Author: admin | Posted: 13-06-2010 | Category: ASP.NET(vb.net) & Session Variables

ASP.NET(vb.net) Session.Abandon() - Session Object - Session.Abandon() : The 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.
