And it’s the only way to preserve integrity of the connection. With
CONNECT, provided that the origin server presents a valid and matching
certificate and you check it, neither the proxy nor any other
man-in-the-middle between you and the proxy can spoof the origin
server, tamper with requests or responses, or sniff the traffic
between you and the origin. With “GET https://foo/bar”, all of the
above would be possible.
