先添加引用－COM－Microsoft Xml 3.0：
<![CDATA[using MSXML2;
]]>下面就是主要的代码：
<![CDATA[private void Page_Load(object sender, System.EventArgs e)

string Url = "<font face="Verdana"><a href="http://www.baidu.com/img/logo-yy.gif" target="_blank" rel="nofollow">http://www.baidu.com/img/logo-yy.gif</a></font>";<br>
string StringFileName = Url.Substring(Url.LastIndexOf("/") + 1);<br>
string StringFilePath = Request.PhysicalApplicationPath;<br>
if(!StringFilePath.EndsWith("/")) StringFilePath += "/";<br>
MSXML2.XMLHTTP _xmlhttp = new MSXML2.XMLHTTPClass();<br>
_xmlhttp.open("GET",Url,false,null,null);<br>
_xmlhttp.send("");<br>
