Dim objXmlHttp
Dim strHTML

Set objXmlHttp = Server.CreateObject("Msxml2.ServerXMLHTTP")

objXmlHttp.open "GET","http://website1.com/test?Success=http://www.success.com&Failure=http://www.failure.com", False

Simple way would be to use same COM in .net
In VS.NET, add reference to "Microsoft XML version 2.0"

Then write this code:

MSXML.XMLHTTPRequestClass objXmlHttp  = new MSXML.XMLHTTPRequestClass();
objXmlHttp.open("GET","http://website1.com/test?Success=http://www.success.com&Failure=http://www.failure.com", false, null, null);
string body = null;
objXmlHttp.send(body);
string strHTML = objXmlHttp.responseText;

Cheers,
S Sansanwal

OK, I'm trying to implement your suggestion.

First of all, you mention adding a reference to:
     "Microsoft XML version 2.0"
I see
     "Microsoft XML, v2.6"

Presumably that's OK?

Secondly, it doesn't compile.  I get this error message:

c:\inetpub\wwwroot\WebApplication1\WebForm1.aspx.cs(25): The type or namespace name 'MSXML' could not be found (are you missing a using directive or an assembly reference?)

Am I missing a "using"?  I have yet to figure out a reliable way of determining what "using" I am missing.

That's as far as I can go with your suggestion.

if your doing xml stuff try this code

try
                  {

                        XmlTextReader r = new XmlTextReader("http://www.w3schools.com/xml/note.xml");                  
                        XmlDocument d = new XmlDocument();
                        d.Load(r);                              
                        XmlNode node = d.SelectSingleNode("/note/to");                  
                        if (node!=null) MessageBox.Show(node.InnerText);
                        r.Close();
                  }
                  catch(System.Net.WebException ex)
                  {
                        MessageBox.Show("Web exception  :"+ex.Message);
                  }
                  catch(System.Xml.XmlException ex)
                  {
                        MessageBox.Show("Xml exception :"+ex.Message);
                  }
                  catch(System.Exception ex)
                  {
                        MessageBox.Show("General exception :"+ex.Message);
                  }


but i think you just want some data read from a page,.. so here :

HttpWebRequest HttpWReq =
                        (HttpWebRequest)WebRequest.Create("http://"+textBox1.Text);

                  HttpWebResponse HttpWResp = (HttpWebResponse)HttpWReq.GetResponse();
                  
                  Stream receiveStream = HttpWResp.GetResponseStream();
                  System.Text.Encoding encode = System.Text.Encoding.GetEncoding("utf-8");
                  // Pipes the stream to a higher level stream reader with the required encoding format.
                  StreamReader readStream = new StreamReader( receiveStream, encode );
                  textBox2.Text = "\r\nResponse stream received.\r\n";
                  Char[] read = new Char[256];
                  // Reads 256 characters at a time.    
                  int count = readStream.Read( read, 0, 256 );
                  textBox2.Text += "HTML...\r\n";
                  while (count > 0)
                  {
                        // Dumps the 256 characters on a string and displays the string to the console.
                        String str = new String(read, 0, count);
                        textBox2.Text += str;
                        count = readStream.Read(read, 0, 256);
                  }
                  


                  HttpWResp.Close();
