Forward-Proxy implementation

A simple implementation of a forward proxy for HTTP requests in Go.

Features

• HTTP proxy support
• In-memory caching
• Conditional requests (ETag, Last-Modified)

Quick Start

1. Clone the repository:

git clone https://github.com/aniketpathak028/proxy-go.git
cd proxy-go

2. Run using Podman:

make podman-run

3. Configure your browser or use curl:

curl -x http://localhost:8080 http://example.com

Make Commands

• make podman-build - Build container image
• make podman-run - Run proxy server in container
• make podman-clean - Remove container image

Configuration

Environment variables and their defaults:

• PORT: Default 8080
• CONTAINER_TAG: Default "latest"

Example with custom port:

make podman-run PORT=3000

Limitations

• HTTPS proxying not supported yet (will be added in future)
• In-memory cache only (no persistence)
• Single instance only (no clustering)

Usage

Future Scope

• Add HTTPS support
• Implement persistent caching
• LRU cache eviction policy
