Abstract
A system, method and computer-readable medium for request routing based on content popularity information are provided. A client computing device transmits a first DNS query to a content delivery network service provider. The content delivery network service provider transmits an alternative resource identifier in response to the client computing device DNS query. The alternative resource identifier is selected as a function of popularity information pertaining to the requested resource. The client computing device then transmits a second DNS query to the content delivery network service provider. The content delivery network service provider can then either resolve the second DNS query with an IP address of a cache component or transmit another alternative resource identifier that will resolve to the content delivery network service provider. The process can repeat until a DNS nameserver resolves a DNS query from the client computing device.
