Post values to a URL using Flash

Question

I'm dipping my toes into Flash development and wondered how to post some variables to a URL. Let's say the user has played a Flash game, packaged as an EXE or SWF embedded in HTML stored on the user's computer, not from some webpage, and would like to register the score by completing a simple form with just an e-mail address and pressing a button.

Would it be possible to do it even thought the Flash application is not on an active webpage?
