Want simple JS demo

[Kristy]

JNP's demo works fine and should work fine in any IW 15.x version.
I wonder what's the problem you are facing. Several users are running Http.sys applications in production for several months and there is not a single report of problems due Http.sys.

Have you tried a simple Indy SA server? What's the error you are getting?

I tried that on my new Dell notebook, brought at three week ago.
Flash install Delphi 10.3.2 + Intraweb 15.1.3
http.sys will hang then windows blue screen
indy SA server is work
but WebApplication.ShowMessage('12345678'); no message show and no error message.
Jose's demo work as display, but can't assign value to variable.
Try VCL windows application, everything ok.
