Managing Applications in IIS 7
Applies To: Windows 7, Windows Server 2008, Windows Server 2008 R2, Windows Vista
An application is a grouping of files that delivers content or provides services over protocols, such as HTTP. When you create an application in IIS, the application's path becomes part of the site's URL.
In IIS 7, each site must have an application which is named the root application, or default application. However, a site can have more than one application. For example, you might have an online commerce Web site that has several applications, such as a shopping cart application that lets users gather items during shopping and a logon application that enables users to recall saved payment information when they make a purchase.
In addition to belonging to a site, an application belongs to an application pool, which isolates the application from applications in other application pools on the server. In the case of managed code applications, make sure to associate your application together with an application pool that is running the .NET Framework version that your application requires.
For information about the levels at which you can perform these procedures, and the modules, handlers, and permissions that are required for these procedures, see Applications Feature Requirements (IIS 7).
