Dynamic Blocks
Dynamic Blocks are specific, designated areas within a webpage that contain personalized or frequently changing content. Speed Kit can be configured to treat these blocks differently from the rest of the page. While the main page structure is served from the cache, these blocks are always fetched live from your origin server to ensure the data (e.g., a real-time stock counter or a personalized user greeting) is always up-to-date.
