Using OkHttp is easy. Its request/response API is designed with fluent builders and immutability. It
supports both synchronous blocking calls and async calls with callbacks.

A well behaved user agent
-------------------------

OkHttp follows modern HTTP specifications such as

* HTTP Semantics - [RFC 9110](https://datatracker.ietf.org/doc/html/rfc9110)

    @Size(max = 1000)

                        "x_tag": [],
                        "accept": "*/*",
                        "accept-encoding": "gzip, deflate",
                        "connection": "keep-alive",
                        "user-agent": "testclient",
                        "save-data": "true",
                        "if-modified-since": "yesterday",
                        "x-tag": ["one", "two"],
                    },
                }
            ]

`Header` має додатковий функціонал порівняно з `Path`, `Query` та `Cookie`.

Більшість стандартних заголовків розділяються символом «дефіс», також відомим як «мінус» (`-`).

Але змінна, така як `user-agent`, є недійсною в Python.

Тому, за замовчуванням, `Header` автоматично перетворює символи підкреслення (`_`) на дефіси (`-`) для отримання та документування заголовків.

    val cookies = cookieJar.loadForRequest(userRequest.url)
    if (cookies.isNotEmpty()) {
      requestBuilder.header("Cookie", cookieHeader(cookies))
    }

    if (userRequest.header("User-Agent") == null) {
      requestBuilder.header("User-Agent", USER_AGENT)
    }

    val networkRequest = requestBuilder.build()
    val networkResponse = chain.proceed(networkRequest)

    assertThat(recorded.headers["Accept"]).isEqualTo("text/plain")
    assertThat(recorded.headers["Accept-Encoding"]).isEqualTo("gzip")
    assertThat(recorded.headers["Connection"]).isNull()
    assertThat(recorded.headers["User-Agent"]!!).matches(Regex("Jetty/.*"))
  }
