<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>Purgely manages caching behavior for WordPress sites using Fastly as an edge caching solution. The plugin exposes useful<br />
APIs to help control how pages on your site are cached, as well as provides sane defaults to make this a plug and play<br />
solution for Fastly cache management.</p>
<p>The plugin handles the following:</p>
<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<br />
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>
<p>Each of these items have sane defaults with ways to override them and configure them to your liking.</p>
<p>Additionally, the plugin exposes a WP CLI command to provide more flexible purging options.</p>
