308296 - Images cached improperly

Status: RESOLVED DUPLICATE of bug 89419

(Core :: Networking: Cache, defect)

Description

[info665-s1]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.10) Gecko/20050716 Firefox/1.0.6 (ax)

In the fourth post here
http://forums.mozillazine.org/viewtopic.php?p=1661980#1661980
there is a square image that should be different/random each time.

Reproducible: Sometimes

Steps to Reproduce:
1. Open http://forums.mozillazine.org/viewtopic.php?p=1661980#1661980 in a new tab.
2. Open another tab with the same URL.


Actual Results:  
The images in the two tabs are identical.

Expected Results:  
The images should be different in the two tabs. If they aren't, that's because
they are impropely cached.

1. After redirection, the Cache-control headers in the new response (location 2)
are not considered and the response is still cached improperly according to the
lack of Cache-control headers in the first response.

2. The URL in the Location header is not considered as another URL but as part
of the first response that should be cached. This way when the location in the
Location header is changed, the browser uses the old URL that is cached instead
of making new redirection to the new location.

Both refer to improper caching.
There is no such problem with Internet Explorer.

Yhe first image on the post doesn't reload (not sure if it was sopposed to),
however, the second one did the 4/5 times, got to a gorrila and then stopped for
1 refresh, then went to an airplane.

Do not reload the page but only surf/click links or open in new tabs (as many 
as you want - it always shows the same image). If you refresh the page, the 
image is refreshed too.

This is a know problem with image caching and HTTP redirects.
