mod_sasl2_fast: Fix harmless off-by-one error (invalidates existing tokens!) Problem: This was causing the key to become "<token>--cur" instead of the expected "<token>-cur". As the same key was used by the code to both set and get, it still worked. Rationale for change: Although it worked, it's unintended, inconsistent and messy. It increases the chances of future bugs due to the unexpected format. Side-effects of change: Existing '--cur' entries will not be checked after this change, and therefore existing FAST clients will fail to authenticate until they attempt password auth and obtain a new FAST token. Existing '--cur' entries in storage will not be cleaned up by this commit, but this is considered a minor issue, and okay for the relatively few FAST deployments.

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
