- * $Log: yaz-z-assoc.cpp,v $
- * Revision 1.11 2000-09-04 08:59:16 adam
- * Changed call to logging functions (yaz_ added).
- *
- * Revision 1.10 2000/09/04 08:29:22 adam
- * Fixed memory leak(s). Added re-use of associations, rather than
- * re-init, when maximum number of targets are in use.
- *
- * Revision 1.9 2000/08/10 08:42:42 adam
- * Fixes for {set,get}_APDU_log.
- *
- * Revision 1.8 2000/08/07 14:19:59 adam
- * Fixed serious bug regarding timeouts. Improved logging for proxy.
- *
- * Revision 1.7 2000/05/10 11:36:58 ian
- * Added default parameters for refid to request functions.
- * Added default parameter for result set name to search and present request.
- * Commented out forced logging of PDU contents.
- * Added send_deleteResultSetRequest
- *
- * Revision 1.6 1999/12/06 13:52:45 adam
- * Modified for new location of YAZ header files. Experimental threaded
- * operation.
- *
- * Revision 1.5 1999/11/10 10:02:34 adam
- * Work on proxy.
- *
- * Revision 1.4 1999/09/13 12:53:44 adam
- * Proxy removes OtherInfo Proxy Address and Session ID. Other
- * Otherinfo remains untouched.
- *
- * Revision 1.3 1999/04/21 12:09:01 adam
- * Many improvements. Modified to proxy server to work with "sessions"
- * based on cookies.
- *
- * Revision 1.2 1999/04/20 10:30:05 adam
- * Implemented various stuff for client and proxy. Updated calls
- * to ODR to reflect new name parameter.
- *
- * Revision 1.1 1999/04/09 11:46:57 adam
- * Added object Yaz_Z_Assoc. Much more functional client.
