禁止服务器端缓存：Response.Expires = 0 或<meta http-equiv="Expires" CONTENT="0"> 禁用客户端缓存。
HTM网页
<META HTTP-EQUIV="pragma" CONTENT="no-cache">
<META HTTP-EQUIV="Cache-Control" CONTENT="no-cache, must-revalidate">
<META HTTP-EQUIV="expires" CONTENT="Wed, 26 Feb 1997 08:21:57 GMT">
ASP网页
<%
Response.Expires = -1
Response.ExpiresAbsolute = Now() - 1
Response.cachecontrol = "no-cache"
%>
PHP网页
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
header("Cache-Control: no-cache, must-revalidate");
header("Pragma: no-cache");

response.setHeader("Pragma","No-Cache");
response.setHeader("Cache-Control","No-Cache");
response.setDateHeader("Expires", 0);
