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

Allow Java/ActiveX/Cookies/

When this box is selected, the ZyWALL will permit Java, ActiveX and

Web proxy to trusted web
