HTTP Showcase

This repository contains small, self-contained server implementations that demonstrate key features of HTTP/1.1, HTTP/2, and HTTP/3. The goal is to explore the evolution of the HTTP protocol and showcase how each version improves on its predecessors while maintaining backward compatibility.

Features

HTTP/1.1

• Persistent connections
• Chunked transfer encoding
• Host header handling
• Pipelining (optional)

HTTP/2

• Multiplexed streams
• Header compression (HPACK)
• Stream prioritization
• Server push

HTTP/3

• QUIC-based transport (UDP)
• Improved latency and connection establishment
• Multiplexing without head-of-line blocking

Requirements

• Go (1.18 or later recommended)
• A modern browser or tools like curl/Postman to test server behavior

Getting Started

1. Clone the repository:

   git clone https://github.com/yourusername/http-showcase.git  
   cd http-showcase  

2. Run the server for a specific HTTP version:

   • HTTP/1.1:

     go run ./http1.1/server.go  

   • HTTP/2:

     go run ./http2/server.go  

   • HTTP/3:

     go run ./http3/server.go  

3. Test the server using a browser or tool.
