Description:

Hello, following a simple and straight forward tutorial. Everything works fine, but I was just curious as to why I'm getting a double request received when I refresh/access my page?

Part of my code:

function onRequest(request, response){ console.log('request received'); response.writeHead(200, {"Content-Type": "text/plain"}); response.write('Hello world baby'); response.end(); } //creating server http.createServer(onRequest).listen(8888); console.log("server has started");

    I bet it's because you're sending two requests. Commented Mar 4, 2015 at 16:03

    Probably, your browser is trying to load /favicon.ico from your server. Commented Mar 4, 2015 at 16:04

    Use your browser developer console to see actual HTTP requests. Commented Mar 4, 2015 at 16:04

    Debug each request with console.log('request received:', request, response); Commented Mar 4, 2015 at 16:06

    @gmo it'll be a lot of useless data, something like console.log('request received:', request.url); will be much more useful. Commented Mar 4, 2015 at 16:07

Your browser is looking for the favicon.ico, then it sends a request for the actual content. Try to console.log both the request and response to get more information.
