title: How to add version number to HTML file (not only to css and js files)
body: <p>Many people use version numbers on css and js files to force non-cached versions to load up on webpages when updates are published:</p>
  
  <p>CSS example:</p>
  
  <pre><code>&lt;link rel="stylesheet" type="text/css" href="style.css?v=2017-03-17"&gt;
  </code></pre>
  
  <p>JS example:</p>
  
  <pre><code>&lt;script type="text/javascript" src="js/myscript.js?v=2017-03-17"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>I've noticed that by adding version numbers to css/js files, the web browsers will also load up the <strong>HTML file</strong> (from which the css/js files are referenced from) from scratch and not use the cached version.</p>
  
  <p>Is this a sufficient way of ensuring that HTML-files are displayed from scratch in all web browsers, or is there a way to set a version number to the <strong>HTML file</strong> as well, to ensure newly updated HTML-documents are not loaded from a browser's cache?</p>
