pages and virtual folder

In my spare time I am working on a personal project for Internet Marketing.
I am temporarily hosting this project myself until it goes live.

I created a virtual directory as shown in the video.
What I want is my default.aspx in the folder where the site starts and the scripting behind it in the virtual folder.
This default page does contain some controls that need scripting, but I don't want the prg in the homepage folder.

How do I get on with that?
