connectionexception

I am developing an C# application which logs data from a webserver. It sends the following post request to the webserver and awaits for the response. /// <summary> /// Function for obtaining testCgi data /// </summary> /// <param name="Parameters"></param> /// <returns></returns> private string HttpmyPost(string Parameters) { string str = "No response"; HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uriTestCGI); request.Method = "POST"; byte[] bytes = Encoding.UTF8.GetBytes(Parameters); request.ContentLength = bytes.Length; Stream requestStream = request.GetRequestStream();
