It will be much easier for you to use some Node-framework like express, to handle all that routes and requests.

You can install it and body-parser module with these commands:

npm install express --save
npm install body-parser --save

Visit express API References to find out more: http://expressjs.com/4x/api.html

var express = require('express');
var bodyParser = require('body-parser');
var app = express();

app.use(bodyParser.json());

// Handle GET request to '/save'
app.get('/save', function(req, res, next){
  res.send('Some page with the form.');
});

// Handle POST request to '/save'
app.post('/save', function(req, res, next) {
  console.log(req.body);
  res.json({'status' : 'ok'});
});

app.listen(3000);

Inside your app.post() route you can get access to any post data using req.body. So your S_POST["name"] will be req.body.name in this case.
