How do I disable caching of an individual file in IIS 7 using weserver config settings

Is there any way to diable the caching of a single javascript file in my ASP.NET applicaiton without disabling the caching of any other files in the application?

It is running on IIS 7 in Azure, so to me it seems that my only options of controlling this are within the webserver tags.

I currently use the folowwing config, but this is disabling cache on all files.

     <modules runAllManagedModulesForAllRequests="true"/>

    <staticContent>
      <clientCache cacheControlMode="DisableCache"/>
    </staticContent>

  </system.webServer>

I just want to disable cache of a single javascript file that changes quite often.

Is it possible?

I 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]

Looks like the above answer is missing a "profiles" tag

<caching>
  <profiles>
    <add extension=".js" kernelCachePolicy="DontCache" policy="DontCache"/>
  </profiles>
</caching>
