error_log /var/log/nginx/error.log;
pid /run/nginx.pid;
include /usr/share/nginx/modules/*.conf;
events {
    worker_connections 1024;
}
http {
    sendfile            on;
    tcp_nopush          on;
    tcp_nodelay         on;

    include             /etc/nginx/mime.types;
    default_type        application/octet-stream;
    server {
        listen              80;
        server_name         test.mydomain.org;
        root                /etc/nginx/html;
        index   index.html;

        location / {
            add_header 'Access-Control-Allow-Origin' '*';
            add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
            add_header 'Access-Control-Allow-Headers' 'DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Content-Range,Range';
            add_header 'Access-Control-Expose-Headers' 'DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Content-Range,Range';
            add_header 'Cache-Control' 'no-cache';
            default_type text/plain;
            return 200 "$remote_addr";
        }
        # Error page
        error_page  404    /404;
    }
}

Answer 1

您看到的缓存来自浏览器缓存。清除浏览器缓存并在重置位置conf后尝试该页面以包括：

    # kill cache
    add_header Last-Modified $date_gmt;
    add_header Cache-Control 'private no-store, no-cache, must-revalidate, proxy-revalidate, max-age=0';
    if_modified_since off;
    expires off;
    etag off;

这使得绝对确保浏览器或任何中间代理不会缓存发送的输出。

Answer 2

在nginx conf文件中使用此配置

location /path-to-files/ {
directio 0;
}

将绕过操作系统级别的缓存。
