Application gateway updating multi path backend settings

Question

I want to update the backend settings for a multi path application gateway.

The initial setup is:

Path	Target Name	Backend Setting Name	Backend Pool
/foo	target	settings	pool
/bar	target2	settings	pool

The target is:

Path	Target Name	Backend Setting Name	Backend Pool
/foo	target	settings	pool
/bar	target2	NEWSETTINGS	pool

Hello @Stan Frambach ,

Welcome to Microsoft Q&A Platform. Thank you for reaching out & hope you are doing well.

I understand that you would like to update the backend settings for a multi path application gateway using Azure CLI or PowerShell.

You can use the az network application-gateway url-path-map rule command to manage the rules of a URL path map in Azure Application gateway.

To achieve your requirement, run the below Azure CLI command:

az network application-gateway url-path-map rule create -g resourcegroupname --gateway-name appgatewayname -n target2 --path-map-name rulename --paths /bar --address-pool pool --http-settings NEWSETTINGS

Just replace the resource group name, application gateway name and the application gateway rule name where this path-based rules are added in the above command and run it. It will update your target2 path to use the NEWSETTINGS.

Refer: https://learn.microsoft.com/en-us/cli/azure/network/application-gateway/url-path-map/rule?view=azure-cli-latest#az-network-application-gateway-url-path-map-rule-create

NOTE: Even though it is a create rule command, when used with the same path and target name on the application gateway, it will update the existing path target settings.

I tried this in my lab, and it works. You can see the screenshots below for reference:

After the command completed successfully, the httpsettings for the targetname "target2" was updated as below:
