HTTP from TCP

A learning project that implements HTTP protocol parsing from scratch using raw TCP sockets in Java.

What's Inside

• TCP Listener — A basic TCP server that accepts connections and reads raw bytes
• HTTP Request Parser — Parses HTTP request lines (method, path, version), headers, and body
• Stream Parser — Reads byte streams and breaks them into lines for processing
• UDP Sender — Simple UDP client for experimentation

Running

# Start the TCP listener
./gradlew runTcp

# Start the UDP sender
./gradlew runUdp

Purpose

Understanding how HTTP works under the hood by building it up from TCP sockets — no high-level HTTP libraries, just raw networking.
