+A program which forwards [HTTP], [HTTPS] and [FTP] requests, often but not necessarily
caching them. A caching proxy server serves requests from the [Cache] where possible, to reduce latency and bandwidth
.
-[Squid
] is
a widely used open source (free software) proxy server
.
+Proxies are also frequently used in corporate networks, where
[FireWall
]s often block access to [the outside world | InterNet], and only proxies are allowed to communicate with it. With
a TransparentProxy, this can happen without client configuration -- a sometimes problematic scheme also employed by [ISP]s to reduce the amount of traffic crossing their external links
.
-Some
[ISP
]s have "transparent
proxies"
, where all web traffic gets redirected
to a proxy without any knowledge (or choice) of the users.
-This
is because in New Zealand
, all international traffic incures data charges, so if the ISP can serve you a cached copy, they can save a couple of cents per megabyte
.
+Like
[WebServer
]s,
proxies often keep access logs. These logs are useful for debugging
, optimisation and maintenance tasks but can also be used
to show who
is doing what
, when and how much it's costing
