Attached is a new AJAX/IIS based VS2013 ASP.NET website project that interfaces to my Rain8Net HS2 irrigation-schedule script (also attached). I've never used AJAX with HS before - but I have not seen any over-loading issues so far. Also for the first time, I used the BackgroundWorker class in my HS2 script so that the long running schedule subroutine didn't cause the ASP.NET VB code to timeout. Any comments regarding the use of AJAX/IIS and/or the BackgroundWorker class with HS2 would be appreciated.
