#### 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
final Dispatcher dispatcher = new Dispatcher() {

    @Override

import mockwebserver3.SocketPolicy.StallSocketAtStart

internal fun Dispatcher.wrap(): mockwebserver3.Dispatcher {
  if (this is QueueDispatcher) return this.delegate

  val delegate = this
  return object : mockwebserver3.Dispatcher() {
    override fun dispatch(request: mockwebserver3.RecordedRequest): mockwebserver3.MockResponse {
      return delegate.dispatch(request.unwrap()).wrap()
    }

import java.util.concurrent.LinkedBlockingQueue
import java.util.logging.Logger
import okhttp3.ExperimentalOkHttpApi

/**
 * Default dispatcher that processes a script of responses. Populate the script by calling [enqueueResponse].
 */
@ExperimentalOkHttpApi
open class QueueDispatcher : Dispatcher() {
  protected val responseQueue: BlockingQueue<MockResponse> = LinkedBlockingQueue()
  private var failFastResponse: MockResponse? = null
