Restrict access to a download page until submitted email?

Hi,

I have an audio file (MP3) that I’d like people to be able to download after submitting their email address.

My current thought is to send them to a Mysite.com/download.html page and allow them to download from there. But is there a way to restrict visits to that download page only to users who have entered their email address?

Or, is there a way that I can trigger the MP3 download on successful submission of the form, without using the redirect?

Thanks for any ideas!
Doug

Have you tried direct link to your mp3 file in “RedirectURL” section? I’m not 100% sure if that works.
