Which proxy is also referred to as forced or intercepting because it redirects without client configuration?

• A. Non-transparent proxy
• B. Reverse proxy
• C. Caching engines
• D. Transparent (or forced or intercepting) proxy

Answer: (D)

Redirection of user traffic to a proxy without any client-side configuration is the hallmark of a transparent proxy. It sits in the network path and intercepts and forwards requests to the proxy automatically, often using gateway rules, NAT, or similar mechanisms. The client believes it’s connecting directly to the destination, while the proxy handles the traffic in the background. This is why it’s described as forced or intercepting—the redirection happens without any action required by the user or their device. This differs from a non-transparent proxy, which requires explicit configuration on the client (such as setting the browser to use the proxy). A reverse proxy operates on the server side, sitting in front of internal services to distribute or filter requests, not typically by transparently intercepting end-user traffic on the client side. Caching engines focus on storing and serving previously retrieved content to speed up access, rather than redirecting traffic transparently.
