Virtual Hosts on nginx (CSC309)

When hosting our web applications, we often have one public IP address (i.e., an IP address visible to the outside world) using which we want to host multiple web apps. For example, one may wants to host three different web apps respectively for example1.com, example2.com, and example1.com/images on the same machine using a single IP address.

How can we do that? Well, the good news is Internet browsers

Prerequisites : the letsencrypt CLI tool

This method allows your to generate and renew your Lets Encrypt certificates with 1 command. This is easily automatable to renew each 60 days, as advised.

You need nginx to answer on port 80 on all the domains you want a certificate for. Then you need to serve the challenge used by letsencrypt on /.well-known/acme-challenge. Then we invoke the letsencrypt command, telling the tool to write the challenge files in the directory we used as a root in the nginx configuration.

I redirect all HTTP requests on HTTPS, so my nginx config looks like :

server {

	Secure sessions are easy, but it's not very well documented, so I'm changing that.
	Here's a recipe for secure sessions in Node.js when NginX is used as an SSL proxy:

	The desired configuration for using NginX as an SSL proxy is to offload SSL processing
	and to put a hardened web server in front of your Node.js application, like:

	[NODE.JS APP] <- HTTP -> [NginX] <- HTTPS -> [CLIENT]

	To do this, here's what you need to do:

	/**
	* @variables
	*/
	var thisName = prompt('Restaurante: Ingrese su nombre');
	var thisCupon = "Aplicando Cupón...";

	var thisEatMenu = ['Arroz', 'Pollo', 'Vegetales', 'Salsa'];
