Simple reverse proxy of Facebook API

proxy.js

var http = require('http'),
    https = require('https'),
    httpProxy = require('http-proxy');

httpProxy.createServer(function (req, res, proxy) {
    console.log("Received request.");
    proxy.proxyRequest(req, res, {
        host: 'graph.facebook.com',
        port: '443',
        https: true
    }); 
    console.log(proxy);
}).listen(8000);

Does this allow one to use facebook as a proxy server or what does it exactly do?
