To configure a host header

You can perform this procedure by using the user interface (UI), by running Appcmd.exe commands in a command-line window, by editing configuration files directly, or by writing WMI scripts.

To use the UI

1. Open IIS Manager. For information about opening IIS Manager, see Open IIS Manager (IIS 7).
2. In the Connections pane, expand the Sites node in the tree, and then select the site for which you want to configure a host header.
3. In the Actions pane, click Bindings.
4. In the Site Bindings dialog box, select the binding for which you want to add a host header and then click Edit or click Add to add a new binding with a host header.
5. In the Host name box, type a host header for the site, such as www.securewebs.com.
