Specifying the Backend Target

When the proxy accepts a Z39.50 client session, it determines the backend target by the following rules:

  1. If the InitializeRequest PDU from the client includes an otherInfo element with OID 1.2.840.10003.10.1000.81.1, then the contents of that element specify the target to be used, in the usual YAZ address format (typically tcp:hostname:port) as described in the Addresses section of the YAZ manual.

  2. Otherwise, the Proxy uses the default target, if one was specified on the command-line with the -t option.

  3. Otherwise, the proxy closes the connection with the client.
