@ -229,6 +229,11 @@ After initializing your protocol, it is recommended to wait to receive a message
containing the atom 'shoot', as it will ensure Cowboy has been able to fully
initialize the socket. Anything you do past this point is up to you!
If you need to change some socket options, like enabling raw mode for example,
you can call the <em>Transport:setopts/2</em> function. It is the protocol's
responsability to manage the socket usage, there should be no need for an user
to specify that kind of options while starting a listener.
You should definitely look at the cowboy_http_protocol module for a great
example of fast request handling if you need to. Otherwise it's probably
safe to use `{active, once}` mode and handle everything as it comes.
