🧠 Chapter 1: The Birth of HTTP (a.k.a “The Simpler Times”)

Long ago, in the early 90s, the web was like a sleepy village — just text, one request at a time.

HTTP/0.9 was born as a tiny, one-line protocol — client says “Hey, give me that HTML file!” and server goes “Sure, here you go.”

• One request = one TCP connection 🧵
• Only supported GET method 🗂️
• No headers, no status codes, no metadata — just raw HTML output.

It was fast for that era, but soon… the web got greedy 😅

People wanted images, CSS, scripts, APIs — and suddenly HTTP/0.9 looked like a flip phone in a smartphone world.

⚙️ Chapter 2: HTTP/1.0 — “We Need More Features!”

As websites grew, HTTP/1.0 arrived (mid-90s).

It introduced the basic HTTP semantics we still use today — methods like GET, POST, HEAD, and status codes (200, 404, etc).

🧩 Key additions:

• Headers (Content-Type, Content-Length, etc)
• Versioning (HTTP/1.0)
• MIME types for different content
• Response metadata and caching hints

But one huge problem remained 👇
