Hierarchical Caching
Hierarchical Caching
Help | Content Gateway | Version 7.7.3
Websense Content Gateway can participate in
HTTP cache hierarchies
, in which requests not fulfilled in one cache can be routed to other regional caches, taking advantage of the contents and proximity of nearby caches.
A cache hierarchy consists of levels of caches that communicate with each other. Content Gateway supports several types of cache hierarchies. All cache hierarchies recognize the concept of
parent
and
child
. A parent cache is a cache higher up in the hierarchy, to which the proxy can forward requests. A child cache is a cache for which the proxy is a parent.
