An administrator wants to remove the X-Powered-By header from responses sent to clients. Which directive should be used?

proxy_hide_header X-Powered-By;

proxy_set_header X-Powered-By "";

An administrator defines proxy_set_header X-Custom "value" in the server context. What happens if a location block also defines its own proxy_set_header directive?

NGINX will throw a configuration error

The server-level directive is inherited and the location-level directive is ignored

The location block's proxy_set_header directives replace the server-level ones entirely

Both directives are merged, with the location-level one taking precedence for the same header

An NGINX reverse proxy serves two upstream applications: one expects the X-Forwarded-Proto header to be set to https when the original request was HTTPS, and the other expects it to be http. The administrator needs to set this header differently based on the original request's protocol. Which approach is the most maintainable?

Use proxy_set_header X-Forwarded-Proto $scheme;

Use add_header X-Forwarded-Proto $scheme;

Use an if block to check $scheme and set the header accordingly.

Use a map directive to set a variable based on $scheme, then use proxy_set_header X-Forwarded-Proto $scheme;
