Extending a Web Application in SharePoint 2010

The steps to extend a Web application using Windows-classic authentication in Windows PowerShell is as follows:

·         On the Start menu, click All Programs.

·         Click Microsoft SharePoint 2010 Products.

·         Click SharePoint 2010 Management Shell.

·         To extend a Web application to the same port, but with a different host header, at the Windows PowerShell command prompt, type the following command:

Get-SPWebApplication –Identity <Identity> | New-SPWebApplicationExtension -Name

<Name> -HostHeader <HostHeader> -Port <Port> -Zone <Zone> -URL <URL>

Where:

·         <Identity> is the Web application that you want to extend.

·         <Name> is the name of the new IIS Web site in the Web application.

·         <HostHeader> is the host name assigned to this zone of the Web application.

·         <Port> is the port on which this zone of the Web application can be accessed.

·         <Zone> is the zone with which this new extension is to be associated.

·         <URL> is the public URL for this Web application zone.
