Is there a way to add a virtual directory to Visual Studio Development Server?

Question

I\'m using the Visual Studio Development Server, with a specific port. Is there a way to add a virtual directory to it?

EDIT:

Sorry, I wasn\'t very clear.

Answer 1

The Visual Studio Development Server is codenamed Cassini.

From ASP.NET 2.0: A Getting Started Guide

Cassini doesn't support virtual directories, security settings, 
or any of IIS's other fancy features; it's just a very simple web server 
that gives you the basics you need to get up and running.

I am using the IIS which is included with Windows XP Pro. It only allows one website without tweaking but does have virtual directories. If you are on Vista, you can setup multiple sites in IIS from what I have heard.
