Question

A media company distributes premium video through a global content-distribution network (CDN). Analytics reveal that paying subscribers' video URLs are being shared and embedded on third-party sites, allowing non-subscribers to stream content for free (hotlinking). The origin server load is minimal because the CDN caches everything, but revenue is leaking. Which CDN-layer control most directly stops unauthorized reuse of the content URLs?

Accepted Answer

Enable signed/tokenized URLs with short expiration and client-IP or referrer binding at the CDN edge

Answer

Force TLS 1.3 on all edge connections and disable older cipher suites

Answer

Increase the CDN cache TTL so content is served faster to legitimate users

Answer

Deploy a rate-limiting rule on the origin server to throttle excessive requests
