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
