c# - C#发送POST请求并接收303状态码

我正在写一个简单的应用程序，它连接到网页并从文档的正文接收特定的数据。
我用这种方式发送HttpWebRequest：

HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://webpage.com/page1.php");
request.Method = "POST";
string postData = "some_post_data";
byte[] byteArray = Encoding.UTF8.GetBytes(postData);
request.ContentType = "application/x-www-form-urlencoded";
request.Referer = "http://webpage.com/";
request.ContentLength = byteArray.Length;
request.CookieContainer = new CookieContainer();
request.UserAgent = "Mozilla/5.0 (Windows NT 6.2; WOW64) AppleWebKit/537.31 (KHTML, like Gecko) Chrome/26.0.1410.64 Safari/537.31";
request.Headers.Add("Cookie", string.Format("sess_id={0}", UserInfo.SessionId));
request.Headers.Add("Accept-Charset", "ISO-8859-2,utf-8;q=0.7,*;q=0.3");
request.Headers.Add("Accept-Language", "pl-PL,pl;q=0.8,en-US;q=0.6,en;q=0.4");
request.Headers.Add("Accept-Encoding", "gzip");
request.AutomaticDecompression = DecompressionMethods.GZip;

Stream dataStream = request.GetRequestStream();
dataStream.Write(byteArray, 0, byteArray.Length);
dataStream.Close(); // *** [1] ***

HttpWebResponse response = (HttpWebResponse)request.GetResponse(); // *** [2] ***
dataStream = response.GetResponseStream();
response.Close();

StreamReader reader = new StreamReader(dataStream);
string responseFromServer = reader.ReadToEnd();

好的！请求没问题，没有什么神奇的。关键是，在dataStream.Close();（第[1]行）之后，我收到303个状态代码，这意味着将重定向到另一个页面。当我阅读第[2]点的回复时，我看到了新的（重定向的）页面。
我只想在重定向前阅读标题。有可能吗？

最佳答案

在调用AllowAutoRedirect之前，将request的false属性设置为GetResponse。

request.AllowAutoRedirect = false;
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
