/**
 * This class produces sockets for serving and submitting CORBA requests. The
 * socket factory can be set using {@link gnuOrb.setSocketFactory()} for
 * producting all sockets for that ORB. This is needed for using secure sockets,
 * for implementing the desired timeout policies, for HTTP tunnels and in some
 * other similar cases. While such functionality is provided by near all
 * existing CORBA implementations, no standard mechanism is defined.
 * 
 * The socket factory may need to put additional information to the IORs of the
 * objects, released by the ORB. Because of this reason, this interface extends
 * IORInterceptorOperations.
