在开启iis gzip功能后可以为服务器节省一些宽度哦，下面是iis实现的方法 代码如下。

下面看一下iis7下 js文件启用gzip压缩
iis7已经启用静态文件压缩（gzip）但是死活不压缩，查找后发现是ii7下mime类型设置问题
将.js的mime类型设置为application/网页特效
再查看页面，已经启用了gzip。
不过，几个天后又发现有的js文件被压缩，有的却没有
查找原因发现是引用js文件是没有设置type
<script></script>
<script src=”a.js”></script>
加上type="text/javascript"类型后问题解决。
iis7中启用js压缩的方法
先打开iis管理，选择我要设置的站点，然后在右边的功能区找到mime types看看里面是否有.js的选项，如果没有可以手功加上
有的话把.js的值设置成：application/x-javascript记住不能少并x-有的网友介绍是application/javascript
偶在win2008+iis7下试过，如果不加x-也是不会压缩的。
当然最好在上传js前对js进行一次压缩这样效果会更好啦。 可以到网上找找tbcompressor工具，这个工具压缩不错
只不过需要你的js写的标准，不然会出错，分析不了你的js语法就压缩不了
