## 説明

WP Power Cache is designed for developers and site owners who need extreme speed
without the bloat of traditional caching plugins. It converts your dynamic WordPress
pages into static HTML files, serving them directly from the filesystem to bypass
heavy PHP and MySQL processing.

**Key Features:**

**Core Performance & Caching**
 * **Static HTML Generation:** Automatically creates,
minifies, and stores HTML snapshots for optimized, lightweight output. * **Smart
Cache Clearing:** Intelligently invalidates only specific post cache and the homepage
upon updates to maintain efficiency. * **Cache TTL/Expiration System:** Provides
fine-grained control over cache lifetimes to ensure content freshness. * **Advanced
URL Exclusion:** Supports both regex and string-based exclusions for precise caching
control. * **Modern Lazy Loading:** Enhances page speed with high-performance asset
loading and zero jQuery dependency.

**Developer & Admin Tools**
 * **Developer Mode & Performance Metrics:** Dedicated
real-time monitoring tools to track and optimize site performance. * **Admin Bar
Integration:** Provides the ability to clear the full site cache directly from the
WordPress admin bar. * **Enhanced System Diagnostics:** Built-in checks for permissions,
disk space, and permalink compatibility with advanced debugging insights. * **Full
Audit Logging:** Complete transparency with tracking for all cache activity and 
administrative actions.

**Security & Architecture**
 * **Secure Storage & Protection:** Utilizes hashed 
directories and directory traversal protection to prevent unauthorized file access.

## インストール

 1. Upload the `wp-power-cache` folder to the `/wp-content/plugins/` directory.
 2. Activate the plugin through the ‘Plugins’ menu in WordPress.
 3. Navigate to **Power Cache** in the admin sidebar to configure settings.
 4. Ensure your Permalinks are set to anything other than “Plain” (Settings > Permalinks).

## FAQ

### Does it clear the homepage when I update a post?

Yes. To ensure your “Latest Posts” sections stay updated, the plugin automatically
purges the homepage (index.html) whenever a single post or page is saved.

### Where are the cache files stored?

Files are stored in a protected sub-folder within the plugin directory using an 
MD5 hashed name for enhanced security.

### Can I clear the cache manually?

Absolutely. You can use the “Empty Entire Website Cache” button in the plugin settings
or the “Power Cache” menu in the WordPress Admin Bar.
