title: HTML - How can I check if a file (.js or .css) was loaded or picked up from the cache?
body: <p>First, I needed a way to force browser always load .css and .js files. I solved it by putting a sufix in the files:</p>
  
  <p>Before:</p>
  
  <pre><code>&lt;script type="text/javascript" src="file.js"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>After:</p>
  
  <pre><code>&lt;script type="text/javascript" src="file.js?v=1"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>That aparently worked. </p>
  
  <p>Now, I need to know if that really worked. Sure, I can edit the file and check the changes in my browser but I need a way more specific, something like an option in the browser that show "File loaded from the cache" / "New file loaded from the folder".</p>
  
  <p>Can you help me?</p>
