Well-known URIs for the WebSocket Protocol
draft-bormann-hybi-ws-wk-00
Abstract
RFC 5785 defines a path prefix, "/.well-known/", that can be used by
well-known URIs, specifically for the "http" and "https" URI schemes.
The present memo formally updates RFC 6455, which defines the URI
schemes defined for the WebSocket Protocol, to extend the use of
these well-known URIs to those URI schemes.
Status of This Memo
This Internet-Draft is submitted in full conformance with the
provisions of BCP 78 and BCP 79.

1. Introduction
[RFC5785] defines a path prefix, "/.well-known", that can be used by
well-known URIs, as well as an IANA registry for URI suffixes to be
used with this path prefix for forming well-known URIs.
In [RFC5785], this mechanism is specifically defined for the "http"
and "https" URI schemes (now defined in [RFC7230]). Other URI
schemes such as "coap" and "coaps" [RFC7252] have since picked up
this mechanism, sharing the registry of URI suffixes with that for
HTTP(S).
[RFC6455], which defines the URI schemes defined for the WebSocket
Protocol, "ws" and "wss", does not define the use of well-known URIs
for these URI schemes.
The present memo formally updates [RFC6455], to extend the use of
[RFC5785] well-known URIs to the URI schemes "ws" and "wss".
Well-known URIs for "ws" and "wss" share the registry for URI
suffixes established by [RFC5785]; no change is necessicated by the
present memo in the registry or its IANA considerations.
2. IANA considerations
This memo does not require any IANA actions.
3. Security considerations
The Security Considerations of [RFC5785] apply and need to be
considered for all well-known URIs.
It has always been possible to form "ws" and "wss" URIs in such a way
that they map to well-known HTTP(S) URIs when using the procedure in
Bormann Expires November 12, 2017 [Page 2]
Internet-Draft Well-known URIs for the WebSocket Protocol May 2017
Section 4 of [RFC6455], so no new security considerations about this
are created by now formally making the well-known URI mechanism
available for "ws" and "wss", as well.
However, with well-known URIs becoming available for the WebSocket
protocol, applications that want to define well-known URI suffixes
specifically for WebSocket use also need to consider whether the
resources becoming available under the equivalent HTTP(S) URI formed
by Section 4 of [RFC6455] pose any information disclosure or other
security considerations.
