Caching Proxy

A HTTP caching proxy built with Node.js.

This project acts as a proxy server between a client and an origin server. It forwards incoming requests, caches responses and saves cached responses on subsequent requests to reduce unnecessary network calls.

Features

• Forward HTTP requests to an origin server
• Cache responses using the request method and URL as the cache key
• Return cached responses with X-Cache: HIT
• Return new responses with X-Cache: MISS
• Preserve response status codes and headers
• Persistent file-based cache (cache.json)
• Clear the cache from the command line
