// Add the prefixes.
foreach (string s in prefixes)
{
listener.Prefixes.Add(s);
}
listener.Start();
Console.WriteLine("Listening...");
// Note: The GetContext method blocks while waiting for a request.
HttpListenerContext context = listener.GetContext();
HttpListenerRequest request = context.Request;
// This application sends a cookie to the client marking the time
// they visited.
Cookie timeStampCookie = new Cookie("VisitDate", DateTime.Now.ToString());
// Obtain a response object.
HttpListenerResponse response = context.Response;

' Add the prefixes
For Each s As String In prefixes
listener.Prefixes.Add(s)
Next
listener.Start()
