" summary

Device intelligence identifies a requesting handset from billions of requests per month using a compact device database (the WURFL data file) and drives an image pipeline called ImageEngine that resizes or serves cached variants so the browser gets the correctly sized asset on the first request. Built as an API and edge resizing service, it enables predictive resizing and real-time responses, cutting payloads and eliminating the need to ship multiple image variants or wait for lazy loading.
