| min | video details |
|---|---|
| 00:05 | accessing an html page linked to a manifest file |
| 00:07 | allowing files local storage for Offline use |
| 00:12 | accessing the about:cache file and deleting the regular cache |
| 00:23 | checking the cached resources (3): the html page, its style page "main.css" and the manifest file itself |
| 00:54 | updating 2 files: the html one and the css file |
| 01:50 | the updated files have been uploaded on server, replacing the existing ones |
| 02:09 | disadvantage: the updated resources do not display; while accessing the same page as before, we still see the old version |
| 02:29 | test from another browser: Google Chrome; the updated web page displays |
| 02:29 | the updated version of the web site displays if users: clear their OfflineCache files and re-access the web page, or if they change their Browsers and re-access the web page.. but waiting and hoping for this to happen is NOT a solution |
