106635 - No recognition of image already having been loaded

Status: RESOLVED DUPLICATE of bug 79020

(Core :: Networking: Cache, defect)

Description

[Hogarth]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.5+) Gecko/20011022
BuildID:    2001102210

Mozilla reloads over and over the same image when it is used multiple times on a
page instead of loading it once, recognising that further requests are for the
same image (via the URL of that image) and reusing the image that was already
loaded as many times as necessary.

Reproducible: Always
Steps to Reproduce:
1.Flood your link (so that you can watch)
2.Go to the above page, load it at least once
3.Hit shift-reload
4.Watch as the many stars are drawn slowly and painfully, one by one.

(You can skip 3 I guess but I'm just laying out the steps as I did them... and
you can probably skip flooing your link. I was downloading mozilla over my 56k
modem at the time and so the effect was most pronounced.)

Actual Results:  The green stars, marking a final mark for a DVD, are drawn very
slowly as if each one were loaded over and over again. When looking at the image
list in the page info window you can see many entries for the same image.

Expected Results:  Each image gets loaded once regardless of the number of times
it gets used on the page. When an image IS reused, mozilla should reuse the
already loaded version instead of going off for another round.

Memory cache at 4meg
Disk cache at 50meg
'Compare the page in the cache to the page on the network' was set to
'automatically'

The little mozilla theme was used.

The system is linux 2.4.12-ac5 with Debian Woody.
