m32283 Next segment signaling via HTTP HEAD requests – TuC

Summary: Proposes the http head request to be used instead of http header extension. Header extension is part of HTTP1.1. Also the current solution doesn’t require a new request, while head request needs a new separate request. The header extension also doesn’t require the CDN to take any specific action, while head request needs a response by CND.

Resolution: Move this section of TuC to SAND CE to further evaluate.
