Cookies only loaded after refreshing page

Question

I'm truly sorry, this is the second or third question about cookies, but honestly I can't understand why this happens...

On the login page I set the cookie this way:

Cookie cookie = new Cookie("username", user);
cookie.setMaxAge(365 * 24 * 60 * 60);
response.addCookie(cookie);

And then user is redirected to a different page.

I deleted almost all my code (to make sure there are no conflicts), except this:

<%@page import="javax.servlet.http.Cookie"%>

<html>

<%
	Cookie cookies[] = request.getCookies();
	Cookie nome = null;
	Cookie aux_login = null;
	int auxiliar = 0;
	Cookie idaux = null;
	String jog1="",jog2="";

	if (cookies != null) {
		for (int i = 0; i < cookies.length; i++) {
			out.println("<br>"+cookies[i].getName()+" <br>");
			if (cookies[i].getName().equals("username")) {
				nome = cookies[i];
			}
			if (cookies[i].getName().equals("aux_login")) {
				aux_login = cookies[i];
			}

			if (cookies[i].getName().equals("idsala")) {
				idaux = cookies[i];
			}

		}
	}
	out.println("ARE NULL ??");

	if (nome == null) {
		out.println("Cookie 'username' nao encontrada");
        else
         welcome nome.getValue()...



	}

So at the first load cookies are not found (that nome == null is verified), but if I refresh the page they are found - so they exist, but in a first load they are not being detected...

What am I doing wrong? Thinking about the matter this would be normal (the information displayed of course) if the page was the same, but it's a different page...

You should add the domain for that cookie using path. By default a cookie is only valid for that page only (in this case the login page). For more info (and have a look at path, you should add ;path=/):

For JSP have a look at setDomain:

Good luck!

I think i know what's happening, my login page is index.jsp and my "second page" is default.jsp (yes I know this is bad practice, but I'm just learning JSP for a few days, give me time :) ). So, I tried to do:

SQL

if (nome == null) {
    out.println("Cookie 'username' nao encontrada");
    and with js script..
    window.location.reload();

I was redirectedto index.jsp. Thats when I noticed when I do a sucessfull login (and go to default.jsp) my URL is still (for some motive!!) index.jsp.
Looks like its because doing the redirect this way:

XML

<jsp:forward page="/default.jsp" />
<%

Problem solved with response.sendRedirect("default.jsp");

Be advised that request.getParameter("t1") from previous page will not work anymore.

P.S: It's always safer use sessions for authentication.
