Assuming you are correct, are URLs traffic data? I exclude any parts 
after the third slash here.

I don't think so - when the DNS is done the URL is content (the URL is 
neither needed nor used to transmit the DNS messages), and when the 
request is sent to the website only the IP address is needed to transmit 
the message (usually).

Caching might complicate this though.
