/** * We try to set the correct cookie domain. If you are experiencing problems * try commenting out the code below or specifying the cookie domain by hand. */ if (isset($_SERVER['HTTP_HOST'])) { $domain = '.'. preg_replace('`^www.`', '', $_SERVER['HTTP_HOST']); // Per RFC 2109, cookie domains must contain at least one dot other than the // first. For hosts such as 'localhost', we don't set a cookie domain. if (count(explode('.', $domain)) > 2) { ini_set('session.cookie_domain', $domain); } } てのが追加されてましたが、これってどういう挙動なんでしょうか？
