Question

我已经将下面的nginx缓存定义为配置。

    location ~* \.(ico|css|js|gif|jpe?g|png)$ {

        proxy_cache folder;
        proxy_cache_min_uses 1;
        proxy_cache_valid 200 60m;
        proxy_hide_header Set-Cookie;
        proxy_ignore_headers Set-Cookie;

        proxy_cache_valid any 0;

        proxy_cache_key $scheme$proxy_host$host$request_uri;
        client_max_body_size 50m;

        proxy_pass http://upstream_folder;

        proxy_http_version 1.1;
        proxy_buffers 4 256k;
        proxy_buffer_size 128k;
        proxy_busy_buffers_size 256k;
        proxy_send_timeout 300s;
        proxy_read_timeout 300s;
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-For $x_forwareded_for;

        keepalive_timeout 5;
    }

我不想缓存非200个请求静态内容，如img / css / js / gif等。

但是对于具有302重定向响应的下面的请求，nginx会缓存它。请告诉我我的ningx配置有什么问题。以及如何避免对图像或任何静态内容进行302响应缓存。

    curl 'https://localhost:9000/hello.jpg' --verbose
