Advantages:
(1) Session provide us the way of maintain user state/data.
(2) It is very easy to implement.
(3) One big advantage of session is that we can store any kind of object in it. :eg, datatabe, dataset.. etc
(4) By using session we don't need to worry about data collesp, because it store every client data separately.
(5) Session is secure and transparent from the user.
Disadvantages:
(1)Performance overhead in case of large volumes of data/user, because session data is stored in server memory.
(2) Overhead involved in serializing and de-serializing session data, because in the case of StateServer and SQLServer session modes, we need to serialize the objects before storing them.
