Origin exposure, CDN bypass, edge comparisons

CDN Cache and DDoS: Why the Edge Only Absorbs the Traffic It Caches

A CDN only shields your origin from a flood for the traffic it caches. If your responses are not cacheable, the edge forwards the flood straight to your origin. How absorption works, what quietly breaks it, and how to test what your edge actually keeps.
