Redirect Multiple Site Addresses/Labels (Including IP) to a Specific Site/Label in Caddyfile

Question

I have a server running Caddy that can be reached under the domain rv2680.1blu.de and marleneschulz.info. Both DNS A records point to the IP address 178.254.7.175. I want to make sure Caddy always redirects the user to https://marleneschulz.info.

Here is my working Caddyfile :

www.marleneschulz.info {
    redir https://marleneschulz.info
}

https://marleneschulz.info {
    root /app/marlene/shared

    proxy / django_prod:5000 {
        header_upstream Host {host}
        header_upstream X-Real-IP {remote}
        header_upstream X-Forwarded-Proto {scheme}

        except /static
    }

    log stdout
    errors stdout
    gzip
}

How can I prevent Caddy responding with e.g. 404 Site rv2680.1blu.de is not served on this interface by explicitly defining to redirect every request from rv2680.1blu.de:80, rv2680.1blu.de:443, 178.254.7.175:80, 178.254.7.175:443 and marleneschulz.info to https://marleneschulz.info?

I am also a bit confused since the docs state nothing about the www. prefix. I want to be as explicit as possible.

You can define a couple catch-all sites and redirect them:

http://, https:// {
    redir https://marleneschulz.info{uri}
}

(I added {uri} because I assume you want to preserve the URI in the redirect.)

Using http://, https:// as site addresses is the same as using :80, :443.

There's nothing special about the www prefix, either. If you wanted to enumerate all the sites you want to redirect, you would specify www.marleneschulz.info as one of them, just as with any other sites.
