Answer 1

In your nodejs server program you can check for request method and action.

if((request.method == 'POST') && (request.url == '/file-upload') {
  .......
}

Updated -

var http = require("http");
var url = require("url");
var fs = require("fs");

http.createServer(function(req, res) {
  switch (url.parse(req.url).pathname)
  { 
    case '/': 
      console.log('server side methodcalled'); 
        fs.readFile(__dirname + '/index.html',
          function (err, data) {    
            res.writeHead(200);
            res.end(data);
          });
        break;
    case '/file-upload': 
      console.log('server side method called');
      break; 
    default: 
      console.log('server side method called');
      break;
  }
}).listen(3000);

Now you can connect to localhost:3000

In order to implement file uploading, you'll need to read the body of the request and parse out the various multiple parts. This can be tricky, so I'd strongly suggest you use an existing module like formidable, or something that invokes it behind the scenes like connect.bodyParser() or express.bodyParser().
