I am designing a Client Server Chat application in Java which uses TCP connection between them. I am not able to figure out how to detect at server side when a client forcefully closes down. I need this as i am maintaining a list of online clients and i need to remove user from the list when he forcefully closes the connection.
Any help will be highly appreciated.
Thanks
Tara Singh
One way to receive timely notification of a disconnect is to attempt to send a small piece of information at regular intervals. Then, the latest that you’ll know of a client disconnect is at most your interval. People call this a heartbeat.
