Question

I need to use Node.JS for 3 domains. How can I do it? At the moment I have one application that binds port 80, how to support more than one domains?
I also use cluster module that forks my application in 3 processes.

Probably best way, use connect vhost, which is a connect module.

Or: you can rewrite your URLs with a global URL handler, and then write your constraints based on the rewritten URL:

app.get('*', function(req, res, next){ 
  if(req.headers.host === 'domain1.com')
    req.url = '/domain1' + req.url;
  else if(req.headers.host === 'domain2.com')
    req.url = '/domain2' + req.url;
  next(); 
})

.get('/domain1/index', function(){ 

}) 

.get('/domain2/index', function(){ 

});
