joemccann / nginx + node setup.md
Created October 25, 2010 02:06
Set up nginx as a reverse proxy to node.js.

The idea is to have nginx installed and node installed. I will extend this gist to include how to install those as well, but at the moment, the following assumes you have nginx 0.7.62 and node 0.2.3 installed on a Linux distro (I used Ubuntu).

In a nutshell,

  1. nginx is used to serve static files (css, js, images, etc.)
  2. node serves all the "dynamic" stuff.

So for example, www.foo.com request comes and your css, js, and images get served thru nginx while everything else (the request for say index.html or "/") gets served through node.

  1. nginx listens on port 80.

Example of (a) successfully executing a cross-domain XHR from the PhantomJS outer context to a wildcard CORS-enabled site; and (b) failing to execute a cross-domain XHR from the PhantomJS outer context to a site that is not CORS-enabled.
var urls = [
/* Wildcard CORS enabled - Works in PhantomJS 1.9.0 */
'http://updates.html5rocks.com',
/* CORS disabled - Fails in PhantomJS 1.9.0 (and every other version) */
'http://www.google.com',
/* Hack workaround? */
/*
function(httpGet, callback) {
phantom.page.settings = (phantom.page.settings || {});
phantom.page.settings.webSecurityEnabled = false;
