Appcache fallback fail is cached

• Component: WebCore Misc.
• Status: RESOLVED WONTFIX

[Mihai]

How to reproduce : 

1. Deploy  a webpage ( index.html)  on https://www.domain.com/ with the manifest file reference.

Config the manifest file as below ( manifest.appcache ): 

CACHE MANIFEST
# Time: Fri Feb 28 2014 11:00:57 GMT+0000 (GMT)

CACHE:
css/style.css

NETWORK:
*

FALLBACK:
/ /offline.html


Set the  webserver to redirect /offline.html to /#/offline.html

Result : You get a correct error :

 Application Cache update failed, because https://www.domain.epek.com/offline.html was redirected.

Next :
 1. Fix the webserver and handle /offline.html appropriately so that it won't redirect anymore.
 2. visit again the webpage 
Result : You still get the error "Application Cache update failed, because https://www.domain.epek.com/offline.html was redirected." which means that if for some reasons the webserver is malfunctioning and doesn't handle /offline.html file accordingly (e.g. issues a redirect) the clients are punished with a PERMANENT cache.

AppCache is now disabled and will be removed in bug 219391.
