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

This is an experimental authentication module that does an asynchronous
HTTP call to verify username and password.

Details
=======

When a user attempts to authenticate to Prosody, this module takes the
username and password and does a HTTP GET request with [Basic
authentication][rfc7617] to the configured `http_auth_url`.

Configuration
=============

``` lua
VirtualHost "example.com"
authentication = "http_async"
http_auth_url = "http://example.com/auth"
```

Compatibility
=============

Requires Prosody trunk
