JSP 去除缓存

JSP 去掉缓存

在JSP页面的头部加上

<%    response.setHeader("Cache-Control","no-cache,post-check=0,pre-check=0");response.setHeader("Pragma","no-cache");response.setHeader("Expires","Thu,01 Dec 1994 16:00:00 GMT");response.setDateHeader("Expires", -1);%>

<meta http-equiv="pragma"? content='no-cache'>??? <meta http-equiv="Cache-Control" content='no-cache, must-revalidate'>??? <meta content="0" http-equiv="expires" >
