Since all request are coming from the same browser instance (even if different
windows), there is only one session as far as the servlet knows. There's no way
around that. Of course, using two different browsers would keep the sessions distinct
(i.e., user opens IE, then opens Netscape).
The thing I would suggest is to store a flag or something in the session immediately
after a user has logged in. Then send an error back on any request that tries to log
in while this flag is true. That should prevent multiple concurrent users.
