Recorded 23 May 2011 at the Roots conference in Bergen, Norway.

Abstract:

HTML5 provides a new caching feature for browsing webapps when offline. Correct caching can provide a more responsive user experience, and reduce load on the server. This makes for great opportunities for web developers, but can also result in boatloads of frustration and hours spent debugging something not meant to be debugged. In this talk I will give a quick tour of caching webapps through the HTML5 cache manifest, and give some practical advice on how to avoid the frustrating parts.
