Setting expire headers for fonts not working

Question

I am using the below code in my .htaccess file to try and set the expire headers for some fonts, but upon checking my firefox cache and the expire header, the font is set to expire in about 12 hours from now; not the 1 year I am trying to set it to.

Here is my code:

# Add correct content-type for fonts
AddType application/vnd.ms-fontobject .eot
AddType application/x-font-ttf .ttf
AddType application/x-font-opentype .otf
AddType application/x-font-woff .woff
AddType image/svg+xml .svg

# Compress compressible fonts
AddOutputFilterByType DEFLATE application/x-font-ttf application/x-font-opentype image/svg+xml

# Add a far future Expires header for fonts
ExpiresByType application/vnd.ms-fontobject "access plus 1 year"
ExpiresByType application/x-font-ttf "access plus 1 year"
ExpiresByType application/x-font-opentype "access plus 1 year"
ExpiresByType application/x-font-woff "access plus 1 year"
ExpiresByType image/svg+xml "access plus 1 year"

What am I doing wrong?

Answer 1

Seems I had to include this bit as well:

ExpiresActive on

With the full code being:

# Add correct content-type for fonts
AddType application/vnd.ms-fontobject .eot
AddType font/ttf .ttf
AddType font/otf .otf
AddType font/woff .woff
AddType font/woff2 .woff2
AddType image/svg+xml .svg

# Compress compressible fonts
AddOutputFilterByType DEFLATE font/ttf font/otf image/svg+xml

ExpiresActive on

# Add a far future Expires header for fonts
ExpiresByType application/vnd.ms-fontobject "access plus 1 year"
ExpiresByType font/ttf "access plus 1 year"
ExpiresByType font/otf "access plus 1 year"
ExpiresByType font/woff "access plus 1 year"
ExpiresByType font/woff2 "access plus 1 year"
ExpiresByType image/svg+xml "access plus 1 year"

Answer 2

I believe your issue is how you define the fonts, and there is no need to add their content-type

 ExpiresByType font/truetype "access plus 1 year"
 ExpiresByType font/opentype "access plus 1 year"
 ExpiresByType application/x-font-woff   "access plus 1 year"
 ExpiresByType image/svg+xml "access plus 1 year"
 ExpiresByType application/vnd.ms-fontobject "access plus 1 year"
