These are the primary classes involved with establishing, sharing, and terminating connections:

 * **RealConnectionPool** manages reuse of HTTP and HTTP/2 connections for reduced latency. Every OkHttpClient has one, and its lifetime spans the lifetime of the OkHttpClient.

first. Fast fallback gives IPv6 connections a 250 ms head start so IPv6 is preferred on networks
where it's available.

To opt-in, configure your `OkHttpClient.Builder`:


```
OkHttpClient client = new OkHttpClient.Builder()
    .fastFallback(true)
    .build();
```

 *  New: Change the build from Kotlin-JVM to Kotlin-multiplatform (which includes JVM). Both

```kotlin
testImplementation("com.squareup.okhttp3:okhttp-dnsoverhttps:5.1.0")
```

### Usage

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

  val dns = DnsOverHttps.Builder().client(bootstrapClient)
    .url("https://dns.google/dns-query".toHttpUrl())

    OkHttp 2 the built-in disk cache is the only supported response cache.

 *  **HttpResponseCache has been renamed to Cache.** Install it with
    `OkHttpClient.setCache(...)` instead of `OkHttpClient.setResponseCache(...)`.

 *  **OkAuthenticator has been replaced with Authenticator.** This new
    authenticator has access to the full incoming response and can respond with

Get a URL

This program downloads a URL and prints its contents as a string. [Full source][get_example].

```java
OkHttpClient client = new OkHttpClient();

String run(String url) throws IOException {
  Request request = new Request.Builder()
      .url(url)
      .build();

  try (Response response = client.newCall(request).execute()) {

    val part: MultipartBody.Part = multipartBody.part(0)

    val body: RequestBody = part.body()
