+::: cowboy_req
+
+The `cowboy_req` module provides functions to access, manipulate
+and respond to requests.
+
+The functions in this module follow patterns for their return types,
+based on the kind of function.
+
+* access: `{Value, Req}`
+* action: `{Result, Req} | {Result, Value, Req} | {error, atom()}`
+* modification: `Req`
+* question: `boolean()`
+
+The only exception is the `chunk/2` function which may return `ok`.
+
+Whenever `Req` 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.
+
+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.
+
+It is highly discouraged to pass the Req object to another process.
+Doing so and calling `cowboy_req` functions from it leads to
+undefined behavior.
+
+:: Types
+
+: body_opts() = [{continue, boolean()}

+
+: req() - opaque to the user

+* Range = {non_neg_integer(), non_neg_integer() | infinity} | neg_integer()
+
+The cookie names and values, the values of the sec-websocket-protocol
+and x-forwarded-for headers, the values in `AcceptExt` and `Params`,
+the authorization `Credentials`, the `ExpectValue` and `OpaqueTag`
+are case sensitive. All values in `ContentTypeParams` 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.
+
+The headers accept, accept-encoding and cookie headers can return
+an empty list. Others will return `{error, badarg}` if the header
+value is empty.
+
+The authorization header parsing code currently only supports basic
+HTTP authentication. The `Credentials` type is thus `{Username, Password}`
+with `Username` and `Password` being `binary()`.
+
+The range header value `Range` can take three forms:
+
+* `{From, To}`: from `From` to `To` units
+* `{From, infinity}`: everything after `From` units
+* `-Final`: the final `Final` units

+* Data = binary()
+* Reason = atom()
+
+Read the request body.
+
+This function will read a chunk of the request body. If there is
+more data to be read after this function call, then a `more` tuple
+is returned. Otherwise an `ok` tuple is returned.
+
+Cowboy will automatically send a `100 Continue` reply if
+required. If this behavior is not desirable, it can be disabled
+by setting the `continue` option to `false`.
+
+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 `length`, `read_length`
+and `read_timeout` 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.
+
+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 `content_decode` and `transfer_decode`
+options allow setting the decode functions manually.
+
+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.
+
+This function can only be called once. Cowboy will not cache
+the result of this call.
+
+: body_length(Req) -> {Length, Req2}
+
+Types:
+
+* Length = non_neg_integer() | undefined
+
+Return the length of the request body.
+
+The length will only be returned if the request does not
+use any transfer-encoding and if the content-length header
+is present.

+
+Return the request body as a list of tuples.
+
+This function will parse the body assuming the content-type
+application/x-www-form-urlencoded, commonly used for the
+query string.
+
+This function calls `body/2` 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 `badlength` tuple is returned.
+
+This function can only be called once. Cowboy will not cache

+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.
+
+The headers returned are MIME headers, NOT HTTP headers.
+They can be parsed using the functions from the `cow_multipart`
+module. In addition, the `cow_multipart:form_data/1` function
+can be used to quickly figure out `multipart/form-data` messages.

+This function calls `body/2` for reading the body, with the
+same options it received. It uses the same defaults.
+
+If there are more data to be read from the socket for this
+part, the function will return what it could read inside a
+`more` tuple. Otherwise, it will return an `ok` tuple.
+
+Calling this function again after receiving a `more` tuple
+will return another chunk of body. The last chunk will be
+returned inside an `ok` tuple.
+
+Note that once the body has been read, fully or partially,
+it cannot be read again.
+
+:: Response related exports
+
+: chunk(Data, Req) -> ok | {error, Reason}
+
+Types:
+
+* Data = iodata()
+* Reason = atom()
+
+Send a chunk of data.
+
+This function should be called as many times as needed
+to send data chunks after calling `chunked_reply/{2,3}`.
+
+When the method is HEAD, no data will actually be sent.
+
+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.
+
+: chunked_reply(StatusCode, Req) -> chunked_reply(StatusCode, [], Req)
+: chunked_reply(StatusCode, Headers, Req) -> {ok, Req2}
+
+Types:
+
+* StatusCode = cowboy:http_status()
+* Headers = cowboy:http_headers()
+
+Send a response using chunked transfer-encoding.
+
+This function effectively sends the response status line
+and headers to the client.
+
+This function will not send any body set previously. After
+this call the handler must use the `chunk/2` function
+repeatedly to send the body in as many chunks as needed.
+
+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.
+
+This function can only be called once, with the exception
+of overriding the response in the `onresponse` hook.
+
+: continue(Req) -> ok | {error, Reason}
+
+Types:
+
+* Reason = atom()
+
+Send a 100 Continue intermediate reply.
+
+This reply is required before the client starts sending the
+body when the request contains the `expect` header with the
+`100-continue` value.
+
+Cowboy will send this automatically when required. However
+you may want to do it manually by disabling this behavior
+with the `continue` body option and then calling this
+function.
+
+: delete_resp_header(Name, Req) -> Req2
+
+Types:
+
+* Name = binary()
+
+Delete the given response header.
+
+While header names are case insensitive, this function expects
+the name to be a lowercase binary.
+
+: has_resp_body(Req) -> boolean()
+
+Return whether a response body has been set.
+
+This function will return false if a response body has
+been set with a length of 0.
+
+: has_resp_header(Name, Req) -> boolean()
+
+Types:
+
+* Name = binary()
+
+Return whether the given response header has been set.

+: reply(StatusCode, Headers, Body, Req) -> {ok, Req2}
+
+Types:
+
+* StatusCode = cowboy:http_status()
+* Headers = cowboy:http_headers()
+* Body = iodata()
+
+Send a response.
+
+This function effectively sends the response status line,
+headers and body to the client, in a single send function
+call.
+
+The `reply/2` and `reply/3` functions will send the body
+set previously, if any. The `reply/4` function overrides
+any body set previously and sends `Body` instead.
+
+If a body function was set, and `reply/2` or `reply/3` was
+used, it will be called before returning.
+
+No more data can be sent to the client after this function
+returns.
+
+This function can only be called once, with the exception
+of overriding the response in the `onresponse` hook.
+
+: set_resp_body(Body, Req) -> Req2
+
+Types:
+
+* Body = iodata()
+
+Set a response body.
+
+This body will not be sent if `chunked_reply/{2,3}` or
+`reply/4` is used, as they override it.

+: set_resp_body_fun(Fun, Req) -> Req2
+: set_resp_body_fun(Length, Fun, Req) -> Req2
+
+Types:
+
+* Fun = fun((Socket, Transport) -> ok)
+* Socket = inet:socket()
+* Transport = module()
+* Length = non_neg_integer()
+
+Set a fun for sending the response body.
+
+If a `Length` 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.
+
+This function will only be called if the response is sent
+using the `reply/2` or `reply/3` function.
+
+The fun will receive the Ranch `Socket` and `Transport` as
+arguments. Only send and sendfile operations are supported.
+
+: set_resp_body_fun(chunked, Fun, Req) -> Req2
+
+Types:
+
+* Fun = fun((ChunkFun) -> ok)
+* ChunkFun = fun((iodata()) -> ok | {error, atom()})
+
+Set a fun for sending the response body using chunked transfer-encoding.
+
+This function will only be called if the response is sent
+using the `reply/2` or `reply/3` function.
+
+The fun will receive another fun as argument. This fun is to
+be used to send chunks in a similar way to the `chunk/2` function,
+except the fun only takes one argument, the data to be sent in
+the chunk.
+
+: set_resp_cookie(Name, Value, Opts, Req) -> Req2
+
+Types:
+
+* Name = iodata()
+* Value = iodata()
+* Opts = cookie_opts()
+
+Set a cookie in the response.
+
+Cookie names are case sensitive.
+
+: set_resp_header(Name, Value, Req) -> Req2
+
+Types:
+
+* Name = binary()
+* Value = iodata()
+
+Set a response header.
+
+You should use `set_resp_cookie/4` instead of this function
+to set cookies.
+
+:: Misc. exports
+
+: compact(Req) -> Req2
+
+Remove any non-essential data from the Req object.
+
+Long-lived connections usually only need to manipulate the
+Req object at initialization. Compacting allows saving up
+memory by discarding extraneous information.

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

------
-

-
-> HTTP headers as a list of key/values.
-
-### http_status() = non_neg_integer() | binary()
-
-> HTTP status.
->
-> A binary status can be used to set a custom message.
-
-### http_version() = 'HTTP/1.1' | 'HTTP/1.0'
-
-> HTTP version.
-
-### onrequest_fun() = fun((cowboy_req:req()) -> cowboy_req:req())
-
-> Fun called immediately after receiving a request.
->
-> It can perform any operation on the `Req` object, including
-> reading the request body or replying. If a reply is sent,
-> the processing of the request ends here, before any middleware
-> is executed.
-
-### onresponse_fun() = fun((http_status(), http_headers(),
-	iodata(), cowboy_req:req()) -> cowboy_req:req())
-
-> Fun called immediately before sending the response.
->
-> It can perform any operation on the `Req` object, including
-> reading the request body or replying. If a reply is sent, it
-> overrides the reply initially sent. The callback will not be
-> called again for the new reply.
-
-Exports
--------
-
-### start_http(Ref, NbAcceptors, TransOpts, ProtoOpts) -> {ok, pid()}
-
-> Types:
->  *  Ref = ranch:ref()
->  *  NbAcceptors = non_neg_integer()
->  *  TransOpts = ranch_tcp:opts()
->  *  ProtoOpts = cowboy_protocol:opts()
->
-> Start listening for HTTP connections. Returns the pid for this

-
-### stop_listener(Ref) -> ok | {error, not_found}
-
-> Types:
->  *  Ref = ranch:ref()
->
-> Stop a previously started listener.
-
-### set_env(Ref, Name, Value) -> ok
-
-> Types:
->  *  Ref = ranch:ref()
->  *  Name = atom()
->  *  Value = any()
->
-> Set or update an environment value for an already running listener.
-> This will take effect on all subsequent connections.

-> that haven't been executed yet. The connection may be left
-> open to receive more requests from the client.
->
-> The `error` return value sends an error response identified
-> by the `StatusCode` and then proceeds to terminate the
-> connection. Middlewares that haven't been executed yet
-> will not be called.

-cowboy_req
-==========
-
-The `cowboy_req` module provides functions to access, manipulate
-and respond to requests.
-
-The functions in this module follow patterns for their return types,
-based on the kind of function.
-
- *  access: `{Value, Req}`
- *  action: `{Result, Req} | {Result, Value, Req} | {error, atom()}`
- *  modification: `Req`
- *  question: `boolean()`
-
-The only exception is the `chunk/2` function which may return `ok`.
-
-Whenever `Req` 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.
-
-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.
-
-It is highly discouraged to pass the Req object to another process.
-Doing so and calling `cowboy_req` functions from it leads to
-undefined behavior.
-
-Types
------
-
-### 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()}]
-
-> Request body reading options.
-
-### cookie_opts() = [{max_age, non_neg_integer()}
-	| {domain, binary()} | {path, binary()}
-	| {secure, boolean()} | {http_only, boolean()}]
-
-> Cookie options.
-
-### req() - opaque to the user
-
-> The `Req` object.
->
-> All functions in this module receive a `Req` as argument,
-> and most of them return a new object labelled `Req2` in
-> the function descriptions below.

->
-> The headers accept, accept-encoding and cookie headers can return
-> an empty list. Others will return `{error, badarg}` if the header
-> value is empty.
->
-> The authorization header parsing code currently only supports basic
-> HTTP authentication. The `Credentials` type is thus `{Username, Password}`
-> with `Username` and `Password` being `binary()`.

-> The range header value `Range` can take three forms:
->  *  `{From, To}`: from `From` to `To` units
->  *  `{From, infinity}`: everything after `From` units

-### qs(Req) -> {QueryString, Req2}
-
-> Types:
->  *  QueryString = binary()
->
-> Return the request's query string.

-Request body related exports
-----------------------------
-
-### body(Req) -> body(Req, [])
-### body(Req, Opts) -> {ok, Data, Req2} | {more, Data, Req2} | {error, Reason}
-
-> Types:
->  *  Opts = [body_opt()]
->  *  Data = binary()
->  *  Reason = atom()
->
-> Read the request body.
->
-> This function will read a chunk of the request body. If there is
-> more data to be read after this function call, then a `more` tuple
-> is returned. Otherwise an `ok` tuple is returned.
->
-> Cowboy will automatically send a `100 Continue` reply if
-> required. If this behavior is not desirable, it can be disabled
-> by setting the `continue` option to `false`.
->
-> 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 `length`, `read_length`
-> and `read_timeout` 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.
->
-> 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 `content_decode` and `transfer_decode`
-> options allow setting the decode functions manually.
->
-> 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.
->
-> This function can only be called once. Cowboy will not cache
-> the result of this call.
-
-### body_length(Req) -> {Length, Req2}
-
-> Types:
->  *  Length = non_neg_integer() | undefined
->
-> Return the length of the request body.
->
-> The length will only be returned if the request does not
-> use any transfer-encoding and if the content-length header
-> is present.
-
-### body_qs(Req) -> body_qs(Req,
-	[{length, 64000}, {read_length, 64000}, {read_timeout, 5000}])
-### body_qs(Req, Opts) -> {ok, [{Name, Value}], Req2}

-
-> Types:
->  *  Opts = [body_opt()]
->  *  Name = binary()
->  *  Value = binary() | true
->  *  Reason = chunked | badlength | atom()
->
-> Return the request body as a list of tuples.
->
-> This function will parse the body assuming the content-type
-> application/x-www-form-urlencoded, commonly used for the
-> query string.
->
-> This function calls `body/2` 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 `badlength` tuple is returned.
->
-> This function can only be called once. Cowboy will not cache
-> the result of this call.
-
-### has_body(Req) -> boolean()
-
-> Return whether the request has a body.
-
-### part(Req) -> part(Req,
-	[{length, 64000}, {read_length, 64000}, {read_timeout, 5000}])
-### part(Req, Opts) -> {ok, Headers, Req2} | {done, Req2}
-
-> Types:
->  *  Opts = [body_opt()]
->  *  Headers = cow_multipart:headers()
->
-> Read the headers for the next part of the multipart message.
->
-> 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.
->
-> The headers returned are MIME headers, NOT HTTP headers.
-> They can be parsed using the functions from the `cow_multipart`
-> module. In addition, the `cow_multipart:form_data/1` function
-> can be used to quickly figure out `multipart/form-data` messages.
-> It takes the list of headers and returns whether this part is
-> a simple form field or a file being uploaded.
->
-> Note that once a part has been read, or skipped, it cannot
-> be read again.
->
-> This function calls `body/2` 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.
-
-### part_body(Req) -> part_body(Req, [])
-### part_body(Req, Opts) -> {ok, Data, Req2} | {more, Data, Req2}
-
-> Types:
->  *  Opts = [body_opt()]
->  *  Data = binary()
->
-> Read the body of the current part of the multipart message.
->
-> This function calls `body/2` for reading the body, with the
-> same options it received. It uses the same defaults.
->
-> If there are more data to be read from the socket for this
-> part, the function will return what it could read inside a
-> `more` tuple. Otherwise, it will return an `ok` tuple.
->
-> Calling this function again after receiving a `more` tuple
-> will return another chunk of body. The last chunk will be
-> returned inside an `ok` tuple.
->
-> Note that once the body has been read, fully or partially,
-> it cannot be read again.

-Response related exports
-------------------------
-
-### chunk(Data, Req) -> ok | {error, Reason}
-
-> Types:
->  *  Data = iodata()
->  *  Reason = atom()
->
-> Send a chunk of data.
->
-> This function should be called as many times as needed
-> to send data chunks after calling `chunked_reply/{2,3}`.
->
-> When the method is HEAD, no data will actually be sent.
->
-> If the request uses HTTP/1.0, the data is sent directly

-> compatibility with older clients.
-
-### chunked_reply(StatusCode, Req) -> chunked_reply(StatusCode, [], Req)
-### chunked_reply(StatusCode, Headers, Req) -> {ok, Req2}
-
-> Types:
->  *  StatusCode = cowboy:http_status()
->  *  Headers = cowboy:http_headers()
->
-> Send a response using chunked transfer-encoding.
->
-> This function effectively sends the response status line
-> and headers to the client.
->
-> This function will not send any body set previously. After
-> this call the handler must use the `chunk/2` function
-> repeatedly to send the body in as many chunks as needed.
->
-> 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.
->
-> This function can only be called once, with the exception
-> of overriding the response in the `onresponse` hook.
-
-### continue(Req) -> ok | {error, Reason}
-
-> Types:
->  *  Reason = atom()
->
-> Send a 100 Continue intermediate reply.
->
-> This reply is required before the client starts sending the
-> body when the request contains the `expect` header with the
-> `100-continue` value.
->
-> Cowboy will send this automatically when required. However
-> you may want to do it manually by disabling this behavior
-> with the `continue` body option and then calling this
-> function.
-
-### delete_resp_header(Name, Req) -> Req2
-
-> Types:
->  *  Name = binary()
->
-> Delete the given response header.
->
-> While header names are case insensitive, this function expects

-
-### has_resp_body(Req) -> boolean()
-
-> Return whether a response body has been set.
->
-> This function will return false if a response body has

-
-### has_resp_header(Name, Req) -> boolean()
-
-> Types:
->  *  Name = binary()

-
-> Types:
->  *  StatusCode = cowboy:http_status()
->  *  Headers = cowboy:http_headers()
->  *  Body = iodata()
->
-> Send a response.
->
-> This function effectively sends the response status line,

-> call.
->
-> The `reply/2` and `reply/3` functions will send the body
-> set previously, if any. The `reply/4` function overrides

->
-> If a body function was set, and `reply/2` or `reply/3` was
-> used, it will be called before returning.

-cowboy_rest
-===========
-
-The `cowboy_rest` module implements REST semantics on top of
-the HTTP protocol.
-
-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.
-
-The only mandatory callback is `init/3`, needed to perform
-the protocol upgrade.
-
-Types
------
-
-None.
-
-Meta values
------------
-
-### charset
-
-> Type: binary()
->
-> Negotiated charset.
->
-> This value may not be defined if no charset was negotiated.
-
-### language
-
-> Type: binary()
->
-> Negotiated language.
->
-> This value may not be defined if no language was negotiated.
-
-### media_type
-
-> Type: {binary(), binary(), '*' | [{binary(), binary()}]}
->
-> Negotiated media-type.
->
-> The media-type is the content-type, excluding the charset.
->
-> This value is always defined after the call to
-> `content_types_provided/2`.
-
-Callbacks
----------
-
-### init({TransportName, ProtocolName}, Req, Opts)
-	-> {upgrade, protocol, cowboy_rest}
-	| {upgrade, protocol, cowboy_rest, Req, Opts}
-
-> Types:
->  *  TransportName = tcp | ssl | atom()
->  *  ProtocolName = http | atom()
->  *  Req = cowboy_req:req()
->  *  Opts = any()
->
-> Upgrade the protocol to `cowboy_rest`.
->
-> This is the only mandatory callback.
-
-### rest_init(Req, Opts) -> {ok, Req, State}
-
-> Types:
->  *  Req = cowboy_req:req()
->  *  Opts = any()
->  *  State = any()

-
-### rest_terminate(Req, State) -> ok
-
-> Types:
->  *  Req = cowboy_req:req()
->  *  State = any()
->
-> Perform any necessary cleanup of the state.
->
-> 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.
-
-### Callback(Req, State) -> {Value, Req, State} | {halt, Req, State}
-
-> Types:
->  *  Callback - one of the REST callbacks described below
->  *  Req = cowboy_req:req()
->  *  State = any()
->  *  Value - see the REST callbacks description below
->
-> Please see the REST callbacks description below for details
-> on the `Value` 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.
->
-> The `halt` tuple can be returned to stop REST processing.
-> It is up to the resource code to send a reply before that,
-> otherwise a `204 No Content` will be sent.
-
-REST callbacks description
---------------------------
-
-### allowed_methods
-
->  *  Methods: all
->  *  Value type: [binary()]
->  *  Default value: [<<"GET">>, <<"HEAD">>, <<"OPTIONS">>]
->
-> Return the list of allowed methods.
->
-> Methods are case sensitive. Standard methods are always uppercase.
-
-### allow_missing_post
-
->  *  Methods: POST
->  *  Value type: boolean()
->  *  Default value: true
->
-> Return whether POST is allowed when the resource doesn't exist.
->
-> Returning `true` here means that a new resource will be
-> created. The URL to the created resource should also be
-> returned from the `AcceptResource` callback.
-
-### charsets_provided
-
->  *  Methods: GET, HEAD, POST, PUT, PATCH, DELETE
->  *  Value type: [binary()]
->  *  Skip to the next step if undefined
->
-> Return the list of charsets the resource provides.
->
-> The list must be ordered in order of preference.
->
-> 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.
->
-> The chosen charset will be set in the `Req` object as the meta
-> value `charset`.
->
-> While charsets are case insensitive, this callback is expected
-> to return them as lowercase binary.
-
-### content_types_accepted
-
->  *  Methods: POST, PUT, PATCH
->  *  No default
->
-> Types:
->  *  Value = [{binary() | {Type, SubType, Params}, AcceptResource}]
->  *  Type = SubType = binary()
->  *  Params = '*' | [{binary(), binary()}]
->  *  AcceptResource = atom()
->
-> Return the list of content-types the resource accepts.
->
-> The list must be ordered in order of preference.
->
-> Each content-type can be given either as a binary string or as
-> a tuple containing the type, subtype and parameters.
->
-> 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 `'*'`. If the parameters value is set to `[]`
-> only content-type values with no parameters will be accepted. All
-> parameter values are treated in a case sensitive manner except the
-> `charset` parameter, if present, which is case insensitive.
->
-> 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 `cowboy_req:method/1` and return a
-> different list for each methods.
->
-> The `AcceptResource` value is the name of the callback that will
-> be called if the content-type matches. It is defined as follow.
->
->  *  Value type: true | {true, URL} | false
->  *  No default
->
-> Process the request body.
->
-> 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.
->
-> If the request body was processed successfully, `true` or
-> `{true, URL}` may be returned. If an URL is provided, the
-> response will redirect the client to the location of the
-> resource.
->
-> If a response body must be sent, the appropriate media-type, charset
-> and language can be retrieved using the `cowboy_req:meta/{2,3}`
-> functions. The respective keys are `media_type`, `charset`
-> and `language`. The body can be set using `cowboy_req:set_resp_body/2`.
-
-### content_types_provided

->
-> Return the list of content-types the resource provides.
->
-> The list must be ordered in order of preference.
->
-> Each content-type can be given either as a binary string or as

-> If any parameter is acceptable, then the tuple form should be used
-> with parameters set to `'*'`. If the parameters value is set to `[]`
-> only content-type values with no parameters will be accepted. All
-> parameter values are treated in a case sensitive manner except the
-> `charset` parameter, if present, which is case insensitive.
->
-> The `ProvideResource` 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.
->
->  *  Methods: GET, HEAD
->  *  Value type: iodata() | {stream, Fun} | {stream, Len, Fun} | {chunked, ChunkedFun}
->  *  No default
->
-> Return the response body.
->
-> The response body may be provided directly or through a fun.
-> If a fun tuple is returned, the appropriate `set_resp_body_fun`
-> function will be called. Please refer to the documentation for
-> these functions for more information about the types.
->
-> The call to this callback happens a good time after the call to
-> `content_types_provided/2`, when it is time to start rendering
-> the response body.
-
-### delete_completed
-
->  *  Methods: DELETE
->  *  Value type: boolean()
->  *  Default value: true
->
-> Return whether the delete action has been completed.
->
-> This function should return `false` if there is no guarantee
-> that the resource gets deleted immediately from the system,
-> including from any internal cache.
->
-> When this function returns `false`, a `202 Accepted`

-
-### delete_resource
-
->  *  Methods: DELETE
->  *  Value type: boolean()
->  *  Default value: false
->

->  *  Methods: GET, HEAD
->  *  Value type: calendar:datetime() | binary() | undefined
->  *  Default value: undefined
->

-
-### forbidden
-
->  *  Methods: all
->  *  Value type: boolean()
->  *  Default value: false
->
-> Return whether access to the resource is forbidden.
->
-> A `403 Forbidden` response will be sent if this
-> function returns `true`. This status code means that
-> access is forbidden regardless of authentication,
-> and that the request shouldn't be repeated.
-
-### generate_etag
-
->  *  Methods: GET, HEAD, POST, PUT, PATCH, DELETE
->  *  Value type: binary() | {weak | strong, binary()}
->  *  Default value: undefined
->
-> Return the entity tag of the resource.
->
-> This value will be sent as the value of the etag header.
->
-> 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.
-
-### is_authorized
-
->  *  Methods: all
->  *  Value type: true | {false, AuthHeader}
->  *  Default value: true
->
-> Return whether the user is authorized to perform the action.
->
-> This function should be used to perform any necessary
-> authentication of the user before attempting to perform
-> any action on the resource.

-> Return whether the put action results in a conflict.
->
-> A `409 Conflict` response will be sent if this function
-> returns `true`.
-
-### known_content_type
-
->  *  Methods: all
->  *  Value type: boolean()
->  *  Default value: true
->
-> Return whether the content-type is known.
->
-> This function determines if the server understands the
-> content-type, regardless of its use by the resource.
-
-### known_methods
-

->  *  Value type: [binary()]
->  *  Default value: [<<"GET">>, <<"HEAD">>, <<"POST">>, <<"PUT">>, <<"PATCH">>, <<"DELETE">>, <<"OPTIONS">>]
->
-> Return the list of known methods.
->
-> The full list of methods known by the server should be
-> returned, regardless of their use in the resource.
->
-> The default value lists the methods Cowboy knows and
-> implement in `cowboy_rest`.
->
-> Methods are case sensitive. Standard methods are always uppercase.
-
-### languages_provided
-
->  *  Methods: GET, HEAD, POST, PUT, PATCH, DELETE
->  *  Value type: [binary()]
->  *  Skip to the next step if undefined
->
-> Return the list of languages the resource provides.
->
-> The list must be ordered in order of preference.
->
-> 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.
->
-> The chosen language will be set in the `Req` object as the meta
-> value `language`.
->
-> While languages are case insensitive, this callback is expected
-> to return them as lowercase binary.
-
-### last_modified
-
->  *  Methods: GET, HEAD, POST, PUT, PATCH, DELETE
->  *  Value type: calendar:datetime()
->  *  Default value: undefined
->
-> Return the date of last modification of the resource.
->
-> 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.
-
-### malformed_request
-
->  *  Methods: all
->  *  Value type: boolean()
->  *  Default value: false
->
-> Return whether the request is malformed.
->
-> Cowboy has already performed all the necessary checks
-> by the time this function is called, so few resources
-> are expected to implement it.
->
-> The check is to be done on the request itself, not on
-> the request body, which is processed later.
-
-### moved_permanently
-
->  *  Methods: GET, HEAD, POST, PUT, PATCH, DELETE
->  *  Value type: {true, URL} | false
->  *  Default value: false
->
-> Return whether the resource was permanently moved.
->
-> If it was, its new URL is also returned and sent in the
-> location header in the response.

-
-### multiple_choices
-
->  *  Methods: GET, HEAD, POST, PUT, PATCH, DELETE
->  *  Value type: boolean()
->  *  Default value: false
->
-> Return whether there are multiple representations of the resource.
->
-> 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 `true`,
-> the response body should include information about these
-> different representations using `cowboy_req:set_resp_body/2`.
-> The content-type of the response should be the one previously
-> negociated and that can be obtained by calling
-> `cowboy_req:meta(media_type, Req)`.
-
-### options
-
->  *  Methods: OPTIONS
->  *  Value type: ok
->  *  Default value: ok
->
-> Handle a request for information.
->
-> The response should inform the client the communication
-> options available for this resource.
->
-> By default, Cowboy will send a `200 OK` response with the
-> allow header set.
-
-### previously_existed
-
->  *  Methods: GET, HEAD, POST, PATCH, DELETE

-> check if the resource previously existed first.
-
-### service_available
-
->  *  Methods: all
->  *  Value type: boolean()
->  *  Default value: true
->
-> Return whether the service is available.
->
-> This function can be used to test that all relevant backend

-> function returns `false`.
-
-### uri_too_long
-
->  *  Methods: all
->  *  Value type: boolean()
->  *  Default value: false
->
-> Return whether the requested URI is too long.
->
-> Cowboy has already performed all the necessary checks
-> by the time this function is called, so few resources
-> are expected to implement it.
->
-> A `414 Request-URI Too Long` response will be sent if this
-> function returns `true`.
-
-### valid_content_headers
-
->  *  Methods: all
->  *  Value type: boolean()
->  *  Default value: true
->
-> Return whether the content-* headers are valid.
->
-> This also applies to the transfer-encoding header. This
-> function must return `false` for any unknown content-*
-> headers, or if the headers can't be understood. The
-> function `cowboy_req:parse_header/2` can be used to
-> quickly check the headers can be parsed.
->
-> A `501 Not Implemented` response will be sent if this

->  *  Value type: [binary()]
->  *  Default value: []
->
-> Return the list of headers that affect the representation of the resource.
->
-> These request headers return the same resource but with different
-> parameters, like another language or a different content-type.
->
-> Cowboy will automatically add the accept, accept-language and
-> accept-charset headers to the list if the respective functions
-> were defined in the resource.
->
-> This operation is performed right before the `resource_exists/2`
-> callback. All responses past that point will contain the vary
-> header which holds this list.

-cowboy_websocket_handler
-========================
-
-The `cowboy_websocket_handler` behaviour defines the interface used
-by Websocket handlers.
-
-The `init/3` and `websocket_init/3` callbacks will always be called,
-followed by zero or more calls to `websocket_handle/3` and
-`websocket_info/3`. The `websocket_terminate/3` will always
-be called last.
-
-Types
------
-
-None.
-
-Callbacks
----------
-
-### init({TransportName, ProtocolName}, Req, Opts)
-	-> {upgrade, protocol, cowboy_websocket}
-	| {upgrade, protocol, cowboy_websocket, Req, Opts}
-
-> Types:
->  *  TransportName = tcp | ssl | atom()
->  *  ProtocolName = http | atom()
->  *  Req = cowboy_req:req()
->  *  Opts = any()
->
-> Upgrade the protocol to `cowboy_websocket`.
-
-### websocket_init(TransportName, Req, Opts)
-	-> {ok, Req, State}
-	| {ok, Req, State, hibernate}
-	| {ok, Req, State, Timeout}
-	| {ok, Req, State, Timeout, hibernate}
-	| {shutdown, Req}
-
-> Types:
->  *  TransportName = tcp | ssl | atom()
->  *  Req = cowboy_req:req()
->  *  Opts = any()
->  *  State = any()
->  *  Timeout = timeout()
->
-> Initialize the state for this session.
->
-> 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.
->
-> The connection will stay up for a duration of up to `Timeout`
-> 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 `infinity`. 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.
->
-> The `hibernate` option will hibernate the process until it
-> starts receiving either data from the Websocket connection
-> or Erlang messages.
->
-> The `shutdown` return value can be used to close the connection
-> before upgrading to Websocket.
-
-### 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}
-
-> Types:
->  *  InFrame = {text | binary | ping | pong, binary()}
->  *  Req = cowboy_req:req()
->  *  State = any()
->  *  OutFrame = cowboy_websocket:frame()
->
-> Handle the data received from the Websocket connection.
->
-> This function will be called every time data is received
-> from the Websocket connection.
->
-> The `shutdown` return value can be used to close the
-> connection. A close reply will also result in the connection
-> being closed.
->
-> The `hibernate` option will hibernate the process until
-> it receives new data from the Websocket connection or an
-> Erlang message.
-
-### 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}
-
-> Types:
->  *  Info = any()
->  *  Req = cowboy_req:req()
->  *  State = any()
->  *  OutFrame = cowboy_websocket:frame()
->
-> Handle the Erlang message received.
->
-> This function will be called every time an Erlang message
-> has been received. The message can be any Erlang term.
->
-> The `shutdown` return value can be used to close the
-> connection. A close reply will also result in the connection
-> being closed.
->
-> The `hibernate` option will hibernate the process until
-> it receives another message or new data from the Websocket
-> connection.
-
-### websocket_terminate(Reason, Req, State) -> ok
-
-> Types:
->  *  Reason = {normal, shutdown | timeout} | {remote, closed} | {remote, cowboy_websocket:close_code(), binary()} | {error, badencoding | badframe | closed | atom()}
->  *  Req = cowboy_req:req()
->  *  State = any()
->
-> Perform any necessary cleanup of the state.
->
-> The connection will be closed and the process stopped right
-> after this call.
