A convention for URIs operating a HTTP-CoAP reverse proxy
draft-bormann-core-cross-reverse-convention-00
Abstract
CoAP is a RESTful transfer protocol for constrained nodes and
networks. In many applications, CoAP will be used via cross-protocol
proxies from HTTP clients. HTTP client libraries may make it hard to
operate an HTTP-CoAP forward proxy by not providing a way to put a
CoAP URI on the HTTP Request-Line; reverse-proxying may therefore
lead to wider applicability of a proxy. This specification will
define a convention for URIs operating such a HTTP-CoAP reverse
proxy.
The current version of this specification is a placeholder only. It
is meant to pick up
http://trac.tools.ietf.org/wg/core/trac/ticket/259 and provide a home
for its considerations. It might be merged with other documents
later.

Internet-Draft CoAP reverse cross-proxy convention December 2012
1. Introduction
(see abstract for now)
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in RFC 2119, BCP 14
[RFC2119] and indicate requirement levels for compliant CoAP
implementations.
In this document, the term "byte" is used in its now customary sense
as a synonym for "octet".
Where bit arithmetic is explained, this document uses the notation
familiar from the programming language C, except that the operator
"**" stands for exponentiation.
