### 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())
    .bootstrapDnsHosts(InetAddress.getByName("8.8.4.4"), InetAddress.getByName("8.8.8.8"))
    .build()

 * ```java
 * Request request = new Request.Builder()
 *     .cacheControl(new CacheControl.Builder().noCache().build())
 *     .url("http://publicobject.com/helloworld.txt")
 *     .build();
 * ```
 *
 * If it is only necessary to force a cached response to be validated by the server, use the more
 * efficient `max-age=0` directive instead:
 *
 * ```java
 * Request request = new Request.Builder()

            this.indexOption = builder;
            return this;
        }

        public RequestOptionCall<IndexRequestBuilder> indexOption() {
            return indexOption;
        }

        public DocMeta deleteOption(RequestOptionCall<DeleteRequestBuilder> builder) {
            this.deleteOption = builder;
            return this;
        }

    assertThat(httpUrl.toString()).isEqualTo("http://user@host/")
