title: How to add response header in VHost or Passeneger (Ruby)
body: <p>I have problem with Same Origin Policy. I want to make cross domain request - I found nice solution: <a href="http://www.w3.org/TR/cors/" rel="nofollow">http://www.w3.org/TR/cors/</a></p>
  
  <p>But I don't want set header in Apache because I have there many domains and only one need it. Is it possible to add <strong>Access-Control-Allow-Origin</strong> header via Virtual Host or Passenger? </p>
  
  <p>I do it, because I need use Redmine REST API (XHR) in Chrome/Mozilla plugin.</p>
