I have a working Drupal 6 using a shared Drupal install on a shared Linux server. I've just installed D7. I'm not sure if sites.php is set up correctly (see below). And I can't find good information on this sites.php file to be sure I set it up correctly. This Drupal.org page describes the correct installation situation, but sadly does not mention sites.php (>_<) This Drupal forum poster has the same "Server Not Found" error, but shows completely wrong sites.php example--the set up is not clear.
Is sites.php do the same thing that a symbolic link folder did in Drupal 6. Can I ignore this file?
My sites.php file,
$sites['mondo7'] = 'mondo7.mydomain.com';
and I tried it the other way,
$sites['mondo7.mydomain.com'] = 'mondo7';
Both show up "Server Not Found".
