After servicing this request the dCDN will not use the specified data without first re-validating it using, for example, an "If-None-Match" HTTP request. The dCDN need not erase the associated data. purge A request for the dCDN to erase metadata or content. After servicing the request, the specified data MUST NOT be held on the dCDN (the dCDN should re-acquire the metadata or content from uCDN if it needs it). Specification Required Kevin Ma, Sanjay Mishra emeta The dCDN was unable to acquire metadata required to fulfil the request. econtent The dCDN was unable to acquire content (CT/T preposition commands only). eperm The uCDN does not have permission to issue the CI/T Command (for example, the data is owned by another CDN). ereject The dCDN is not willing to fulfil the CI/T Command (for example, a preposition request for content at a time when the dCDN would not accept Request Routing requests from the uCDN). ecdn An internal error in the dCDN or one of its downstream CDNs. ecancelled The uCDN cancelled the request. eunsupported The Trigger Specification contained a "type" that is not supported by the dCDN. No action was taken by the dCDN other than to create a Trigger Status Resource in state "failed".

All directive names defined in the logging file are case-insensitive as per the basic ABNF (). Each specification that defines a new CDNI Logging directive needs to contain a description for the new directive with the same set of information as provided in Section 3.3 of (i.e., format, directive value and occurrence). version UUID claimed-origin established-origin remark record-type fields SHA256-hash Specification Required Kevin Ma Version values are to be allocated with a format of NAMEFORMAT (see Section 3.1 of ). All version values defined in the logging file are case-insensitive as per the basic ABNF (). cdni/1.0 CDNI Logging File version 1.0 as specified in Specification Required Kevin Ma Record-types are to be allocated with a format of NAMEFORMAT (see Section 3.1 of ). All record-types defined in the logging file are case-insensitive as per the basic ABNF (). Each specification that defines a new record-type needs to contain a description for the new record-type with the same set of information as provided in Section 3.4.1 of . This includes: o a list of all the CDNI Logging fields that can appear in a CDNI Logging Record of the new record-type o for all these fields: a specification of the occurrence for each Field in the new record-type o for every newly defined Field, i.e., for every Field that results in a registration in the CDNI Logging Field Names Registry: a specification of the field name, format and field value. cdni_http_request_v1 CDNI Logging Record version 1 for content delivery using HTTP cdni_http_request_v2 Extension to CDNI Logging Record version 1 for content delivery using HTTP, to include URI Signing Logging fields Specification Required Kevin Ma Field names are to be allocated with a format of NHTABSTRING (see Section 3.1 of ).

The reason field may be used to provide more details about the source of the error. 500 <reason> (see Description) Generic error-code for dCDN errors where the dCDN is aware that it has erred or is incapable of satisfying the RI request for some reason. The reason field may be used to provide more details about the source of the error. 501 Unable to retrieve metadata The dCDN is unable to retrieve the metadata associated with the content requested by the UA. This may indicate a configuration error or that the content requested by the UA does not exist. 502 Loop detected The dCDN detected a redirection loop (see Section 4.8 of ). 503 Maximum hops exceeded The dCDN detected the maximum number of redirection hops exceeding max-hops (see Section 4.8 of ). 504 Out of capacity The dCDN does not currently have sufficient capacity to handle the UA request. 505 Delivery protocol not supported The dCDN does not support the (set of) delivery protocols indicated in the CDNI Metadata of the content requested by the UA. 506 Redirection protocol not supported The dCDN does not support the requested redirection protocol. This error-code is also used when the RI request has the dns-only flag set to True and the dCDN is not supported or is not prepared to return an RT of a surrogate directly.
