Thank you all for you answers!

Still didn't find a handy solution.

There was the idea of including one iFrame per each other domain to store cookies for all domains at the same time with the same 
session parameters.
(See here http://stackoverflow.com/questions/16345398/) - I didn't check this approach yet.
