   case 'www.1.eu':
      // if the http_host is modx-templates.com, switch the context to web
      $modx->initialize('web');
      break;
   case 'www.2.eu':
      // if the http_host is modx-templates.com, switch the context to web
      $modx->initialize('2-de');
      break;
  default:
      // by default / if no other rule can be applied, load 'web' context
      $modx->initialize('web');
