node.js HTTP request parsing (using net module)

Question

Writing an HTTP simple server on top of Net node.js module, not using HTTP module.

I have a server listening at localhost:port with a socket opened.

socket.on('data', function(data){
    clientMsg += data;
});

Once I type the address in the browser I can see the GET request is in clientMsg.

In order to return a response I use:

 socket.on('close', function(){ something response generating here});

But this is not working well as it sends the response only once I click ESC or STOP in the browser.

So the question is, how can I know the browser finished sending the message and waits for a response, without closing the connection?

You would use the event connection instead of close. Event: 'connection'

Also, this is the structure that is documented for such a server:

var net = require('net');
var server = net.createServer(function(c) { //'connection' listener
    console.log('server connected');
    c.on('end', function() {
        console.log('server disconnected');
    });
    c.write('hello\r\n');
    c.pipe(c);
});
server.listen(8124, function() { //'listening' listener
    console.log('server bound');
});

Thanks for the reply, I saw that as well and couldn't understand, the c.pipe part, does it sends the input after the other side finished to stream the data ? Moreover, when I connect to 127.0.0.1:8124 in Firefox, it does show the HTTP request, but it seems firefox still tries to retrieve data

c.write('hello\r\n'); Sends hello trough the socket. Pipe is a bit different nodejs.org/docs/v0.6.6/api/all.html#stream.pipe

Ok, I am testing the pipe method, I will accept once I fully understand that is the answer, thanks.
