Forms Authentication timeout default in ASP.NET 2.0

Found a good article on ScottGu's blog about setting the timeout value for Forms Authentication.

One thing I want to add to this is that I learned that in addition to modifying the web.config, you also need to adjust the Application Pool in IIS. The Application Pool has an 'Idle timeout' setting where it will shutdown the worker process after a certain number of minutes being idle.

Here's another good link: http://forums.asp.net/p/989129/1281199.aspx.
