Proxy HTTP/HTTPS Server

📌 Overview

A proxy server supporting HTTP/HTTPS protocols, built with Python. Features include caching, dynamic site blocking, real-time statistics, comprehensive logging, and a menu-driven management interface.

🚀 Features

• Caching Mechanism: Speeds up browsing by storing frequently accessed content.
• Dynamic Site Blocking: Block access to specific sites in real-time.
• Real-time Statistics: Monitor requests, cache hits, and blocked sites.
• Logging System: Tracks access logs, errors, and security events.
• Centralized Management Interface: Easily configure, monitor, and control the proxy.
• Graceful Shutdown & Data Persistence: Saves logs, cache, and settings before exiting.

🛠️ Technologies Used

• Python
• Flask
• Socket Programming
• Threading
• Logging
• SQLite
• HTTP/HTTPS Protocols

🔧 Installation

Prerequisites

Ensure you have Python 3.x installed on your system.

Steps to Install

# Clone the repository
git clone https://github.com/your-username/proxy-http-https-server.git
cd proxy-http-https-server

# Install dependencies
pip install -r requirements.txt

# Run the proxy server
python proxy_server.py

🚀 Usage

1. Start the Proxy Server

   python proxy.py

2. Configure Your Browser or System to Use the Proxy
   • HTTP Proxy: http://localhost:8080
   • HTTPS Proxy: http://localhost:8080
3. Manage the Proxy Using the Interface
   • View logs & statistics
   • Modify blocklists
   • Stop the server gracefully

🚧 Challenges Faced

• Handling HTTPS Traffic: Implemented SSL/TLS certificate handling for secure tunneling.
• Efficient Caching: Used hash-based storage with expiration policies.
• Real-time Blocklist Updates: Used thread-safe data structures for smooth updates.
• Graceful Shutdown: Implemented signal handling to save data before exiting.

Logs & Cache Management

• Logs are stored in the logs/ directory.
• Cached responses are stored in cache/.
• Run proxy.py with appropriate flags for additional functionalities.
