How it works 1. Client request file 2. If file in cache CF return file Nearest Edge Location a. If file not in cache, CF request to origin b. Origin returns file, status 200, cached in CF 1. Client request file 2. If file in cache CF return file Nearest Edge Location a. If file in cache but expired, CF request to origin b. Origin returns 304, CF keeps file in cache Routing based on low latency/price class Routing based on low latency/price class Condition GET Wednesday, 7 August 13
