When migrating (via backup) a Discourse from one hostname to another, an admin might want to keep the old hostname but have the web server rewrite requests to use the new canonical name, e.g.: https://old.example.org/t/my-great-topic/12345 :arrow_heading_down: https://new.example.org/t/my-great-to…

This is a perfect application for a Cloudflare rule - zero server configuration. Just throw the same URL parameters at the new domain. The orange cloud will need to be enabled for the old domain name.

[image] Stephen: This is a perfect application for a Cloudflare rule - zero server configuration. Just throw the same URL parameters at the new domain. Yeah, a reverse proxy situation like Cloudflare (or I suppose your own reverse proxy of choice in front of your Discourse site) could workaro…
