Thanks, Rob pal!

In my limited experience, a TCP process will listen on a specific port,
maybe 80, and then when a request comes, it will create another port for a
TCP connection.

My question is what is the port squid is using to listen. Simon told me
squid is using port 80 to do the listen task and use a random port(>1023)
to server for each TCP connection. Do you agree with him?

Best regards,
George Ma
