I think with the new CFPDF stuff that you can set the PDF to not allow saving or copying (among other things). If you did a cfcontent to the browser, rather than attaching to an email, and set it to not allow save or copy it would seem to provide a measure of protection that would thwart a casual user.

You know, register for the newsletter, and we'll send you a free white paper. I was just attaching the white paper PDF to the e-mail, but I'm concerned that is not the best practice. Spam filters might strip off the attachment. So, maybe it would be better to put a link in the e-mail that let's them download the file. But, I don't want the link passed around, so I need to make sure they can only download it one time. What's the best way to accomplish something like this? I thought about adding a URL parameter to the download link, and then keeping track to see if the file had already been downloaded. I think I should also use <cfcontent> to serve up the file, and I can then put the file in a directory that is not web accessible. Is this a good plan? Anything I am missing? Oh yea, I'm on a shared host running CF7. I'll upgrade to CF8 soon, but I need to make this work using CF7. Thanks for listening!
