Apache .htaccess : serve precompressed #font-face fonts - apache

Question

I need Apache to serve precompressed fonts (not using deflate).
My .htaccess in the /path_to/fonts/ folder look like
RewriteEngine On
RewriteBase /path_to/fonts/
RewriteCond %{HTTP:Accept-Encoding} .*gzip.*
RewriteRule (.*)\.ttf $1.ttf.gz
AddEncoding x-gzip gz
RemoveType application/x-gzip .gz
Response Headers:
Accept-Ranges bytes
Connection Keep-Alive
Content-Encoding **gzip**
Content-Length **31709**
Content-Type **text/plain**
Date Tue, 06 Mar 2012 18:14:51 GMT
Etag "7200000008e241-7bdd-4ba954a7395a8"
Keep-Alive timeout=5, max=99
Last-Modified Tue, 06 Mar 2012 16:11:08 GMT
Server Apache/2.2.11 (Win32) PHP/5.2.9
Vary Accept-Encoding
The Content Length says 31709, that would be the compressed size, but I'm not able to download it.
Could you give a hint?

Answer 1

Here is my solution. It has a bit more polish mostly.
It wont set the type and encoding unless the client supports gzip. Also declares the modules that are used so nothing happens if not all modules are supported.
Folder structure:
fonts/
Shanti-Regular.ttf.gz
Federo-Regular.ttf.gz
Shanti-Regular.ttf
Federo-Regular.ttf
.htaccess
Then .htaccess contains:
# Rewrite URLs to add gzipped version of font when it exits.
<IfModule mod_rewrite.c>
<IfModule mod_mime.c>
RewriteEngine on
#Serve gzip compressed TTF files if they exist and the client accepts gzip.
RewriteCond %{HTTP:Accept-encoding} gzip
RewriteCond %{REQUEST_FILENAME}\.gz -s
RewriteRule ^(.*)\.ttf $1\.ttf\.gz [QSA]
# update the response header of compressed file
# makes browser think mod_gzip did it.
<FilesMatch "\.ttf\.gz$">
AddEncoding gzip .gz
ForceType "application/x-font-ttf"
</FilesMatch>
</IfModule>
</IfModule>
