mod_http_oauth2: Implement stateless dynamic client registration Replaces previous explicit registration that required either the additional module mod_adhoc_oauth2_client or manually editing the database. That method was enough to have something to test with, but would not probably not scale easily. Dynamic client registration allows creating clients on the fly, which may be even easier in theory. In order to not allow basically unauthenticated writes to the database, we implement a stateless model here. per_host_key := HMAC(config -> oauth2_registration_key, hostname) client_id := JWT { client metadata } signed with per_host_key client_secret := HMAC(per_host_key, client_id) This should ensure everything we need to know is part of the client_id, allowing redirects etc to be validated, and the client_secret can be validated with only the client_id and the per_host_key. A nonce injected into the client_id JWT should ensure nobody can submit the same client metadata and retrieve the same client_secret

summary: Limit presence stanzas to save traffic
...

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

For most people 'presence' (status changes) of contacts make up most of
the traffic received by their client. However much of the time it is not
essential to have highly accurate presence information.

This module automatically cuts down on presence traffic when clients
indicate they are inactive (using the [CSI protocol](mod_csi.html)).

This is extremely valuable for mobile clients that wish to save battery
power while in the background.

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

Just load the module (e.g. in modules\_enabled). There are no
configuration options.

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

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