I found the problem: IE 7. I had to grand access to my domain. However, I thought a session is stored on the server, instead of the client? Than why do I have IE grand access to my domain? (http://www.pcwindowstips.com/2007/09/04/how-to-enable-cookies-in-internet-explorer-7/)

会话的工作方式是为站点存储一个会话 cookie，其中包含您的会话 ID.服务器知道您是谁的唯一方法是在每次加载页面时读取会话 ID cookie.所有 $_SESSION 数据都存储在每个用户的服务器上，但必须设置 cookie 以便服务器知道要检索哪些 $_SESSION 数据.

The way sessions work is that a session cookie is stored for the site, which contains your session ID. The only way the server knows who you are is when it reads the session ID cookie on every page load. All of the $_SESSION data is stored on the server for each user, but the cookie must be set for the server to know which $_SESSION data to retrieve.

这也是为什么如果您获得他们的会话 ID cookie，您基本上可以成为"另一个用户.

This is also why you can essentially "become" another user if you obtain their session id cookie.
