让html以及jsp页面不被缓存

对于HTM网页，加入：
<meta HTTP-EQUIV="pragma" CONTENT="no-cache">
<meta HTTP-EQUIV="Cache-Control" CONTENT="no-cache, must-revalidate">
<meta HTTP-EQUIV="expires" CONTENT="0">
然后，jsp页面中加入：
<%
     response.setHeader("Cache-Control","no-store");
     response.setHeader("Pragrma","no-cache");
     response.setDateHeader("Expires",0);
%>
