I am trying to send JSON Object to Server for data synchronization. This JSON object contain non-synchronized images and their data.

Real problem is not with he JSON or the Synchronization code. But it is with the size of the Request i am sending to the server. if the size cross the limit 1.1MB then i Got this message

The remote server returned an error: (413) Request Entity Too Large.

Every this is working fine for smaller size. but it give exception error when size cross 1.1MB.

    {
        string result ="false";

        if (poststring.ToLower() == "empty")
        {
            result = "empty";
            return result;
        }

        try
        {
            ASCIIEncoding encoding = new ASCIIEncoding();
            string postData = poststring;
            byte[] data = encoding.GetBytes(postData);


            WebRequest request = WebRequest.Create("http://blunor.com/dark/data.php");
            request.Method = "POST";
            request.ContentType = "application/x-www-form-urlencoded";
            request.Credentials = CredentialCache.DefaultCredentials;
            request.ContentLength = data.Length;

            Stream stream = request.GetRequestStream();
            showMessageBox(data.Length.ToString(), "Message", 1);
            stream.Write(data, 0, data.Length);
            stream.Close();

            WebResponse response = request.GetResponse();
            stream = response.GetResponseStream();

            StreamReader sr = new StreamReader(stream);

            // this block of code check if response is +ve or negtive..
            string res_num = sr.ReadToEnd();

                if (res_num == "1")
                {
                    result = "true";
                }
                else
                {
                    result = "false";
                }
            //block end here.....

            sr.Close();
            stream.Close();

            return result;


        }
        catch (Exception ex)
        {
            MessageBox.Show("Error : " + ex.Message);
        }
        return result;
