I want to be able to let my users pay for a program and then download and install it. I'm using Verisign's payflow link. My site is built using asp.net.
A few questions:
- How can I make it so users can only download the .exe file once they have paid?
- How can I hide the url of the download from the user so they don't download it again and again?
-Anything else I should keep in mind as I do this?
Thanks for any help you can offer...

they decided to do it this way because the particular
tool that they chose has expiring cryptographic keys
in the urls.
i think the way it is going to happen is that the
return page from the processor is going to feature
the download url in it. since the key will expire, any
bookmarking is futile.
mind you, should the software itself not be protected
by registration keys? what happens if one copy
gets paid for and posted on the net?
anyways, if you want to find the isapi filter, search on
"iis hotlink" and look on the first page of
results. another query that will work is
"anti-hotlinking test tool"
