httpWebRequest issue

Feb 27 2008 8:05 AM
Hello,

I hope somebody has a good explanation for this issue.

Okay I'm having troubles with the httpWebRequest method. I need to download reports from a specified server (can't give these details). Now I don't have trouble with an "HTTPS" url but I with an "HTTP" url I get the error :

error: The server committed a protocol violation. Section=ResponseHeader Detail=Header name is invalid

This the first time I got this error in c#.net. I tried this in Java and there I didn't had any problems. So I'm kind of lost.

I search the internet to see what the "ProtocolViolationException" throws. I found this on the msdn site:

ProtocolViolationException :
Method is GET or HEAD, and either ContentLength is greater or equal to zero or SendChunked is true.
-or-
KeepAlive is true, AllowWriteStreamBuffering is false, ContentLength is -1, SendChunked is false, and Method is POST or PUT.

I did an output of these properties and some how these don't have the values mention to trigger the ProtocolViolationException.

So my question is, How is this possible?

this is my testClass:

using System;
using System.Collections.Generic;
using System.Text;
using System.IO;
using System.Net;

namespace adlogix_views
{
    static class httpTestClass
    {
        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        [STAThread]
        static void Main()
        {
          
            string page = "";
            try
            {               
                // write a line of text to the file
                HttpWebRequest wr = (HttpWebRequest)WebRequest.Create("http://www.mywebsite.com");

                string userPass = "myUsername:myPassword";
                string encoding = Convert.ToBase64String(Encoding.ASCII.GetBytes(userPass));

                wr.Headers.Add("Authorization", "Basic " + encoding);
                wr.PreAuthenticate = true;

                Console.WriteLine("Method = " + wr.Method);
                Console.WriteLine("ContentLength = " + wr.ContentLength);
                Console.WriteLine("SendChunked = " + wr.SendChunked);
                Console.WriteLine("KeepAlive = " + wr.KeepAlive);
                Console.WriteLine("AllowWriteStreamBuffering = " + wr.AllowWriteStreamBuffering);

                HttpWebResponse ws = (HttpWebResponse)wr.GetResponse();
                Stream str = ws.GetResponseStream();
                StreamReader sr = new StreamReader(str);
                while ((page = sr.ReadLine()) != null)
                {
                    Console.WriteLine(page);
                }


            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }
        }
    }
}


this is the output of the properties

output: Method = GET
        ContentLength = -1
        SendChunked = False
        KeepAlive = True
        AllowWriteStreamBuffering = True


I hope somebody can help me with this.
