	// This ajaxConnector is the base of phpFormular-Ajax functionality
	//
	// The most wanted is, that you can connect to any with method any, then you
	// can setup the readyStateChange after request and so on. It is a most
	// simple ajax-connector to be free in requesting anything over ajax.
	//

	// Example:
	//
	// URL, METHOD (get|post), TYPE (xml|empty), VALUES
	//
	// createAjaxConnect('dummy.php{$SET_SESSION_URL}', 'POST', 'xml', 'FORMULARCOMMAND_DELETE=true&fileid={$item.id}&filetype={$item.type}')
	//

	//
	// <?xml version="1.0" encoding="ISO-8859-1" ?>
	// <ajax>
	// 	<status>true</status>
	// 	<message><![CDATA[Aktion wurde ausgef?hrt]]></message>
	// 	<htmlid><![CDATA[main]]></htmlid>
	// 	<htmlcode><![CDATA[<strong>Hau mich blau und irgendein HTML-Konstrukt welchen man dann auf der Webseite im HTML-Element "htmlid" austauscht</strong>]]></htmlcode>
