I used threads only to simulate delay in servlet preocessing. Other
than that it all happens in one thread inside the request.How do I
specify the timeout server close on disconnected requests, can I get
some notification in the code to break the loop in request? Would the
timeout affect connections while browser still waiting fro response
but no data is being sent?
Thanks,
Mike
