Yes, but there isn't much difference: as long as httpready sees 
something different from a HTTP request, it just passes the 
connection to nginx.

Quoting accf_http(9):

     If something other than a HTTP/1.0 or HTTP/1.1 HEAD or GET request is
     received the kernel will allow the application to receive the connection
     descriptor via accept().

So the only difference is an additional check in the kernel.
