Not quite. In the classic form, it creates an XMLHttpRequest object
and makes a request to the server, which returns XML. XML doesn't need
to be passed, and PHP doesn't need to be used to generate the response.

These days (i.e. the non-classic form), its generally accepted that
Ajax means any use of JavaScript to make an HTTP request and update
the page based on the response.

The XMLHttpRequest object should have been destroyed when the browser
discarded the page. The response from the server should be ignored.

I can't reproduce the problem. The only complaints my debugger gives
are warnings that you are using document.all.
