summary

Uses NGINX + Ceph RGW as an edge CDN by adding two RGW endpoints: an authentication API and a cache API. Implementation uses OpenResty (NGINX + Lua) to wrap AWSv4-signed range requests, override ranges for read‑ahead, and store objects on NVMe. Lab tests show almost 2x throughput versus RGW alone; a 50 MB object takes ~29 s cold and much less once cached. Notes: auth calls add overhead on tiny objects and cache is eventually consistent.
