This document has been reviewed as part of the transport area review team's

discussion list for information.

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.
