Pre-caching
Pre-caching is the first step in Speed Kit's Predictive Preloads feature. Once the Prediction Engine identifies a likely next page for a user, the Service Worker proactively fetches the HTML for that page in the background and stores it in the local Service Worker Cache on the user's device. This ensures the page's main document is instantly available if the user clicks the predicted link, eliminating Network Time.
