Difference between request.getSession().getId() and request.getSession(false)?

Question

What do these calls actually mean in terms of session?

System.out.println(\"print1: \"+request.getSession().getId());
System.out.println(\"print2: \"+request.get         


        

Answer 1

request.getSession().getId();

Will return unique string id assigned to already started session. Generation of id is vendor specific like apache, jboss etc.

request.getSession(false);

It will return session object associated to particular request if session object is associated it will be returned or it will return null if its is not started by server.
