[tech] Gemini reverse proxy

[panda-roux]

I am using HAProxy.  Here's my config for some inspiration: https://gist.github.com/panda-roux-dev/9142cf01ad3b29aa86120c7cd90d5b95

It was a headache to set up because I'd never used it before and 99% of the search results online are concerning its HTTP usage, but eventually figured out something that works in TCP-mode.

Note that I'm using TLS passthrough rather than having HAProxy take care of encryption.  This is in order to let each back-end server use certificates with its corresponding domain name listed in them.

Good luck.
