334850 - error page should reload itself if it was loaded from a page meta-Refreshing itself

Status: NEW

(Core :: Networking, defect, P5)

[David Baron :dbaron: (⌚️UTC-5, no longer working on Mozilla)]

When I have a page like http://tinderbox.mozilla.org/showbuilds.cgi?tree=Firefox (which has a meta-refresh to reload itself) loaded and I suspend my laptop, when I resume, the page tries to meta-refresh itself before the laptop is conected to the network and is replaced by an error page saying the page could not be found.  I sometimes find these pages still around hours after I've resumed.

It would be nice if an error page that was the result of a page refreshing itself had the same refresh as the page so that it would retry again at the same interval (after the network is up).

Steps to reproduce:
 1. load a page that meta-refreshes itself
 2. suspend computer (in a way that causes network to stop, and then restart when resuming)
 3. resume computer

Actual results:  Page permanently replaced by an error page that never refreshes.

Expected results: Page continues to refresh, possible interrupted by a transient error page.

(It's possible that this situation would also be improved by changes to make Mozilla understand offline status from NetworkManager.)
