In the HTML5 Application Cache How To I found this:

Double-reload needed — when you access phraffle.com, your browser always checks the manifest file to see if it’s been updated (you will see this happen in the JavaScript console). If the manifest was updated, the browser will download all of the files in the cached file list, BUT, the original content will have already loaded at this point (remember that it’s already cached, so it loads super fast!). This means that you will not see the new content until you hit refresh again. This is a bit of a pain at times! There is a workaround that you can implement using the following JavaScript code:

 if (window.applicationCache) {
     applicationCache.addEventListener('updateready', function() {
         if (confirm('An update is available. Reload now?')) {
             window.location.reload();
         }
     });
 }

This works great with auto appcache, would you merge a PR?
