title: HTML 5 Application Cache catch events in Chrome
body: <p>I've created a website using HTML 5 offline Application Cache and it works well in most cases, but for some users it fails. In Chrome, when the application is being cached, the progress is displayed for each file and also error messages if something goes wrong, like:</p>
  
  <p>Application Cache Checking event</p>
  
  <p>Application Cache Downloading event</p>
  
  <p>...</p>
  
  <p>Application Cache Progress event (7 of 521) <a href="http://localhost/HTML5App/js/main.js" rel="nofollow">http://localhost/HTML5App/js/main.js</a>
  ...</p>
  
  <p>Application Cache Error event: Failed to commit new cache to storage, would exceed quota.</p>
  
  <p>I've added event listeners to window.applicationCache (error, noupdate, obsolete, etc.), but there is no information stored on the nature of the error.</p>
  
  <p>Is there a way to access this information from the web site using JavaScript ?
  I would like to determine somehow which file caused the error or what kind of error occurred.</p>
