📝 WalkthroughWalkthroughLa modifica introduce la cache full-page LiteSpeed opzionale, il purge a tag, il bypass lookup-time e una CSP basata su hash. Le pagine condivise ricevono disponibilità live tramite un endpoint JSON batch. Le impostazioni admin, le sessioni instradate e i test coprono il nuovo flusso. ChangesCache LiteSpeed e dati live
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟠 High · up to This PR moves anonymous pages behind a shared full-page cache, but incomplete cache purges or disabled-cache configurations can leave stale pages available after privacy or access settings change. Availability controls can also remain disabled or show misleading states when live updates fail, and the purge secret may be transmitted without encryption. The PR is not merge-ready until these security and correctness issues are addressed. Sequence Diagram(s)sequenceDiagram

Inline comments:
In `@app/Controllers/FrontendController.php`:
- Around line 542-569: Cache the live availability aggregate in the withStats
block using the existing rememberCatalogValue() mechanism, with a short TTL
suitable for loan-movement freshness. Preserve the current total_books and
available_books payload, exception logging, and 503 response behavior when the
cached computation fails.
In `@app/Controllers/SettingsController.php`:
- Around line 911-913: Update the redirect in the LiteSpeed failure branch of
SettingsController to use the existing route helper, such as route_path() or
RouteTranslator::route(), with the appropriate settings route key instead of the
hardcoded /admin/settings path; preserve the advanced-tab query parameter.
In `@app/Middleware/LiteSpeedCacheMiddleware.php`:
- Around line 45-53: Update the LiteSpeedCacheMiddleware branch immediately
after LiteSpeedCache::enabled() to return the response with
X-LiteSpeed-Cache-Control set to no-cache when caching is disabled, while
preserving removal of the marker header and the existing isCacheable handling.
In `@app/Support/ConfigStore.php`:
- Around line 139-146: Aggiorna ConfigStore::loadDatabaseSettings() per mappare
e caricare la categoria cache dal repository, incluse litespeed_enabled,
litespeed_home_ttl, litespeed_catalog_ttl e litespeed_book_ttl, così i valori
salvati da SettingsController persistano e siano disponibili a LiteSpeedCache.
In `@app/Support/LiteSpeedCache.php`:
- Around line 252-256: Update isHttpUrl() and the URL validation used by
dispatchCliPurge() so HTTP is permitted only for loopback hosts, while all
remote destinations require HTTPS; preserve the existing purge behavior and
prevent X-Pinakes-Purge-Secret from being sent to any remote HTTP endpoint.
In `@app/Support/SessionPolicy.php`:
- Line 46: Replace the hardcoded /api/edge/availability entry in
SESSIONLESS_ROUTE_KEYS with a defined route key resolved through
RouteTranslator::route('key'); add the corresponding route-key definition and
preserve the existing sessionless behavior.
In `@app/Views/frontend/book-detail.php`:
- Around line 1928-1934: Provide a neutral pending fallback for every edge-cache
availability placeholder and keep pending states consistent: in
app/Views/frontend/book-detail.php:1928-1934 use “Verifica disponibilità”
instead of an empty label and retain availability-pending; in
app/Views/frontend/book-detail.php:2485-2493 use the same fallback in
book-status-inline and the count value; in
app/Views/frontend/book-detail.php:2601-2610 replace available-badge with the
pending class; in app/Views/frontend/catalog-grid.php:11-18 and
app/Views/frontend/home-books-grid.php:11-18 replace status-unavailable with the
pending class and populate data-live-label with the neutral fallback.
- Around line 1954-1956: Update the btn-request-loan rendering so edge-cache
mode emits a usable server-side fallback label and enabled button state instead
of an empty disabled control. Preserve the live-availability data attributes and
client-side updates, but ensure the fallback remains actionable when JavaScript
is unavailable or the availability request fails; do not rely on pointer-events
to override disabled.
In `@app/Views/frontend/home-sections/hero.php`:
- Around line 79-82: Update the available-books span in the hero statistics
markup so data-server-rendered="1" is emitted only when heroStatsServerRendered
is true and edgeCacheEnabled is false. When edge caching is enabled, keep the
span empty and render the existing loading spinner as its pending state,
allowing loadStats() to use the fallback when live hydration does not complete.
In `@locale/da_DK.json`:
- Line 6982: Remove the duplicate locale entries for “Impossibile elaborare
l'immagine.”, “30 minuti”, “1 ora”, and “2 ore” in the Danish translation
resource, retaining exactly one entry for each key and preserving its existing
translation.
Apply the same fix in `@locale/de_DE.json` around lines 6996 - 7002: Copre le
ridefinizioni delle chiavi di durata nel catalogo tedesco.
Apply the same fix in `@locale/fr_FR.json` around lines 6996 - 7002: Copre le
ridefinizioni delle chiavi di durata nel catalogo francese.
Apply the same fix in `@locale/it_IT.json` around lines 6991 - 7002: Copre le
ridefinizioni delle chiavi di durata nel catalogo italiano.
Apply the same fix in `@locale/it_IT.json` at line 4008: Copre il rilievo
duplicato relativo ai cataloghi danese, tedesco e francese oltre a quello
italiano.
In `@public/assets/js/live-availability.js`:
- Around line 64-82: Update hydrate() to maintain a generation counter for each
invocation and capture the invocation’s generation before awaiting its payloads.
In the payload-resolution callback, apply book and stat updates, including
updateElement and element.remove, only when that generation is still the latest;
ignore obsolete responses entirely.

… table #392 registered admin.settings as a translatable route key (RouteTranslator fallbacks + all five routes_*.json) and redirected the advanced-settings save via route_path('admin.settings'). Project rule 4 (#145) reserves admin routes as English literals: route_path resolves against the session locale, and the admin route-editor UI exposes every key as a free-text input with no admin.* guard, so localizing admin.settings to a non-English path makes the post-save redirect resolve to a path the Slim router never registered (the GET route is the literal /admin/settings) — a 404 for that admin. Redirect both updateAdvancedSettings paths via url('/admin/settings') — the rule-4 sanctioned admin helper, which also preserves the base-path awareness the original review asked for (route_path never provided it, being i18n only). Drop the admin.settings key from RouteTranslator and routes_*.json. Updates the guard test.
