XMLHttpRequest in widgets

I am currently pulling two remote .js files containing document.writes only that render HTML via SCRIPT tags in the main body of my widget.  I need to refresh these two files based on a timer and find that doing a window.location.reload() breaks the flip animation.  So it seemed to me that XMLHttpRequest would be a good way to go, as it can pull raw text strings in addition to individual pieces of an XML feed.  The thing is, there is a restriction, stated in Apple's docs:

( http://developer.apple.com/internet/webcontent/xmlhttpreq.html )

" Second, the domain of the URL request destination must be the same as the one that serves up the page containing the script. This means, unfortunately, that client-side scripts cannot fetch web service data from other sources, and blend that data into a page. Everything must come from the same domain. Under these circumstances, you don't have to worry about security alerts frightening your users. "

...yet, I see it used in several widgets out there today including Xia's RSS Bean widget.  Surely this constitutes pulling data from a remote domain.  How is it working?  I ask because I am having trouble getting my implementation to work, as testing in Safari and Firefox in the early development of this part of my widget.

Thanks.
