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">

<%
response.setHeader("Cache-Control","no-store");
response.setHeader("Pragrma","no-cache");
response.setDateHeader("Expires",0);
%>
