html - 利用 Nginx 的浏览器缓存，重新加载页面时没有 css

Question

我正在尝试遵循 google pagespeed 建议和利用浏览器缓存。为此，我将以下代码放入我的 nginx.conf 文件的服务器 block 中。

location ~*  \.(jpg|jpeg|png|gif|ico|css|js)$ {
    expires 365d;
}

location ~*  \.(pdf)$ {
    expires 30d;
}

它似乎运行良好，页面速度将我的分数从 87/100 提高到 95/100。但是，当我单击我网站的刷新按钮时，它似乎不再加载 css 文件了？缓存不起作用吗？

我得到的错误信息是

Failed to load resource: the server responded with a status of 404 (Not Found)

这是我的整个 nginx.conf 文件

worker_processes 1;

events {

    worker_connections 1024;

}

http {
    include /etc/nginx/mime.types;

    sendfile on;

            expires 30d;
        }

        # Serve a static file (ex. favico)
        # outside /static directory
        location = /favico.ico  {

            root /app/favico.ico;

        }

        # Proxy connections to the application servers
        # app_servers
        location / {

            proxy_pass         http://app_servers;

            proxy_set_header   X-Forwarded-Host $server_name;

        }
    }
}

查看 Fiddler 跟踪或 Chrome 开发工具。

304 表示服务器响应“未修改，使用您的本地缓存”。如果您清除浏览器缓存或执行 Shift + 刷新，您将获得 200 以及文件正文。相反，304 的主体长度为零。
