I have several links on a website that go to different crystal reports. When I log in, click on a link to a report and use the back button go back to the main page the first time, I don't have any trouble. But the second time I lose my username session variable. Is this a common problem? It seems like if it works the first time it would work subsequent times as well but obviously I am doing something wrong.

This is the code I'm using to check for the session variable on my main page.
<%if Session("user") = "username" then%>

Like I said it works on login and on the first back button action but then it won't work. Any thoughts?

Two things.

First, check the session.expires property. It should be 20 minutes but perhaps it is set for a shorter period.

Secondly, and more likely, switch your logic...<%If Session("user")<>""%> Perhaps it is 'losing' the value of "username" and returning a boolean false thereby not executing the remaining code.

Let me know if this helps

Great suggestion. I hadn't thought of it. But unfortunately it didn't work. The expires property is set at 90 which should be more than enough. The part that gets me is it works the first time, but then quits working. Any other ideas?

Someone suggested I open the reports in a new window to avoid losing my session variable. A little messy but it works. Still open to suggestions but I've solved the immediate problem. Thank you for your help.
