HTTPSessions: sessionDestroyed(), attributeRemoved(), etc

[Dion Almaer <di...@almaer.com>]

Hi guys -

I am trying to write some code that listens to HTTPSessions, and when the server is going to destroy
it, I want to do something with it first.  sessionDestroyed() seems to be called AFTER the session is destroyed,
and as soon as one attribute is removed due to invalidation, the session can't be accessed (IllegalStateException is thrown saying
that the session is already invalidated).

What is the best way to do this?  Would it be better to have a Map where I add objects, and add that Map to the session,
and then have the Map implement HttpSessionBindingListener.valueUnbound() and get the attributes that way?

Cheers,

Dion
