IndiaTVDNA Turbo Cache Lite

IndiaTVDNA Turbo Cache Lite is a standalone free performance plugin. Free functionality is real and usable; advanced Full modules are not hidden behind locked switches in the Lite ZIP.

Free working features:
* Anonymous page cache with dynamic-session bypasses.
* Automatic cache invalidation and manual purge.
* GZIP pre-compressed cached HTML when supported by the server.
* Conservative HTML cleanup.
* Conservative CSS Minify using generated cache copies; original files are never edited.
* Local @font-face font-display: swap in generated CSS copies.
* Image and iframe lazy loading through WordPress core lazy-loading APIs.
* Basic Auto Optimize, manual preload, Performance Doctor and cache self-test.
* Manual expired-transient cleanup.
* Basic Cloudflare integration: token verification, zone detection, manual purge and optional content-change auto purge.
* User-configured CDN URL Delivery for eligible wp-content/wp-includes assets.
* Local Smart Intelligence that inspects the current theme/plugin stack for common optimizer conflicts without sending site data to an AI service.
* Live cache count/size and generated asset statistics.

Full-version preview cards explain advanced functionality and show estimated potential performance ranges. Those ranges are informational estimates, not guarantees. Results depend on hosting, theme, plugins, media, visitor location, cacheability and existing optimization.

The separate IndiaTVDNA Turbo Cache Full package adds advanced functionality such as early advanced-cache.php delivery, stale/stampede protection, AVIF/WebP background conversion, Redis/Memcached auto discovery, adaptive smart preload, advanced Cloudflare Full-Page Edge Cache rule management, advanced asset exclusions/warm/rebuild controls, rollback/self-healing and deeper diagnostics.

Recent Full package development highlights

The following items describe the separate IndiaTVDNA Turbo Cache Full package and are not included in the Lite ZIP unless a Lite feature above explicitly states otherwise.

• Performance Doctor now coordinates Smart CSS fixes with the governed background worker instead of claiming success before the scheduled job has actually run.
• Object Cache recovery can clear stale fail-fast/circuit state after an explicit successful backend repair and health check, while real backend failures continue to fail safely.
• Admin-side object-cache diagnostics distinguish an intentionally disabled wp-admin persistent-cache policy from a genuinely unhealthy Redis/Memcached backend.
• Added bounded local Real User Monitoring trends and performance evidence without adding a second beacon or an external analytics service.
• Expanded evidence-first font and CLS intelligence with conservative same-origin/configured-CDN preload decisions and no guessed font metric overrides.
• Added shared-hosting safety depth including role/cookie cache-isolation probes, richer cache diagnostics and demand-driven image processing under the existing load governor.
• Added runtime canary/regression protections for high-risk optimization paths so failed experiments can be rejected without globally disabling unrelated settings.
• Added Cloudflare managed edge self-heal for previously plugin-owned rules only; first-time edge rule installation remains an explicit administrator action.
• Image processing is demand-driven and governed with CPU quiet gaps, source fingerprints and duplicate-work prevention instead of a permanent conversion cron loop.
• Background heavy jobs are coordinated through a global one-slot scheduler and additional locks/cooldowns so preload, image, asset, database and diagnostic workers do not pile onto the same minute.
• Cache-coherence hardening performs targeted invalidation after content changes and protects public delivery while required invalidation work is pending.

External services

IndiaTVDNA Turbo Cache Lite does not automatically send site or visitor data to IndiaTVDNA.

Cloudflare

Cloudflare integration is optional and OFF by default. It is used only when an administrator explicitly configures/uses the Cloudflare controls. The plugin may send authenticated requests to Cloudflare’s API to verify the configured Cloudflare credential, find the zone for the current site and purge Cloudflare cache. These requests include the credential and site/zone information needed for the requested operation. When the administrator chooses legacy Global API Key authentication, the matching Cloudflare account email is also sent because Cloudflare requires it for that legacy authentication method.

User-configured CDN

CDN URL Delivery is optional and OFF by default. The plugin does not choose or create a CDN provider. If an administrator enters a CDN hostname and enables delivery, eligible static asset URLs are rewritten to that hostname. Visitors’ browsers may then send normal web requests (such as IP address, user agent and requested asset URL) to the administrator-selected CDN provider. Review the privacy policy and terms of the CDN provider you choose.

IndiaTVDNA website links

The admin interface contains optional Full-version links to https://indiatvdna.com/. Data is sent to that website only when an administrator chooses to follow a link, according to the website’s own terms and privacy policy.

The plugin also adds suggested text to WordPress’s Privacy Policy Guide for the optional Cloudflare/CDN features.
