This is a W3C Working Draft for review by W3C members and other interested parties. It is a draft document and may be updated, replaced or obsoleted by other documents at any time. It is inappropriate to use W3C Working Drafts as reference material or to cite them as other than "work in progress". A list of current W3C technical reports can be found at http://www.w3.org/TR. This document has been produced as part of the W3C HTTP-ng Activity. This is work in progress and does not imply endorsement by, or the consensus of, either W3C or members of the HTTP-ng Protocol Design Working Group. We expect the document to evolve as we get more data from the Web Characterization Group describing the current state of the Web. This document describes a binary `on-the-wire' protocol to be used when sending HTTP-ng operation invocations or terminations across a network connection.
