HTTP/HTTPS proxy plugin of connect/express for XHR(XMLHTTPRequest) with referer restriction and appending Access-Control-Allow-Origin for cross domain XHR2 Based on cdproxy by macchadogj(thanks)

Installation

$ npm install xhr2proxy

Usage

basic

var xhr2proxy = require('xhr2proxy');

	.use(xhr2proxy({prefix:'myprefix'})) //proxy by default.
	.use(function ( req, res ) {
	res.end("Hello from Connect!");
}).listen(8000);

//var xhr=new XMLHttpRequest();
//xhr.open('get','http://localhost:8000/myprefix/http://myremote.server',false);
//xhr.send();

basic(express)

var xhr2proxy = require('xhr2proxy');
var app=require('express').createServer();
app.use(xhr2proxy());
app.listen(8000);

//var xhr=new XMLHttpRequest();
//xhr.open('get','http://localhost:8000/prefix/http://myremote.server',false);
//xhr.send();

Appending Access-Control-Allow-Origin to response headers

It allows XMLHttpRequest level2 to connect with non supported servers from outside of the domains which runs this script.

var xhr2proxy = require('xhr2proxy');

connect()
	.use(xhr2proxy({prefix:'myprefix',acao:'*'}) //Append [Access-Control-Allow-Origin: *]
	.use(function ( req, res ) {
	res.end("Hello from Connect!");
}).listen(8000);

//var xhr=new XMLHttpRequest();
//xhr.open('get','http://anywhrere:8000/myprefix/http://myremote.server',false);
//xhr.send();

referer restriction

prevent out-site using by referer restriction.CAUTION:It cannot recognize fake headers.

var xhr2proxy = require('xhr2proxy');

connect()
	.use(xhr2proxy({prefix:'myprefix',referer:/^http:\/\/localhost/})) //deny if referer isnot http://localhost...
	.use(function ( req, res ) {
	res.end("Hello from Connect!");
}).listen(8000);

//var xhr=new XMLHttpRequest();
//xhr.open(''get',http://localhost:8000/myprefix/http://myremote.server',false);
//xhr.send();
//with referer http://localhost:8000/anywhere.html
