**Network Interceptors**

 * Able to operate on intermediate responses like redirects and retries.
 * Not invoked for cached responses that short-circuit the network.
 * Observe the data just as it will be transmitted over the network.
 * Access to the `Connection` that carries the request.

### Rewriting Requests

 * both.
 *
 * Applications may configure OkHttp with an authenticator for origin servers, or proxy servers,
 * or both.
 *
 * ## Authentication Retries
 *
 * If your authentication may be flaky and requires retries you should apply some policy
 * to limit the retries by the class of errors and number of attempts.  To get the number of
 * attempts to the current point use this function.
 *
 * ```java

### Events with Retries and Follow-Ups

OkHttp is resilient and can automatically recover from some connectivity failures. In this case, the `connectFailed()` event is not terminal and not followed by `callFailed()`. Event listeners will receive multiple events of the same type when retries are attempted.
