I'm not an expert on web servers, but I would think that when you invalidate
a session, all session properties would also become invalid.

If you want to check a session property, can you do that before invalidating
the session?

I agree with John F. Once you invalidate a session all bets are off. You need to fetch the values before session invalidation.
