ExpressJS Server - How to handle multiple domains

Question

I'm fooling around a little with Express and I'm wondering, what the "most correct" way is to handle multiple domains which are linked to the same server. Lets assume we have - foo.com - bar.net - baz.com which all point to `111.222.333.444`. That machine is running NodeJS with Express. My current solution looks like this: ``` var express = require( 'express' ), app = module.exports = express.createServer(), // ... more lines ... app.get( '/', routes.index.bind( app ) ); ``` Thus far this is pretty straightforward. The only exception so far is in my `app.configure` call, where I didn't make a call to `.use( express.static() )`. Thats because the `.routes.index()` method looks like so right now: ``` var fs = require( 'fs' ), // ... more lines ... exports.index = function( req, res ) { var host = /(\w+\.)?(.*)\.\w+/.exec( req.header( 'host' ) ), app = this; switch( host[ 2 ] ) { case 'foo': app.use( express.static( '/var/www/foo' ) ); fs.readFile( '/var/www/foo/index.html', 'utf8', file…

I like to use bouncy as a front end reverse-proxy - this lets you run totally different express stacks as different server processes (each with different features and separated for robustness)...

You can then decide how to route to different ports, it works fine with WebSockets.

```
var bouncy = require('bouncy');

bouncy(function (req, bounce) {
    if (req.headers.host === 'bouncy.example.com') {
        bounce(8000);
    }
    else if (req.headers.host === 'trampoline.example.com') {
        bounce(8001)
    }
}).listen(80);
```
