ASP.NET Session and Form Authentication Timeout
I do not want to keep logging into my own routine ASP.NET sites over and over again.
I needed to increase a timeout.
First I added new attribute to web.config file
<forms name=\"AUTH\" loginUrl=\"~/Login.aspx\"
cookieless=\"AutoDetect\" timeout=\"40000\" />
I used IIS Admin to set a new value for the site Session State – Cookie Settings – Time-out to the same high number of minutes
Every 10000 minutes correspond to about a week time. Maximum value is one year, i.e. 60*24*365 = 525,600 minutes.
