Reviewer: Colin Perkins Review result: Ready This document has been reviewed as part of the transport area review team's ongoing effort to review key IETF documents. These comments were written primarily for the transport area directors, but are copied to the document's authors and WG to allow them to address any issues raised and also to the IETF discussion list for information. When done at the time of IETF Last Call, the authors should consider this review as part of the last-call comments they receive. Please always CC tsv-art@xxxxxxxx if you reply to or forward this review. I have reviewed draft-ietf-httpbis-cdn-loop-01. It defines a new HTTP header that can be used to detect CDN forwarding loops. There are no apparent transport issues. Editorial: The terminology 'The CDN-Loop Request Header' can easily be misread to suggest that the CDN is being requested to loop traffic. Using instead 'The "CDN-Loop" Request Header' might make this clearer. Colin
