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
