- * Revision 1.5 1999-04-09 11:46:57 adam
+ * Revision 1.7 1999-04-21 12:09:01 adam
+ * Many improvements. Modified to proxy server to work with "sessions"
+ * based on cookies.
+ *
+ * Revision 1.6 1999/04/20 10:30:05 adam
+ * Implemented various stuff for client and proxy. Updated calls
+ * to ODR to reflect new name parameter.
+ *
+ * Revision 1.5 1999/04/09 11:46:57 adam
* Added object Yaz_Z_Assoc. Much more functional client.
