Cross domain caching

Does anyone know how the browser caches .swf and it’s content?
For example, if i have an image slideshow that load data specified in XML on the domain www.thisDomain.com, will it be cached for access if the same swf is used on the domain [URL=“http://www.anotherDomain.com”]www.anotherDomain.com or does it have to be re-cached?

any help would be much appreciated!
