测试Http代理是否正常工作

如果是http验证，就向代理发个request，看看有没有反应！
HttpWebRequest objHttpRequest;
HttpWebResponse objResponse;
WebProxy objProxy;

objHttpRequest=(HttpWebRequest)WebRequest.Create(m_strUrl);
objHttpRequest.Timeout=3000;
objHttpRequest.AllowAutoRedirect=true;
objHttpRequest.ContentType="application/x-www-form-Urlencoded";

objProxy=new WebProxy(ProxyName,PortID);
objProxy.BypassProxyOnLocal=true;
objProxy.Credentials=new NetworkCredential(UserID,Pwd,Domain);

objHttpRequest.Proxy=objProxy;
try
{
objResponse=(HttpWebResponse)objHttpRequest.GetResponse();
}
catch(Exception e)
{
throw e;
}

scoket我就没写过啦！！
