Using the HTTP/HTTPS listener, the origin server can directly get the real client IP from the
X-Real-IP or X-Forwarded-For field in the HTTP request header. This feature is enabled by default.It can also be customized as instructed in HTTP/HTTPS Listener Management. If there is an intermediate linkage such as CLB or self-built Nginx between the origin server and the program, you need to configure it by yourself to prevent the field from being overwritten by the intermediate linkage.
