* Sebastian Hammer, Adam Dickmeiss
*
* $Log: yaz-ir-assoc.cpp,v $
- * Revision 1.4 1999-03-23 14:17:57 adam
- * More work on timeout handling. Work on yaz-client.
+ * Revision 1.11 1999-12-06 13:52:45 adam
+ * Modified for new location of YAZ header files. Experimental threaded
+ * operation.
*
- * Revision 1.3 1999/02/02 14:01:19 adam
- * First WIN32 port of YAZ++.
+ * Revision 1.10 1999/04/29 07:33:28 adam
+ * Changed setting of host in connect/proxy setting. YAZ' strtoaddr now
+ * ignores database part of host.
*
- * Revision 1.2 1999/01/28 13:08:43 adam
- * Yaz_PDU_Assoc better encapsulated. Memory leak fix in
- * yaz-socket-manager.cc.
+ * Revision 1.9 1999/04/28 13:29:14 adam
+ * Yet another fix regarding database settings.
*
- * Revision 1.1.1.1 1999/01/28 09:41:07 adam
- * First implementation of YAZ++.
+ * 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.
