嗨Sebastian，
我认为如果没有JavaScript，你无法检测到这一点。
如果有人去其他地方，你的服务器没有得到通知。
你只能通过JavaScript试试。
推荐人：
我没看到Referer标题如何帮助你。
发送到下一个网站（如果发送的话）。
会话：
也没有去。
会话只不过是服务器上的一段数据
通过一个访问者链接到某个访问者PHPSESSID（通过cookie / url / form）。
我看不出他们如何帮助你。
所以底线，运气不好。
您需要JavaScript（或其他一些客户端技术，如JAVA
小程序）。
问候，
Erwin Moller

纠正我，如果我错了，但如果用户离开他的网站，然后返回
refer会指向另一个网站。因此，检测参考价值可以
可能有助于解决问题。
@Sebastian
请参考用户发送的信息，所以不可信任。您可以使用
来改善网站的功能，但不要将它用于任何
关键检查（如访问控制等）。
当用户输入网址
或在新标签页中打开新窗口时，也可以将参考设置为空（不确定）关于那个。）
最好的问候

甚至Javascript也不一定告诉你。关闭浏览器，例如，
将不会执行javascript。

Can this be done without client-side scripting? I thought sessions
might be the answer but after some testing found that sometimes the
old session data remained even after the user left the site and
returned. Just had an idea, though. Perhaps I could access the users
Referrer header?

Referrer header?Hi Sebastian,
I think you cannot detect this without JavaScript.
If somebody goes somewhere else, your server is not notified.
You can only try this via JavaScript.
Referer:
And I don''t see how the Referer header can help you out.
It is send to the next site (if send at all).
Session:
No go either.
A Session is nothing more than a piece of data on the server that is
linked to a certain visitor via a PHPSESSID (via cookie/url/form).
I don''t see how they can help you with this.
So bottomline, bad luck.
You need JavaScript (or some other clientside technology, like an JAVA
applet).
Regards,
Erwin Moller

refer would point to the other site. So detecting refer value could
possibly help the problem.
@Sebastian
Refer it''s send by the user, so can''t be trusted. You can use it
to improve the functionality of the site, but don''t use it to any
critical checks (like access controll ect.).
It''s also possible, that refer will be empty, when user types in the url
or opens new window in ''new tab'' (not sure about that though).
best regards

And even Javascript doesn''t necessarily tell you. Closing the browser,
for instance, will not execute javascript.
