我在一个站点上挂了百度统计的代码，如下：

<script type="text/javascript">
var _bdhmProtocol = (("https:" == document.location.protocol) ? " https://" : " http://");
document.write(unescape("%3Cscript src='" + _bdhmProtocol + "hm.baidu.com/h.js%3F84ed2e6f46b9d9bfdc018744dc663e07' type='text/javascript'%3E%3C/script%3E"));
</script>

有一行js代码用于请求下面的js页
http://hm.baidu.com/h.js?84ed2e6f46b9d9bfdc018744dc663e07

我想看下这个js页的内容，但是打开该链接之后啥也看不到，怎么回事儿？浏览器怎么执行这个js页？

你自己看吧 这个那个文件里的所有内容
