Just wondering if someone could give me some direction as to the scalability of using detached objects. If a large object is kept in the http session and subsequently used by another transaction this saves me the trouble of having to do the additional select for that object before I modify it. My only concern is if the system has alot users ... the session data would seem to build up very quicky on the server cause of say the thousands of users working with these detached objects ?
