annoyingly, HAProxy doesn't like mixing TLS termination vs passthrough, and i haven't figured out how to get the gateway's own web UIs (yes, plural, it's dumb) to discover my TLS certs so that they can do their own termination and have haproxy _only_ do SNI-based routing

@techaro.lol just wanted to say I've implemented your Advanced HAProxy approach for Anubis and it feels a lot better (just like how iocaine feels better as an SPOA engine)
