Panth Cache Manager for Magento 2 — Smart Cache Invalidation & Automated Warmup with Concurrent Requests
Keep your Magento 2 full-page cache hot and your store fast — smart cache invalidation on product, category, and CMS save events, plus automated cron-driven warmup using concurrent
curl_multirequests, with a full admin warmup log grid for visibility.
Panth Cache Manager is a production-grade cache optimization extension for Magento 2 and Hyva storefronts. Instead of flushing the entire full-page cache whenever a merchant edits a single product, Cache Manager invalidates only the tags that actually changed. On top of that, it runs a scheduled warmup crawler that re-primes the most important pages — home, categories, products, and CMS — in parallel batches, so real customers never hit a cold cache. Every warmup request is logged in an admin grid with HTTP status and response time, so you can see exactly what is happening.
Built to MEQP standards and compatible with Magento 2.4.6 — 2.4.8 on PHP 8.1 — 8.4, Cache Manager is part of the Panth Infotech extension suite and integrates cleanly with Hyva and Luma themes.

Default Magento 2 cache handling is aggressive: saving a single product can blow away large portions of the full-page cache, forcing the very next visitor to wait for a cold render. On larger catalogs this shows up as intermittent TTFB spikes and poor Core Web Vitals.
Panth Cache Manager fixes this in two ways:
- Smart invalidation — only the relevant cache tags are cleared on entity save, so unrelated pages stay hot.
- Automated warmup — a cron job re-crawls the important pages in parallel, so even when cache does expire, the first real customer hits a warm page.
The result is consistently fast page loads, better Core Web Vitals, and less server load.
- Product save — clears only the F440 affected product's cache tags (not the entire FPC)
- Category save — clears the specific category tags
- CMS save — clears only the affected page/block tags
- Per-entity toggles — enable or disable invalidation per entity type
- Cron-driven — runs on a configurable schedule (default every 6 hours)
- Concurrent requests — uses PHP
curl_multito send N requests in parallel - Configurable concurrency — tune parallel batch size to your server capacity
- Selectable page types — Home, Category pages, Product pages, CMS pages
- Store-aware — respects Magento scope and base URL
- Full admin grid — every warmup request recorded
- HTTP status — 200, 404, 500, etc.
- Response time (ms) — diagnose slow pages at a glance
- Page type, URL, timestamp — filter, sort, and export
- Custom TTL per store view
- Default: 86400 seconds (24 hours)
- MEQP compliant — passes Adobe's Magento Extension Quality Program
- Hyva and Luma compatible — works with any frontend theme
- No core hacks — pure observer and plugin architecture
- Composer-installable — no manual file copying

Use built-in filters and sorting to find slow pages, failed requests, or audit warmup frequency.
| Issue | Cause | Resolution |
|---|---|---|
| Warmup cron never runs | Magento cron not configured | Verify bin/magento cron:run is scheduled in system crontab |
| All warmup requests fail | Server cannot reach its own URL | Check firewall, SSL, and base URL reachability from the server |
| Smart invalidation has no effect | Master or per-entity toggle off | Set both Enable Smart Invalidation and the entity toggle to Yes |
| No URLs collected | No page types selected | Pick at least one page type in Pages to Warm Up |
| Warmup too slow | Concurrency too low | Raise Concurrent Requests (test gradually — 5, 10, 20) |
| Warmup overloads server | Concurrency too high | Lower Concurrent Requests and/or schedule off-peak |
Yes. Smart invalidation cleans Magento cache tags which Varnish honors via the standard Magento Varnish integration. Warmup simply issues HTTP GET requests, which Varnish caches like any other visitor.
Yes. Cache Manager operates at the cache layer, not the frontend, so it is theme-agnostic. It fully supports Hyva and Luma.
Warmup sends ordinary HTTP GET requests from the server. If you want to exclude warmup traffic, filter by User-Agent or IP in your analytics tool. You can customize the User-Agent via a plugin on the warmup service if needed.
Warmup runs on cron, not on every request. Typical concurrency of 5 parallel requests every 6 hours is negligible. Tune Concurrent Requests for your infrastructure.
No. That is the point. Cache Manager invalidates only the tags for the saved entity. Unrelated pages remain cached.
The default warmup covers home, categories, products, and CMS. Custom URL providers can be added via DI by extending the URL collector service.
No. Cache Manager sits on top of Magento's Full Page Cache — it invalidates smarter and keeps it warm.
The log grows with every warmup cycle. For large stores, consider adding a periodic cleanup cron (roadmap) or truncate panth_cache_warmup_log manually as needed.
Yes. mage2kishan/module-core is a free, required dependency and is pulled in automatically by Composer.
Yes. All settings respect Magento's scope hierarchy (default → website → store view), and warmup collects URLs per store view.
