can users also go forward again?
Because those pages will be gone then it is a stack.
I would just monitor which pages goes out of the stack at what time.
in 1.3 with the new SecondLevelCache this wouldn't happen at all. All pages
can be found again.

Hi
We are experiencing some PageExpired exceptions, where I believe they
should not occur.
We are running on a clustered environment, two tomcats with apache infront
as loadbalancer.
As I see it pageExpired could happen if somehow apache sent the user to
the wrong server(we are using the session affinity JK-mod I belive so that
should not happen). Else pageExpired would happen if the users session
expire or the user tries to reach a page that's pop'ed from the pagemap
stack (I belive our limit are 15).
Could pageExpired also come if the user gets an exception?
And finally we are also seeing that if a user double posts their form they
get an pageExpired message, how can I prevent this?
We are using the pagemap to retrieve previous pages, so that the user can
press a previous button… And as I remember it we are clearing our pagemap
when we begin a new flow(its also on this page that we experience the page
expired if double post occur, im not sure how this interferes with the
request cycle).
Lets say user clicks twice(then two page rendering are waiting), and
somewhere in the code we clear the page map what happens then?
