306489 - Work Offline does not work on some pages

Status: RESOLVED INVALID

(Firefox :: General, defect)

Description

[Jamax]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.10) Gecko/20050818 Firefox/1.0.6
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.10) Gecko/20050818 Firefox/1.0.6

When in Work Offline mode, it reports the error "This document could not be
displayed while offline.  To go online, uncheck Work Offline from the File menu"

Reproducible: Always

Steps to Reproduce:
1. Go to http://www.inkscape.org/
2. Click on any link to another page
3. Select Work Offline mode from File menu
4. Click Back button 

Actual Results:  
The error dialog saying it couldn't display the page.

Expected Results:  
Display the page

Maybe it has something to do with the time the website was modified, if it is
ahead of the local system time?  In any case, at *least* the back button should
work in offline mode.  For that matter, why is back reloading the page in the
first place?  Maybe it's for shopping carts or something, so they are always
up-to-date?  In any case it's very annoying to be prevented from going back to a
previous page (inkscape was taking like 2+ mins to respond, and 2 minutes to go
back a page is too much!).

www.inkscape.com sends http headers explicitly telling firefox not to cache the
page, so firefox does not cache the page and so it cannot be available offline.
