This API is work-in-progress and is subject to breaking changes.
CDN-Loop Header filter config. See the configuration overview for more information.
(string, REQUIRED) The CDN identifier to use for loop checks and to append to the CDN-Loop header.
RFC 8586 calls this the cdn-id. The cdn-id can either be a pseudonym or hostname the CDN is in control of.
cdn_id must not be empty.
(uint32) The maximum allowed count of cdn_id in the downstream CDN-Loop request header.
The default of 0 means a request can transit the CdnLoopFilter once. A value of 1 means that a request can transit the CdnLoopFilter twice and so on.
