How do I send cookies from a servlet?
HTTP is a stateless protocol, which makes tracking user actions difficult. One solution is to use a cookie, which is a small piece of data sent by a web browser every time it requests a page from a particular site. Servlets, and CGI scripts, can send cookies when a HTTP request is made – though as always, there is no guarantee the browser will accept it. Cookies are represented by the javax.servlet.http.Cookie class. Cookie has a single constructor, which takes two strings (a key and a value).
