HTTP Interaction and Reverse Proxy Lab

Overview

The "HTTP Interaction and Reverse Proxy Lab" provides hands-on experience with HTTP communication, socket programming, and reverse proxy implementation using Python. You’ll learn how to handle HTTP requests, build a simple web server, and implement round-robin load balancing. This approach helps you understand the inner workings of reverse proxies like "Nginx" by exploring their core concepts at a lower level.

Inside this Lab

• Understanding HTTP Interaction: You will learn the basics of HTTP communication, including how clients (browsers) send requests and servers respond, and delve into HTTP methods, headers, and status codes.
• Creating the Simplest Web Server: Gain hands-on experience writing a Python web server using sockets to process HTTP requests and send responses.
• Running a Simple Backend Service: Start backend services using Python's http.server module and validate them.
• Building a Reverse Proxy: Modify your Python web server to act as a reverse proxy, forwarding requests to a simple backend service.
• Setting Up Multiple Backend Services: Deploy multiple backend services with unique responses to simulate a distributed environment.
• Implementing Round-Robin Load Balancing: Extend your reverse proxy to distribute client requests evenly across backend services using round-robin logic.

Learning Outcomes

• Understand the fundamentals of HTTP communication and learn to inspect headers and status codes.
• Write a Python script to create a web server using socket programming.
• Configure multiple backend services and connect them to a reverse proxy.
• Implement round-robin load balancing for efficient request distribution across backend services.
• Gain exposure to foundational concepts used in distributed systems and load balancing.
