var http = require('http');
var url = require('url');
var QS = require('querystring');

var siteUrl = url.parse('http://posttestserver.com/post.php');
var param = { 'q': 'value1', 'param2': 'value2' };
param = QS.stringify(param);

var headers = {
    'Host': siteUrl.host,
    'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_1) AppleWebKit/535.2 (KHTML, like Gecko) Chrome/15.0.874.121 Safari/535.2',

    //'Cookie': 'key=value',

var site = http.createClient(siteUrl.port || 80, siteUrl.host);

var request = site.request("POST", siteUrl.pathname, headers);
request.write(param);
request.end();

request.on('response', function(response) {
        response.setEncoding('utf8');
        console.log('Status: ' + response.statusCode);
        response.on('data', function(data) {
                console.log("Received Data: " + data);
        });
