  49  * for implementing the desired timeout policies, for HTTP tunnels and in some
  50  * other similar cases. While such functionality is provided by near all
  51  * existing CORBA implementations, no standard mechanism is defined.
  52  *
  53  * The socket factory may need to put additional information to the IORs of the
  54  * objects, released by the ORB. Because of this reason, this interface extends
  55  * IORInterceptorOperations.
