i was trying the same idea and was successfull in sending file through Post httpwebrequest. Please see the following code sample

private void ChunkRequest(string fileName,byte[] buffer)


{
//Request url, Method=post Length and data.
string requestURL = "http://localhost:63654/hello.ashx";
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(requestURL);
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";

// Chunk(buffer) is converted to Base64 string that will be convert to Bytes on the handler.
string requestParameters = @"fileName=" + fileName +
"&data=" + HttpUtility.UrlEncode( Convert.ToBase64String(buffer) );

// finally whole request will be converted to bytes that will be transferred to HttpHandler
byte[] byteData = Encoding.UTF8.GetBytes(requestParameters);

request.ContentLength = byteData.Length;

Stream writer = request.GetRequestStream();
writer.Write(byteData, 0, byteData.Length);
writer.Close();
// here we will receive the response from HttpHandler
StreamReader stIn = new StreamReader(request.GetResponse().GetResponseStream());
string strResponse = stIn.ReadToEnd();
stIn.Close();
}
