Set Client IP Custom Header

This feature allows the IP address of the requesting client to be added to the request as a custom request header. The name of the request header in which the IP address will be saved is determined by the value assigned to the Header name option. If a header name value is not specified, then this value will be stored in a request header called "True-Client-IP."

Note: This feature allows a customer origin server to find out client IP addresses through a custom request header. If the request is served from cache, then the origin server will not be informed of the client's IP address. Therefore, it is recommended that this feature be used with ADN or assets that will not be cached.

Please make sure that the specified header name does not match any of the following:

• Standard request header names. A list of standard header names can be found in RFC 2616.
• Reserved header names:
  • forwarded-for
  • host
  • vary
  • via
  • warning
  • x-forwarded-for
  • All header names that start with "x-ec" are reserved.
