lib-gateway-port 1.2.4

High-performance HTTP gateway and reverse proxy with security features

lib-gateway-port

A lightweight, high-performance HTTP gateway and reverse proxy library for Python applications.

Features

• Path-Based Access Control: Define protected routes with flexible ACL rules
• Request Validation: Built-in validation and sanitization for security
• Connection Pooling: Efficient backend connection management
• Production Ready: Battle-tested in high-traffic production environments
• Zero Dependencies: Pure Python implementation with no external requirements
• Easy Integration: Simple API for quick deployment

Installation

pip install lib-gateway-port

Quick Start

from lib_gateway_port import SecurityGateway

# Initialize gateway
gateway = SecurityGateway(
    backend_host="127.0.0.1",
    backend_port=5000,
    listen_port=9000,
    protected_paths=["/admin/", "/internal/"]
)

# Start the gateway
gateway.start()

Configuration Options

gateway = SecurityGateway(
    backend_host="127.0.0.1",      # Backend server address
    backend_port=5000,              # Backend server port
    listen_port=9000,               # Gateway listening port
    protected_paths=["/admin/"],    # Paths requiring access control
    max_connections=100,            # Maximum concurrent connections
    request_timeout=30              # Request timeout in seconds
)

Use Cases

• API Gateway: Route and protect REST APIs
• Microservices: Central entry point for microservice architectures
• Legacy Applications: Add security layer to existing applications
• Access Control: Implement path-based authentication requirements
• Load Distribution: Balance traffic across backend servers

Architecture

Client Request → Gateway (ACL + Validation) → Backend Application
                        ↓
                  Protected Paths
                  Request Sanitization
                  Connection Pooling

Security

This library implements industry-standard security practices:

• Request validation and sanitization
• Path normalization to prevent traversal attacks
• Connection timeout management
• Access control list enforcement

Performance

Optimized for high-throughput production environments:

• Persistent backend connections for reduced latency
• Efficient request parsing and routing
• Minimal memory footprint
• Suitable for handling thousands of requests per second
