ASP pages are "active server pages". If I'm not mistaken, they timeout after the session is lost. Their URL address constantly changes (hence "active" server). That might be why it comes up blank.
Were you sent this link by someone else? Is it a link on a website?
If you are the one initiating the "active" session with the webserver, then your browser shouldn't have a problem displaying the page since the URL address is current. However, if you're trying to get to an ASP page that was active say yesterday, then you'll be out of luck...
