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…

Update: Successfully configured the secondary domain name on the standalone installation, and issued a Let’s Encrypt certificate to handle both old and new names. Precondition: I did not yet change DNS to point folks over to the new site; I wanted things to be sure to work ahead of time. So I was u…

Not Discourse-specific, but when I need to redirect over HTTPS I just redirect everything. Meaning having a server doing the redirect from the old address to the new. Some hosting options take care of this in the background, sometimes called a “domain redirect” or “forwarding” service. I don’t even…

[图片] downey: I would rather not have to maintain a separate web server just to do a rewrite rule, if possible You don’t need to, you just need an extra server section in your config.

Maybe have a look at Setting up Let’s Encrypt with Multiple Domains

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.
