Super simple cache – Full Page Cache PrestaShop module

Super simple cache is a self-contained Full Page Cache (FPC) module for PrestaShop 9.2+ built around local compressed HTML storage—no external cache daemons, no special PHP extensions beyond standard zlib, and no core overrides.

Two operating modes: plug-and-play or Turbo Early

• Standard hook mode (default): works immediately after installation via PrestaShop dispatch hooks (~90–130 ms backend TTFB) without modifying any server file.
• Turbo Early mode (optional .user.ini): routes eligible anonymous requests through fpc_early.php via PHP auto_prepend_file before loading PrestaShop’s kernel or database (~10–25 ms backend TTFB), with built-in conflict detection against custom auto_prepend_file rules.

Strict e-commerce safety and proxy protection

• Never serves stale personal data: logged-in customers and visitors with items in their cart immediately switch to bypass mode via the HMAC-SHA256 signed context cookie ssc_fpc_ctx.
• Hard-excluded routes & checks: cart, checkout, customer account, authentication, search, contact, non-GET/HEAD requests, AJAX/JSON responses, non-200 pages, errors, and flash notifications always bypass safely.
• Marketing parameter normalization & headers: strips tracking params such as utm_*, fbclid, gclid, and msclkid before hashing cache keys, removes Set-Cookie on cache hits, and emits Cache-Control: no-store, no-cache, must-revalidate and X-Accel-Expires: 0 so proxies never serve guest cache over active sessions.

Automatic tag invalidation & Back Office diagnostics

• Instant content updates: edits to products, combinations, prices, stock quantities, categories, manufacturers, suppliers, carriers, CMS pages, or completed orders automatically invalidate only affected tags.
• CLI & Back Office tools: inspect live HIT/MISS/BYPASS ratios, disk usage limits (64–4096 MB), and generation counters under nalezny.cz > Super simple cache or run php bin/console supersimplecache:status and supersimplecache:clear [--tag=...].
• Compatibility & licensing: requires PrestaShop 9.2+ and PHP 8.2+; includes complete English, Czech, German, and French Back Office translations and a PDF user guide. Download free of charge (0.00 €) or select optional professional installation by a developer (49.00 €).
