Learn how to configure your site to utilize HTML features with the Zephr CDN, including setting up CORS, injecting access details, and browser features script tags.

1. If you have not already done so, add a site as described in the Add a Site topic
2. When configuring your browser, as described in the Configure the Browser topic, configure the following options:

   • CORS Allowed Origins This must be configured if you want to use the Decision API. The Decision API is called by the JavaScript library served by the Zephr CDN. Enter a comma delimited list of all public base URLs from which the API is called.

   • Inject Access Details If you want to inject access details in the browser for use in your browser-side decisions, ensure that the Inject Access Details toggle is selected. The Inject Access Details toggle is selected by default.

   • Inject Browser Features Script Tags Ensure that the Inject Browser Features Script Tags toggle is selected. This injects a script tag that loads the JavaScript library for browser-side decisions. The Inject Browser Features Script Tags toggle is not selected by default.
