title: Cache busting via params
body: <p>We want to cache bust on production deploys, but not waste a bunch of time off the bat figuring out a system for doing so.  My thought was to apply a param to the end of css and js files with the current version number:</p>
  
  <pre><code>&lt;link rel="stylesheet" href="base_url.com/file.css?v=1.123"/&gt;
  </code></pre>
  
  <p>Two questions:  Will this effectively break the cache?  Will the param cause the browser to then never cache the response from that url since the param indicates that this is dynamic content?</p>
