Zusammenfassung:A method and system for delivering content with a content delivery network (CDN) to a user computer is disclosed. After an initial request to a point of presence (POP) of the CDN for the location of the content object, an Anycast Internet protocol (IP) address is assigned. The user computer requests the content object which may find its way to the same or a different POP depending on what is closer in Internet terms. The request returns a POP-specific IP in a redirect such that the request resolves to the POP referenced in the immediately preceding sentence. One or more edge servers deliver the content object to the user computer.
