my Request:

HttpWebRequest WebReq = (HttpWebRequest)WebRequest.Create(requestendpoint);

// Set the Headers

WebReq.Method = "POST";

WebReq.Headers.Add("Authorization", authorisation);

WebReq.Headers.Add("Cache-Control", "no-cache");

WebReq.ContentLength = msg.Length;

WebReq.Date = dateValue; // use datetime value GMT time
