Hi! Yeah I know about this method too. The reason I decided not to
mention it... or even use it in my projects yet... is simply because it
is fairly immature still... and more complicated than the iframe way.
Iframe's have been supported for quite a while now... so their
functionality is quite predictable in most cases. I designed an RPC web
app that had the ability to retreive practically any data required
without reloading the page... including submitting a form via POST
without any problems... I have only tested it under IE and Gecko baseb
browsers though...
