🧱 C HTTP Server

A simple HTTP server built from scratch in C using low-level socket programming.

🚀 Features

• Handles basic HTTP requests
• Supports simple routing:
  • / → Home
  • /sobre → About page
• Returns plain text responses
• Built using POSIX sockets (socket, bind, listen, accept)
• Minimal and easy to understand

🛠️ How to Run

1. Compile

gcc server.c -o server

2. Run

./server

3. Open in browser

http://localhost:8080

📡 Available Routes

Route	Method	Description
/	GET	Home page
/sobre	GET	About page

🧠 How It Works

This server:

1. Creates a socket using TCP
2. Binds it to port 8080
3. Listens for incoming connections
4. Accepts client requests
5. Reads raw HTTP requests
6. Parses routes using simple string matching
7. Sends HTTP responses manually

📌 Example Request

GET / HTTP/1.1
Host: localhost:8080

📌 Example Response

HTTP/1.1 200 OK
Content-Type: text/plain

⚠️ Limitations

• No concurrency (handles one client at a time)
• Basic request parsing (strstr)
• No support for POST/PUT yet
• No file serving
• Not production-ready

---

🎯 Future Improvements

• JSON responses
• Better HTTP parsing
• Support for POST requests
• Multithreading
• Static file serving
• Routing system

📚 Learning Goals

This project was built to understand:

• How HTTP works under the hood
• Socket programming in C
• Client-server communication
• Manual request/response handling
