running node.js http server on multiple ports

Please can anybody help me to find out how to get the server socket context in node.js, so that i will come to know request came on which port number on my server. I can read the server port if i request using http headers but I want it through network and something like socket context which tells request came on which port number.

Here is the sample code:

var http=require('http');
var url = require('url');
var ports = [7006, 7007, 7008, 7009];
var servers = [];
var s;
function reqHandler(req, res) {
        var serPort=req.headers.host.split(":");
        console.log("PORT:"+serPort[1]);//here i get it using http header.
}
ports.forEach(function(port) {
    s = http.createServer(reqHandler);
    s.listen(port);
    servers.push(s);
});

The req object has a reference to the underlying node socket. You can easily get this information as documented at: http://nodejs.org/api/http.html#http_message_socket and http://nodejs.org/api/net.html#net_socket_remoteaddress

Here is your sample code modified to show the local and remote socket address information.

var http=require('http');
var ports = [7006, 7007, 7008, 7009];
var servers = [];
var s;
function reqHandler(req, res) {
    console.log({
        remoteAddress: req.socket.remoteAddress,
        remotePort: req.socket.remotePort,
        localAddress: req.socket.localAddress,
        localPort: req.socket.localPort,
    });
}
ports.forEach(function(port) {
    s = http.createServer(reqHandler);
    s.listen(port);
    servers.push(s);
});
