title: Reload page without cache revalidation
body: <p>My server sends page with many components to the client.
  All my pictures, js and css are cached.</p>
  
  <p>In my page, there is a javascript like this :</p>
  
  <pre><code>function refresh(){
      window.location.reload();
  }
  var timer = setInterval("refresh()", 60000);
  </code></pre>
  
  <p>In fact, I need to reload my page frequently to verify if there is new informations on my server.</p>
  
  <p>But, the problem is : <strong>when I reload my page, all my components (pictures, css, js...) are revalidated</strong>. I would like to check only my information but not all components.</p>
  
  <p>So, <strong>I would like to know if it's possible to revalidate only a part of my page, without pictures, js and css revalidation</strong></p>
  
  <p>Thanks</p>
