title: <mvc:resources> - Does it cache to memory? Spring 4.0.5
body: <p>Let the following:</p>
  
  <pre><code>&lt;mvc:resources mapping="/resources/**" location="/resources/" /&gt;
  </code></pre>
  
  <p>And say 2000 requests come to </p>
  
  <pre><code>/resources/script/app/myhax.js
  </code></pre>
  
  <p>If I don't config anything, is <code>myhax.js</code> cached somehow into RAM and the rest of the requests served from there, or are all 2000 requests served from the real path of the file (HDD, usually)? Can Spring be configured to keep this file in RAM after it has been requested for future service directly from memory?</p>
