I too searched for it many times, but never got this, and frankly speaking there are no event/method meant for it. But yeah you can track if someone is trying to change the page and then stop him for doing so
e.g.

<body onunload="return checkpage()">

function checkpage()
{
 if (confirm('you are trying to surf outside this page\nsure?'))
 return true;

return false;
}

//Warning: Above function will also get execute even if you submit the page.

The other way is expire the ASP page immediately so that whenever it is accessed clicking on back button it is refreshed from web server.

for this use <meta tag> search syntax on web
or use expire property of asp.

Using expire property of ASP does not work. What is the proper place of using this property. I mean at the begining of page or end of page. I tried both but failed.

Try this, should work

<META HTTP-EQUIV="Pragma" CONTENT="no-cache">
<META HTTP-EQUIV="Expires" CONTENT="1981">
