The underlying connection was closed....

Question

Hi all,

               Error :

The underlying connection was closed a connection that was expected to be kept alive was closed by the server 

 

 I'm using window form application and use API with Basic authentication, if I continue sending a 4-5 request to the server I again send request after 10-15 seconds then raised the issue. My Code here.

 

 

HttpWebRequest req = (HttpWebRequest)(HttpWebRequest.Create(URL));

req.Method = "POST";

req.ProtocolVersion = HttpVersion.Version10;

req.ContentType = "application/xml";

req.Timeout = ResponseTimeOut;

req.KeepAlive = false;

req.Headers.Set(HttpRequestHeader.Authorization, "Basic dshgfhjhgdshjsdhh==");

d1 = DateTime.Now;

string content = authXMLString;

req.ContentLength = content.Length;

Stream wri = req.GetRequestStream();

byte[] array = Encoding.UTF8.GetBytes(content);

wri.Write(array, 0, array.Length);

wri.Flush();

wri.Close();

HttpWebResponse HttpWResp = (HttpWebResponse)req.GetResponse();

int resCode = (int)HttpWResp.StatusCode;

StreamReader reader = new StreamReader(HttpWResp.GetResponseStream(), System.Text.Encoding.UTF8);

string resultData = reader.ReadToEnd();

d2 = DateTime.Now;

decodedresult = resultData;

decodedresult = decodedresult.Replace("<", "<");

decodedresult = decodedresult.Replace(">", ">");
