	//第一种方法，Global文件重写-只能处理aspx,ascx等几种文件，不支持html等为后缀的文件请求
	 protected void Application_Start(object sender, EventArgs e)
	 {
	 File.AppendAllText(Server.MapPath("global.txt"),DateTime.Now.ToString()+" AppStart\r\n");
	 }
	 protected void Session_Start(object sender, EventArgs e)
	 {
	 File.AppendAllText(Server.MapPath("global.txt"), DateTime.Now.ToString()+" ip:"+Request.UserHostAddress+ " SessionStart \r\n");
	 }
	 protected void Application_BeginRequest(object sender, EventArgs e)
	 {
	 //每次打开网页都会发生
	 //File.AppendAllText(Server.MapPath("global.txt"), DateTime.Now.ToString() + " ip:" + Request.UserHostAddress + "request\r\n");
	 ////可以用来屏蔽指定ip
	 //if (HttpContext.Current.Request.UserHostAddress == "127.0.0.1")
	 //{
	 // HttpContext.Current.Response.Write("已被屏蔽");
	 // HttpContext.Current.Response.End();
	 //}
	 //防止图片盗链
	 if (HttpContext.Current.Request.Url.AbsolutePath.EndsWith(".jpg") && HttpContext.Current.Request.UrlReferrer.Host != "localhost")
	 {
	 //Context.Response.Write(HttpContext.Current.Request.UrlReferrer.Host);
	 HttpContext.Current.Response.WriteFile( HttpContext.Current.Server.MapPath("~/dl.jpg"));
	 HttpContext.Current.Response.End();
	 }
	 //符合格式时，内部重写，地址栏不显示此地址
	 Regex reg = new Regex(@".+MyStatic-(\d+).aspx");
	 var match = reg.Match(HttpContext.Current.Request.Url.AbsolutePath);
	 if(match.Success)
	 {
	 string page=match.Groups[1].Value;
	 //仿静态页面
	 HttpContext.Current.RewritePath("~/MyStatic.aspx?page="+page);
	 }
	
	 }
	 protected void Application_AuthenticateRequest(object sender, EventArgs e)
	 {
	 }
	 protected void Application_Error(object sender, EventArgs e)
	 {
	 //获取未处理的异常信息
	 Exception t = HttpContext.Current.Server.GetLastError();
	 File.AppendAllText(Server.MapPath("global.txt"), DateTime.Now.ToString() +t.Message+"服务器错误\r\n");
	 }
	 protected void Session_End(object sender, EventArgs e)
	 {
	 File.AppendAllText(Server.MapPath("global.txt"), DateTime.Now.ToString() + " ip:" + Request.UserHostAddress + " SessionEnd \r\n");
	 }
	 protected void Application_End(object sender, EventArgs e)
	 {
	 File.AppendAllText(Server.MapPath("global.txt"), DateTime.Now.ToString() + " AppEnd\r\n");
	 }
