title: In ASP.NET, when should I use Session.Clear() rather than Session.Abandon()?
body: <p>Both Session.Clear() and Session.Abandon() get rid of session variables.  As I understand it, Abandon() ends the current session, and causes a new session to be created thus causing the End and Start events to fire.</p>
  
  <p>It seems preferable to call Abandon() in most cases, such as logging a user out.  Are there scenarios where I'd use Clear() instead?  Is there much of a performance difference?</p>
