title: using http cache in angularjs-rails-resource
body: <p>I'm using the <a href="https://github.com/FineLinePrototyping/angularjs-rails-resource" rel="nofollow">angularjs-rails-resource</a> project to wrap my http rest services.
  One thing I didn't find in documentation is regarding cache, some of my methods should access the server only once and cache their response.</p>
  
  <p>Is there an easy way to achieve this?</p>
