Extensions can register foreign module sources here. The default "local" source for modules from the local wiki is not set in this array. Instead that one is defined by ResourceLoader::__construct() so that it cannot be unset or overwritten.

Ejemplo:

$wgResourceLoaderSources['foo'] = array(
    'loadScript' => 'http://example.org/w/load.php',
    'apiScript' => 'http://example.org/w/api.php'
);
