      <guid>https://ninenines.eu/docs/en/erlang.mk/1/guide/installation/</guid>
      <description>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.</description>

      <description>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.</description>

      <guid>https://ninenines.eu/docs/en/erlang.mk/1/guide/getting_started/</guid>
      <description>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.
 $ 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.</description>

      <guid>https://ninenines.eu/docs/en/ranch/1.2/guide/listeners/</guid>
      <description>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.</description>

      <guid>https://ninenines.eu/docs/en/gun/1.0/guide/start/</guid>
      <description>This chapter describes how to start and stop the Gun application.
 Setting up Specify Gun as a dependency to your application in your favorite build tool.
 With Erlang.mk this is done by adding gun to the DEPS variable in your Makefile.
 Adding Gun as an Erlang.mk dependency DEPS = gun   Starting Gun is an OTP application. It needs to be started before you can use it.</description>

      <guid>https://ninenines.eu/docs/en/gun/1.0/guide/protocols/</guid>
      <description>This chapter describes the protocols supported and the operations available to them.
 HTTP/1.1 HTTP/1.1 is a text request-response protocol. The client sends a request, the server sends back a response.
 Gun provides convenience functions for performing GET, HEAD, OPTIONS, POST, PATCH, PUT, and DELETE requests. All these functions are aliases of gun:request/4,5,6 for the respective methods. Gun also provides a gun:data/4 function for streaming the request body.
 Gun will send a gun_inform message for every intermediate informational responses received.</description>

      <description>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.</description>

      <description>Now that you know how to get started, let&amp;#8217;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 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>This chapter describes how to open, monitor and close a connection using the Gun client.
 Gun connections Gun is designed with the HTTP/2 and Websocket protocols in mind. They are built for long-running connections that allow concurrent exchange of data, either in the form of request/responses for HTTP/2 or in the form of messages for Websocket.
 A Gun connection is an Erlang process that manages a socket to a remote endpoint.</description>

      <description>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.</description>

      <description>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.</description>

      <guid>https://ninenines.eu/docs/en/erlang.mk/1/guide/updating/</guid>
      <description>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&amp;#8217;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.</description>

      <description>This chapter describes how to use the Gun client for communicating with an HTTP/1.1 or HTTP/2 server.
 Streams Every time a request is initiated, Gun creates a stream. A stream reference uniquely identifies a set of request and response and must be used to perform additional operations with a stream or to identify its messages.
 Stream references use the Erlang reference data type and are therefore unique.
 Streams can be canceled at any time.</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.
 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.</description>

      <description>No software is perfect.
 It&amp;#8217;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.</description>

      <description>This chapter describes how to use the Gun client for communicating with a Websocket server.
 HTTP upgrade Websocket is a protocol built on top of HTTP. To use Websocket, you must first request for the connection to be upgraded. Only HTTP/1.1 connections can be upgraded to Websocket, so you might need to restrict the protocol to HTTP/1.1 if you are planning to use Websocket over TLS.
 You must use the gun:ws_upgrade/2,3,4 function to upgrade to Websocket.</description>

      <guid>https://ninenines.eu/docs/en/ranch/1.2/guide/ssl_auth/</guid>
      <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>

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>

      <description>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.</description>

      <description>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&amp;#8217;s a match, the route&amp;#8217;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.</description>

      <description>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.
 C source code location and Erlang environment The C source code should be located in the $(C_SRC_DIR) directory.</description>

      <description>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}.</description>

      <description>Erlang.mk relies on Relx for generating releases. This chapter covers the Erlang.mk-specific bits. Consult the 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:
 RELX_CONFIG = $(CURDIR)/webchat.config Relx does not need to be installed. Erlang.mk will download and build it automatically.</description>

      <guid>https://ninenines.eu/docs/en/erlang.mk/1/guide/sfx/</guid>
      <description>Erlang.mk allows you to package 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:</description>

      <description>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 Req object and the initial state defined in the router configuration.
 A handler that does nothing would look like this:
 init(Req, State) -&amp;gt; {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.</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>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.</description>

      <description>Erlang.mk comes with integrated support for 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.</description>

      <description>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.</description>

      <guid>https://ninenines.eu/docs/en/erlang.mk/1/guide/compat/</guid>
      <description>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.</description>

      <description>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.</description>

      <description>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.</description>

      <description>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 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 EDoc manual.
 A common use for this variable is to enable Markdown in doc comments, using the edown application:</description>

      <description>Erlang.mk includes targets for running the 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 reST documents. There is a quick start guide on Sphinx&#39; website. For Erlang.mk, we&amp;#8217;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.</description>

      <description>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.</description>

      <description>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 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.</description>

      <guid>https://ninenines.eu/docs/en/cowboy/2.0/guide/multipart/</guid>
      <description>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.</description>

      <description>Common Test is Erlang&amp;#8217;s functional testing framework. Erlang.mk automates the discovery and running of Common Test suites.
 Writing tests The 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.</description>

      <description>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&amp;#8217;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 Roy T.</description>

      <description>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&amp;#8217;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.</description>

      <description>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 OTP version pinning section of the 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.</description>

 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 &#34;Start&#34; diagram, and all paths excluding the OPTIONS path go through the &#34;Content negotiation&#34;</description>

      <description>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.</description>

      <description>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.</description>

      <title>The Websocket protocol</title>

      <guid>https://ninenines.eu/docs/en/cowboy/2.0/guide/ws_protocol/</guid>
      <description>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).</description>

      <description>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.</description>

      <description>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.</description>

      <guid>https://ninenines.eu/docs/en/erlang.mk/1/guide/why/</guid>
      <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>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>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>

      <description>The following patch versions were released since Cowboy 2.2:
 Cowboy 2.2.2    While fixing the miscount in the previous patch release an issue was introduced where HTTP/2 bodies could be sent out of orders when using iolists. This has been corrected.     Cowboy 2.2.1    Colons are now allowed within path segments in routes provided to cowboy_router:compile/1 as long as they are not the first character of the path segment.</description>

      <description>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.</description>

      <guid>https://ninenines.eu/docs/en/cowboy/2.1/guide/migrating_from_2.0/</guid>
      <description>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.</description>

      <description>Cowboy 2.3 focused on making the Cowboy processes behave properly according to OTP principles. This version is a very good milestone toward that goal and most of everything should now work. Release upgrades and a few details will be improved in future versions.
 Features added    Add support for all functions from the module sys. Note that Cowboy currently does not implement the sys debugging mechanisms as tracing is recommended instead.</description>

      <description>Cowboy 2.4 focused on improving the HTTP/2 implementation. All existing tests from RFC7540 and the h2spec test suite now all pass. Numerous options have been added to control SETTINGS and related behavior. In addition experimental support for Websocket over HTTP/2 was added.
 Features added    Add experimental support for Websocket over HTTP/2. You can use the enable_connect_protocol option to enable. It implements the following draft: https://tools.ietf.org/html/draft-ietf-httpbis-h2-websockets-01    Add options max_decode_table_size and max_encode_table_size to restrict the size of the HPACK compression dictionary.</description>

      <description>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.</description>

      <description>Cowboy 2.2 focused on adding features required for writing gRPC servers and on completing test suites for the core HTTP RFCs, fixing many bugs along the way.
 Features added    Add support for sending trailers at the end of response bodies. Trailers are additional header fields that may be sent after the body to add more information to the response. Their usage is required in gRPC servers. They are optional and may be discarded in other scenarios (for example if the request goes through an HTTP/1.</description>

      <description>Cowboy 2.3 focused on making the Cowboy processes behave properly according to OTP principles. This version is a very good milestone toward that goal and most of everything should now work. Release upgrades and a few details will be improved in future versions.
 Features added    Add support for all functions from the module sys. Note that Cowboy currently does not implement the sys debugging mechanisms as tracing is recommended instead.</description>

 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.</description>

      <description>Name cowboy:set_env - Update a listener&amp;#8217;s environment value
   Description set_env(Name :: ranch:ref(), Key :: atom(), Value :: any()) -&amp;gt; ok Set or update an environment value for a previously started listener.
 This is most useful for updating the routes dynamically, without having to restart the listener.
 The new value will only be available to new connections. Pre-existing connections will still use the old value.
   Arguments  Name    The name of the listener to update.</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>

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

   Description cancel(ConnPid, StreamRef) -&amp;gt; ok ConnPid :: pid() StreamRef :: reference() Cancel the given stream.
 The behavior of this function depends on the protocol selected.
 HTTP/1.1 does not support this feature. Gun will simply silence the stream and stop relaying messages. Gun may also decide to close the connection if the response body is too large, to avoid wasting time and bandwidth.</description>

      <description>Name ranch - socket acceptor pool
   Description The ranch module provides functions for starting and manipulating Ranch listeners.
   Types max_conns() = non_neg_integer() | infinity Maximum number of connections allowed on this listener.
 This is a soft limit. The actual number of connections might be slightly above the limit due to concurrency when accepting new connections. Some connections may also be removed from this count explicitly by the user code.</description>

      <description>Name ranch - Socket acceptor pool for TCP protocols.
   Dependencies The ranch application has no particular dependency required to start.
 It has optional dependencies that are only required when listening for SSL connections. The dependencies are crypto, asn1, public_key and ssl. They are started automatically if they weren&amp;#8217;t before.
   Environment The ranch application defines one application environment configuration parameter.
  profile (false)    When enabled, Ranch will start eprof profiling automatically.</description>
