# Request routing optimization for CDN and MediaTailor integrations
<a name="cdn-optimize-routing"></a>

Implement these routing optimizations for all AWS Elemental MediaTailor CDN integrations:
+ Create separate cache behaviors for manifest and segment requests
+ Configure origin request policies to control header forwarding
+ Set up proper error handling and failover mechanisms
+ Implement origin shields if available in your CDN to reduce origin load
+ Implement request collapsing at the CDN level to efficiently handle concurrent requests
