Specify the IIS application name.

An IIS application is any file that is executed within a defined set of directories in your Web site. When you create an application, you use the IIS snap-in to designate the application's starting-point directory (also called an application root) in your Web site. Every file and directory under the starting-point directory in your Web site is considered part of the application until another starting-point directory is found. Directory boundaries define the scope of an application.
