In one example, a CDN exchange includes a communication module to receive first network prefixes and first content identifiers from a first secondary content delivery network and to receive second network prefixes and second content identifiers from a second secondary content delivery network. A request router of the CDN exchange redirects the content request to the first secondary content delivery network or to the second secondary content delivery network according to a network address of the end user device and a content identifier for the content request."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Content delivery network referral","description":"In general, techniques are described for managing content request referrals by keying content requests to a composite key data structure that maps end-user address prefixes and content identifiers to ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9756124","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
