HTTP-Cache: What
Use of Proxy Server
Previously fetched WWW objects are
stored in Proxy Server
Proxy Server gives cached WWW
object instead of fetches it from WWW server
HTTP-Cache: Why
Web is the most popular application
on The Net
Web traffic in byte is about 40%
WAN link get congested
HTTP-Cache: Facts
HTTP-Cache reduces WAN traffic
Cache Hierarchy
Cache-Server mesh
Collaborates using “parent-sibling”
relationship
Sibling: fetches WWW-object only if it
is found in local cache
Parent: always fetches requested
