IIS ignores system.webServer staticContent section

UDPATE

On a whim, I decided to upload the 4 fonts files to an font converter. I converted the fontsfrom ttf to ttf and then tried it. Everything works fine: the Content-Type is set correctly and the X-Powered-By header is removed.

Weird.

I am trying to change the mime type (Content Type header) of a .ttf file in web.config on IIS7.

Here is the staticContent section inside <system.webServer />:

<staticContent>
    <remove fileExtension=".ttf" />
    <mimeMap fileExtension=".ttf" mimeType="font/ttf" />
</staticContent>

Even with the above configuration all .ttf files are sent with application/octetstream.

I also have a customHeader section with the following:

<remove name="X-Powered-By" />

which successfully removes the X-Powered-By header for css, png, jpg, gif, ico, .aspx, .htm, .html, shtml, and js files. It does NOT, however, work for .ttf.

Anyone know what I'm doing wrong?

My entire web.config just in case:

The fix was to set runAllManagedModulesForAllRequests to true.

<system.webServer>
    <modules runAllManagedModulesForAllRequests="true">
        <!-- stuff -->
    </modules>
</system.webServer>
