@page session
Why set <@page session = "false">?
One reason would be performance and memory.
If you have a page that doesn't need to be involved in a session
(like say, an about.jsp or faq.jsp)
then the default behaviour of involving every JSP in a session will
impose the overhead of creating a new session object
(if one doesn't already exist) and increased memory usage as more
objects reside on the heap.
