CORBA23 — question re BiDir IIOP

Summary: I am having difficulty understanding the intended use of
BiDirPolicy::BidirectionalPolicy. This is described (in section 15.9) as
a POA policy to be passed to create_POA. That section also says that
both client and server must have the policy with the value of BOTH for
bi-directional communication to take place.

My problem is that I don"t see how this policy applies to a particular
POA. Once bi-directional communication has been negotiated on a
connection, it applies to any request targetted at the negotiated
address(es), regardless of what POA is the recipient of the request. Nor
is it tied to the lifetime of a particular POA. And, what is supposed to
happen if one POA has the policy with value BOTH, and another POA has
the policy with value NORMAL?
