设置ASP.NET页面不被缓存(客户端/服务器端取消缓存方法)
代码如下:
/// <summary>
/// 设置页面不被缓存
/// </summary>
private void SetPageNoCache()
{
Response.Buffer = true;
Response.ExpiresAbsolute = System.DateTime.Now.AddSeconds(-1);
Response.Expires = 0;
Response.CacheControl = "no-cache";
Response.AppendHeader("Pragma", "No-Cache");
} 1、取消缓存
(2)客户端取消
代码如下:
<html> <head> <meta http-equiv="Expires" CONTENT="0"> <meta http-equiv="Cache-Control" CONTENT="no-cache"> <meta http-equiv="Pragma" CONTENT="no-cache"> </head>
(3)服务器具端取消:
服务器端:
代码如下:
Response.Buffer = true; Response.ExpiresAbsolute = DateTime.Now.AddDays(-1); Response.Cache.SetExpires(DateTime.Now.AddDays(-1)); Response.Expires = 0; Response.CacheControl = "no-cache"; Response.Cache.SetNoStore();
Global里面:
代码如下:
protected void Application_BeginRequest(Object sender, EventArgs e)
{
HttpContext.Current.Response.Cache.SetNoStore();
}
<%@ OutPutCache Location="None"%> 页面基类:
代码如下:
public class PageBase : Page
{
public PageBase() {}
protected override OnLoad( EventArgs e ) {
Response.Cache.SetNoStore();
base.OnLoad();
}
} 最简单的办法 :-)
学CSDN的这个论坛,在URL后面随机的加一些没用的参数,比如:
http://xxx/xxx/xxx.jpg?p=xxx
IE是用过URL来控制缓存的,这样就解决了
