SPIisSettings class

Represents the Internet Information Services (IIS) authentication settings that are shared across all of the web servers for a specific URL zone, which can be modified and propagated by re-provisioning the web application.

Namespace:  Microsoft.SharePoint.Administration
Assembly:  Microsoft.SharePoint (in Microsoft.SharePoint.dll)


<SharePointPermissionAttribute(SecurityAction.LinkDemand, ObjectModel := True)> _

Public NotInheritable Class SPIisSettings _
    Inherits SPAutoSerializingObject
Dim instance As SPIisSettings
[SharePointPermissionAttribute(SecurityAction.LinkDemand, ObjectModel = true)]
[SharePointPermissionAttribute(SecurityAction.InheritanceDemand, ObjectModel = true)]
public sealed class SPIisSettings : SPAutoSerializingObject


Use the CreateFromExistingWebSite method to create an SPIisSettings object for a specified IIS website, or use the IisSettings property of the SPWebApplication class to return the IIS settings for a particular URL zone. To return the settings for a specific zone, you can specify an SPUrlZone value as an indexer on the IisSettings property.

Setting a property value of the SPIisSettings class, such as AllowAnonymous, does not automatically propagate the new value to all IIS websites across all front-end Web servers. The properties are applied to IIS websites only after the web application is re-provisioned.


The following example displays, in a console application, the virtual directory path for the Default URL zone of a specified web application.

Dim uri = New Uri("http://MyServer")
Dim webApplication As SPWebApplication = SPWebApplication.Lookup(uri)
Dim iis As SPIisSettings = webApplication.IisSettings(SPUrlZone.Default)
Console.Write(iis.Path + " == " + iis.PreferredInstanceId.ToString())
System.Uri uri = new Uri("http://MyServer");
SPWebApplication webApplication = SPWebApplication.Lookup(uri);
SPIisSettings iis = webApplication.IisSettings[SPUrlZone.Default];
Console.Write(iis.Path + " == " + iis.PreferredInstanceId.ToString());
