Manual Server Push & Ion

With the HTTP/2 behavior included in your Ion property, you can add this behavior to load a specified set of objects into the client browser’s cache. The server sends multiple parallel responses for a single client request. An average web page requires multiple resources, such as JavaScript, CSS, and images. References to these items are in the HTML pages the server produces. Manual Server Push allows the server to send the most important items immediately.
