Scraps

Graveyard of old code:

// main proxy logic
httpProxy.createServer(function (req, res, proxy) {
	//
	// Proxy both HTTP & HTTPS requests
	//
	
	//
	// Put your custom server logic here
	//
	// Example: 
	// A simple round-robin load balancing strategy.
	// 
	// if (ips instanceof Array) {
	// var target = loadBalance(ips);
	// proxy.proxyRequest(req, res,  target);
	// 
	//} else {	
	//}
	// 
	// check if this is an express server
	var domains = config.hosts.express;
	var routes = config.routes;
	var host = req.headers.host || false;
	var protocol = req.socket.encrypted ? 'https' : 'http';
	// #4 - Always redirect a www request 
	if (/^www/.test(host)){ 
		// remove www prefix
		host = host.replace(/^www\./, '');
		// 
		res.writeHead(301,
			{Location: protocol+ '://'+host + req.url });
		res.end();
	}
	
	//#14 FIX: removing port from host
	if(host.indexOf(":") > -1) host = host.substring(0, host.indexOf(":") );
	// get the 'naked' domain
	var domain = host;
	if (/^dev/.test(domain)){ 
		// include www here?
		domain = domain.replace(/^dev\./, '');
	}
	// #17 - check direct routes
	// pick the port 
	var port = ((domains.indexOf(domain) > -1) ? config.ports.express : config.ports.router) || false;
	// don't continue if there is no host/port
  	if( !host || !port ) return;
  
	proxy.proxyRequest(req, res, {
		host: host,
		port: port
	});
	
}).listen(config.ports.proxy);
