title: How to set caching policy in RESTkit 0.2
body: <p>I'm unclear how to use the RESTKit 0.2 API to set the caching policy.  I have a request that is being rerun every time I open the app, but I would like it to be cached.  How do I set the caching policy to always cache the request?</p>
  
  <p><strong>Update</strong>
  I learned that RestKit will automatically cache Core Data backed Mappings.</p>
