HI,
I would like to know where it is stipuled that
In order to share the same shopping cart object between requests, the same session object that is associated with a user would be required. However, when requests are made by the same user to different web applications, the same session object cannot be retrieved using the getSession() and getSession(boolean create) methods declared by the interface javax.servlet.http.HttpServletRequest.
extracted from a mock exam.
So, the session may only be retrieved from the same web application?
I would be very grateful for any precision about this topic,
Regards,
Cyril.

This is from the J2EE spec (available on the java.sun.com site.) It states that web applications cannot share sessions. However, servlets within a web application can share a session.

Read the Servlet 2.2 specification, page 36, section 7.3 on "Session Scope", or the Servlet 2.3 specification, page 51, section SVR7.3, or the Servlet 2.4 specification, page 56, section SVR7.3.
They all say the same thing.
