Answer 1

To make it complete:

• session is not created, unless you call request.getSession(), in your servlet, use request.getSession(false) to get existing session without creating new session
• if you use JSP page, session is automatically created for you - variable session - unless you specify <%@ page session="false" %>
• even if your session is created automatically, you can use session.isNew() to find out, if it has been newly created
