I'm selling this ebook but the problem is, the way its set up the buyer can just look at the source code and find the place to download it. I want to set up a more secure way to do this. I was told Paypal IPN would solve this. I could set it up so after the purchase was made I could email them the file or give them some info or something. I looked into it but I am completely lost. There seems to be many different ways to set it up. Using Java, PHP, Perl ect.. I really dont know which one to do or how to do it. Any help? Thanks.
I haven't tried it but I would rather not have to install Joomla. But if I can't find anything else I could try it.
