How to Clear HTML 5 Offline Application Cached Manifest

HTML 5 Offline Application can be difficult to troubleshoot because you tend to see app cached manifest data, not the latest.

There are at least 2 ways to help:

  1. Use Chrome’s Incognito mode so it always loads things from scratch.
  2. chrome://appcache-internals/ and Remove the appcache

Of course, the easy way is just comment out the html tag manifest during development.  Enable manifest only when you want to test the offline scenario.
