mod_ping_muc: Delay ping a configurable amount of time If a server is restarting, checking immediately before it has a chance to complete its restart and get ready would often fail, preventing the possibility of transparent restarts as supported by Prosody's mod_muc. Reconnecting immediately when a connection is closed for being idle, or because the remote server is trying to reclaim some resources, is also counter-productive as the connection may fail. Also, if there is some Internet routing problem affecting s2s, it may help to wait a bit before checking, in case the problem resolved itself in the mean time.

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

[PKIX over Secure HTTP (POSH)][rfc7711] describes a method of
securely delegating a domain to a hosting provider, without that hosting
provider needing keys and certificates covering the hosted domain.

# Validating

This module performs POSH validation of other servers. It is *not*
needed to delegate your own domain.

# Delegation

You can generate the JSON delegation file from a certificate by running
`prosodyctl mod_s2s_auth_posh /path/to/example.crt`. This file needs to
be served at `https://example.com/.well-known/posh/xmpp-server.json`.
