CLI Commands

Warm All URLs

php bin/magento cloudcommerce:cache:warm

Warm Specific Store

php bin/magento cloudcommerce:cache:warm --store-id=1

Warm Single URL

php bin/magento cloudcommerce:cache:warm --url="https://example.com/page.html"

Check Cache Status

php bin/magento cloudcommerce:cache:warm --check-cache
php bin/magento cloudcommerce:cache:warm --url="https://example.com/page.html" --check-cache

Cache Management

The module creates a custom cache type "CloudCommerce URL Collection" that appears in: System > Cache Management

This cache stores collected URLs and can be flushed independently from other cache types.

How It Works

1. URL Collection - Gathers URLs from categories, products, CMS pages, and custom URLs
2. Cache Check - Uses Magento's cache identifier to check if pages are already cached
3. Smart Warming - Only makes HTTP requests to uncached pages
4. Multi-Store - Processes each store view separately with store-specific URLs
5. Cron Automation - Runs automatically based on configured schedule

Performance Features

• Cache-First Approach - Checks cache before making HTTP requests
• URL Collection Caching - Avoids repeated database queries
• Store-Specific Processing - Separate cache keys per store
• Efficient File Checking - Direct cache file existence checks
• Smart Skipping - Skips already cached pages

Logging

Logs are written to var/log/cloudcommerce_cachewarmer.log with detailed information:

• Cache warming results
• Cache status checks
• Error messages
• Performance metrics

Technical Details

• Cache Key Generation - Uses Magento's IdentifierForSave for accurate cache keys
• File Cache Detection - Checks var/page_cache/mage--*/mage---{cacheKey} files
• Multi-Store Support - Store-specific URL collection and base URLs
• Error Handling - Comprehensive exception handling and logging

Requirements

• Magento 2.4+
• PHP 8.0+
