Indeed!
Thank you very much for the help. You are right - included /etc/nginx/proxy.conf defines such timeout.
But if I want redefine its values afte inclusion I got error like:
[code][emerg]: "proxy_send_timeout" directive is duplicate in /etc/nginx/sites-enabled/detishop:18
configuration file /etc/nginx/nginx.conf test failed[/code]
Is there way have included common settings and just redefine [b]some[/b] for concrete [b]location[/b] or [b]server[/b]?
