HTTP Test



Click here for a larger image.

Environment: VS7 C# .NET

I wrote this application to see what the HttpWebRequest and HttpWebResponse classes did. I am not a Web programmer and I'm not that familiar with HTTP or HTML, so I wanted to see what these function do. I'm sure someone else who has a more intimate knowledge of these protocols could do a lot more. I was unsure of what I was seeing, which is why I wrote WebPageGet.

private void GetButtonClick(object sender, System.EventArgs e)
{
HttpWebRequest httpReq;
HttpWebResponse httpResp;
Stream httpStream;

  m_results.Text = "";
  MessageBeep(100);
try
{
  ASCIIEncoding ASCII = new ASCIIEncoding();
  byte[] buf = new byte[ 128000 ];
  m_header_list.Items.Clear();
  httpReq    = (HttpWebRequest)WebRequest.Create(m_url.Text);
  httpResp   = (HttpWebResponse)httpReq.GetResponse();
  httpStream = httpResp.GetResponseStream();
  int count  = httpStream.Read(buf, 0, buf.Length);
  httpStream.Close();

  string tempstr = ASCII.GetString(buf, 0, count);
  ChangeLfToCrLf(ref tempstr);
  m_results.Text = tempstr;
  for(int i=0; i < httpResp.Headers.Count; ++i)
    m_header_list.Items.Add( httpResp.Headers.Keys[i] + " = " 
                             + httpResp.Headers[i]);
  for(int i=0; i< httpResp.Cookies.Count; i++)
    m_cookie_list.Items.Add( httpResp.Cookies[i]);

}
catch (Exception except)
{
  m_results.Text = "Generic Exception: {0}" 
                 + except.Message.ToString();
}
  MessageBeep(10000);
}

    Tanks for useful program, but after WebRequest object is created it's necessary to initialize CookieContainer property. If it's not done, then amount of cookies will be always 0.

    Solution: After WebRequest.Create add string:
    httpReq.CookieContainer = new CookieContainer();
