This class is in the `logging-interceptor` artifact.
 *  New: `Headers.Builder.addUnsafeNonAscii()` allows non-ASCII values to be added without an
    immediate exception.
 *  New: Headers can be redacted in `HttpLoggingInterceptor`.
 *  New: `Headers.Builder` now accepts dates.
 *  New: OkHttp now accepts `java.time.Duration` for timeouts on Java 8+ and Android 26+.

También puede ayudar a evitar confusiones para nuevos desarrolladores que vean un parámetro no usado en tu código y puedan pensar que es innecesario.

///

/// info | Información

En este ejemplo usamos headers personalizados inventados `X-Key` y `X-Token`.

    val recorded = server.takeRequest()
    assertThat(recorded.headers["Accept"]).isEqualTo("text/plain")
    assertThat(recorded.headers["Accept-Encoding"]).isEqualTo("gzip")
    assertThat(recorded.headers["Connection"]).isEqualTo("Keep-Alive")
    assertThat(recorded.headers["User-Agent"]!!).matches(Regex("okhttp/.*"))
  }

It might also help avoid confusion for new developers that see an unused parameter in your code and could think it's unnecessary.

///

/// info

In this example we use invented custom headers `X-Key` and `X-Token`.

But in real cases, when implementing security, you would get more benefits from using the integrated [Security utilities (the next chapter)](../security/index.md){.internal-link target=_blank}.
