Client IP adress WordPress IIS6 behind Nginx reverse proxy

Dette fungerer gjerne ikkje for alle men fungerte i mitt tilfelle med oppsett:
Nginx > Windows 2003 x64 server > IIS6 > WordPress

Løsning : client ip adress nginx > IIS6 > WordPress.

Sett denne koden inn i wp-config.php rett etter <?php

if (isset($_SERVER[‘HTTP_X_FORWARDED_FOR’])) {
$ips = explode(‘,’, $_SERVER[‘HTTP_X_FORWARDED_FOR’]);
$_SERVER[‘REMOTE_ADDR’] = $ips[0];
}
