This document discusses HTTP proxy servers. It defines a proxy server as a server that acts as an intermediary for requests from clients and acts as a client to the actual servers. An HTTP proxy server specifically handles HTTP requests. It can speed up browsing by caching frequently requested pages. It also anonymizes user requests and reduces load on the internet connection. The document then discusses the software Proxyfire as an example of a "distorting" HTTP proxy server and provides screenshots of its interface. It concludes by listing the hardware and software specifications of the system used.
