title: How to CORS Allow Headers in Sails
body: <p>I want my server to allow 'Authorization' header for my mobile app. Currently my webserver is in sails and I use sails. My routes code is</p>
  
  <pre><code>'post /auth/local' : {
      cors: {
         origin: '*'    
      },
      controller: 'AuthController',
      action: 'callback'
  },
  </code></pre>
  
  <p>When my client sends a request with 'Authorization' in header I get error</p>
  
  <pre><code>XMLHttpRequest cannot load http://localhost:1337/auth/local. 
  Request header field Authorization is not allowed by Access-Control-Allow-Headers.
  </code></pre>
  
  <p>How do I specify in my routes code that 'Authorization' header is also allowed?</p>
