Modifying HTTP response headers with Transform Rules

Cloudflare has introduced a new feature called "HTTP Response Header Modification" within its Transform Rules for all plans. This functionality allows users to set or remove HTTP response headers as traffic passes through Cloudflare back to the client, enabling customers to enrich responses with information about request handling and debugging data. Previously, this was done using a Cloudflare Worker, but now it can be accomplished without writing any code. The new feature is especially useful for administrators who do not have complete control over their website's origin, such as those using SaaS providers or other third-party services.
