Ein kleines Plugin, um alle Downloads mittels WordPress Download Monitor 3 an den CDN Host umzuleiten, indem vor dem Download die URL on-the-fly geändert wird.

Notwendige Anpassungen

Der Aufruf der Aktion download_ready_to_start muss in der Datei plugins/download-monitor/download.php vor die Auswahl des Mirrors verschoben werden:

$wpdb->query( $wpdb->prepare( "INSERT INTO $wp_dlm_db_log (download_id, user_id, date, ip_address) VALUES (%s, %s, %s, %s);", $d->id, $user, date("Y-m-d H:i:s" ,$timestamp), $ipAddress ) );
}

/* Do action - should allow custom functions to allow/disallow the download */
do_action('download_ready_to_start', $d);

// Select a mirror
$mirrors = trim($d->mirrors);

Der Hostname ist direkt im Plugin anzupassen ($cdn_host).
