Dynamic Content Merging
Dynamic Content Merging is a Speed Kit feature that optimizes the delivery of pages with both static and dynamic content. It merges these two parts together in a smart way so that: (1) users get a fast static page render from the cache while (2) the dynamic content is being fetched fresh from the origin in parallel. This results in fast page loads even for pages with highly personalized or session-specific content.
