One way to deal with this would be to create a JavaBean that implements
HttpSessionBindingListener, and have your "log in" logic add this bean to the
user's session. When the bean's valueBound() method is called, it can register
itself in some shared collection of currently logged in users (perhaps in a
servlet context attribute), and can remove itself when valueUnbound() is
called.
