A lightweight plugin for line-by-line caching of WordPress pages. Speeds up site loading by saving static copies of pages.
Mi13 Cache is a simple and effective plugin for caching WordPress pages. It saves HTML pages as files and serves them on subsequent requests, significantly speeding up site loading.

- Line-by-line caching of HTML pages.
- Flexible settings: select which page types to cache.
- Automatic cache clearing when content is updated.
- Cache status displayed as an HTML comment at the beginning of the file.
- Cache statistics: file size and number of files.
- Security: access permission checks and filtering of system pages.
- Compatibility with custom post types.
Usage
After activation:
Go to Settings → 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.
You can check the cache status in the page source code:
Open the page source code (press Ctrl+U or right-click → “View Page Source”).
Look for a comment at the very beginning of the HTML file, like this: <!-- MI13 CACHE --><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>
The plugin adds an HTML comment with information to the beginning of each cached file:
Limitations
Caching does not apply to:
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>
Issue: the cache is not created. Solution: make sure that:
define('WP_CACHE', true) is present in wp-config.php;
WordPress has write permissions for /wp-content/cache/mi13-cache/.
Issue: pages do not update after editing. Solution: manually clear the cache on the settings page.
Issue: access permission error when clearing the cache. Solution: check file permissions in the cache directory.
Security
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.
