#Redirect all requests to index.php

Redirect all requests to the index.php. Activate the .htaccess or (better) add the config to the vhost config.

RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^.*$ /index.php [L]

In the DNS point all hostnames with redirects only to this server (i.e. with a CNAME).

If you don’t have a single vhost in the webserver then additionally add the domains to “catch” as ServerAlias.
