Given the current version of my game, the answer would be no. The only thing I need for now is to know who has won at the end. This may change later on though. I have seen that Ehcache can be integrated in GAE<http://ehcache.org/documentation/googleappengine.html>, but as far as I know it doesn't provide any hook to plug a listener in before the removal occurs.
Anyway, thanks for your answer :) -- Sébastien Tromp 2011/7/26 J.Ganesan <j.gane...@datastoregwt.com> > I had this kind of issue when I wanted to maintain an object cache.
