What happens when a session expires?

What does asp.net do in the background when a session expires? Is the session completely disposed of, or do I need to add something like Session.Abandon(); in my Session_End event in Global.asax?

In-memory state - the object is removed from list of sessions and Session_End is called. For SQL session state nothing happens and data will no longer be returned for future requests with the same session ID since it does not match (ID + non-expired) condition.

You don't need to call Session.Abandon() in Session_End because that event called when session is expired (which is exactly what Abandon does).

Notes

  • normal web applications that use out-of-process session state (SQL on state service) will not receive Session_End event because out-ouf-process state does not fire it.
  • if you need to cleanup SQL session state you can run clenaup task that deletes rows for expired sessions.

Session will get cleared if you were using inproc session provider so you won't need to call Session.Abandon().

The session is completely disposed. You don't need to do anything special. Session_End is an event that allows you to do things upon session disposal.

Session.Abandon() is a command that lets you terminate a session at will.

Note: If you don't put any variable in the Session, then Session_End will not fire.
