HttpWebRequest僅發送Get請求，而不發布

Question

我試圖使用HttpWebRequest發送POST請求，而小提琴手告訴我我正在發送GET嗎？ 任何幫助將不勝感激，因為我能夠看到自己做錯了什么。

代碼：

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(LOGIN_API_BASE_URL);
        string postString = string.Format("api_email={0}&api_password={1}", EMAIL, PASSWORD);
        ASCIIEncoding encoding = new ASCIIEncoding();
        byte[] data = encoding.GetBytes(postString);
        CookieContainer cookies = new CookieContainer();
        request.CookieContainer = cookies;
        //request.AllowWriteStreamBuffering = true;
        request.Method = "POST";
        request.ContentType = "application/x-www-form-urlencoded";
        request.ContentLength = data.Length;
        request.Timeout = i_timeout;
        //request.UserAgent = "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.1) Gecko/2008070208 Firefox/3.0.1";
        //request.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";
        //request.Referer = "https://accounts.craigslist.org";

        using (Stream writer  = request.GetRequestStream())
        {
            writer.Write(data, 0, data.Length);
            //writer.Close();
        }

        StreamReader responseReader = new StreamReader(request.GetResponse().GetResponseStream());
        string responseData = responseReader.ReadToEnd();

        responseReader.Close();
        request.GetResponse().Close();

確定發現了問題，將請求發送到的網址是http://domain.com ，當我將其發送到http://www.domain.com時，它可以工作並發送帖子。 那么新的問題是為什么呢？ （由於我不喜歡自己投票，因此答案將得到我問題的答案）
