I'm trying to use my own thank you page, with an iframe that contains the download link to my e-book. I want the link to the e-book to expire, but NOT the link to get to the thank you page. I want users to be able to access that page, because I've got other content there for them in addition to the book download (like videos, GIMP brushes etc). It would even be OK if the link to the thank you page expired after, say, a year. But I do not want it to expire after a certain number of attempts.
Is this possible? I've seen someone else who uses E-Junkie with a system as I've described but I can't figure out how they did it.
Thanks in advance!
