我在JS中编写了一个脚本，它将检索用户的流量源并将该值存储在cookie中。
除了三页之外的所有页面都有效。如果用户的登录页面是例如www.example.com/example1,www.example.com/example2或www.example.com/example3，则cookie仅存储在这些页面上。我没有看到在chrome上的开发人员工具中看到它，但是当我编写document.cookie时，我确实看到了我创建的cookie。我也在设置中看到它。
但如果我要导航到另一个页面，它就不会被存储。
它可以在所有其他页面上正常工作，用户进入登录页面并且cookie在整个会话期间保持存储。除上述页面外。
所有页面的主机名都相同。
有什么想法吗？
