[Default: HttpAuWriter for ZK CE and PE, or SmartAuWriter for ZK EE]
It specifies which class is used to implement the AU writer. The AU writer is used to generate the output and send it to the client. The class must have a default constructor (without any argument), and implement the AuWriter interface.
There are two built-in implementations, HttpAuWriter and SmartAuWriter. The former one sends the output the client after the requests are processed completely. On the other hand, the later one will send a partial output first if the processing is taking too long (half of the value specified in the resend-delay element). By sending the partial output, the client will know if the server is still alive.
