Cookies are used by web servers to keep track of individual sessions. They are small text files the web server can store on the client and request back, usually containg a unique id and sometimes some other client information. The same effect can be gained by "URL Rewriting" in which the server rewrites all the links on a page it is serving to contain a unique ID.
Does HttpSession internally use cookies ? If yes then why ?
A servlet container (web server) will use one of the above methods to track sessions. This process is abstracted by the HttpSession class.
