mod_s2s_keepalive: Ignore errors from the local server If a stanza can't be delivered and instead an bounce is generated, the origin of the error, when different from the stanza 'from' should be indicated in the 'by' attribute of the <error>, which we look for here so this doesn't count as a successful ping. An error that does come from the remote means we have connectivity, but probably no XEP-0199 handling. This is fine. We care about connectivity, not protocol.

summary: 'Component round-robin load balancing module'
...

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

This module enables multiple instances of external components to connect
at the same time, and does round-robin load-balancing of incoming
stanzas.

Example
=======

        Component "test.example.com"
            modules_enabled = { "component_roundrobin" }
            -- Other component options such as secrets here
