Test the setup and your website workflows before enabling it on a production site. Stores eligible anonymous HTML locally. Cookies, query parameters, unverified forms, nonces and private responses remain dynamic. English/German interface. No account or service required. A verified public GET search-form profile can be cached; search results remain dynamic. No CSS/JS/HTML transformations. Local caching and compatibility features are free. Optional services with ongoing operating costs may be considered later; none is included or required. Cache storage must be writable and outside the document root. Another cache owner’s drop-in is never replaced. Multisite and automatic proxy trust are not supported. A limited AdSimple Magazine/Aktivbau Child/AdSimple Client profile has passed isolated tests. Initial isolated profiles with Twenty Twenty-Five 1.5, Astra 4.14.0 and GeneratePress 3.6.1 have also passed cache/content-update checks. Other combinations, premium theme add-ons, consent, commerce, membership and multilingual modes require separate acceptance. Detected WPML, Polylang and TranslatePress are disabled until their adapters are verified. ## Screenshots [⌊The cache dashboard with activation, lifetime, exclusions and local storage status.⌉⌊ The cache dashboard with activation, lifetime, exclusions and local storage status .⌉[ The cache dashboard with activation, lifetime, exclusions and local storage status. ## Installation 1. Back up affected configuration and identify existing page-cache ownership. 2. Install in an isolated WordPress test environment first, keeping the standard ostheimer- performance plugin directory name. 3. Set WP_CACHE to true and OSTHEIMER_PERFORMANCE_CACHE_DIR to a writable private directory outside the document root. 4. Open Settings > Ostheimer Performance and enable caching. 5. Verify MISS/HIT, visitor isolation and content invalidation before a pilot. ## FAQ ### Does this replace every WP Rocket feature? No. This version provides anonymous HTML page caching. It does not include asset optimization, image processing, CDN configuration or cache preloading. ### Which requests stay dynamic? Requests with cookies, query parameters or authentication; editor previews; REST, feeds and sitemaps; private responses; unverified forms and nonce-bearing pages. This conservative policy can reduce the cache hit rate on sites using visitor cookies. ### Does it require an account or send data to a service? No account is required. The cache stores eligible public HTML on the site’s server and does not call an external service, collect visitor analytics or set cookies. ### Where are cache files stored? In a writable private directory outside the real web document root, configured using OSTHEIMER_PERFORMANCE_CACHE_DIR. Check the host’s cleanup/retention policy before using temporary storage. If storage is unavailable, ordinary WordPress rendering continues; inspect setup status before re-enabling a recovered directory. ### Can another cache run alongside it? Use one owner for the page cache. This version refuses foreign advanced-cache.php files and detected competing page caches. It does not replace an object-cache.php drop-in or flush a Redis database. ### What does deactivation or uninstall remove? Deactivation disables caching and removes the verified owned reader. Uninstall additionally removes the plugin’s options and verified owned cache files; unrelated files and directories are preserved. WP_CACHE and the private-directory constant in wp-config. php are not automatically changed. ### Is this suitable for every website? No. Version 0.1.1 is a small initial release with conservative exclusions. It needs a private writable cache directory and manual configuration. Shops, forms, membership, consent and multilingual modes require separate acceptance; detected unsupported language modes keep the engine disabled. A site pilot is not a general compatibility guarantee. ### Where can I get help? Product and agency information: https://www.ostheimer.at/ . Include WordPress/PHP versions, the active theme and plugins, setup status and the X-Ostheimer-Cache header when reporting an issue. Do not post credentials, private cached files or personal data. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “Ostheimer Performance” is open source software.
