Abstract
A technique for optimizing delivery of specialized content files such as multimedia files in a computer network. A multimedia file cache is located at a point of presence, such as at an Internet Service Provider (ISP), gateway, or other place close to user connection points into the network. A redirection function intercepts media redirection file requests sent to or from the media server and rewrites such requests so that they point to the local media file cache.
