That's correct Steve. I the server side, the socket is set to {active, false} in the beginning.

But when HTTP headers parsing is done, I change it to {active, true} by calling:
ok = inet:setopts(Socket, [{active, true}, 
                               {packet, raw}, 
                               {delay_send, true},
                               {keepalive, true}]),
