for man pages, and so on). To change this behaviour
-for a specific format, you can set the `$(sphinx_$(format)_output)` variable, e.g.
-`$(sphinx_html_output)` for 'html' or `$(sphinx_man_output)` for 'man'.
-There are also `$(sphinx_$(format)_opts)` variables for setting `sphinx-build`
-options for a single format only.
-
-=== Generating man pages
-
-To generate man pages, you need to include `man` in `$(SPHINX_FORMATS)` in
-your Makefile and define the `man_pages` option in 'doc/conf.py':
-
-[source,python]
-----
-man_pages = [
-    ('doc_name', 'page_name', 'Manpage Title', ['Page Author'], 1),
-]
-----
-
-As the
-http://www.sphinx-doc.org/en/stable/config.html#options-for-manual-page-output[Sphinx documentation]
-indicates, the structure is:
-
-* `doc_name` is the path to the man page's source (relative `$(SPHINX_SOURCE)`),
-  without the '.rst' suffix
-* `page_name` is the name of the resulting man page, which will be used as a base
-  for the output file name and will be included in the generated man page
-* `Manpage Title` is a short, one-line description, which will be included in
-  the generated man page on a position that's used by the `apropos` command
-* `Page Author` (or more of them) will be included in the autogenerated `AUTHOR`
-  section. Leaving this field empty disables generating the `AUTHOR` section
-* `1` is the man page section number
-
-With the above configuration (and Erlang.mk's defaults), 'doc/doc_name.rst' will
-be used to generate 'man/page_name.1'.

-== Updating Erlang.mk
-
-This chapter describes how to update the 'erlang.mk' file
-in your repository.
-
-=== Initial bootstrap
-
-The first time you use Erlang.mk, it will bootstrap itself.
-It always uses the most recent version for this, so you don't
-have to update after creating your project.
-
-=== Updating
-
-Later on though, updating becomes a necessity. Erlang.mk
-developers and contributors relentlessly improve the project
-and add new features; it would be a waste not to benefit
-from this.
-
-That's why updating Erlang.mk is so simple. All you need
-to do is to call `make erlang-mk`:
-
-[source,bash]
-----
-$ make erlang-mk
-git clone https://github.com/ninenines/erlang.mk .erlang.mk.build
-Cloning into '.erlang.mk.build'...
-remote: Counting objects: 4035, done.
-remote: Compressing objects: 100% (12/12), done.
-remote: Total 4035 (delta 8), reused 4 (delta 4), pack-reused 4019
-Receiving objects: 100% (4035/4035), 1.10 MiB | 1000.00 KiB/s, done.
-Resolving deltas: 100% (2442/2442), done.
-Checking connectivity... done.
-if [ -f build.config ]; then cp build.config .erlang.mk.build; fi
-cd .erlang.mk.build && make
-make[1]: Entering directory '/home/essen/tmp/emkg/hello_joe/.erlang.mk.build'
-awk 'FNR==1 && NR!=1{print ""}1' core/core.mk index/*.mk core/index.mk core/deps.mk plugins/protobuffs.mk core/erlc.mk core/docs.mk core/test.mk plugins/asciidoc.mk plugins/bootstrap.mk plugins/c_src.mk plugins/ci.mk plugins/ct.mk plugins/dialyzer.mk plugins/edoc.mk plugins/elvis.mk plugins/erlydtl.mk plugins/escript.mk plugins/eunit.mk plugins/relx.mk plugins/shell.mk plugins/triq.mk plugins/xref.mk plugins/cover.mk \
-	| sed 's/^ERLANG_MK_VERSION = .*/ERLANG_MK_VERSION = 1.2.0-642-gccd2b9f/' > erlang.mk
-make[1]: Leaving directory '/home/essen/tmp/emkg/hello_joe/.erlang.mk.build'
-cp .erlang.mk.build/erlang.mk ./erlang.mk
-rm -rf .erlang.mk.build
-----
-
-All that's left to do is to commit the file!
-
-Yep, it's that easy.
-
-=== Customizing the build
-
-Erlang.mk allows you to customize which components are to be included
-in the 'erlang.mk' file. The `WITHOUT` variable allows you to
-remove components from the default Erlang.mk build. The 'build.config'
-file lets you define exactly what goes in (including your own code!),
-and in what order.
-
-The `WITHOUT` file contains the list of components to exclude from
-the build. For example, to exclude the package index and the EDoc
-plugin when bootstrapping your application:
-
-[source,bash]
-$ make -f erlang.mk bootstrap WITHOUT="index plugins/edoc"
-
-The generated Erlang.mk will never include those components when
-you update it, until you change your mind and use the `WITHOUT`
-variable again when you upgrade:
-
-[source,bash]
-$ make erlang-mk WITHOUT=index
-
-The 'build.config' file is automatically used when you bootstrap
-Erlang.mk or when you update it with `make erlang-mk`.
-
-The 'build.config' file contains the list of all files that will
-be built into the resulting 'erlang.mk' file. You can start from
-the https://github.com/ninenines/erlang.mk/blob/master/build.config[most recent version]
-and customize to your needs.
-
-You can also name the file differently or put it in a separate folder
-by modifying the value for `ERLANG_MK_BUILD_CONFIG`. You can also
-tell Erlang.mk to use a different temporary directory by changing
-the `ERLANG_MK_BUILD_DIR` variable.
-
-If you want to use a different repository or a specific commit for
-updating, you may use the variables `ERLANG_MK_REPO` and
-`ERLANG_MK_COMMIT`.

-<h2 id="_customizing_the_build">Customizing the build</h2>
-<p>Erlang.mk allows you to customize which components are to be included in the <em>erlang.mk</em> file. The <code>WITHOUT</code> variable allows you to remove components from the default Erlang.mk build. The <em>build.config</em> file lets you define exactly what goes in (including your own code!), and in what order.</p>
-<p>The <code>WITHOUT</code> file contains the list of components to exclude from the build. For example, to exclude the package index and the EDoc plugin when bootstrapping your application:</p>

-</div></div>
-<p>The generated Erlang.mk will never include those components when you update it, until you change your mind and use the <code>WITHOUT</code> variable again when you upgrade:</p>

-</div></div>
-<p>The <em>build.config</em> file is automatically used when you bootstrap Erlang.mk or when you update it with <code>make erlang-mk</code>.</p>
-<p>The <em>build.config</em> file contains the list of all files that will be built into the resulting <em>erlang.mk</em> file. You can start from the <a href="https://github.com/ninenines/erlang.mk/blob/master/build.config">most recent version</a> and customize to your needs.</p>
-<p>You can also name the file differently or put it in a separate folder by modifying the value for <code>ERLANG_MK_BUILD_CONFIG</code>. You can also tell Erlang.mk to use a different temporary directory by changing the <code>ERLANG_MK_BUILD_DIR</code> variable.</p>
-<p>If you want to use a different repository or a specific commit for updating, you may use the variables <code>ERLANG_MK_REPO</code> and <code>ERLANG_MK_COMMIT</code>.</p>

-[[why]]
-== Why Erlang.mk
-
-Why would you choose Erlang.mk, if not for its
-xref:overview[many features]? This chapter will
-attempt to answer that.
-
-=== Erlang.mk is fast
-
-Erlang.mk is as fast as it gets.
-
-Erlang.mk will group the compilation of files so as to avoid
-running the BEAM more than necessary. This saves many seconds
-compared to traditional Makefiles, even on small projects.
-
-Erlang.mk will not try to be too smart. It provides a simple
-solution that works for most people, and gives additional
-options for projects that run into edge cases, often in the
-form of extra variables or rules to be defined.
-
-=== Erlang.mk gives you the full power of Unix
-
-Erlang.mk is a Makefile.
-
-You could use Erlang.mk directly without configuring anything
-and it would just work. But you can also extend it greatly
-either through configuration or hooks, and you can of course
-add your own rules to the Makefile.
-
-In all cases: for configuration, hooks or custom rules, you
-have all the power of Unix at your disposal, and can call
-any utility _or even any language interpreter_ you want,
-every time you need to. Erlang.mk also allows you to write
-scripts in this small language called Erlang directly inside
-your Makefile if you ever need to...
-
-=== Erlang.mk is a text file
-
-Erlang.mk is a Makefile.
-
-Which means Erlang.mk is a simple text file. You can edit a
-text file. Nothing stops you. If you run into any bug, or
-behavior that does not suit you, you can just open the
-'erlang.mk' file in your favorite editor, fix and/or comment
-a few lines, save, and try again. It's as simple as it gets.
-
-Currently using a binary build tool? Good luck with that.
-
-=== Erlang.mk can manage Erlang itself
-
-Erlang.mk isn't written in Erlang.
-
-That's not a good thing, you say? Well, here's one thing
-that Erlang.mk and Makefiles can do for you that Erlang
-build tool can't easily: choose what version of Erlang is
-to be used for compiling the project.
-
-This really is a one-liner in Erlang.mk (a few more lines
-if you also let it download and build Erlang directly)
-and allows for even greater things, like testing your
-project across all supported Erlang versions in one small
-command: `make -k ci`.
-
-=== Erlang.mk can do more than Erlang
-
-Erlang.mk doesn't care what your dependencies are written in.
-
-Erlang.mk will happily compile any dependency, as long as
-they come with a Makefile. The dependency can be written
-in C, C++ or even Javascript... Who cares, really? If you
-need Erlang.mk to fetch it, then Erlang.mk will fetch it
-and compile it as needed.
-
-=== Erlang.mk integrates nicely in Make and Automake projects
-
-If you are planning to put your project in the middle of
-a Make or Automake-based build environment, then the most
-logical thing to do is to use a Makefile.
-
-Erlang.mk will happily sit in such an environment and behave
-as you expect it to.

-== Embedded mode
-
-Embedded mode allows you to insert Ranch listeners directly
-in your supervision tree. This allows for greater fault tolerance
-control by permitting the shutdown of a listener due to the
-failure of another part of the application and vice versa.
-
-=== Embedding
-
-To embed Ranch in your application you can simply add the child specs
-to your supervision tree. This can all be done in the `init/1` function
-of one of your application supervisors.
-
-Ranch requires at the minimum two kinds of child specs for embedding.
-First, you need to add `ranch_sup` to your supervision tree, only once,
-regardless of the number of listeners you will use. Then you need to
-add the child specs for each listener.
-
-Ranch has a convenience function for getting the listeners child specs
-called `ranch:child_spec/6`, that works like `ranch:start_listener/6`,
-except that it doesn't start anything, it only returns child specs.
-
-As for `ranch_sup`, the child spec is simple enough to not require a
-convenience function.
-
-The following example adds both `ranch_sup` and one listener to another
-application's supervision tree.
-
-.Embed Ranch directly in your supervision tree
-
-[source,erlang]
-----
-init([]) ->
-	RanchSupSpec = {ranch_sup, {ranch_sup, start_link, []},
-		permanent, 5000, supervisor, [ranch_sup]},
-	ListenerSpec = ranch:child_spec(echo, 100,
-		ranch_tcp, [{port, 5555}],
-		echo_protocol, []
-	),
-	{ok, {{one_for_one, 10, 10}, [RanchSupSpec, ListenerSpec]}}.
-----
-
-Remember, you can add as many listener child specs as needed, but only
-one `ranch_sup` spec!
-
-It is recommended that your architecture makes sure that all listeners
-are restarted if `ranch_sup` fails. See the Ranch internals chapter for
-more details on how Ranch does it.

-== Listeners
-
-A listener is a set of processes whose role is to listen on a port
-for new connections. It manages a pool of acceptor processes, each
-of them indefinitely accepting connections. When it does, it starts
-a new process executing the protocol handler code. All the socket
-programming is abstracted through the user of transport handlers.
-
-The listener takes care of supervising all the acceptor and connection
-processes, allowing developers to focus on building their application.
-
-=== Starting a listener
-
-Ranch does nothing by default. It is up to the application developer
-to request that Ranch listens for connections.
-
-A listener can be started and stopped at will.
-
-When starting a listener, a number of different settings are required:
-
-* A name to identify it locally and be able to interact with it.
-* The number of acceptors in the pool.
-* A transport handler and its associated options.
-* A protocol handler and its associated options.
-
-Ranch includes both TCP and SSL transport handlers, respectively
-`ranch_tcp` and `ranch_ssl`.
-
-A listener can be started by calling the `ranch:start_listener/6`
-function. Before doing so however, you must ensure that the `ranch`
-application is started.
-
-.Starting the Ranch application
-
-[source,erlang]
-ok = application:start(ranch).
-
-You are then ready to start a listener. Let's call it `tcp_echo`. It will
-have a pool of 100 acceptors, use a TCP transport and forward connections
-to the `echo_protocol` handler.
-
-.Starting a listener for TCP connections on port 5555
-
-[source,erlang]
-{ok, _} = ranch:start_listener(tcp_echo, 100,
-	ranch_tcp, [{port, 5555}],
-	echo_protocol, []
-).
-
-You can try this out by compiling and running the `tcp_echo` example in the
-examples directory. To do so, open a shell in the 'examples/tcp_echo/'
-directory and run the following command:
-
-.Building and starting a Ranch example
-
-[source,bash]
-$ make run
-
-You can then connect to it using telnet and see the echo server reply
-everything you send to it. Then when you're done testing, you can use
-the `Ctrl+]` key to escape to the telnet command line and type
-`quit` to exit.
-
-.Connecting to the example listener with telnet
-
-[source,bash]
-----
-$ telnet localhost 5555
-Trying 127.0.0.1...
-Connected to localhost.
-Escape character is '^]'.
-Hello!
-Hello!
-It works!
-It works!
-^]
-
-telnet> quit
-Connection closed.
-----
-
-=== Stopping a listener
-
-All you need to stop a Ranch listener is to call the
-`ranch:stop_listener/1` function with the listener's name
-as argument. In the previous section we started the listener
-named `tcp_echo`. We can now stop it.
-
-.Stopping a listener
-
-[source,erlang]
-ranch:stop_listener(tcp_echo).
-
-=== Default transport options
-
-By default the socket will be set to return `binary` data, with the
-options `{active, false}`, `{packet, raw}`, `{reuseaddr, true}` set.
-These values can't be overriden when starting the listener, but
-they can be overriden using `Transport:setopts/2` in the protocol.
-
-It will also set `{backlog, 1024}` and `{nodelay, true}`, which
-can be overriden at listener startup.
-
-=== Listening on a random port
-
-You do not have to specify a specific port to listen on. If you give
-the port number 0, or if you omit the port number entirely, Ranch will
-start listening on a random port.
-
-You can retrieve this port number by calling `ranch:get_port/1`. The
-argument is the name of the listener you gave in `ranch:start_listener/6`.
-
-.Starting a listener for TCP connections on a random port
-
-[source,erlang]
-{ok, _} = ranch:start_listener(tcp_echo, 100,
-	ranch_tcp, [{port, 0}],
-	echo_protocol, []
-).
-Port = ranch:get_port(tcp_echo).
-
-=== Listening on privileged ports
-
-Some systems limit access to ports below 1024 for security reasons.
-This can easily be identified by an `{error, eacces}` error when trying
-to open a listening socket on such a port.
-
-The methods for listening on privileged ports vary between systems,
-please refer to your system's documentation for more information.
-
-We recommend the use of port rewriting for systems with a single server,
-and load balancing for systems with multiple servers. Documenting these
-solutions is however out of the scope of this guide.
-
-=== Accepting connections on an existing socket
-
-If you want to accept connections on an existing socket, you can use the
-`socket` transport option, which should just be the relevant data returned
-from the connect function for the transport or the underlying socket library
-(`gen_tcp:connect`, `ssl:connect`). The accept function will then be
-called on the passed in socket. You should connect the socket in
-`{active, false}` mode, as well.
-
-Note, however, that because of a bug in SSL, you cannot change ownership of an
-SSL listen socket prior to R16. Ranch will catch the error thrown, but the
-owner of the SSL socket will remain as whatever process created the socket.
-However, this will not affect accept behaviour unless the owner process dies,
-in which case the socket is closed. Therefore, to use this feature with SSL
-with an erlang release prior to R16, ensure that the SSL socket is opened in a
-persistant process.
-
-=== Limiting the number of concurrent connections
-
-The `max_connections` transport option allows you to limit the number
-of concurrent connections. It defaults to 1024. Its purpose is to
-prevent your system from being overloaded and ensuring all the
-connections are handled optimally.
-
-.Customizing the maximum number of concurrent connections
-
-[source,erlang]
-{ok, _} = ranch:start_listener(tcp_echo, 100,
-	ranch_tcp, [{port, 5555}, {max_connections, 100}],
-	echo_protocol, []
-).
-
-You can disable this limit by setting its value to the atom `infinity`.
-
-.Disabling the limit for the number of connections
-
-[source,erlang]
-{ok, _} = ranch:start_listener(tcp_echo, 100,
-	ranch_tcp, [{port, 5555}, {max_connections, infinity}],
-	echo_protocol, []
-).
-
-You may not always want connections to be counted when checking for
-`max_connections`. For example you might have a protocol where both
-short-lived and long-lived connections are possible. If the long-lived
-connections are mostly waiting for messages, then they don't consume
-much resources and can safely be removed from the count.
-
-To remove the connection from the count, you must call the
-`ranch:remove_connection/1` from within the connection process,
-with the name of the listener as the only argument.
-
-.Removing a connection from the count of connections
-
-[source,erlang]
-ranch:remove_connection(Ref).
-
-As seen in the chapter covering protocols, this pid is received as the
-first argument of the protocol's `start_link/4` callback.
-
-You can modify the `max_connections` value on a running listener by
-using the `ranch:set_max_connections/2` function, with the name of the
-listener as first argument and the new value as the second.
-
-.Upgrading the maximum number of connections
-
-[source,erlang]
-ranch:set_max_connections(tcp_echo, MaxConns).
-
-The change will occur immediately.
-
-=== Using a supervisor for connection processes
-
-Ranch allows you to define the type of process that will be used
-for the connection processes. By default it expects a `worker`.
-When the `connection_type` configuration value is set to `supervisor`,
-Ranch will consider that the connection process it manages is a
-supervisor and will reflect that in its supervision tree.
-
-Connection processes of type `supervisor` can either handle the
-socket directly or through one of their children. In the latter
-case the start function for the connection process must return
-two pids: the pid of the supervisor you created (that will be
-supervised) and the pid of the protocol handling process (that
-will receive the socket).
-
-Instead of returning `{ok, ConnPid}`, simply return
-`{ok, SupPid, ConnPid}`.
-
-It is very important that the connection process be created
-under the supervisor process so that everything works as intended.
-If not, you will most likely experience issues when the supervised
-process is stopped.
-
-=== Upgrading
-
-Ranch allows you to upgrade the protocol options. This takes effect
-immediately and for all subsequent connections.
-
-To upgrade the protocol options, call `ranch:set_protocol_options/2`
-with the name of the listener as first argument and the new options
-as the second.
-
-.Upgrading the protocol options
-
-[source,erlang]
-ranch:set_protocol_options(tcp_echo, NewOpts).
-
-All future connections will use the new options.
-
-You can also retrieve the current options similarly by
-calling `ranch:get_protocol_options/1`.
-
-.Retrieving the current protocol options
-
-[source,erlang]
-Opts = ranch:get_protocol_options(tcp_echo).

-<h2 id="_listening_on_privileged_ports">Listening on privileged ports</h2>
-<p>Some systems limit access to ports below 1024 for security reasons. This can easily be identified by an <code>{error, eacces}</code> error when trying to open a listening socket on such a port.</p>
-<p>The methods for listening on privileged ports vary between systems, please refer to your system&apos;s documentation for more information.</p>
-<p>We recommend the use of port rewriting for systems with a single server, and load balancing for systems with multiple servers. Documenting these solutions is however out of the scope of this guide.</p>
-<h2 id="_accepting_connections_on_an_existing_socket">Accepting connections on an existing socket</h2>
-<p>If you want to accept connections on an existing socket, you can use the <code>socket</code> transport option, which should just be the relevant data returned from the connect function for the transport or the underlying socket library (<code>gen_tcp:connect</code>, <code>ssl:connect</code>). The accept function will then be called on the passed in socket. You should connect the socket in <code>{active, false}</code> mode, as well.</p>
-<p>Note, however, that because of a bug in SSL, you cannot change ownership of an SSL listen socket prior to R16. Ranch will catch the error thrown, but the owner of the SSL socket will remain as whatever process created the socket. However, this will not affect accept behaviour unless the owner process dies, in which case the socket is closed. Therefore, to use this feature with SSL with an erlang release prior to R16, ensure that the SSL socket is opened in a persistant process.</p>
-<h2 id="_limiting_the_number_of_concurrent_connections">Limiting the number of concurrent connections</h2>
-<p>The <code>max_connections</code> transport option allows you to limit the number of concurrent connections. It defaults to 1024. Its purpose is to prevent your system from being overloaded and ensuring all the connections are handled optimally.</p>

-<h2 id="_using_a_supervisor_for_connection_processes">Using a supervisor for connection processes</h2>
-<p>Ranch allows you to define the type of process that will be used for the connection processes. By default it expects a <code>worker</code>. When the <code>connection_type</code> configuration value is set to <code>supervisor</code>, Ranch will consider that the connection process it manages is a supervisor and will reflect that in its supervision tree.</p>
-<p>Connection processes of type <code>supervisor</code> can either handle the socket directly or through one of their children. In the latter case the start function for the connection process must return two pids: the pid of the supervisor you created (that will be supervised) and the pid of the protocol handling process (that will receive the socket).</p>
-<p>Instead of returning <code>{ok, ConnPid}</code>, simply return <code>{ok, SupPid, ConnPid}</code>.</p>
-<p>It is very important that the connection process be created under the supervisor process so that everything works as intended. If not, you will most likely experience issues when the supervised process is stopped.</p>
-<h2 id="_upgrading">Upgrading</h2>
-<p>Ranch allows you to upgrade the protocol options. This takes effect immediately and for all subsequent connections.</p>
-<p>To upgrade the protocol options, call <code>ranch:set_protocol_options/2</code> with the name of the listener as first argument and the new options as the second.</p>

-== Writing parsers
-
-There are three kinds of protocols:
-
-* Text protocols
-* Schema-less binary protocols
-* Schema-based binary protocols
-
-This chapter introduces the first two kinds. It will not cover
-more advanced topics such as continuations or parser generators.
-
-This chapter isn't specifically about Ranch, we assume here that
-you know how to read data from the socket. The data you read and
-the data that hasn't been parsed is saved in a buffer. Every
-time you read from the socket, the data read is appended to the
-buffer. What happens next depends on the kind of protocol. We
-will only cover the first two.
-
-=== Parsing text
-
-Text protocols are generally line based. This means that we can't
-do anything with them until we receive the full line.
-
-A simple way to get a full line is to use `binary:split/{2,3}`.
-
-.Using binary:split/2 to get a line of input
-
-[source,erlang]
-case binary:split(Buffer, <<"\n">>) of
-	[_] ->
-		get_more_data(Buffer);
-	[Line, Rest] ->
-		handle_line(Line, Rest)
-end.
-
-In the above example, we can have two results. Either there was
-a line break in the buffer and we get it split into two parts,
-the line and the rest of the buffer; or there was no line break
-in the buffer and we need to get more data from the socket.
-
-Next, we need to parse the line. The simplest way is to again
-split, here on space. The difference is that we want to split
-on all spaces character, as we want to tokenize the whole string.
-
-.Using binary:split/3 to split text
-
-[source,erlang]
-case binary:split(Line, <<" ">>, [global]) of
-	[<<"HELLO">>] ->
-		be_polite();
-	[<<"AUTH">>, User, Password] ->
-		authenticate_user(User, Password);
-	[<<"QUIT">>, Reason] ->
-		quit(Reason)
-	%% ...
-end.
-
-Pretty simple, right? Match on the command name, get the rest
-of the tokens in variables and call the respective functions.
-
-After doing this, you will want to check if there is another
-line in the buffer, and handle it immediately if any.
-Otherwise wait for more data.
-
-=== Parsing binary
-
-Binary protocols can be more varied, although most of them are
-pretty similar. The first four bytes of a frame tend to be
-the size of the frame, which is followed by a certain number
-of bytes for the type of frame and then various parameters.
-
-Sometimes the size of the frame includes the first four bytes,
-sometimes not. Other times this size is encoded over two bytes.
-And even other times little-endian is used instead of big-endian.
-
-The general idea stays the same though.
-
-.Using binary pattern matching to split frames
-
-[source,erlang]
-<< Size:32, _/bits >> = Buffer,
-case Buffer of
-	<< Frame:Size/binary, Rest/bits >> ->
-		handle_frame(Frame, Rest);
-	_ ->
-		get_more_data(Buffer)
-end.
-
-You will then need to parse this frame using binary pattern
-matching, and handle it. Then you will want to check if there
-is another frame fully received in the buffer, and handle it
-immediately if any. Otherwise wait for more data.

-== Protocols
-
-A protocol handler starts a connection process and defines the
-protocol logic executed in this process.
-
-=== Writing a protocol handler
-
-All protocol handlers must implement the `ranch_protocol` behavior
-which defines a single callback, `start_link/4`. This callback is
-responsible for spawning a new process for handling the connection.
-It receives four arguments: the name of the listener, the socket, the
-transport handler being used and the protocol options defined in
-the call to `ranch:start_listener/6`. This callback must
-return `{ok, Pid}`, with `Pid` the pid of the new process.
-
-The newly started process can then freely initialize itself. However,
-it must call `ranch:accept_ack/1` before doing any socket operation.
-This will ensure the connection process is the owner of the socket.
-It expects the listener's name as argument.
-
-.Acknowledge accepting the socket
-
-[source,erlang]
-ok = ranch:accept_ack(Ref).
-
-If your protocol code requires specific socket options, you should
-set them while initializing your connection process, after
-calling `ranch:accept_ack/1`. You can use `Transport:setopts/2`
-for that purpose.
-
-Following is the complete protocol code for the example found
-in `examples/tcp_echo/`.
-
-.Protocol module that echoes everything it receives
-
-[source,erlang]
-----
--module(echo_protocol).
--behaviour(ranch_protocol).
-
--export([start_link/4]).
--export([init/4]).
-
-start_link(Ref, Socket, Transport, Opts) ->
-	Pid = spawn_link(?MODULE, init, [Ref, Socket, Transport, Opts]),
-	{ok, Pid}.
-
-init(Ref, Socket, Transport, _Opts = []) ->
-	ok = ranch:accept_ack(Ref),
-	loop(Socket, Transport).
-
-loop(Socket, Transport) ->
-	case Transport:recv(Socket, 0, 5000) of
-		{ok, Data} ->
-			Transport:send(Socket, Data),
-			loop(Socket, Transport);
-		_ ->
-			ok = Transport:close(Socket)
-	end.
-----
-
-=== Using gen_server
-
-Special processes like the ones that use the `gen_server` or `gen_fsm`
-behaviours have the particularity of having their `start_link` call not
-return until the `init` function returns. This is problematic, because
-you won't be able to call `ranch:accept_ack/1` from the `init` callback
-as this would cause a deadlock to happen.
-
-There are two ways of solving this problem.
-
-The first, and probably the most elegant one, is to make use of the
-`gen_server:enter_loop/3` function. It allows you to start your process
-normally (although it must be started with `proc_lib` like all special
-processes), then perform any needed operations before falling back into
-the normal `gen_server` execution loop.
-
-.Use a gen_server for protocol handling
-
-[source,erlang]
-----
--module(my_protocol).
--behaviour(gen_server).
--behaviour(ranch_protocol).
-
--export([start_link/4]).
--export([init/4]).
-%% Exports of other gen_server callbacks here.
-
-start_link(Ref, Socket, Transport, Opts) ->
-	proc_lib:start_link(?MODULE, init, [Ref, Socket, Transport, Opts]).
-
-init(Ref, Socket, Transport, _Opts = []) ->
-	ok = proc_lib:init_ack({ok, self()}),
-	%% Perform any required state initialization here.
-	ok = ranch:accept_ack(Ref),
-	ok = Transport:setopts(Socket, [{active, once}]),
-	gen_server:enter_loop(?MODULE, [], {state, Socket, Transport}).
-
-%% Other gen_server callbacks here.
-----
-
-The second method involves triggering a timeout just after `gen_server:init`
-ends. If you return a timeout value of `0` then the `gen_server` will call
-`handle_info(timeout, _, _)` right away.
-
-.Use a gen_server for protocol handling, method 2

-<p>A protocol handler starts a connection process and defines the protocol logic executed in this process.</p>
-<h2 id="_writing_a_protocol_handler">Writing a protocol handler</h2>
-<p>All protocol handlers must implement the <code>ranch_protocol</code> behavior which defines a single callback, <code>start_link/4</code>. This callback is responsible for spawning a new process for handling the connection. It receives four arguments: the name of the listener, the socket, the transport handler being used and the protocol options defined in the call to <code>ranch:start_listener/6</code>. This callback must return <code>{ok, Pid}</code>, with <code>Pid</code> the pid of the new process.</p>
-<p>The newly started process can then freely initialize itself. However, it must call <code>ranch:accept_ack/1</code> before doing any socket operation. This will ensure the connection process is the owner of the socket. It expects the listener&apos;s name as argument.</p>

-<h2 id="_using_gen_server">Using gen_server</h2>
-<p>Special processes like the ones that use the <code>gen_server</code> or <code>gen_fsm</code> behaviours have the particularity of having their <code>start_link</code> call not return until the <code>init</code> function returns. This is problematic, because you won&apos;t be able to call <code>ranch:accept_ack/1</code> from the <code>init</code> callback as this would cause a deadlock to happen.</p>
-<p>There are two ways of solving this problem.</p>
-<p>The first, and probably the most elegant one, is to make use of the <code>gen_server:enter_loop/3</code> function. It allows you to start your process normally (although it must be started with <code>proc_lib</code> like all special processes), then perform any needed operations before falling back into the normal <code>gen_server</code> execution loop.</p>

-== SSL client authentication
-
-=== Purpose
-
-SSL client authentication is a mechanism allowing applications to
-identify certificates. This allows your application to make sure that
-the client is an authorized certificate, but makes no claim about
-whether the user can be trusted. This can be combined with a password
-based authentication to attain greater security.
-
-The server only needs to retain the certificate serial number and
-the certificate issuer to authenticate the certificate. Together,
-they can be used to uniquely identify a certicate.
-
-As Ranch allows the same protocol code to be used for both SSL and
-non-SSL transports, you need to make sure you are in an SSL context
-before attempting to perform an SSL client authentication. This
-can be done by checking the return value of `Transport:name/0`.
-
-=== Obtaining client certificates
-
-You can obtain client certificates from various sources. You can
-generate them yourself, or you can use a service like CAcert.org
-which allows you to generate client and server certificates for
-free.
-
-Following are the steps you need to take to create a CAcert.org
-account, generate a certificate and install it in your favorite
-browser.
-
-* Open [CAcert.org](http://cacert.org) in your favorite browser
-* Root Certificate link: install both certificates
-* Join (Register an account)
-* Verify your account (check your email inbox!)
-* Log in
-* Client Certificates: New
-* Follow instructions to create the certificate
-* Install the certificate in your browser
-
-You can optionally save the certificate for later use, for example
-to extract the `IssuerID` information as will be detailed later on.
-
-=== Transport configuration
-
-The SSL transport does not request a client certificate by default.
-You need to specify the `{verify, verify_peer}` option when starting
-the listener to enable this behavior.
-
-.Configure a listener for SSL authentication
-
-[source,erlang]
-{ok, _} = ranch:start_listener(my_ssl, 100,
-	ranch_ssl, [
-		{port, SSLPort},
-		{certfile, PathToCertfile},
-		{cacertfile, PathToCACertfile},
-		{verify, verify_peer}
-	],
-	my_protocol, []
-).
-
-In this example we set the required `port` and `certfile`, but also
-the `cacertfile` containing the CACert.org root certificate, and
-the option to request the client certificate.
-
-If you enable the `{verify, verify_peer}` option and the client does
-not have a client certificate configured for your domain, then no
-certificate will be sent. This allows you to use SSL for more than
-just authenticated clients.
-
-=== Authentication
-
-To authenticate users, you must first save the certificate information
-required. If you have your users' certificate files, you can simply
-load the certificate and retrieve the information directly.
-
-.Retrieve the issuer ID from a certificate
-
-[source,erlang]
-----
-certfile_to_issuer_id(Filename) ->
-	{ok, Data} = file:read_file(Filename),
-	[{'Certificate', Cert, not_encrypted}] = public_key:pem_decode(Data),
-	{ok, IssuerID} = public_key:pkix_issuer_id(Cert, self),
-	IssuerID.
-----
-
-The `IssuerID` variable contains both the certificate serial number
-and the certificate issuer stored in a tuple, so this value alone can
-be used to uniquely identify the user certificate. You can save this
-value in a database, a configuration file or any other place where an
-Erlang term can be stored and retrieved.
-
-To retrieve the `IssuerID` from a running connection, you need to first
-retrieve the client certificate and then extract this information from
-it. Ranch does not provide a function to retrieve the client certificate.
-Instead you can use the `ssl:peercert/1` function. Once you have the
-certificate, you can again use the `public_key:pkix_issuer_id/2` to
-extract the `IssuerID` value.
-
-The following function returns the `IssuerID` or `false` if no client
-certificate was found. This snippet is intended to be used from your

-<h1 class="lined-header"><span>SSL client authentication</span></h1>
-
-<h2 id="_purpose">Purpose</h2>
-<p>SSL client authentication is a mechanism allowing applications to identify certificates. This allows your application to make sure that the client is an authorized certificate, but makes no claim about whether the user can be trusted. This can be combined with a password based authentication to attain greater security.</p>
-<p>The server only needs to retain the certificate serial number and the certificate issuer to authenticate the certificate. Together, they can be used to uniquely identify a certicate.</p>
-<p>As Ranch allows the same protocol code to be used for both SSL and non-SSL transports, you need to make sure you are in an SSL context before attempting to perform an SSL client authentication. This can be done by checking the return value of <code>Transport:name/0</code>.</p>
-<h2 id="_obtaining_client_certificates">Obtaining client certificates</h2>
-<p>You can obtain client certificates from various sources. You can generate them yourself, or you can use a service like CAcert.org which allows you to generate client and server certificates for free.</p>
-<p>Following are the steps you need to take to create a CAcert.org account, generate a certificate and install it in your favorite browser.</p>
-<ul><li>Open [CAcert.org](<a href="http://cacert.org)">http://cacert.org)</a> in your favorite browser
-</li>
-<li>Root Certificate link: install both certificates
-</li>
-<li>Join (Register an account)
-</li>
-<li>Verify your account (check your email inbox!)
-</li>
-<li>Log in
-</li>
-<li>Client Certificates: New
-</li>
-<li>Follow instructions to create the certificate
-</li>
-<li>Install the certificate in your browser
-</li>
-</ul>
-<p>You can optionally save the certificate for later use, for example to extract the <code>IssuerID</code> information as will be detailed later on.</p>
-<h2 id="_transport_configuration">Transport configuration</h2>
-<p>The SSL transport does not request a client certificate by default. You need to specify the <code>{verify, verify_peer}</code> option when starting the listener to enable this behavior.</p>

-<p>The <code>IssuerID</code> variable contains both the certificate serial number and the certificate issuer stored in a tuple, so this value alone can be used to uniquely identify the user certificate. You can save this value in a database, a configuration file or any other place where an Erlang term can be stored and retrieved.</p>
-<p>To retrieve the <code>IssuerID</code> from a running connection, you need to first retrieve the client certificate and then extract this information from it. Ranch does not provide a function to retrieve the client certificate. Instead you can use the <code>ssl:peercert/1</code> function. Once you have the certificate, you can again use the <code>public_key:pkix_issuer_id/2</code> to extract the <code>IssuerID</code> value.</p>
-<p>The following function returns the <code>IssuerID</code> or <code>false</code> if no client certificate was found. This snippet is intended to be used from your protocol code.</p>

-== Transports
-
-A transport defines the interface to interact with a socket.
-
-Transports can be used for connecting, listening and accepting
-connections, but also for receiving and sending data. Both
-passive and active mode are supported, although all sockets
-are initialized as passive.
-
-=== TCP transport
-
-The TCP transport is a thin wrapper around `gen_tcp`.
-
-=== SSL transport
-
-The SSL transport is a thin wrapper around `ssl`. It requires
-the `crypto`, `asn1`, `public_key` and `ssl` applications
-to be started. When starting an SSL listener, Ranch will attempt
-to automatically start them. It will not try to stop them when
-the listener is removed, however.
-
-.Starting the SSL application
-
-[source,erlang]
-ssl:start().
-
-In a proper OTP setting, you will need to make your application
-depend on the `crypto`, `public_key` and `ssl` applications.
-They will be started automatically when starting your release.
-
-The SSL transport `accept/2` function performs both transport
-and SSL accepts. Errors occurring during the SSL accept phase
-are returned as `{error, {ssl_accept, atom()}}` to differentiate
-on which socket the problem occurred.
-
-=== Sending and receiving data
-
-This section assumes that `Transport` is a valid transport handler
-(like `ranch_tcp` or `ranch_ssl`) and `Socket` is a connected
-socket obtained through the listener.
-
-You can send data to a socket by calling the `Transport:send/2`
-function. The data can be given as `iodata()`, which is defined as
-`binary() | iolist()`. All the following calls will work:
-
-.Sending data to the socket
-
-[source,erlang]
-----
-Transport:send(Socket, <<"Ranch is cool!">>).
-Transport:send(Socket, "Ranch is cool!").
-Transport:send(Socket, ["Ranch", ["is", "cool!"]]).
-Transport:send(Socket, ["Ranch", [<<"is">>, "cool!"]]).
-----
-
-You can receive data either in passive or in active mode. Passive mode
-means that you will perform a blocking `Transport:recv/3` call, while
-active mode means that you will receive the data as a message.
-
-By default, all data will be received as binary. It is possible to
-receive data as strings, although this is not recommended as binaries
-are a more efficient construct, especially for binary protocols.
-
-Receiving data using passive mode requires a single function call. The
-first argument is the socket, and the third argument is a timeout duration
-before the call returns with `{error, timeout}`.
-
-The second argument is the amount of data in bytes that we want to receive.
-The function will wait for data until it has received exactly this amount.
-If you are not expecting a precise size, you can specify 0 which will make
-this call return as soon as data was read, regardless of its size.
-
-.Receiving data from the socket in passive mode
-
-[source,erlang]
-{ok, Data} = Transport:recv(Socket, 0, 5000).
-
-Active mode requires you to inform the socket that you want to receive
-data as a message and to write the code to actually receive it.
-
-There are two kinds of active modes: `{active, once}` and
-`{active, true}`. The first will send a single message before going
-back to passive mode; the second will send messages indefinitely.
-We recommend not using the `{active, true}` mode as it could quickly
-flood your process mailbox. It's better to keep the data in the socket
-and read it only when required.
-
-Three different messages can be received:
-
-* `{OK, Socket, Data}`
-* `{Closed, Socket}`
-* `{Error, Socket, Reason}`
-
-The value of `OK`, `Closed` and `Error` can be different
-depending on the transport being used. To be able to properly match
-on them you must first call the `Transport:messages/0` function.
-
-.Retrieving the transport's active message identifiers
-
-[source,erlang]
-{OK, Closed, Error} = Transport:messages().
-
-To start receiving messages you will need to call the `Transport:setopts/2`
-function, and do so every time you want to receive data.
-
-.Receiving messages from the socket in active mode
-
-[source,erlang]
-----
-{OK, Closed, Error} = Transport:messages(),
-Transport:setopts(Socket, [{active, once}]),
-receive
-	{OK, Socket, Data} ->
-		io:format("data received: ~p~n", [Data]);
-	{Closed, Socket} ->
-		io:format("socket got closed!~n");
-	{Error, Socket, Reason} ->
-		io:format("error happened: ~p~n", [Reason])
-end.
-----
-
-You can easily integrate active sockets with existing Erlang code as all
-you really need is just a few more clauses when receiving messages.
-
-=== Sending files
-
-As in the previous section it is assumed `Transport` is a valid transport
-handler and `Socket` is a connected socket obtained through the listener.
-
-To send a whole file, with name `Filename`, over a socket:
-
-.Sending a file by filename
-
-[source,erlang]
-{ok, SentBytes} = Transport:sendfile(Socket, Filename).
-
-Or part of a file, with `Offset` greater than or equal to 0, `Bytes` number of
-bytes and chunks of size `ChunkSize`:
-
-.Sending part of a file by filename in chunks
-
-[source,erlang]
-Opts = [{chunk_size, ChunkSize}],
-{ok, SentBytes} = Transport:sendfile(Socket, Filename, Offset, Bytes, Opts).
-
-To improve efficiency when sending multiple parts of the same file it is also
-possible to use a file descriptor opened in raw mode:
-
-.Sending a file opened in raw mode
-
-[source,erlang]
-{ok, RawFile} = file:open(Filename, [raw, read, binary]),
-{ok, SentBytes} = Transport:sendfile(Socket, RawFile, Offset, Bytes, Opts).
-
-=== Writing a transport handler
-
-A transport handler is a module implementing the `ranch_transport` behavior.
-It defines a certain number of callbacks that must be written in order to
-allow transparent usage of the transport handler.
-
-The behavior doesn't define the socket options available when opening a
-socket. These do not need to be common to all transports as it's easy enough
-to write different initialization functions for the different transports that
-will be used. With one exception though. The `setopts/2` function *must*
-implement the `{active, once}` and the `{active, true}` options.
-
-If the transport handler doesn't have a native implementation of `sendfile/5` a
-fallback is available, `ranch_transport:sendfile/6`. The extra first argument
-is the transport's module. See `ranch_ssl` for an example.

-<p>A transport defines the interface to interact with a socket.</p>
-<p>Transports can be used for connecting, listening and accepting connections, but also for receiving and sending data. Both passive and active mode are supported, although all sockets are initialized as passive.</p>
-<h2 id="_tcp_transport">TCP transport</h2>
-<p>The TCP transport is a thin wrapper around <code>gen_tcp</code>.</p>
-<h2 id="_ssl_transport">SSL transport</h2>
-<p>The SSL transport is a thin wrapper around <code>ssl</code>. It requires the <code>crypto</code>, <code>asn1</code>, <code>public_key</code> and <code>ssl</code> applications to be started. When starting an SSL listener, Ranch will attempt to automatically start them. It will not try to stop them when the listener is removed, however.</p>

-<p>In a proper OTP setting, you will need to make your application depend on the <code>crypto</code>, <code>public_key</code> and <code>ssl</code> applications. They will be started automatically when starting your release.</p>
-<p>The SSL transport <code>accept/2</code> function performs both transport and SSL accepts. Errors occurring during the SSL accept phase are returned as <code>{error, {ssl_accept, atom()}}</code> to differentiate on which socket the problem occurred.</p>
-<h2 id="_sending_and_receiving_data">Sending and receiving data</h2>
-<p>This section assumes that <code>Transport</code> is a valid transport handler (like <code>ranch_tcp</code> or <code>ranch_ssl</code>) and <code>Socket</code> is a connected socket obtained through the listener.</p>
-<p>You can send data to a socket by calling the <code>Transport:send/2</code> function. The data can be given as <code>iodata()</code>, which is defined as <code>binary() | iolist()</code>. All the following calls will work:</p>

-<p>You can receive data either in passive or in active mode. Passive mode means that you will perform a blocking <code>Transport:recv/3</code> call, while active mode means that you will receive the data as a message.</p>
-<p>By default, all data will be received as binary. It is possible to receive data as strings, although this is not recommended as binaries are a more efficient construct, especially for binary protocols.</p>
-<p>Receiving data using passive mode requires a single function call. The first argument is the socket, and the third argument is a timeout duration before the call returns with <code>{error, timeout}</code>.</p>
-<p>The second argument is the amount of data in bytes that we want to receive. The function will wait for data until it has received exactly this amount. If you are not expecting a precise size, you can specify 0 which will make this call return as soon as data was read, regardless of its size.</p>

-<p>Active mode requires you to inform the socket that you want to receive data as a message and to write the code to actually receive it.</p>
-<p>There are two kinds of active modes: <code>{active, once}</code> and <code>{active, true}</code>. The first will send a single message before going back to passive mode; the second will send messages indefinitely. We recommend not using the <code>{active, true}</code> mode as it could quickly flood your process mailbox. It&apos;s better to keep the data in the socket and read it only when required.</p>
-<p>Three different messages can be received:</p>
-<ul><li><code>{OK, Socket, Data}</code>
-</li>
-<li><code>{Closed, Socket}</code>
-</li>
-<li><code>{Error, Socket, Reason}</code>
-</li>
-</ul>
-<p>The value of <code>OK</code>, <code>Closed</code> and <code>Error</code> can be different depending on the transport being used. To be able to properly match on them you must first call the <code>Transport:messages/0</code> function.</p>

-<h2 id="_writing_a_transport_handler">Writing a transport handler</h2>
-<p>A transport handler is a module implementing the <code>ranch_transport</code> behavior. It defines a certain number of callbacks that must be written in order to allow transparent usage of the transport handler.</p>
-<p>The behavior doesn&apos;t define the socket options available when opening a socket. These do not need to be common to all transports as it&apos;s easy enough to write different initialization functions for the different transports that will be used. With one exception though. The <code>setopts/2</code> function <strong>must</strong> implement the <code>{active, once}</code> and the <code>{active, true}</code> options.</p>
-<p>If the transport handler doesn&apos;t have a native implementation of <code>sendfile/5</code> a fallback is available, <code>ranch_transport:sendfile/6</code>. The extra first argument is the transport&apos;s module. See <code>ranch_ssl</code> for an example.</p>

-<p>Do not count this connection when limiting the number of connections.</p>
-<p>You can use this function for long-running connection processes which spend most of their time idling rather than consuming resources. This allows Ranch to accept a lot more connections without sacrificing the latency of the system.</p>

-<p>The change will be applied immediately. If the new value is smaller than the previous one, Ranch will not kill the extra connections, but will wait for them to terminate properly.</p>

-<p>Start listening for connections using the given transport and protocol. Returns the pid for this listener&apos;s supervisor.</p>
-<p>There are additional transport options that apply regardless of transport. They allow configuring how the connections are supervised, rate limited and more. Please consult the previous section for more details.</p>

-</dl>
-<p>Stop the given listener.</p>
-<p>The listener is stopped gracefully, first by closing the listening port, then by stopping the connection processes. These processes are stopped according to the <code>shutdown</code> transport option, which may be set to brutally kill all connection processes or give them some time to stop properly.</p>
-<p>This function does not return until the listener is completely stopped.</p>

-<p>ranch_tcp - TCP transport module</p>
-<h2 id="_description">Description</h2>
-<p>The <code>ranch_tcp</code> module implements a TCP Ranch transport.</p>
-<p>Note that due to bugs in OTP up to at least R16B02, it is recommended to disable async threads when using the <code>sendfile</code> function of this transport, as it can make the threads stuck indefinitely.</p>

-<p>Accept a connection on the given listening socket.</p>
-<p>The <code>accept_ack</code> callback will be used to initialize the socket after accepting the connection. This is most useful when the transport is not raw TCP, like with SSL for example.</p>

-</dd>
-</dl>
-<p>Change the controlling process for the given socket.</p>
-<p>The controlling process is the process that is allowed to perform operations on the socket, and that will receive messages from the socket when active mode is used. When the controlling process dies, the socket is closed.</p>

-<p>Receive data from the given socket when in passive mode.</p>
-<p>Trying to receive data from a socket that is in active mode will return an error.</p>
-<p>A length of 0 will return any data available on the socket.</p>
-<p>While it is possible to use the timeout value <code>infinity</code>, this is highly discouraged as this could cause your process to get stuck waiting for data that will never come. This may happen when a socket becomes half-open due to a crash of the remote endpoint. Wi-Fi going down is another common culprit of this issue.</p>

-== Embedded mode
-
-Embedded mode allows you to insert Ranch listeners directly
-in your supervision tree. This allows for greater fault tolerance
-control by permitting the shutdown of a listener due to the
-failure of another part of the application and vice versa.
-
-=== Embedding
-
-To embed Ranch in your application you can simply add the child specs
-to your supervision tree. This can all be done in the `init/1` function
-of one of your application supervisors.
-
-Ranch requires at the minimum two kinds of child specs for embedding.
-First, you need to add `ranch_sup` to your supervision tree, only once,
-regardless of the number of listeners you will use. Then you need to
-add the child specs for each listener.
-
-Ranch has a convenience function for getting the listeners child specs
-called `ranch:child_spec/6`, that works like `ranch:start_listener/6`,
-except that it doesn't start anything, it only returns child specs.
-
-As for `ranch_sup`, the child spec is simple enough to not require a
-convenience function.
-
-The following example adds both `ranch_sup` and one listener to another
-application's supervision tree.
-
-.Embed Ranch directly in your supervision tree
-
-[source,erlang]
-----
-init([]) ->
-	RanchSupSpec = {ranch_sup, {ranch_sup, start_link, []},
-		permanent, 5000, supervisor, [ranch_sup]},
-	ListenerSpec = ranch:child_spec(echo, 100,
-		ranch_tcp, [{port, 5555}],
-		echo_protocol, []
-	),
-	{ok, {{one_for_one, 10, 10}, [RanchSupSpec, ListenerSpec]}}.
-----
-
-Remember, you can add as many listener child specs as needed, but only
-one `ranch_sup` spec!
-
-It is recommended that your architecture makes sure that all listeners
-are restarted if `ranch_sup` fails. See the Ranch internals chapter for
-more details on how Ranch does it.

-== Internals
-
-This chapter may not apply to embedded Ranch as embedding allows you
-to use an architecture specific to your application, which may or may
-not be compatible with the description of the Ranch application.
-
-Note that for everything related to efficiency and performance,
-you should perform the benchmarks yourself to get the numbers that
-matter to you. Generic benchmarks found on the web may or may not
-be of use to you, you can never know until you benchmark your own
-system.
-
-=== Architecture
-
-Ranch is an OTP application.
-
-Like all OTP applications, Ranch has a top supervisor. It is responsible
-for supervising the `ranch_server` process and all the listeners that
-will be started.
-
-The `ranch_server` gen_server is a central process keeping track of the
-listeners and their acceptors. It does so through the use of a public ets
-table called `ranch_server`. The table is owned by the top supervisor
-to improve fault tolerance. This way if the `ranch_server` gen_server
-fails, it doesn't lose any information and the restarted process can
-continue as if nothing happened.
-
-Ranch uses a custom supervisor for managing connections. This supervisor
-keeps track of the number of connections and handles connection limits
-directly. While it is heavily optimized to perform the task of creating
-connection processes for accepted connections, it is still following the
-OTP principles and the usual `sys` and `supervisor` calls will work on
-it as expected.
-
-Listeners are grouped into the `ranch_listener_sup` supervisor and
-consist of three kinds of processes: the listener gen_server, the
-acceptor processes and the connection processes, both grouped under
-their own supervisor. All of these processes are registered to the
-`ranch_server` gen_server with varying amount of information.
-
-All socket operations, including listening for connections, go through
-transport handlers. Accepted connections are given to the protocol handler.
-Transport handlers are simple callback modules for performing operations on
-sockets. Protocol handlers start a new process, which receives socket
-ownership, with no requirements on how the code should be written inside
-that new process.
-
-=== Number of acceptors
-
-The second argument to `ranch:start_listener/6` is the number of
-processes that will be accepting connections. Care should be taken
-when choosing this number.
-
-First of all, it should not be confused with the maximum number
-of connections. Acceptor processes are only used for accepting and
-have nothing else in common with connection processes. Therefore
-there is nothing to be gained from setting this number too high,
-in fact it can slow everything else down.
-
-Second, this number should be high enough to allow Ranch to accept
-connections concurrently. But the number of cores available doesn't
-seem to be the only factor for choosing this number, as we can
-observe faster accepts if we have more acceptors than cores. It
-might be entirely dependent on the protocol, however.
-
-Our observations suggest that using 100 acceptors on modern hardware
-is a good solution, as it's big enough to always have acceptors ready
-and it's low enough that it doesn't have a negative impact on the
-system's performances.
-
-=== Platform-specific TCP features
-
-Some socket options are platform-specific and not supported by `inet`.
-They can be of interest because they generally are related to
-optimizations provided by the underlying OS. They can still be enabled
-thanks to the `raw` option, for which we will see an example.
-
-One of these features is `TCP_DEFER_ACCEPT` on Linux. It is a simplified
-accept mechanism which will wait for application data to come in before
-handing out the connection to the Erlang process.
-
-This is especially useful if you expect many connections to be mostly
-idle, perhaps part of a connection pool. They can be handled by the
-kernel directly until they send any real data, instead of allocating
-resources to idle connections.
-
-To enable this mechanism, the following option can be used.
-
-.Using raw transport options
-
-[source,erlang]
-{raw, 6, 9, << 30:32/native >>}
-
-It means go on layer 6, turn on option 9 with the given integer parameter.

-<p>This chapter may not apply to embedded Ranch as embedding allows you to use an architecture specific to your application, which may or may not be compatible with the description of the Ranch application.</p>
-<p>Note that for everything related to efficiency and performance, you should perform the benchmarks yourself to get the numbers that matter to you. Generic benchmarks found on the web may or may not be of use to you, you can never know until you benchmark your own system.</p>
-<h2 id="_architecture">Architecture</h2>
-<p>Ranch is an OTP application.</p>
-<p>Like all OTP applications, Ranch has a top supervisor. It is responsible for supervising the <code>ranch_server</code> process and all the listeners that will be started.</p>
-<p>The <code>ranch_server</code> gen_server is a central process keeping track of the listeners and their acceptors. It does so through the use of a public ets table called <code>ranch_server</code>. The table is owned by the top supervisor to improve fault tolerance. This way if the <code>ranch_server</code> gen_server fails, it doesn&apos;t lose any information and the restarted process can continue as if nothing happened.</p>
-<p>Ranch uses a custom supervisor for managing connections. This supervisor keeps track of the number of connections and handles connection limits directly. While it is heavily optimized to perform the task of creating connection processes for accepted connections, it is still following the OTP principles and the usual <code>sys</code> and <code>supervisor</code> calls will work on it as expected.</p>
-<p>Listeners are grouped into the <code>ranch_listener_sup</code> supervisor and consist of three kinds of processes: the listener gen_server, the acceptor processes and the connection processes, both grouped under their own supervisor. All of these processes are registered to the <code>ranch_server</code> gen_server with varying amount of information.</p>
-<p>All socket operations, including listening for connections, go through transport handlers. Accepted connections are given to the protocol handler. Transport handlers are simple callback modules for performing operations on sockets. Protocol handlers start a new process, which receives socket ownership, with no requirements on how the code should be written inside that new process.</p>
-<h2 id="_number_of_acceptors">Number of acceptors</h2>
-<p>The second argument to <code>ranch:start_listener/6</code> is the number of processes that will be accepting connections. Care should be taken when choosing this number.</p>
-<p>First of all, it should not be confused with the maximum number of connections. Acceptor processes are only used for accepting and have nothing else in common with connection processes. Therefore there is nothing to be gained from setting this number too high, in fact it can slow everything else down.</p>
-<p>Second, this number should be high enough to allow Ranch to accept connections concurrently. But the number of cores available doesn&apos;t seem to be the only factor for choosing this number, as we can observe faster accepts if we have more acceptors than cores. It might be entirely dependent on the protocol, however.</p>
-<p>Our observations suggest that using 100 acceptors on modern hardware is a good solution, as it&apos;s big enough to always have acceptors ready and it&apos;s low enough that it doesn&apos;t have a negative impact on the system&apos;s performances.</p>
-<h2 id="_platform_specific_tcp_features">Platform-specific TCP features</h2>
-<p>Some socket options are platform-specific and not supported by <code>inet</code>. They can be of interest because they generally are related to optimizations provided by the underlying OS. They can still be enabled thanks to the <code>raw</code> option, for which we will see an example.</p>
-<p>One of these features is <code>TCP_DEFER_ACCEPT</code> on Linux. It is a simplified accept mechanism which will wait for application data to come in before handing out the connection to the Erlang process.</p>
-<p>This is especially useful if you expect many connections to be mostly idle, perhaps part of a connection pool. They can be handled by the kernel directly until they send any real data, instead of allocating resources to idle connections.</p>
-<p>To enable this mechanism, the following option can be used.</p>

-== Introduction
-
-Ranch is a socket acceptor pool for TCP protocols.
-
-Ranch aims to provide everything you need to accept TCP connections
-with a small code base and low latency while being easy to use directly
-as an application or to embed into your own.
-
-=== Prerequisites
-
-It is assumed the developer already knows Erlang and has some experience
-with socket programming and TCP protocols.
-
-=== Supported platforms
-
-Ranch is tested and supported on Linux, FreeBSD, OSX and Windows.
-
-Ranch is developed for Erlang/OTP R16B+.
-
-There are known issues with the SSL application found in Erlang/OTP
-18.3.2 and 18.3.3. These versions are therefore not supported.
-
-Ranch may be compiled on earlier Erlang versions with small source code
-modifications but there is no guarantee that it will work as expected.
-
-=== Versioning
-
-Ranch uses http://semver.org/[Semantic Versioning 2.0.0]

-<p>There are three kinds of protocols:</p>
-<ul><li>Text protocols
-</li>
-<li>Schema-less binary protocols
-</li>
-<li>Schema-based binary protocols
-</li>
-</ul>
-<p>This chapter introduces the first two kinds. It will not cover more advanced topics such as continuations or parser generators.</p>
-<p>This chapter isn&apos;t specifically about Ranch, we assume here that you know how to read data from the socket. The data you read and the data that hasn&apos;t been parsed is saved in a buffer. Every time you read from the socket, the data read is appended to the buffer. What happens next depends on the kind of protocol. We will only cover the first two.</p>
-<h2 id="_parsing_text">Parsing text</h2>
-<p>Text protocols are generally line based. This means that we can&apos;t do anything with them until we receive the full line.</p>
-<p>A simple way to get a full line is to use <code>binary:split/{2,3}</code>.</p>

-<p>In the above example, we can have two results. Either there was a line break in the buffer and we get it split into two parts, the line and the rest of the buffer; or there was no line break in the buffer and we need to get more data from the socket.</p>
-<p>Next, we need to parse the line. The simplest way is to again split, here on space. The difference is that we want to split on all spaces character, as we want to tokenize the whole string.</p>

-<p>Binary protocols can be more varied, although most of them are pretty similar. The first four bytes of a frame tend to be the size of the frame, which is followed by a certain number of bytes for the type of frame and then various parameters.</p>
-<p>Sometimes the size of the frame includes the first four bytes, sometimes not. Other times this size is encoded over two bytes. And even other times little-endian is used instead of big-endian.</p>

-<p>Do not count this connection when limiting the number of connections.</p>
-<p>You can use this function for long-running connection processes which spend most of their time idling rather than consuming resources. This allows Ranch to accept a lot more connections without sacrificing the latency of the system.</p>

-</dd>
-</dl>
-<p>Set the max number of connections for the given listener.</p>
-<p>The change will be applied immediately. If the new value is smaller than the previous one, Ranch will not kill the extra connections, but will wait for them to terminate properly.</p>
-<h3 id="_set_protocol_options_ref__protoopts_____ok">set_protocol_options(Ref, ProtoOpts) -&gt; ok</h3>
-<dl><dt>Ref = ref()</dt>

-</dd>
-</dl>
-<p>Start listening for connections using the given transport and protocol. Returns the pid for this listener&apos;s supervisor.</p>
-<p>There are additional transport options that apply regardless of transport. They allow configuring how the connections are supervised, rate limited and more. Please consult the previous section for more details.</p>
-<h3 id="_stop_listener_ref_____ok____error__not_found">stop_listener(Ref) -&gt; ok | {error, not_found}</h3>
-<dl><dt>Ref = ref()</dt>
-<dd><p>Listener name.</p>
-</dd>
-</dl>
-<p>Stop the given listener.</p>
-<p>The listener is stopped gracefully, first by closing the listening port, then by stopping the connection processes. These processes are stopped according to the <code>shutdown</code> transport option, which may be set to brutally kill all connection processes or give them some time to stop properly.</p>
-<p>This function does not return until the listener is completely stopped.</p>

-<p>Start a new connection process for the given socket.</p>
-<p>The only purpose of this callback is to start a process that will handle the socket. It must spawn the process, link and then return the new pid. This function will always be called from inside a supervisor.</p>
-<p>This callback can also return two pids. The first pid is the pid of the process that will be supervised. The second pid is the pid of the process that will receive ownership of the socket. This second process must be a child of the first. This form is only available when <code>connection_type</code> is set to <code>supervisor</code>.</p>
-<p>If any other value is returned, the supervisor will close the socket and assume no process has been started.</p>
-<p>Do not perform any operations in this callback, as this would block the supervisor responsible for starting connection processes and degrade performance severely.</p>

-<h2 id="_name">Name</h2>
-<p>ranch_transport - behaviour for transport modules</p>
-<h2 id="_description">Description</h2>
-<p>The <code>ranch_transport</code> behaviour defines the interface used by Ranch transports.</p>
-<h2 id="_types">Types</h2>
-<h3 id="_sendfile_opts_______chunk_size__non_neg_integer">sendfile_opts() = [{chunk_size, non_neg_integer()}]</h3>
-<p>Options used by the sendfile function and callbacks.</p>
-<p>Allows configuring the chunk size, in bytes. Defaults to 8191 bytes.</p>
-<h2 id="_callbacks">Callbacks</h2>
-<h3 id="_accept_lsocket__timeout______ok__csocket_____error__closed___timeout___atom">accept(LSocket, Timeout) -&gt; {ok, CSocket} | {error, closed | timeout | atom()}</h3>
-<dl><dt>LSocket = CSocket = any()</dt>
-<dd><p>Listening socket.</p>
-</dd>
-<dt>Timeout = timeout()</dt>
-<dd><p>Accept timeout.</p>
-</dd>
-</dl>
-<p>Accept a connection on the given listening socket.</p>
-<p>The <code>accept_ack</code> callback will be used to initialize the socket after accepting the connection. This is most useful when the transport is not raw TCP, like with SSL for example.</p>
-<h3 id="_accept_ack_csocket__timeout_____ok">accept_ack(CSocket, Timeout) -&gt; ok</h3>
-<dl><dt>CSocket = any()</dt>
-<dd><p>Socket for this connection.</p>
-</dd>
-<dt>Timeout = timeout()</dt>
-<dd><p>Ack timeout.</p>
-</dd>
-</dl>
-<p>Perform post-accept initialization of the connection.</p>
-<p>This function will be called by connection processes before performing any socket operation. It allows transports that require extra initialization to perform their task and make the socket ready to use.</p>
-<h3 id="_close_socket_____ok">close(Socket) -&gt; ok</h3>
-<dl><dt>Socket = any()</dt>
-<dd><p>Socket opened with listen/1 or accept/2.</p>
-</dd>
-</dl>
-<p>Close the given socket.</p>
-<h3 id="_controlling_process_socket__pid_____ok____error__closed___not_owner___atom">controlling_process(Socket, Pid) -&gt; ok | {error, closed | not_owner | atom()}</h3>
-<dl><dt>Socket = any()</dt>
-<dd><p>Socket opened with listen/1 or accept/2.</p>
-</dd>
-<dt>Pid = pid()</dt>
-<dd><p>Pid of the new owner of the socket.</p>
-</dd>
-</dl>
-<p>Change the controlling process for the given socket.</p>
-<p>The controlling process is the process that is allowed to perform operations on the socket, and that will receive messages from the socket when active mode is used. When the controlling process dies, the socket is closed.</p>
-<h3 id="_listen_transopts______ok__lsocket_____error__atom">listen(TransOpts) -&gt; {ok, LSocket} | {error, atom()}</h3>
-<dl><dt>TransOpts = any()</dt>
-<dd><p>Transport options.</p>
-</dd>
-<dt>LSocket = any()</dt>
-<dd><p>Listening socket.</p>
-</dd>
-</dl>
-<p>Listen for connections on the given port.</p>
-<p>The port is given as part of the transport options under the key <code>port</code>. Any other option is transport dependent.</p>
-<p>The socket returned by this call can then be used to accept connections. It is not possible to send or receive data from the listening socket.</p>
-<h3 id="_messages_______ok__closed__error">messages() -&gt; {OK, Closed, Error}</h3>
-<dl><dt>OK = Closed = Error = atom()</dt>
-<dd><p>Tuple names.</p>
-</dd>
-</dl>
-<p>Return the atoms used to identify messages sent in active mode.</p>
-<h3 id="_name______name">name() -&gt; Name</h3>
-<dl><dt>Name = atom()</dt>
-<dd><p>Transport module name.</p>
-</dd>
-</dl>
-<p>Return the name of the transport.</p>
-<h3 id="_peername_csocket______ok___ip__port______error__atom">peername(CSocket) -&gt; {ok, {IP, Port}} | {error, atom()}</h3>
-<dl><dt>CSocket = any()</dt>
-<dd><p>Socket for this connection.</p>
-</dd>
-<dt>IP = inet:ip_address()</dt>
-<dd><p>IP of the remote endpoint.</p>
-</dd>
-<dt>Port = inet:port_number()</dt>
-<dd><p>Port of the remote endpoint.</p>
-</dd>
-</dl>
-<p>Return the IP and port of the remote endpoint.</p>
-<h3 id="_recv_csocket__length__timeout______ok__packet_____error__closed___timeout___atom">recv(CSocket, Length, Timeout) -&gt; {ok, Packet} | {error, closed | timeout | atom()}</h3>
-<dl><dt>CSocket = any()</dt>
-<dd><p>Socket for this connection.</p>
-</dd>
-<dt>Length = non_neg_integer()</dt>
-<dd><p>Requested length.</p>
-</dd>
-<dt>Timeout = timeout()</dt>
-<dd><p>Receive timeout.</p>
-</dd>
-<dt>Packet = iodata() | any()</dt>
-<dd><p>Data received.</p>
-</dd>
-</dl>
-<p>Receive data from the given socket when in passive mode.</p>
-<p>Trying to receive data from a socket that is in active mode will return an error.</p>
-<p>A length of 0 will return any data available on the socket.</p>
-<p>While it is possible to use the timeout value <code>infinity</code>, this is highly discouraged as this could cause your process to get stuck waiting for data that will never come. This may happen when a socket becomes half-open due to a crash of the remote endpoint. Wi-Fi going down is another common culprit of this issue.</p>
-<h3 id="_send_csocket__packet_____ok____error__atom">send(CSocket, Packet) -&gt; ok | {error, atom()}</h3>
-<dl><dt>CSocket = any()</dt>
-<dd><p>Socket for this connection.</p>
-</dd>
-<dt>Packet = iodata()</dt>
-<dd><p>Data to be sent.</p>

-</dd>
-</dl>
-<p>Send data from a file to the given socket.</p>
-<p>The file may be sent full or in parts, and may be specified by its filename or by an already open file descriptor.</p>
-<p>Transports that manipulate TCP directly may use the <code>file:sendfile/{2,4,5}</code> function, which calls the sendfile syscall where applicable (on Linux, for example). Other transports can use the <code>sendfile/6</code> function exported from this module.</p>
-<h3 id="_setopts_csocket__sockopts_____ok____error__atom">setopts(CSocket, SockOpts) -&gt; ok | {error, atom()}</h3>

-<dt>SockOpts = any()</dt>
-<dd><p>Socket options.</p>
-</dd>
-</dl>
-<p>Change options for the given socket.</p>
-<p>This is mainly useful for switching to active or passive mode or to set protocol-specific options.</p>
-<h3 id="_shutdown_csocket__how_____ok____error__atom">shutdown(CSocket, How) -&gt; ok | {error, atom()}</h3>
-<dl><dt>CSocket = any()</dt>

-</dd>
-<dt>How = read | write | read_write</dt>
-<dd><p>Which side(s) of the socket to close.</p>
-</dd>
-</dl>
-<p>Immediately close the socket in one or two directions.</p>
-<h3 id="_sockname_socket______ok___ip__port______error__atom">sockname(Socket) -&gt; {ok, {IP, Port}} | {error, atom()}</h3>

-<dt>Port = inet:port_number()</dt>
-<dd><p>Port of the local endpoint.</p>
-</dd>
-</dl>
-<p>Return the IP and port of the local endpoint.</p>
-<h2 id="_exports">Exports</h2>
-<h3 id="_sendfile_transport__csocket__file__offset__bytes__sfopts______ok__sentbytes_____error__atom">sendfile(Transport, CSocket, File, Offset, Bytes, SfOpts) -&gt; {ok, SentBytes} | {error, atom()}</h3>

+== Embedded mode
+
+Embedded mode allows you to insert Ranch listeners directly
+in your supervision tree. This allows for greater fault tolerance
+control by permitting the shutdown of a listener due to the
+failure of another part of the application and vice versa.
+
+However, just as for non-embedded listeners that were started via
+`ranch:start_listener/5`, it is required that the `ranch` application
+is running before you can start embedded listeners. Furthermore,
+this also means that embedded listeners will restart when `ranch_sup` fails.
+
+WARNING: By using embedded mode, it is possible to start a listener with the same name
+as an already existing listener. This will corrupt the information Ranch
+keeps for that listener, so you should take care to ensure unique listener
+names yourself. A good way to achieve this is by combining the embedded
+listener's name with `?MODULE`, or the name of the application it is used
+in.
+
+=== Embedding
+
+To embed Ranch in your application you can simply add the child specs
+to your supervision tree. This can all be done in the `init/1` function
+of one of your application supervisors.
+
+Ranch has a convenience function for getting the listeners child specs
+called `ranch:child_spec/5`, that works like `ranch:start_listener/5`,
+except that it doesn't start anything, it only returns child specs.
+
+The following example adds one listener to another application's
+supervision tree.
+
+.Embed Ranch directly in your supervision tree
+
+[source,erlang]
+----
+init([]) ->
+	ListenerSpec = ranch:child_spec({?MODULE, echo},
+		ranch_tcp, #{socket_opts => [{port, 5555}]},
+		echo_protocol, []
+	),
+	{ok, {#{}, [ListenerSpec]}}.
+----
+
+Embedded listeners cannot be stopped via `ranch:stop_listener/1`. Instead,
+are to be stopped as part of the shutdown of your application's supervison
+tree.

 <p>Listeners are grouped into the <code>ranch_listener_sup</code> supervisor and consist of three kinds of processes: the listener gen_server, the acceptor processes and the connection processes, both grouped under their own supervisor. All of these processes are registered to the <code>ranch_server</code> gen_server with varying amount of information.</p>
 <p>All socket operations, including listening for connections, go through transport handlers. Accepted connections are given to the protocol handler. Transport handlers are simple callback modules for performing operations on sockets.

+<p>The second argument to <code>ranch:start_listener/5</code> is the number of processes that will be accepting connections. Care should be taken when choosing this number.</p>
 <p>First of all, it should not be confused with the maximum number of connections. Acceptor processes are only used for accepting and have nothing else in common with connection processes. Therefore there is nothing to be gained from setting this number too high, in fact it can slow everything else down.</p>
 <p>Second, this number should be high enough to allow Ranch to accept connections concurrently. But the number of cores available doesn&apos;t seem to be the only factor for choosing this number, as we can observe faster accepts if we have more acceptors than cores. It might be entirely dependent on the protocol, however.</p>
 <p>Our observations suggest that using 100 acceptors on modern hardware is a good solution, as it&apos;s big enough to always have acceptors ready and it&apos;s low enough that it doesn&apos;t have a negative impact on the system&apos;s performances.</p>

 === Accepting connections on an existing socket
 
-If you want to accept connections on an existing socket, you can use the
-`socket` transport option, which should just be the relevant data returned
-from the connect function for the transport or the underlying socket library
-(`gen_tcp:connect`, `ssl:connect`). The accept function will then be
-called on the passed in socket. You should connect the socket in
-`{active, false}` mode, as well.
-
-Note, however, that because of a bug in SSL, you cannot change ownership of an
-SSL listen socket prior to R16. Ranch will catch the error thrown, but the
-owner of the SSL socket will remain as whatever process created the socket.
-However, this will not affect accept behaviour unless the owner process dies,
-in which case the socket is closed. Therefore, to use this feature with SSL
-with an erlang release prior to R16, ensure that the SSL socket is opened in a
-persistant process.
+If you want to accept connections on an existing socket, you can write
+a custom `ranch_transport` implementation that fetches or otherwise
+acquires a listening socket in the `listen/1` callback and returns it
+in the form of `{ok, ListenSocket}`.
+
+The custom `listen/1` function must ensure that the listener process
+(usually the process calling it) is also made the controlling process
+of the socket it returns. Failing to do so will result in stop/start
+and suspend/resume not working properly for that listener.

-<p>If you want to accept connections on an existing socket, you can use the <code>socket</code> transport option, which should just be the relevant data returned from the connect function for the transport or the underlying socket library (<code>gen_tcp:connect</code>, <code>ssl:connect</code>). The accept function will then be called on the passed in socket. You should connect the socket in <code>{active, false}</code> mode, as well.</p>
-<p>Note, however, that because of a bug in SSL, you cannot change ownership of an SSL listen socket prior to R16. Ranch will catch the error thrown, but the owner of the SSL socket will remain as whatever process created the socket. However, this will not affect accept behaviour unless the owner process dies, in which case the socket is closed. Therefore, to use this feature with SSL with an erlang release prior to R16, ensure that the SSL socket is opened in a persistant process.</p>
+<p>If you want to accept connections on an existing socket, you can write a custom <code>ranch_transport</code> implementation that fetches or otherwise acquires a listening socket in the <code>listen/1</code> callback and returns it in the form of <code>{ok, ListenSocket}</code>.</p>
+<p>The custom <code>listen/1</code> function must ensure that the listener process (usually the process calling it) is also made the controlling process of the socket it returns. Failing to do so will result in stop/start and suspend/resume not working properly for that listener.</p>

+[appendix]
+== Migrating from Ranch 1.5 to 1.6
+
+Ranch 1.6 added the ability to suspend and resume listeners.
+It also deprecates a number of features and add interfaces
+that will be used in Ranch 2.0.
+
+Ranch 1.6 is compatible with Erlang/OTP 18.0 onward. Support
+for older releases has been removed.
+
+=== Features added
+
+* Listeners can now be suspended/resumed without stopping existing
+  connection processes. This effectively closes the listening socket
+  and stops the acceptor processes.
+
+* Transport options can now be updated for suspended listeners.
+
+* The `Socket` argument given when the protocol starts has been
+  deprecated. In Ranch 2.0 the socket will be obtainable only
+  by calling `ranch:handshake/1,2`.
+
+* Ranch-specific transport options and socket options are now
+  better separated. When passing Ranch-specific transport options,
+  Ranch now expects to receive a map, in which case socket
+  options are passed in the `socket_opts` value. When there
+  are only socket options they can be passed to Ranch directly
+  as a convenience.
+
+* Any future transport option will only be added to the map
+  type. This includes transport options added in this release.
+
+* The transport option `ack_timeout` was renamed to `handshake_timeout`
+  in the map type.
+
+* The `cacerts` socket option is now silenced in error logs
+  just like the `certs` and `key` options.
+
+* The manual has been heavily updated and now features one
+  manual page per function and module, complete with a per-function
+  changelog, examples and more.
+
+=== Experimental features added
+
+* It is now possible to configure the restart intensity for
+  `ranch_sup` using the OTP application environment. This
+  feature will remain undocumented unless there is popular
+  demand for it.
+
+* Add the transport option `logger` that allows configuring
+  which logger module will be used. The logger module must
+  follow the interface of the new `logger` module in Erlang/OTP 21,
+  or be set to `error_logger` to keep the old behavior.
+
+=== Changed behaviors
+
+* Transport modules must now implement `Transport:handshake/2,3`
+  which deprecates and will replace `Transport:accept_ack/1` in
+  Ranch 2.0. It returns a new socket and can therefore be used
+  for implementing TLS upgrade mechanisms.
+
+=== New functions
+
+* The functions `ranch:suspend_listener/1` and `ranch:resume_listener/1`
+  were added. In addition the function `ranch:get_state/1` can be used
+  to obtain the running state of a listener.
+
+* A function `ranch:wait_for_connections/3` was added.
+
+* A function `ranch:handshake/1,2` was added to replace the
+  function `ranch:accept_ack/1`.
+
+=== Bugs fixed
+
+* The specs for the function `Transport:sendfile/2,4,5` have been
+  corrected. The type used for the filename was too restricting.

+
+<p>Ranch 1.6 added the ability to suspend and resume listeners. It also deprecates a number of features and add interfaces that will be used in Ranch 2.0.</p>
+<p>Ranch 1.6 is compatible with Erlang/OTP 18.0 onward. Support for older releases has been removed.</p>
+<h2 id="_features_added">Features added</h2>
+<ul><li>Listeners can now be suspended/resumed without stopping existing connection processes. This effectively closes the listening socket and stops the acceptor processes.
+</li>
+<li>Transport options can now be updated for suspended listeners.
+</li>
+<li>The <code>Socket</code> argument given when the protocol starts has been deprecated. In Ranch 2.0 the socket will be obtainable only by calling <code>ranch:handshake/1,2</code>.
+</li>
+<li>Ranch-specific transport options and socket options are now better separated. When passing Ranch-specific transport options, Ranch now expects to receive a map, in which case socket options are passed in the <code>socket_opts</code> value. When there are only socket options they can be passed to Ranch directly as a convenience.
+</li>
+<li>Any future transport option will only be added to the map type. This includes transport options added in this release.
+</li>
+<li>The transport option <code>ack_timeout</code> was renamed to <code>handshake_timeout</code> in the map type.
+</li>
+<li>The <code>cacerts</code> socket option is now silenced in error logs just like the <code>certs</code> and <code>key</code> options.
+</li>
+<li>The manual has been heavily updated and now features one manual page per function and module, complete with a per-function changelog, examples and more.
+</li>
+</ul>
+<h2 id="_experimental_features_added">Experimental features added</h2>
+<ul><li>It is now possible to configure the restart intensity for <code>ranch_sup</code> using the OTP application environment. This feature will remain undocumented unless there is popular demand for it.
+</li>
+<li>Add the transport option <code>logger</code> that allows configuring which logger module will be used. The logger module must follow the interface of the new <code>logger</code> module in Erlang/OTP 21, or be set to <code>error_logger</code> to keep the old behavior.
+</li>
+</ul>
+<h2 id="_changed_behaviors">Changed behaviors</h2>
+<ul><li>Transport modules must now implement <code>Transport:handshake/2,3</code> which deprecates and will replace <code>Transport:accept_ack/1</code> in Ranch 2.0. It returns a new socket and can therefore be used for implementing TLS upgrade mechanisms.
+</li>
+</ul>
+<h2 id="_new_functions">New functions</h2>
+<ul><li>The functions <code>ranch:suspend_listener/1</code> and <code>ranch:resume_listener/1</code> were added. In addition the function <code>ranch:get_state/1</code> can be used to obtain the running state of a listener.
+</li>
+<li>A function <code>ranch:wait_for_connections/3</code> was added.
+</li>
+<li>A function <code>ranch:handshake/1,2</code> was added to replace the function <code>ranch:accept_ack/1</code>.
+</li>
+</ul>
+<h2 id="_bugs_fixed">Bugs fixed</h2>
+<ul><li>The specs for the function <code>Transport:sendfile/2,4,5</code> have been corrected. The type used for the filename was too restricting.
+</li>
+</ul>

+== Migrating from Ranch 1.6 to 1.7
+
+Ranch 1.7 adds built-in support for the PROXY protocol.
+
+The PROXY protocol is a simple and efficient way for proxies
+to transmit information about the client.
+
+While a third-party library already existed, it was not
+entirely compatible with the Ranch interface, in particular
+when socket active mode was involved. This new implementation
+fixes that and supports the full protocol with as little
+overhead as possible compared to normal operations: just one
+extra function call.
+
+Ranch 1.7 is compatible with Erlang/OTP 19.0 onward. Support
+for Erlang/OTP 18 has been removed.
+
+=== Features added
+
+* Full support for the PROXY protocol was added.
+
+=== New functions
+
+* Add the function `ranch:recv_proxy_header/2` to receive
+  the PROXY protocol header and parse it. It must be called
+  before `ranch:handshake/1,2`.
+
+* Add the functions `ranch_proxy_header:parse/1` and
+  `ranch_proxy_header:header/1,2` to parse and build a
+  PROXY protocol header, respectively.
+
+=== Bugs fixed
+
+* Fix a race condition when the listener is restarted
+  after `ranch_listener_sup` crashes. This resulted in
+  the original options being used even if the options
+  were updated at runtime.
+
+* Make the acceptors exit instead of crash when the
+  listening socket has been closed to prevent
+  unnecessary logs.
+
+* Fix an issue where listener information would not get
+  cleaned up when an embedded listener was stopped. This
+  was fixed in Ranch 1.6.2.

+[appendix]
+== Migrating from Ranch 1.7 to Ranch 2.0
+
+Ranch 2.0 adds support for multiple connection supervisors.
+
+Ranch 1.x had a bottleneck because it used only a single
+connection supervisor. This was more evident when many
+connections were dropped at once as the supervisor couldn't
+keep up and failed to accept new connections while cleaning
+up the old ones. Ranch 2.0 behaves much better in this scenario
+by default. Multiple connection supervisors also helps with
+concurrently accepting new connections.
+
+Ranch 2.0 also adds experimental support for opening more
+than one listening socket on a single port.
+
+Starting with Ranch 2.0 we are also providing a Prometheus
+collector as a separate project as well as a Grafana
+dashboard.
+
+Ranch 2.0 is compatible with Erlang/OTP 21.0 onward. Support
+for Erlang/OTP 19 and 20 has been removed.
+
+=== Features added
+
+* The `num_conns_sups` option has been added. It allows
+  configuring the number of connection supervisors. It
+  now defaults to `num_accceptors`. The old behavior can
+  be obtained by setting this value to 1.
+
+* The `logger` option is no longer experimental. It now
+  defaults to `logger` instead of `error_logger`.
+
+* UNIX domain sockets are now supported.
+
+* The active N socket option is now supported. It requires
+  Erlang/OTP 21.3 or above for TLS, however.
+
+* Embedded listeners are now failing in a predictable
+  manner when `ranch_server` goes down. It is no longer
+  necessary to embed `ranch_sup` and the recommendation
+  is now to just start Ranch normally when using embedded
+  listeners.
+
+=== Experimental features added
+
+* The experimental `num_listen_sockets` option has been
+  added. It allows opening more than one listening socket
+  per listener. It can only be used alongside the Linux
+  `SO_REUSEPORT` socket option or equivalent. It allows
+  working around a bottleneck in the kernel and maximizes
+  resource usage, leading to increased rates for accepting
+  new connections.
+
+=== Features removed
+
+* The `socket` option was removed. A more viable solution
+  is to define a custom transport module that returns a fresh
+  socket when `Transport:listen/1` is called.
+
+=== Changed behaviors
+
+* The callback function `Transport:listen/1` and its
+  implementations in `ranch_tcp` and `ranch_ssl` have changed
+  to accept a map of transport options instead of only
+  socket options.
+
+* The callback function `Transport:messages/0` return value
+  now include the tag used for passive messages.
+
+* The `Socket` argument was removed from `Protocol:start_link/3`.
+  The socket must now be obtained by calling `ranch:handshake/1,2`.
+
+=== Changed functions
+
+* The `NumAcceptors` argument was removed from `ranch:start_listener/5`
+  and `ranch:child_spec/5` and moved to the transport options.
+
+* Ranch options can no longer be passed along with socket options
+  as a proplist. The only forms allowed are now the `ranch:opts()`
+  map or only socket options as-is. Individual transport options
+  are now validated as well. The `ranch:opts()` map must
+  be used when socket options also use a map. This applies to the
+  `ranch:start_listener/5`, `ranch:child_spec/5` and
+  `ranch:set_transport_options/2` functions.
+
+* The function `ranch:info/1,2` now returns a map containing
+  each listener's information rather than a list of key/values.
+  The key `num_acceptors` was removed as it can be found in the
+  transport options.
+
+* The function `ranch:set_transport_options/2` no longer requires
+  the listener to be suspended. Which options apply immediately,
+  on suspend/resume or on restart has been documented. Some work
+  has also been done to make these option changes more predictable.
+
+=== Removed functions
+
+* The function `ranch:accept_ack/1` has been removed in favor
+  of `ranch:handshake/1,2`.
+
+=== Bugs fixed
+
+* Repeatedly calling `ranch:remove_connection/1` from a connection
+  process would crash the respective connection supervisor. This has
+  now been fixed.
+
+* When a connection process was failing to start, the socket was
+  not closed and this lead to leaking sockets. This is now corrected.
+
+=== Other changes
+
+* Connection draining has now been documented in the guide
+  following user feedback and discussions.
+
+* Ranch is now tested against `havoc`, a chaos monkey style
+  testing tool. Currently includes three scenarios: normal
+  TCP and TLS listeners and embedded TCP listener. This new
+  test suite helped uncover a misplaced `monitor/2` call
+  added during the development of Ranch 2.0.
+
+* The supervisor for acceptors and the parent supervisor for
+  connection supervisors now have an adaptive restart
+  intensity limit set to `1 + ceil(math:log2(NumChildren))`
+  to allow room for errors when they have many children.
+
+* Ranch now uses stricter compiler options. Missing function
+  specs were added to internal modules.
+
+* Ranch now calls `ssl:handshake/1,2,3` instead of
+  `ssl:ssl_accept/1,2`.
+
+* The `ranch_ssl:ssl_opt()` type has been updated to conform
+  with Erlang/OTP 22.0.

+
+<p>Ranch 2.0 adds support for multiple connection supervisors.</p>
+<p>Ranch 1.x had a bottleneck because it used only a single connection supervisor. This was more evident when many connections were dropped at once as the supervisor couldn&apos;t keep up and failed to accept new connections while cleaning up the old ones. Ranch 2.0 behaves much better in this scenario by default. Multiple connection supervisors also helps with concurrently accepting new connections.</p>
+<p>Ranch 2.0 also adds experimental support for opening more than one listening socket on a single port.</p>
+<p>Starting with Ranch 2.0 we are also providing a Prometheus collector as a separate project as well as a Grafana dashboard.</p>
+<p>Ranch 2.0 is compatible with Erlang/OTP 21.0 onward. Support for Erlang/OTP 19 and 20 has been removed.</p>
+<h2 id="_features_added">Features added</h2>
+<ul><li>The <code>num_conns_sups</code> option has been added. It allows configuring the number of connection supervisors. It now defaults to <code>num_accceptors</code>. The old behavior can be obtained by setting this value to 1.
+</li>
+<li>The <code>logger</code> option is no longer experimental. It now defaults to <code>logger</code> instead of <code>error_logger</code>.
+</li>
+<li>UNIX domain sockets are now supported.
+</li>
+<li>The active N socket option is now supported. It requires Erlang/OTP 21.3 or above for TLS, however.
+</li>
+<li>Embedded listeners are now failing in a predictable manner when <code>ranch_server</code> goes down. It is no longer necessary to embed <code>ranch_sup</code> and the recommendation is now to just start Ranch normally when using embedded listeners.
+</li>
+</ul>
+<h2 id="_experimental_features_added">Experimental features added</h2>
+<ul><li>The experimental <code>num_listen_sockets</code> option has been added. It allows opening more than one listening socket per listener. It can only be used alongside the Linux <code>SO_REUSEPORT</code> socket option or equivalent. It allows working around a bottleneck in the kernel and maximizes resource usage, leading to increased rates for accepting new connections.
+</li>
+</ul>
+<h2 id="_features_removed">Features removed</h2>
+<ul><li>The <code>socket</code> option was removed. A more viable solution is to define a custom transport module that returns a fresh socket when <code>Transport:listen/1</code> is called.
+</li>
+</ul>
+<h2 id="_changed_behaviors">Changed behaviors</h2>
+<ul><li>The callback function <code>Transport:listen/1</code> and its implementations in <code>ranch_tcp</code> and <code>ranch_ssl</code> have changed to accept a map of transport options instead of only socket options.
+</li>
+<li>The callback function <code>Transport:messages/0</code> return value now include the tag used for passive messages.
+</li>
+<li>The <code>Socket</code> argument was removed from <code>Protocol:start_link/3</code>. The socket must now be obtained by calling <code>ranch:handshake/1,2</code>.
+</li>
+</ul>
+<h2 id="_changed_functions">Changed functions</h2>
+<ul><li>The <code>NumAcceptors</code> argument was removed from <code>ranch:start_listener/5</code> and <code>ranch:child_spec/5</code> and moved to the transport options.
+</li>
+<li>Ranch options can no longer be passed along with socket options as a proplist. The only forms allowed are now the <code>ranch:opts()</code> map or only socket options as-is. Individual transport options are now validated as well. The <code>ranch:opts()</code> map must be used when socket options also use a map. This applies to the <code>ranch:start_listener/5</code>, <code>ranch:child_spec/5</code> and <code>ranch:set_transport_options/2</code> functions.
+</li>
+<li>The function <code>ranch:info/1,2</code> now returns a map containing each listener&apos;s information rather than a list of key/values. The key <code>num_acceptors</code> was removed as it can be found in the transport options.
+</li>
+<li>The function <code>ranch:set_transport_options/2</code> no longer requires the listener to be suspended. Which options apply immediately, on suspend/resume or on restart has been documented. Some work has also been done to make these option changes more predictable.
+</li>
+</ul>
+<h2 id="_removed_functions">Removed functions</h2>
+<ul><li>The function <code>ranch:accept_ack/1</code> has been removed in favor of <code>ranch:handshake/1,2</code>.
+</li>
+</ul>
+<h2 id="_bugs_fixed">Bugs fixed</h2>
+<ul><li>Repeatedly calling <code>ranch:remove_connection/1</code> from a connection process would crash the respective connection supervisor. This has now been fixed.
+</li>
+<li>When a connection process was failing to start, the socket was not closed and this lead to leaking sockets. This is now corrected.
+</li>
+</ul>
+<h2 id="_other_changes">Other changes</h2>
+<ul><li>Connection draining has now been documented in the guide following user feedback and discussions.
+</li>
+<li>Ranch is now tested against <code>havoc</code>, a chaos monkey style testing tool. Currently includes three scenarios: normal TCP and TLS listeners and embedded TCP listener. This new test suite helped uncover a misplaced <code>monitor/2</code> call added during the development of Ranch 2.0.
+</li>
+<li>The supervisor for acceptors and the parent supervisor for connection supervisors now have an adaptive restart intensity limit set to <code>1 + ceil(math:log2(NumChildren))</code> to allow room for errors when they have many children.
+</li>
+<li>Ranch now uses stricter compiler options. Missing function specs were added to internal modules.
+</li>
+<li>Ranch now calls <code>ssl:handshake/1,2,3</code> instead of <code>ssl:ssl_accept/1,2</code>.
+</li>
+<li>The <code>ranch_ssl:ssl_opt()</code> type has been updated to conform with Erlang/OTP 22.0.
+</li>

-<p>Embedded mode allows you to insert Ranch listeners directly in your supervision tree. This allows for greater fault tolerance control by permitting the shutdown of a listener due to the failure of another part of the application and vice versa.</p>
-<h2 id="_embedding">Embedding</h2>
-<p>To embed Ranch in your application you can simply add the child specs to your supervision tree. This can all be done in the <code>init/1</code> function of one of your application supervisors.</p>
-<p>Ranch requires at the minimum two kinds of child specs for embedding. First, you need to add <code>ranch_sup</code> to your supervision tree, only once, regardless of the number of listeners you will use. Then you need to add the child specs for each listener.</p>
-<p>Ranch has a convenience function for getting the listeners child specs called <code>ranch:child_spec/6</code>, that works like <code>ranch:start_listener/6</code>, except that it doesn&apos;t start anything, it only returns child specs.</p>
-<p>As for <code>ranch_sup</code>, the child spec is simple enough to not require a convenience function.</p>
-<p>The following example adds both <code>ranch_sup</code> and one listener to another application&apos;s supervision tree.</p>

 <p>This chapter isn&apos;t specifically about Ranch, we assume here that you know how to read data from the socket. The data you read and the data that hasn&apos;t been parsed is saved in a buffer. Every time you read from the socket, the data read is appended to the buffer. What happens next depends on the kind of protocol. We will only cover the first two.</p>

 <p>Text protocols are generally line based. This means that we can&apos;t do anything with them until we receive the full line.</p>

 <h2 id="_writing_a_transport_handler">Writing a transport handler</h2>
 <p>A transport handler is a module implementing the <code>ranch_transport</code> behavior. It defines a certain number of callbacks that must be written in order to allow transparent usage of the transport handler.</p>
 <p>The behavior doesn&apos;t define the socket options available when opening a socket. These do not need to be common to all transports as it&apos;s easy enough to write different initialization functions for the different transports that will be used. With one exception though. The <code>setopts/2</code> function <strong>must</strong> implement the <code>{active, once}</code> and the <code>{active, true}</code> options.</p>

+<p>Perform the transport handshake.</p>

-<p>Return the value for the given binding.</p>
+<p>Wait for a specific number of connections.</p>
+<p>This function waits until the number of connections on the given listener becomes higher than, equal to or lower than the given number. It never returns otherwise.</p>
+<p>This function can be used to gracefully shutdown a listener by first suspending the listener and then waiting for connections to terminate before finally stopping the listener.</p>
+<!-- @todo The suspend/wait/stop pattern should be tested.-->
 <h2 id="_arguments">Arguments</h2>
-<dl><dt>Name</dt>
-<dd><p>Desired binding name as an atom.</p>
+<dl><dt>Ref</dt>
+<dd><p>The listener name.</p>
 </dd>
-<dt>Req</dt>
-<dd><p>The Req object.</p>
+<dt>Operator</dt>
+<dd><p>The operator to use for the comparison.</p>
 </dd>
-<dt>Default</dt>
-<dd><p>Default value returned when the binding is missing.</p>
+<dt>NumConns</dt>
+<dd><p>The number of connections to reach.</p>
 </dd>
 </dl>
 <h2 id="_return_value">Return value</h2>
-<p>By default the value is a case sensitive binary string, however constraints may change the type of this value (for example automatically converting numbers to integer).</p>
+<p>The atom <code>ok</code> is always returned. It can be safely ignored.</p>
 <h2 id="_changelog">Changelog</h2>
-<ul><li><strong>2.0</strong>: Only the value is returned, it is no longer wrapped in a tuple.

 <p>The only purpose of this callback is to start a process that will handle the socket. It must spawn the process, link and then return the new pid. This function will always be called from inside a supervisor.</p>
 <p>This callback can also return two pids. The first pid is the pid of the process that will be supervised. The second pid is the pid of the process that will receive ownership of the socket. This second process must be a child of the first. This form is only available when <code>connection_type</code> is set to <code>supervisor</code>.</p>
 <p>If any other value is returned, the supervisor will close the socket and assume no process has been started.</p>
 <p>Do not perform any operations in this callback, as this would block the supervisor responsible for starting connection processes and degrade performance severely.</p>

+<p>Receive a packet from the socket in passive mode.</p>
+<p>Attempting to receive data from a socket that is in active mode will return an error.</p>
+<p>A length of 0 will return the data available on the socket as soon as possible, regardless of length.</p>
+<p>While it is possible to use the timeout value <code>infinity</code>, it is highly discouraged as it could cause your process to get stuck waiting for data that will never come. This may happen when a socket becomes half-open due to a crash of the remote endpoint. Wi-Fi going down is another common culprit.</p>

-Git and Erlang/OTP must also be installed.
-Some functionality requires that Autoconf 2.59 or later be installed, in order to compile Erlang/OTP. Erlang/OTP may have further requirements depending on your needs.

-Building your project Erlang.mk is first and foremost a build tool. It is especially tailored for Erlang developers and follows widely accepted practices in the Erlang community.
-Erlang.mk will happily build all Erlang-specific files you throw at it. Other kinds of files too, like C or C++ code when you are working on a NIF or a port driver.</description>

+      <description>Purpose SSL client authentication is a mechanism allowing applications to identify certificates. This allows your application to make sure that the client is an authorized certificate, but makes no claim about whether the user can be trusted. This can be combined with a password based authentication to attain greater security.
+The server only needs to retain the certificate serial number and the certificate issuer to authenticate the certificate. Together, they can be used to uniquely identify a certicate.</description>

However, you may want to stop a listener in a graceful fashion, ie by not accepting any new connections, but allowing the existing connection processes to exit by themselves instead of being killed.
+For this purpose, you should first suspend the listener you wish to stop gracefully, and then wait for its connection count to drop to zero.</description>

+      <description>Ranch 1.6 added the ability to suspend and resume listeners. It also deprecates a number of features and add interfaces that will be used in Ranch 2.0.
+Ranch 1.6 is compatible with Erlang/OTP 18.0 onward. Support for older releases has been removed.
+Features added Listeners can now be suspended/resumed without stopping existing connection processes. This effectively closes the listening socket and stops the acceptor processes.  Transport options can now be updated for suspended listeners.</description>

-As Websocket connections are established through the HTTP/1.1 upgrade mechanism, Websocket handlers need to be able to first receive the HTTP request for the upgrade, before switching to Websocket and taking over the connection.

-Erlang.mk is fast Erlang.mk is as fast as it gets.
-Erlang.mk will group the compilation of files so as to avoid running the BEAM more than necessary. This saves many seconds compared to traditional Makefiles, even on small projects.
-Erlang.mk will not try to be too smart. It provides a simple solution that works for most people, and gives additional options for projects that run into edge cases, often in the form of extra variables or rules to be defined.</description>

-Before Erlang.mk Erlang.mk originates from the Cowboy project. Cowboy started as a Rebar project and I, Loïc Hoguin, was very happy with it for a couple years. Over time however I started getting annoyed and frustrated by a number of things, including bad defaults, changing defaults and overall slowness.
-In particular, at the time I gave up on Rebar, the Cowboy test suite was taking about five minutes to run.</description>

-Callbacks Middlewares implement the following interface:
-execute(Req, Env) -&amp;gt; {ok, Req, Env} | {suspend, module(), atom(), [any()]} | {stop, Req} Req :: cowboy_req:req() Env :: cowboy_middleware:env()  The execute/2 is the only callback that needs to be implemented. It must execute the middleware and return with instructions for Cowboy.</description>

-Git and Erlang/OTP must also be installed.
-Some functionality requires that Autoconf 2.59 or later be installed, in order to compile Erlang/OTP. Erlang/OTP may have further requirements depending on your needs.
-Some packages may require additional libraries.</description>

-Overview As you can see on the diagram, the client begins by connecting to the server. This step is handled by a Ranch acceptor, which is a process dedicated to accepting new connections.
-After Ranch accepts a new connection, whether it is an HTTP/1.</description>

+      <description>Embedded mode allows you to insert Ranch listeners directly in your supervision tree. This allows for greater fault tolerance control by permitting the shutdown of a listener due to the failure of another part of the application and vice versa.
+However, just as for non-embedded listeners that were started via ranch:start_listener/5, it is required that the ranch application is running before you can start embedded listeners. Furthermore, this also means that embedded listeners will restart when ranch_sup fails.</description>

However, you may want to stop a listener in a graceful fashion, ie by not accepting any new connections, but allowing the existing connection processes to exit by themselves instead of being killed.
+For this purpose, you should first suspend the listener you wish to stop gracefully, and then wait for its connection count to drop to zero.</description>

-      <description>Escripts are an alternative to release. They are meant to be used for small command line executables written in Erlang.
-They are not self-contained, unlike releases. Erlang must be installed for them to run. This however means that they are fairly small compared to releases.
-For self-contained executables, check self-extracting releases.
-Requirements Erlang.mk uses p7zip by default to generate the escript archive. Make sure it is installed. On most systems the package is named p7zip; on Ubuntu you need p7zip-full.</description>

+      <description>Ranch 2.0 adds support for multiple connection supervisors.
+Ranch 1.x had a bottleneck because it used only a single connection supervisor. This was more evident when many connections were dropped at once as the supervisor couldn&amp;apos;t keep up and failed to accept new connections while cleaning up the old ones. Ranch 2.0 behaves much better in this scenario by default. Multiple connection supervisors also helps with concurrently accepting new connections.</description>

-      <description>Cowboy delegates the request processing to middleware components. By default, two middlewares are defined, for the routing and handling of the request, as is detailed in most of this guide.
-Middlewares give you complete control over how requests are to be processed. You can add your own middlewares to the mix or completely change the chain of middlewares as needed.
-Cowboy will execute all middlewares in the given order, unless one of them decides to stop processing.</description>

-      <description>Why would you choose Erlang.mk, if not for its many features? This chapter will attempt to answer that.
-Erlang.mk is fast Erlang.mk is as fast as it gets.
-Erlang.mk will group the compilation of files so as to avoid running the BEAM more than necessary. This saves many seconds compared to traditional Makefiles, even on small projects.
-Erlang.mk will not try to be too smart. It provides a simple solution that works for most people, and gives additional options for projects that run into edge cases, often in the form of extra variables or rules to be defined.</description>

-      <description>This chapter aims to be a brief record of the life of the Erlang.mk project.
-Before Erlang.mk Erlang.mk originates from the Cowboy project. Cowboy started as a Rebar project and I, Loïc Hoguin, was very happy with it for a couple years. Over time however I started getting annoyed and frustrated by a number of things, including bad defaults, changing defaults and overall slowness.
-In particular, at the time I gave up on Rebar, the Cowboy test suite was taking about five minutes to run.</description>

+We are getting very close to releasing Ranch 2.0! As most of the tremendous programming work was done by contributor Jan Uhlig, I will yield the floor and let him describe what went into this great release.
+In Ranch 1.x, there is only one supervisor per Ranch listener to start and manage connection processes. Under high load (many clients rapidly connecting and/or disconnecting), the message queue of this one supervisor could becomes congested, leading to declining accept rates or a stalled listener.</description>

-      <description>Name cowboy_handler - Plain HTTP handlers
-Description The cowboy_handler middleware executes the handler selected by the router or any other preceding middleware.
-This middleware takes the handler module and initial state from the handler and handler_opts environment values, respectively. On completion, it adds a result value to the middleware environment, containing the return value of the terminate/3 callback (if defined) and ok otherwise.
-This module also defines a callback interface for handling HTTP requests.</description>
