That depends on the rest of the server. E.g., what does http_accept do? Does it 
get called at all? Does it set the recv callback on the connection pcb?

Oh, and setting the recv callback to the listening pcb is wrong. It might even 
lead to accessing invalid memory, maybe that's your problem? You should try to 
move the tcp_recv call into http_accept.
