+Custom Payload
+==============
+Native protocol version 4+ allows for a custom payload to be sent between clients
+and custom query handlers. The payload is specified as a string:binary_type dict
+holding custom key/value pairs.
+
+By default these are ignored by the server. They can be useful for servers implementing
+a custom QueryHandler.
