How did John Mosquera utilize Cloudflare Workers to implement server-side A/B testing for the client's web applications?

John likely leveraged Cloudflare Workers to implement server-side A/B testing without burdening the origin servers. He would have created a Worker script that intercepts incoming requests and, based on predefined criteria (such as user cookies, geolocation, or random sampling), dynamically serves different versions of content. This could involve modifying HTML on the fly, changing API responses, or redirecting to different backend services. John might have implemented a system to store and update test configurations without redeploying the Worker. He would have also set up logging within the Worker to track which version was served to each user, enabling analysis of test results. Additionally, John could have integrated this system with analytics tools to measure the performance of each variant. John implemented server-side A/B testing using Cloudflare Workers by creating scripts that dynamically serve different content versions based on defined criteria, setting up configuration management, implementing logging for test tracking, and integrating with analytics tools, enabling efficient experimentation without impacting origin server performance.
