Forward Client IP

•Entrance
Product → Configuration → Edit Configuration → Forward Client IP

•Introduction
This function is to inform upstream servers about the client IP address and other request properties to use non-standard headers
There are three variables for Forward Client IP feature: Cdn-Src-Ip, X-Forwarded-For and Pass original X-Forwarded-For

1. Cdn-Src-Ip: by default, Cdn-Src-Ip is used to obtain the client IP (the IP connection with the CDN node). No configuration is required. The origin can extract the client IP through this header.
2. X-Forwarded-For: when returning to the origin, the header name is X-Forwarded-For, and the client IP value is obtained by Cdn-Src-Ip.
3. Pass original X-Forwarded-For: when the client requests the CDN node, the client will bring its own X-Forwarded-For header, then the CDN will pass through the HTTP header and inform that to the origin.
