In this article I will explain how to disable browser back
button after logout in asp.net using JavaScript. Normally when we press back
button it will redirected to previous page. So to avoid this we have to disable
the browser back button.
Javascript
Code for Disable Browser Back Button:
<script type
= "text/javascript"
>
function preventBack() { window.history.forward();
}
setTimeout("preventBack()",
0);
window.onunload = function () { null };
</script>
