HTTP Protocol Explained: Differences between 0.9, 1.0, and 1.1
Struggling to understand why your microservices are slow? The secret often lies in the TCP handshake overhead and connection management—concepts that evolved directly from the history of HTTP.

The Summary:
In this video, we strip away the frameworks and look at the raw evolution of the HTTP protocol. We travel from Tim Berners-Lee's 1991 "one-line" prototype (HTTP 0.9) to the metadata revolution of 1.0, and finally, the performance-driven persistence of HTTP 1.1. We explore not just the history, but the engineering trade-offs, Golang implementation details, and the system design principles that govern how the web works today.
What You Will Learn:
The "One-Line" Era (HTTP 0.9): How the web started with zero headers and instant connection drops.
The Metadata Revolution (HTTP 1.0): The introduction of Status Codes, Headers, and Content-Types.
The Performance Killer: Understanding the cost of the TCP Three-Way Handshake and why HTTP 1.0 was inefficient.
HTTP 1.1 & Persistence: How Keep-Alive works to solve latency issues.
Senior Engineering Concepts: Deep dives into Head-of-Line Blocking, Idempotency, and Connection Pooling.
Golang Examples: Real-world code snippets simulating raw TCP connections for each protocol version.
Target Audience:
Backend Software Engineers, DevOps professionals, and developers preparing for System Design interviews who want to understand the "why" behind web performance.
