X-Android-Received-Millis is now OkHttp-Received-Millis
    X-Android-Response-Source is now OkHttp-Response-Source

    ```
 *  Improve cache invalidation for POST-like requests.
 *  Bring MockWebServer into OkHttp and teach it SPDY.

OkHttp DNS over HTTPS Implementation
====================================

This module is an implementation of [DNS over HTTPS][1] using OkHttp.

### Download

```kotlin
testImplementation("com.squareup.okhttp3:okhttp-dnsoverhttps:4.12.0")
```

### Usage

```
  val appCache = Cache(File("cacheDir", "okhttpcache"), 10 * 1024 * 1024)
  val bootstrapClient = OkHttpClient.Builder().cache(appCache).build()

OkHttp Coroutines
=================

Support for Kotlin clients using coroutines.

```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.

/**

 * server's hostname is sent to the proxy.
 *
 * Prior to sending any CONNECT request OkHttp always calls the proxy authenticator so that it may
 * prepare preemptive authentication. OkHttp will call [authenticate] with a fake `HTTP/1.1 407
 * Proxy Authentication Required` response that has a `Proxy-Authenticate: OkHttp-Preemptive`
 * challenge. The proxy authenticator may return either an authenticated request, or null to
 * connect without authentication.
