+Many
[ISP]s and organisations
have a
"transparent" caching proxy sitting between users and the rest of the InterNet. Transparent proxies 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 is not WellBehaved. In NewZealand

ProxyServerNotes
+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.
+
+Proxies, like [WebServer]s often keep access logs. These logs are useful for debugging, optimisation and maintanance tasks but can also be used to show who is doing what, when and how much it's costing.
