    _PublicKey = elli_cookie:get(<<"key">>, Cookies),
    %% ... and do something with it

    %% create new cookie for domain www.example.com that expires in two weeks
    FizzCookie = elli_cookie:new(<<"fizz">>, <<"buzz">>,
                                 [elli_cookie:domain(<<"www.example.com">>),
                                  elli_cookie:expires({2, weeks})]),

    %% delete key cookie
    DeleteKeyCookie = elli_cookie:delete(<<"key">>),

    %% return response with cookies
    {ok, [DeleteKeyCookie, FizzCookie], <<"key deleted; fizz set">>}.
