Informations about the package varnish-force-flush
Nx6_VarnishPurge
Magento 2 module that adds a manual "force flush" action for the Varnish full page cache to the admin panel — for the times when Magento's own cache invalidation isn't enough and you need to blow away the entire Varnish cache right now.
| Package | nx6/varnish-force-flush |
| Module | Nx6_VarnishPurge |
| Version | 0.1.0 |
Installation
Configure the Varnish backend host/port under Stores › Configuration › Advanced › System › Full Page Cache (the standard Magento Varnish settings) before using either button.
Where the buttons appear
- Stores › Configuration › Advanced › System › Full Page Cache — a
Force Purge button next to the Varnish settings. Runs over AJAX and shows a
JSON
{success, message}result inline. - System › Tools › Cache Management — a Force Varnish Flush button right
after Flush JavaScript/CSS Cache. It only shows when Varnish is the configured
caching application (
system/full_page_cache/caching_application= Varnish) and the admin user holds the ACL. Behaves like Magento's own flush buttons: performs the purge, sets a success/error notice, redirects back.
How it works
Both buttons call the same operation: an HTTP PURGE request to the configured
Varnish backend (system/full_page_cache/varnish/backend_host /
backend_port) carrying X-Magento-Tags-Pattern: .*, which tells Varnish to
discard its entire cache. The request and response are logged for
troubleshooting.
| File | Role |
|---|---|
Model/VarnishPurger.php |
The purge itself (the cURL PURGE request); shared by both entry points. |
Model/VarnishPurgeResult.php |
Immutable {success, message} value object. |
Controller/Adminhtml/Varnish/Purge.php |
Config-page button — AJAX, returns JSON. |
Controller/Adminhtml/Cache/Purge.php |
Cache Management button — GET action, admin notice + redirect. |
Block/Adminhtml/Cache/Additional.php |
Extends core Magento\Backend\Block\Cache\Additional to add the Varnish visibility / ACL checks. No core files are modified — the template is swapped via layout XML. |
etc/acl.xml |
Nx6_VarnishPurge::varnish_purge gates both buttons. |
Compatibility
Magento 2.4.x, PHP 8.3+. Requires Varnish configured as the full page cache application.
