Introduction

Welcome to the Key Concepts tutorial! This guide will walk you through the foundational principles of HTTP server development. Whether you're new to networking or looking to deepen your understanding, these concepts are essential for building robust web services. Let's dive in!

Core Principles

Here are the fundamental concepts you need to grasp:

  1. HTTP Methods

    • GET: Retrieve resources
    • POST: Submit data
    • PUT: Update resources
    • DELETE: Remove resources
    • HEAD: Get headers without body
    • OPTIONS: Describe communication options
      ✅ Use the HTTP Methods tutorial for detailed examples.

  2. Status Codes

    • 200 OK: Successful request
    • 404 Not Found: Resource not available
    • 500 Internal Server Error: Server-side issue
    • 301 Moved Permanently: Redirect
      📌 Always check the Status Code guide for debugging tips.

  3. Request/Response Cycle

    • Client sends a request with headers and body
    • Server processes the request and sends a response
    • Responses include status codes and content
      📜 Explore the Request/Response Cycle tutorial for visual breakdowns.

Best Practices

  • Use RESTful design principles for stateless interactions
  • Implement CORS for cross-origin security
  • Prioritize performance optimization techniques
  • Follow security standards like HTTPS and input validation
    🔒 Refer to the Security Best Practices for advanced guidance.
