- * $Log: yaz-proxy-main.cpp,v $
- * Revision 1.8 2000-07-04 13:48:49 adam
- * Implemented upper-limit on proxy-to-target sessions.
- *
- * Revision 1.7 1999/12/06 13:52:45 adam
- * Modified for new location of YAZ header files. Experimental threaded
- * operation.
- *
- * Revision 1.6 1999/11/10 10:02:34 adam
- * Work on proxy.
- *
- * Revision 1.5 1999/04/21 12:09:01 adam
- * Many improvements. Modified to proxy server to work with "sessions"
- * based on cookies.
- *
- * Revision 1.4 1999/04/09 11:46:57 adam
- * Added object Yaz_Z_Assoc. Much more functional client.
- *
- * Revision 1.3 1999/02/02 14:01:21 adam
- * First WIN32 port of YAZ++.
- *
- * Revision 1.2 1999/01/28 13:08:45 adam
- * Yaz_PDU_Assoc better encapsulated. Memory leak fix in
- * yaz-socket-manager.cc.
- *
- * Revision 1.1.1.1 1999/01/28 09:41:07 adam
- * First implementation of YAZ++.
