ensuring that the information sent arrives in one piece when it reaches
its destination. IP relates to the address of the client machine to which
data is being sent, as well as the address of the destination network.
Telnet A TCP/IP application protocol that provides a virtual terminal service,
letting a user log into another computer system and access a device as
if the user were connected directly to the device.
trace route This feature allows you to display the network hops from the
Webcache to a device on an IP network.
transparent cache The Webcache is connected to a Layer 4 device in your LAN which is
capable of Redirection. The Layer 4 switch (also known as a Layer 4
redirector or Web enabled switch) automatically redirects all Web
requests to the Webcache.
VLAN Virtual LAN. A group of location- and topology-independent devices
that communicate as if they are on the same physical LAN.

area. A WAN can cover a large geographic area, and may contain
several LANs within it.
URL Uniform Resource Locator. The address that defines the route to a file
on the web or other Internet facility.
UTC Coordinated Universal Time. This is the standard time common to every
place in the world. Formerly and still widely called Greenwich Mean
Time (GMT) and also World Time, UTC nominally reflects the mean
solar time along the Earth's prime meridian.
WAN port On the Webcache, the WAN port is an auto-negotiating
10BASE-T/100BASE-TX RJ-45 port which is used to connect the
Webcache to the network in an inline deployment environment.
WCCP Web Cache Communication Protocol. This protocol allows the
Webcache to be connected to one or more WCCP-enabled Cisco
routers in your network.
WELF WebTrends Extended Log Format. A proprietary Access Log format.
Using WELF, you can analyze Webcache access log files with WebTrends
Log Analyzer or Firewall Suite.
