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.
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:
