I have some content on my site, say a PDF, which I want to allow visitors to download but only if they give me their name and email address (a common approach to online lead generation).
I have the form and email validation in place but I need to restrict access to the PDF until the information has been provided.
The problem I see is that once this visitor gets the URL to the PDF, I don't want them to be able to share this with someone unless their also validated.
Does anyone have any suggestions on how to go about this? I imagine it may be something along the lines of the way pages are served on member site...
Thanks in advance,
