>No (except TCP keepalives and a FIN when your browser finally decides to close the connection). These could reveal to future eavesdroppers what sites you visited in the past. >Huh? Each TCP socket only connects your computer to a single host, and will only be reused if your browser needs to send more traffic to that same host. Your computer isn’t going to randomly send packets to the wrong website, whether or not you have an open connection to that website. I'm talking about an attacker that is passively sniffing your traffic. For example someone on the same wifi network as you who is listening to your traffic. Not some random website.
