title: Force download from local cache in Google Chrome
body: <p>How can I force Google Chrome to download some .js/.css/images from local cache if remote file is not available (like if Chrome is configured to use Squid proxy, which will serve this file for me, even if cdn is not available).</p>
  
  <p>For example, I load <a href="http://example.com" rel="nofollow">http://example.com</a> which uses jquery library, located in CDN with address <a href="http://cdn-example.com/js/jquery.latest.js" rel="nofollow">http://cdn-example.com/js/jquery.latest.js</a></p>
  
  <p>Suddenly cdn-example.com becomes unavailable/respondes very slowly/respondes with 404 error/etc.</p>
  
  <p><a href="http://example.com" rel="nofollow">http://example.com</a> is still available but is unusable because jquery is not loaded. </p>
