Odhiambo Washington"The sherminator" could have a point. Most people run proxies to filter out content like "blacklisted" sites, and not for caching. Its very likely why the given example, KU,
runs a proxy. In fact, many large setups do not cluster proxy services leading to poor surfing experiences for everyone....
anyways.... i second him. If you want to use a proxy to block some sites/content, having a local DNS server with blacklisted domains would be more efficient (no need for
proxy servers equals reduced capital and running costs)
To answer this thread's first question... transparent proxy. google it.
