just recently I noticed a change after login for a secured web site.
If I do not explicitly sign out from the secured web site my login remains valid on the server. The web site has the signout button implemented.

The situation was always that when I left IE completely on my local machine my login was somehow terminated.

I am not sure if it is my local machine or the server that caused this behavior. Therefore my question is:

How do I control that a login is terminated after so many minutes idle state of the user or when a user leaves the IE environment.

The dev guide App. A Web Config parameters does not say too much about the caching.

Pls hint me to the appropriate section in the guide or other advice is appreciated.
tks, -Eric.
