Session problems...

I just added sessions to a web site that I am developing, and now the browser keeps saying "page expired" when I hit back on several pages. For example, I have a search page that displays results, user clicks on a result to view, and when the user hits back to go back to the search list they get the page expired message and must refresh. How can I keep this from happening? I am displaying user information in a header file that gets loaded with each page, so I have to use sessions for each page. This didn't happen before I added the session code. Thanks. -- Dana Holt / danah@home.com -- http://www.theydidmewrong.com/ http://www.shedidmewrong.com/ http://www.hedidmewrong.com/ --
