Cookie lost in RequestDispatcher

[wolfmah]

I am trying to set cookies in a controller servlet before dispatching to a JSP file, but the cookies are not set in the JSP file.

Servlet

Cookie cookie= new Cookie("userName", "wolfmah"
cookie.setMaxAge(60*60*24*7*1);
cookie.setDomain("wolfmahheaven.net"
response.addCookie(cookie);

RequestDispatcher rd= getServletContext().getRequestDispatcher("/cookie1.jsp"
rd.forward(request, response);

JSP (cookie1.jsp)

Cookie[] cookies= request.getCookies();

if (cookies != null) {
for (int i= 0; i < cookies.length; ++i) {
Cookie currentCookie= cookies;

if (currentCookie.getName().equalsIgnoreCase(&quot;userName&quot)
out.println(currentCookie.getValue());
else
out.println(&quot;null&quot;
}
}


The only output that I get is &quot;null&quot; two times because Tomcat seem to create 2 cookies itself, but mine isn't there.

request.getCookies() returns cookie set by the client browser. It will not contains any cookie that you just added to the response object within the same request session.

In other word, cookie won't appear until a round trip back from the client.
