I did some testing on this some time ago and with the standard tomcat filter the behavior is fairly intuitive. If I use the BaseContext.bindThreadObjectContext() method, then the Cayenne filter creates and returns a DataContext for each user session. If the session goes out of scope or times-out, the it appears the DataContext does as well (because I get a new DataContext at that point). This seems like reasonable behavior for most implementations. I suppose you could configure so that you get a new DataContext for each new request (but that may not be the most optimum design). Joe
