This is a wrong approach. APS.NET application does not have access to a Browser and should not attempt it. If this is possible for some Browser using a client-side script, some other Browser does not have to follow this rule.

Rather, the Web site status model should be tolerant to any user's navigation. In worse case, the page is considered in the invalid state, so some controls on the page are disabled. Not so about the controls of the Browser itself — the Web application never touchs them and never assumes anything about them. This is how decent authentication-based sites work.

Very good reference and Sandeep's work, my 5. It shows that I was not quite right as controlling cache is a legitimate way.
