hi
i have a problem
see when we connect to any web server then according to http protocol
we connect on port 80 so when we connect to server on port 80 it
means that a socket is created on server which binds the port 80 with
let say to a client A Now the communication will be done by this
socket ( now this port will not used by any other socket) so when any
other client B will try to connect with the same server how it will
connect i mean the port is already occupied by this socket.
may be it is a stupid question but please answer this so that i can
clear the situation more
see what i am doing is i have created a server which is listening on
port 10000 now whenever a client tries to connect it it gets connected

(opens a socket) so now when any other client B trying to
connect on same port so is possible that server again get connected to

client B on this same socket ?????

A TCP connection is identified by four pieces of information: local
address, local port, remote address, and remote port. You can have
multiple connections with the same local address and port (port 80), but
they'll each have different remote address and/or remote port, so they
won't conflict with each other.

Run "netstat" on your server while multiple clients are connect and
you'll see all the different connections, each with different values in
the remote columns.
