title: How do I send multiple headers with angularJS resource?
body: <p>Trying to send multiple headers in the same request with angularJS this is what I have...</p>
  
  <pre><code>var auth = $resource("",
          {},
          {
            GetUserDetails: {
              url: Config.api.user.details(),
              method: 'POST',
              isArray: false,
              cache: false,
              headers: ["xx:xx","ff:ff"]
            }
          });
  </code></pre>
  
  <p>But the request just shows...</p>
  
  <pre><code>0:xx:xx
  1:ff:ff
  Accept:application/json, text/plain, */*
  Accept-Encoding:gzip,deflate
  Accept-Language:en-GB,en-US;q=0.8,en;q=0.6
  Cache-Control:no-cache
  </code></pre>
  
  <p>Anyone know the right data structure to send a collection of headers down in the headers property on the resource?</p>
