How to add an Access-Control-Allow-Origin header

cors, font-face, header

Solution

So what you do is... In the font files folder put an htaccess file with the following in it.

<FilesMatch "\.(ttf|otf|eot|woff|woff2)$">
  <IfModule mod_headers.c>
    Header set Access-Control-Allow-Origin "*"
  </IfModule>
</FilesMatch>

also in your remote CSS file, the font-face declaration needs the full absolute URL of the font-file (not needed in local CSS files):

e.g.

@font-face {
    font-family: 'LeagueGothicRegular';
    src: url('http://www.example.com/css/fonts/League_Gothic.eot?') format('eot'),
         url('http://www.example.com/css/fonts/League_Gothic.woff') format('woff'),
         url('http://www.example.com/css/fonts/League_Gothic.ttf') format('truetype'),
         url('http://www.example.com/css/fonts/League_Gothic.svg')

}

That will fix the issue. One thing to note is that you can specify exactly which domains should be allowed to access your font. In the above htaccess I have specified that everyone can access my font with `"*"` however you can limit it to:

A single URL:

Header set Access-Control-Allow-Origin http://example.com

Or a comma-delimited list of URLs

`Access-Control-Allow-Origin: http://site1.com,http://site2.com`

(Multiple values are not supported in current implementations)

Problem

I am designing a website (e.g. `mywebsite.example`) and this site loads font-face fonts from another site (say `anothersite.example`). I was having problems with the font face font loading in Firefox and I read on this blog: Firefox (which supports @font-face from v3.5) does not allow cross-domain fonts by default. This means the font must be served up from the same domain (and sub-domain) unless you can add an “Access-Control-Allow-Origin” header to the font. How can I set the Access-Control-Allow-Origin header to the font?
