1. 一种解决方法设置每次清楚浏览的页面。
In IE7, go to Tools | Internet Options. Click the Browsing History "Settings" button. Check for newer versions of stored pages: and select "Everytime I visit the page".
2. 设置访问页面的过期日期
response.setHeader ("Pragma", "No-Cache"); response.setHeader ("Cache-Control", "No-Cache"); response.setDateHeader ("Expires", 0);
