How do I read browser cookies from a servlet?
Reading cookies from a servlet is quite easy. You can gain access to any cookies sent by the browser from the javax.servlet.http.HttpServletRequest passed to the servlet’s doGet, doPost, etc methods. HttpServletResponse offers a method, Cookies[] getCookies() which returns an array of Cookie objects. However, if no cookies are available, this value may be null, so be sure to check before accessing any array elements.
