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

Not all random values are created equal - for security-related code, you need a specific kind of random value.

A summary of this article, if you don't want to read the entire thing:

Don't use Math.random(). There are extremely few cases where Math.random() is the right answer. Don't use it, unless you've read this entire article, and determined that it's necessary for your case.
Don't use crypto.getRandomBytes directly. While it's a CSPRNG, it's easy to bias the result when 'transforming' it, such that the output becomes more predictable.
If you want to generate random tokens or API keys: Use uuid, specifically the uuid.v4() method. Avoid node-uuid - it's not the same package, and doesn't produce reliably secure random values.
If you want to generate random numbers in a range: Use random-number-csprng.

You should seriously consider reading the entire article, though - it's

	HTTP transfer protocols
	=======================

	Git supports two HTTP based transfer protocols. A "dumb" protocol
	which requires only a standard HTTP server on the server end of the
	connection, and a "smart" protocol which requires a Git aware CGI
	(or server module). This document describes both protocols.

	As a design feature smart clients can automatically upgrade "dumb"
	protocol URLs to smart URLs. This permits all users to have the

	apt-get install -y software-properties-common

	For (some of these as per the 12 factor principles)

	1) they are are easy to change between deploys without changing any code

	2) unlike config files, there is little chance of them being checked
	into the code repo accidentally

	3) unlike custom config files, or other config mechanisms such as Java
