 *  **Custom caches are no longer supported.** In OkHttp 1.x it was possible to
    define your own response cache with the `java.net.ResponseCache` and OkHttp's
    `OkResponseCache` interfaces. Both of these APIs have been dropped. In
    OkHttp 2 the built-in disk cache is the only supported response cache.
