G.19 proxy
A secure server through which internal clients connect to the internet. A service that allows clients
to make indirect network connections to other networks, for example, an HTTP proxy for use by
hosts with no direct connection to the internet. A client connects to the proxy server, then requests
a connection, file, or other resource available on a different server. The proxy provides the resource
either by connecting to the specified server or by serving it from a cache. In some cases, the
proxy may alter the client’s request or the server’s response for various purposes. A proxy server
can also serve as a firewall.
