proxy servers

Devices that process and filter all Internet Protocol (IP) packets that are directed to them and decide which protocols and services can be served out of their caches. Proxy servers tend to offer the greatest range of protocol and caching support since they cache Hypertext Transport Protocol (HTTP), Secure Hypertext Transport Protocol (HTTPS), File Transfer Protocol (FTP) and, in some cases, streaming content such as RealAudio and PointCast. Each workstation addresses the proxy server directly by setting specific parameters in each browser on each workstation.
