Hi I just installed Simple Pay Pal shopping cart on my word press website. It is a very simple and helpful tool but has a huge issue with it. When the client pays the fees and goes to the Download Page, that page has a URL which can be copied. It is not the encrypted/protected URL. Anyone can copy that URL and post it to forums and blogs and then download the ebook/digital product from that URL. Is there any way to stop it OR to develop a system in it where you can have a encrypted/protected URL. Please advice on it. Thanks
