@hongminhee@hollo.social you can use HTTP 3xx redirects but that's not strictly necessary because you can use DNS A/AAAA/CNAME as well (and have the HTTP server respond to those names in conjunction with TLS SNI) the idea is that multiple server names can be responded to by the same Fedify software instance. in nginx it's doable with the http.server.server_name directive. https://nginx.org/en/docs/http/server_names.html SNI: https://datatracker.ietf.org/doc/html/rfc6066#section-3 does fedify expect to run behind a reverse proxy? if so, it can route requests.
