=====

fork of tootallnate's proxy, adding hooks for modifying requests.

$3


This module provides standard "HTTP proxy" logic. You can script your own server
using the proxy server API. Be sure to take a look at the "Examples" section
below.

There is also a companion proxy(1) CLI tool, which spawns an HTTP(s) proxy
server with the specified options.

You could think of proxy(1) as similar to some of the other popular open
source HTTP proxy software:

* [Squid][]
* [Privoxy][]
* [Apache][] with [mod_proxy][mod_proxy]
* More…

Installation
------------

Install with npm:

`` bash
$ npm install proxy
`

If you would like to have the proxy(1) CLI program in your $PATH, then
install "globally":

` bash
$ npm install -g proxy
`


Examples
--------

#### Basic HTTP(s) proxy server

A basic HTTP(s) server with all the default options. All requests are allowed.
CONNECT HTTP method works as well.

` js
var http = require('http');
var setup = require('proxy');

var server = setup(http.createServer());
server.listen(3128, function () {
var port = server.address().port;
console.log('HTTP(s) proxy server listening on port %d', port);
});
`


CLI Tool Examples
-----------------

The proxy(1) CLI tool can be used to spawn HTTP(s) proxy server instances with
various options.

#### Port to bind to

Pass the -p/--port option to with a port number to specify a TCP port to
bind to. Defaults to __3128__ if none is specified.

` bash
$ proxy --port 8080
`

#### Custom Proxy-Authenticate command

Pass the -a/--authenticate switch with a command to execute when the client
Proxy-Authorization header is given. This command determines whether or not the
request is authorized based on the "exit code" of the command.

The relevant request authentication information is passed in as
PROXY_AUTH_USERNAME, PROXY_AUTH_PASSWORD and PROXY_AUTH_SCHEME environment
variables.

For example, to authorize "Basic" authentication with username "foo" and
password "bar":

` bash
$ proxy --authenticate 'if \
[ "$PROXY_AUTH_USERNAME" = "foo" ] && \
[ "$PROXY_AUTH_PASSWORD" = "bar" ]; \
then exit 0; \
fi; \
exit 1;'
``
