AJAX and Lightbox?

Is there a way to see the details of a user’s AJAX requests, in the way
that you can use ‘request’ to see the user’s browser, or the referrer?

And secondarily, if I am fulfilling image requests through Lightbox
(2.0) – is there a way to log those requests? I was hoping there was
something like XHR? that would instead give me the details of the
request.

Thank you for your help.
