Disable back button of browser using javascript

[kavita vala]

Hello all i want o disable back button using javascript when user logout.

I do it using

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

But it goes one page back. On next click on back it goes back to index page.
Than how can i totally disable back button or give any page ref. to back button.

How can i do this
