I have a form with multiple submit buttons. On click, each button sets a cookie to a different value, which changes what the invoked PHP will show. When in the next screen, when I press F5 (or refresh icon) it looks like Firefox is going back to the prior screen and acting like the first button was pressed (changing the cookie value). I tried this on other browsers and all have the same error. Does not make sense to me, I may try a few workarounds.
