How should we implement GrowthBook on sites utilizing CDNs like Akamai? When a user enters a URL, the CDN (Akamai) searches for a cached HTML version of the site. If it's available, this cached version is sent to the user. If the page is not in the cache, the CDN sends a request to our server for resources. This is the only moment when GrowthBook on our server can assign a variant of an AB test. However, this page with the assigned variant will be cached in Akamai for 1 hour for all users. How can we implement GrowthBook without compromising CDN functionalities?
