Technical Details

HTML Streaming is built using both Varnish Cache and LUA for powerful edge side includes. This allows section.io to cache the < head > of the HTML document for fast load time while pulling in the remainder of the content dynamically from the origin. Because content within the < body > tags is still fetched from origin, there is no risk of catching personalized content, and no need to make any changes to your source code.

In addition to the HTML Streaming feature you will have access to the latest versions of Varnish Cache for caching images and other content to speed up total page load time.
