I am doing web development. I have a page to do with credit card, which when user click "refresh" or "Back", the transaction will be performed one more time, which is unwanted. This include Browser top left "Back" & "Refresh" button, "right click->Refresh/Back", press "F5" key. This is to be done on certain cgi page only, not all of them. Can this be done using Javascript? Or any other method?
Thanks, sytee
