Ready for another theory? Hold onto your hats for this one... If you're
using Apache Tomcat v5.X, you might try something like this:
The Tomcat context files allow a context to specify a session persistence

The theory is to override the PersistentManager with your own class.
Theirs subclasses the PersistentManagerBase which subclasses ManagerBase.
Now inside ManagerBase it seems to create the sessions in the method
createSession(String). If you override that, you could count the sessions
