Introduction
------------

This module gives HTTP access to prosody’s storage mechanism. It uses
normal HTTP verbs and [Basic HTTP
authentication](http://tools.ietf.org/html/rfc2617), so you could call
it RESTful if you like buzzwords.

Syntax
------

To Fetch data, issue a normal GET request

    GET /data[/<host>/<user>]/<store>[/<format>] HTTP/1.1
    Authorization: <base64(authzid:password)>

OR

    PUT|POST /data[/<host>/<user>]/<store> HTTP/1.1
    Content-Type: text/x-lua | application/json

    <data>

These map to `datamanager.method(user, host, store, data)`, where choice
of `method` and its parameters are explained below.

### Verbs

  `GET`    Just fetch data                 `load()` or `list_load()`
  `PUT`    Replace all data in the store   `store()`
  `POST`   Append item to the store        `list_append()`

Note: In a `GET` request, if `load()` returns `nil`, `list_load()` will
be tried instead.
