I don't know if that's a lot. This depends on your setup. In my development image I have 3403 instances, on www.lukas-renggli.ch I have 13021 instances. Whenever a page is rendered a context is created for every possible navigation path (every link). That could be optimized of course, but never was a problem so far. These contexts should quickly go away, if they are not needed anymore. Furthermore, then are a couple of contexts (default is 1024) stored in PRHistoryPersistency (if you are using this strategy). So if you reset the history and clean the session cache, you should not have any PRContext instances anymore. Lukas -- Lukas Renggli http://www.lukas-renggli.ch
