I have problems with Session Time-out

Question

Hi,

 

I have problems with Session Time-out.

 

I need my Session to stay for more than an hour. For that, I have done the below things.

 

a) I have specified the timeout as 60 in the web.config of my application as below:
    <sessionState mode="InProc" stateConnectionString="tcpip=127.0.0.1:42424" sqlConnectionString="data source=127.0.0.1;Trusted_Connection=yes" cookieless="false" timeout="60" />

 

b) In IIS, web-site's configuration settings also I have changed to 60 minutes.

 

c) Though its not required, I have also changed the timeout to 60 in machine.config as below:

 

<sessionState mode="InProc" stateConnectionString="tcpip=127.0.0.1:42424" stateNetworkTimeout="10" sqlConnectionString="data source=127.0.0.1;Integrated Security=SSPI" cookieless="false" timeout="60"/>

 

Even though some times the session time-out is after 25 – 30 minutes and sometimes the session time-out was after more than 54 minutes.

 

Can any one give me any explanation for this unpredictable behaviour?

 

How to re-solve this type of situation. I dont want to change the sessionstate's mode other than In-proc.

 

Please help me in this regard.
