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_multi requests, 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.

Why Panth Cache Manager

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.

Key Features

Smart Cache Invalidation

Product save — clears only the 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

Automated Cache Warmup

Cron-driven — runs on a configurable schedule (default every 6 hours)
Concurrent requests — uses PHP curl_multi to 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

Warmup Log Grid

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

Configurable Full Page Cache TTL

Custom TTL per store view
Default: 86400 seconds (24 hours)

Quality & Compatibility

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

How It Works

Smart Invalidation Flow

Admin saves product/category/CMS
        ↓
Observer catches save event
        ↓
Cache Manager computes affected tags
        ↓
Only those tags are cleaned
        ↓
Unrelated pages remain cached

Warmup Flow

Cron triggers (default: every 6 hours)
        ↓
Collect URLs (home, categories, products, CMS)
        ↓
Split into batches of N (configurable concurrency)
        ↓
curl_multi sends batch in parallel
        ↓
Each response logged to panth_cache_warmup_log
        ↓
FPC is now primed for real visitors

Installation

Composer Installation (Recommended)

composer require mage2kishan/module-cachemanager
bin/magento module:enable Panth_Core Panth_CacheManager
bin/magento setup:upgrade
bin/magento setup:di:compile
bin/magento setup:static-content:deploy -f
bin/magento cache:flush

Manual Installation via ZIP

Download the release ZIP from Packagist or GitHub.
Extract to app/code/Panth/CacheManager/.
Ensure Panth_Core is also installed at app/code/Panth/Core/.
Run the commands above from bin/magento module:enable onward.

Verify Installation

bin/magento module:status Panth_CacheManager
# Expected: Module is enabled

Then visit:

Admin → Stores → Configuration → Panth Extensions → Cache Manager

Configuration

All settings live at Stores → Configuration → Panth Extensions → Cache Manager.

General

Setting	Default	Description
Enable Cache Manager	Yes	Master toggle. When No, neither invalidation nor warmup runs.

Full Page Cache

Setting	Default	Description
Cache TTL (seconds)	86400	Lifetime of cached pages. 24 hours by default.

Cache Warmup

Setting	Default	Description
Enable Cache Warmup	Yes	Turn automatic warmup on/off.
Warmup Schedule	`0 /6 * *`	Cron expression — every 6 hours by default.
Pages to Warm Up	All	Multi-select: Home, Category, Product, CMS pages.
Concurrent Requests	5	Parallel `curl_multi` requests per batch.

Cache Invalidation

Setting	Default	Description
Enable Smart Invalidation	Yes	Master toggle for selective cache cleaning.
Invalidate on Product Save	Yes	Clean product cache tags on product save.
Invalidate on Category Save	Yes	Clean category cache tags on category save.
Invalidate on CMS Save	Yes	Clean CMS tags on page or block save.

Warmup Log

Navigate to Panth Extensions → Cache Manager → Warmup Log in the admin sidebar.

The grid shows:

Column	Description
ID	Auto-increment log ID
URL	The page that was warmed
Page Type	home, category, product, cms
HTTP Status	200, 404, 500, etc.
Status	success or failed
Response Time (ms)	Request duration
Warmed At	Timestamp

Use built-in filters and sorting to find slow pages, failed requests, or audit warmup frequency.

Troubleshooting

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

FAQ

Does Cache Manager work with Varnish?

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.

Does it work with Hyva?

Yes. Cache Manager operates at the cache layer, not the frontend, so it is theme-agnostic. It fully supports Hyva and Luma.

Will warmup hit my analytics?

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.

How much server load does warmup add?

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.

Does it flush the full cache?

No. That is the point. Cache Manager invalidates only the tags for the saved entity. Unrelated pages remain cached.

Can I warm custom URLs?

The default warmup covers home, categories, products, and CMS. Custom URL providers can be added via DI by extending the URL collector service.

Does this replace Magento's default FPC?

No. Cache Manager sits on top of Magento's Full Page Cache — it invalidates smarter and keeps it warm.

Is the warmup log pruned automatically?

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.

Does it require Panth Core?

Yes. mage2kishan/module-core is a free, required dependency and is pulled in automatically by Composer.

Is multi-store supported?

Yes. All settings respect Magento's scope hierarchy (default → website → store view), and warmup collects URLs per store view.
