160 Intel NetStructure Cache Appliance Administrator’s Guide
Parent cache
A cache higher up in a Cache hierarchy, to
which the Intel NetStructure Cache Appliance
can send requests.
POP
1. Point of Presence. Usually a city or location
to which a network can be connected, often
with dial up phone lines.
2. Post Office Protocol. The basic protocols for
addressing e-mail.
Proxy server
See Web proxy server.
Reverse proxy
A option that allows the Intel NetStructure
Cache Appliance to be configured as a web
server for convenient geographical distribution
of server content. Reverse proxy also off loads
static content service from servers building
dynamic content and provides a peak load
buffer or surge protector for web servers.
Sometimes referred to as Server acceleration.
Router
A device that handles the connection between 2
or more networks. Routers look at destination
addresses of the packets passing through them
and decide which route to send them on.
Server
The software engine resident in the appliance
that enables the appliance to cache objects.
Server acceleration
See Reverse proxy.
SNMP
Simple Network Management Protocol. A set
of standards used for communication with
devices connected to a TCP/IP network.
SNMP-compliant devices (agents) store
information about themselves in MIBs and
provide this information to SNMP Managers.
Soft Cluster
Multiple appliances that use an external
clustering device such as an L4 Switch or
router to handle load balancing and routing
responsibilities.
SSL
Secure Sockets Layer. A protocol that enables
encrypted, authenticated communications
across the Internet. Used mostly in
communications between web servers and web
browsers.
TCP
Transmission Control Protocol. An Internet
Standard transport layer protocol. TCP
provides reliable end-to-end communication by
using sequenced data sent by IP.
Transparent proxy caching
A configuration option that enables the Intel
NetStructure Cache Appliance to intercept and
respond to Internet requests without requiring
users to reconfigure their browser settings. It
does this by intercepting traffic destined for an
origin server and redirecting that traffic
through the cache.
URL
Uniform Resource Locator. The address that
defines the route to a file on the web or other
Internet facility.
