  order-step4.php:
  credit card informationg get passed to this page, and it contacts credit card place to authenticate.... if sucess forward to thankyou.php

  thankyou.php
  if a user hits back, it hits back arrorow(to order-step4.php) it charges card again

  i tried putting a database call at the top of order-step4 to check order status or current order and to not charge again, but its not loading that, i am guessing cause its cached.

  also tried doing a pragma no-cache.
