IIS7禁用单个静态文件的缓存配置方法

IIS7中，想将一个经常修改的静态文件设置为不可缓存，在IIS配置界面里怎么也找不到...

一番google之后在stackoverflow里边发现了这样一段回答，最终解决了问题：

 just stumbled across this question; you can use the following to disable the cache on a specific file:

<configuration>
  <location path="path/to/the/file">
    <system.webServer>
      <staticContent>
        <clientCache cacheControlMode="DisableCache" />
      </staticContent>
    </system.webServer>
  </location>
</configuration>
(Note that the path is relative to the web.config file)

Alternatively, place the single file in a directory on it's own, and give that directory it's own web.config that disables caching for everything in it;

<configuration>
  <system.webServer>
    <httpProtocol>
      <customHeaders>
        <add name="Cache-Control" value="no-cache" />
      </customHeaders>
    </httpProtocol>
  </system.webServer>
</configuration>
[Both tested on IIS7.5 on Windows 7, but you'll have to confirm that it works OK on Azure]

按照回答中的方法在web.config里边进行配置，再访问，在header里边就可以看到

Cache-Control:no-cache

了，证明配置生效~
