Summary
This post announces the General Availability (GA) of Cache Rules, a new feature built on the Rulesets Engine, which provides more granular control over caching configurations compared to the legacy Page Rules. It introduces new configuration options for Cache Rules, including Cache Reserve eligibility, timeout values, custom ports, and cache bypass logic. The post also details the technical challenges and scalability issues with the previous Page Rules implementation (regex-based matching) and explains how the Rulesets Engine's conditional evaluation improves performance and flexibility. It provides examples of using Cache Rules for content changing quickly and for slow origins, and announces the End-of-Life (EOL) process for Page Rules.
