When I request www, I got random answers (10.1.1.1 or 10.1.1.2)
If I use the sortlist option, I always got the same answer.

My question : how can I have cyclic answers :
        request www --> reply 10.1.1.1
        request www --> reply 10.1.1.2
        request www --> reply 10.1.1.1
        request www --> reply 10.1.1.2

You can use BIND's RRSET Order for this,

I think that the order is global, not per-client. This way, two clients
asking repeatedly could get still the same answer.

Also note that intermediate servers may change the order (although they
should not).  I even encountered case where resolver library (libnss_lwres
IIRC) ordered the list and still provided in the same order.
