This documentation section explains HTTP status codes and authorization mechanisms commonly used in modern web infrastructures.
The Node403 simulation visualizes the HTTP 403 Forbidden response inside a stylized terminal environment. These documentation pages provide additional technical context and explanations.
A comprehensive overview of HTTP status codes used in web communication. HTTP response codes indicate how a server processed a client request and help developers diagnose application and network behaviour.
This reference explains the different HTTP status code classes, including 2xx success responses, 3xx redirects, 4xx client errors, and 5xx server errors, with practical explanations of what each code means and when it appears.
An overview of modern authorization systems used to control access to applications and protected resources. Authorization determines whether a user, service, or process has permission to perform a specific action after authentication.
This guide explains common access control models including RBAC (Role-Based Access Control), ABAC (Attribute-Based Access Control), and modern policy enforcement engines used in web services, APIs, and distributed systems.
The Node403 project is an interactive simulation that demonstrates how authorization layers may deny requests using HTTP status code 403 Forbidden.
These documentation pages explain the technical background behind the concepts visualized in the simulation.
