For example, this results in two items added to the cart. This error >appears to occur every second time if you go back and resubmit.This is not an error. In fact, it is an error *not* to allow the second submission. There are plenty of sites that want to add the same product to the cart on 2 different occasions (1 pair of red tennis shoes, and a second pair of green) as 2 different lineitems. The browsers that do so much caching that they don't actually send the second request are in error. When you are dealing with dynamic pages, as WebCatalog does, you must let WebCatalog see all of the form postings so *it* can decide if there's an error or not.To solve your situation, where you don't want a second item added to the cart, you can put WebDNA into the cart page that examines contents of the cart and disallows the second $Add of an identical product. The choice should be up to you, the WebMaster, and not the browser.Grant Hulbert, V.P.
