mod_http_oauth2: Advertise the currently supported id_token signing algorithm This field is REQUIRED. The algorithm RS256 MUST be included, but isn't because we don't implement it, as that would require implementing a pile of additional cryptography and JWT stuff. Instead the id_token is signed using the client secret, which allows verification by the client, since it's a shared secret per OpenID Connect Core 1.0 § 10.1 under Symmetric Signatures. OpenID Connect Discovery 1.0 has a lot of REQUIRED and MUST clauses that are not supported here, but that's okay because this is served from the RFC 8414 OAuth 2.0 Authorization Server Metadata .well-known endpoint!

summary: Drop chat states from messages to inactive sessions
...

Introduction
============

Some mobile XMPP client developers consider [Chat State
Notifications](http://xmpp.org/extensions/xep-0085.html) to be a waste
of power and bandwidth, especially when the user is not actively looking
at their device. This module will filter them out while the session is
considered inactive. It depends on [mod\_csi](/mod_csi.html) for
deciding when to begin and end filtering.

Configuration
=============

There is no configuration for this module, just add it to
modules\_enabled as normal.

Compatibility
=============

  ----- -------
  0.9   Works
