For the one-hand handful of us running #9front routers, my first real C program in many years, relay, is now up on http://shithub.us/flowerss/relay/HEAD/info.html It’s a simple hostname-based HTTP/HTTPS relay in the vein of relayd from OpenBSD or haproxy. It allows you to expose multiple backend web services through a single ip address. It even has round robin load balancing.
