 * ## Cache Optimization
 *
 * To measure cache effectiveness, this class tracks three statistics:
 *
 *  * **[Request Count:][requestCount]** the number of HTTP requests issued since this cache was
 *    created.
 *  * **[Network Count:][networkCount]** the number of those requests that required network use.
 *  * **[Hit Count:][hitCount]** the number of those requests whose responses were served by the
 *    cache.

     ```

 *  Fix: Handle `HTTP/1.1 100 Continue` status lines, even on requests that did
    not send the `Expect: continue` request header.
 *  Fix: Do not count web sockets toward the dispatcher's per-host connection
    limit.
 *  Fix: Avoid using invalid HTTPS sessions. This prevents OkHttp from crashing
    with the error, `Unexpected TLS version: NONE`.
