Parameters

 

Parameter Required Type Description

Identity

Required

Microsoft.SharePoint.PowerShell.SPWebApplicationPipeBind

Specifies the Web application to extend.

Name

Required

System.String

Specifies the name of the new IIS Web site in the Web application.

Zone

Required

System.String

Specifies one of the five zones with which the internal URL of this new extension is to be associated. This zone cannot already be in use..

The type must be any one of the following values: Default, Intranet, Internet, Extranet, or Custom

AdditionalClaimProvider

Optional

Microsoft.SharePoint.PowerShell.SPClaimProviderPipeBind[]

Adds a specific claim provider to the defined Web application.

AllowAnonymousAccess

Optional

System.Management.Automation.SwitchParameter

Allows anonymous access to the Web application zone.

AssignmentCollection

Optional

Microsoft.SharePoint.PowerShell.SPAssignmentCollection

Manages objects for the purpose of proper disposal. Use of objects, such as SPWeb or SPSite, can use large amounts of memory and use of these objects in Windows PowerShell scripts requires proper memory management. Using the SPAssignment object, you can assign objects to a variable and dispose of the objects after they are needed to free up memory. When SPWeb, SPSite, or SPSiteAdministration objects are used, the objects are automatically disposed of if an assignment collection or the Global parameter is not used.

note Note:

When the Global parameter is used, all objects are contained in the global store. If objects are not immediately used, or disposed of by using the Stop-SPAssignment command, an out-of-memory scenario can occur.

AuthenticationMethod

Optional

String

Uses Kerberos or NTLM to specify the authentication method.

AuthenticationProvider

Optional

Microsoft.SharePoint.PowerShell.SPAuthenticationProviderPipeBind[]

Specifies the authentication provider(s) that applies to a Web apllication.

Optional

System.String

Specifies a valid URL assigned to the Web application by that must correlate to the alternate access mapping configuration, in the form http://server_name.

When the HostHeader parameter is present, the value of this field is the internal URL for the Web application. The Url parameter is used to specify the public URL.

SecureSocketsLayer

Optional

System.Management.Automation.SwitchParameter

Enables Secure Sockets Layer (SSL) encryption for this Web application. If you use SSL, you must add the certificate on each server by using the IIS administration tools.  Until this is done, the Web application is inaccessible from this IIS Web site.
