Research direction
Examine the existing XForwardedHeadersFilter or similar classes in the spring cloud gateway module. Understand the current 'append' and 'disabled' modes. Implement a new mode that adds X Forwarded * headers only if they are not already present. Follow the existing filter pattern and ensure the change works for both MVC and WebFlux setups.
