为什么不关闭标签页删除会话Cookie？ [英] Why Doesn't Closing A Tab Delete A Session Cookie?

问题描述

我使用基于会话的Cookie与我的网站。令我完全惊讶的是，我注意到如果我设置了一个会话cookie（不是持久性cookie），关闭一个选项卡，然后重新连接到网站，会话cookie仍然存在。这不是我想象的，实际上。我希望会话cookie被删除。

I'm using session-based cookies with my website. To my complete surprise, I noticed if I set a session cookie (not a persistent cookie), close a tab, and then reconnect to the site, the session cookies are still there. That's not what I would have expected, actually. I would have expected the session cookies to be deleted.

如果您关闭浏览器，会话Cookie会被删除，为什么不关闭标签以获得相同的结果？

If you close the browser, a session cookie is deleted, so why not closing a tab to have the same result?

因此，我使用PHP5和jQuery。有什么我可以做的，当一个标签页关闭我可以解决这个会话问题？不幸的是，BODY标签上的onbeforeunload事件在这里没有用处，因为当您点击远离某个网页时，它会触发该事件，而不只是关闭标签页。

Therefore, I'm using PHP5 and jQuery. Is there anything I can do such that when a tab is closed I can fix this session issue? Unfortunately the onbeforeunload event on the BODY tag is not useful here because when you click away from a page it fires that event, not just closing a tab.

推荐答案

会话cookie是每个进程不是每个窗口。因此，即使您选择了New Window，仍然会得到相同的会话ID。这种行为是有道理的。您不希望用户每次在浏览您的网站时打开新窗口时重新登录。

The session cookie is per-process not per window. So even if you selected New Window you'd still get the same session id. This behavior makes sense. You wouldn't want a user to re-sign in each time they opened a new window while browsing your site.

我不知道任何真正的方式围绕这个。

I'm not aware off hand of any real way around this.
