Title: Cacheability Author: Danila Vershinin Published: 8 avril 2022 Last modified: 24 juin 2026 --- Recherche d’extensions ![](https://ps.w.org/cacheability/assets/icon-256x256.png?rev=2707233) # Cacheability Par [Danila Vershinin](https://profiles.wordpress.org/dvershinin/) [Télécharger](https://downloads.wordpress.org/plugin/cacheability.2.2.0.zip) * [Détails](https://fr-be.wordpress.org/plugins/cacheability/#description) * [Avis](https://fr-be.wordpress.org/plugins/cacheability/#reviews) * [Installation](https://fr-be.wordpress.org/plugins/cacheability/#installation) * [Développement](https://fr-be.wordpress.org/plugins/cacheability/#developers) [Support](https://wordpress.org/support/plugin/cacheability/) ## Description Cacheability makes your WordPress site a better HTTP citizen, improving SEO and cache efficiency. #### Free Features **Soft 404 Fix** WordPress returns HTTP 200 for empty search results, invalid tag pages, and empty category archives. Google marks these as « soft 404 » errors in Search Console, hurting your SEO. Cacheability fixes this by returning proper 404 status codes when: * Search results are empty (`/?s=nonexistent`) * Tag archives are empty (`/tag/nonexistent/`) * Category archives are empty * Author archives are empty **Smart Cache-Control Headers** Automatically adds `s-maxage` headers so Varnish, NGINX, and CDNs can cache your pages efficiently without affecting browser caching behavior. * Search/404 pages: 1 hour cache * All other pages: 1 year cache (your purge plugin handles invalidation) #### Cacheability Pro Upgrade to [Cacheability Pro](https://www.getpagespeed.com/web-apps/cacheability-pro) for advanced features: * **Cache Warming** — Automatically warm pages after purging so visitors never hit cold cache * **Conditional GET (304)** — Return 304 Not Modified for unchanged content, saving bandwidth * **ESI Support** — Cache pages with dynamic nonces (comments, login forms) * **Rate-Limit Safe** — Smart request queuing to avoid 429 errors * **Sitemap Warming** — Warm all pages from sitemap after full purge * **WP-CLI Commands** — `wp cacheability warm` and more * **Priority Support** — Get help when you need it [Get Cacheability Pro ](https://www.getpagespeed.com/web-apps/cacheability-pro) ## Installation 1. Upload to `/wp-content/plugins/cacheability/` 2. Activate the plugin through the ‘Plugins’ menu 3. That’s it! No configuration needed. The plugin works automatically. You can view the settings page under Settings Cacheability. ## FAQ ### Is it compatible with caching plugins? Yes! Cacheability works alongside any caching solution including WP Super Cache, W3 Total Cache, WP Rocket, Varnish, NGINX FastCGI cache, and CDNs like Cloudflare. ### Does it slow down my site? No. Cacheability adds minimal overhead — it just sets proper HTTP headers and status codes. ### What’s the difference between free and Pro? The free version fixes soft 404s and adds cache headers. Pro adds cache warming ( automatically re-caches pages after purging), conditional GET responses (304), and ESI support for dynamic content. ### Do I need Varnish HTTP Purge plugin? For the free version, no. For Cacheability Pro’s cache warming feature, we recommend [Varnish HTTP Purge](https://wordpress.org/plugins/varnish-http-purge/) or similar purge plugin. ### How do I stop a specific page from being cached? Return true from the `cacheability_skip` filter for that request. The plugin then gets out of the way and sets no Cache-Control, so a transactional template’s own header() stays authoritative. This is deterministic regardless of PHP output buffering. Example for a payment-success page: ``` add_filter( 'cacheability_skip', function ( $skip ) { return is_page( 'checkout-thank-you' ) ? true : $skip; } ); ``` ## Avis Il n’y a aucun avis pour cette extension. ## Contributeurs & développeurs « Cacheability » est un logiciel libre.

Return true to make the plugin get out of the way for a request, so it sets no Cache-Control and a transactional template’s own header() (or an earlier wp_headers filter) stays authoritative. Deterministic regardless of output buffering. Use it for payment-success, checkout-confirmation, and other pages that must not inherit the blanket cache header. #### 2.1.0 * New: Prevents Google’s « Soft 404 » indexing flag on tag/category archives that don’t currently have posts assigned, and on search-results pages. #### 2.0.1 * Fixed duplicate Cache-Control headers when another plugin sets headers via PHP header() function #### 2.0.0 * Major update: Streamlined free version * Cache warming, conditional GET, and ESI moved to Cacheability Pro * Added settings page with Pro feature overview * Improved soft 404 detection (now includes category and author archives) * Code modernization and cleanup #### 1.1.7 * Fixed a PHP notice when used together with older versions of Varnish HTTP Purge plugin and WP-Rocket integrations #### 1.1.6 * Fixed a PHP fatal error when used together with older versions of Varnish HTTP Purge plugin and WP-Rocket integrations #### 1.1.3 * Fixed some PHP warnings #### 1.1.0 * Added cache warmup feature for updated content #### 1.0.0 * Initial release ## Méta * Version **2.2.0** * Last updated **il y a 3 jours** * Active installations **100+** * WordPress version ** 5.0 ou plus ** * Tested up to **7.0** * PHP version ** 7.0 ou plus ** * Language * [English (US)](https://wordpress.org/plugins/cacheability/) * Tags * [404](https://fr-be.wordpress.org/plugins/tags/404/)[cache](https://fr-be.wordpress.org/plugins/tags/cache/) [performance](https://fr-be.wordpress.org/plugins/tags/performance/)[seo](https://fr-be.wordpress.org/plugins/tags/seo/) [varnish](https://fr-be.wordpress.org/plugins/tags/varnish/) * [Vue avancée](https://fr-be.wordpress.org/plugins/cacheability/advanced/) ## Notes No reviews have been submitted yet.
