Thanks for your answer. Unfortunately this is not sufficient, as the library already provides a cookie jar : 
'_msg' => 'Forbidden',
'_rc' => '403',
'_headers' => bless( {
    'connection' => 'close',
    'client-ssl-cipher' => 'ECDHE-RSA-AES128-GCM-SHA256',
    'set-cookie' => 'JSESSIONID=node0k6eor4wib9o5cbccpa3lkm5l220939.no
+de0;Path=/;HttpOnly',
    'date' => 'Thu, 14 Mar 2019 12:28:03 GMT',
    '::std_case' => {
        'client-ssl-cert-issuer' => 'Client-SSL-Cert-Issuer',
        'x-application-context' => 'X-Application-Context',
        'client-ssl-socket-class' => 'Client-SSL-Socket-Class',
        'client-ssl-cert-subject' => 'Client-SSL-Cert-Subject',
        'client-peer' => 'Client-Peer',
        'set-cookie' => 'Set-Cookie',
        'client-ssl-cipher' => 'Client-SSL-Cipher',
        'client-date' => 'Client-Date',
        'client-response-num' => 'Client-Response-Num'
    },
    'client-response-num' => 1,
    'client-date' => 'Thu, 14 Mar 2019 12:29:19 GMT',
    'client-ssl-socket-class' => 'IO::Socket::SSL',
    'client-peer' => 'XXSnipped at boss requestXX',
    'client-ssl-cert-subject' => 'XXSnipped at boss requestXX',
    'expires' => 'Thu, 01 Jan 1970 00:00:00 GMT',
