Domain Swap 404

This little module redirects 404's to another domain, keeping the structure of the url in tact. For example, if a user tries to go to http://www.foo.com/directory/subdirectory on your Drupal site, and that page doesn't exist on your Drupal site, they will be redirected to http://www.bar.com/directory/subdirectory.

You can set different redirects for different url patterns. So users going to http://www.foo.com/pictures/picture1.jpg will be redirected to http://www.bar.com/pictures/picture1.jpg BUT users going to http://www.foo.com/movies/movie1.avi will be redirected to http://www.mymovies.com/movies/movie1.avi.

This module can be particularly useful for a new Drupal site that is being used on a domain that formerly had a traditional file structure. If you move your old site to a new domain, you can redirect traffic to your new Drupal site to the old files without breaking links to your site that might be out there on the interwebs.
