The Cache 360 Ultra is a downloadable module specifically designed for PrestaShop, catering to both merchants and technical teams managing online retail platforms. This module performs a thorough audit of the shop and its hosting environment to ensure compatibility and facilitates controlled testing prior to implementing any cache modifications. With three distinct cache modes tailored to various hosting configurations, it provides tools for prewarming public pages and swiftly invalidating affected pages following updates to the product catalog. Additionally, visitors who are logged in, have items in their cart, or navigate to checkout and account pages are exempt from public-page caching. The features also encompass image and delivery diagnostics, complete with reversible controls that allow for testing different cache settings. Unlike hosted SaaS options, this module is directly installed on the merchant’s PrestaShop store, making it a more integrated solution. Upon purchase, customers receive comprehensive documentation along with 12 months of updates and dedicated technical support, ensuring they have the resources needed for effective implementation and ongoing assistance. Ultimately, Cache 360 Ultra enhances the efficiency and functionality of online stores while providing a user-friendly experience for both merchants and customers.
