direct ajax GET requests somewhere other than the localhost main directory?

I'm trying to have to have an ajax call from my home page, but it's already rerouted to index.html. So here's what I'm doing. This is my ajax call...var xhr = new XMLHttpRequest(); xhr.open('GET', "http://localhost:4000" + "?fetching=true", true); xhr.onload = function(){ if(this.status==200){ //stuff } } xhr.send(); and then on the server side (app.js) I separate GET requests with the fetching query and the ones without...app.get('/', function(req, res){ if (req.query.fetching){ //do stuff } else { res.sendFile(__dirname + '/index.html'); } }); Is this good practice? Is it the standard way of doing this? And is there so I can direct ajax GET request somewhere other than app.js. I've tried http://localhost:4000/submit but it never works unless it directs to the main localhost path (app.js)
