IIS Enable the HTTP Keep-Alive in Powershell

The page http://technet.microsoft.com/en-us/library/cc772183(v=ws.10).aspx explains how to Enable the HTTP Keep-Alive Response Header (IIS 7)

I want to do this in Powershell by WMI

It says:

Use the following WMI classes, methods, or properties to perform this procedure: HTTPProtocolSection.AllowKeepAlive property

I've tried:

PS > Get-WmiObject -Class HTTPProtocolSection
Get-WmiObject : Invalid class
At line:1 char:14
+ Get-WmiObject <<<<  -Class HTTPProtocolSection
    + CategoryInfo          : InvalidOperation: (:) [Get-WmiObject], ManagementException
    + FullyQualifiedErrorId : GetWMIManagementException,Microsoft.PowerShell.Commands.GetWmiObjectCommand

What's the right way of using this HTTPProtocolSection class and enabling AllowKeepAlive property?

You can also set it with the Set-WebConfiguration cmdlet:

Set-WebConfiguration -Filter system.webServer/httpProtocol -PSPath MACHINE/WEBROOT/APPHOST -Value @{allowKeepAlive=$true}

To discover class in a particular namespace try this

PS c:\>Get-WmiObject -List * "root\webadministration"

and to find a match do this 

PS c:\>Get-WmiObject -List * "root\webadministration" | Where-Object {$_.name -match "Http"}


PS C:\>Get-WmiObject -Namespace "root\webadministration" -class HttpProtocolSection | Get-Member

TypeName: System.Management.ManagementObject#root\webadministration\HttpProtocolSection

__CLASS             Property      string __CLASS {get;set;}
__DERIVATION        Property      string[] __DERIVATION {get;set;}
__DYNASTY           Property      string __DYNASTY {get;set;}
__GENUS             Property      int __GENUS {get;set;}
__NAMESPACE         Property      string __NAMESPACE {get;set;}
__PATH              Property      string __PATH {get;set;}
__PROPERTY_COUNT    Property      int __PROPERTY_COUNT {get;set;}
__RELPATH           Property      string __RELPATH {get;set;}
__SERVER            Property      string __SERVER {get;set;}
__SUPERCLASS        Property      string __SUPERCLASS {get;set;}
ConvertFromDateTime ScriptMethod  System.Object ConvertFromDateTime();
ConvertToDateTime   ScriptMethod  System.Object ConvertToDateTime();

You can then do something like this to get the value of AllowKeepAlive

PS C:\> (get-wmiobject -namespace "root\webadministration" -class HttpProtocolSection).AllowKeepAlive 
True

PS C:\>$a = Get-WmiObject -Namespace "root\webadministration" -class HttpProtocolSection
PS C:\>$a.AllowKeepAlive = $false
PS C:\>$a.Put()
