Problem with cached tiles

Hi

I've commented on this in another thread as well, but I decided to make a seperate thread for the topic.

I'm having problems with cached tiles. It seems as the microsoft live maps not always are shown, and ofcourse then a cross-x tile is shown. I've used the activity window in safari and firebug in firefox and noticed that some tiles returns a 404. This does not have to be a problem if it wasnt for the caching of tiles. It seems like it is the browser cache which is the real problem as it won't reload the tile on next refresh. The only solution I've found so far is to empty the browser cache and then refresh...Changing map provider does not help.

I was thinking that maybe if you added a random string to urls of failed requests so that the browser cache won't interfere. It would probably be even better if modestmaps could prevent caching of failed tiles in the first place, but I don't know how we can do that.

Any input on this is highly appreciated.

EDIT: I forgot to mention that I use the lastest as3 build (not from svn trunk). I've changed the flex MapComponent to use the new TweenMap class, which by the way is awesome!
