GO-Web-Cache

GO-Web-Cache is a simple caching server written in Go that acts as a reverse proxy to cache responses from a backend server. It includes features such as caching based on Cache-Control directives, health checks, metrics, and an admin API to manage cached items.

Project Structure

The project is organized into the following packages:

• pkg/logging: Contains logging utilities for request and general logging.
• pkg/cache: Provides in-memory caching functionality and utilities.
• pkg/metrics: Handles Prometheus metrics collection and server.
• pkg/config: Loads and manages configuration settings.
• pkg/proxy: Implements the reverse proxy functionality with caching logic.
• pkg/admin: Includes handlers for the admin API endpoints.
• pkg/health: Implements health check and version information handlers.
• pkg/security: Contains security checks, such as WordPress login cookie detection.
• main.go: Main entry point for starting the caching server.

Usage

To start the GO-Web-Cache server, run the following command:

go run main.go

This will start the caching server based on the configurations provided in config.json or through environment variables.
