Added

• Request timeouts to prevent indefinite hangs when upstream is slow or unresponsive
  • PROXY_TIMEOUT (default 30s): Controls connection, headers, and body timeouts for Ghost requests

Full Changelog: v1.0.0...v1.0.1

v1.0.0

This is the initial release of the Ghost Cache Invalidation Proxy, a tool that sits between a Ghost CMS instance and clients to monitor for cache invalidation headers and trigger configured webhooks.

What's Included

• Proxy functionality for forwarding requests to Ghost CMS
• Detection and parsing of X-Cache-Invalidate headers from Ghost responses (documented here)
• Configurable webhook system to trigger cache purging on any CDN or cache service
• Template support for webhook request bodies with variable substitution
• Docker-based deployment with environment variable configuration

Evolution

This is an evolution of the more specialized ghost-bunnycdn-perma-cache-purger, now abstracted to work with any webhook-capable CDN or cache system. The core functionality remains the same, but with a more versatile and configurable implementation.
