In case of topology:
A - P1 - P2 - P1 - B
is the idea to use in P1 context "in" when initial request comes to P1
from A or B and context "out" when initial request comes to P1 from P2?
Does context need to be set in replies too? If so, is reply context the
same as the corresponding request context?
And finally, does context need to be set for in-dialog requests/replies
the same way as for initial requests?
