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.-dhs

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!
