Holographic Extreme Cache

설명

Holographic Extreme Cache is a simple, yet powerful, static page caching plugin with safe defaults.

It includes static HTML page caching, smart cache clearing, safe WooCommerce exclusions, debug response headers, a basic preload system, a cache health check, safe HTML minification, WordPress emoji disabling, browser cache helper rules, a homepage speed test, cache diagnostics and an uninstall cleanup option.

Privacy

Holographic Extreme Cache does not collect analytics, does not track visitors and does not send site data to a third-party service.

The plugin stores cache files, configuration helper files and optional log files inside its own folder under the WordPress uploads directory. Logging is off by default.

Uninstall

The plugin can remove its settings, cache files, configuration files, log files and scheduled events on uninstall if the uninstall cleanup option is enabled before uninstalling.

If uninstall cleanup is not enabled, settings and generated files are left in place so the site owner can remove or inspect them manually.

FAQ

Does this cache logged-in users?

No. Logged-in users are bypassed by default.

Does this support WooCommerce?

The plugin includes safe WooCommerce exclusions for cart, checkout, account and session URLs/cookies.

Does it edit wp-config.php automatically?

Only after an administrator clicks the Setup tab button to enable WP_CACHE. It does not silently edit wp-config.php on activation.

Does it cache admin pages?

No. WordPress admin pages, login pages, AJAX requests and REST API requests are excluded.

What should I do after changing a theme, plugin or important content?

Use Clear Cache from the Holo-Cache dashboard or admin bar. The plugin also clears relevant cache automatically for common content changes.

변경이력

1.0.47

  • Updated free admin screens so main content panels, settings sections, help sections and tables use the available page width.
  • Removed unnecessary dashboard status cards for cache delivery and WooCommerce protection.
  • Changed the disabled-WP-Cron preload fallback so the Cache tab loads first, then processes one safe batch asynchronously.

1.0.46

  • Rebuilt the free plugin help page with clearer sections for setup, dashboard, page cache, preload, optimisation, exclusions, health checks and troubleshooting.
  • Removed unnecessary preload warning wording while keeping the WP-Cron-disabled guidance and sample server cron command.

1.0.45

  • Added WP-Cron-disabled preload handling with a clear admin warning, help-page guidance, a sample server cron command, manual safe batch processing and controlled admin-page batch fallback.
  • Updated the setup notice so an authenticated HEC admin action marks setup as handled.

1.0.44

  • Updated the cache speed-check wording so a successful result clearly states that the HEC HIT response header confirmed cached homepage delivery.

1.0.43

  • Rebuilt the free cache speed-test flow so the warm-up and final proof request use the same canonical homepage cache item.
  • Improved advanced-cache.php speed-test URL normalisation so the final request reads the warmed homepage cache file instead of refreshing it.
  • Removed earlier diagnostic/fallback HIT handling so speed-test success depends on the HEC cache response header.

1.0.41

  • Fixed the homepage speed check so warm-up and final check use the same canonical homepage cache item.
  • Fixed speed-test cache delivery so the final request reports HIT only when an existing static cache file is served with the HEC response header.

1.0.39

  • Restored reliable HEC response-header detection for the cache speed check.

1.0.29

  • Improved cache lookups for Cloudflare and reverse-proxy environments so cached files can be served consistently across HTTP/HTTPS scheme detection differences.

1.0.28

  • Improved cache key stability for PHP fallback and drop-in cache delivery.

1.0.27

  • Improve cache reader file validation and native file-read fallback for PHP fallback cache hits.

1.0.26

  • Improved cache file writes so HTML and metadata are written atomically together.
  • Added a safer direct filesystem fallback for cache writes where needed.

1.0.27

  • Improve cache reader file validation and native file-read fallback for PHP fallback cache hits.

1.0.26

  • Improved cache speed test requests so warm-up and cached checks use a safe HEC test marker while still sharing the normal homepage cache key.
  • Expanded free preload URL collection so all published posts and pages can be queued instead of only the first small set.

1.0.23

  • Improved drop-in/config synchronisation and speed-test diagnostics.

1.0.22

  • Changed the homepage speed test to use a request-level cache bypass instead of toggling the global cache setting.
  • Added explicit HEC bypass handling for speed-test URLs so final cache checks can test the live cache path more accurately.
  • Kept internal speed-test and bypass query markers out of cache keys.

1.0.21

  • Improved the cache speed check so its HEC test marker survives proxies by using a safe internal query marker as well as request headers.
  • Normalised HEC internal speed-test query markers out of cache keys so tests check the normal homepage cache file.
  • When basic preload is enabled, clearing all cache now automatically queues preload so site owners do not have to remember to press Start Preload after every clear.

1.0.20

  • Improved preload reliability so queued URLs are warmed in background batches without slowing the admin request.
  • Added direct static-cache writing during preload and homepage speed warm-up when loopback requests do not expose HEC runtime headers.
  • Improved preload status reporting with processed, remaining and last-result details.

1.0.19

  • Improved speed test detection so HEC debug headers are requested explicitly and Cloudflare DYNAMIC is no longer treated as a cache result.

1.0.18

  • Fixed cache key handling behind Cloudflare/reverse proxies so cache writes and drop-in reads use the same request scheme.
  • Improved drop-in diagnostics for cache speed checks.
  • Increased the free preload batch size to 20 URLs.

1.0.16

  • Improved advanced-cache.php HTTPS detection behind Cloudflare, reverse proxies and load balancers so cached files are served with the same scheme used when they are written.
  • Improved cache-speed-test reliability for proxied HTTPS sites where server variables report HTTP internally.

1.0.15

  • Added request-local settings caching to reduce repeated option sanitisation during admin and frontend requests.

1.0.6

  • Improved homepage speed test sequencing so cache-off, warm-up and cache-on measurements use the same clearer comparison flow.

  • Fixed final Plugin Check findings for cached HTML output and admin request handling.
  • Improved scanner-readable nonce validation for admin tab/message and settings requests.

1.0.4
