Question

我使用FireFox的HTTP Live标头来查看标题。我在mydomain.com上写了一个脚本，它只是设置一个测试cookie。我认为当我们向裸露的网址http://mydomain.com/script.php发送请求时，Cookie会被发送到所有子域。但是当我向http://www.mydomain.com/script.php发送请求时，浏览器在标头请求中没有发送cookie。怎么样？

http://mydomain.com/script.php

新浏览器是不是像以前一样发送标题？

Answer 1

添加域选项domain=.mydomain.com。这对应于setcookie的域参数，这在那里解释：

“使cookie可用那么example.com的子域名就可以了将其设置为'.example.com'。“

Cookie：标头在预期时未见
