Cache 360 Ultra is a downloadable PrestaShop module for merchants and technical teams responsible for online stores. It audits a shop and its hosting environment, checks compatibility, and supports controlled testing before cache changes are applied. Three cache modes address different hosting setups, with tools for prewarming public pages and invalidating affected pages after catalogue changes. Visitors who are signed in, have an active cart, or access checkout and account pages bypass public-page caching. The module also includes image and delivery diagnostics, along with reversible controls for testing cache configurations. It is installed on the merchant’s PrestaShop store rather than used as a hosted SaaS subscription. A purchase includes documentation, 12 months of updates and technical support.
