All,
What are strategies you've implemented to eliminate the "this page has 
expired" that commonly gets displayed after a user clicks the back button?
I've seen lots of sites that use sessions, where clicking the back 
button "breaks" the application by displaying the expired message.  I've 
seen a couple pages where clicking the back button doesn't break the 
application.
Hints, suggestions, thoughts?
Thanks,
Chris
