I have nginx setup as a proxy in front of APACHE, which in turn talks to PHP-FPM.
It turns out, nginx is cutting out (or better to say not passing through) headers that are set directly in PHP via the header('foo: bar') command.
Namely I see the following picture:
PHP I set the following headers: - cache-control - pragma - expires
And I see these if I open the page not through the nginx proxy, but directly through apache.
Now, when I open the page through nginx > all of the above are missing, and cache-control is totally replaced :/
I have the following extra directives in the nginx config, aiming to cache all images and static files for at least 30 days:
tcp_nopush on; tcp_nodelay on; access_log off; expires 30d; keepalive_timeout 30; keepalive_requests 1000; reset_timedout_connection on; client_body_timeout 10; send_timeout 2;
whatever I try does not work > seems like nginx is generally ignoring all headers coming its way from apache. Is there any way around this?
