Internet by Proxy

September 1, 2011



What is the fundamental purpose of a network proxy?

A) Creates a functional separation between users and the Internet

B) Increases bandwidth capacity of network communication

C) Routes network traffic between subnets

D) Encrypts traffic between users and a remote location

E) Makes fresh donuts in minutes!


The answer: A) Creates a functional separation between users and the Internet

A proxy is designed to limit direct access between users and Internet sites by terminating the user’s network connections on the proxy. The proxy then completes the request and sends the results to the end user. Since the proxy is always in the middle of the connection, there’s no possible way for users and Internet sites to directly communicate with each other.
