Sorry to be inexact about this, but the answer is maybe yes and maybe no.
When AJAX JavaScript programs are running in the browser that download various files and informaion asynchronously from the cooperating web server, the files may or not signal an event to the browser.
As far as we can tell, every AJAX application is a little different. Sorry to say.
If you pause eValid during a playback, and you have the Detailed Timings option "ON" then you can look at the Event Log and see the content being delivered from the server into the browser in real time -- in response to whatever you do with the browser face. [Note that the test that you paused to get this effect will likely be ruined, but it easy enough to rerun it later.]
For YOUR AJAX application the thing to do is to go to the particular page in question and then take some actions on the page to see what happens. You will probably be surprized at the volume of the data that is transferred: either astonished that it is so small, or amazed that it so much! Each completed action is shown in separate lines in the Event Log and the byte counts and download times are shown when possible.
That data, which is kept in the EventLog, will tell you how much data is loaded as the result of face-of-the-browser actions you take.
