ESB with DSS feature, how to use boxcarring?

I have installed DSS 3.2.2 feature on ESB 4.8.1 and I cannot use boxcarring, session cookie cannot be created after begin_boxcar is sent. I tried to switch transit transport to nhttp but failed.

Is it possible to use DSS feature with ESB instance? Is there some configuration I can fix to fix this?

Thank.
