Forward proxies are proxies in which the client server names the target server to connect to.[2] Forward proxies are able to retrieve from a wide range of sources (in most cases anywhere on the Internet). The terms "forward proxy" and "forwarding proxy" are a general description of behavior (forwarding traffic) and thus ambiguous.
