HttpWebRequest does not handle redirect!!

[Jon Davis]

I have an HttpWebRequest object that is performing an HTTP POST query on an
HTTP server that is returning the proper status code of either 301 or 303
(redirect) and a Location header, but the HttpWebRequest object isn't
following it and is returning the full body of the initial HTTP response
instead. AllowAutoRedirect defaults to True, but setting it to True doesn't
help.

What's the deal?

// XML-RPC Client
public object Call(Uri uri, string Method, params object[] Params) {
// build and send request
HttpWebRequest req =
(HttpWebRequest)WebRequest.Create(uri);
req.Proxy = ProxySettings;
req.CookieContainer = Cookies;
for (int i=0;i<Certificates.Count;i++) {
req.ClientCertificates.Add(Certificates);
}
req.ContentType = "text/xml";
req.Method = "POST";
req.UserAgent = UserAgent;
for (int i=0;i<Headers.Count;i++) {
req.Headers.Add(Headers);
}
string reqBody = BuildRequest(Method, Params, Encoding);
System.Text.UTF8Encoding encoding = new UTF8Encoding();
byte[] byteReqBody=encoding.GetBytes(reqBody);
req.ContentLength = byteReqBody.Length;
Stream st;
WebResponse wr;
StreamReader sr;
try {
st = req.GetRequestStream();
} catch (Exception ex) {
throw new XmlRpcConnectException(ex.Message, ex);
}
st.Write(byteReqBody, 0, byteReqBody.Length);
st.Flush();
// receive and parse response
wr = req.GetResponse();
sr = new StreamReader(wr.GetResponseStream());
string resp = sr.ReadToEnd();
try { sr.Close();} catch {}
try {wr.Close();} catch {}
try {st.Close();} catch {}
return XmlRpcTools.ConvertElement(ParseResponse(resp), false);

}

Try looking at:
MaximumAutomaticRedirections method property --sets the maximum number of
redirections for the request to follow
