Can't add cookies on Localhost

Question

Hi,
I am trying to save cookie and then read it in the same JSP page. But I can't read it, not sure if its been added. Here is the script below:
Cookie c = new Cookie("Test", "123455");
c.setMaxAge(-1);
response.addCookie(c);
Cookie[] allCookie = request.getCookies();
if (allCookie != null)
for (int i =0; i< allCookie.length; i++)
Cookie c = allCookie;
System.out.print (i+" Name:" + allCookie[i].getName());
System.out.print (" Value:" + allCookie[i].getValue());
System.out.print(" Domain: "+allCookie[i].getDomain());
System.out.println(" Path: "+allCookie[i].getPath());
System.out.println(" MaxAge: "+allCookie[i].getMaxAge());
Where is this cookie is saved? Can I see manually if its been added?     Also, the cookie showing(not "Test"), has domain and path as "null". Thanks.

I would recommend you read up on how cookies actually work:
http://www.arachna.com/edu/tutorials/mini/cookies/index.html
The browser is 'in charge' of determining which cookies get sent back to you. To do this, the domain and the path of the URL have to match the ones stored in the cookie(s) locally by the browser. So, the URL will determine what cookies (zero to many) are sent to the server on a particular request. (There are other attributes, such as expiration date, but on a high level, the above should be true).
