Thnx for the reply people, one thing that Andreas pointed out to me from the spec :
"Indicates that the page requires participation in an (HTTP)session. If true then the implicit script language variable named session of type javax.servlet.http.HttpSession references the current/new session for the page. If false then the page does not participate in a session; the session implicit variable is unavailable, and any reference to it within the body of the JSP page is illegal and shall result in a fatal translation error. efault is true."
it says that the session is unavailabe, now is it for that page and that page cannot participate in the session or the session is not created at all for that page and hence saving the session object instantiation.

In terms of Jasper, Tomcat's JSP engine, it appears that a HttpSession is set to null if session="false" therefore no instance is made.
In terms of the JSP Spec, session="true" by default.
In terms of whether it is best practice to set session="false" when yuo know you don't need a session I have no idea. I suppose it makes sense if it saves an instantiation of HttpSession, I've never done it.
Perhaps a Jasper dev/others can comment.
