Simple HTTP Server

A lightweight, custom-built HTTP server implemented completely from scratch in Java. This project demonstrates the core mechanics of web servers by utilizing raw TCP sockets, custom message parsing, and multi-threading, all without relying on heavyweight external web frameworks.

Features

• Pure Java Implementation: Built using standard Java networking libraries and core socket programming techniques.
• Multithreaded Architecture: Efficiently handles multiple concurrent client connections by dispatching requests to dedicated worker threads.
• Custom HTTP Parser: Reads and decodes incoming raw HTTP streams, accurately extracting HTTP methods, targets, versions, headers, and body content.
• Protocol Adherence: Generates structurally valid HTTP responses complete with appropriate status codes (e.g., 200 OK, 404 Not Found, 500 Server Error).
• Static File Serving: Automatically resolves, reads, and serves static web assets (HTML, CSS, text) from a designated web root directory.
• Dynamic Configuration: Centralized server setup using JSON configuration files to easily manage ports and web root paths.
• Modular Design: Clean separation of concerns between server initialization, connection management, request handling, and file system operations.

Tech Stack

• Language: Java
• Build Tool: Maven
• Configuration Parsing: Jackson (JSON)
• Networking: Java java.net.Socket and java.net.ServerSocket
