+/**
+ * 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.
