.. but surely even if he uses this one-time method then the person who clicks the link for the mp3 file will still get the file? albeit with added server load as it is copied first then deleted - not to mention the additional script work that would be needed?
Ultimately, there is no way to protect the content if it is web-facing, the web is a public resource and anything put on there can be grabbed by anyone. If he really wants to protect the files then he would need to encrypt the files at source so when someone who is not authorised gets it, they can't do anything with it as they don't have the de-cryption key. -----Original Message----- From: Jonathan Zuckerman [mailto:j.zucker...@gmail.com] Sent: Thu 3/26/2009 18:06 To: users@httpd.apache.org Subject: Re: [us...@httpd] How to prevent a site to be grabbed ? Use a one-time pad. Every URL to an mp3 is not an actual resource, it's a link that is generated when the user indicates a desire to download the mp3, and the mp3 is then copied from a protected place to a public place. After that link is accessed one time, a script is run which outputs the mp3 as a file, then deletes the public mp3 and invalidates the link. Hashing, cryptography, this is a classic computer science problem ;) On Thu, Mar 26, 2009 at 2:38 AM, Octavian Rasnita <orasn...@gmail.com> wrote: > Password-protect it, and don't give the password to anyone. :-) > > If someone sees a page from your site, that page was already downloaded to > the visitor's computer, and a visitor can create a program that download all > the pages which he can access using a browser. > > Octavian > > ----- Original Message ----- > From: "J.
