Parameter Required Type Description

ApplicationPool

Required

System.String

Specifies the name of an application pool to use; for example, SharePoint – 1213. If an application pool with the name provided does not exist, the ApplicationPoolAccount parameter must be provided and a new application pool will be created. If no value is specified, the default application pool will be used.

Name

Required

System.String

Specifies the name of the new Web application.

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.

ApplicationPoolAccount

Optional

Microsoft.SharePoint.PowerShell.SPProcessAccountPipeBind

Specifies the user account that this application pool will run as. Use the Get-SPIisWebServicApplicationPool cmdlet to use a system account.

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.

NoteNote:
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

System.String

Uses Kerberos or NTLM to specify the authentication method. If no value is specified, the default NTLM is applied.

AuthenticationProvider

Optional

Microsoft.SharePoint.PowerShell.SPAuthenticationProviderPipeBind[]

Specifies the authentication provider or providers that apply to a Web application.

Confirm

Optional

System.Management.Automation.SwitchParameter

Prompts you for confirmation before executing the command. For more information, type the following command: get-help about_commonparameters

DatabaseCredentials

Optional

System.Management.Automation.PSCredential

Specifies the Windows PowerShell Credential object for the database user account.

DatabaseName

Optional

System.String

Specifies the name of the initial content database for the new Web application.

The type must be a valid database name; for example, ContentDB1. If no value is specified, a value in the format WSS_Content_<GUID> is auto-generated.

DatabaseServer

Optional

System.String

Specifies the database server name. The type must be a valid database server name, in the form SQL1; where named instances are used, the format can appear as server\server. The default SQL server instance is used if a value is not provided.

HostHeader

Optional

System.String

Specifies a valid URL assigned to the Web application that must correlate to the alternate access mapping configuration, in the form 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.If no value is specified, the value is left blank.

Path

Optional

System.String

Specifies the physical directory for the new Web application in the virtual directories folder. The type is a valid path, in the form C:\Inutepub\wwwroot\MyWebApplication. If no value is specified, the value %wwwroot%\wss\VirtualDirectories\<portnumber> is applied.

Port

Optional

System.UInt32

Specifies the port on which this Web application can be accessed. This can be any valid port number. If no port is specified, a nonconflicting port number is automatically generated.

ImportantImportant:
If you specify a port number that has already been assigned, IIS does not start the new site until you change either the port number of the new site or the port number of the old site.

SecureSocketsLayer

Optional

System.Management.Automation.SwitchParameter

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

ServiceApplicationProxyGroup

Optional

Microsoft.SharePoint.PowerShell.SPServiceApplicationProxyGroupPipeBind

Specifies a custom service application proxy group for the Web application to use. The Web application will use the proxies in this proxy group to connect to service applications. If this parameter is not specified, the default proxy group for the farm is used.

SignInRedirectProvider

Optional

Microsoft.SharePoint.PowerShell.SPTrustedIdentityTokenIssuerPipeBind

Sets the sign-in redirect URL to point to the URL that is defined in the specified authentication provider.

SignInRedirectURL

Optional

System.String

Specifies the sign-in redirect URL for the Web application.

Url

Optional

System.String

Specifies the load-balanced URL for the Web application.

UserSettingsProvider

Optional

Microsoft.SharePoint.PowerShell.SPUserSettingsProviderPipeBind

WhatIf

Optional

System.Management.Automation.SwitchParameter

Displays a message that describes the effect of the command instead of executing the command. For more information, type the following command: get-help about_commonparameters

------------------EXAMPLE-----------------------

$ap = New-SPAuthenticationProvider
New-SPWebApplication -Name "Contoso Internet Site" -Port 443 -HostHeader sharepoint.contoso.com -URL "https://www.contoso.com" -ApplicationPool "ContosoAppPool" -ApplicationPoolAccount (Get-SPManagedAccount "DOMAIN\jdoe") -AuthenticationProvider $ap -SecureSocketsLayer
