/**
 * Protocols that OkHttp implements for [ALPN][ietf_alpn] selection.
 *
 * ## Protocol vs Scheme
 *
 * Despite its name, [java.net.URL.getProtocol] returns the [scheme][java.net.URI.getScheme] (http,
 * https, etc.) of the URL, not the protocol (http/1.1, spdy/3.1, etc.). OkHttp uses the word
 * *protocol* to identify how HTTP messages are framed.

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:5.3.0")
```

### Usage

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

ciphers.

When negotiating a connection to an HTTPS server, OkHttp needs to know which [TLS versions](https://square.github.io/okhttp/4.x/okhttp/okhttp3/-tls-version/) and [cipher suites](https://square.github.io/okhttp/4.x/okhttp/okhttp3/-cipher-suite/) to offer. A client that wants to maximize connectivity would include obsolete TLS versions and weak-by-design cipher suites. A strict client that wants to maximize security would be limited to only the latest TLS version and strongest cipher suites....

OkHttp Testing Support
======================

This module offers utilities and support for testing OkHttp itself. It's not intended for use by

    adapter. (thanks kwuollett)
 *  Add a media type class to OkHttp.
 *  Change custom header prefix:

    ```
    X-Android-Sent-Millis is now OkHttp-Sent-Millis
    X-Android-Received-Millis is now OkHttp-Received-Millis
    X-Android-Response-Source is now OkHttp-Response-Source
    X-Android-Selected-Transport is now OkHttp-Selected-Transport
    ```
 *  Improve cache invalidation for POST-like requests.
