iControl API Validation
The WebAccelerator WSDL, and API shows the invalidate methods return ‘void’, which means I can’t get a positive confirmation that my “invalidate” messages are received and processed successfully

As with all of our API methods that have no return type, if you get a valid return, then that implies that the method succeeded. If it failed for any means, then a SOAPFault will be returned to your calling application and you can get the exception details in the response.
As for the WA Proxy methods, I'm not sure whether successful calls are logged, but I would assume that they are not. You will need to rely on the lack of an exception in the response as your positive confirmation.
