Displays the Drupal administration interface in an overlay.

Code

function overlay_drupal_goto_alter(&$path, &$options, &$http_response_code) {

    // The authorize.php script bootstraps Drupal to a very low level, where
    // the PHP code that is necessary to close the overlay properly will not be
    // loaded. Therefore, if we are redirecting to authorize.php inside the
    // overlay, instead redirect back to the current page with instructions to
    // close the overlay there before redirecting to the final destination; see
    // overlay_init().
