globalip.js

var http = require('http');

var data = '<?xml version="1.0"?>' +
	'<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" s:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">' +

		'</s:Body>' +
	'</s:Envelope>';

var options = {
	host   : '192.168.0.1',

	method : 'POST',
	headers: {

};

var req = http.request(options, function(res) {
	console.log('STATUS: ' + res.statusCode);
	console.log('HEADERS: ' + JSON.stringify(res.headers));

		console.log('BODY: ' + chunk);
	});
});

req.on('error', function(e) {
	console.log('problem with request: ' + e.message);
});

// write data to request body
req.write(data);
req.end();
