/// info | Información

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

    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+.
