Document Complete and Fully Loaded

[Honza]

I understand that the 'Document Complete' time is measured when the onLoad event is fired, but how the page-test recognizes that a page is 'Fully Loaded'?

As you pointed out, there can be additional activity and the usual approach today is to wire JS execution to the onLoad event. There can also be cases where the page is actually never finishing loading, (e.g. various chat pages using Comet or pages with video streaming, ok these finish, but after a long time)

What is the actual logic, the page-test uses to decide that the page is fully loaded and the test can finish?
