Domain Park

When visiting a site from a domain name different than the $base_url set in settings.php, look for that domain in field_domain and go to the node (or, possibly, other entity) associated with that domain.

This is done as a redirect, so that if you have registered http://longmeaninglessexamplenoonewouldtype.com and it is pointed to a Drupal installation (main URL http://example.com) with Domain Redirect enabled, you will be taken to http://example.com/project-about-long-meaningless-example-no-one-would-type for example, provided that node had http://longmeaninglessexamplenoonewouldtype.com in its Domain field (which must have the machine name field_domain, and this is not presently created for you).

Domains are to be entered in this field without http://.
