What happens to session value after it expires?

Question

I just want to know what will happen to the session after it reach it timeout.

I went through the question about “What happens to cart object when session expires?” but it doesn’t explain much.

Does it completely remove the session object or making it null?

Thanks

@leppie: I believe on Windows Servers it would be RecycleBin :) but dev/null is a classic deadend anyway — sll, Dec 06 '11 at 10:46
@leppie, oh no! I believe all session variables go to Heaven — Yuriy Rozhovetskiy, Dec 06 '11 at 10:48
Don't listen to them @Yuriy! - they *do* go to session heaven — Neil Thompson, Dec 06 '11 at 10:53
Isn't there a stack exchange site for such existential questions? What happens to any of us when we reach our timeout? — Simon Halsey, Dec 06 '11 at 12:44

When the session timeout occurs the Session_End event in global.asax is raised (except when session is handled by the DB) and the session collection is cleared. (the items are removed) If no other object is holding a reference to a particular object in the session collection the GC will collect it.

In general, only the session state will be removed. i.e. all items that had been stored in the Session will be discarded. However, it depends upon the session-state modes (MSDN article). In some cases the session object might be null (read SO thread).
