<section1 topic='Introduction' anchor='intro'>
|
|
|
|
<p>Unlike for XMPP connections via TCP as specified in &rfc6120;,
|
|
there exists no specificiation of implicit connection endpoints for
|
|
XMPP over WebSocket (&rfc7395;). As a result, XMPP services which
|
|
whish to provide WebSocket connectivity need to announce their
|
|
WebSocket endpoints, so that clients are able to discover them (RFC
|
|
7395 § 4). This XEP fills this gap. It eventually enables, under
|
|
certain conditions, XMPP services to provide WebSocket connectivty,
|
|
without resorting to &xep0156; nor requiring manual configuration by
|
|
the user.</p>

<section1 topic='Implicit XMPP WebSocket Endpoints' anchor='reqs'>
|
|
|
|
<p>The following implicit XMPP WebSocket endpoints are specified:</p>
|
|
<ul>
|
|
<li>wss://<xmpp-service-name>:5443/ws</li>
|
|
<li>ws://<xmpp-service-name>:5443/ws</li>
|
|
<li>wss://<xmpp-service-name>/ws</li>
|
|
<li>ws://<xmpp-service-name>/ws</li>
|
|
</ul>
|
|
|
|
<p>TODO: Use implicit endpoints only if no other endpoints were
|
|
discovered?</p>

|
<section1 topic='Implementation Notes' anchor='impl'>
|
|
|
|
<p>Implementations should note that due this XEP, the collection of
|
|
potential endpoints may contain duplicates. This is because the
|
|
implicit WebSocket connection endpoints defined herein may match the
|
|
ones that where discovered (RFC 7395 § 4, XEP-0156). Implementations
|
|
may want to ensure that no such duplicates exist.</p>
|
|
|
|
<p>Furthermore, implementations attempting to connect to the
|
|
discovered endpoints serially, as opposed to concurrently, may use
|
|
the implicit endpoints only as last resort.</p>

|
|
<section1 topic='Security Considerations' anchor='security'>
|
|
|
|
<p>Since the implicit WebSocket connection endpoints are defined to
|
|
include the XMPP service name, the verification required when using
|
|
the secured variant of the WebSocket transport provides the
|
|
necessary security.</p>
