Question

我有一个名为cdn.domain.com的子域名，我从中提供CSS，JS和一些图像。当我运行谷歌浏览器audit时，它表示我可以通过从无cookie域提供这些文件来提高速度。我在互联网上搜索过，发现大部分是这样的：

<FilesMatch "\.(js|css|jpg|png|jpeg|gif|xml|json|txt|pdf|mov|avi|otf|woff|ico|swf)$">
    RequestHeader unset Cookie
    Header unset Cookie
    Header unset Set-Cookie
</FilesMatch>

但是当我在根目录中将其添加到我的.htaccess时，我发现我的请求没有变化，当我将其添加到cdn.domain.com的.htaccess时，也没有任何反应。当我查看请求标头时，我总是看到：

Cookie:__utma=124771992.1672641002.1393489852.1393489852.1393489852.1; __utmz=124771992.1393489852.1.1.utmcsr=(direct)|utmccn=(direct)|utmcmd=(none); cve=7%2BOFANPFY6bPsm9274j8hJIz%2BPvLQRT%2FJZG9ftr2o7c%3D; cvp=dNuYumBN%2F642JaRgONUeEq1upp2y%2F%2FtDjt%2BBbV87W%2BA%3D

子域是全局域的子文件夹。全局和子域都有这个.htaccess：

我在这里做错了什么？

这是manual page for setcookie()对$domain参数的解释：

将域设置为“www.example.com”将使Cookie可用在www子域和更高的子域中。 可用的Cookie 较低的域名，例如'example.com'将可用于更高级别子域名，例如“www.example.com”。旧版浏览器仍然存在实施已弃用的»RFC 2109可能需要领先。至匹配所有子域。

这意味着在现代浏览器中（我认为这几乎意味着在实践中），domain.com的任何cookie集都将由浏览器发送回cdn.domain.com。这就是cookie规范的工作方式，我认为没有一个干净的解决方案。

理想情况下，您的无Cookie域名应使用完全不同的顶级域名;或者您的网站应该托管在子域中，例如www.domain.com，这样您就可以对Cookie进行微调。我想在这一点上没有一个是合理的选择，所以你可能不得不忍受它。
