Hi I am sorry if this question has been asked before but I am looking for some sort of download authentication. In other words if I am going to give the user a link to a file, I want to make sure only that person will get it, and get it only once! Is there a simple solution without setting up the whole database. Even better if it's possible to have an ecrypted web link that will let you download a file from my FTP server just once, after that the link becomes invalid.

Thanks.
