+Configuring Caddy as a reverse proxy to HTTP golang servers on port 8080 with automatic TLS and health checks can look like this:
+```
+yourdomain.com, www.yourdomain.com
+
+reverse_proxy / {
+	to 192.101.153.159:8080 192.118.109.166:8080
+	health_path /health
+	health_status 200
+	transport http {
+		read_buffer 4096

+**Note:** do not forget to set up health handlers for the golang webservers returning an HTTP 200 response or Caddy 2 will fail the health check and deem the node unreachable.
