Overview

This project implements a basic HTTP/1.1 server from scratch using raw TCP sockets in Java. The goal is to understand networking, HTTP semantics, and server architecture without using frameworks.

Project Progress Log

Day 1

• Implemented a minimal TCP server in Java using ServerSocket.
• The server listens on port 8080, accepts a single client, and reads raw bytes from the input stream.
• Verified behavior using curl to inspect the raw HTTP request sent by the client.
• No response is returned to the client yet (connection remains open until client closes).
• Objective: observe HTTP over raw TCP without frameworks.

Day 2

• Refactored the socket reading logic into a separate ClientHandler class to improve structure.
• Main now only starts the server, accepts the client, and delegates the work.
• No change in functionality: server still prints raw HTTP request data and closes resources afterwards.
• Refactor prepares the codebase for future steps including concurrency and basic HTTP parsing.

Day 3 — HTTP Request Parsing

Implemented the first stage of HTTP protocol handling:

• Parsed request line (method, path, version) from raw TCP input.
• Parsed headers into a Map<String, String>.
• Added HttpRequest class for structured representation.

Tested using curl and browser; server correctly prints parsed request fields.

Next: routing + HTTP responses.
