#### Dispatcher

By default MockWebServer uses a queue to specify a series of responses. Use a
Dispatcher (`import okhttp3.mockwebserver.Dispatcher`) to handle requests using another policy. One natural policy is to
dispatch on the request path.
You can, for example, filter the request instead of using `server.enqueue()`.

### Java
```java
final Dispatcher dispatcher = new Dispatcher() {

  }

  override fun dispatcherQueueStart(
    call: Call,
    dispatcher: Dispatcher,
  ) {
    logWithTime("dispatcherQueueStart: queuedCallsCount=${dispatcher.queuedCallsCount()}")
  }

  override fun dispatcherQueueEnd(
    call: Call,
    dispatcher: Dispatcher,
  ) {
    logWithTime("dispatcherQueueEnd: queuedCallsCount=${dispatcher.queuedCallsCount()}")
  }

  override fun proxySelectStart(
    call: Call,

  var bodyLimit: Long by delegate::bodyLimit

  var serverSocketFactory: ServerSocketFactory? by delegate::serverSocketFactory

  var dispatcher: Dispatcher = QueueDispatcher()
    set(value) {
      field = value
      delegate.dispatcher = value.wrap()
    }

  val port: Int
    get() {
      before() // This implicitly starts the delegate.
      return delegate.port
    }

```kotlin
val call = client.newCall(request)

call.executeAsync().use { response ->
  withContext(Dispatchers.IO) {
    println(response.body?.string())
  }
}
```

This is implemented using `suspendCancellableCoroutine`
but uses the standard Dispatcher in OkHttp. This means
that by default Kotlin's Dispatchers are not used.

Cancellation if implemented sensibly in both directions.

    callStart()
    try {
      client.dispatcher.executed(this)
      return getResponseWithInterceptorChain()
    } finally {
      client.dispatcher.finished(this)
    }
  }

  override fun enqueue(responseCallback: Callback) {
    check(executed.compareAndSet(false, true)) { "Already Executed" }

    callStart()
    client.dispatcher.enqueue(AsyncCall(responseCallback))
  }

        CountDownLatch(0),
      )
    val dispatcher = RespondAfterCancelDispatcher(responseDequeuedLatches, requestCanceledLatches)
    dispatcher.enqueue(
      MockResponse
        .Builder()
        .bodyDelay(10, TimeUnit.SECONDS)
        .body("abc")
        .build(),
    )
    dispatcher.enqueue(
      MockResponse(body = "def"),
    )
    server.dispatcher = dispatcher
    client =
      client
