.withQueryStringParameter("name", "peter"),
        )
        .respond(response().withBody("Peter the person!"))

      val client =
        OkHttpClient.Builder()
          .proxy(Proxy(SOCKS, InetSocketAddress(socks5Proxy.host, socks5Proxy.firstMappedPort)))
          .build()

      val response =
        client.newCall(
          Request("http://mockserver:1080/person?name=peter".toHttpUrl()),
        ).execute()

0.082 responseBodyStart
0.082 responseBodyEnd
0.083 connectionReleased
0.083 callEnd
```

Notice how no connect events are fired for the second call. It reused the connection from the first request for dramatically better performance.

### EventListener.Factory

 *  New: Include suppressed exceptions when all routes to a target service fail.


## Version 4.4.1

_2020-03-08_

 *  Fix: Don't reuse a connection on redirect if certs match but DNS does not. For better
    locality and performance OkHttp attempts to use the same pooled connection across redirects and
    follow-ups. It independently shares connections when the IP addresses and certificates match,

    originalSystemErr = System.err

    System.setOut(object : PrintStream(OutputStream.nullOutputStream()) {})
    System.setErr(object : PrintStream(OutputStream.nullOutputStream()) {})
  }

  fun uninstall() {
    originalSystemOut.let {
      System.setOut(it)
    }
    originalSystemErr.let {
      System.setErr(it)
    }
  }

#### ² HTTP/2 Cipher Suite Denylist

Cipher suites that are [discouraged for use][http2_denylist] with HTTP/2. OkHttp includes them because better suites are not commonly available. For example, none of the better cipher suites listed above shipped with Android 4.4 or Java 7.

[OkHttp30]: https://square.github.io/okhttp/changelog_3x/#version-300

        CipherSuite.TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305_SHA256,
        // Note that the following cipher suites are all on HTTP/2's bad cipher suites list. We'll
        // continue to include them until better suites are commonly available.
        CipherSuite.TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA,
        CipherSuite.TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA,
        CipherSuite.TLS_RSA_WITH_AES_128_GCM_SHA256,

 * if (forceCacheResponse.code() != 504) {
 *   // The resource was cached! Show it.
 * } else {
 *   // The resource was not cached.

 *
 * This technique works even better in situations where a stale response is better than no response.
 * To permit stale cached responses, use the `max-stale` directive with the maximum staleness in
 * seconds:
 *
 * ```java
 * Request request = new Request.Builder()
