How to add a second domain name?

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.


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

We can take this on as a project if you’re interested.

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


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