3.113.6. TCPPersistent Previous topic Parent topic Child topic Next topic

This parameter is obsolete since Radiator 4.20. Multiple outstanding queries are not supported by Net::DNS when using persistent sockets.
This optional flag tells Net::DNS to keep a TCP socket open for each host:port to which it connects. This is useful if you are using TCP and need to make a lot of queries to the same nameserver. The default value is false.
