A company wants to set the X-Forwarded-Host header to the original Host header only when the request comes from a specific client IP range. Which configuration approach is most appropriate?

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

Use proxy_set_header X-Forwarded-Host $host;

Use add_header X-Forwarded-Host $host;

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

An NGINX reverse proxy serves two upstream applications under different locations: /app1 and /app2. The security team requires that the X-Frame-Options header be set to DENY for all responses, but the /app2 team wants to override it to SAMEORIGIN for their responses. The administrator adds add_header X-Frame-Options DENY; in the http block and add_header X-Frame-Options SAMEORIGIN; in the location /app2 block. What will be the result?

Responses from /app2 will have both DENY and SAMEORIGIN headers.

Responses from /app1 will have DENY, and responses from /app2 will have SAMEORIGIN.

Responses from both locations will have SAMEORIGIN because the location-level directive is inherited upward.

Responses from both locations will have DENY because the http block takes precedence.
