title: Custom action in RESTful service
body: <p>I've been reading articles about RESTful services for a while, and I understand the importance of using VERBS against RESOURCES.</p>
  
  <p>But there's one thing I fail to understand. What happens if we need to invoke a certain action that is not part of CRUD?</p>
  
  <p>For example, consider I want to make a cat jump. Which format should we use?</p>
  
  <p>Is the following RESTful?</p>
  
  <pre><code>http://host/cats/123/jump
  </code></pre>
