== Frequently Asked Questions ==

= How does Mamba handle WooCommerce product pages? =

Mamba caches individual product pages with full variant support. Each product page is cached separately, and updates to product data (price, stock, description) automatically invalidate the cache. Variable products are handled intelligently, caching each variation combination.

= What happens when I update a product? =

When you update a WooCommerce product (price, stock, description, images), Mamba automatically:

– Purges the product's individual page cache
– Purges any category pages containing that product
– Clears related Store API caches
– Sends purge requests to connected CDNs
– Optionally triggers cache warmup for affected pages

= How does caching work with WooCommerce categories? =

Category and tag pages are cached with pagination support. When products are added/removed from categories, or when category settings change, Mamba purges affected category pages. This ensures category listings always show current product inventory.

= Does Mamba cache the shop page and search results? =

Yes! The main shop page, WooCommerce search results, and all product listing pages are cached. Search results are not cached by default to prevent serving personalized search data, but this can be customized with filters.

= How does Mamba handle WooCommerce sessions and cart data? =

Mamba intelligently excludes dynamic WooCommerce content from caching:

– Logged-in users never see cached pages
– Cart, checkout, and account pages are never cached
– Cart fragments are cached per-session for guests
– Session-based personalization (prices, availability) is respected

= What about variable products and product variations? =

Variable products are fully supported. Each variation combination can be cached separately based on your store's caching rules. Stock changes, price updates, and visibility changes for variations trigger appropriate cache invalidation.

= How does Mamba work with WooCommerce Multilingual? =

Mamba integrates with WPML, Polylang, and WooCommerce Multilingual plugins. Each language gets separate cache variants, ensuring multilingual stores serve correct content to each language audience.

= Can Mamba cache WooCommerce REST API responses? =

Yes, with the Premium version! Store API endpoints (used by WooCommerce Blocks) are cached with proper invalidation. This dramatically speeds up block-based product pages and headless WooCommerce implementations.

= How does Mamba handle inventory changes? =

Stock level changes trigger immediate cache purges for affected products. When orders reduce inventory, Mamba purges the product page and related category pages to ensure accurate stock display.

= What about pricing changes and currency switching? =

Mamba caches different price displays and currencies separately. When pricing rules change or currencies are updated, affected caches are purged. Currency switcher plugins are fully supported.

= How does Mamba optimize WooCommerce database performance? =

Mamba includes 18 automated database cleanup tasks specifically for WooCommerce:

– Expired customer sessions and cart data
– Orphaned order items and metadata
– Unused product attributes and terms
– System order notes and download logs
– Reserved stock cleanup
– HPOS migration cleanup

= Is Mamba compatible with my hosting provider? =

Mamba works with all standard WordPress hosting providers. It uses standard WordPress APIs and doesn't require special server configurations. For optimal performance, we recommend hosts that support Redis or Memcached.

= Does Mamba work with page builders? =

Yes! Mamba has built-in support for Elementor and Breakdance. It automatically detects content changes and purges affected cache entries.

= Can I use Mamba with a CDN? =

Absolutely. Mamba integrates with Cloudflare, Bunny CDN, and generic webhook endpoints. It can also rewrite asset URLs to use your CDN hostname.

= How does Mamba handle cache invalidation? =

Mamba uses intelligent, tag-based invalidation. Instead of clearing entire cache, it only purges affected pages. For example, when a product is updated, only that product's page and related category pages are purged.

= Is the cache persistent across deployments? =

Cache files are stored in `wp-content/cache/mamba/` and persist across deployments. Object cache (if available) also persists. We recommend excluding the cache directory from version control.

= Does Mamba work with WooCommerce HPOS? =

Yes, Mamba is fully compatible with WooCommerce High-Performance Order Storage (HPOS/COT).

= Can I customize cache behavior? =

Yes, extensively! Mamba provides 60+ filters for developers to customize TTL, cache keys, invalidation logic, and more. See our [Developer Reference](docs/api-reference.html) for details.

= What happens if I deactivate Mamba? =

All cache files are safely removed on deactivation. Your original site performance returns to normal. No data is lost, but cached content will need to be regenerated.

= Can I run Mamba on a multisite network? =

Yes! Mamba supports WordPress Multisite with per-site caching. Activate network-wide or per-site as needed.

= How do I monitor cache performance? =

Mamba provides real-time statistics on the **Dashboard** tab, including hit rates, generation times, coverage percentage, and total savings.

= Does Mamba affect SEO? =

No, Mamba improves SEO by making your site faster. Faster sites rank better in search engines. All cache variants are properly handled for SEO.

= Can I exclude certain pages from caching? =

Yes, use the `mamba_cache_bypass` filter or add `define('MAMBA_CACHE_BYPASS', true);` to specific pages.

= How do I clear the cache? =

Use the "Purge All Cache" button in the admin bar or Mamba dashboard. For specific URLs, use "Purge This Page" from the admin bar.

= What about security? =

Mamba follows WordPress security best practices. All admin actions use nonces, input is sanitized, and cache files are protected with .htaccess rules.

= Can I use Mamba with other caching plugins? =

We recommend using Mamba as your primary caching solution. Disable other caching plugins to avoid conflicts.
