Session_OnEnd not firing sometimes?

[Chris Ashley]

There seem to be isolated occurences of Session_OnEnd not firing in my
app. This is problematic because some clean up of resources happens
here. I know the Session events were unreliable in classic ASP, but is
this still the case in ASP.Net?

What kind of scenarios would case Session_OnEnd not to fire? Would
Application_Error being hit cause Session_OnEnd not to fire?

Hello Chris,

yep, it's still not relyable.
1) it works only for the InProc session management
2) With some SP (for VS or for Windows) it doesn't work at all - need hotfix

Hi michael,

Thanks for your response.

Is there any alternative? Maybe I could store some object in the
session and have its finalizer do the clear up? Would this work, so
when it is garbage collected (presumably at some point after there is
no reference to it in Session scope), my clean up will happen because
GC will call it's finalizer?

Hello Chris,

You can use Application and Cache instead

read the MSDN to get more info about this

I think the Session timeout can be set on the server,
