When Caddy was first released I tried, and failed, to get Caddy to serve an https site locally. Is that possible now? The docs[1] hint that it could be if I add an entry to my hosts file pointing an IP address of, say, a Docker container, as that wouldn't technically be localhost or an IP address. It doesn't explicitly say it's possible though. Adding something to the tutorials would be immensely helpful if it does work.
