There are so many options and parts of this thing that I'm all confused. Again.

I have a need for a user to click a link that downloads a file. My registration Wizard generates a url holding an encrypted key, and I have a function that can convert that encrypted key into a registration.ini file.

What does the code look like on the server that processes that request, and what kind of object is it in?

This is not in an Existing Web app, it's a new "clean page" project. What do?

I don't see anything similar in the examples to guide me.
