Caddy

Caddy is built with xcaddy including the cache-handler plugin.

The Caddyfile is:

{
  order cache before rewrite
  cache
}

:8006 {
  cache {
    default_cache_control no-store
  }
  reverse_proxy http://127.0.0.1:8000 {
  	transport http {
  		dial_timeout 10s
  	}
  }
}

(default_cache_control is set so that Caddy doesn't cache things without Cache-Control; unfortunately, it is passed downstream)
