You can retrieve the current user's "session id" from the
HttpSessionBindingEvent e using "e.getSession().getId()". Use this value to
look up an entry in your hastable and remove it.
The HttpSessionBindingEvent is generated when the session is invalidated
(valueUnbound()) or created (valueBound()).
For more details read the Java doc on HttpSessionBindingEvent. Make sure
your class maintaining the hashtable implements the
javax.servlet.http.HttpSessionBindingListener interface.
