Add proxy element to applicationHost.config in system.webServer section via Powershell

Question

I am trying to add <proxy enabled="true" /> element under system.webServer section.

Add-WebConfigurationProperty -Filter '/system.webServer/proxy' -Name . -Value @{ enabled="true" }

Above command does nothing.

Add-WebConfigurationProperty -Filter '/system.webServer' -Name 'proxy' -Value @{ enabled="true" }

Above command throws error: Property proxy is not found on system.webServer

Add-WebConfiguration -Filter '/system.webServer/proxy' -Value @{ enabled="true" }

Also does nothing.

Set-WebConfigurationProperty -Filter '/system.webServer/proxy' -Name 'enabled' -Value 'true'

Shows warning: Target configuration object '/system.webServer/proxy is not found at path 'MACHINE/WEBROOT/APPHOST'.

I find these commands very counterintuitive. What is the right way to add new element?

EDIT:

I was testing these commands on Windows 2019 Core with default IIS 10.0

I have Windows Server 2012 R2 with IIS 8.5

I can setup proxy on Win2012 with command appcmd set config -section:system.webServer/proxy /enabled:"true" /commit:apphost, but the same command doesn't work on Win2019. It shows error Unknown config section "system.webServer/proxy". So, this setting may be not valid for IIS 10.0

First you need to make sure ARR has install like Lex Li said.

Then try this powershell command, it can work well in my server 2019.

Set-WebConfigurationProperty -pspath 'MACHINE/WEBROOT/APPHOST'  -filter "system.webServer/proxy" -name "enabled" -value "True"
