服务器是nginx的，配置了下面这段代码:
location ~* \.(css|js|apk)$ {
root /usr/local/resources;
expires 12h;
}
用chrome访问可以看到js与css都是 from memory cache 与 from disk cache ，然后状态都是 200。50个请求，1.03秒, 17kb
用firefox访问js与css同样50个请求，但响应是3.x秒2.x秒甚至4.x秒。返回的状态是304,没有像chrome那样读取缓存。返回的内容有1.87MB，每次都是这样
firefox请求头

请问firefox需要设置什么吗？ 还是代码有问题？
