title: Azure App Service accept all domain names
body: <p>Is it possible to have an App Service respond to all domain names that it receives? I would really like to be able to deploy to an App Service plan, rather than a VM. <strong>Note</strong> I am not trying to do wildcard subdomains - these require adding them through the Azure console. I am trying to accept any domain name that the app service receives. Adding and verifying each domain is not practical. </p>
  
  <p>I have a multitenant app, so this is really important to me so that customers can use their own domain names.</p>
  
  <p>I've tried adding the domain * and <em>.</em>, but it fails validation.</p>
