I am implementing credit card processing on my site and I am using a HTML form and processing the cards. I have only tested this for now. if some one view the source they can view the action page.
is there a way i can avoid this. is there a way to expire the page when user clicks the browser back button, so that he has to reload the page if he wants the view the previous page.
please explain the best practice. I am using coldfusion to make this form.
