我刚刚重新安装了我的机器以删除旧的依赖项并以更适当的方式安装东西,我刚刚意识到缓存现在似乎不正确。
图像的标题如下:
cache-control:max-age=300
content-type:image/png
date:Wed, 09 Nov 2016 13:17:50 GMT
expires:Wed, 09 Nov 2016 13:22:50 GMT

server:nginx/1.11.5
status:200
你可能看到,有效期是5m
。然而,缓存块设置为:
location /assets {
alias /var/www/f13/content/themes/lechuck/assets;
access_log off;
expires max;
}
应该如此10y
。
以下是整个文件:

知道可能会发生什么事吗?
答案1
似乎来自基于正则表达式的位置之一拦截了请求。
尝试注释除 /assets 之外的所有位置,然后逐个取消注释并重新验证缓存控制值。
每次编辑后不要忘记调用“nginx -t”和“nginx -s reload”。
答案2
我发现在使用 Wordpress 时需要手动重写过期标头,我写了一个教程,这里您需要 headers_more 模块,这通常需要从源代码构建 Nginx,我有相关说明这里。
我知道 SF 想要帖子中的信息,所以就给你了。不过你最好阅读教程以获得更好的背景信息。
构建 Nginx
cd /home/ec2-user
mkdir nginx-build
cd nginx-build
service nginx stop
