With SNI, the assumption "same IP and port, same TLS peer" no longer
holds true. Two backend URLs, though served from the same IP:port, might
have very different characteristics (one using an RSA cert, the other
ECDSA e.g., and distinct supported cipher suites). I.e., you're really
talking to two completely different peers in this case.
