  "abstract": "This document defines the CDN-Loop request header field for HTTP.  CDN-Loop addresses an operational need that occurs when an HTTP request is intentionally forwarded between Content Delivery Networks (CDNs), but is then accidentally or maliciously re-routed back into the original CDN causing a non-terminating loop.  The new header field can be used to identify the error and terminate the loop.",
