Hi, is it possible to set the variable 'rootpage_id' in my RealUrl configuration dynamically? I found an interesting approach: $RootPID = array( 'www . domainname . de' => '2', 'www . domainname . de' => '22', 'www . domainname . de' => '45' ); 'rootpage_id' => $RootPID[$_SERVER['HTTP_HOST']] But this is not really dynamic.
