Add virtual directory as application in IIS 7
A virtual directory is a directory name alias (also referred to as path) that you specify in IIS and map to a physical directory on a local or remote server. The directory name then becomes part of the application's URL, and users can request the URL from a browser to access content in the physical directory, such as a Web page or a list of additional directories and files. If you specify a different name for the virtual directory than the physical directory, it is more difficult for users to discover the actual physical file structure on your server because the URL does not map directly to the root of the site.
Setting up a virtual directory as an application will allow you to run ASP.NET applications and also allow you to configure the virtual directory separately from the main site. Normally all settings and configuration will be inherited from the parent site or IIS server.
