Full Page Cache Pro

What it does

For CS-Cart and Multi-Vendor stores on shared hosting or a VPS that need fast pages without Varnish or a higher plan. Finished pages are stored as compressed files, separately per storefront, language, currency, device and URL, and sent to guests early in the request. Signed in customers, carts, wish lists, compare lists and any session data the add-on does not know get a normal page. Forms keep working because each visitor gets a personal token. While the core Varnish cache of 4.21 is active, the add-on switches itself off.

How it works

Install and open any admin page. No files are changed and there is nothing to configure. The first guest gets a normal page, which is checked and stored; the next guests get it from the cache. Changes from the admin panel, vendor panel, imports, the API and orders drop the affected pages at once. The admin page shows the hit rate, disk use and why pages were skipped, and the X-Kv-Fpc header shows HIT, MISS or BYPASS with the reason. A nightly cron job warms your most popular pages.

Features

• PHP and files only: no Varnish, no Redis, no licence plan requirement
• Sent before other add-ons load, which saves most of the time of a page view
• Fails closed: unknown session data means a normal page
• Stored only from clean guest visits, after checks on the finished page
• Personal form token per visitor, added to every page sent
• Separate copies per storefront, language, currency, device, WebP support and URL
• Product level purges from admin, vendor panel, import, API and orders
• Built-in warmer with a button and a nightly cron job
• Disk limit, damaged file detection and expiry when a promotion starts or ends
• X-Kv-Fpc header and an admin page that names every bypass reason; no core changes
