I have been developing a web application that communicate with my Web Core API via AJAX.
After my PC has been upgraded from windows 8.1 to windows 10 it no longer does so.
The error messages are letting my know that they are no longer on the same domain.
So I could start implementing CORS functionality, but I really do not want to have to use usernames and passwords in the AJAX calls, which would appear to be what I will have to do to prevent 401 unauthorised errors.
I have already put httpProtocol custom headers in my web.config file.
But why did this happen in the first place and can I put it back again?
