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>
BrenWP Cache does not collect personal data and does not send telemetry. Optional Preload requests only your own site URLs. 
Caching is file-based on your server, stored under your WordPress content directory, and controlled by your configuration.

Purgely manages caching behavior for WordPress sites using Fastly as an edge caching solution. The plugin exposes useful 
APIs to help control how pages on your site are cached, as well as provides sane defaults to make this a plug and play 
solution for Fastly cache management.
The plugin handles the following:
<ul>
<li>Sets the <code>Surrogate-Control</code> header to control the expiration time for pages</li>
<li>Sets the <code>stale-while-revalidate</code> and <code>stale-if-error</code> <code>Cache-Control</code> directives for managing these special Fastly 
behaviors</li>
<li>Set groups of <code>Surrogate-Keys</code> for all pages to provide purging across multiple pages with one command</li>
<li>Provides invalidation of posts and related posts on save</li>
</ul>
Each of these items have sane defaults with ways to override them and configure them to your liking.
Additionally, the plugin exposes a WP CLI command to provide more flexible purging options.
