775398 - Offline application cache is not updating, despite manifest update and refresh

Status: RESOLVED WONTFIX

(Core :: Networking: Cache, defect)

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:13.0) Gecko/20100101 Firefox/13.0.1
Build ID: 20120614114901

Steps to reproduce:

We have an offline web application (just a collection of links to applications in various dev environments). The cache.manifest (cache.manifest.jsp in this case) file list almost never changes, but the links get updated quite often as applications are added or removed. Whenever this happens, the cache.manifest has a comment field on the second line with a date that gets updated.


Actual results:

The change is detected by the application, and the update event fires properly, however refreshing the page does not display the updated content. This has been reproducible by multiple team members who access the page. The only way to update the content has been to remove the offline data from tools-options-advanced-network and then refresh. Also, sometimes when the page is refreshed multiple times in 'offline' mode, it will stop loading all together, but that is not related to this I think.


Expected results:

The application detects the cache manifest change, and updates the cache with the latest version of the content listed in the cache manifest. It may not matter, but we pretty much all have firebug installed with 'disable browser cache' selected.
