title: Cache busting specific modules with RequireJS
body: <p>This question has been asked several times but not specific to this example.</p>
  
  <p>Here is an overview of our application:</p>
  
  <ul>
  <li>Simple server routing with Express on Node</li>
  <li>Single page backbone application</li>
  <li>Core modules and libraries (JS/CSS) that don't change</li>
  <li>Widget JS/LESS/HTML files that frequently change</li>
  </ul>
  
  <p>During development, I am looking to cache bust files that change but not those core libraries to speed up my page reloads and quicken my development.</p>
  
  <p>I have found explanations on:</p>
