From: "steffen.wilberg%web.de" Many organizations block access from the Internet to their networks.
- This prevents outside parties from gaining access to sensitive
- information. The protection is called a firewall. If your organization has a firewall, the browser may need to go through
- a proxy server before connecting you to the Internet. The proxy server
- prevents outsiders from breaking into your organization's private
- network. Your organization or internet service provider may offer or require you
+ to use a proxy. A proxy acts as an intermediary between your computer and
+ the Internet. It intercepts all requests to the Internet to see if it can
+ fulfill the request using its cache. Proxies are used to improve
+ performance, filter requests, and hide your computer from the Internet to
+ improve security. Proxies are often part of a corporate firewall.
