If, within the Tor Browser, I'm visiting
a.com, and the loaded website does an AJAX query to b.com, will the AJAX query use the circuit established for
a.com, or will the browser establish a new circuit for
b.com and then do the AJAX query using that new circuit?
In case the first question is true, and I disable proxying 127.0.0.1 through Tor, and I visit my local server at 127.0.0.1, and the loaded localhost website does an AJAX query to b.com, will that AJAX query to b.com use my public IP?
NOTE: I'm not sure if by circuit I really mean route.
