Cookie Class in Servlet

A cookie is stored on a client and contains the state information. The Cookie class encapsulates a cookie. Cookies are valuable for tracking user activities. A cookie can save the user’s name, address, and other information. The user does not need to enter this data each time he or she visits the store. Some of the information that is saved for each cookie is given below:

1. Name of the cookie
2. Value of the cookie
3. Expiration date of the cookie
4. Domain and path of the cookie

Name and Values of the cookies are stored on the user’s machine.

Expiration date determines when this cookie is deleted from the user’s machine. If an expiration date is not explicitly assigned to a cookie, it is deleted when the current browser
session ends. Otherwise, the cookie is saved in a file on the user’s machine.

Domain and path of the cookie determine when it is included in the header of an HTTP request. If the user enters a URL whose domain and path match these values, the cookie
is then supplied to the Web server. Otherwise, it is not.
