"The client, in the re-send of the request, in order to be successful, will have to present credentials for the realm shown in the Proxy-Authenticate or WWW-Authenticate header." The UAC never has to determine the actual identity of the proxy. It does have to determine the realm that the proxy is demanding credentials for, but that is shown in the *-Authenticate header.
