Bug#635466: regression: cache used to load images after clicking refresh

[Jason Woofenden]

Package: chromium
Version: 12.0.742.112~r90304-1
Severity: minor

This is a regression, it worked not too many months ago.

The trouble is that the refresh button no longer re-fetches map
tiles on openstreetmap.org.

To reproduce:

1.	Go to: http://openstreetmap.org/ zoom in somewhere

2.	click "permalink"

3.	right-click -> inspect element and go to the Network tab.

4.	click refresh

5.	in the inspector window, look for tile images. they have names
	like 24089.png

What I expect: I expect these to be downloaded from the server.

What happens instead: they are pulled from the chromium cache.


This is particularly annoying when I've edited the map recently,
and would like to check over my work. It seems to not be possible
to get the new versions of the map tiles to show on the map. It
even shows old map tiles sometimes after telling chromium to clear
my cache.

And even worse... if I right-click a map tile that I know should be
updated, and click "open image in new tab", then refresh that new
tab, I see the new version of the image. and _after_ seeing the new
version of that image in the other tab, hitting refresh on the map
page still shows the old image.


Thanks,    - Jason
