Yes, IIOP connections are, by default, cached. Either end of the
communication can decide to close a connection at any time (except
that a server shouldn't close a connection when there are requests
pending). In omniORB, you can configure how often the ORB scans for
idle connections with command line arguments. See section 7.3 of the
omniORBpy manual (or 8.3 of the omniORB C++ manual) for details. I
don't know about TAO.

Cheers,

Duncan.
