I am using the built in asp.net membership, etc... and using the login control. How do I make the login timeout 30 minutes, so they don't have to login for 30 minutes AFTER INACTIVITY.
IMPORTANT: I have to make sure ALL SESSION VARIABLES are stored for this amount of time as well. Why? I jump from my site to authorize.net so they can input their cc info, etc... then after they are done they are RETURNED to my site and several of the session vars are accessed for further processing. I need all of this to not timeout!
