title: Chrome - why is it sending if-modified-since requests?
body: <p>I have a page with lots of small images (icons). When used with chrome, each time the page is reloaded, chrome requests each icon from the server with if-modified-since header.</p>
  
  <p>All icons are served with expires and max-age headers. Firefox loads images from its cache.</p>
  
  <p>Why is chrome doing that and how can I prevent it?</p>
  
  <p>Thanks</p>
