客戶端
    xmlHttp = null;
    if (window.XMLHttpRequest) {
        // If IE7, Mozilla, Safari, and so on: Use native object.
        xmlHttp = new XMLHttpRequest();
    }
    else {
        if (window.ActiveXObject) {
            // ...otherwise, use the ActiveX control for IE5.x and IE6.
            xmlHttp = new ActiveXObject('MSXML2.XMLHTTP.3.0');
        }
    }
    xmlHttp.open("POST", strUrl, false);
    xmlHttp.send(xmlParamString);


伺服器端，ASP.net程式碼
                XmlDocument doc = new XmlDocument();
                doc.Load(Request.InputStream);

如果用Web服務，可以按字串引數方式定義
