this is not going to work if the client is behind a firewall,
because the servlet will not have the IP of the client.

THe only way I know of is to make the servlet poll the client at regular
interval to see if it is still alive!
Create a thread that keeps a live connection to the application client in
your servlet and let it poll your client at regular intervalls. When you
don't get a reply you know the client is down.
Keep in mind that this will have a seriouse impact on your ressources when
you have a lot of connections.
Or you can just have one thread running that polls all clients.
Hope that helps
Stefan
