<p><strong>Simple Page Cache</strong> 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.</p>
<p><strong>Main features:</strong><br />
– Caching for non-logged-in users (GET requests only)<br />
– <strong>Path-based cache structure</strong> for nginx direct serving (<code>/host/path/index.html</code>)<br />
– Cache files are stored in <code>/wp-content/uploads/simple-page-cache/</code><br />
– Drop-in (<code>advanced-cache.php</code>) for maximum speed before WordPress loads<br />
– <strong>Nginx configuration generation</strong> for direct cache serving<br />
– <strong>Automatic cache clearing</strong> when posts/pages are updated<br />
– <strong>E-commerce integration</strong> with intelligent cache clearing for:<br />
  – WooCommerce (orders, stock updates, product changes)<br />
  – Easy Digital Downloads (purchases, download updates)<br />
  – BigCommerce for WordPress (product updates)<br />
  – Generic e-commerce plugins (product post types)<br />
– Automatic detection of dynamic pages (cart, checkout, account, wishlist) for:<br />
  – WooCommerce<br />
  – BigCommerce for WordPress<br />
  – Easy Digital Downloads<br />
  – iThemes Exchange<br />
  – Jigoshop<br />
  – WP-Shop<br />
– Detected dynamic pages are automatically excluded from caching<br />
– Manual cache clearing via admin bar button<br />
– <strong>Nginx config regeneration</strong> via admin bar button<br />
– Performance comments in cached HTML files<br />
– No complex settings, no database writes</p>
<h3>Nginx Configuration</h3>
<p>For maximum performance, you can configure nginx to serve cached files directly without PHP processing:</p>
<ol>
<li><strong>Copy the nginx configuration</strong> from <code>/wp-content/uploads/simple-page-cache/nginx.conf</code></li>
<li><strong>Add the configuration</strong> to your nginx server block for your domain</li>
<li><strong>Test nginx configuration</strong>: <code>sudo nginx -t</code></li>
<li><strong>Reload nginx</strong>: <code>sudo systemctl reload nginx</code></li>
</ol>
<p>The nginx configuration includes:<br />
– Internal location block for serving cached files<br />
– Automatic cache bypass for logged-in users<br />
– Automatic cache bypass for requests with query strings<br />
– Debug headers to identify cache hits</p>
<p><strong>Benefits of nginx direct serving:</strong><br />
– Faster response times (no PHP processing)<br />
– Lower server load<br />
– Better scalability<br />
– Direct file serving from disk</p>
<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><strong>Path-based cache structure</strong>: 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><strong>Automatic cache clearing</strong>: When posts or pages are updated, the plugin efficiently clears cache using the new path-based structure and scans for related content.</li>
<li><strong>E-commerce integration</strong>: 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><strong>Performance comments</strong>: Each cached HTML file includes a comment with timestamp and host information for debugging and transparency.</li>
<li><strong>Nginx integration</strong>: 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>

<p>Improve the performance of your site by serving your feeds as static (XML) files.</p>
<h4>WARNING</h4>
<p>If you are not confident with creating/editing files or changing file permissions on your web server, this plugin may not be for you.</p>
<h4>Advantages</h4>
<ul>
<li>Reduces server processing load (reduces PHP and MySQL processing)</li>
<li>Increases server response time (server promptly returns the feed, no need to wait for PHP or MySQL)</li>
<li>Faster downloads (presuming you have compression configured on your web server)</li>
<li>Improves uptime (static files can continue to be served even if PHP or MySQL are offline)</li>
</ul>
<h4>Supported Feeds</h4>
<p>The Static Feed plugin can be used for any of the standard WordPress feeds as well as other feeds added by plugins such as <a href="https://wordpress.org/extend/plugins/powerpress/" rel="ugc">Blubrry PowerPress</a>.</p>
<p>Here’s a brief list:</p>
<ul>
<li>RSS2 (default) Feed (example.com/feed/)</li>
<li>RSS 0.92 Feed (example.com/feed/rss/)</li>
<li>RDF Feed (example.com/feed/rdf/)</li>
<li>Atom Feed (example.com/feed/atom/)</li>
<li>Podcast Feed (example.com/feed/podcast/)</li>
</ul>
<p>Category, tag and comment feeds are currently not supported.</p>
<h4>How does it work?</h4>
<p>Anytime you modify a blog post, the <strong>Static Feed</strong> plugin stores the latest versions of your feeds as XML files on your web server. These locally saved XML files are then served directly by the web server, avoiding unnecessary PHP/MySQL processing.</p>
<h4>Two Ways Static Feed can serve your feeds</h4>
<ol>
<li>
<p>As XML files (e.g. example.com/feed.xml)</p>
<ul>
<li>format commonly used by Movable Type blogs</li>
</ul>
</li>
<li>
<p>As permalinks (e.g. example.com/feed/)</p>
<ul>
<li>format used by WordPress when using the Permalinks feature</li>
</ul>
</li>
</ol>
<h4>Note about Permalink Feeds</h4>
<p>To use this plugin with your existing Permalink feeds (example.com/feed/), your .htaccess file needs to be writable. If your .htaccess file is not writable, the Static Feed plugin will give you instructions how to manually update your .htaccess file. If you cannot modify your .htaccess file, then you’re not going to be able to use this plugin for Permalink feeds.</p>
<h4>This plugin is not for everyone</h4>
<p>If you are using a feed hosting service such as FeedBurner or if your feed includes content that is generated by other factors (such as a star rating plugin), then this plugin is not for you.</p>
