Richard,
Thanks for the quick reply.
Here is what I am trying to do :
I am trying to tunnel some http packets from the browser to a PC which
is inside a private network/firewall.
The PC in the pvt. netwok sends a request to my server at regular interval.
When the browser wants to send some packets to the PC (which it can't
without opening a port in the firewall), it sends the packets to my
program and my program tunnels those packets in the response to the
request messeges coming from the PC inside the firewall.
I am able to do it when there is only one PC and one browser tries to
access it by storing the socket ID of the browser connection in a
temporary variable in my program ,but I need some kind of mechanism
to store socket IDs for connections coming from multiple browsers.
Without which I can't distinguish between different connections.
Regards,
-Saswat
