Callback
The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).
The callback for the getResponseData([callback]) method is defined as:
function(err, buffer){ }
'err' is the error that occurred. If there was no error, then 'err' is 'null'.
'buffer' is the value returned by the method.
The callback for the setResponseData([callback]) method is defined as:
function(err){ }
'err' is the error that occurred. If there was no error, then 'err' is 'null'.
'err' has 2 properties which hold detailed information:
err.code err.message
Remarks
When the class is operating in client mode (i.e., the Listening property is disabled), this property is populated with the data included in incoming responses (if any) anytime the RequestComplete event fires.
When the class is operating in server mode (i.e., the Listening property is enabled), this property specifies the data that should be included in outgoing responses (regardless of whether they are sent immediately after Request fires, or later using SendResponse or SendNotification).
This property is not available at design time.
