各位好！请教在HttpWebRequest中的二级域名的Cookie发送处理问题。

GET http://www.xiaomi.com/ HTTP/1.1
Accept-Language: zh-CN,zh;q=0.8
Host: www.xiaomi.com
Cookie: userId=123456789
===============================================================================================================
【分析】：成功POST数据到小米官网后，返回的cookie有很多个的域名是： domain=account.xiaomi.com
导致了再次用HttpWebRequest去请求非account.xiaomi.com时，它只会发送这个Cookie：Cookie: userId=123456789
【当我故意设置为相同域名的url时，它就可以发送出去：】如：https://account.xiaomi.com/csdn

【问题】要怎样处理可以像浏览器那样把cookie再传过去呢？
我现在的Cookie是这样处理的：
public static CookieContainer _cookieContainer = new CookieContainer();--------------------编程问答-------------------- 【参考文章】：
.......
/// <summary>
/// 解析Cookie
/// </summary>
/// <param name="response"></param>
private void ParseCookie(HttpWebResponse response)
{
if (!IgnoreCookies)
{
string cookiesExpression = response.Headers["Set-Cookie"];
if (!string.IsNullOrEmpty(cookiesExpression))
{
Uri cookieUrl = new Uri(string.Format("{0}://{1}:{2}/",
response.ResponseUri.Scheme,
response.ResponseUri.Host,
response.ResponseUri.Port));
try
{
_cookieContainer.SetCookies(cookieUrl, cookiesExpression);
}
catch
{ }
}
}
}
/// <summary>
/// 配置请求设置
/// </summary>
/// <param name="request"></param>
private void ConfigRequest(HttpWebRequest request)
{
.....
request.CookieContainer = _cookieContainer;
....
}
