Hi @francislavoie, thank you for taking the time to take complex subject matter and turn it into language the average layperson, like myself, can begin to appreciate. You would be a terrific educator if you chose this line of work.
I look at my Caddyfile and realise it’s matured a lot, but it took a lot of patience from the community, especially you, to help me bring it to that point. I do also like what @Rob789 has done to encrypt comms between backend services and Caddy in his wiki article Use Caddy for local HTTPS (TLS) between front-end reverse proxy and LAN hosts. On the other hand, I love the elegance and summary perspective that the map directive brings to Caddyfile (it reminds me of the vlookup function in Excel). Where I think it’s important to encrypt backend comms, I’m going to try to find a way to skirt around the map directive to implement this.
