Question

how to check if a particular session is alive through its ID?

Asked by: Abdu_Allah

Many single sign on systems can check whether a particular session is alive
if it's passed a sessionID via web service. How is this done in .NET if the
service app uses InProc session? I can't seem to find anything in the .NET
class library that exposes the session collections in an application.
However the infrastructure to lookup a session based on the sessionID(which I save every sessions ID in DB) is definite in ASP.NET. Does anyone have any suggestions?

I know I can change to use database to track ASP.NET sessions, and then can
query against the DB to find out whether a particular one is still alive.
It would be my last resort if the InProc mode doesn't work out.

In other words I'm looking for a function like this: IsAlive(sessionID)
Thanks

http://aspalliance.com/520_Detecting_ASPNET_Session_Timeouts.2

this is an example of detecting session timeout. You can use this (and edit it) to know whether the CURRENT session is alive or timed out. You can also know if a session is new or existing. From all that you can add to your database the id of the new session when it is new, and remove it when it times out. Also note that for this approach to be practical you need to make your aspx pages inherit from a custom BaseClass that you create (which in turn inherits from Page).

Did you read the questio arefully?! I'm not talking about the current session, my question is about any particular session that I have its own id.

questio arefully = question carefully

 

by: Infinite_RecursionPosted on 2008-08-01 at 08:06:33ID: 22138997

Yes I read the question carefully, and that is why I was saying you need to save EVERY NEW Session and remove EVERY TIMED OUT Session, so you can do a query on the DB on the sessionID that you want.
