Cloudflare has introduced a new feature called Origin Range Requests to improve the efficiency of caching large files. This feature addresses issues with their previous range caching method, which often led to excessive data transfer and latency. The new implementation reportedly reduces the time to first byte by 50% and decreases tiered cache traffic by 6%. This change is now available to all Cloudflare users as a self-service feature through Cache Rules. The previous method required static zone configuration and had limitations with concurrent requests, causing delays for users accessing large files. The update aims to enhance user experience and optimize resource usage across Cloudflare's CDN. No vulnerabilities or exploitation concerns are reported in relation to this update.
