Rusty TCP Handler

A simple TCP server written in Rust that listens on port 8000, logs incoming requests to a file, and responds with a predefined message.

Features

• Listens for TCP connections on port 8000.
• Logs incoming requests to a file named tcp_handler.log in the received_requests directory.
• Responds to each request with a simple HTTP response containing a custom header.

Requirements

• Rust (latest stable version)
• Cargo (latest stable version)

Installation

1. Clone the repository:

   git clone <repository_url>
   cd rusty_tcp_handler

2. Build the project:

   cargo build

Usage

2. Send requests to the server:

   You can use tools like curl, Postman, or any other HTTP client to send requests to the server.
