Zephr User Guide

With the Zephr CDN

270 views 0

When using the Zephr CDN, you can run HTML feature rules in-browser or in the transformation layer of the CDN. This gives you flexibility when deciding how to integrate Zephr with your existing technology stack.

Running HTML feature rules in-browser with the CDN is less secure than using the transformation layer. This is due to the intrinsic risks associated with a JavaScript-based solution, such as the end user disabling JavaScript in their browser. To prevent circumvention of the JavaScript, Zephr recommends loading some or all content after the Zephr CDN has run.

For further information on running HTML features in the transformation layer of the CDN, see the HTML Features in the CDN Transformation Layer topic.

When using in-browser HTML features with the Zephr CDN, the CDN deploys a JavaScript library that is used to enact transformations in the browser.

Note: As the CDN deploys the JavaScript library, you cannot augment the decision data. Instead, you must use one or more alternative methods to include additional data in your browser-side decisions and end user journeys. For an example of augmenting data for your technical team, see the Augment Your Decision Data topic.

To use in-browser HTML feature rules with the CDN, you must do the following:

  • Configure your site to support browser-side HTML Features

    For further information on configuring the browser, see the Configure Your Site topic.

  • Add a feature to run client-side

    For further information on adding a feature to run client-side, see the Add a Browser-side HTML Feature topic.
