How to protect download page
I think a php programmer should know how to do this. I'm releasing an ebook soon, and i'm allowing people to download it, however, how can i prevent people from sending the download url page out, and is there a way i can disable an ebook after someone have it? Do anyone now a script or can make one?Thanks

Hehe, I was thinking the same thing. :p superflytrainer: I would use user authentication with image verification. This would make it so each user would have to register/login and type in the auto-generated image characters in order to download your file. You can read a decent overview here. There is no way to limit the spread of your eBook file, however. Well, at least not with PHP.

So those the image verification only limit the download to that computer? I now that it stops robots from oopening up certain accounts but wasn't sure if it can prevent people from sharing your download page.

Yeah, and what if they delete or modify the cookie? Or have cookies disabled?
 Security is not a trivial thangy. I perceive some reading is in order, prior to 'fixing' the problem.
