The project I work on uses Wicket 1.3.4 and we are using the default session store (SecondLevelCacheSessionStore.)
The app is clustered and runs on WebLogic 8 through Apache. I'm not entirely sure how those two are setup but I don't believe there is any resource sharing between instances in a cluster. Instead, when a session is started, a WebLogic instance is chosen and all future requests in that session are sent to that one instance. Using that setup, there shouldn't be any issues with a user's request going to a machine that doesn't have their page map. The problem is happening during normal "forward" use. The example that I was given was a user taking a few minutes to fill out some information and by the time they submit the form, their session appears to have timed out and they get a page expired error. I hope that helps to clarify things a bit.
