## What it is
An nginx module that adds the ability to purge content from nginx's FastCGI, proxy, SCGI and uWSGI caches. It exposes configuration directives like proxy_cache_purge to invalidate cached pages, optionally restricted by IP.

## Use cases
- purge cached pages from nginx proxy cache
- invalidate fastcgi cache entries in nginx
- clear uwsgi cache content via HTTP PURGE method
- restrict cache purging to trusted IPs
- expire stale cached responses after content updates

## When to choose
- you run nginx with proxy/fastcgi/scgi/uwsgi caching and need on-demand cache invalidation
- you want a lightweight, production-ready C module compiled into nginx
- you need IP-restricted PURGE method support

## When to avoid
- you use nginx built-in proxy_cache_purge (available in nginx Plus) or a newer nginx with native support
- you need cache purging for non-nginx caches like Varnish or CDN edges
- you want an actively developed module with frequent updates

## Facets
- artifact type: plugin
- maturity: maintenance
- function: caching, http-server, middleware
- domain: web-development, backend, performance, self-hosted
- platform: cross-platform
