BrenWP Cache speeds up WordPress by serving cached HTML pages to anonymous visitors. On a cache miss, WordPress renders the page normally; BrenWP Cache captures the final HTML output and stores it as a file. On subsequent requests, the cached HTML is served early, reducing server load and improving response times.
This plugin is intentionally minimal, transparent, and WordPress.org-friendly: 
* No telemetry, no tracking, no “phone home” 
* No external services or dependencies 
* Admin UI assets are strictly scoped to this plugin’s pages
<h3>Key features</h3>
Full-page file cache for anonymous visitors 
* Caches full HTML documents for GET requests only. 
* Designed for the common “public pages” scenario where most traffic is anonymous. 
* Avoids caching in common non-cacheable contexts such as admin, AJAX, REST, feeds, previews, searches, and similar endpoints.
Rules to prevent caching personalized or dynamic content 
* Exclude logged-in users (recommended; enabled by default). 
* Exclude URLs (one per line): 
 – Prefix rules (e.g. <code>/checkout</code>) 
 – Wildcards (e.g. <code>/cart*</code>) 
* Exclude by cookies (useful for ecommerce/session cookies). 
* Exclude by user agent (bots, scanners, special clients). 
* Bypass query parameter: when present (e.g. <code>?nocache=1</code>) caching is bypassed for that request. 
* Optional 404 caching (disabled by default; enable only if your 404 output is safe and static).
Tools and automation 
* One-click Purge cache tool in WP Admin. 
* Optional auto-purge when posts are updated (useful for content sites that publish/edit frequently).
Security and WordPress.org compliance 
BrenWP Cache is built to meet WordPress.org review expectations: 
* Capability checks + nonces for state-changing admin actions 
* Strict sanitization/validation of input and late escaping for output 
* Cache directory is constrained under <code>wp-content/cache/brenwp-cache</code> with path safety guards 
* Cached HTML is served as a full document (not escaped) and is integrity-verified with an HMAC signature; unsigned/invalid cache is treated as a miss 
* No obfuscation, no remote calls, no dangerous execution patterns
<h3>Recommended usage (important)</h3>
A full-page cache should never store private/personalized output. For best results: 
* Keep “Exclude logged-in users” enabled. 
* Add exclusions for dynamic endpoints such as: 
 – <code>/checkout</code>, <code>/cart</code>, <code>/my-account</code> (WooCommerce) 
 – Any pages that show user-specific data, pricing, currency switching, or session-based content 
* If a page sets cookies or sends <code>Cache-Control: private/no-store/no-cache</code>, it will not be cached.

<h3>Privacy</h3>
Holographic Extreme Cache does not collect analytics, does not track visitors and does not send site data to a third-party service.
The plugin stores cache files, configuration helper files, generated WebP image files and optional log files inside the WordPress uploads directory. Logging is off by default.
<h3>Uninstall</h3>
The plugin can remove its settings, cache files, configuration files, log files and scheduled events on uninstall if the uninstall cleanup option is enabled before uninstalling.
If uninstall cleanup is not enabled, settings and generated files are left in place so the site owner can remove or inspect them manually.
Generated WebP image files are not automatically removed unless the plugin uninstall cleanup process specifically handles them. This helps avoid removing media files that may still be referenced by the site.
