I have a webpage where i have some core page links in the master page. When I click them, I pass a query string to the default.aspx page to change how the page is rendered.
So as an example, the page looks like this:
<asp:ImageButton ID="foo" NavigateUrl="~/default.aspx" ... />
<asp:ImageButton ID="foo" NavigateUrl="~/default.aspx?2" ... />
<asp:ImageButton ID="foo" NavigateUrl="~/default.aspx?3" ... />
You get the idea. The problem is that whenever i go to any of these other pages, and hit refresh on them, I get the "web page expired" box. Any ideas how to avoid this?
