<%
//creating a cookie
Cookie mycookie = new Cookie("aName","aValue");
response.addCookie(mycookie);
//delete a cookie
Cookie killMyCookie = new Cookie("mycookie", null);
killMyCookie.setMaxAge(0);
killMyCookie.setPath("/");
response.addCookie(killMyCookie);
%>
?
In First line, We are creating cookie object of cookie class,
after that we are sending response to server.
we make object which take null value and it, setting life 0, after that we cookie send token to server, with null value, and max age 0.
then cookie have no life.
