I am using Forms Authentication in my ASP.NET 2.0 web app running on Windows Server 2003.
I am getting a steady flow of users complaining that they are being kicked out and asked to log in again after using the site for a short while.
I guess this is some idle time-out set somewhere but it's happening very quickly in some cases, after about 10 minutes.
This is obviously very frustrating for users when they are losing their progress on a form.
In my web.config I have the "timeout" attribute of <forms> within <authentication> set to 30 so this is not likely to be the issue. All of the users I have spoken to are sure they hadn't been using it for 30 minutes before they were kicked out.
What other variables could it be? Or is it possible it's a bug in my code? It's happened on a range of different pages within my application.
