In particular, parse comma-separated lists where the elements of
the list may include quoted-strings. A quoted-string could
contain a comma. A non-quoted string could have quotes in the
middle. Quotes are removed automatically after parsing.
It basically works like :func:`parse_set_header` just that items
may appear multiple times and case sensitivity is preserved.
The return value is a standard :class:`list`:
>>> parse_list_header('token, "quoted value"')
['token', 'quoted value']

:func:`dump_header` function.

>>> type(d) is dict
True

If there is no value for a key it will be `None`:

{'key_without_value': None}

d dd |S ) a Create a Set-Cookie header without the ``Set-Cookie`` prefix.
The return value is usually restricted to ascii as the vast majority
of values are properly escaped, but that is no guarantee. It's
tunneled through latin1 as required by :pep:`3333`.
The return value is not ASCII safe if the key contains unicode
characters. This is technically against the specification but
happens in the wild. It's strongly recommended to not use
non-ASCII values for the keys.
:param max_age: should be a number of seconds, or `None` (default) if
the cookie should last only as long as the client's
browser session. Additionally `timedelta` objects
are accepted, too.
:param expires: should be a `datetime` object or unix timestamp.
:param path: limits the cookie to a given path, per default it will
span the whole domain.
:param domain: Use this if you want to set a cross-domain cookie. For
example, ``domain=".example.com"`` will set a cookie
that is readable by the domain ``www.example.com``,
``foo.example.com`` etc. Otherwise, a cookie will only
be readable by the domain that set it.
:param secure: The cookie will only be available via HTTPS
:param httponly: disallow JavaScript to access the cookie. This is an
extension to the cookie standard and probably not
supported by all browsers.
:param charset: the encoding for string values.
:param sync_expires: automatically set expires if max_age is defined
but expires not.
:param max_size: Warn if the final header value exceeds this size. The
default, 4093, should be safely `supported by most browsers
`_. Set to 0 to disable this check.
:param samesite: Limits the scope of the cookie such that it will
only be attached to requests if those requests are same-site.

The string ``'None'`` is accepted for ``samesite``.
