I have an aspx page that redirects to another page to display a chart drawn on the fly. I pass data to the chart page using querystring. All works fine until I click on the Back button.<BR><BR>When I click back to go back to the main page, I get a "Page Expired" error page and instructed to "refresh".<BR><BR>The same pages work fine (both directions) if I don't use querystring but instead cache the data or put it in session variables.<BR><BR>Is this normal IE behavior when using querystring?<BR><BR>Tom T
