This implementation is specific to JRun. It is not in the servlet API, so you
cannot count on using it anywhere else.
A portable way to deal with "session start" and "session end" events is to define
a user object that implements HttpSessionBindingListener, and store this object in
the user session when the session is established (i.e. when the user first logs
on). The valueBound() method of this object will be called then, which is
effectively a "session start" notification. The valueUnbound() method of this
object will be called when the session is invalidated or times out, which gives
you a "session end" notification.
