+Proxies are also frequently used in corporate networks, where
[FireWall

a TransparentProxy, this can happen without client configuration -- a sometimes problematic scheme also employed by
[ISP

-Many
[ISP
]s and organisations have a "transparent" caching proxy sitting between users and the rest of the InterNet. [Transparent
proxies|TransparentProxy] take all web traffic and redirect it through a proxy without any knowledge (or choice) of the users
. This is not usually a problem
, unless the users are trying
to measure performance of the network or the proxy

, 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
