Cowboy is also a socket acceptor pool, able to accept connections for any kind of tcp protocol.

cowboy aims to provide the following advantages:

* 'small' code base.
* damn 'fast'.
* 'modular': transport and protocol handlers are replaceable.
* 'binary http' for greater speed and lower memory usage.
* easy to 'embed' inside another application.
* selectively 'dispatch' requests to handlers, allowing you to send some
requests to your embedded code and others to a fastcgi application in
php or ruby.
* no parameterized module. no process dictionary. 'clean' erlang code.
