title: Passing array in GET for a REST call
body: <p>I have a url to fetch appointments for a user like this:</p>
  
  <pre><code>/user/:userId/appointments
  </code></pre>
  
  <p>How should the url look like if I want to get appointments for multiple users?</p>
  
  <p>should it be:</p>
  
  <pre><code>/appointments?users=1d1,1d2..
  </code></pre>
  
  <p>Thanks,
  Chris.</p>
