*  New: Add `cacheHit`, `cacheMiss`, and `cacheConditionalHit()` events to `EventListener`. Use
    these in logs, metrics, and even test cases to confirm your cache headers are configured as
    expected.

 *  New: Constant string `okhttp3.VERSION`. This is a string like "4.5.0-RC1", "4.5.0", or
    "4.6.0-SNAPSHOT" indicating the version of OkHttp in the current runtime. Use this to include
    the OkHttp version in custom `User-Agent` headers.

      // If this response shouldn't have been stored, it should never be used as a response source.
      // This check should be redundant as long as the persistence store is well-behaved and the
      // rules are constant.
      if (!isCacheable(cacheResponse, request)) {
        return CacheStrategy(request, null)
      }

      val requestCaching = request.cacheControl
      if (requestCaching.noCache || hasConditions(request)) {

 *     .url("http://publicobject.com/helloworld.txt")
 *     .build();
 * ```
 *
 * The [CacheControl] class can configure request caching directives and parse response caching
 * directives. It even offers convenient constants [CacheControl.FORCE_NETWORK] and
 * [CacheControl.FORCE_CACHE] that address the use cases above.
