<p>A method of identifying a content server for serving content to a client in a network having a plurality of content servers capable of serving the content, the method comprising the steps of: receiving a request for domain name resolution, the request including a domain name data element; parsing the domain name data element to determine metadata related to the content service that sources the content; identifying a set of target servers that match the metadata, wherein the set of target servers has zero or more members; comparing the set of target servers to configuration parameters; pruning the set of target servers to eliminate target servers that do not match the configuration parameters; selecting a subset of one or more of the target servers that were not eliminated; and returning the subset as a response to the request for domain name resolution.</p> |
