What previous data you want to clear? Do you want to restrict previous page with back button?

i found the solution to 'disable BACK button:

<script type="text/javascript">
window.history.forward();
function noBack(){ window.history.forward(); }
</script>
</head>
<body onLoad="noBack();" onpageshow="if (event.persisted) noBack();" onUnload="">

the problem is, when i clicked on 'log out' link, it will redirect user to index.html.
then, i clicked 'back' button, it will go back to previous page where, member area, some php code make looks ugly..

'undefined bla bla bla on line bla bla bla', which mean i already unset all data

is the solution of disabled the 'back' button is good?

The best is to session expire the page rather than trying those JS tricks.

im sorry, above code is not working, btw above code is to disabled right click of the mouse so, user cannot copy using 'right-click', and view the source code.

here is the right code:

[COLOR="DarkGreen"]

<script>
var isNS = (navigator.appName == "Netscape") ? 1 : 0;
if(navigator.appName == "Netscape") document.captureEvents(Event.MOUSEDOWN||Event.MOUS EUP);
function mischandler(){
return false;
}
function mousehandler(e){
var myevent = (isNS) ? e : event;
var eventbutton = (isNS) ? myevent.which : myevent.button;
if((eventbutton==2)||(eventbutton==3)) return false;
}
document.oncontextmenu = mischandler;
document.onmousedown = mousehandler;
document.onmouseup = mousehandler;
</script>
