Caching Proxy Server

Overview

This project is a caching proxy server built using Go and Redis. It forwards requests to an origin server, caches responses for faster retrieval.

Features

• Forward Proxy: Forwards client requests to an origin server.
• Response Caching: Uses Redis to store responses for a specified time.
• Cache HIT/MISS: Displays whether the response was served from cache or the origin server.

Tech Stack

• Go (Golang)
• Redis (for caching)

Requirements

• Go (>=1.21)
• Docker (to run Redis in a Docker container)

Installation

1. Clone the repository:

   git clone https://github.com/<user_name>/proxy_server.git
   cd proxy_server

2. Install the dependencies:

   go mod tidy

3. Run the redis docker compose file:

   docker compose -f redis_docker_compose.yml up -d

4. Start the proxy server:

   go run server.go --port 3000 --origin http://dummyjson.com

   You can change the port no. and the orgin server url.

Usage

Send a test request:

curl -v http://localhost:3000/some_path

• If the response is cached, you'll see Cache HIT.
• If the response is fetched from the origin, you'll see Cache MISS.
