Is the proxy server related to the cache server?

The barber shop is an intermediate device between the client and the server, used to process transactions between them without exposing each other.

A Cache server is a seed of a proxy server that stores content retrieved from the WAN locally so that other computers can be used without needing access to the WAN.

Squid is a good example of a proxy cache server that can be used as a standalone or combined proxy cache server.

Cache servers are often used in offices, where a large number of computers continuously request the same kind of data, such as software updates or database updates. When the client first requests an update, the cache server stores the update locally. The next time a customer requests the same update, they will provide the service locally, without going to the Internet.
