And regarding media, for an image heavy page, aren't most images cached
by the local browser anyway? As long as the user isn't flushing his
porn.

One of the best things about XMLHttpRequest is that it frees us from
having to transmit fully-formed HTML pages on each request, which is
great for limited bandwidth. The client asks for just the pieces it
needs.

On the other hand, the bulk of a page's content is often not markup or
textual data, but attached media. You don't need (or want)
XMLHttpRequest for that -- you can dynamically add DOM elements (or
tweak existing src attributes) as required for just-in-time media
delivery.
