Handllling Cookie

Question

Hi all,
        I am new to .net. I want to log in to a web site(PHP) problematically and update and read my data. I am usingSystem.Net.CookieContainer to maintain cookies. What I am doing is sending back that cookies comes with responds. I am getting time-out errors. There are two domain names in inside of the object(one with a prefix of "." eg: www.test.te and www.test.te). Here is my coding.

 

Stream os = null;
            try
            { // send the Post
                webRequest.ContentLength = bytes.Length;   //Count bytes to send
                os = webRequest.GetRequestStream();
                os.Write(bytes, 0, bytes.Length);         //Send it
            }
            catch (WebException ex)
            {
                //ex.Message = "Failed to send data to "+url+". Because " + ex.Message;
                throw ex;
            }
            finally
            {
                if (os != null)
                {
                    os.Close();
                }
            }

            try
            { // get the response
                HttpWebResponse webResponse = (HttpWebResponse)webRequest.GetResponse();
                if (webResponse == null)
                { return null; }
                StreamReader sr = new StreamReader(webResponse.GetResponseStream());
                MyWebInfo.CookiesContainer.Add(webResponse.Cookies);
                return sr.ReadToEnd().Trim();

I set 

MyWebInfo.CookiesContainer

 as cookie container as next request

webRequest.ContentType = "application/x-www-form-urlencoded";
            webRequest.Method = "POST";
            // webRequest.CookieContainer = new CookieContainer();
            webRequest.CookieContainer = MyWebInfo.CookiesContainer;
            byte[] bytes = Encoding.ASCII.GetBytes(parameters);

It is not working properly. If some one can tell me the correct way it is a great help. I tried to do then for a long time
Thanks in advance
