assertEquals("/v1/chat/messages/2", request2.getPath());

  RecordedRequest request3 = server.takeRequest();
  assertEquals("/v1/chat/messages/3", request3.getPath());

  // Shut down the server. Instances cannot be reused.
  server.shutdown();
}
```

Your unit tests might move the `server` into a field so you can shut it down
from your test's `tearDown()`.

### API

#### MockResponse

    this because it only occurs if you have proxy configured and you share a connection pool among
    multiple `OkHttpClient` instances.

    This particularly-subtle bug was caused by us assigning each `OkHttpClient` instance its own
    `NullProxySelector` when an explicit proxy is configured. But we don't share connections when
    the proxy selectors are different. Ugh!

Applications that want to use the global SSL context with OkHttp should configure their
OkHttpClient instances with the following:

```java
okHttpClient.setSslSocketFactory(HttpsURLConnection.getDefaultSSLSocketFactory());
```

A simpler solution is to avoid the shared default SSL socket factory. Instead, if you
need to customize SSL, do so for your specific OkHttpClient instance only.

##### Synthetic headers have changed

Constructor injection is particularly concise in Kotlin:

```
class MyTest(
  private val server: MockWebServer
) {
  @Test
  fun test() {
    ...
  }
}
```

Multiple instances can be obtained by naming additional ones:

```
class MyTest(
  private val server: MockWebServer,
  @MockWebServerInstance("server2") private val server2: MockWebServer,
