a Question about sessions

hey guys, me again !!
I have created a session using
HttpSession session = request.getSession(true).
So far, so good, is working smoothly.
1o.) I'm using a servlet and I need to retrieve some values from the session. I'm doing it this way:
HttpSession session = request.getSession(true)
String someString = session.getAttribute("att")
Am I creating a new session if I do this?? or Am I retrieving the current session (what I actually want to achieve)??
2o.) How do I ask if the session is already created?
using isNew()?
or extracting some value from the session and asking if it is null?
thankssss

1) request.getSession(true) retreives the current session if it was already created before otherwise it creates a new one (first time in).
2)There are a number of ways to determine if a session is new. isNew() will work, so will extracting some value from the session and asking if it is null provided you put it into the session before. A third option is checking for request.getSession(false) == null. . .
