Prevent Brower From Going Back To Credit Card Page

["Joe Giusto II" <midrange@xxxxxxxxxxxx>]

I am trying to prevent users from using the Back button in the web browser
to get back to the page where the credit card number was entered.  Or
alternatively, be able to erase that page from the history log or back
button log.

The closest I have come is with this JavaScript, which will throw the page
forward again when the user hits the back button.

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

But does not prevent them from using the drop down arrow on the back button
to go back several pages to get to it.

I realize the script will work if I put it on each page, but I need to allow
them to go back and make changes until the final order page is accepted or
rejected.  That is when I write out a confirmation page with the script in
it.
