When reading response a header, use `header(name)` to return the _last_ occurrence of the named value. Usually this is also the only occurrence! If no value is present, `header(name)` will return null. To read all of a field's values as a list, use `headers(name)`.

To visit all headers, use the `Headers` class which supports access by index.
