You can configure a streaming endpoint to accept traffic directed to a custom host name. Microsoft Azure must verify that you are authorized to modify DNS records for the domain. To verify authorization create a CNAME resource record with your DNS provider that points from __''{0}''.yourdomain.com__ or from __''{0}''.subdomain.yourdomain.com__ to __{1}__.
