Default Bindings <bindings>


The <bindings> element configures the default binding information for all IIS 7 Web sites.

This element can contain a collection of <binding> elements. Each element in the collection defines a separate set of binding information that a request can use to contact the Web site. For example, if your site requires users to contact it using both the HTTP protocol and the HTTPS protocol, you must define a binding for each protocol.

You can also use a <clear /> element in the <bindings> element of a <site> element to override the binding defaults inherited from the server level <siteDefaults> element.


Version Notes
IIS 7.5 The <bindings> element was not modified in IIS 7.5.
IIS 7.0 The <bindings> element was introduced in IIS 7.0.
IIS 6.0 The <bindings> collection replaces sections of the ServerBindings property on the IIS 6.0 IIsWebServer metabase object.


The <bindings> element is included in the default installation of IIS 7.

How To

How to configure the site defaults for a server

  1. Open Internet Information Services (IIS) Manager:
    • If you are using Windows Server 2008 or Windows Server 2008 R2:
      • On the taskbar, click Start, point to Administrative Tools, and then click Internet Information Services (IIS) Manager.
    • If you are using Windows Vista or Windows 7:
      • On the taskbar, click Start, and then click Control Panel.
      • Double-click Administrative Tools, and then double-click Internet Information Services (IIS) Manager.
  2. In the Connections pane, expand the server name, then click the Sites node.
  3. In the server's Sites pane, click Set Web Site Defaults... in the Actions pane.
  4. In the Web Site Defaults dialog box, specify your default options for all Web sites, and then click OK.


You can add a <bindings> element for a server, which can contain a colleciton of individual <binding> elements that define the default protocol bindings for the server. You can also use a <clear /> element in the <bindings> element of a <site> element to override the binding defaults inherited from the server level <siteDefaults> element.

Configuration Sample

The following configuration sample specifies the default bindings options for IIS 7.

            <binding protocol="http" bindingInformation="" />

Sample Code

The following code samples configure the default bindings options for IIS 7.


appcmd.exe set config -section:system.applicationHost/sites /siteDefaults.bindings.[protocol='http',bindingInformation='*'].bindingInformation:"" /commit:apphost

Note: You must be sure to set the commit parameter to apphost when you use AppCmd.exe to configure these settings. This commits the configuration settings to the appropriate location section in the ApplicationHost.config file.
