Definition: proxy: In communications, a proxy is something
that acts as a server, but when given requests from
clients, acts itself as a client to the real servers.
Analogy: Consider talking to somebody who speaks a foreign
language through a translator. You talk to the translator,
who receives your statements, then regenerates something
else completely to the other end. The translator serves as
your proxy. Key point: The communication terminates at the
proxy. In other words, the proxy doesn't forward data so
much as it tears it completely apart. For example, an HTTP
proxy doesn't forward every request sent through it.
Instead, it first examines if it already has the requested
web page in its cache. If so, then it returns that page
without sending another request to the destination server.
Because proxies completely terminate the communication
channel, they are considered a more secure firewall
technology than packet filters, because they dramatically
increase the isolation between the networks. Key point: You
will occasionally be scanned for proxies. ISPs scan their
users for proxies. Hackers scan the Internet looking for
proxies they can anonymize their connections with. Certain
servers (like IRC servers) scan clients for proxies in
order to prevent anonymous connections. Several websites
maintain lists of such
