Abstract
An announcement protocol may allow disparate, and previously incompatible, content delivery network caches to exchange information and cache content for one another. Announcement data may be stored by the respective caches, and used to determine whether a cache is able to service an incoming request. URL prefixes may be included in the announcements to identify the content, and longest-match lookups may be used to help determine a secondary option when a first cache determines that it lacks a requested content.
