[tech] reverse proxy gemini

[Hugo Wetterberg]

I had almost the same use-case for my small gemini server and wrote a
proxy that only does vhost routing:

gemini://repos.wetterberg.nu/~hugo_wetterberg/gemini-proxy

But if you're serving static files/some CGI you're probably better off
following mieums advice and use a server that uses different docroots
for different hostnames. Then you don't have to layer different proxies
and servers, and it's easy to combine that workflow with git post-
recieve hooks that generates the static files.
