#### 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() {

/**
 * Configuration implementation that delegates to another configuration instance.
 * Provides a wrapper mechanism for configuration objects with delegation pattern.
 *
 * @author mbechler
 */
public class DelegatingConfiguration implements Configuration {

    private final Configuration delegate;

    /**
     * Creates a delegating configuration that forwards calls to another configuration
     * @param delegate

  /**
   * Schedules the request to be executed at some point in the future.
   *
   * The [dispatcher][OkHttpClient.dispatcher] defines when the request will run: usually
   * immediately unless there are several other requests currently being executed.
   *
   * This client will later call back `responseCallback` with either an HTTP response or a failure
   * exception.
   *
