+  // = TITLE
+  //     TAO_Connection_Handler
+  //
+  // = DESCRIPTION
+  //     This class is an abstraction for the connection handlers. The
+  //     connections handler in every protocol can derive from this
+  //     class as well as the ACE_Svc_Handler specialised for the
+  //     right protocol. This way, most of the common code for the
+  //     different protocls would be in this implementation. Further,
+  //     this class wold be of immense use in storing the handlers in
+  //     the Cache for TAO. This would help in purging entries which
+  //     is generally accompanied by closing the open handles and
+  //     deleting memory associated with the handlers.
+
+  //     Note: This class has NOT abstracted the GIOP specific
+  //     details. It is just to be safe so that, we can reuse this
+  //     class for any messaging protocol underneath. This way we need
+  //     not touch the Cache setup even when  using other protocols (I
+  //     mean messaging). BUT, I doubt whether this abstraction will
+  //     satisfy the needs of other messaging protocols. (will not?).
