response记录

       
用这个停止jsp下面代码继续使用。
response.getWriter().close();


去除页面缓存
response.setHeader("Cache-Control","no-store");
response.setHeader("Pragrma","no-cache");
response.setDateHeader("Expires",0);


=========cookies使用
    Cookie[] cookies = request.getCookies();
    if (cookies != null) {
        for (int i = 0; i < cookies.length; i++) {
            sCookie = cookies[i];
            sname = sCookie.getName(); 
            value = sCookie.getValue();
            value = URLDecoder.decode(value , "UTF-8");
        }
    }
