Closes the browser completely causing the browser executable to actually
exit or just closes the current window ?

At this point run netstat and see what state the connection is in.

This behaviour is potentially browser specific; I could see how a
browser may potentially cache connections in case you decide to
go back to the page you just left.

After you browse to a different URL, check netstat and see if the
original connection is still in an ESTABLISHED state or if the
browser has actually closed the connection.
