the very accessible thank you download pg

[webgal]

I have signed up with an affiliate. Then I noticed that after the sale, it redirects the buyer to the download page. I guess I had expected something like my cube cart delivers, which is a download link via php so they can't tell where it's downloaded from. Not easily anyway.

So my dilemma is how to create something that downloads but doesn't lead them to a page they can bookmark and send to all their friends on the planet. Honestly, you'd think that some of these affiliates would have resolved that one.

My Question: Is there a way to offer up a particular type of page that would encrypt the download? Or is this a huge undertaking that a non-php pro should never undertake.

I thought of having a download page and you'd have to plug in an e-mail to get the download and deliver it that way but the back end part of the php to make it happen is out of my tech league.

Any suggestions?
