The IESG has approved the following document: - 'Guidelines for HTTP-to-CoAP Mapping Implementations' (draft-ietf-core-http-mapping-17.txt) as Proposed Standard This document is the product of the Constrained RESTful Environments Working Group. The IESG contact persons are Alexey Melnikov, Ben Campbell and Alissa Cooper. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-core-http-mapping/ Technical Summary This document provides reference information for implementing a cross- protocol network proxy that performs translation from the HTTP protocol to CoAP (Constrained Application Protocol). This will enable a HTTP client to access resources on a CoAP server through the proxy. This document describes how a HTTP request is mapped to a CoAP request, and then how a CoAP response is mapped back to a HTTP response. This includes guidelines for URI mapping, media type mapping and additional proxy implementation issues. This document covers the Reverse, Forward and Interception cross-protocol proxy cases. Working Group Summary The working group has very good consensus on this document as it is. HTTP mapping aspects raised by future CoAP extensions will then be addressed by these extensions or in separate documents. Document Quality There are multiple implementations of the mapping specified in this document. See the shepherding write-up. Media Type review was requested. See <https://www.ietf.org/mail-archive/ web/media-types/current/msg00817.html>. Personnel Jaime Jiménez is the Document Shepherd. Alexey Melnikov is the Responsible Area Director. RFC Editor Note In Section 8.5 (change section 6.2.4 of [RFC7230] to section 6.5): OLD: If the CoAP server takes a long time in responding, the HTTP client or any other proxy in between may timeout. Further discussion of timeouts in HTTP is available in Section 6.2.4 of [RFC7230]. NEW: If the CoAP server takes a long time in responding, the HTTP client or any other proxy in between may timeout. Further discussion of timeouts in HTTP is available in Section 6.5 of [RFC7230].
