If you are reading this page, it is because you have received an order which tripped a warning message similar to the following: Warning! A page was submitted from an unfamiliar URL: http://www.yoursite.com/yourproduct.html Or, it may look like this: Warning! A page was submitted from an unfamiliar URL: Probable local file submit or browser location bar manipulation. You are probably seeing this early in your site development, since adding product to the shopping cart from a page on your local disk drive will trigger the warning. The warning is also triggered by someone ordering from a page under a domain name you don't have listed in the cart configuration form as one you control. There is also one version of Norton Firewall for Windows that BLOCKS the referral document from being sent, so a minor % of your orders will show: Probable local file submit or browser location bar manipulation. Don't be unduly alarmed when you see that. Just look a little closer at the order, and if it seems ok, don't worry about the message. Why do we insert warnings? Here's the explanation: We decided that it might be prudent to make sure that someone didn't save one of your product pages to disk, change a price, and add a "newly reduced price" item to their shopping cart. They might then place an order, and if you didn't notice, you might get burned. It's never happened to our knowledge, but it is possible to do, so we decided to put in a warning message if an item was added to a cart from somewhere other than your site. What HAS happened in the past is that some prankster will figure out that they can save a page and change a price, and then they proceed to place an obviously bogus order with a fake name, etc. They never place real orders, or you'd know who they are, and they'd be guilty of fraud as well. We've had one reported case like this. It's nothing to worry about if it happens. Just delete the order. Any such case will have the "Probable Local File submit" warning in the order. The feature works well, but we had to implement a section in the cart configuration form for it. In it, you list the main URLs that we should expect to see product come from. In most cases, just put in: http://www.yoursite.com http://yoursite.com Thanks!
