Actually, one session corresponds to a set of requests from the same client within a
certain period of time (the connection between the client and server may be
closed and reopened, but the session remains).
But yes, a user with multiple browser windows can cause multiple requests
within the same session. Other cases are when you use frames where the
content of each frame is from a JSP page; the browser will request all frames
at roughly the same time so you have multiple requests in the same session.
And another is a user that keeps hitting the Submit button before the response
is delivered; every time a new request is made but the previous request may
still be executing.
