Simple Page Cache is an extremely simple, super-fast page cache for WordPress. The plugin stores full HTML pages on disk for non-logged-in visitors. The cache is automatically cleared when content is updated, ensuring visitors always see fresh content. Ideal for small to medium-sized sites and webshops that want maximum speed without complex settings.
Main features: 
– Caching for non-logged-in users (GET requests only) 
– Path-based cache structure for nginx direct serving (<code>/host/path/index.html</code>) 
– Cache files are stored in <code>/wp-content/uploads/simple-page-cache/</code> 
– Drop-in (<code>advanced-cache.php</code>) for maximum speed before WordPress loads 
– Nginx configuration generation for direct cache serving 
– Automatic cache clearing when posts/pages are updated 
– E-commerce integration with intelligent cache clearing for: 
 – WooCommerce (orders, stock updates, product changes) 
 – Easy Digital Downloads (purchases, download updates) 
 – BigCommerce for WordPress (product updates) 
 – Generic e-commerce plugins (product post types) 
– Automatic detection of dynamic pages (cart, checkout, account, wishlist) for: 
 – WooCommerce 
 – BigCommerce for WordPress 
 – Easy Digital Downloads 
 – iThemes Exchange 
 – Jigoshop 
 – WP-Shop 
– Detected dynamic pages are automatically excluded from caching 
– Manual cache clearing via admin bar button 
– Nginx config regeneration via admin bar button 
– Performance comments in cached HTML files 
– No complex settings, no database writes
<h3>Nginx Configuration</h3>
For maximum performance, you can configure nginx to serve cached files directly without PHP processing:
<ol>
<li>Copy the nginx configuration from <code>/wp-content/uploads/simple-page-cache/nginx.conf</code></li>
<li>Add the configuration to your nginx server block for your domain</li>
<li>Test nginx configuration: <code>sudo nginx -t</code></li>
<li>Reload nginx: <code>sudo systemctl reload nginx</code></li>
</ol>
The nginx configuration includes: 
– Internal location block for serving cached files 
– Automatic cache bypass for logged-in users 
– Automatic cache bypass for requests with query strings 
– Debug headers to identify cache hits
Benefits of nginx direct serving: 
– Faster response times (no PHP processing) 
– Lower server load 
– Better scalability 
– Direct file serving from disk
<h3>How it works</h3>
<ul>
<li>For every non-logged-in visitor and every GET request, a static HTML file is created and served.</li>
<li>Path-based cache structure: Cache files are organized as <code>/host/path/index.html</code> for direct nginx serving.</li>
<li>Pages with characteristics of dynamic e-commerce pages (such as cart, checkout, account, wishlist) are automatically detected and excluded from caching. The plugin recognizes WooCommerce, BigCommerce, Easy Digital Downloads, iThemes Exchange, Jigoshop, and WP-Shop.</li>
<li>The list of excluded pages is automatically maintained in a file in the cache directory.</li>
<li>Automatic cache clearing: When posts or pages are updated, the plugin efficiently clears cache using the new path-based structure and scans for related content.</li>
<li>E-commerce integration: For WooCommerce, when orders are placed or product stock is updated, the plugin automatically clears cache for the affected products and related pages (categories, tags, shop pages, homepage).</li>
<li>Performance comments: Each cached HTML file includes a comment with timestamp and host information for debugging and transparency.</li>
<li>Nginx integration: Generated nginx configuration allows direct serving of cached files without PHP processing for maximum performance.</li>
</ul>
<h3>Clearing the cache</h3>
<ul>
<li>Click the “Clear Page Cache” button in the admin bar (visible to administrators only) to remove all cache files.</li>
<li>Click the “Regenerate nginx.conf” button in the admin bar to regenerate the nginx configuration file.</li>
</ul>
<h3>Deactivation</h3>
<ul>
<li>When deactivating the plugin:
<ul>
<li>The drop-in <code>advanced-cache.php</code> is removed.</li>
<li>The <code>define('WP_CACHE', true);</code> line (if placed by this plugin) is removed from <code>wp-config.php</code>.</li>
</ul>
</li>
</ul>
