Express res.redirect() behaving very strangely

Question

I'm using a customized version of the vhost connect/express middleware and inside it I check for the www subdomain. If I find that subdomain, then I redirect to the host + path without the www. So for example, if I go to www.google.com I want to redirect to google.com. I call:

if (subdomain === "www") {
  res.redirect(req.headers.host.split('.').slice(1).join('.') + req.url);
}

However, this redirects me to: www.google.comgoogle.com as it appends the new url to the original one. Why is it doing this?

What do you see if you `console.log()` both `req.headers.host` and `req.url`? — ebohlman, Jul 03 '12 at 22:54

Try prepending the protocol:

res.redirect('http://' + req.headers.host.split('.').slice(1).join('.') + req.url);
