Abstract
A method and apparatus for routing a data request in a content delivery network receives a Hypertext Protocol (HTTP) format client data request and redirects the client data request to a file transfer protocol such that the data is transferred to the client in the file transfer protocol rather than HTTP. The redirection from HTTP, for example, to FTP or some other fileserver protocol outsources the load on the content engines while taking advantage of well-established methods of data handling and security. In addition, the network can dynamically be provisioned to handle a data load. In one embodiment, WCCP and HTTP redirection methods are used separately or in combination to provide a distributed file system in which client's requests benefit from content routing prior to interacting (via a file protocol) with a file server.
