Nginx proxy_hide_header

Syntax:		proxy_hide_header field;
Default:	—
Context:	http, server, location

By default, nginx does not pass the header fields “Date”, “Server”, “X-Pad”, and “X-Accel-...” from the response of a proxied server to a client. The proxy_hide_header directive sets additional fields that will not be passed.
