You certainly don't want to set the timeout to infinite. You'll keep piling up resources and the server will eventually roll over and die.

I would not recommend setting the timeout higher at all. the session timer resets each time there is a postback, so timing out means the user didn't touch the application in over 20 minutes.

There are several things you can do:

1.
set the time out to a larger value. You can do this in IIS directly per application it's a real b... to navigate IIS so you'll need to search a bit.

2. You can reset the timer when it expires by using the events in the global.asax file.

3. You can do a postback via scripting each xx minutes.

4. (recommended) You can set a script timer to let's say 15 minutes and inform the user with a message like "careful, your session is about to expire in 5 minutes, please do x or y to continue the session."

I would not do 1, 2 or 3.

hope this helps.
