 * If your client has a cache, call [close()][Cache.close]. Note that it is an error to create calls
 * against a cache that is closed, and doing so will cause the call to crash.
 *
 * ```java
 * client.cache().close();

 * OkHttp also uses daemon threads for HTTP/2 connections. These will exit automatically if they
 * remain idle.

 *  Fix: Improve recovery from failed routes.
 *  Fix: Accommodate tunneling proxies that close the connection after an auth
    challenge.
 *  Fix: Use the proxy authenticator when authenticating HTTP proxies. This
    regression was introduced in OkHttp 3.0.
 *  Fix: Fail fast if network interceptors transform the response body such that
    closing it doesn't also close the underlying stream. We had a bug where

    source.close()
