ExpiresByType image/gif "access plus 120 minutes"
ExpiresByType image/jpeg "access plus 120 minutes"
ExpiresByType image/png "access plus 120 minutes"
ExpiresByType text/css "access plus 60 minutes"
ExpiresByType text/javascript "access plus 60 minutes"
ExpiresByType application/x-javascript "access plus 60 minutes"
ExpiresByType text/xml "access plus 60 minutes"
ExpiresByType application/javascript "access plus 60 minutes"
ExpiresByType application/x-font-ttf "access plus 30 days"
ExpiresByType application/x-font-woff "access plus 30 days"
ExpiresByType application/x-font-eot "access plus 30 days" …
