Hello, I have an website build in .net 3.5 and C#, with session timeout set to 60 minutes
But, when hosted within an web farm, the session expires invariably in 20 minutes.

<sessionState mode="InProc" timeout="60" cookieless="false" cookieName="training" regenerateExpiredSessionId="true">
		</sessionState>

Open in new window


I have tried also with mode="StateServer", as stated here , same result.

What should I do more to keep session alive for 60 minutes?

Thanks,
Daniel

Hi,

You may need to change mode from InProc to SQLServer.

can you check whether the timeout has been set to 60 minute in the website's application pool settings?

have a look on the below link to check the idle timeout value

http://bradkingsley.com/iis7-application-pool-idle-time-out-settings/

<sessionState mode="InProc" 
        timeout="60" 
        cookieless="false" 
        cookieName="training" 
        regenerateExpiredSessionId="true">
</sessionState>

Open in new window

I am not able to see and /or modify the application pool, since this feature is reserved to hosting company.

They said the followings are set, after asking: "what is the default value for application pool recycling (in Mb and / or minutes)?":

 
Private Memory Limit : 200 MB
Regular Time Interval : 60 min
Virtual Memory Limit : unlimited

I'm still awaiting for a response from them regarding using SqlServer session mode.
But, in case the SqlServer session mode is not an option, what else should I do?

Thanks
