HttpPostJson2Async Example

Demonstrates use of the HttpPostJson2Async method. AutoIt

; happen if the task was canceled while waiting in a thread pool queue to be scheduled by Chilkat's
; background thread pool scheduler.  

; If the task was "aborted", it indicates that it was canceled while running in a background thread.  
; The ResultErrorText will likely indicate that the task was aborted.

; is determined by getting the result of the underlying method call.
