Listening to both GET and POST, node.js server

Here's a basic http sever that I've built using this tutorial. I'll only show one function here that creates the server:

function Server(resourceMap, rootFolder) {

    this.resourceMap = resourceMap;
    this.rootFolder = rootFolder;

    function connectionHandler(socket) {
        var data = "";
        console.log('server connected');
        console.log('CONNECTED: ' + socket.remoteAddress +':'+ socket.remotePort);
        socket.setEncoding('utf8');
            socket.on('data',function(newData) {
                           console.log("NEW DATA\n" +    newData); data += newData;
                            });
        socket.on('end',function(data) {
                           console.log("DATA\n" + data);                                   router.route(data,socket,handle,resourceMap,rootFolder);
                            });
    }

    this.server = net.createServer(connectionHandler);

    this.port = undefined;

    this.startServer = function(port) {
        this.port = port;
        this.server.listen(port, function() { 
            console.log('server bound');});
    }
}

So as you can see, I have two listeners - data and end. When data is emitted I add what was sent to a variable, and when end is emitted I send this variable to another function. This doesn't work with GET request - all the data is sent at once and end is not emitted.

I have to be able to handle both methods. Also, this is a homework assignment which is why I can't use the http module.

Any suggestions? Thanks!

P.s. as I am new to node.js and JavaScript any general comments will be welcomed
