    'Create a web request for "www.msn.com".
    Dim myHttpWebRequest As HttpWebRequest = CType(WebRequest.Create("http://www.msn.com"), HttpWebRequest)
myHttpWebRequest.Timeout = 1000
    'Get the associated response for the above request.
    Dim myHttpWebResponse As HttpWebResponse = CType(myHttpWebRequest.GetResponse(), HttpWebResponse)
    
    'Get the headers associated with the response.
    Dim myWebHeaderCollection As WebHeaderCollection = myHttpWebResponse.Headers
    Dim i As Integer
    For i = 0 To myWebHeaderCollection.Count - 1
        Dim header As [String] = myWebHeaderCollection.GetKey(i)
        Dim values As [String]() = myWebHeaderCollection.GetValues(header)
        If values.Length > 0 Then
            Console.WriteLine("The values of {0} header are : ", header)
            Dim j As Integer
            For j = 0 To values.Length - 1
                Console.WriteLine(ControlChars.Tab + "{0}", values(j))
            Next j
        Else
            Console.WriteLine("There is no value associated with the header")
        End If
    Next i 

// Create a web request for "www.msn.com".
HttpWebRequest myHttpWebRequest = (HttpWebRequest)(
    WebRequest.Create("http://www.msn.com"));
myHttpWebRequest.set_Timeout(1000);
// Get the associated response for the above request.
HttpWebResponse myHttpWebResponse = (HttpWebResponse)(
    myHttpWebRequest.GetResponse());
// Get the headers associated with the response.
WebHeaderCollection myWebHeaderCollection = myHttpWebResponse.
    get_Headers();

for (int i = 0; i < myWebHeaderCollection.get_Count(); i++) {
    String header = myWebHeaderCollection.GetKey(i);
    String values[] = myWebHeaderCollection.GetValues(header);
    if (values.get_Length() > 0) {
        Console.WriteLine("The values of {0} header are : ", header);
        for (int j = 0; j < values.get_Length(); j++) {
            Console.WriteLine("\t{0}", values.get_Item(j));
        }
    }
    else {
        Console.WriteLine("There is no value associated with the" 
            + " header");
    }
}
myHttpWebResponse.Close();
