sorry if this post is not specific to ext (moderator please delete at will) but i'm running into something that i'm hoping one of you scripters has seen before. i have put in place a simple version system for my volitile files (js and css) so that i can take advantage of client-side browser caching. i want the browser to cache css and js files for the lifetime of a deployment .

i started to look at the caching behavior in firefox to ensure that files were being fetched from the cache between deployments. what i'm seeing, or what firebug is showing me, is that files are fetched from the cache only from top level while embedded iframes seem to always go to the server for these resources.

has anyone else observed this behavior? i don't read a lot of forums, aside from this one, related to js so please forgive me if this isn't the right place to post this.
