Managing Sites in IIS 7
Applies To: Windows 7, Windows Server 2008, Windows Server 2008 R2, Windows Vista
A Web site is a container for Web applications, and you can access it through one or more unique bindings. A Web site binding is the combination of an IP address, a port, and the optional host headers on which HTTP.sys listens for requests made to that Web site. Web site bindings use the HTTP or HTTPS protocols. You can create Web sites and share information with users on the Internet, an intranet, or an extranet.
In IIS 7, you can configure a site to use protocols other than HTTP and HTTPS and you can add multiple bindings to a site. For example, if an application in your site requires a protocol that is supported by Windows Communication Foundation (WCF), such as net.tcp or net.msmq, you can add a binding for that protocol in addition to the Web site binding that uses HTTP or HTTPS. This enables the applications in your site to use the same site configuration settings, such as the physical path of site content, regardless of the protocol or protocols that you configure in the site bindings. If you download and install the new Microsoft FTP Publishing Service for IIS 7, you can also add an FTP binding to a site to enable publishing.
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 Sites Feature Requirements (IIS 7).
