I have a application that runs fine on my development servers but as soon I put the application on the production servers I start losing my Session variables without the session expiring. I store the user ID in a session variable and keeps checking this variable until it no longer exist I redirect the user to the Login page. The problem is that the application returns the user to the login page in about 3-5 mins after login in sometimes even faster or slower. What I have notice is that it is not login off all the user at once it’s per user that the variables get lost. I have read the article about the Anti-virus touching my config files and my global asax, the anti-virus software I am using is MacAfee Virus- scan Enterprise. I have configured this to skip the above mentioned files but the problem still persists. I have tried using the State_server Mode but this didn’t solve the problem either.
