preventing use of back button on web pgs

preventing use of back button on web pgs

A real techy geeks question!

I know that you can disable the back button with use of javascript etc. But what I want to do is ensure that the "Page expired" error comes up if someone presses the back button. Anyone know how to do this?

I dont think its totally possible to disable the back button.

You could force the previous page to go forward again..

Code:

<script language="JavaScript"><!--
javascript:window.history.forward(1);
//--></script>

or I found this method, which replaces the location of the page...but wont work with all browsers.

Code:

<script language="JavaScript"><!--
if (document.images)
    location.replace('http://www.somewhere.com/apage.html');
else
    location.href = 'apage.html';
//--></script>

This one looks pretty promising. It could sort the problem cheers
