note 8592 deleted from setcookie by jmcastagnetto

I have set the following cookie in a php page: $lifetime = mktime(12, 50, 30, 6, 20, 2010); setcookie("CustomCustomer", $custom_customer, $lifetime); The cookie does indeed get set and can be called and displayed on the page. However, when I kill Netscape and then start up Netscape again, the cookie is removed. It seems as though it is not handling the expiration properly. I've tired all sorts of variations of the above example with no success. Any advice would be greatly appreciated. Thanks. Chris
