The following code fragment was the original code for this page, and as far as I can tell, it just doesn't work:

To: "aspbrowserheck" <[email protected]>
Subject: [aspbrowserheck] RE: back button

We had that same requirement, what we came up with was a rather simple idea.
Each page that we want refreshed we simply add " history.go(1);" in a
function fired by the onload event.
