Question

这是我的nginx配置（使用nginx 1.16.1）：

user  nginx;
worker_processes  auto;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;


events {
    worker_connections  100000;
}


http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format upstream_time '$remote_addr - $remote_user [$time_local] '
                             '"$request" $status $body_bytes_sent '
                             '"$http_referer" "$http_user_agent"'
                             'rt=$request_time uct="$upstream_connect_time" uht="$upstream_header_time" urt="$upstream_response_time"';

        listen 443 ssl http2;

        server_name example.com;

        root /html;
        index /;

        error_page 404 /404.html;
        error_page 500 /500.html;
        error_page 502 =503 /maintenance.html;

        location = /404.html {
            add_header x-nginx-cache-status $upstream_cache_status always;
        }

        location ~^/([a-zA-Z0-9/]+)$ {
            set $product_id $1;
            rewrite ^ /product?id=$product_id break;

            proxy_intercept_errors on;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $remote_addr;
            proxy_set_header Host $host;
            proxy_set_header REQUEST_URI $request_uri;

            error_log /var/log/nginx/error.log;
            access_log /var/log/nginx/access.log;
        }
    }
}

使用此配置，我可以看到404s实际上是第一个请求后的缓存HIT，但是它并未按设置保存在nginx_cache文件夹中。

作为200个响应的其他请求被适当地缓存并按预期方式保存到磁盘。

我也尝试将相同的缓存配置添加到location = /404.html块中，但这对文件是否保存到磁盘没有任何影响。

我猜想这与使用proxy_intercept_errors和error_page覆盖错误页面有关，因此nginx不再使用我设置的参数对其进行缓存。

有没有办法做到这一点？

Nginx不将缓存的404保存到磁盘
