 *  Breaking: Reorder the parameters in the Cache constructor that was introduced in 5.0.0-alpha.3.

 *  New: `Request.Builder.cacheUrlOverride()` customizes the cache key used for a request. This can
    be used to make canonical URLs for the cache that omit insignificant query parameters or other
    irrelevant data.

    This feature may be used with `POST` requests to cache their responses. In such cases the

 * This cache limits the number of bytes that it will store on the filesystem. When the number of

 *  Fix: Don't drop repeated headers when validating cached responses. In our Kotlin upgrade we
    introduced a regression where we iterated the number of unique header names rather than then
    number of unique headers. If you're using OkHttp's response cache this may impact you.
