在Javascript重定向之前设置cookie-SettingacookiebeforeJavascriptRedirection

You're absolutely correct - the explanation you propose isn't possible. Assuming the browser is loading the page from your site that sends the COOKIE header, it will be set, and Javascript can't directly interfere with this.

你是绝对正确的 - 你提出的解释是不可能的。假设浏览器正在从您的站点加载发送COOKIE标头的页面,它将被设置,Javascript不能直接干扰它。

So the problem is elsewhere - the first thing I would test is whether the COOKIE header is actually being sent, whether it's being set (look in your browser's security/privacy panel), and then whether your code for checking if it's been set is functioning correctly.

所以问题出在其他地方 - 我要测试的第一件事是COOKIE标头是否实际发送,是否正在设置(查看浏览器的安全/隐私面板),然后检查是否已设置的代码是否正常运行正确。

As you suspected, the COOKIE should be sent in the header when the visitor hits your page, so google optimizer shouldnt be affecting this..

如您所料,当访问者点击您的网页时,COOKIE应该在标题中发送,因此Google优化工具不应该影响这一点。

You may want to double check that you are setting the COOKIE, you can use firebug or similar for this (in the Net tab).

您可能想要仔细检查您是否正在设置COOKIE,您可以使用firebug或类似的(在Net选项卡中)。
