HTTP is a protocol which does not maintain the state of the
client. It is state-less protocol, to make the protocol
stateful we need to provide the session handling mechanism.

This will be provided as per the need of the Application.
The basic categories are 4 ways:1. Using Cookies2. Using
Session API in Servlets3. Using Hidden form fields4. URL
Rewriting.

The best one is using Session objects with help of Session
API. Cookies are harmful because they are allowed to store
on to the client machine. This way you can send a virus
file as cookie So normally the System Admin disables them
to protect their network.

The session API allows us to create SessionID and set for
the client. per Client you can have one session object
which will run in the Server.
