Session Tracking in Servlets | Servlets Tutorial For Beginner | Advance Java Tutorial In Hindi -86 смотреть онлайн

Session simply means a particular interval of time.

Session Tracking is a way to maintain state (data) of an user. It is also known as session management in servlet.

Http protocol is a stateless so we need to maintain state using session tracking techniques. Each time user requests to the server, server treats the request as the new request. So we need to maintain the state of an user to recognize to particular user

Session Tracking Techniques

Cookies
Hidden Form Field
URL Rewriting
HttpSession

Cookies in Servlet
A cookie is a small piece of information that is persisted between the multiple client requests.

A cookie has a name, a single value, and optional attributes such as a comment, path and domain qualifiers, a maximum age, and a version number.
