mod_log_ringbuffer: Detach event handlers on logging reload (thanks Menel) Otherwise the global event handlers accumulate, one added each time logging is reoladed, and each invocation of the signal or event triggers one dump of each created ringbuffer.

summary: 'Receives HTTP POST request, parses it and relays it into XMPP.'

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

Sometimes it's useful to have different interfaces to access XMPP.

This module allows sending XMPP
[`<message>`](https://xmpp.org/rfcs/rfc6121.html#message) stanzas via a
simple HTTP API.

Example usage
-------------

    curl http://example.com:5280/msg/user -u me@example.com:mypassword -H "Content-Type: text/plain" -d "Server@host has just crashed!"

This would send a message to user\@example.com from me\@example.com

Details
=======

URL format
----------

    /msg/ [recipient [@host] ].

The base URL defaults to `/msg`. This can be configured via Prosodys
[HTTP path settings][doc:http].

Authentication
--------------

Authentication is done by HTTP Basic.

    Authentication: Basic BASE64( "username@virtualhost:password" )

Payload formats
---------------

Supported formats are:

`text/plain`
:   The HTTP body is used as plain text message payload, in the `<body>`
    element.

`application/x-www-form-urlencoded`
:   Allows more fields to be specified.

`application/json`
:   Similar to form data.

Which one is selected via the `Content-Type` HTTP header.

### Data fields

The form data and JSON formats allow the following fields:

`to`
:   Can be used instead of having the receiver in the URL.

`type`
:   [Message type.](https://xmpp.org/rfcs/rfc6121.html#message-syntax-type)

`body`
:   Plain text message payload which goes in the `<body>` element.

with a very similar API.
