The above scenario is representative of most TLS set ups: the client uses certificates to validate
the identity of a server. The converse is also possible. Here we create a server that authenticates
a client and a client that authenticates a server.

```java
// Create the root for client and server to trust. We could also use different roots for each!
HeldCertificate rootCertificate = new HeldCertificate.Builder()

        .build(),
    )
    server.enqueue(
      MockResponse
        .Builder()
        .body("B")
        .build(),
    )
    assertThat(get(server.url("/a")).body.string()).isEqualTo("A")
    assertThat(get(server.url("/a")).body.string()).isEqualTo("A")
    assertThat(get(server.url("/b")).body.string()).isEqualTo("B")
    val c0e0 = server.takeRequest()

  }
