The credit card info is still present when a user clicks the back button. This is a potential security issue for the setting in which we will be accepting form registrations/payment (public kiosk). Is there a way to make sure the CC field contents are cleared from the back-forward cache?
Even outside of the kiosk environment this is generally considered best practice for accepting CC info.
You could have some JavaScript written that clears all form fields on page load, that might help the issue. Beyond that, we can't control browser behavior. Clicking back wouldn't necessarily mean that any of our hooks would run, thus allowing Gravity Forms to control those fields, so there is little we can do to help the issue. This is a very common issue out in the world for all sorts of situations, but beyond the potential JavaScript option, I don't know of a working, trusted solution.
