Subject: [CDNi] Including cdn-path in RI responses?

Colleagues,

While doing some editing on the Redirection Interface draft, I noticed that we currently say that can-path MUST be included in both RI requests and RI responses.

Including it in requests is fine and necessary for loop detection.

However, I can’t think of a good reason to include it in responses, except for debugging purposes, and in a production environment including can-path in responses may expose information to a uCDN (business relationships between a dCDN and other CDNs) that the dCDN may not want to expose.

Unless anyone can provide a good reason why cdn-path MUST be included in RI responses, I plan to change the document to say that can-path MUST be included in RI requests and MAY be included in RI responses along with a note that including it in responses may expose business relationships so need consideration before doing so.

Any objections?

Thanks
Ben
