instant

Behavior name: Akamai Instant (Prefetching)

The Instant feature allows you to prefetch content to the edge cache by adding link relation attributes to markup. For example:

xml <a href="page2.html" rel="Akamai-prefetch">Page 2</a>

Default link relation values are prefetch and Akamai-prefetch. Applies only to HTML elements that may specify an external file: <a>, <base>, <img>, <script>, <input>, <link>, <table>, <td>, or <th>. For the latter three, some legacy browsers support a nonstandard background image attribute.

This behavior provides an alternative to the prefetch and prefetchable behaviors, which allow you to configure more general prefetching behavior outside of markup.
