html - Stop browsers asking to resend form data on refresh

Question

I have a form submission via POST. I submit the form, and all is well, however if I try to reload the new page that the form goes to after submission, I get the "Do you want to resend data" message (Firefox). It might happen in other browsers too, but I'm not sure.

Is there a way to stop this message popping up so I can go ahead and refresh the page? It's not good for production environments - users may submit the same form twice!

You need to use the the POST-Redirect-GET pattern.

Make your form respond with a redirect to a GET request.
This way, when the user refreshes the page, it will only re-send the GET.
