HTML缓存设置

1，HTML页面上设置缓存头：

<meta http-equiv="Expires" content="0">
<meta http-equiv="Pragma" content="no-cache">
<meta http-equiv="Cache-control" content="no-cache">
<meta http-equiv="Cache" content="no-cache">

2，后台java设置响应头

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