Fix a error for the use of the http-proxy and the body parser for express. Without the "connect-restreamer" the post request is not piped correct to the proxy. Add the "connect-restreamer" as middleware behind the body parser fix the issue.

app.js

var express = require('express');
var bodyParser = require('body-parser');
var httpProxy = require('http-proxy');

var app = express();

/* create a proxy server */
var proxy = httpProxy.createProxyServer({});

/* proxy the hole /example path */
app.all('/example*', function(req, res) {
  "use strict";
  proxy.web(req, res, { target: 'http://example.com:8080' });
});

// ... other middlewars
app.use(bodyParser.json());

// .. other middlewars

/**
 * add for a issue with body parser and proxy server to put 
 * the post request correct to the proxy
 */
app.use(require('connect-restreamer')());


module.exports = app;
