[ace-users] ACE_Reactor question

[Mihai Bucica]

Ok.It's my fault because I didn't detailed enough the
problem.

The HTTP server must deal with one client at a time.
While I'm serving one client I don't want the Acceptor
to handle new connections by creating new
service-handling object(RequestResponse_Handler
objects  in my case).

I have
class RequestResponse_Handler : public
ACE_Svc_Handler<ACE_SOCK_STREAM, ACE_MT_SYNCH> { ..}

1)This means that when a client connects
RequestResponse_Handler::open() is called
2) When I receive the query string
RequestResponse_Handler::handle_input() is called and
the request is passed to thread #2 to do the hard
work.
3)At one moment in future thread #2 ends its work and
puts the response in the sync queue of
service-handling object with
RequestResponse_Handler::putq(mb)
4)After that ::handle_output() & handle_close() is
called.


ONLY NOW(after step 4) I want the Acceptor to serve
the next (buffered) TCP connection request by creating
a new service-handling object(RequestResponse_Handler)


Thanks,
Valentin
