<P>Now that we've seen how to create servers, let's spend just a moment
making a client. Since this is so easy, I'm going to do all of it in this
one page.

<P>
Kirthika says, "Here's an one paragraph abstract for a one page client app:"
X
<UL>
X The server is an Stream object of ACE_SOCK_Stream type. The
X ACE_Sock_Connector does the job of actively making a connection with the
X listening server. It does so using the server_host_address and port
X number which are stored in the ACE_INET_Addr object.Once the
X connection has been established, the client begins its interaction
X with the server and bombards it with messages.
X Note: send_n() call is used since this call sees to the issues of
X network buffering and reliably gets the data across to the server.
X Also, a timeout value is set to provide fault tolerance if the server
X ever dies before the transaction is completed. The server calls a
X close() method
X once it reads in zero bytes during the Event_Handler::handle_input()
X call. This
X proves that the client has severed its connection. The server then
X shuts down.

<P>Ok, so that was pretty easy. What would be even easier would be to wrap
all of the connection mess up in an object and overload a couple of basic
operators to make things less network-centric. Perhaps we'll see that in
another tutorial.
