		1018	emptied. All other keys are hostnames or IP addresses pointing to
		1019	hash-references. The key for these inner hash references is the
		1020	server path for which this cookie is meant, and the values are again
		1021	hash-references. The keys of those hash-references is the cookie name, and
		1022	the value, you guessed it, is another hash-reference, this time with the
		1023	key-value pairs from the cookie, except for C<expires> and C<max-age>,
