你可以这样做你的JSP到阻止缓存，无法以编程方式清除缓存：
You can do this way in your JSP to prevent from caching,not able to clear the cache programatically:
<% response.setHeader("Cache-Control","no-cache"); //HTTP 1.1
response.setHeader("Pragma","no-cache"); //HTTP 1.0
response.setDateHeader ("Expires", 0); //prevents caching at the proxy server
%>
