如何实现网页的立即失效?

2006-11-07 15:53 330 查看
我的页面希望在IE浏览的时候,无论什么时候都自动从服务器读取数据,如何实现?

<HEAD>
<META HTTP-EQUIV="Pragma" CONTENT="no-cache">
<META HTTP-EQUIV="Cache-Control" CONTENT="no-cache">
<META HTTP-EQUIV="Expires" CONTENT="0">
</HEAD>

==================================================

借花献佛:

HTM网页
<META HTTP-EQUIV="pragma" CONTENT="no-cache">
<META HTTP-EQUIV="Cache-Control" CONTENT="no-cache, must-revalidate">
<META HTTP-EQUIV="expires" CONTENT="Wed, 26 Feb 1997 08:21:57 GMT">

ASP网页
<%
  Response.Expires = -1
  Response.ExpiresAbsolute = Now() - 1
  Response.cachecontrol = "no-cache"
%>

PHP网页
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
header("Cache-Control: no-cache, must-revalidate");
header("Pragma: no-cache");

JSP
    response.setHeader("Pragma","No-Cache");
    response.setHeader("Cache-Control","No-Cache");
    response.setDateHeader("Expires", 0);

C#中禁止cache的方法!
Response.Buffer=true;
Response.ExpiresAbsolute=System.DateTime.Now.AddSeconds(-1);
Response.Expires=0;
Response.CacheControl="no-cache";
