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

Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

General rules

Follow standard conventions.
Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
Boy scout rule. Leave the campground cleaner than you found it.
Always find root cause. Always look for the root cause of a problem.

Go - The Ultimate Folder Structure

Organizing your Go (Golang) project's folder structure can help improve code readability, maintainability, and scalability. While there is no one-size-fits-all structure, here's a common folder structure for a Go project:

project-root/
    ├── cmd/
    │   ├── your-app-name/
    │   │   ├── main.go         # Application entry point
    │   │   └── ...             # Other application-specific files

	<?php
	function require_auth() {
	$AUTH_USER = 'admin';
	$AUTH_PASS = 'admin';
	header('Cache-Control: no-cache, must-revalidate, max-age=0');
	$has_supplied_credentials = !(empty($_SERVER['PHP_AUTH_USER']) && empty($_SERVER['PHP_AUTH_PW']));
	$is_not_authenticated = (
	!$has_supplied_credentials \|\|
	$_SERVER['PHP_AUTH_USER'] != $AUTH_USER \|\|
	$_SERVER['PHP_AUTH_PW'] != $AUTH_PASS

	docker run \
	--name {{printf "%q" .Name}} \
	{{- with .HostConfig}}
	{{- if .Privileged}}
	--privileged \
	{{- end}}
	{{- if .AutoRemove}}
	--rm \
	{{- end}}
	{{- if .Runtime}}
