如何清除jsp页面缓存、cookie、session？

Answer 1

一、清除页面缓存
在jsp页里：<%response.setHeader("Pragma","No-cache");
response.setHeader("Cache-Control","no-cache");
response.setDateHeader("Expires", 0);
response.flushBuffer();%
在html页里：
<meta http-equiv="Content-Type" content="text/html; charset=gb2312"
<META HTTP-EQUIV="Pragma" CONTENT="no-cache"
<META HTTP-EQUIV="Cache-Control" CONTENT="no-cache"
<META HTTP-EQUIV="Expires" CONTENT="0"
二、清除cookie<%Cookie killMyCookie = new Cookie("mycookie", null);
killMyCookie.setMaxAge(0);
killMyCookie.setPath("/");
response.addCookie(killMyCookie);%三、清除session
页面载入时清除session：
<%@ page language="java" %<%session.invalidate();%页面关闭时清除session
