I'm trying to use the PRG pattern to prevent form resubmmision with Authorize.Net DPM method. My check out form post s the necesary data to authorize.net with the relay URL posts to my first ASP page on our site, then from that page I have it redirect to a second ASP page. However, when I refresh the second page, which has the URL displayed on the browser as https://secure.authorize.net/gateway/transact.dll with the content of my second ASP page, it prompt me if I want to resubmit the form, if I click on continue then the original checkout form get resubmitted to authorize.net. How do I prevent form resubmission with DPM.
I have no problem with PayPal in applying this PRG pattern in this situation because I think PayPal redirects to my relay response page while Authorize.Net posts to my relay response page.
