Hello falguni..
Well, JSP makes available certain implicit object(like request,
response, session, application, pagecontext etc..) for your use directly in
the jsp pages. Now, if you say session=false in the page directive, then
the implicit object session is not created when the jsp is transformed to a
servlet and the same is available if its set to true, by default its always
true.
Not you might have a question as to why this option is only given for
the session object and not for other object. Well to my knowledge web
server to support additional users/traffic has tendency to persist the
session object. Now when a session is read it might be performance
drawback, i think this option is available to avoid this bottleneck. So
unless u need it dont have it.
Also the code what u have written will result in a jsp error as a
variable with name session would have already been declared if u havent
said false in the page directive. If u give a different name it will work
but not considered a good practice as it already available to u..
people pls correct me if i am wrong anywhere.....

In Jsp the page directive takes an attribute session. What I understood
of this attribute is that if the attribute is set to false, an instance
of HttpSession is not created and if it is set to true the instance
gets created.
My question is why is this attribute required because in the jsp page I
willl be writing
<%
HttpSession session=request.getSession(true);
session.setAttribue(" ___","___");
%>
If I am writing the above code what is the use of the session attribute
in the page directive.
Please help me!!!
