页面清除缓存

html-cache.html
content_copyfile_download
<!--如果需要在html页面上设置不缓存，这在<head>标签中加入如下语句：-->
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">

A_Cache.java
content_copyfile_download
//在springmvc中最直接的方法是设置HttpServletResponse的“Cache-contorl”属性
//http1.0
getResponse().setHeader("Pragma", "no-cache");
getResponse().setDateHeader("Expires", 0);
//http1.1
getResponse().addHeader("Cache-Control", "no-cache no-store");
