[thelist] Disabling Back Button with Alert

I need to disable the back button within a portion of an intranet web
application (to avoid losing session variables). I know the
js to do this but I'd also like to pop up an alert to let the user know
why the back button is disabled. The following doesn't work:
<script>
function goforward() {
if(window.history.forward(1) != null)
alert('We disabled the back button, blah, blah');
history.forward();
}
</script>
<body onLoad="goforward()">
It seems that once the browser receives the history.forward()
instruction, it ignores all else. Is there a way to do this with js?
The app is coded in CFML so perhaps there's a technique using that
language as well.
(And yes, I know disabling the back button is "bad" but it's being used
in a limited area).
Thanks.
