• How to Configure Spring Boot Tomcat
• SpringBoot Common Application Properties
• Tomcat 에서 RemoteIpValue 잘 참고할것. ELB 사용시 특히 server.tomcat.internal-proxies 에 별도 값이 더 필요한지 확인 필요.

• server.forward-headers-strategy=NATIVE 이거 하나로 다 되는 상태 된듯.
• tomcat 뿐만 아니라 undertow 등 다른 웹서버도 가능.
• 안되면 FRAMEWORK 값 사용.
• java - Spring server.forward-headers-strategy NATIVE vs FRAMEWORK - Stack Overflow
• Web on Servlet Stack - 1.2.2. Forwarded Headers
