Express: Strip out port from

I doubt anyone will ever need this but just in case. I had a scenario where I needed to deliver the hostname (without the port) through an .ejs variable. The hostname comes from the request header so that's easy to find and I simply used a .match with a ternary conditional to keep things clean.

var express = require("express"),
app = express.createServer();

app.get("/", function( req, res ){
  //Strip out port number
  var hostname = ( ) ? 0,":") ) :

  res.render( "index.ejs", {
    layout:   false,
    hostname: "http://" + hostname
