Adding a notification alert whenever a custom domain is mapped to an App Service.
We have a requirement of configuring all the public facing websites behind Web Application Firewall. The current setting only enables us to manually look up the domains mapped to each App Service and then configure them behind WAF. This way, there is a chance of missing out on a few newly added domains if they are not checked manually. So, if we were able to receive a notification alert each time a new custom domain is mapped to any App Service, we would then immediately configure it behind WAF.
