MockResponse can be used to simulate a slow network. This is useful for
testing timeouts and interactive testing.

```java
response.throttleBody(1024, 1, TimeUnit.SECONDS);
```


#### RecordedRequest

Verify requests by their method, path, HTTP version, body, and headers.

```java

  private var failFastResponse: MockResponse? = null

  @Throws(InterruptedException::class)
  override fun dispatch(request: RecordedRequest): MockResponse {
    // To permit interactive/browser testing, ignore requests for favicons.
    val requestLine = request.requestLine
    if (requestLine == "GET /favicon.ico HTTP/1.1") {
      logger.info("served $requestLine")

    before the response starts. With duplex, request and response bodies are transmitted
    simultaneously. This can be used to implement interactive conversations within a single HTTP
    call.

    Create duplex calls by overriding the new `RequestBody.isDuplex()` method to return true.

 * [OkReplay](https://github.com/airbnb/okreplay): Record and replay OkHttp network interaction in your tests.
 * [okhttp-signpost](https://github.com/pakerfeldt/okhttp-signpost): OAuth signing with signpost and OkHttp.

   * may be sent after response headers or body bytes have been received.
   *
   * Though any call may be initiated as a duplex call, only web servers that are specially
   * designed for this nonstandard interaction will use it. As of 2019-01, the only widely-used
   * implementation of this pattern is [gRPC][grpc].
   *
   * Because the encoding of interleaved data is not well-defined for HTTP/1, duplex request

 *  Fix: Resurrect http/2 frame logging.
 *  Fix: Limit to 20 authorization attempts.

## Version 2.1.0

 *  New: Typesafe APIs for interacting with cipher suites and TLS versions.
 *  Fix: Don't crash when mixing authorization challenges with upload retries.
