You can do that with most PDF writers too, like PrimoPDF. No need then to reprocess it every time.

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.

Your plan is good. But people can still email around the PDF, making the tracking of it difficult.

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!
