title: Using Google Maps V3 offline, e.g. with cache-manifest?
body: <p>I'm writing an HTML5 mobile application that uses Google Maps V3 with a custom layer of OpenStreetMap tiles. </p>
  
  <p>The OSM tiles (from <code>tile.openstreetmap.org</code>) are set to cache for just over 24 hours, and I'm using a cache-manifest for all my HTML/JS/CSS. </p>
  
  <p>So the application could in theory be used offline, except the Google Maps interface isn't happy when offline. </p>
  
  <p>It always wants to call to the Google Maps server at <code>http://maps.google.com/maps/api/js?sensor=false&amp;region=GB</code> - when this fails, Google Maps fails to load. </p>
  
  <p>Is there any way to use Google Maps V3 API offline?</p>
  
  <p>Could I cache-manifest <code>http://maps.google.com/maps/api/js?sensor=false&amp;region=GB</code>, or would that be a bad move?</p>
  
  <p>(Sorry for this rather beginner question, let me know if I can explain better!)</p>
