Cookie Security: Cookie Not Sent Over SSL

is it possible to configure "require ssl" set in the web.config file

https://technet.microsoft.com/en-us/library/cc771633

and does it only work with authentication mode="Forms" and not windows auth?

I do have the HSTS setting globally configured on the IIS server
