*    crashes the application on Android and prints a stacktrace on the JVM. (Crash reporting
 *    libraries may customize this behavior.)
 *
 * A good way to signal a failure is with a synthetic HTTP response:
 *
 * ```kotlin
 *   @Throws(IOException::class)
 *   override fun intercept(chain: Interceptor.Chain): Response {
 *     if (myConfig.isInvalid()) {

    }

    if (url.host == routeUrl.host) {
      return true // Host match. The URL is supported.
    }

    // We have a host mismatch. But if the certificate matches, we're still good.
    return !noCoalescedConnections && handshake != null && certificateSupportHost(url, handshake!!)
  }

  private fun certificateSupportHost(
    url: HttpUrl,
    handshake: Handshake,
  ): Boolean {

## Version 4.2.1

_2019-10-02_

 *  Fix: In 4.1.0 we introduced a performance regression that prevented connections from being
    pooled in certain situations. We have good test coverage for connection pooling but we missed
    this because it only occurs if you have proxy configured and you share a connection pool among
    multiple `OkHttpClient` instances.

So we have a dedicated thread for every socket that just reads frames and dispatches them.

  return if (address is InetSocketAddress) address.hostName else address.toString()
}

/**
 * Returns true if new reads and writes should be attempted on this.
 *
 * Unfortunately Java's networking APIs don't offer a good health check, so we go on our own by
 * attempting to read with a short timeout. If the fails immediately we know the socket is
 * unhealthy.
 *
 * @param source the source used to read bytes from the socket.
