Proxy Server

Overview#

Proxy Server 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 connects to the Proxy Server, requesting some resource, such as a file, connection, WEB page (URL), or other resource available from a different server and the Proxy Server evaluates the request and determines which server to connect the client.

Proxy Server is an Application Layer device which is an Observer and by definition a Man-In-The-Middle.

Proxy Server may not meet the strict definition of a Proxy as the End-User may not have Consented or provided Permission to the proxy.
