Scalable vhost middleware for express.


Improves on express.js middleware for vhost by avoiding expensive regex chains. This will perform better and scale more than connect vhost.

If trust proxy is enabled the X-Forwarded-Host header will be respected, so that the hosts can work behind a remote proxy such as Nginx.

var evh = require('express-vhost'),
    express = require('express');
var appFactory = function(echo) {
    var app = express();
    app.get('/', function(req, res) {
    return app;
var server = express();
server.use(evh.vhost(server.enabled('trust proxy')));
evh.register('test1-local', appFactory('test1'));
var app2 = appFactory('test2');
evh.register('test2-local', app2);
evh.register('*.test2-local', appFactory('test2'));
