Hi Tom, hi Craig!
Another approach would be to extend the event model that is used for Session
(Servlet Spec SRV.10.1/SRV15.1.13) to fire events when a request is
completed..
Craig, would it be compliant with the spec to add another subclass of
SessionEvent (Maybe SessionRequestEvent)?
Then you could register your manager with newly created sessions as a
SessionListener.
