- * Revision 1.4 1999-03-23 14:17:57 adam
+ * Revision 1.9 1999-12-06 13:52:45 adam
+ * Modified for new location of YAZ header files. Experimental threaded
+ * operation.
+ *
+ * Revision 1.8 1999/04/28 13:04:03 adam
+ * Fixed setting of proxy otherInfo so that database(s) are removed.
+ *
+ * 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.
+ *
+ * Revision 1.4 1999/03/23 14:17:57 adam
* More work on timeout handling. Work on yaz-client.
