No. This will not work in a clustered environment. However, what Mark
suggested is the simplest approach and should hold good in a normal ( not
clustered) webapp. If you want to achieve this is a clustered environment,
you will have to maintain a table, possibly in a Database, of user-ids and
possibly session-ids, login time. Before you autenticate the user as a part
of the login, you should check for the existance of the user-id in the table
and then proceed.
Ofcourse, this introduces other complexities like cleaning up your table on
shutdown, cleaning up expired session-ids from the table etc

Will this work, if the application is running in a cluster?
