Overview
HTTP is a stateless protocol and maintaining a conversational state of the server is not directly supported by the protocol. HTTP provides no build-in way for a server to recognize that a sequence of requests originate from the same user. Since CGI, developers have been using various techinques to track the session: user authentication, hidden form fields, URL rewriting and persistent cookies. The servlet API brings improved support for session tracking. The support is built in top of the traditional techniques and it simplifies the task of session tracking in your servlets.
