Session will be interfered by another application's thread

[JimWu]

Hi, I have a problem about session and application.

The situation describes as follows.

I have two web site A and B. They have different AppDomain.

First of all, I use session to record some info. in A.

While I invoke the application method "Applicaion.Rem oveAll()" inside a thread, the session of web site A will be expired.
So web site A could not access to any value of session.

But if web site B do not use thread to invoke this thread, the session of web site B would not be affected.

I dont know why it cause session expire. So far as I know, since A and B is different AppDomain, why session would be interfered by another application using the thread.

Thanks any kindly answer.

Jim.

Sounds like a question for an IIS expert...

There is a lot of imprecision here. If there is a child/parent relationship, eg virtual domain, it may have this effect. They may share the same application pool. Seems to me you have discovered a relationship and now you need to discover what it is. HTH.

I think they are have application pools.

If my illustratation is wrong, please correct my opinion.

A and B is different web application and they use different AppDomain.

Then, there is different virtual domain for them, eg., A is "http://10.2.2.55/A/index.aspx" and B is "http://10.2.2.55/B/Clear.aspx".

While web site A performs first in the browser, the state of session is alive.

But while I performs web site B using thread to clear state value of the application in another browser, the state value of session in A would be also cleaned.

I havnt figured out this problem so far.

I do not know either my concept wrong or having solution to solve this problem.

If someone knows, thanks for your kindly answer.

Jim.
