Drop-down boxes downloadable?

[RedFox]

It's one thing i've never been able to find out.
See: http://www.sydneydancecompany.com/feed.shtml

Notice how you can select different applications, click download and it'll work? I'm assuming it's using a get function but i can't find anything else on it.

he uses javascript to set the URL value depending on which option in the select has been chosen. submit then submits to a page which recieves the value of the URL box and downloads the file. easy
