For example, if the main page is served from macromedia.com, the wrapper page could be served from external.macromedia.com, and this would prevent any Macromedia Flash movies inside the wrapper page from accessing data associated with macromedia.com.

i think:
"Macromedia Flash movies inside the wrapper page" got document.domain equal to "external.macromedia.com", then they can invoke "getURL" to set document.domain equal to "macromedia.com", and start "accessing data associated with macromedia.com".

i was putting a flash tour on editive.com, and would like flash content hosted on 209.203.227.117 to read editive.com cookie(where the language settings are stored). during googling, i came across this mistake in mpsb02-08.
