Node.js www - non www redirection

Question

Is there a chance to somehow redirect www to non-www URLs in node.js? Since there is no htaccess in node web server I am curious how to do that.

This is a basic exemple of how you could mimic the behavior of the redirect directive of apache in nodejs.

The function redirect takes either a RegExp or a string.

var http, redirect;
http = require("http");
redirect = function(host, res, pattern, redirect){
    if (host == pattern || (pattern instanceof RegExp && host.match(pattern))) {
        console.log("Redirected " + host);
        res.writeHead(302, {
        'location': redirect
    });
    res.end();
}};

http.createServer(function(req, res){
    redirect(req.headers.host, res, /^www/, 'http://plouf.url');
    redirect(req.headers.host, res, 'www.plouf.url', 'http://plouf.url');
    res.writeHead(200, {
        'Content-Type': 'text/plain'
    });
    res.end('Hello World\n');
}).listen(8000, '127.0.0.1');
