A cool HTTP server in C++ (Winsock)

This is a minimal HTTP server built in C++ using Winsock2.
It supports both GET and POST requests, and logs the client request to the console.

How it works

• HTTP protocol is system-independent.
• What differs is how the OS exposes sockets:
  • Unix/Linux/macOS → use POSIX sockets (file descriptors: int values).
  • Windows → use Winsock, which returns a SOCKET type.

This server:

1. Initializes Winsock (WSAStartup).
2. Creates a TCP socket (socket(AF_INET, SOCK_STREAM, 0)).
3. Binds it to PORT 8080 (or any port you set).
4. Listens for connections (listen).
5. Accepts clients (accept).
6. Reads the request (recv).
7. Responds with:
   • GET → returns "heyo!".
   • POST → echoes the POST body back in the response.

Requirements

• Windows (tested on MSYS2 / MinGW).
• Compiler supporting C++11 or higher.
