DESCRIPTION

 

Java

Java is a programming language and development environment for

 

 

building downloadable Web components or Internet and intranet

 

 

business applications of all kinds.

 

 

 

 

Cookies

Cookies are files stored on a computer’s hard drive. Some web 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.
