* ## Preemptive Authentication
 *
 * To make HTTPS calls using an HTTP proxy server OkHttp must first negotiate a connection with
 * the proxy. This proxy connection is called a "TLS Tunnel" and is specified by
 * [RFC 2817][1]. The HTTP CONNECT request that creates this tunnel connection is special: it
 * does not participate in any [interceptors][Interceptor] or [event listeners][EventListener]. It

    This is only relevant for duplex request bodies, because they are written concurrently when
    reading the response body.

 *  New: `MockResponse.inTunnel()` is a new `mockwebserver3` API to configure responses that are
    served while creating a proxy tunnel. This obsoletes both the `tunnelProxy` argument on
    `MockWebServer` and the `UPGRADE_TO_SSL_AT_END` socket option. (Only APIs on `mockwebserver3`

 4. If it's a new route, it connects by building either a direct socket connection, a TLS tunnel (for HTTPS over an HTTP proxy), or a direct TLS connection. It does TLS handshakes as necessary. This step may be retried for tunnel challenges and TLS handshake failures.
 5. It sends the HTTP request and reads the response.
