option specifies an approximate maximal size in bytes of XML stanzas.
For example \verb|{max\_stanza\_size, 65536}|. The default value
is ``\term{infinity}''.
\titem{\{max\_user\_sessions, Max\}} \ind{options!max\_user\_sessions}This
option specifies the maximum number of sessions (authenticated
connections) per user. If a user tries to open more than the maximum
number of allowed sessions, with different resources, the first opened
session will be disconnected. The error ``\term{session replaced}'' is
send to the disconnected session. This value is either a number or
\term{infinity}. For example \verb|{max\_user\_sessions, 10}|. The
default value is \term{10}.
\titem{\{shaper, <access rule>\}} \ind{options!shaper}This option defines a
shaper for the port (see section~\ref{sec:configshaper}). The default value
is ``\term{none}''.
