Client IP Forwarding specifies the HTTP request header used to pass client IP information to your origin. Choose the option your origin application or logging system expects.
| Option | Behavior | When to use |
|---|---|---|
Cdn-Src-Ip |
Passes the client IP address in the Cdn-Src-Ip request header. This is the default option. |
Your origin reads Cdn-Src-Ip. |
X-Forwarded-For |
Passes the client IP address obtained by CDNetworks in the X-Forwarded-For request header. |
Your origin or logging system reads X-Forwarded-For. |
| Preserve Original X-Forwarded-For | Passes the incoming X-Forwarded-For header and its original value to the origin, if present. |
Your application needs to retain the incoming X-Forwarded-For value. |
