<?php
    public static function ajax($options = array(), $xhr = null)

ajax uses the super-global variable $_SERVER which is generally not recommended.

    {
        $options    = array_merge(self::$ajaxSettings, $options);
        $documentID = isset($options['document']) ? self::getDocumentID($options['document'])
            : null;
        if ($xhr) {
            // reuse existing XHR object, but clean it up
            $client = $xhr;
            //			$client->setParameterPost(null);
