Greetings, I am wondering how to keep a second domain pointing to the same instance? I have set up a discourse instance with domain name https://firstdomain, for some reason, I have to set up a second domain https://seconddomain pointing to the same instance and keep it in the address bar when people visit it. I tried all I can but everytime visiting the seconddomain, it will be redirected to firstdomain in the address bar. Any help would be greatly appreciated. Thanks.

That’s on purpose. https://github.com/discourse/discourse/commit/e7001f879a2cd87cba8dbfc5bb4e0f4f9023471c

Thank you for your reply. so is there any other way to achieve the same goal? Like ngnix reverse proxy?

A reverse proxy would require nasty voodoo content rewriting. I think the only sane way is a plugin: Forcing hostname has broken support for Onion Services - #4 by sam We can take this on as a project if you’re interested.

Discourse inserts link rel=“canonical” tags to the primary hostname so that already has been mitigated.

There are also SEO reasons not to have two domains serve the same content.
