+cowboy_loop - loop handlers
+
+== Description
+
+The `cowboy_loop` module implements a handler interface for
+long running HTTP connections. It is the recommended interface
+for long polling and server-sent events, amongst others.
+
+This module is a sub protocol that defines three callbacks to
+be implemented by handlers. The `init/2` and `terminate/3`
+callbacks are common to all handler types and are documented
+in the manual for the link:cowboy_handler.asciidoc[cowboy_handler] module.
+
+The `info/3` callback is specific to loop handlers and will be
+called as many times as necessary until a reply is sent.
+
+It is highly recommended to return a timeout value from the
+`init/2` callback to ensure that the process is terminated
+when no data has been received during that timespan. The
+default timeout is `infinity`, which should only be used if
+you have alternate means of ending inactive connections.
+
+== Terminate reasons
+
+The following values may be received as the terminate reason
+in the optional `terminate/3` callback.
+
+normal::
+ The connection was closed normally before switching to the
+ loop sub protocol. This typically happens if an `ok` tuple is
+ returned from the `init/2` callback.
+
+stop::
+ The handler requested to close the connection by returning
+ a `stop` tuple.
+
+timeout::
+ The connection has been closed due to inactivity. The timeout
+ value can be configured from `init/2`. The response sent when
+ this happens is a `204 No Content`.
+
+{crash, Class, Reason}::
+ A crash occurred in the handler. `Class` and `Reason` can be
+ used to obtain more information about the crash. The function
+ `erlang:get_stacktrace/0` can also be called to obtain the
+ stacktrace of the process when the crash occurred.
+
+{error, overflow}::
+ The connection is being closed and the process terminated
+ because the buffer Cowboy uses to keep data sent by the
+ client has reached its maximum. The buffer size can be
+ configured through the environment value `loop_max_buffer`
+ and defaults to 5000 bytes.
+ +
+ If the long running request comes with a body it is recommended
+ to process this body before switching to the loop sub protocol.
+
+{error, closed}::
+ The socket has been closed brutally without a close frame being
+ received first.
+
