I'm sure a lot of you have seen this warning when hitting your Back buttin in IE. Says Page Expired, hit refresh to resend the information. Here at my work, on our POS site, our users can normally hit the back button and go to the last page, and the txt fields would have the data they entered previously. After about a month, they start getting this warning. We use Xp pro, ie6sp1. Most people say that it is the web page code that causes this, but strangly enough, if I delete the users profiles, and re-logon, they can hit the back button again with no problems (for about a month!!!). Does anyone know why this happens at random times? If it starts out working with a fresh profile, why does it not work after time passes? I am just getting tired of re-creating profiles, moving documents etc... to keep my users happy. Any information would be appriciated ;)
Thanks
