asp.net页面缓存学习

  一个小练习,学习缓存,在页面建一个按键,打印出当前时间,

在页面加上

<%@ OutputCache  Duration="15"  VaryByParam ="none" %>这行代码,
Duration是注明缓存页面的时间,15秒,VarByParam="none",这行代码的意思是,缓存不加任何条件,这样页面,在15秒内就不会再提交了!
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm8.aspx.cs" Inherits="WebApplication1.WebForm8" %>

<%@ OutputCache  Duration="15"  VaryByParam ="none" %>



<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">



<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

    <title></title>

</head>

<body>

    <form id="form1" runat="server">

    <div>

        <asp:Label ID="Label1" runat="server" Text=""></asp:Label> 

        <asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click" />

    </div>

    </form>

</body>

</html>

后台代码

public partial class WebForm8 : System.Web.UI.Page

    {

        protected void Page_Load(object sender, EventArgs e)

        {



        }



        protected void Button1_Click(object sender, EventArgs e)

        {

            DateTime  datetime = DateTime.Now;



            Label1.Text = datetime.ToString();

        }

    }
