Hi,

I'm still experiencing problems with IE8 because of the cached images.
The problems is that unfortunately the servers encourage browsers and
proxy caches to keep a cache copy for a very long time ("public, max-
age=22222222", i.e. 257 days) and not all users know about Ctrl+F5
(which only works for the initial tiles, once you move or zoom the map
those request run in normal mode instead of continuous no-cache like
Firefox 3.5).

To accelerate the process, could you change the API to make a slight
variation of the URLs? Swapping arguments positions would be enough,
for instance browsing 
http://mt1.google.com/vt/v=app.113&hl=es&src=api&x=5&y=10&z=4&s=G
shows me no image but 
http://mt1.google.com/vt/v=app.113&hl=es&src=api&x=5&y=10&s=G&z=4
does (the transparent proxies of my ISP also consider the second URL
as a completely different one).

Thanks,
Hernán

PS: The tests were conducted with Marcelo's main map and it is fully
working in Firefox 3.5 now after using Ctrl+F5 and traveling many
tiles to purify both my local cache and my ISP's proxy caches.
