can't get iis7 to gzip font-face font files

im on a shared webhost and i only have access to the web.config file for iis7.5. javascript files and css files are gzipped, so that works, but i think that works by default because static compression is enabled in iis7.5. however, i cannot get font files to get gzipped, they are the same size when sent and the response headers dont have content-encoding: gzip. thank you for any help.

this is the web.config file:

<configuration>
<system.webServer>
    <directoryBrowse enabled="false" />
<staticContent>
    <mimeMap fileExtension=".otf" mimeType="font/opentype" />
</staticContent>
<httpCompression directory="%SystemDrive%\inetpub\temp\IIS Temporary Compressed Files">
        <scheme name="gzip" dll="%Windir%\system32\inetsrv\gzip.dll" />
        <dynamicTypes>
    <add mimeType="text/*" enabled="true" />
        <add mimeType="message/*" enabled="true" />
        <add mimeType="font/open-type" enabled="true" />
    <add mimeType="application/javascript" enabled="true" />
    <add mimeType="text/css" enabled="true" />
    <add mimeType="text/html" enabled="true" />
    <add mimeType="*/*" enabled="false" />
        </dynamicTypes>
    <staticTypes>
    <add mimeType="text/*" enabled="true" />
    <add mimeType="font/opentype" enabled="true" />
        <add mimeType="message/*" enabled="true" />
        <add mimeType="application/javascript" enabled="true" />
    <add mimeType="*/*" enabled="false" />
        </staticTypes>
</httpCompression>
    <urlCompression dynamicCompressionBeforeCache="true" doDynamicCompression="true" doStaticCompression="true" />
    <defaultDocument>
        <files>
            <clear />
            <add value="Default.htm" />
            <add value="Default.asp" />
            <add value="index.htm" />
            <add value="index.html" />
            <add value="iisstart.htm" />
            <add value="default.aspx" />
            <add value="index.php" />
        </files>
    </defaultDocument>

</system.webServer>
</configuration>

I was still having this issue despite having enabled static and dynamic compression via the IIS remote management console.

I finally managed to resolve it by changing the mime type of .tff files from application/octet-stream to font/ttf on IIS.

The important thing to note is that modifying your applicationHost.config (in %windir%\system32\inetsrv\config) from the following setting:

<section name="httpCompression" allowDefinition="AppHostOnly" overrideModeDefault="Deny" />

to:

<section name="httpCompression" overrideModeDefault="Allow" />

will enable configuration of the httpCompression tag under the system.webServer tag in your web.config.

By default IIS doesn't include those MIME Types in the httpCompression module. You need to modify your applicationHost.config file in: C:\Windows\System32\inetsrv\config.

This file will affect all your websites and must be opened with a 64-bit text editor in a 64-bit Windows. (Notepad2 64-bit, Notepad, do not use Notepad++)

<httpCompression directory="%SystemDrive%\inetpub\temp\IIS Temporary Compressed Files">
    <scheme name="gzip" dll="%Windir%\system32\inetsrv\gzip.dll" />
        <staticTypes>
            <add mimeType="text/*" enabled="true" />
            <add mimeType="message/*" enabled="true" />
            <add mimeType="application/x-javascript" enabled="true" />
            <add mimeType="application/atom+xml" enabled="true" />
            <add mimeType="application/xaml+xml" enabled="true" />
            <add mimeType="*/*" enabled="false" />

            <!-- HERE -->
            <add mimeType="image/svg+xml" enabled="true" />
            <add mimeType="application/font-woff" enabled="true" />
            <add mimeType="application/x-font-ttf" enabled="true" />
            <add mimeType="application/octet-stream" enabled="true" />
            <!-- HERE -->

        </staticTypes>
        <dynamicTypes>
            <add mimeType="text/*" enabled="true" />
            <add mimeType="message/*" enabled="true" />
            <add mimeType="application/x-javascript" enabled="true" />
            <add mimeType="*/*" enabled="false" />

            <!-- HERE -->
            <add mimeType="image/svg+xml" enabled="true" />
            <add mimeType="application/font-woff" enabled="true" />
            <add mimeType="application/x-font-ttf" enabled="true" />
            <add mimeType="application/octet-stream" enabled="true" />
            <!-- HERE -->

        </dynamicTypes>
</httpCompression>

These are my personal settings to compress SVG, WOFF, EOT and TTF files.

Then simply type iisreset in your command line to reload the config in IIS, or restart your computer.

UPDATE

Woff and Woff2 files are already compressed, so you don't need to do this. In fact, the client will lose performance if you gzip those.

If you cannot access the applicationhosts.config in all environments a more pragmatic approach is simply to implement a httpmodule for gzipping the svg files.

See this post for a code example: http://laubplusco.net/gzip-svg-files-asp-net/

The problem is that by default IIS doesn't include the mime types for the web fonts in the list of mime types that can be compressed. Javascript and css files are included which is why you are seeing them getting compressed.

Your httpCompression settings are probably not being used, those are locked by default and cannot be set in the web.config. Take a look at this page: http://support.microsoft.com/kb/969062. In the "More Information" section it says, "you can set MIME types for the web server level only."

The only way I could get this to work on my local server was to add the mime types in the httpCompression section of applicationHost.config (this requires admin access). Setting them in web.config had no affect.
