title: HTML5 cache downloads root every time
body: <p>I am playing with HTML5 app cache and right from the beginning I ran into issues:/
  I am trying to have simple offline fallback for my page so that there would be nice styled page instead of classic offline error. According to few resources I have red I created this manifest file.</p>
  
  <pre><code>CACHE MANIFEST
  # 0.01
  CACHE:
  
  NETWORK:
  *
  
  FALLBACK:
  / /offline.html
  </code></pre>
  
  <p>The problem is, that the browser loads into the cache not only the <code>offline.html</code> file, but also the root page, which leads into that page is displayed with lot of errors (no js loaded, no imaged loaded, no CSS, ...) while offline and <code>offline.html</code> is completely bypassed by the browser.
  The screenshot below shows logged information about caching progress. You can see there, that the browser downloads both files, instead of only the <code>offline.html</code> as I am trying to do.</p>
  
  <p>All this has been done in latest dev Chrome (23.0.1262.0 dev)</p>
