This is a free proxy available as open-source software made specifically for UNIX-based systems. It is a web proxy cache available at www.squid-cache.org. It is used by numerous small and large businesses, and even home users.

If a small program is necessary, then TinyProxy may be the solution. Its distribution is on the GNU GPL license so this HTTP proxy can provide a small but effective solution for businesses with POSIX systems. It is remarkably easy to use and gives the user the ability to allocate the HTTP headers that are allowed, and prevent certain information from being sent to the server. It is available at http://www.tinyproxy.sourceforge.net. It is quite useful based on the fact that it can be easily modified to suit your business needs.
