Origin-Pull Request Headers Carrying Client IP

Last updated: 2024-10-24 10:34:23

Overview
If you need to collect the client IP information within the origin and distinguish it by service provider source, EdgeOne supports placing the client IP information in a custom HTTP header and returning it to the business origin when the X-Forwarded-For header or other standard headers are not applicable.
Note:
For default headers carried in EdgeOne origin-pull requests, see Default HTTP Response Headers. For modification of the origin-pull request header, see Modifying HTTP Origin-Pull Request Headers.
