\ind{modules!\modclientstate{}}\ind{Client State Indication}
\ind{protocols!XEP-0352: Client State Indication}
This module allows for queueing or dropping certain types of stanzas
when a client indicates that the user is not actively using the client
at the moment (see \xepref{0352}). This can save bandwidth and
resources.
Options:
\begin{description}
\titem{drop\_chat\_states: true|false} \ind{options!drop\_chat\_states}
Drop most "standalone" Chat State Notifications (as defined in
\xepref{0085}) while a client indicates inactivity. The default value
is \term{false}.
\titem{queue\_presence: true|false} \ind{options!queue\_presence}
While a client is inactive, queue presence stanzas that indicate
(un)availability. The latest queued stanza of each contact is
delivered as soon as the client becomes active again. The default
value is \term{false}.
\end{description}
Example:
\begin{verbatim}
modules:
...
mod_client_state:
drop_chat_states: true
queue_presence: true
...
\end{verbatim}
