I'm working in Node.js Project and I want node to act as a proxy for solr

For proxy: I used Node-http-proxy.
the problem is that proxy work excellent in case of get requests but in case of post requests it results in socket hang up exception

Here is a sample of my node code

var express = require('express');

var router = express.Router();



var http = require('http');

var httpProxy = require('http-proxy')



var proxyOptions = {

  host: 127.0.0.1,

  port: 8983

};

var proxy = httpProxy.createProxyServer(proxyOptions);



// It works excellent in GET request

router.get('/solr/*', function(req, res) {

  proxy.web(req, res, {

    target: 'http://' + proxyOptions.host + ':' + proxyOptions.port

  });

})



// the socket hang up in post request

router.post('/solr/*', function(req, res) {

  console.log('Post Request');

  proxy.web(req, res, {

    target: 'http://' + proxyOptions.host + ':' + proxyOptions.port

  });

})

And this is the error after some time in node console

Error: socket hang up

    at createHangUpError (http.js:1476:15)

    at Socket.socketOnEnd [as onend] (http.js:1572:23)

    at Socket.g (events.js:180:16)

    at Socket.emit (events.js:117:20)

    at _stream_readable.js:943:16

    at process._tickCallback (node.js:419:13)

Any suggestions about the cause of the problem
