syntax: uwsgi_hide_header name
context: http, server, location
By default, Nginx does not pass "X-Accel-..." headers from the uWSGI process back to the client. This directive can be used to hide other headers as well.
If the "X-Accel-..." headers must be provided, then it is necessary to use directive uwsgi_pass_header to force them to be returned to the client.
