title: Phusion Passenger + Heroku + Cloudfront: CORS Configuration
body: <p>I have fonts served from cdn.myapp.com using Cloudfront.</p>
  
  <p>I was using the <a href="https://github.com/ericallam/font_assets" rel="nofollow">font_assets</a> gem which helped me sending CORS headers to have my fonts accepted in Firefox (among others).</p>
  
  <p>I recently moved my webserver to Phusion Passenger, I'm very happy with this (speed!).</p>
  
  <p>But since my migration, I can't send these headers and I suspect nginx to be responsible for it. </p>
  
  <p>How can I send custom headers with Phusion on Heroku? Can I access nginx config from heroku, or is there another config to set?</p>
  
  <p>Thanks for support!</p>
