Adaptive Acceleration

Adaptive Acceleration uses real user monitoring (RUM) navigation and timing data to intelligently cache content that viewers will likely need ahead of when it’s actually needed. This approach shortens delivery times, reduces the load on the network, and renders web pages faster.

Adaptive Acceleration uses highly effective techniques that:

  • push resources and domains to the browser and pre-connects ahead of time
  • pre-position content to improve HTML page load performance
  • preload fonts to improve page load performance
  • augment responses to HTML page requests by unintrusively sending content to the browser as needed

As long as your site’s configuration is secure, and you have both HTTP/2 and a beacon source enabled on the same property, you can enable (turn on) the following Adaptive Acceleration default settings

  • Automatic Server Push Allows your web server to send multiple responses, in parallel, for a single client request. An average web page requires multiple items, such as javascript, CSS, and images. References to these items are in the HTML pages the edge server produces. Automatic server push allows the your web server to send the most important items immediately.
  • Automatic Preconnect Allows browsers to anticipate what connections your site needs and establishes those connection ahead of time, but it does not load or request anything
  • Automatic Font Preload Allows browsers to preload the fonts it will need before it fetches and processes other resources.

You can keep these settings off if you want—for example, if you need to reduce load on the origin server for any reason. When Automatic Server Push is off, HTTP/2 is not required.

Advanced Settings (Property Manager only)

Adaptive Acceleration includes advanced settings that allow you to set up your own criteria for the items pushed to your visitors’ browser, and to specify the domains for which you do not want to use preconnect. To use these advanced settings, convert your OCA property to Property Manager.

For more information on advanced settings, see Property Manager help.
