+::: cowboy_http_handler
+
+The `cowboy_http_handler` behaviour defines the interface used
+by plain HTTP handlers.
+
+Unless noted otherwise, the callbacks will be executed sequentially.
+
+:: Types
+
+None.
+
+:: Callbacks
+
+: init({TransportName, ProtocolName}, Req, Opts)
+ -> {ok, Req, State} | {shutdown, Req, State}
+
+Types:
+
+* TransportName = tcp | ssl | atom()
+* ProtocolName = http | atom()
+* Req = cowboy_req:req()
+* Opts = any()
+* State = any()
+
+Initialize the state for this request.
+
+The `shutdown` return value can be used to skip the `handle/2`
+call entirely.
+
+: handle(Req, State) -> {ok, Req, State}
+
+Types:
+
+* Req = cowboy_req:req()
+* State = any()
+
+Handle the request.
+
+This callback is where the request is handled and a response
+should be sent. If a response is not sent, Cowboy will send
+a `204 No Content` response automatically.
+
+: terminate(Reason, Req, State) -> ok
+
+Types:
+
+* Reason = {normal, shutdown} | {error, atom()}
+* 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. Typical plain HTTP handlers rarely need to
+use it.
