mod_conversejs: Serve base app at / This makes things slightly less awkward for the browser to figure out which URLs belong to a PWA. The app's "start URL" was previously without the '/' and therefore was not considered within the scope of the PWA. Now the canonical app URL will always have a '/'. Prosody/mod_http should take care of redirecting existing links without the trailing / to the new URL. If you have an installation at https://prosody/conversejs then it is now at https://prosody/conversejs/ (the first URL will now redirect to the second URL if you use it). The alternative would be to make the PWA scope include the parent, i.e. the whole of https://prosody/ in this case. This might get messy if other PWAs are provided by the same site or Prosody installation, however.

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

::: {.alert .alert-info}
This module discards certain kinds of stanzas that are unnecessary to deliver to inactive clients. This is technically against the XMPP specification, and has the potential to cause bugs. However it is being used by some people successfully, and reduces the overall bandwidth usage for mobile devices.
On the other hand it does not save battery usage in a relevant way compared to other `csi` modules.
Consider using [mod_csi_simple][doc:modules:mod_csi_simple] that is incuded in prosody since Version 0.11.

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
=============

  ----- -------
  0.11   Works
