Using System.IO;
    
Using System.Threading;  namespace WebServer {public partial class HttpDemo:System.Web.UI.Page {protected void Page_Load (object
    
            sender, EventArgs e) {//stop for 3 seconds to facilitate the test of cancellation of HTTP request Thread.Sleep (3000);
    
            var action = request.querystring["Action"]; Switch (action) {case "getString"://Response HTTP GET string Response.Write (
