Anonymous HTML
Anonymous HTML is a generic, non-personalized version of a webpage that Speed Kit's backend creates and caches. To make a dynamic page cacheable, Speed Kit first fetches it in a way that simulates a brand-new visitor, without any user-specific cookies or login information. It then removes or hides all personalized content, such as shopping cart details or user account information. The resulting "anonymous" page is a clean, static shell that can be safely stored in the cache and served instantly to any user. The user's personalized data is then merged in on the client-side during the Dynamic Content Merging process.
