I have some content (a certain webpage) that I wish to give to my users only after they have filled in a form (account not required), and I would like some suggestions regarding any appropriate methods to do this.

Upon submission of the form I could automatically email the user a link to the content.
or I could forward the user straight to the page.....
or I could???

Ideally I would want a page that is as difficult to get to as possible for those users who have not filled in the form. I would probably exclude a password approach.
