Example configuration
Simple proxy
This example will receive HTTP requests headed towards HOSTNAME.darkmine.org, and will proxy them to the web server residing on 10.1.1.96 (port 3000). If URLs in the response have that internal IP (10.1.1.96:3000), they will be transformed to the "hostname.darkmine.org" version.
