If the server ORB sends back a NEEDS_ADDRESSING_MODE  reply to the
client indicating the prefered
addressing disposition, then is the client ORB required to 'cache' the
prefered addressing
disposition per object reference, and use it for further requests to
the server ?

My understanding is that it is not required to cache anything, but it
would be a very good idea to do so to avoid requiring two round trip
transactions for every request.  It is best to cache on an object
reference by object reference basis, since there is no requirement
that
a server that replies with NEEDS_ADDRESSING_MODE for one object
reference will reply with the same mode for another object reference.
