Content distribution network server management system architecture

摘要

Multi-proxy caches are located at the edge of a defined network domain to support multiple network clients. A portion of a multi-proxy cache is operated as a reverse proxy cache, providing access to predesignated content selectively distributed from one or more origin servers. Portions of the reverse proxy can be logically designated to cache pre-fetched content, while other portions can be designated to cache content retrieved on an as-requested basis. The reverse proxy caches can be limited to selectively caching content specified subject to a defined scope of content from one or more defined origin servers. Storage of content to the cache is subject to cache content replacement policies differentially specified for different classes of predesignated content. Remaining portions of the multi-proxy caches permit caching of forward proxy requested content.
