I am having a problem with one of our internal web sites. A user can login into two different businesses on our web site and see their data. The issue we are having is that when a customer logs into the first business looks at their data and then logs out if they then try and login to the other business they are seeing their old data until they click refresh. We can not duplicate this problem on our development server and the code is exactly the same. Somehow the session variables are not being refreshed until the page is reloaded. Could this be an IIS issue? Any suggestions would be great.
