Note The FTP 7. Note To support ASP.In IIS, you can create sites, applications, and virtual directories to share information with users over the Internet, an intranet, or an extranet. Although these concepts existed in earlier versions of IIS, several changes in IIS 7 and above affect the definition and functionality of these concepts. Most importantly, sites, applications, and virtual directories now work together in a hierarchical relationship as the basic building blocks for hosting online content and providing online services.

This article provides a quick overview of applications in IIS 6. In IIS 6.

Understanding Sites, Applications, and Virtual Directories on IIS 7

Although they were discussed as separate concepts, and they were conceptually different from a functionality standpointan application was not a physically separate object from a virtual directory. The site root is an exception, as it was implicitly treated as an application even if those properties were not set.

These technologies provided additional features and processing for applications hosted in IIS 6. The important question for IIS 6. IIS 7 and above formalizes the concepts of sites, applications, and virtual directories. Virtual directories and applications are now separate objects, and they exist in a hierarchical relationship in the IIS configuration schema. Briefly, a site contains one or more applications, an application contains one or more virtual directories, and a virtual directory maps to a physical directory on a computer.

As in IIS 6. However, each site must contain at least one application, which is named the root application.

And each application including the root application must contain at least one virtual directory, which is named the root virtual directory. These objects work together to form the site. An application is an object important to the server at runtime. NET request-processing pipelines have merged in IIS 7 and above so that content can take advantage of functionality previously provided for only managed code applications. For example, each managed code application runs in an Application Domain AppDomain.

An application can have several virtual directories, and each one will be served by the same AppDomain as the application to which they belong. The following sections explain sites, applications, virtual directories, and their related configurations in more detail.

A site is a container for applications and virtual directories, and you can access it through one or more unique bindings. The binding includes two attributes important for communication: the binding protocol and the binding information.

The binding protocol defines the protocol over which communication between the server and client occurs. The binding information defines the information that is used to access the site.

It takes the logs to your storage location and interprets the data by displaying it in dashboards with full, customizable graphics that provide a quick understanding of the saved results.
