+### Disable automatic TLS certificates and https
+
+One might want to use reverse proxy without buying a domain, and without opening

+  reverse_proxy server-blue:80
+}
+
+test.example.com:80 {
+  reverse_proxy 192.168.1.100:80
+}
+```
+
+What's also needed, is a way for your browser to be send to docker-host's
+ip address when `example.com` is entered as url.<br>
