Cookie

Synopsis

The Cookie class provides servlets with an easy way to read, create, and manipulate HTTP-style cookies. Cookies provide a way to store a small amount of information on the client and are typically used for session tracking or storing user-configuration information. The getCookies() method of HttpServletRequest returns an array of Cookie objects. To set a new cookie on the client, a servlet creates a new Cookie object and uses the addCookie() method of HttpServletResponse. This must be done before sending any other content, since cookies are created within the HTTP header stream. The various methods of the Cookie class allow a servlet to set and get various attributes of a Cookie object, such as its path and domain.
