浏览器缓存机制，其实主要就是HTTP协议定义的缓存机制（如： Expires； Cache-control等）。但是也有非HTTP协议定义的缓存机制，如使用HTML Meta 标签，Web开发者可以在HTML页面的<head>节点中加入<meta>标签，代码如下：
?
1
2
3
4
5
6
7
<!-- HTTP 1.1 -->
<meta http-equiv="pragma" content="no-cache">
<!-- HTTP 1.0 -->
<meta http-equiv="cache-control" content="no-cache">
<!-- Prevent caching at the proxy server -->
<meta http-equiv="expires" content="0">
<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE9" />
