How do I set a cookie within a JSP page?

Setting cookies from within a JSP page is similar to the way they are done within servlets. For example, the following scriptlet sets a cookie "mycookie" at the client:

<%
       Cookie mycookie = new Cookie("aName","aValue");
       response.addCookie(mycookie);
 %>

Typically, cookies are set at the beginning of a JSP page, as they are sent out as part of the HTTP headers.
