Session Timeout Problem After Migrating to .net 3.5

Asked by: stuyguy

We have migrated a .Net 1.1 applicatoin to .Net 3.5 and are getting very short session timeouts (10 to 20 minutes) even though we have timeout=1000 in the web.config.  Any ideas?

can you post the code where you are setting timeout, can you also post the error/message you get once timeout expires?

Here is the line from the web.config:

<SESSIONSTATE timeout="1000" cookieless="false" sqlConnectionString="data source=127.0.0.1;Trusted_Connection=yes" stateConnectionString="tcpip=127.0.0.1:42424" mode="InProc" /><sessionState mode="InProc" stateConnectionString="tcpip=127.0.0.1:42424" sqlConnectionString="data source=127.0.0.1;Trusted_Connection=yes" cookieless="false" timeout="1000"/>

There is no error message because each page in the application detects if there are certain session variables present. If the session variables are not present the application redirects to the login page.  The application is redirecting to the login page after 10 minutes of non-use.

One possible explaination is that you are using .Net Server 2003 and your IIS Application Pool is configured to recycle the worker process after 10 minutes. When the asp worker process is recycled, the session state is dropped and the user is forced to log in again.

Thanks.

 

by: stuyguyPosted on 2008-07-24 at 17:32:14ID: 22085035

That appears to have resolved the problem.  Thank you.

BTW, Any reason not to set the worker process timeout to a very high value.  We have a web application with about 30 users a day per web server.  We need to keep the session alive for as long as possible.
