Hi, I recently updated my python UF product to use Zope's built in Sessions instead of CST. Now I am faced with two problems: 1. How to completely expire all session stuff on logout. At this point of time I am using the following terminate session function to do so: def __terminate_session (Self,REQUEST): REQUEST.SESSION.invalidate() REQUEST.SESSION.getBrowserIdManager().flushBrowserIdCookie() so the question is : Is this enough?? or do I have to something more?? 2. How can I call my UF's user_logout function on expiry of the session?? In CST there was a field that allowed me to set up a method to be called on expiry. I didnt find any such option in the session_data_manager or browser_id_manager. So how do I do that?? TIA AM
