### `scope` { #scope }

The spec also says that the client can send another form field "`scope`".

The form field name is `scope` (in singular), but it is actually a long string with "scopes" separated by spaces.

Each "scope" is just a string (without spaces).

They are normally used to declare specific security permissions, for example:

    if (entries.isEmpty()) {
      return emptyMultiset(comparator);
    }
    ImmutableList.Builder<E> elementsBuilder = new ImmutableList.Builder<>(entries.size());
    long[] cumulativeCounts = new long[entries.size() + 1];
    int i = 0;
    for (Entry<E> entry : entries) {
      elementsBuilder.add(entry.getElement());
      cumulativeCounts[i + 1] = cumulativeCounts[i] + entry.getCount();
      i++;

      stream.sink.flush()
      responseSent.countDown()
    }
  }

  fun exhaustResponse() =
    apply {
      actions += { stream -> stream.sink.close() }
    }

  fun sleep(
    duration: Long,
    unit: TimeUnit,
  ) = apply {
    actions += { Thread.sleep(unit.toMillis(duration)) }
  }

  override fun handle(socket: Socket) {
    val task = serviceSocketTask(socket.asBufferedSocket())

  private static void assertChecksum(ImmutableSupplier<Checksum> supplier, String input) {
    byte[] bytes = HashTestUtils.ascii(input);

    Checksum checksum = supplier.get();
    checksum.update(bytes, 0, bytes.length);
    long value = checksum.getValue();

    String toString = "name";
    HashFunction func = new ChecksumHashFunction(supplier, 32, toString);
    assertThat(func.toString()).isEqualTo(toString);
