servers use them to track usage and provide service based on

 

ID.

 

 

Web Proxy

A server that acts as an intermediary between a user and the

 

Internet to provide security, administrative control, and

 

caching service. When a proxy server is located on the WAN it

 

is possible for LAN users to circumvent content filtering by

 

pointing to this proxy server.

field. Do not enter the complete URL of the site – that is, do

 

not include “http://”. All subdomains are allowed. For

 

example, entering “zyxel.com” also allows “www.zyxel.com”,

 

“partner.zyxel.com”, “press.zyxel.com”, and so on. You can

 

also enter just a top level domain. For example, enter .com to

 

allow all .com domains.

 

Use up to 127 characters (0-9a-z-). The casing does not

 

matter.
