[{$pagename}] is a [proxy] [Service] (a computer [server] or an [application]) that acts as an intermediary for [requests] from [clients] seeking [resources] from other servers. A [client|user-agent] connects to the [{$pagename}], requesting some [resource], such as a file, connection, [WEB] page ([URL]), or other [resource] available from a different server and the [{$pagename}] evaluates the [request] and determines which server to connect the [client|user-agent].
