Combining forward and router for node-http-proxy

I'm hosting multiple Node apps on one AWS instance. I've been using apache with virtual hosts but want to only use Node. The node-http-proxy looks like it will do the task but I can't get the forwarding to work with a proxy table.

Here's how proxy table is supposed to work:

var options = {
router: {
    'app1.website.com': 'localhost:7100',
    'app2.website.com': 'localhost:15110'
}
};

var proxyServer = httpProxy.createServer(options).listen(80);

I have app1 and app2 running on the instance and listening to 7100 and 15110 respectively but just using the router option doesn't allow for forwarding.

I can get just one to forward by using:

var options = {
forward: {
    port: 15110,
    host: 'localhost'
}
};

var proxyServer = httpProxy.createServer(15110, 'localhost', options);

Any idea how to get the benefits of both? The documentation says I can pass both 'forward' and 'router' through options but it's not clear how.

Have you tryed 127.0.0.1 instead of localhost? And what did you mean with "doesn't allow fowarding"? What node-http-proxy do is to internally proxy the request, not forward it :)
