    {
            var oXMLHTTP = new ActiveXObject("Microsoft.XMLHTTP");
            var sURL = strUrl
            oXMLHTTP.open("POST", sURL, false);
            oXMLHTTP.send();
            
            objXML=oXMLHTTP.responseXML
            if(responseType.toLowerCase() == 'xml')
                return oXMLHTTP.responseXML;
            else
                return oXMLHTTP.responseText;
