[转]IIS添加MIME扩展类型及常用的MIME类型列表
http://www.cr173.com/html/18997_1.html
经常我在用IIS做为下载服务器的时候有时传上去的文件比如 xxx.iso 文件名名是传上去了，但是用http打开的时候确显示为 404 文件不存在。
这其实是IIS对文件的一种保护，不在IIS指定的MIME类型里的文件显不会操作。
觉见的有 mp4 / flv / iso / 7z / apk 等扩展名的文件 iis 本身是没有指定MIME类型的，这类文件默认在IIS里是不能下载的。
我们可以打开IIS 在 xx本地服务器上 右键 -> 属性 然后在 MIME类型 中查看已经的MIME格式
比如我们需要IIS支持 MP4 文件下载可以这么设置：（这里我们对IIS全局进行设置、如果只针对某一个站点可以直接设置站点的）
1、在 网站 上右键 选属性
2、在打开的 网站 属性 上选择 HTTP 头 再点 MIME类型按钮
3、在打开的窗本中 点下 新建
4、在弹出的 MIME类型框上 扩展名 MP4 MIME类型为： application/octet-stream
这样IIS就可以支持 MP4下载了。
下面列出一些常用的 扩展名的 MIME类型。
如果不知道MIME类型 可以写通用的: application/octet-stream
还有一些规律如果是文本类的让IE可以直接打开的 MIME 可以为 text/扩展名
如果是音频打开的时候让windows自动播放的可以用 audio/扩展名
