Since I replied to that post, I've read in other threads about the notion of using a Memcache based PageStore on GAE.
This may eliminate some of the issues I had with GAE/Wicket. I haven't had a chance to experiment since. Maybe someone else could comment if they've got production sites running with a non-HttpSessionStore and using the Memcache instead? That aside, what I said in the older thread still stands - HttpSessionStore = slow (due to speed of writes) and the serialization issues are still present. Essentially any HttpSession deserialization error will break the application for that user. This is made worse as Google still hasn't implemented any good way of cleaning up the _ah_session store. There's a servlet filter to do it, but it uses a lot of CPU and you may find the session table grows faster than you can clean it up. This isn't really much of a problem for apps that only store a few strings, etc. in HttpSession, so I guess that's why it's not seen as a priority.
