You could expire the page or use a workaround like overwrite the last 
history-entry(using location.replace()) , but that?s not entirely safe 
(you can still type in the url).

Disabling the back-button or other crappy solutions aren?t normally 
appreciated by the user ;-)

I want to prevent the user from going back to the previous page after
clicking
the [Submit Payment] button and advancing.
 
Thanks
