Wont the proxy server always do a redirection, even if the destination IP is the original webserver? A debug should reveal a 301 move, especially if the request is the server IP address. I think the key is the browser configuration which is redirected to proxy. I think answer is B, though the question was meant to confuse readers.

Selected Answer: C
For the transparent proxy method, the request contains the destination IP address of the web server and the proxy transparently intercepts the client request (either by being in-line or by traffic steering). There is no client configuration and Panorama is optional. Transparent proxy requires a loopback interface, User-ID configuration in the proxy zone, and specific Destination NAT (DNAT) rules. Transparent proxy does not support X-Authenticated Users (XAU) or Web Cache Communications Protocol (WCCP). https://docs.paloaltonetworks.com/pan-os/11-0/pan-os-new-features/networking-features/web-proxy

Bros, at first (and I remember I got this question on the exam, took it on August 13th 2024 - 2nd failure). In explicit proxy, you would send the traffic explicitly to the web proxy, this means, that you'd be aware of the web proxy connection. However, this question states that the petition is sent to the web server (not proxy). The web browser transparently sends the petition to the proxy and there you go.
