Ok, so it seems pretty easy in Node.js to get the hostname of the request being made to my server:

app.get('/', function(req,res){
    console.log(req.headers.host);
});

Is there an easy way to determine the hostname of my actual http server? For example, my server is running at the address http://localhost:3000 - can I programatically determine this address? I am using expressjs.

http node.js express
