Put this between your <head> and </head> tags.

<script>
<!--
if (history.length > 0) {
  history.go(+1);
}
//-->

</script>

also if you are loading the page yourself (from a link or something) then instead of having a normal link or using window.location.href = "http://wahatever.com/page.htm" use window.location.replace("Http://www.whatever.com/page.htm") and the page will not be put into the history list so a user can never get back to it.

There's really no way to do this. Even if there's a way, you should not do it because any users who
surf your site find that he cannot get out of your site once he is in it will never ever wish to visit
it again.



Replace Method
================
document.replace("your_page.htm");



A second method is to make Back button invisible. However, this does not solve the problem totally because
users can always use Backspace to do a back.

Hide Back Button
===================
window.open("your_page.htm","","height=300,width=500,resizable=0,scrollbars=1");




History Trick
===============
<SCRIPT LANGUAGE=javascript>
{
var Backlen=history.length;
history.go(-Backlen);
top.window.location.href ="YourPage.asp";
}
</SCRIPT>

or this:

<body OnLoad="window.history.forward();">

Though there's no way to disable the back button, there's some tricks as described by me above.

Open a new window

<a href="mypage.htm" onClick="window.open(this.href);return false;">

Perfect. I should have thought of that! But I guess that's why I asked.
