summary: HTTP Authentication using custom JSON protocol

...

Introduction

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

To authenticate users, this module does a `POST` request to a configured

URL with a JSON payload. It is not async so requests block the server

until answered.

Configuration

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

``` lua

VirtualHost "example.com"

authentication = "custom_http"

auth_custom_http = "http://api.example.com/auth"

```

Protocol

========

The JSON payload consists of an object with `username` and `password`

members:

    {"username":"john","password":"secr1t"}

The module expects the response body to be exactly `true` if the

username and password are correct.
