+Multi-domain operation means that a Contao installation can be accessed via more than one domain whereas each of them produces a different output. The latter is a very important detail because you can theoretically make the same website available via different domains. This, however, is not a good idea in terms of search engine optimization (think about "duplicate content") nor does it have anything to do with the multi-domain operation of Contao.

-For a real multi-domain operation, you need several starting points in yourContao site structure in addition to several domains. If you only have one starting point, your installation is only accessible under several domains. In this case, it is best to choose a main domain and redirect the other domains to it. This redirection can usually be set up in the control panel of your server or in a file`.htaccess`.

 Let's assume that an agency is looking after a company with several websites and wants to manage them with a central Contao installation. For this purpose, the following domains were registered:
 
-- `firma.at`
-- `firma.ch`
-- `firma.de`
+- `company.org`
+- `company.com`
+- `company.us`
 
-All domains are routed to the central installation, which means that Contao can be reached under all three domains. To ensure that the frontend loads the appropriate website for the domain, three start points of a website must be created in the site structure and the domain must be`Domainname` entered in the **"DNS settings"** section.
