Just wanted to clear one point up...

The web is *not* a "push" model; it's a "pull" model.

The HTML document is nothing but a text document
which has references to other elements that are
available to the browser, should it choose to
request them; but it is incumbent upon the
browser to request each and every one of
those other elements from the server before
they are transferred.  The server will not send
something that was not first requested by the
browser.

It's misunderstandings like this that make content
providers twitch every time an eyeball network
says "well you're *sending* all this data at my
network" -- absolutely nothing is being sent
that was not explicitly requested by the browser
first.   ^_^;

Thanks!
