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

In short-

request.getSession().getId() - returns a string containing the unique identifier assigned to this session. The identifier is assigned by the servlet container and is implementation dependent.

request.getSession(false) - return session object or null if there's no current session.
