扩展IIS7支持的文件类型（转）
原文出处：http://blog.csdn.net/txz2003/archive/2009/11/06/4775513.aspx
可在虚拟目录中添加web.config文件（实际为文本文件）
文件格式如下
<configuration>
<system.webServer>
<staticContent>
<mimeMap fileExtension=".mp4" mimeType="video/mp4" />
<mimeMap fileExtension=".m4v" mimeType="video/m4v" />
</staticContent>
</system.webServer>
</configuration>
MIME类型可视情况自行更改，一并在网上搜索了常见的MIME类型列表，附后供大家参考
