Gotta pick that issue up. Been looking at a combination of pound and
msessions for my next biggie, wondering if there's any collective wisdom
on this list that I could gain insight from.

Make sure you redirect them and pass the original page's location as a
parameter - I did this for one customer, and they were counting on their
browser 'remembering' their login information... But this doesn't work
if you login from a different URL every time! I thought I was being
shifty, but in effect was making them crazy.

Use the timestamp stored with the session - I've never seen anyone hit
the 'logout' button, ever.

Bingo. The question I have is where are you storing the session data?
What kind of performance requirements do you have?
