 - `PROXY_BASIC_AUTH=user1:password1,user2:password2,user3:password3` adds basic auth feature to your configured `VIRTUAL_HOST` server root.

 ## Default Server
 When request comes for a server name that is not registered in `nginx-proxy`, It responds with 503 by default.
 If you want the requested to be passed to a container instead, when setting up the container you can add `PROXY_DEFAULT_SERVER=true` environment along with `VIRTUAL_HOST`.
