<p><strong>Key features:</strong></p>
<ul>
<li>Line-by-line caching of HTML pages.</li>
<li>Flexible settings: select which page types to cache.</li>
<li>Automatic cache clearing when content is updated.</li>
<li>Cache status displayed as an HTML comment at the beginning of the file.</li>
<li>Cache statistics: file size and number of files.</li>

<li>Compatibility with custom post types.</li>
</ul>
<h3>Usage</h3>
<p>After activation:</p>
<pre><code>Go to Settings <span aria-hidden="true" class="wp-exclude-emoji">→</span> Mi13 Cache.

Configure the settings:

    Select page types to cache (home page, posts, pages, categories, archives, custom types).

    Set the cache lifetime (in seconds; default is 86 400 s / 24 hours).

    Clear the cache manually using the Clear Cache button (if needed).

Save the settings.
</code></pre>
<p>You can check the cache status in the page source code:</p>
<pre><code>Open the page source code (press Ctrl+U or right-click <span aria-hidden="true" class="wp-exclude-emoji">→</span> “View Page Source”).

Look for a comment at the very beginning of the HTML file, like this: <h3>Settings</h3>
Page types — select which content types to cache.

Cache lifetime — the interval in seconds after which the cache expires.

Clear cache — a button to manually clear all cached files.<h3>HTML comment format</h3>
</code></pre>
<p>The plugin adds an HTML comment with information to the beginning of each cached file: </p>
<h3>Limitations</h3>
<p>Caching does not apply to:</p>
<pre><code>authenticated users;

the admin panel;

404 pages;

search pages (?s=...);

RSS feeds (/feed/);

AJAX requests;

POST requests;

URLs with GET parameters (except paged for pagination).<h3>Troubleshooting</h3>
</code></pre>
<p>Issue: the cache is not created.<br />
Solution: make sure that:</p>
<pre><code>define('WP_CACHE', true) is present in wp-config.php;
WordPress has write permissions for /wp-content/cache/mi13-cache/.
</code></pre>
<p>Issue: pages do not update after editing.<br />
Solution: manually clear the cache on the settings page.</p>
<p>Issue: access permission error when clearing the cache.<br />
Solution: check file permissions in the cache directory.</p>
<h3>Security</h3>
<pre><code>Permission check (manage_options) before clearing the cache.

Caching disabled for authenticated users.

Exclusion of system pages (404, search, feed, etc.).

Use of the secure WordPress API for file system operations.<h3>Directory structure</h3>
Cached files are saved in: /wp-content/cache/mi13-cache/

Each file has the .html extension and a name corresponding to the page URL.

<p>This plugin is the control panel for ModPageSpeed — a web server optimization module for nginx and Apache. ModPageSpeed must be installed and running on your server for this plugin to function. It is not a standalone caching plugin.</p>
<p>The plugin does three things:</p>
<ol>
<li><strong>Enables full-page caching</strong> — adds <code>Cache-Control: public, max-age=N</code> to anonymous page responses (WordPress does not send this by default), with explicit bypasses for logged-in users, WooCommerce cart/checkout/account pages, search, feeds, and 404s.</li>
<li><strong>Keeps the cache fresh</strong> — calls the ModPageSpeed purge API when you publish, update, or delete content, when comments change, when stock levels change, and when terms or theme settings change.</li>
<li><strong>Gives you control in WP Admin and WP-CLI</strong> — per-post-type TTLs, cookie bypass list, excluded URL patterns, a first-run setup wizard, and <code>wp pagespeed flush|status|test-connection</code> commands.</li>
</ol>
<p>Works with both ModPageSpeed product lines (auto-detected), with one important difference:</p>
<ul>
<li><strong>ModPageSpeed 2.0</strong> caches full HTML pages itself — the plugin’s headers and purge calls drive the module’s page cache directly.</li>
<li><strong>mod_pagespeed / ngx_pagespeed 1.1</strong> does not cache HTML (it is a streaming rewriter; its in-place optimization caches only images, CSS, and JS). Full-page caching on 1.1 requires an external cache layer in front (nginx <code>proxy_cache</code>, Varnish, or a CDN) plus <code>ModifyCachingHeaders off</code> or <code>DownstreamCachePurgeLocationPrefix</code> — with 1.1’s default <code>ModifyCachingHeaders on</code>, the module replaces this plugin’s Cache-Control header on rewritten HTML. On 1.1, the plugin’s purge calls evict optimized sub-resources and metadata, not HTML pages.</li>
</ul>
<h4>Server requirements</h4>
<ul>
<li>ModPageSpeed 1.1 (v1.15.0+r3 or later) or ModPageSpeed 2.0 (v2.0.0 or later) installed on your web server.</li>
<li>For 2.0: the worker admin API enabled (<code>--api-port</code>).</li>
<li>For full logged-in-user correctness an nginx cookie-bypass map block is required — the setup wizard provides a copy-paste snippet and verifies it.</li>
</ul>
<h4>WP-CLI</h4>
<ul>
<li><code>wp pagespeed flush [--url=<url>]</code> — purge the home page (and posts page), or one specific URL on this site.</li>
<li><code>wp pagespeed status</code> — detected product, version, license tier, purge prerequisites, and last-purge status.</li>
<li><code>wp pagespeed test-connection</code> — verify the admin API is reachable and correctly configured (read-only, never purges).</li>
</ul>
<h4>License</h4>
<p>This plugin is free software, licensed under the GNU General Public License v2.0 or later. The full GPL-2.0 license text is bundled with the plugin in the LICENSE file.</p>
<h3>Third Party Services</h3>
<p>This plugin makes HTTP requests to the operator-configured ModPageSpeed admin API URL. Data sent includes page URLs (for cache purging) and an API key (for authentication). No data is sent to We-Amp or any third party.</p>
