问题
I have an application which stores session variables. When I do the logout I call the RemoveAll() method on available sessions.
The method seems not working. Do you know how it is possible to force removing a Session variable?
Regards.
回答1:
Session.Abandon()
cancels the current session
Session.Clear()
will just clear the session data and the the session will remain alive
more Details:
Session.Abandon() method destroys all the objects stored in a Session object and releases their resources. If you do not call the Abandon method explicitly, the server destroys these objects when the session times out(I may add:Session_OnEnd event is triggered)

Session.Clear() just removes all values (content) from the Object. The session with the same key is still alive.
