* Feature: Support communication over Unix domain sockets (UDS)

(#20 by @clue)

```php

// new: now supports communication over Unix domain sockets (UDS)

$proxy = new ProxyConnector('http+unix:///tmp/proxy.sock', $connector);

```

* Reduce memory consumption by avoiding circular reference from stream reader

(#18 by @valga)

* Improve documentation

$proxy = new ProxyConnector('user:pass@127.0.0.1:8080', $connector);

Async HTTP proxy connector, use any TCP/IP-based protocol through an HTTP

CONNECT proxy server, built on top of [ReactPHP](https://reactphp.org).

HTTP CONNECT proxy servers (also commonly known as "HTTPS proxy" or "SSL proxy")

are commonly used to tunnel HTTPS traffic through an intermediary ("proxy"), to

conceal the origin address (anonymity) or to circumvent address blocking

(geoblocking). While many (public) HTTP CONNECT proxy servers often limit this

to HTTPS port `443` only, this can technically be used to tunnel any

TCP/IP-based protocol (HTTP, SMTP, IMAP etc.).

This library provides a simple API to create these tunneled connection for you.

Because it implements ReactPHP's standard

[`ConnectorInterface`](https://github.com/reactphp/socket#connectorinterface),

it can simply be used in place of a normal connector.

This makes it fairly simple to add HTTP CONNECT proxy support to pretty much any

existing higher-level protocol implementation.

* **Async execution of connections** -

Send any number of HTTP CONNECT requests in parallel and process their

responses as soon as results come in.

The Promise-based design provides a *sane* interface to working with out of

bound responses and possible connection errors.

* **Standard interfaces** -

Allows easy integration with existing higher-level components by implementing

ReactPHP's standard

[`ConnectorInterface`](https://github.com/reactphp/socket#connectorinterface).

* **Lightweight, SOLID design** -

Provides a thin abstraction that is [*just good enough*](http://en.wikipedia.org/wiki/Principle_of_good_enough)

and does not get in your way.

Builds on top of well-tested components and well-established concepts instead of reinventing the wheel.

* **Good test coverage** -

Comes with an automated tests suite and is regularly tested against actual proxy servers in the wild

This project follows [SemVer](http://semver.org/).

$ composer require clue/http-proxy-react:^1.3

This project aims to run on any platform and thus does not require any PHP

extensions and supports running on legacy PHP 5.3 through current PHP 7+ and

HHVM.

It's *highly recommended to use PHP 7+* for this project.
