Does Nginx show X-Accel headers in response?

Question

I try disabling Fast CGI buffering by setting X-Accel-Buffering: no header but don't see this header in Nginx response. Is it by design or there's something wrong with my Nginx config? I don't have fastcgi_ignore_headers directive.

By default, nginx does not pass the header fields “Status” and “X-Accel-...” from the response of a FastCGI server to a client. See [this link](http://nginx.org/en/docs/http/ngx_http_fastcgi_module.html#fastcgi_hide_header) — Richard Smith, Oct 29 '18 at 10:40

By default, nginx does not pass the header fields “Status” and “X-Accel-...” from the response of a FastCGI server to a client.

To pass it, you will have to add fastcgi_pass_header (X-Accel-Buffering) in nginx config file. Like

location ~ \.php$ {
....
fastcgi_pass_header "X-Accel-Buffering";
....
}
