CodeIgniter会话cookie域

Question

它出现在下面的cookie设置中,为整个域设置了cookie.例如,如果我在http://subdomain.domain.com上,则会为subdomain.domain.com设置cookie.如果我在domain.com上,则会为domain.com设置cookie.

如果为subdomain.domain.com设置了cookie,那是否意味着subdomain2.domain.com无法从subdomain.domain.com访问cookie？

$config['cookie_prefix']    = "";
$config['cookie_domain']    = "";
$config['cookie_path']      = "/";

Answer 1

域特定cookie仅可在该域上访问.使用".domain.com"作为您的Cookie域,以便能够在所有子域和主域中使用它.
