Flash does not see my updated .as files on a server

Hi,

I have a flash app with many .as files. When I change one of them and resave it to the server and then refresh the flash app, it does not see the new .as files.

In IE and FireFox I have deleted my cache and history but the flash app is still reading an old .as file. Is there a way to have flash always look to see if any.as files are new?

thanks
