Hello, I've created functionality to allow the requests to internal paths to be redirected to the corresponding alias using Apache directives. This allows the redirects to be handled by Apache instead of requiring PHP load and Drupal to bootstrap.

The way it works is on cron internal paths and aliases are dumped into a text file parse-able by Apache's RewriteMap directive. A change to the Apache server or virtual host configuration is required to utilize the map and the appropriate rewrite occurs in the site's .htaccess file. If someone could take a look and provide feedback, I'd appreciate it.

For now I've developed as a separate module and the sandbox can be found at https://drupal.org/sandbox/bmoresafety20/1916570. With a small amount of effort it could be rolled into the Global Redirect module if suitable.
