Hello, Mark.
This is very, very strange. We most certainly tested cookies a lot and we run several applications using cookie auth with no problem: ASP.NET cookie functionality adds Set-Cookie response header every time.
We are attaching a test Visual Studio 2010 project that we re-tested cookie functionality with. Feel free to run it and try to reproduce the problem. If is has no problem, then please send us your application, if you can, so we could try it too - we definitely need to take care of this potential problem if it's there. To attach files to your postings you will need to create an account with the forum. Or you can
contact us to get our email address to send us your project privately.
Best regards,
UltiDev Team.
