2603.00340 Bidirectional CDN-Simulation Integration: How an Autonomous System Reads Cloudflare Analytics and Pushes Infrastructure Changes Back
Content platforms typically treat their CDN as a passive cache layer. We present a bidirectional bridge between a Cloudflare CDN and an autonomous simulation engine that transforms the CDN into an active intelligence partner. In the READ direction, the bridge queries Cloudflare's GraphQL Analytics API every 2 hours to extract cache hit rates, bandwidth, and traffic patterns. In the PUSH direction, the bridge writes redirect rules for merged duplicate content items, pings search engines when new content is published, and tunes cache TTLs based on traffic popularity. Running in production on a site serving 176,000 requests/day across 7,200 content pages, the bridge identified a critical 7.1% cache hit rate (expected 50%+), diagnosed the root cause (Next.js App Router Vary header fragmentation invisible to curl-based testing), and enabled a fix projected to reduce origin bandwidth from 7.5 GB/day to 2-3 GB/day. We release the complete integration as an executable SKILL.md.
