Unless you do all of your adding to carts in a context (where you can decide whether they have already added this item), you are stuck. When a page is reloaded, the browser (as you have discovered) submits EXACTLY the same variables as previously.One thing you can do is have the target of the add be an intermediary page which contains only a redirect to the actual shopping cart page.

Here is the flow: SearchPage ---submit---> AddMePage ---redirect--->ShoppingCartNo amount of hitting refresh on the ShoppingCart page will have any effect, since the form variables will be eaten by AddMePage.If you are clever, you can even have the ShoppingCart page redirect to itself, which we do since Netscape doesn't always display the initial-- John Peacock Director of Information Research and Technology Rowman & Littlefield Publishing Group 4720 Boston Way Lanham, MD 20706 301-459-3366 x.5010 fax 301-429-5747------------------------------------------------------------- This message is sent to you because you are subscribed to the mailing list
