Media Flow Controller Overview
A caching structure that starts with RAM and incorporates a flexible hierarchy of cache
devices ensures that objects are placed and migrated across the hierarchies based on
dynamic load characteristics.
Cache tiers are implemented as an extendable framework, making it easy to add new types of
caching devices and origin storage. The caching system is agnostic to the delivery protocol,
allowing multiple delivery protocols to share the cached content. See

certain basic checks, such as URL validation, and parses the URL query string, and
header fields to identify the content and any associated policies. Media Flow Controller
