That's not always a problem - that means you can use the back/forward
commands of the browser to move backwards/forwards through the dynamic
functionality of the site. Google uses that so you can go back/forward on,
say, google maps, and you don't leave the page, but you traverse your
browsing history within the actual map. If that makes any sense :)

Iframe and the XML requests are for completely different things. Getting
large amounts of data on a user signal? Use Iframe. Getting/setting some
variables on the fly? XML request. They're both suited to different tasks,
they just both happen to be good at getting data from a remote server.

Which offers you nothing using the <iframe> method doesn't ;)
