How to stop frequent Session Time outs in your Deployed website in IIS.

The Project which i am working had got a very strange problem that it is facing frequent Session timeout at my client machine.And Everybody treats that increase of the Session time in the Webconfig file can solve our problem.But that did n't solved our problem.What are the steps that i had taken to solve this problem i need to discuss here.

Step:1I open my Internet information services VERSION 7.0 in my Computer.and select a dummy project in the IIS 7.0 in the right pane i saw a sessionstate icon i selected and double Click here there are so many radio button for selection one is not enable two is In process three is Custom and fourth one is session state server.In my project i am using inprocess mode so it is default selected and TimeOut is 20 minutes by default.Now i changed to 20 Minutes to 120 Minutes.And click apply.It acknowledges me Saved information successfully.See the Below Image.



Now i observe my Webconfig file it is Updated like this.



Now i need to set the idle time out for my Website.For that i select Application pools which is there at the top of the Internet information services.On the Extreme right pane I have SetApplicationPooldefaults Which is a Link and i click that a Poppup with some properties had visible.I carefully observe is there any property that i can set for idle Timeout
yes its there now i set the property for that.It is by default 20 minutes i changed to 120.

see the below image



Now i sent a mail regarding these things to change for those People who are working on the Client Computer.They have done all those now they are not facing any session time outs problem.I am very happy that i rectified this problem.
