Don't give anyone a direct link to the secured content but instead generate a unique serial number and give them a link to a handler with the serial number.
getContent.cfm?serial=91080981 And then let people download with each serial number only once. If they go to the url a second time, display a message saying the file has already been downloaded. Of course you'll have to deal with issues where a customer needs to download it a second time legitimately, such as an error during the initial download. But this will get you started.
